Interview with simon pegg: Weibo takes care of himself and wants to try his brain.

Special feature of 1905 film network After three years, Mission Impossible is back. The recipe is familiar, and Ethan Hunt’s old partners are still there.

 

Just last week, Tom Cruise, simon pegg, Henry Cavill and director Christopher Macaulay also made a special trip to Beijing to promote the film in China. Even the press conference was held in the ancestral temple.

 

Although it’s not the first time for several people to come to China, it’s still simon pegg who knows what Asian fans like.After teaching Tom Cruise to compare hearts in the Korean publicity campaign of Mission Impossible 6, several people did it again and again on the red carpet of the ancestral temple.


 

Speaking of this finger-to-heart gesture, simon pegg said,I learned it from fans at the Korean airport.. As a result, the activity of "learning now and selling now" immediately aroused Tom Cruise’s curiosity.

 

In addition to empathy, simon pegg’s Weibo is also quite skilled. See more Hollywood stars holding a piece of paper to verify their identity, and then give it to the staff to take care of; The Weibo painting style of "Simon Gathering" will be much more exotic. I promised to send nude photos after 1 million fans, and the result was my own model posing; There was also a brain cake on Halloween, and the result was screened by the pictures of pig brain flowers of fans.

 

When we asked Weibo about his cake, he said that he just wanted to show off the cake made by his sister, but China fans were so dismissive that they showed their real brains instead.Twitter gave him to the staff, and Weibo’s account was actually updated in person.. Although half of the replies were in Chinese that he didn’t understand, he also had a lot of fun.

 

The audience loves Simon so much. Apart from playing a geek-like assistant in Hollywood movies, it is natural that he collaborated with edgar wright and Nick Frost in the trilogy "Much ado about nothing" and "Blood and Ice Cream". Although edgar wright, who is struggling in Hollywood, has been waiting for cooperation with Simon again, it was Nick Frost who first got together with Simon in the movie.

 

Although Simon and Nick are only cameos in this film, Slaughterhouse Guidelines is the first work of their new production company. Will there be some tribute to my old friend Edgar in the movie? When we asked Simon, he smiled and said that if there was one, it was the director’s intention.

 

British "gay friends" who are also going to Hollywood, when Edgar left to start shooting, simon pegg shuttled through various series of movies that he loved quarterly as a child. After starring in Star Wars, writing a script for Star Trek and collaborating with Spielberg, is there any director simon pegg wants to collaborate with? The answer he gave was unexpected:

 

What director does simon pegg want to cooperate with most now?Cohen brothersAnd the one taken last yearPaul Thomas Anderson. In his view, the two directors have changeable styles and can grasp comedy, thriller and plot at the same time.

 

1905 movie network:You have collaborated with Tom Cruise on three "Mission Impossible" films before, and this is the second collaboration with director Christopher Macaulay. Should it be easy this time?

Simon pegg:I think every time you return to a story you are familiar with, it’s like going home, or getting used to the way things go. With the success of this series, I really feel relaxed. But never lose the challenge. You know the creators will always let you out of your comfort zone. You will learn new things and have many new experiences. I have been looking for the excitement of this series.

 

1905 movie network:At the end of the film, you and Rebecca Ferguson have a fierce confrontation with sean harris, and your character Bangui is even killed. Have you talked to the director about the ending of Bangui?

Simon pegg:Every time we talk about stories before shooting, we will discuss who will live to the end. And this one does have many roles that didn’t last. But in the end, the director thought it would be too much to let Benji die. Because Bangui is a popular character.This is a role that the audience will feel empathy for, because Bangui is similar to them in some places. He is very ordinary. I think killing him is like killing the audience.. But who knows next time?

 

1905 movie network:In this film, we see the growth of Bangui, who has more and more field missions. So in the process of shooting, do you have any stunts that you choose to complete under the impetus of Tom Cruise or the director?

Simon pegg:No, I am happy to do these crazy things. Although I can’t do what Tom did, I will try if there is any chance of stunt performance.For example, the underwater scene, although short, was really played by me.


 

1905 movie network:This should be the most stunt you’ve performed in this series?

Simon pegg:Quite a few. But I also have a scene in "Mysterious Country" where I sit in a car and get chased by many cars. That’s exciting, too I also have a fighting scene in that movie. However, the helicopter and skydiving in this part are left to Tom.

