EE Architecture ｜ Central Computing+Regional Control Architecture Information of Domestic Mainstream OEMs

The development of intelligent cockpit, intelligent driving and intelligent network will promote the continuous increase of new functions. At the same time, the demand for high computing power and large bandwidth data transmission will become more and more urgent, coupled with the concept of "software-defined car", which will jointly promote the upgrading and transformation of the whole vehicle EE architecture; At present, various car companies have gradually started to move from the distributed architecture with independent functions to the domain control architecture with integrated functions, and will eventually move to the centralized architecture with central computing and regional control.

One,Tesla’s "quasi-centralized architecture" leads the trend.

1. Distributed architecture VS centralized architecture

1) Under the distributed architecture, software and hardware are closely coupled, and OEM is more dependent on suppliers. In the process of cooperation, only one technical standard (such as communication information -XX signal, communication form -CAN/LIN, etc.) is provided to Tier1, and each system is provided by different suppliers, resulting in OEM’s vehicle software becoming a mixture of many independent and incompatible software systems. If the OEM wants to change or add new functions, it needs to talk with different suppliers, so it is obviously constrained by suppliers.

Secondly, with more and more ECU, the wiring harness in the car will become longer and longer, which not only increases the weight and cost of the car, but also brings great trouble to the layout and assembly of the car. Moreover, the computing power of each ECU can not be coordinated, resulting in a great waste of computing power.

2) Under the central computing+regional architecture, the computing power is gradually concentrated in the center. First, multiple ecus are merged into a domain controller, and then the domain controllers will continue to merge, eventually forming the ultimate layout of a central computing platform +N regional controllers. At this time, the number of ECU will be greatly reduced, which not only reduces the application cost of ECU and the wiring cost between controllers, but also contributes to the lightweight design of the whole vehicle.

Secondly, the sensors and actuators are connected to the nearby regional controllers, which can better realize the expansion of hardware. At the same time, the structure of the regional controller is easier to manage, and it is easy to realize the automatic assembly of the wiring harness.

2. What is Tesla’s "quasi-centralized architecture"?

In 2019, Tesla has realized the EE architecture scheme of central computing+regional controller on Model3, leading the trend. So what are the advantages of Tesla’s architecture?

The vehicle electronic and electrical architecture of Tesla Model3 is divided into four parts: CCM (Central Computing Module), BCM FH (Front Body Control Module), BCM LH (Left Body Control Module) and BCM RH (Right Body Control Module). CCM (Central Computing Module) consists of three modules: infotainment system (IVI), driver assistance system (ADAS) and communication system inside and outside the vehicle.

1）Front body control module:Responsible for the power distribution of the whole vehicle and the logical control and drive of the electrical appliances in the front compartment of the vehicle;

2）Left Body Control Module:Responsible for the power distribution, logical control and drive of the left-hand electrical appliances, including the convenience control of the left body and chassis control such as steering and braking;

3) Right body control module:Responsible for the power distribution of right-hand electrical appliances, the logical control and drive of right-hand and back electrical appliances, including the convenience control of right body, power system, air conditioning, etc.

Advantages of Tesla EE architecture:

1) The hardware part of the intelligent driving module adopts a self-developed FSD chip; For the software part, the operating system is customized based on open source Linux, and the middleware is developed by itself. The software and hardware are self-controllable, which not only helps to speed up the iterative update of vehicle functions, but also greatly reduces the development cost of the whole vehicle.

2) On the software architecture level, SOA architecture is adopted to facilitate the deployment of SOTA and the collection and analysis of cloud data.

There is no doubt that Tesla’s electronic and electrical architecture is advanced. Its central computing module -CCM integrates intelligent driving module, audio-visual entertainment module and in-vehicle networking module, and shares a liquid cooling system. Basically, the prototype of centralized architecture is realized, but it is not a centralized architecture in the strict sense. The industry calls this type "quasi-centralized architecture".

Therefore, even Tesla is still a long way from a truly centralized architecture. Considering the technical maturity and cost at that time:

1) The communication architecture is still relatively traditional, mainly based on CAN bus, and the control is still distributed on MCU, and the basic software of MCU adopts FreeRTOS.

2) The central computing module CCM is separated: only the MCU of audio-visual entertainment, the FSD of intelligent driving and the networking module inside and outside the vehicle are formally integrated on one board, but each module still runs its own operating system independently and completes its own tasks independently.

Even so, Tesla is still a practitioner of the most advanced concept of central computing+regional control architecture, which has triggered the learning and catching up of other peers in the industry.

Second, the "chaser" of the domestic Tesla EE architecture

In the era of intelligent and software-defined cars, whoever can master the dominance of EE architecture and software will occupy the commanding heights of the smart car market. Therefore, domestic mainstream vehicle companies are also actively carrying out relevant layout, and the mass production models of "quasi-centralized" architecture scheme will be launched around 2022-2023.

edit

However, the centralized architecture of OEM planning is not too unified in form. For example, the vehicle computing platform of SAIC Zero Beam adopts two HPC high-performance computing units; The scheme of GAC or Great Wall adopts three major computing platforms: central computing platform, intelligent driving domain and intelligent cockpit domain. But generally speaking, the R&D design concept is similar: the hardware adopts the architecture scheme of central computing+regional control, and the software adopts the design concept of SOA software architecture.

