More interesting than Mate XT？ The M9 Five-seater Edition of the World is coming： Six major upgrades and blessings

Since the M9 went on the market for more than eight months, the cumulative order volume has exceeded 130,000 units, and it has won the domestic luxury car sales champion of more than 500,000 yuan for five consecutive months.

With a length of 5230mm, even if six seats are placed, the passengers in the car still enjoy extremely spacious interior space. Why did Huawei launch the big five-seat version, and the starting price is the same as that of the six-seat version? Which of the two cars is more worth choosing?

Compared with the six-seat version, the five-seat version of Wenjie M9 has been upgraded with six major features: intelligent lighting, intelligent space, intelligent driving control, active safety, intelligent assisted driving and intelligent parking assistance, but there are two main changes on the whole.The first is to launch ADS 3.0, which has improved intelligent driving, intelligent parking, intelligent driving control and active safety.

Intelligent driving has always been one of the core competitiveness of HarmonyOS Zhixing automobile products. In the past, ADS 2.0 version has realized the intelligent driving function available all over the country, and ADS 3.0 has gone further, achieving high-order intelligent driving that is available all over the country and easy to use on all sections, and can realize intelligent driving from parking space to parking space level.

The intelligent parking function of Wenjie M9 has also been upgraded, which not only supports broken roads and parking in extremely narrow parking spaces, but also supports the identification of parking space obstacles. After locking the parking space, the vehicle can automatically park. In terms of active safety, Yu Chengdong said that Huawei’s active safety function has successfully helped users avoid more than 560,000 possible collisions. Omni-directional Collision 3.0 integrates super-full perception, super-fast response and advanced authentication, which can effectively avoid the possibility of collisions from the front, back and side directions. The effective range of AEB is 4 km/h-150 km/h.

However, the difference in software level can be eliminated through OTA upgrade. Yu Chengdong announced that HarmonyOS Zhixing Zhijia vehicles will be upgraded to ADS 3.0 version one after another from September.

The second major change of the M9 five-seat version is the interior space. With the same body size, reducing a row of seats will naturally bring more interior and trunk space.The interior space of the M9 five-seat version is as high as 3500mm, which is better than those of Cullinan, Maibakh GLS 600 and Range Rover Zunrong Chuangshi Extended Edition. The 1043L super-large trunk can hold four 28-inch suitcases. The trunk of the car also supports sliding rails, with optional multifunctional loading trays or two seats.

Back in the car, the M9 five-seat version also supports the folding of the co-pilot seat and the folding of the middle parking space in the back row, which can free up a 1985mm "presidential space" for the boss in the back row, which is also far superior to other luxury cars. The front seats can also be laid down to form a big bed in the car.

Judging from the configuration changes, the five-seat version and the six-seat version of Wen Jie M9 are slightly different for the consumer groups.The six-seat version is aimed at individual users with more family members, and six seats can take more people, but the space in the back row and trunk is sacrificed to some extent. Although the big five-seat version lacks a seat, it has gained more space in the back row and trunk, which is suitable for business people with exclusive drivers and individual users who have less demand for seats.

The super-large internal space of the M9 five-seat version in the world brings higher comfort. The slide rail in the trunk can significantly improve the quality of life, whether it is installing a table tray for camping picnic or installing a seat for blowing and fishing. With the blessing of the big five-seat version, the M9 will also reach a new sales peak.

At the press conference, Yu Chengdong proudly said that the sales volume of luxury car products with a price of more than 500,000 yuan was not only the first, but also the combined sales volume of the second to tenth places in the list was not as good as that of the M9.

Indeed, the M9 claimed to be "the best SUV within 10 million yuan", not for other products with the same price, but for all luxury SUVs within 500,000-10 million yuan. With the functions of Turing chassis, Huawei’s intelligent driving function, HarmonyOS car system, and the linkage between people, cars and homes, the M9 has shown good competitiveness.