 

1905 movie network:Besides being an actor, you are also a screenwriter. Will you change part of the script or discuss with the director about the increase or decrease of the plot?

Simon pegg:A few lines, mainly Bangui-style lines. I can’t make any changes directly with Chris. Because he is also a good screenwriter. He has great control over the plot and characters, and he is a master. But Bangui itself still has some room to make some language adjustments, and Chris is glad that I will make some changes in this regard.

 

1905 movie network:It can be said that you have cooperated with all your favorite directors. Will there be directors who want to cooperate in the future?

Simon pegg:I want to cooperate with the Cohen brothers. I also want to cooperate with paul thomas anderson.. They are all good directors. The Cohen brothers make movies together, and Paul, and I like all their movies very much. I think the movies they make combine comedy, thriller and plot very well. The style of the film is changeable. They made my favorite movie, so I really want to cooperate with them.

 

1905 movie network:We are all concerned about your work "Slaughterhouse Guidelines" which was reunited with nick frost, and it is also the first work of your production company. Will there be a tribute to the previous trilogy of blood and ice cream?

Simon pegg:The director is Crispin Mills and the screenwriter is Henry Fitzbert. I think this is their movie. I joined as a producer, working with two companies, Promoting Global Media and Sony.So we were co-producers, and we played a small role. The protagonist of the film is a young man. If there is a tribute, it is Crispin’s behavior. (Laughter)

 

1905 movie network:You have many fans on Weibo. Do you remember the picture of the brain cake sent about two years ago? Have you tried brain flower since then?

Simon pegg:I remember that one because the cake is in the shape of a brain. But everyone seems to disagree and think, oh, it’s just a brain. We eat it anyway. I haven’t tried it yet, but I will try it.

 

1905 movie network:The picture of you teaching Tom Cruise to compare feelings is also circulating on the Internet. Where did you learn it?

Simon pegg:I think I learned it that day. I learned it at the airport. I have many lovely Korean fans. They came to meet me at the airport and taught me this way of comparing my heart with my fingers. I started doing it on stage. Tom came to ask, what is this? I said, this is empathy. Tom began to learn. I’m glad to teach Tom a little trick.

 

1905 movie network:You learn these popular things really quickly, and you can use all kinds of filters.

Simon pegg:Yes I sent it to Weibo myself. I basically don’t tweet myself because I want to stay away from Twitter. butWeibo is a very interesting place. Although I can’t understand half of the reply, because it is in Chinese. But I think it’s really great.


1905 movie network:Back to Mission: Impossible-Fallout, the director commented that’ the accident is an opportunity to surpass. Do you think you have encountered a similar situation?

Simon pegg:I think it should be the helicopter scene. Because it’s amazing. We’ve seen it in other movies, and we’ve seen it in other spy movies. Because that’s what spy movies are all about. There are trips, exotic scenery, various variables, and the pursuit of various means of transportation.. But this time Chris interpreted it in a new way, which I think is very powerful.


I promised her that I would eat braised pork every day after the epidemic.

Editor’s note:

On April 7, 2022, Pudong Hospital was transformed into a designated hospital in COVID-19 to treat COVID-19-positive hemodialysis patients. Dr. huimin jin, doctoral supervisor of Fudan University and director of the Department of Nephrology of Pudong Hospital, and his colleagues stuck to their posts in a special period and fought day and night to save many hemodialysis patients.

The following is his medical diary:

April 26, 2022

The 20th day of the designated hospital.

How time flies! In a blink of an eye, I have been in charge of hemodialysis patients in designated hospitals for 20 days. Although some have returned to the community after discharge, there are still patients who are constantly new and seriously ill. Every morning, like a war, it is necessary to focus on the seriously ill patients and decide which patients need bedside dialysis, and the patients whose condition is relatively stable will go to the hemodialysis room for dialysis. The doctor’s advice for hemodialysis should be made on the same day, and the corresponding ward should be informed. Checking nucleic acid is also an important task, which is the standard to judge whether a patient can leave the hospital. The first batch of medical staff in the hospital have changed rooms, but all our nephrologists are in the first batch, and there are no redundant doctors to change with us, so we must continue to work.