1. SAIC Zero Beam-Galaxy Full Stack 3.0 Scheme

Hardware platform:It consists of two HPC high-performance computing units, HPC1 and HPC2, and four ZONE controllers. Two high-performance computing units are used as the computing center of the whole vehicle to realize the functions of intelligent cockpit, intelligent driving and redundant backup of intelligent driving; Four area controllers are used to realize the related functions of different areas.

Remarks:

1) In August, 2021, SAIC Zero Beam and Xinchi Technology reached a strategic cooperation, and based on the Zero Beam Galaxy Full Stack 3.0 architecture, they will jointly formulate the development roadmap of the chip and vehicle electronic and electrical architecture; At the same time, the two sides will jointly explore and jointly develop a narrow operating system suitable for full stack 3.0 around the chip-level underlying software operating system and virtualization platform technology;

2) In September, 2021, SAIC Zero Beam announced that it had jointly designed and developed the HPC based on "Zero Beam Galaxy Full Stack 3.0".

Software platform:Adopt SOA integrated software platform of cloud management.

1) The software platform is decoupled from the hardware chip and the operating system. Even if the chip types and operating systems of different EE architecture platforms are different, the software platform can still be translated and reused. For example, Zero Beam’s 1.0 architecture platform and 3.0 architecture platform still use the same software platform, although the underlying hardware and operating system are different.

2) In the application layer, through middleware and SOA atomic service layer, a unified and standard API interface can be provided upwards, which makes the application layer development easier and more reusable. At the same time, coupled with the software platform SDK, OEMs, suppliers, third-party developers and users can all join in the application development and realize the co-creation of application ecology.

2. Gac ean-Spirit architecture

1）Hardware platform:Spirit architecture consists of digital mirror cloud, three core modules and four regional controllers (left/right/front/back). Among them,The three core computer modules include central computing unit, intelligent driving domain control module and cockpit domain control module; The central computing unit covers the new energy control module and the body control module, and is responsible for controlling the functions of vehicle running, braking and vehicle equipment.

  • The CPU is equipped with NXP S32G399 gateway computing chip, which is composed of 8 A cores and 4 M cores, and has built-in LLCE+PFE acceleration engine, and the communication delay is ≤ 20μ s.;

2) Software platform:SOA software architecture with layered design is adopted.

  • Basic intermediate layerAdopt atomic service encapsulation and standardized interface;
  • Dedicated intermediate layerAdopt enhanced combination service, which can be executed independently;
  • APP software layerIs an independent component decoupled from the bottom layer and can directly call the service.

The software architecture realizes service, atomization and standardization of components, decoupling of software and hardware, improving the ability and speed of OTA, and realizing plug and play of hardware-adding new application modules can realize new scenarios.

3. Great Wall Motor-GEEP4.0 architecture

1) Hardware platform:GEEP4.0 architecture consists of central computing platform (CCU), intelligent cockpit module (HUT), intelligent driving module (ICU), and three regional controllers (VIU_L, VIU_R and VIU_F).

Central computing unit CCUThe main responsibility of CCU is to deal with the functions of auxiliary autopilot, power, chassis, car body, air conditioning, car body status and mode management in a centralized way. Under the high-order autopilot configuration, CCU can be used as a backup of L3 domain controller to achieve the lowest risk conditions.

3 regional controllers:Is a standardized control unit.,Divide, deploy and develop according to the body domain, and arrange them on the left, right and front respectively, which is responsible for integrating some MCU around, that is, integrating ECU, power supply, controller and input/output. At present, most of the software algorithms of the three VIUs have been moved to CCU and developed by Great Wall Software Team. VIU only keeps a small part of logic, and it is more responsible for driving I/O.

4. Tucki X-EEA3.0

In November 2021, Xpeng Motors released the Tucki G9 at the Guangzhou Auto Show, which is scheduled to be listed in 2022; The car adopts Tucki’s brand-new X-EEA 3.0 architecture. At present, the official customs of Tucki has not revealed too many specific technical details. The author has compiled the following information for your reference:

  • Hardware architecture:Central supercomputing+regional control;
  • The software platform architecture is divided into three layers.System software platform, basic software platform and intelligent application platform;
  • Communication architecture:Adopt gigabit Ethernet communication;
  • Data schema:Realize non-inductive OTA- The domain controllers all control the memory in partition isolation, one area is used for upgrading and the other area is used for normal operation of vehicles; Therefore, even when the vehicle is driving normally, OTA upgrade of new functions can still be carried out at the same time;
  • Power architecture:The power supply of electrical equipment is controllable, and intelligent and accurate power distribution is carried out according to user scenarios, which reduces unnecessary power waste and optimizes the use of electricity.

Third, the impact of the upgrade of EE architecture

1. Reshaping the supply chain system

Under the traditional distributed architecture, the software is highly coupled with ECU. OEM has a strong dependence on Tier1, which is dominant, and the software and hardware are directly supplied to OEM by packaging. The industrial chain is relatively simple, with software product suppliers/chip suppliers (Tier2) in the upstream, component integrators (Tier1) in the midstream, and vehicle integration plants (OEMs) in the downstream.

With the upgrading and transformation of electronic and electrical architecture, the hardware is gradually standardized, the software is separated from the hardware, and the software and hardware are decoupled, making it a reality to define the automobile by software. Therefore, OEM’s ability to master software-defined cars has become more intense, and they hope to gradually regain the long-awaited "dominance" from Tier1.