Nowadays, the five-seat version of the M9 in the world has arrived simultaneously with ADS 3.0. On the one hand, it has supplemented the five-seat product line of the full-size SUV in the world, and on the other hand, it has upgraded the intelligent driving ability of all the models in HarmonyOS Zhixing.

But these are not enough. At this conference, He Liyang, president of Sailis Automobile, also took the stage to speak. He said that Wenjie Automobile has ranked first in the new car quality performance of new energy brand in China and ranked first in the performance of luxury brand NPS (net recommended value) in China market. Next, Wenjie Automobile has to create new industry standards, build a new digital intelligence quality system, continuously upgrade the user service experience, and shorten the delivery time of new cars to 6-8 weeks.

With the blessing of Wenjie Automobile, Sailis Automobile, which suffered a loss for four years, made a profit for two consecutive quarters this year. Cyrus, who turned losses into profits, also showed stronger enthusiasm, and introduced the industry-leading 9800T super intelligent die casting technology, aluminum body cold connection technology, etc., and measured the product accuracy through robots to ensure product quality control. Another "lifeline" of luxury car brand-service, Sailis also continuously upgraded, and launched 18 online services +7 new initiatives to fully shape brand value.

HarmonyOS Zhixing intelligent car selection mode is very special, that is, it depends on the R&D and production capacity of car companies, and it does not rely on Huawei’s intelligence and brand blessing.The cooperation between Huawei and Cyrus is exemplary, and the success of the consulting industry has set an example for other car companies that have joined the car selection business of HarmonyOS Zhixing or have the idea of joining.

Nowadays, the influence of Wenjie brand has been formed, and Cyrus will also open its first brand flagship store in Beijing Oriental Plaza.The independence and perfection of offline stores is conducive to shaping the brand image and continuously enhancing the brand value. After making up the shortcomings of the product line, the M9 five-seat version of Wenjie may continue to erode the market share of joint ventures and imported luxury SUVs, helping Wenjie Automobile and HarmonyOS Zhixing to reach new sales peaks.

After the product line and service ecology are gradually improved, Huawei will also devote more energy to operating brands such as Zhijie, Enjoying and Zunjie.

Compared with positioning the prestige of the million-level market and the enjoyment of the executive-level market, product positioning and intellectual circles with slightly lower prices may be more important for Huawei. Zhijie is a sub-brand jointly built by Huawei and Chery, one of the five giants of its own brand car companies, but its product sales are not satisfactory.

At the end of the conference, Yu Chengdong also introduced the new car, Zhijie R7, which will be released soon. The car is also equipped with ADS 3.0, HarmonyOS cockpit 4.0, Turing chassis and other configurations, and based on the 800V platform, the cruising range has reached 802km, and there are also 837L trunk, 52L front reserve box, co-pilot zero-gravity seat, front door double-layer heat insulation/rear door double-layer privacy glass, electric sunshade and other configurations. The car has now started a small order, the pre-sale price is 268,000 yuan, and the deposit of 2,000 yuan can reach 5,000 yuan.

Nowadays, the brand situation in the world is very good, and five new cars have been launched while the iron is hot, and seven versions may be launched in the future, which will continue to benchmark Land Rover, Maibakh and other brands.Huawei will also spare its energy to build a brand of intellectual circles. The arrival of the intellectual community R7 is only the beginning, and there will be more cars and coupe SUVs in the intellectual community in the future.

Success can’t be achieved overnight, and the brand in the world of inquiry has experienced a low sales volume. However, the arrival of M7 and M9 made the world of inquiry reverse the situation and grew to be the first in the market of 500,000 yuan.Xiaotong believes that the intellectual world will be the same. After the product line is rich and covers more consumer groups, the sales volume will also usher in a skyrocketing period.