Originally, the work has been on the right track, and everyone is proceeding in an orderly way. At the same time, we hope to treat more COVID-19-positive hemodialysis patients. However, this calm mood was interrupted by a sudden notice yesterday afternoon. The hospital asked all positive patients in our hospital to be transferred to other designated hospitals the next day (today) in order to make room for bleeding and provide treatment for more negative hemodialysis patients. So, several doctors filled in all the information of patients to be transferred, wrote the transfer summary and transfer receipt …… and arranged dialysis for hemodialysis patients this morning (Tuesday).

Dr Yang Xiuhong.

After Dr. Yang took over from the night shift, he contacted each ward about dialysis this morning, so as to ensure that after dialysis, the burden of doctors in the next receiving hospital will not be increased, and it is hoped that there will be no more dialysis for a long time and emergency hemodialysis will be needed in the new hospital. Today, all doctors and hemodialysis nurses arrived at their posts during the day to arrange dialysis and transfer to other hospitals. The head nurse of nephrology repeatedly checks the patient information to avoid information errors or missing any hemodialysis patients, and at the same time, she personally checks in the ward to do a good job in the ideological work of each patient’s cooperation with the transfer. Dr. Bao and Dr. Zhang are responsible for the guarantee of bus transshipment, and personally pay full armed to accompany patients to the corresponding hospitals.

The work in designated hospitals should have ended here. According to the regulations, it should be 7+7 (isolation for 7 days+isolation at home for 7 days), but our team can only rest for one week, and other COVID-19-negative patients are waiting for us. I would like to thank all the friends of our hemodialysis team here. Without your support and dedication, everything would be impossible, and it is still vivid to dispatch emergency bedside dialysis every night. ……

List of nine doctors: huimin jin, Gu Huifang, Gu Yanhong, Zhou Dongchi, Zhan Xiaoli, Fu Shunkun, Yang Xiuhong, Bao Wenjing and Zhang Hua.

Thirteen nurses in hemodialysis room: Shen Li, Li Dongfeng, Guo Xiaocui, Huang Minmin, Huang Shidan, Qian Jiayan, Wu Huimin, Gu Xuehua, Zhu Danhong, Zhang Wei, Gu Xiaoli, Chen Xiaoqing and Cao Honghui. Li Li and Lai Bihong, head nurses of nephrology and hemodialysis room. Finally, I would also like to thank Shen Li, the benchmark nurse of hemodialysis, for building a WeChat group for our team-Left-behind Hemodialysis Desperate Saburo. In this group, many important rescues are issued and executed from the group. It may not be appropriate to call Saburo Desperate. There are only three male doctors, and the other doctors and nurses are all women, but it doesn’t matter. Everyone just works hard or Saburo Desperately.

After nearly a month’s treatment of hemodialysis patients in a closed community and 20 days’ experience in a designated hospital, the biggest change is that the hair of our female doctors and nurses in charge of hemodialysis is dry and forked, and half of my own white hair is now completely white. This is the biggest change during the epidemic, and this change will continue. I don’t know when it will end. Let’s experience the feeling of home. Tomorrow will be a 5+2 rest. Tomorrow is also our doctor Yang’s birthday. Her greatest wish is to have a braised pork, but such a simple wish is hard to come true, because we can’t go home. I have promised her that I can let her eat braised pork every day after the epidemic is over.

April 17, 2022

The 11th day of the designated hospital.

Seven o’clock. The epidemic in Shanghai began in mid-March, and it has been a month now.

Our young doctors have experienced too many things that have never been touched before, and they all feel physically and mentally exhausted, and they feel like they are collapsing at any time.

Dr. Zhang Hua is one of the young doctors. Today, I ended my diary with Dr. Zhang Hua’s essay:

When I left home, my little grandpa couldn’t shout clearly. Now he can recognize Arabic numerals, and he has been fighting the epidemic for 42 days in the blink of an eye. I entered the cabin at 2 am last night, and more than eight hours have passed since I came out. I have always felt that some patients are pitiful and always want to be perfect, but there are too many poor people in the world. Classmates say you always pity others. Does anyone pity you? Yes, we are also the poorest people. We always want to protect others as much as possible, but who will protect us? From the first closed-loop week, sleeping in hospital beds and camp beds to living without a fixed place, we have been persisting and persisting.