To this end, enterprising OEMs began to set up software teams to improve their software research and development capabilities, but there is still a long way to go. In this context, some people have seen the strong demand of car companies for the "self-developed and controllable" cooperation mode, so a new species-Tier 1.5 has emerged, which can support the customization of OEM products upwards and integrate and integrate Tier2 resources downwards, in order to get a share of this "dominance" battle.

At the same time, in order to maintain its dominant position, the traditional Tier1 has also started to vertically integrate and build the R&D capability of the whole stack of software and hardware, transforming from a component supplier to a system solution provider, that is, upgrading from Tier1 to Tier0.5-it can not only provide OEM with software and hardware integrated products, but also provide full-process services from pre-technical research and development to post-data sharing, hoping to maintain a "close" relationship with OEM.

2. Changes in the industry competition pattern

At present, enterprises engaged in research and development of advanced EE architecture can be roughly divided into three categories: vehicle enterprises, Tier1 and technology companies. Vehicle companies have a strong motivation to master the core technology and component dominance of centralized EE architecture, because they have already seen the benefits that this dominance brings to Tesla. However, in the short term, there are still a few vehicle companies that can realize all the self-research of these technologies and components. Most vehicle manufacturers will still rely on Tier1, technology companies and other suppliers to complete it together.

The development project of the vehicle electronic and electrical architecture is complex and the technical link is long. Only the players in the industrial chain can cooperate with each other in each link, give full play to their respective advantages, and form a joint force to achieve the effect that 1+1 is greater than 2. Only in this way can we help the whole vehicle enterprises to complete the upgrading of the architecture more quickly.

For OEM, we will choose the cooperation mode that suits us according to our actual situation:

1) For head car companies with strong R&D capabilities, such as Tesla, they will choose self-research in key core areas such as chip, operating system, middleware and domain controller system integration, while outsourcing some hardware production.

Secondly, the automatic driving perception algorithm is relatively complicated. Even some head car companies will choose to jointly develop the perception algorithm with software companies with strong strength in the industry. In this process, most of them will also learn from teachers, gradually improve their perceptual algorithm ability, and finally move closer to the goal of self-research in the whole stack.

2) For car companies with relatively weak software research and development capabilities, it is necessary to distinguish what is common and what is individual. Considering its own research and development strength and cost pressure, the common part can only be strategically abandoned and handed over to the right supplier to help it complete the development; For the part of personality, you need to do your best to differentiate and create your own brand power. For example, a domain controller or a central computing platform needs Tier1 or a software company with full-stack R&D capability to help it gradually open in layers, and then do personalized and differentiated development at the application layer.

At present, the demand of the main engine factory is personalized and diversified, and most of them tend to ask suppliers for customized development according to their own needs. At the same time, OEM is also trying to improve its own software development ability; In the long run, for Tier1 and the technology companies that intend to do Tier1, it is a general trend that the development rights of some software functions of domain controllers or central computing platforms are "taken back" by OEMs. Therefore, Tier1 and technology companies are also striving to build full-stack technology research and development capabilities for software and hardware to avoid becoming "hardware foundries" for OEMs.

3. The new opportunities brought by the upward breakthrough of EE architecture

In the critical period when intelligent driving entered the second half of the competition, OEM began to upgrade its electronic and electrical architecture to cope with the development of automobile intelligence and networking. In this critical time window, whoever can help OEM to take the lead in realizing the rapid replacement and iterative upgrade of hardware modularity, as well as the portability and maximum reuse of software modules, will win the favor of the OEM and gain a foothold in the new market.

The so-called times make heroes, so which types are more likely to appear "heroes" on the "new outlet"? The author judges that there will be the following types:

1) Dali AI Chip Company-the electronic and electrical architecture is developing rapidly towards domain centralization and central domain control. For OEMs, the choice of high-performance Dali computing platform is a top priority. Therefore, the suppliers of large computing chips will usher in a growing market space. In particular, some chip companies that have recently grown up in China-open system solutions, ability to understand localized scenes, and good engineering supporting services are their current advantages.

2) Domain Controller Integrator-With the upgrading of the electronic and electrical architecture of the whole vehicle, the penetration rate of domain controllers has been promoted, and the emerging market of domain controllers will have great growth space in the future. Domain controller integrators with reliable product quality, which can also greatly save costs and shorten the development cycle for OEMs, will usher in an opportunity for development.

3) Supplier of basic software platform-For the OEM with weak software power, there is no need to re-develop the common part of the basic software platform, because it will not be perceived by consumers. Therefore, you can choose to give this part to the appropriate basic software platform supplier, which can not only reduce your development difficulty and cost, but also use your own manpower and financial resources for the key personalized development part; It is conducive to shortening the product development cycle and bringing it to market as soon as possible.

4. What are the challenges to realize the central computing+regional control architecture?

1. The bottom "chip" foundation determines the height of the upper "architecture"

High-order autonomous driving requires more and more computing power. Carrying chips with more advanced process and stronger performance has become the primary problem to be considered in architecture design, because the mass production time of the planned chips will affect the landing time of the architecture scheme.

When designing the central computing+regional architecture, the central computing platform needs to meet the needs and characteristics of all domains at the same time. Therefore, it needs more powerful chips and a combination of various operating systems. The biggest challenge is to select the available chips. However, at present, there are no mass-produced chips that can meet the requirements of several functional domains at the same time, so most OEMs still adopt the scheme of piecing together multiple chips:

1) Vehicle control system: Generally, MCU is adopted, which runs mature Classic AUTOSAR basic software, which requires high real-time performance and safety level, but its computing power and storage are limited.