In the era of new energy vehicles, the competition in the whole industry will be more intense, even the old car companies may be eliminated. The situation of the brand of new forces with relatively weak background is even more severe, and the car in the world has successfully turned losses into profits, and has got tickets to enter the next stage of competition. However, HarmonyOS Zhixing is not only a sub-brand, but also brands such as intellectual community, respect community and enjoyment community grow synchronously, so that HarmonyOS Zhixing can get tickets for the new energy automobile giant club.The five-seat edition of Wen Jie M9 and the upcoming release of Zhi Jie R7 are a supplement to HarmonyOS Zhixing’s product line, and also the foundation for HarmonyOS Zhixing to accelerate its development and move towards a new era.

From September 6th to 10th, IFA (Berlin International Consumer Electronics Show) 2024 was grandly opened. China technology giants such as Lenovo, Glory, TCL, Hisense, Changhong, Jumbolong, Time and Space Pot, Cloud Whale, Xunmi, Jimi, Dangbei, Beisi, Lvlian, Insta360 (Shadow Stone), DJI and Laifen have gathered in Berlin and will soon release new products to show muscles on the world stage. The report group of IFA 2024 of Leiji Technology went to the site to explore the exhibition and made a follow-up report on the whole process, so please pay attention.

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.;
  • Cockpit control module is equipped with Qualcomm 8155/8295 chip, 7nm process, 105K DMIPS computing power, and supports 3D character image rendering, face recognition, AR-HUD and other functions.;
  • The intelligent driving domain control module is equipped with Huawei Shengteng 610 high-performance chip and 7nm process, which supports the expansion of computing power of 200~400TOPS. The image processing capacity of ISP can reach 2.4GPix/s, which can cope with complex road conditions such as high speed and cities.

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.

2) Software platform

  • On the application software level, integrate big data, cloud diagnosis, information security and other software systems to achieve functional integration;
  • Deploy different domain software in different cores-MCU core adopts CP Autosar, and deploy different domain electronic control software in multiple MCU cores respectively; The HPC core adopts Linux OS and AP Autosar middleware;
  • By deploying software in different domains in different cores, the integration between multiple domains is opened horizontally, and the communication between the underlying hardware, operating system (CP autosar, Linux OS), middleware (AP autosar), protocol stack and application software is opened vertically.
  • Support FOTA, planning some comfort functions will support SOA.

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.

Zeng Taiyuan ｜ ＂loong＂ jumped into the Oxford English Dictionary.