One day it happened that I was on duty 24 hours a day. At last, after everyone left, the ward was empty, except for the noisy voice of the construction team. I felt scared alone in the duty room. Our patients on the 13th floor temporarily merged into 15A, but the doctor on duty did not have a foothold in 15A, so I went to the 13B duty room for one night.

Later, I heard that the hospital was going to become a control area. Area A was the remaining negative patients, and Area B was the patients from the control area. Later, the hospital arranged a hotel for us, and we finally ended the days of moving around. Slowly, the number of patients in the control area increased, and later, other hospitals transferred a group of patients to our hospital overnight, and some medical staff fell down because of their busy work.

Doctor’s photo (2)

This period of time is the most difficult time in our department. We have to take care of patients across several wards, and there are constant emergency consultations and hemodialysis patients in the middle of the night. The most impressive time for me was that I invited 5-6 urgent consultations in the emergency room one night, which was equivalent to that I hardly slept in the middle of the night. In the most difficult time, only three doctors in our ward were on duty 24 hours a day. Later, there were more and more emergency cases and more and more serious cases. Dr. Fu is our big brother. He shoulders the burden of the control area and consultation. He takes care of all the serious first-aid patients in advance. We three little guys are in charge of the ward, and Director Jin takes the initiative to take the fourth shift of hemodialysis (equivalent to 24-hour round-the-clock rotation in the hemodialysis room).

Because recently, many people can’t get dialysis treatment in time because of closure, and some of them have not had dialysis for 5-6 days, and their lives will be in danger at any time. For them, Director Jin opened the fourth hemodialysis class without hesitation, so we maintained it for some time. Thank you, Brother Fu, for silently taking on so much for us, because he has to keep shuttling through the sealed control area, emergency room and fever clinic (some patients have no nucleic acid reports), and he can only bite the bullet to save his life. Our brother Fu finally fell down. Yes, this is our life. I hope that the epidemic will end as soon as possible, that we will return home as soon as possible, and that our son can recognize his mother … "

May 4, 2022:

Today is the first day of the change from positive to negative. After a short week’s rest, the original dialysis room was completely sterilized, and the first batch of patients were ushered in after many sampling inspections passed. Most of them are our old patients, and everyone is very happy to meet again. It is also orderly to enter the hemodialysis room in the morning, and most of them have 24-hour nucleic acid negative results. Individuals who do not have 24-hour nucleic acid also communicate with patients and their families, and immediately contact the neighborhood Committee to complete the nucleic acid test as soon as possible after returning.

Jin Yisheng examined the patient.

At 5: 30 in the evening, the third class of patients arrived and met another patient who needed temporary deep vein catheterization due to internal fistula occlusion. With the joint efforts of the Deputy Director of Vascular Surgery and Dr. Zhou of Nephrology Department, the catheter was successfully placed and dialysis began immediately. Today, three classes of dialysis, Nephrology dispatched nine doctors, cooperated together, and the division of labor was clear, and the dialysis of nearly 200 patients in three classes was completed in an orderly manner.

Today, the weather is fine, and the sun is shining brightly during the day, but our medical and service staff still need to put on white clothes, and they are already sweating before they work. The third nurse kept calling for heat after getting on the plane, but there was no way but to endure it. I hope these days will end as soon as possible.

The happiest thing today is that our doctor Fu has recovered. He is in the third shift today, and his spirit is very good. Together with him and Dr. Yang, I checked the patients in the third shift well. Dr. Fu particularly emphasized one patient. This patient is an old patient in our center. Last night, he went to Chuansha People’s Hospital because of chest pain. In the emergency department, he checked his electrocardiogram and myocardial enzymes, all of which were abnormal, but the patient refused to be hospitalized. Dialysis happened to consult Dr. Xiao Fu again this evening. Dr. Xiao Fu patiently and carefully looked at all the tests of the patient and thought that acute myocardial infarction could not be ruled out. He suggested that the patient go to Chuansha Hospital immediately after dialysis tonight, because the emergency room of Pudong Hospital was temporarily closed, and the hospital was a designated COVID-19 positive hospital. Everything is for the safety of patients, and Dr. Xiao Fu has brought the concept of our department to the extreme. This is our work style, and we praise such doctors.