2) Intelligent cockpit and intelligent driving field need high-performance and powerful SoC chips, and also need to run complex operating systems, supplemented by middleware.

Secondly, there are more and more players in the field of in-vehicle with high computing power and high performance chips, and the iteration speed of chips is getting faster and faster. If the whole technical architecture needs to be reconstructed every time the chips are replaced, it will seriously affect the development speed of new products. Therefore, the central computing platform needs to have good expansibility, not only a unified sensor and peripheral interface, but also good chip compatibility.

2. Software Capability and Software Team Building

Software capability At present, the mainstream functional domain architecture can be divided into five domains: body domain, chassis domain, power domain, intelligent cockpit domain and autopilot domain. In the process of developing to a centralized architecture, cross-domain integration is inevitable, such as integrating the body domain, chassis domain and power domain into a vehicle control domain, and the ultimate goal in the future is to integrate all functional domains into a central brain. In this development process, not only need to build a large number of software function service capabilities; At the same time, powerful software capabilities are needed to cope with the system collaboration among the underlying real-time operating system, AUTOSAR and other key software modules.

Another embodiment of software capability is that OTA, especially FOTA, requires OEM to have strong software development capability and be able to develop the control software of the underlying executive parts, so as to truly realize the function or performance of software-defined cars.

In 2018, the American Consumer Report magazine pointed out that Model3 had serious problems in emergency braking at high speed. When Model3 is driving at 60 mph, its braking distance is about 46.3 meters, which is higher than other models in the same class. To solve this problem, Model 3 upgrades the firmware by pushing it remotely. The end result is that the emergency braking distance of Model3 is shortened by about 6.1 meters through OTA.

The hardware of the Model 3 braking system is Bosch’s iBooster, but the electric control software at the bottom is developed by Tesla, so the characteristics of the brake pedal can be adjusted through OTA upgrade, that is, the braking force can be optimally distributed during the whole braking process by adjusting the braking response curve, thus shortening the braking distance.

Software team building- If OEM wants to realize the real software-defined car, that is, most functions and performances of the car are defined by itself, then its own research and development ability, especially the software research and development ability, will be a big test. Now powerful OEMs are setting up software R&D teams on a large scale, and software developers are obviously in short supply in the talent market. Even if you are willing to "seduce" with high salary and options, it is difficult to "set" the right talents. At the same time, the management and coordination of software teams are also complicated, which is where traditional OEMs need to carry out intensive learning again.

3. The problem of organizational system

Traditional OEM has a R&D team, a product system and a supply chain system that have been gradually built and improved for many years. However, there will be more things to consider and worry about when the whole vehicle EE architecture changes, such as the reusability of the original production line, the compatibility of the architecture with the huge product line, and the supply chain problems around the world.

A major feature of the centralized architecture is that the computing power is concentrated in the center. In this case, many ecus will definitely be cut off. If a large number of ECU’s are cut off in the car, it is a matter of life and death for employees who rely on these parts and related suppliers. If they can’t make internal and external adjustments, it will be difficult for the new architecture to be promoted and implemented quickly.

To some extent, the traditional OEM has become a "double-edged sword" by virtue of the advantages of supply chain and product system accumulated over the years, and it has begun to hinder them from carrying out architectural innovation. Therefore, it is impossible for them to "cut across the board" when carrying out the structural reform, completely demolish the previous scheme and switch to the new E/E architecture. They can only use the existing resources to make a gradual transition and evolution, and gradually improve their own software R&D capabilities and change their R&D organizational structure to adapt to the new R&D process.

The new forces that build cars have no concerns in this regard, and they can start from scratch. Although it doesn’t accumulate as many past resources as traditional OEM, and it doesn’t have the previous historical burden, it can make new attempts without scruple.

Therefore, from this point of view, the huge organizational system of traditional OEMs has really held them back.

Luhan and Yang Ying are hot searches for new dramas. Can they make a comeback by acting？

1905 movie network feature Recently, there has been a new "see you for a long time" in the entertainment industry.A representative of a male artist who has been criticized for his poor acting skillsLuhanAnd traffic female artist representativesYang Ying, because of the hot search before and after "acting progress" in the new work. "Melon Eaters" was full of question marks, and found that this didn’t seem to be a marketing account "embarrassment", and the quality of the two new dramas was indeed good.


The online drama "Crossing the Wire" starring Lu Han has a good reputation, with a score of 8 points on Douban. The topic of #Luhan’s acting #was listed on Weibo’s trending topic list, and netizens have said that "Luhan’s acting has improved" "Breakthrough is great" "Looking forward to Luhan in" Doom "in the future."


Another film starring Yang Ying, "Skyscraper", also scored 8.1 points on Douban, and the topic of #YangYing crying drama also triggered a heated discussion among netizens. According to the poll, more than 54% of netizens believed that his "acting has improved" and "saw efforts".


Zhang Ziyi’s Weibo post commented on Yang Ying’s sincere and natural performance, and some media posts said that the two finally ushered in a comeback in their acting skills.


This time, Lu Han and Yang Yingzhen’s acting turned around?Today we specially invite film critic Ai Hui to join us in paying attention to the actors Lu Han and Yang Ying who have recently been talked about for their acting skills.