Perhaps it is purely coincidental, but I believe it is intentional, deliberate and then move. In January 2024, on the eve of year of the loong, the Oxford English Dictionary (OED), a treasure house of English words, showed obvious movement, and turned its attention to China again after many years. The English word "loong" awoke from hibernation, opened his eyes and got up, ready to rise.
For the first time in history, Chinese dragon (loong) has been included in the brand English dictionary, and it is also OED, a recognized word authority in the English-speaking world. Chinese dragon has gone through lexicalization, from loose free combination to tight fixed collocation, and it has been loaded into dictionaries and become a justified lexical unit.
Bronze Dragon with Gold Core in Tang Dynasty Collected in Shaanxi History Museum
The voluminous OED published its first edition in 1928, positioning itself as "the most authoritative record of English language". The second edition was launched in 1989, with a total of 20 volumes. After that, three small volumes of Addendum Series of Oxford English Dictionary were published one after another, adding new words and meanings and revising existing contents. In 2000, OED integrated the second edition and the addendum series, and launched a paid online edition. Since then, OED has gone online and updated online every quarter, providing readers with some results of the third edition under editing.
OED was updated in the fourth quarter of 2023 and was not officially launched until January 2024. Among them, the new entry, Chinese dragon, is complete and comprehensive in content, including pronunciation, etymology, definition, documentary evidence (quotation, a written example with a source), cross reference (two words are complementary to each other), and the collection history of entries (time information shows that Chinese dragon was first published in December 2023). Prior to this, Chinese dragon was not included in the traditional brand dictionaries in the English-speaking world, and it was only mentioned in the definitions or examples of other terms at most.
Chinese dragon has two definitions in OED. The first one focuses on the physical entity, which refers to the image or statue of loong, and the second one focuses on the psychological projection, which refers to the animals in China mythology, covering the first definition. The following is the second definition of Chinese dragon, which is rich in content and three-dimensional:
A mythological creature or god associated with China,depicted in a variety of different animal forms but typically as a serpent with four limbs, And symbolizing wisdom, fortune, and power. Also: such a creative viewed as a personification of China or its former empire. (The god beast or spirit related to China is depicted as various animal forms, but it is basically a four-legged snake, symbolizing wisdom, fate and power. In addition, this beast is also regarded as the embodiment of China or the former empire)
OED’s documentary evidence shows that as early as 1754, the Chinese dragon group had appeared in the literature, and the Italian Letter written by Earl Irish aristocracy Orie. The latest documentary evidence is taken from the English Shanghai Daily on August 7, 2013:
The Chinese dragon is the greatest symbol of power and good fortune and no traditional festival is complete without an undetermined dragon dance. (loong is the grandest symbol of power and luck, and traditional festivals are complete only with undulating dragon dances.).
Before Chinese dragon became an independent word, the English translation of "dragon" was generally based on bare dragon. However, the traditional dragon in the West is the embodiment of evil, and its negative image is deeply rooted in people’s hearts. OED defines dragon as follows: "The mythical monster is a giant and terrible reptile, which often combines the body structure of snakes and crocodiles, with strong claws, like beasts or raptors, scales and wings, and can breathe fire sometimes."
Tang Chi Jin Zou Long Shaanxi History Museum
Loong looks like a dragon in the west, but there are key differences. That’s why English adds Chinese decoration in front of dragon to define and distinguish it. This Chinese dragon group appeared in written records in the middle of the 18th century, which indicated that English speakers at that time had realized the differences between loong and Western Dragons.
Loong is different from the Western Dragon, which is clearly reflected in the other two large authoritative dictionaries. One is Webster’s Third Edition New International English Dictionary published in 1961, which is a very large single-volume modern English dictionary published in the United States. Webster’s does not include Chinese dragon, but the definition of dragon gives loong a meaning, saying that it is a beneficial supernatural creation in Chinese mythology connected with rain and floods (a miraculous animal in China mythology, kind and generous, related to rain and floods).
The second is the New Oxford English Dictionary published in 1998, which is a large-scale single-volume modern English dictionary based on corpus, and has nothing to do with OED. Chinese dragon is not included in New Oxford either, but in the definition of dragon, loong’s goodness and auspiciousness are pointed out: in East Asia, the dragon is naturally a beneficial symbol of fertility, associated with water and the treasures. (In East Asia, dragons are mostly kind and generous, symbolizing wealth, which is related to water and heaven).
What these two large authoritative modern English dictionaries reveal is that even though loong has no other entries and is included separately, the semantics of dragon has been divided, which clearly shows that the dragon of western traditional culture is one piece, and the dragon of China traditional culture is another piece, which is related to each other but different. Dictionaries reflect the current situation of language, which means that such cognition has a sufficient mass base in the English world.
Some theorists believe that translating China’s dragon into English is a huge mistake, which must be dealt with seriously and corrected thoroughly. Now, it seems that it is no longer necessary. All kinds of evidence show that dragon can also refer to loong, which is different from the Western Dragon. If there are doubts about semantics and the context is ambiguous, it must be made clear that this dragon is loong, and it can be easily resolved by putting Chinese before Dragon. The literature also shows that Chinese dragon has been used for more than 200 years, and the relevant evidence of various corpora is overwhelming. On the eve of year of the loong, Jiachen was certified and included by OED, so it should be no problem to translate China dragon into Chinese dragon.
Of course, if the English of "long" wants to find another way, it is also a way worth trying with the help of the transliteration of Long. Dragon is one of the core features of Chinese culture, and the English translation of cultural characteristic words is always based on phonetics, which is universally applicable. Transliteration highlights the main body of culture and expresses cultural self-confidence. However, English as a non-native language is not our decision, and it is only effective if it is widely recognized by English speakers. This road is long.