 

Heterogeneous in the transmission! Analysis of Toyota E-CVT transmission

  [Pacific Auto Network Technology Channel]What is it? Can realize the automobileSpeed change, torque change, direction change and on-off powerThe device is the transmission. The first car in the world was born in 1886, and the first transmission appeared soon after. It can be said that the development of transmission and automobile are synchronous. At first glance, E-, maybe everyone will naturally think of CVT, that is, CVT. Functionally speaking, E-CVT does have the function of stepless speed change, but structurally speaking, the difference between them is too great. It can even be said that there are two types of transmissions, one is E-CVT and the other is other transmissions.

● Introduction of E-CVT

  At the beginning, we mentioned that E-CVT is not a simple "electronically controlled continuously variable transmission", so of course it is not circulated on the Internet. It is an electronic version of CVT. Toyota’s official definition is "power distributor", because it does not have complex mechanisms such as traditional gearbox system or gear shaft set, and it is a power distribution mechanism specially prepared for hybrid vehicles. Therefore, there has always been a debate: is E-CVT a transmission?

 

For more articles about gearbox classification, please click the following figure to browse:

Inner chain 1

 

  Whether it is a transmission or not, we will discuss it later. What we can see is that the THS( Hybrid System) is becoming more and more mature from 200h to the later hybrid version. As a key component of the whole system, E-CVT undoubtedly plays a vital role. 

Ingenious conception and good economy! Full analysis of ECVT transmission

E-CVT structure

  If you look at it from the perspective of traditional transmission, the structure of E-CVTIt’s really, really simple. Many times, the more perfect things are, the simpler they are. I think this must be the truth. As a masterpiece of hybrid cars, Prius has been carrying the core hybrid technology, so the next analysis takes Toyota Prius as an example.

Ingenious conception and good economy! Full analysis of ECVT transmission

  The structure of E-CVT is very simple, only made up ofExternal gear ring(The outer gear ring here connects the No.2 motor and the output shaft at the same time) andplanetary carrier(connection) andSun gear(connected to No.1 motor), that is, the power transmission flow is:No.2 motor — External gear ring — output shaftAt the same time, due to the existence of planetary gear sets, there are also:Engine — Planetary group — External gear ring — output shaft. The following physical picture was taken from a foreign video.

Ingenious conception and good economy! Full analysis of ECVT transmission

  If you look closely, you can’t help wondering: Isn’t this the structure? Yes, E-CVT is made up of a planetary gear set reduction mechanism (The red box in the picture above.)。 There is no chain or steel belt in CVT, let alone the torque converter in AT or the double clutch in DCT. So, the problem is coming. . . Ahem. Can an E-CVT with such a simple structure really achieve stepless speed change? The answer is of course!

E-CVT principle

Overview:

  In fact, E-CVT is not very complicated only from the perspective of mechanical motion principle. How complicated can the motion of a planetary gear set be? What is complicated is its electronic control unit, that is, the logical principle of electromechanical cooperation. Before introducing the working principle, briefly list some noun notes that will be used below:

PCU:Power Control Unit (Power control unit) This is an essential part of a hybrid car, which contains a voltage converter and an inverter, and can adjust the output voltage of the battery pack. For example, high voltage (about 600V) must be used to supply power to the motor, and the voltage of the battery pack is up to about 200V due to the size limitation, so the transformer is essential. butThe function of inverter is to change DC to AC or vice versa.Because the high-voltage AC motor has the advantages of small size, high efficiency and large size, and the battery pack emits direct current, an inverter is necessary between the motor and the battery pack.

MG2:Namely motor generator 2, andExternal gear ringConnect.

  The engine of Prius is Atkinson engine, which is characterized by good intermediate speed performance, insufficient high and low speed performance and high energy utilization rate;

  To facilitate understanding, put a simplified E-CVT structure diagram:

Ingenious conception and good economy! Full analysis of ECVT transmission

  Next is the power distribution diagram.