Luhan | Looking for "Me in the Play"



In the online drama "Crossing the Line of Fire", Lu Han and Wu Lei play two e-sports players who originally belonged to different time and space but met in the game map. The character Xiao Feng played by Lu Han belongs to 2008, when e-sports has not yet ushered in its best era. Xiao Feng’s team has been misunderstood and ridiculed, but he has always adhered to his dream.



"His speaking skills still need to be improved, but this time he created a good atmosphere," Ai Hui said after watching a clip of Lu Han’s performance live, adding bonus points from styling to details.


"First of all, he is not the kind of’idol drama ‘style, which is closer to life; second, his performance in details is very life-like. During the crying scene, he naturally wipes away tears with the back of his hand," Ai Hui analyzed. Coupled with slightly swollen eyes and messy hair, these details help to pull the audience into the story.


Referring to the works that Lu Han had previously been questioned about performing, Ai Hui said that for Lu Han, whose performance level is at a "relatively basic stage", it is very important to find a role that suits him.Playing the e-sports player this time is a very smart choice – he already plays video games, "he doesn’t need to do a lot of homework to understand the character". When he fully unleashes his true self, the effect naturally exceeds the audience’s expectations.


Another work starring Luhan, "Doom Escaped", also officially met the audience. "I think Luhan’s performance in it is worth looking forward to", Ai Hui is optimistic about Luhan’s new work.In the play, he plays a rebellious teenager. "I think he has started to figure out what acting is, and Lu Han may slowly find a feeling in such a team," Ai Hui said.


Yang Ying | Actress "doesn’t have to be beautiful"



Compared with Luhan’s wide-ranging praise, Yang Ying’s new work brought more controversy under the topic of #angelababy crying scene #hot search. "The crying scene like a porcelain doll" sparked a heated discussion among netizens, "She wants everything to be beautiful and exquisite," Ai Hui commented.



"Yang Ying should be making progress," Ai Hui said affirmatively. "She’s crying because she couldn’t cry before." But her movements "can sum up the routine," such as blinking your eyes when you express curiosity and shock, and then moving your lips a little; when you cry, look at the sky, and then shake your hair. "Ai Hui believes that Yang Ying’s performance mode always satisfies a certain" standard aesthetic feeling. "


"She may not have been born at the right time," Ai Hui sighed."If she was in the same era as Li Jiaxin, she might not have encountered so many criticisms of her acting skills," Ai Hui analyzed, "because Li Jiaxin’s acting skills are not good, but she met a director like Wong Kar-wai. In the Hong Kong film industry at that time, there was a type of film that needed to be amplified infinitely."


"What kind of acting do you think she did? No, she just had to stand in front of that camera and ask Du Kefeng to find a fisheye photographer, and you would feel that she did well."


Yang Ying did take on many similar roles, and the performance in the movie was a typical "Yang Ying-style performance"."There are not many lines, but they are beautiful enough to make people feel amazing; when you don’t speak, your eyes are smart enough," Ai Hui said. In other words, she herself and the team are notoften clearlyKnow, "Which roles are more pleasing to her next".


"I think the first thing she has to do is break through her one-sided thinking about actors, that is, actors don’t have to be beautiful, let alone be ugly, and first act like an ordinary girl," Ai Hui said. To Ai Hui, Yang Ying "still hasn’t done it" at present.In fact, actors who are idols like Lu Han and Yang Ying often bear more attention in their acting skills.


Over the years, they have been trying their best to prove themselves by using their acting skills. The surprise that Jackson Yee brought to the audience in last year’s film is also an important node for the idol actors from a certain perspective. "Everyone is no longer judging the traffic stars as they used to be. This is a very benign stimulus."


For the average audience, a simple judgment is the character’s credibility and attractiveness. "If Yang Ying and Lu Han keep playing, maybe at a certain corner, there will be a character they understand very well and finally show a good effect. Always stick to it," Ai Hui said.


Welfare+guarantee, ask the new M7 new gameplay to promote the big decision. In 45 days, 70,000 sets have been broken!

There are still two months to the end of the year, and the automobile market is surging. In order to occupy the automobile market, major automobile brands have come up with unique tricks. Among them, the unique marketing strategy of the new M7 in Wenjie has gained widespread attention in the market. It is understood that Huawei not only provided 30,000 yuan worth of rights and interests for the new M7, but also promised to delay the delivery of subsidies for 200 yuan/day, providing consumers with a car purchase experience of "having benefits on the top and being guaranteed on the bottom", creating a record ceiling of 70,000 units in 45 days.

Different from the strategy of focusing on "promotion" when new cars of other automobile brands go on the market, Huawei has taken a different approach to stand on the side of consumers, dig deep into consumers’ needs, and introduce rights and protection at the same time. Specifically, the big rights and interests of this new car include:

(Time: 10.8-10.31)

(1) enjoy 5,000 yuan to deduct 8,000 yuan, and reduce the final payment;

(2) a gift of 12,000 yuan worth of interior and exterior decoration matching gold;

③ Enjoy the matching rights worth 15,000 yuan (as described below);

Max smart driving edition users can deduct the optional ADS2.0 urban navigation NCA function by equal amount;

Plus rear-drive users can choose and install a technology enjoyment package worth 15,000 yuan in equal amount;

Users of all models can also choose a combination of rights and interests with a value of 15,000 yuan (21-inch wheels with a value of 10,000 yuan and one of the original aftermarket products).

In order to make consumers worry-free about buying a car, Huawei has also made a care plan for the new M7. According to this plan, new M7 users who have completed the big payment before November 30, 2023, the order status on AITO App starts from the date of "delivery plan confirmed" to the date of "vehicle has arrived at the store". If the waiting period in the table below is exceeded, they will receive the cash subsidy for car pick-up care according to the number of days (vehicle arrival date-delivery plan confirmed date-waiting period). The standard of overdue subsidy is 200 yuan/day, up to 10,000 yuan.

On the basis of marketing strategy innovation, Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, personally promised that Celeste Smart Factory is working overtime to ensure market supply demand. At the same time, the investment in the supply chain has exceeded 1 billion yuan, and new production shifts are running around the clock 22 hours a day, making every effort to ensure delivery. This wave of operations makes consumers satisfied with Huawei’s strength and commitment.

The new M7 in Wenjie broke through the large quota of 50,000 orders in 25 days, reaching 60,000 orders a month, and the quota has exceeded 70,000 units in 45 days! Such achievements are remarkable. Of course, the new M7 has achieved such good results, not only relying on welfare and rights, but also relying on Huawei’s strong product strength and user orientation.

Empowered by Huawei, the new M7 intelligent driving field in the world is far ahead. At present, the new M7 intelligent driving version of Wenjie has completed the OTA upgrade, and supports the functions of high-speed NCA and urban LCC. On high-speed and elevated roads, vehicles can follow the navigation to their destinations, and consciously identify the signal lights to assist in controlling normal driving, intelligent lane change, intelligent speed limit, etc., which greatly liberates drivers from manipulating characters. It can also show its talents in urban roads, cruise at a fixed speed, follow the car, cross corners, etc. in the traffic flow, and it can also realize automatic avoidance in and out of the lane, greatly improving driving safety and happiness. It is worth mentioning that Huawei also uses technology to make parking more self-free. Because of the launch of the custom parking function, users can drag and drop vehicle icons on the ground where parking is allowed but not marked. A temporary parking space is supported with the narrowest width of +0.4m, and there is no need to ask an old driver for parking.

Not only that, but the new M7 in space and interior also shows amazing strength. In terms of interior space design, the new M7 in Wenjie has gained more effective interior space with a smaller "pool" through excellent design and layout optimization, with a "room occupancy rate" of 66.3%, leading the same class, and both front and rear rows can get a very spacious and comfortable experience. Moreover, in order to further improve the experience of drivers and passengers, the seats of the new car are designed with 10 layers of comfort lamination, with a total foam thickness of 100mm, and four seats are equipped with ventilation, heating and massage functions as standard, which can bring drivers and passengers a comfortable experience like first class. In addition, thanks to Huawei’s strong technical strength, the car’s Xiaoyi intelligent assistant can greatly liberate the user’s hands, and the double-row nap function of the main and auxiliary drivers can be turned on through voice, bringing more comfort, intelligence and fun to the user’s travel experience. In addition, the new M7 also provides a six-seat layout, giving consumers more car choices.

From the perspective of users, Huawei not only provides high-quality products and services, but also cares about the needs and rights of consumers. The new M7 in the world has won the favor of consumers through Huawei’s unique marketing strategy and caring plan, and soon became a hot model in the market after listing. If you have a car purchase plan recently, you may wish to take a look at the new M7 in the world. Now you can enjoy the rights and protection of buying a car, so act quickly!

Spicy Finance： Small hydropower is clean energy, why is it restricted to stop？

　　This year’s government work report proposes to make room for the development of clean energy. Although small hydropower is internationally recognized as clean energy, its development is restricted or even stopped in some places. There are more than 47,000 small hydropower stations in China. What will happen in the future?

　　"It is easy to build a river dam, will it have an impact on the ecology? The water was intercepted by the upstream, and what about the downstream water? " The social doubts about small hydropower mainly focus on three aspects: first, it will reduce the dehydration of river sections; second, the dam construction of small hydropower will cut off rivers; third, it will compete with the people for water.

　　The power stations built in the early days were limited by the conditions at that time, and some of them were unscientific in planning and design. In addition, they were once developed out of order, which really brought about the influence of river reduction and dehydration, and some river basins had problems such as river cut-off and water pollution and eutrophication.

　　Will these problems become the "fatal wound" of small hydropower? Should small hydropower be developed or restricted? Spicy Finance went to Fujian and Zhejiang, major hydropower provinces, and conducted an investigation and interview.

three

　　Small hydropower has great emission reduction benefits and high energy return rate.

　　Yongchun County, Fujian Province, is the birthplace of small hydropower in China. There are 220 hydropower stations in 750 kilometers of rivers. The small hydropower here has made farmers’ production and life inseparable.

　　There are 236 administrative villages in Yongchun County, and 122 villages have hydropower stations. More than 70% of the power stations are collectively managed by villages, with an average annual hydropower income of 200,000 yuan. Xianyan Hydropower Station undertakes the public welfare services of surrounding villages, and 10 villages enjoy preferential electricity prices, with 3 cents cheaper per kilowatt hour, which is nearly 700,000 yuan a year.

　　"Small hydropower itself does not draw water, which is a green project." Zheng Shuangwei, director of the county water conservancy bureau, said that the development of small hydropower will destroy the ecology, which is biased. After all, there are a few small hydropower problems. In fact, the negative impact of small hydropower can be minimized through technical means and management measures.