Ingenious conception and good economy! Full analysis of ECVT transmission

  First of all, we need to be clear about a concept:Power is the product of combination with rotational speed.(power = torque × rotational speed),

  Then because there are four that canFree revolutionPlanetary gear, it can be imagined that when the gear ring is fixed (that is, the wheel is fixed), the sun gear (MG1) can only drive the planetary gear seat (that is, the engine) to rotate (that is, start the engine process) when the planetary gear rotates;

  With the rotation of planetary gears, when the ring gear (MG2) rotates forward, the sun gear (MG1) can also rotate backward. Conversely, when the ring gear (MG2) rotates reversely, the sun gear (MG1) can rotate forward again.

  For example, when the outer ring gear and the sun gear rotate in the same direction, the planetary gears can not rotate, but only revolve, thus driving the gasoline engine to rotate. When the planetary gear seat does not rotate, the ring gear and the sun gear can still rotate freely. It is precisely because of this ingenious characteristic of the planetary gear set,Only when the engine, wheels and motor are connected together can they run without interfering with each other.Therefore, the clutch structure is omitted.

Ingenious conception and good economy! Full analysis of ECVT transmission

  S=C×3.6-R×2.6

  In the formula, s = sun = sun gear, c = carrier = line constellation, and r = ring = outer gear ring.

  In addition, since the diameters and teeth numbers of the external gear, the sun gear and the planetary gear have been fixed, it can also be obtained according to the formula on the drawing:When the planetary constellation rotates in the middle, the torque ratio allocated to the outer ring gear and the sun gear is certain.. The specific value is about72%Allocated to the external gear (actually 2.6÷3.6),28%Allocated to the sun gear (1-72%). As long as the engine rotates to work, it will not change this basic fact.

Ingenious conception and good economy! Full analysis of ECVT transmission

  Then we all know that under a series of different working conditions, the requirements for torque are greatly changed. Traditional power vehicles need a transmission to adjust the output power of the engine. However, in this specific structure of E-CVT, because there are two motors, under different working conditions,According to the above formula. As long as the different rotational speeds of these two motors are controlled, the engine power obtained on the outer gear ring can be changed infinitely, so that the automobile can achieve stepless speed change.

  As for how the PCU of Prius can control the fuel supply of the engine and the voltage, phase and positive and negative on-off of the two motors in real time according to the running conditions of the car. The control logic involved and the data collection and processing procedures of many sensors are too complicated to be described here. Understand that E-CVT can realize stepless speed change.

Detailed explanation of working conditions

  The following analyzes the speed change process of E- one by one from various operating conditions:

I. Idle running (hot car)

  After the start command is issued, it starts (rotates forward) in an instant and drives the start. The whole process is extremely fast and smooth.

Ingenious conception and good economy! Full analysis of ECVT transmission

  After the engine is started, it runs at idle speed, and the gasoline engine drives the planetary constellation to rotate forward. Because the wheel (outer ring gear) does not rotate, the forward rotation of the planetary gear set (engine) will drive the sun gear (MG1) to rotate forward through the planetary gears. MG1 no longer receives power from the battery pack, but becomes a generator.Emit alternating current, through the inverter and voltage converter in PCU, it becomes low-voltage DC and charges the battery pack. In short, at idle speed,The whole engine is used to charge the battery pack..

Ingenious conception and good economy! Full analysis of ECVT transmission

Second, start

  After the start signal is sent, a small amount of power will be connected to the No.2 motor, and MG2 will start to rotate. Drive the wheel (outer gear ring) to start forward rotation, and the car moves slowly. When you press the accelerator pedal slightly hard, the No.2 motor will get more power and the Prius will accelerate. Because the power of No.2 motor is very high (50KW), the low speed is also very high. Under the control of PCU, the acceleration of the car is very soft.Even by MG2 aloneYou can accelerate the Prius to a considerable speed! This starting process gives full play to MG2.Low speed and high torsionTo make up for the embarrassing situation of insufficient low-speed torque of the engine.

Ingenious conception and good economy! Full analysis of ECVT transmission

  It is worth noting that if the engine is not working at this time (starting in pure electric mode), with the increase of the rotational speed of MG2, the rotational speed of MG1 will also increase rapidly. Because the speed of MG1 has an upper limit, when it reaches the upper limit, the engine is forced to start to intervene. There is a critical speed at this time. Although this speed is fixed, it is certain that the greater the intensity of stepping on the accelerator at the start, the earlier the gasoline engine will intervene (actively intervene). If you step on the accelerator all at once, the gasoline will ignite immediately.