　　In the dry season of Qingyuan Power Station on the main stream of Taoxi River, the 7-kilometer-long reach is easy to dry up from the water intake to the water outlet of the power station. This is also a controversial dewatering section.

　　How to solve the problem of water reduction in river reach? In 2015, the power station was rebuilt, and 48 new drainage holes were added, from which gurgling water flowed into the river. "The measures are quite simple. With the drainage holes, the dry season will give priority to ecological protection. With a flow rate of 1 cubic meter per second, the river section will not be dehydrated." Lin Jingsheng, head of the power station, said.

　　During the "Thirteenth Five-Year Plan" period, Fujian will ecologically transform 500 small hydropower stations. By 2030, all power stations that cause serious dehydration will implement ecological flow.

　　Then, will the small hydropower dam cut off the river? Will it compete with the people for water?

　　Zhejiang encourages the ecological transformation of small hydropower stations, installing ecological units, adding water outlets and building dams. The province subsidizes 35%, and the city and county subsidize some more. Fenghuang Hydropower Station in Anji County has transformed into "small hydropower+water supply". There is a power plant under the dam and a water plant on the dam, and an ecological small unit is added. Last year, the water supply alone reached 10 million cubic meters. With the ecological flow, the downstream delivery port will be smooth and clear all the year round.

　　Small hydropower can not only generate electricity, but also has obvious comprehensive benefits such as flood control, irrigation and water supply. There are four reservoirs behind the 480 kW White Hydropower Station in Yongqiang District, Wenzhou City, Zhejiang Province. The flood was put into the reservoir area and the fertile land was irrigated.

　　"Small hydropower itself is no problem. Through scientific planning and strict supervision, some negative effects can be minimized." Cheng Xialei, director of the International Small Hydropower Center, said that not only small hydropower, but also any human activity has an impact on the ecological environment, and wind power and photovoltaics are no exception. The key is how to weigh the pros and cons and how to transform.

　　According to the data of international research institutions, from the perspective of energy return rate, hydropower is 170— 280, while wind power is 18— 34, solar energy is 3— 6. Traditional thermal power is 2.5— 5.1。 According to the research of china environmental science Research Institute, the benefit of reducing PM2.5 emission by small hydropower is more than 1.5 times that of wind power and solar power generation. In other words, small hydropower generates a lot of electricity, but the energy required for its own construction and maintenance is very small.

　　Accurate poverty alleviation, small hydropower shoulders the heavy responsibility

　　At present, the development rate of small hydropower in China is 59.2%, which is lower than the level of about 80% in developed countries. In Switzerland and France, the development rate of small hydropower is as high as 97%.

　　Most of the undeveloped hydropower resources in China are concentrated in 832 poverty-stricken counties. To win the battle against poverty, we must not only let the poor people get rid of it, but also let them have a stable income and a way to get rich. But at present, the biggest difficulty in industrial assistance is that there are too few good projects. Small hydropower projects, however, have little investment risk and market impact, and can bring long-term stable income. Local development and nearby power supply will help the poor realize the function of "hematopoiesis".

　　In 2016, the state allocated 300 million yuan from the central budget to carry out pilot projects of rural small hydropower poverty alleviation in six provinces and cities including Hunan, Shaanxi and Chongqing. According to the national regulations, after the completion of the poverty alleviation hydropower station, the poverty alleviation income funds will be paid to the county government where the project is located at a rate of not less than 6% of the central investment every year, which will be specially used to support the construction of local poor households and infrastructure.

　　The pilot project of rural small hydropower poverty alleviation in Shaanxi Province will be fully completed before the end of June, and the poor people will share the fruits of hydropower resources development. The four pilot projects in the province will provide no less than 3.4 million yuan of poverty alleviation income funds every year for poverty alleviation and improvement of local infrastructure.

　　Dongkou County and Xinhua County, Hunan Province, are located in the contiguous poverty-stricken areas of Wuling Mountain. Last year, the central government invested 10 million yuan and 29.8 million yuan respectively to build two poverty-relief power stations. Each year, the two power stations will allocate more than 2.4 million yuan as income funds for poverty alleviation, 80% of which will directly increase the income of poor households who have set up files, and 20% will be used for infrastructure construction in poor villages.

　　"Small hydropower has remarkable benefits in poverty alleviation, and I hope to increase policy support." Cheng Xialei suggested that the ecological electricity price mechanism is feasible, and an ecological compensation mechanism should be established as soon as possible in accordance with the principle of "whoever develops and protects, whoever benefits and compensates".

　　"It is worth noting that behind the restrictions on small hydropower, the installed capacity of coal-fired power is still expanding. In some places, water, wind and light are seriously abandoned. Only Sichuan and Yunnan provinces abandoned 80 billion kWh of water last year." Wang Yinan, a researcher at the Institute of Resources and Environmental Policy of the State Council Development Research Center, said that although the Renewable Energy Law clearly stipulates that hydropower is renewable energy, hydropower has not been able to enjoy the incentive policies for renewable energy such as wind power and solar energy for more than 10 years, and hydropower has been excluded from the full-guaranteed acquisition policy, which has hindered its consumption. At the national level, top-level design should be accelerated, local barriers should be broken, and hydropower should be included in the scope of full-guaranteed acquisition of renewable energy as soon as possible.

Herd immunity： Why does herd immunity in English use herd？

This article is reproduced from "A Zewai English Notes" and has been authorized.
At the beginning of the spread of the epidemic in March 2020, the British Prime Minister put forward the proposal of "herd immunity", which made many people feel "refreshing". At that time, the successful development of the vaccine against COVID-19 was still far away, and the British Prime Minister could only imagine the HERD Immunization achieved through "infection of diseases". This proposal with low safety attracted a lot of criticism at that time.
Since the beginning of this year, with the listing of various vaccines, safer herd immunity has become an important means to fight the epidemic. Countries are encouraging people to vaccinate, and strive to reach the vaccination scale needed to realize herd immunity as soon as possible.
Herd immunity will effectively reduce the negative impact of the epidemic and protect people’s health; This statement itself also contains a remarkable feature of English in language and culture, as well as the great differences between English and Chinese.
Before explaining English knowledge, let’s first understand the principle of group immunity.
What’s with Herd immunity?
The definition of Herd immunity is roughly as follows:
Herd immunity is a phenomenon seen when a high percentage of individuals within a population have developed immunity to a pathogen.Group immunity is a phenomenon: in a certain population, a large proportion of people are immune to a certain pathogen (such as bacteria or viruses).
Because so many people within the community are unable to contract the disease or virus, this reduces the likelihood that those who have not developed immunity will contract the disease. Because most individuals in this population have acquired immunity, they will not be infected with related diseases or viruses; In this way, the possibility and risk of exposure to related diseases or viruses will be greatly reduced for those individuals who have not acquired immunity in the whole population.
There are two ways to obtain immunity from a virus or bacteria: infection or vaccination. Comparatively, vaccination is the safer, more effective path, as it provides immunity without illness.
There are two ways to get immunity from a virus or bacteria: one is to infect the disease, and the other is to vaccinate. In contrast, the method of vaccination is more effective and safer, and it will not cause illness while generating immunity.
Different expressions for "group"
In English, there are several other expressions of held immunity, including community immunity, population immunity and social immunity, but in newspapers and media, most articles use the wording of held immunity.
The original meaning of the word herd in English is not used for "people", but to describe "groups of animals".
In practical use, herd mainly refers to cattle, and sometimes also refers to deer or elephants, such as: A herd of cows/deer/elephants and so on.
Using herd to refer to people is strictly an extended metaphor. In addition to newspapers and magazines, people are often referred to in various fictional novels, and the language effect is herd vivid, such as:
She pushed her way through a herd of lunchtime drinkers.
She struggled through the crowd who were having lunch and drinking.
Two idioms
Although the description of "crowd" with herd is vivid and interesting, its meaning is not completely neutral, and it is somewhat disapproving or even critical. It is emphasized that when many people get together, they often lose the ability to think independently as individuals.
Herd mentality or herd instinct, which is often used in English, is usually described as "herd mentality" in Chinese, which means: like flocks of animals and livestock, they have no thinking ability, only know that follow the herd takes action with the whole group; What most other members of the group do, they follow suit.
There is an idiom to ride herd on sb/sth in American English, which is often used to describe crowds. This idiom comes from the plains of the western United States, which reminds people of the scene of cowboys riding horses and herding cattle on the grassland.
Although it originated in the countryside, to ride herd on sb/sth is mainly used in urban areas, which refers to crowd control, usually refers to unorganized crowds, such as:
The police rides herd on crowds of youths on the streets.
The police kept order in the street to prevent groups of young people from getting out of control.
Situation difference
This figurative use of herd to refer to the crowd mainly exists in newspaper articles and literary novels, and is also used in popular science books for the public.
However, in academic articles and official documents of various institutions and departments, most people deliberately avoid using Herd to describe people. For example, in academic and formal occasions, herd immunity is usually replaced by community immunity and population immunity.
Although this will reduce the vividness of the language, it can rule out the possibility of association and avoid being offended. Although it is vivid, it is more objective and accurate.
cultural difference
Different from English culture, many other languages and cultures are not used to using words specially used to describe animals to describe human beings, and even are very taboo about it. This is the case in Chinese, and an obvious example is a large number of insulting expressions in traditional Chinese that originated from "dogs".
This cultural difference between Chinese and English deserves special attention when learning and using English. When translating English-quoted media articles, it is especially important to realize that when "animals" are used to describe "people" in English, they are usually not insulting, and they are not intentionally offending others and calling them "animals, pigs and dogs are inferior".
Most of the time, Herd’s analogy of "animal" to "human" can be directly translated into plain language without rhetorical meaning.
Two more "groups"
Realizing the cultural differences between Chinese and English in animal metaphor can also help us to use English more vividly and effectively, and we will not be timid because of this "burden" of traditional Chinese rhetoric expression.
English words like herd, which use animals to describe "people", are very rich and constitute a systematic series.
For example, herd is suitable for cattle, deer, elephants and other large animals; The "flock" of smaller animals is called flock in English, which mainly refers to sheep.
In addition, flock can also refer to a flock of birds, such as the proverbial birds of a feather flock together, which often corresponds to the Chinese word "birds of a feather flock together". When describing insects, such as bees, it will be called swarm.
Like herd, flock and swarm are often used to describe people, which not only remind people of vivid images, but also have their own division of meaning and function, describing different characteristics and aspects of "group behavior" respectively. In English, these statements are usually not regarded as insulting or demeaning.