  In most cases, MG2 can smoothly accelerate the Prius to a good speed, but in some cases, there will be a phenomenon of insufficient power. This is what the engine will pass after intervention.Driving MG1 to generate electricity for MG2.andDirectly drive the external gear to rotate to push the wheel.Two ways to output power, it is worth mentioning that these two ways can exist at the same time. As for the proportion of each other, it depends on many factors.

Third, small load acceleration

  When accelerating under light load, the wheels are mainly driven by MG2. With the speed of MG2 increasing, the speed of reverse rotation of the four planetary gears gradually decreases. When the speed of the gear ring is the same as that of the planetary constellation (engine), the rotation of the planetary gears stops, leaving only revolution. At this time, the planetary constellation (engine) pushes the gear ring (wheel) and sun gear (No.1 motor) through the four planetary gears that are no longer rotating, and the three speeds are consistent. MG1 continues to supply power to MG2 and charges the power battery through PCU. Thereafter, the speed of MG2 continues to increase until the vehicle reaches the target speed. At this time, the sun gear rotation speed is less than the rotation speed of the constellation.

Fourth, heavy load acceleration

  In the face of heavy load acceleration (such as load starting), the power of MG2 can’t keep up.Engine speed increaseEntering its economic operation range, the power of the engine is greatly improved. Because the torque increase of the engine further drives MG1 to generate electricity and the power obtained by the outer ring gear increases, at the same time, the battery pack will also supply power to MG2. Thanks to this, MG2 enters the "full firepower" mode.

Fourth, driving at a constant speed

  Driving at a constant speed occurs after the acceleration is completed. At this time, the Prius only needs to overcome all kinds of resistance, and the demand for power and torque is greatly reduced. After the throttle is relaxed, the speed of the gasoline engine decreases, and the speed of the gear ring (wheel) is higher than that of the planetary carrier (gasoline engine). At this time, the four planetary gears began to rotate forward. This forward rotation will drive the sun gear (MG1) to reverse.

  There is something special here, as we learned from the previous article. When the power from the engine is transmitted to the outer ring gear and the sun gear through the planet carrier, the rotational speeds of the outer ring gear and the sun gear will satisfy the following formula.

  S=C×3.6-R×2.6

  When the rotating speed of the outer gear ring is higher than that of the planetary carrier, that is, when R>C, it is obvious that S < 0, that is, it is reversed. However, if the reverse rotation of sun gear at this time is idling (without any resistance), it will rotate so fast that all the power from the engine will be absorbed by MG1 and the external gear ring cannot be driven (because it is obviously much easier to drive sun gear than to drive the external gear ring). Therefore, MG1 will need to work in the motor mode here, so that the planet carrier can’t drive the sun gear to fly at high speed and waste the power of the engine.

  But wouldn’t that be a waste of electricity? Therefore, in general, when cruising at high speed, MG2 becomes a generator to maintain the rotation of MG1.

  In fact, during the whole driving process of Prius, the state of acceleration and uniform driving is constantly switching. The phase of voltage and current will be adjusted by PCU according to various operation actions such as stepping on the accelerator and releasing the accelerator, and various driving conditions of the car, and the output power and rotating direction of the motor will be changed instantly, and the functions of the two motors will be switched.

Fifth, slow down

  In fact, the deceleration is relatively simple, with the engine turned off and the MG1 idling. MG2 is driven by the wheel and becomes a generator to absorb the deceleration energy of the wheel. And charge the battery pack.

Sixth, reverse the car

  Thanks to the large torque of MG2, the torque MG2 required by the Prius when reversing can be easily provided. The battery pack supplies power to MG2, which drives the external gear ring to reverse, and the vehicle finishes reversing.

Ingenious conception and good economy! Full analysis of ECVT transmission

  In the whole driving process of Prius, we can see that it is actually a process in which two motors and engines cooperate with each other to perfectly perform linear output under strict electromechanical conversion logic control. The basis of this perfect cooperation is the special structure of E-CVT. Because power = torque × rotational speed, the planetary gear set structure with proportionally distributed torque and infinitely distributed rotational speed enables the power of the engine to be infinitely distributed to the outer gear ring (i.e. wheels) at any time and place, thus completing all functions of the ordinary stepping gearbox!

  The following table shows the running state of each gear of E-CVT during the whole process:

  You can also refer to the following video to improve your understanding of the operating relationship between planetary gears, sun gears and external gear rings.

Prospect of E-CVT

  The appearance of gearbox was born in order to meet the different power requirements under various complex working conditions. Before it appeared, drivers needed to judge the road conditions and car conditions themselves to shift up and down in time. The advantage of this method is a strong sense of driving operation. After all, experienced drivers know what kind of power the car needs better than ECU. In addition, the advantages of simple structure, easy maintenance and small size also make the car with manual transmission have a large number of fans no matter where it is suitable.

  The appearance of automatic gearbox is actually very early, but the real large-scale application was in the 1980 s, and it was also a free ride with the rapid development of electronic technology. Because automatic transmission is not difficult, it is difficult to change the speed more accurately. In the mechanical age, technology is obviously difficult to achieve, but nowadays, more and more intelligent ECU makes automatic transmission more and more able to understand your driving intention. But even so, the automatic gearbox still has defects:There is shift clearance.Even DCT can’t realize the real "stepless speed change".

  As for the protagonist E-CVT in this paper, it can be said that it has reached the peak of the integration of electromechanical technology in the gearbox field. First of all, its logic control system is very complicated. In addition, it can effectively make up for the short board (low transmission power) of the traditional stepless gearbox, which integratesHigh power, quick response, stepless speed change and extremely high transmission efficiency.And other advantages in one. But it also has disadvantages:The support system is too complicated.We know that once any system is too complicated, the probability of problems will increase exponentially.

summary

  Let’s make a simple summary of E-CVT:

1. Very smooth, extremely smooth

2, the transmission efficiency is high

3, simple structure and small volume

  Let’s go back to the question at the beginning of the article about whether E-CVT is right or not. Let’s put it this way: If other power sources were not needed to cooperate with it, I’m afraid E-CVT technology would have unified the gearbox field long ago. It is precisely because of this "fatal" defect that it is simply tailored for hybrid models. Writing this analysis is not entirely for the sake of popular science, but I hope that everyone can learn more about this somewhat heterogeneous and unknown transmission structure and its thinking. Because I firmly believe that in the future when fossil energy is exhausted, E-CVT will finally shine!

Put a "price" in the summer! Kia EV5 offers a comprehensive discount of 50,000 yuan in a limited time. Can the sales volume increase again?

It’s July, which is the midsummer season when walking on the street will melt, and it’s also the time when the automobile industry "puts a big price" in summer. Since entering the new energy era, the market share of joint venture car companies has gradually decreased, especially Korean cars, and the brand Kia of yueda seems to have gradually faded out of public view.

Recently, however, Kia coincided with its 80th anniversary, which directly brought a wave of embarrassment to consumers. The comprehensive discount of Kia EV5 reached 50,000 yuan, including 10,000 yuan for car trade-in. In fact, it’s not just KIA EV5. As of July 31st this year, consumers can enjoy different degrees of limited-time preferential policies when purchasing models such as Lion Platinum Tuojie, Satus, New K3, Sonay, Jiahua, K5 and EV6, and the comprehensive benefits can reach 73,000 yuan.

At the same time, on July 5th, Kia of yueda also announced the results of the first half of this year, and the sales volume also increased significantly. Combined with this month’s preferential policies, it seems that Kia is ready to be overjoyed and regain its market share in the era of fuel vehicles.

Yueda Kia’s sales increased significantly in the first half of the year.

As soon as the bell rang in July, many car companies produced their own report cards, and the overall sales volume of the whole market showed a thriving scene. Although KIA of yueda only released its sales volume today, although it arrived late, from the data point of view, KIA of yueda’s sales volume in the first half of the year was still remarkable.

According to official data of Kia of yueda, its sales volume in June 2024 reached 20,700 vehicles, up 32.7% year-on-year. It is worth mentioning that this is the first time since November 2020 that its monthly sales volume once again exceeded 20,000 vehicles. From January to June this year, the cumulative sales volume of Kia in yueda reached 109,600 vehicles, up 73.1% year-on-year, and the increase was really gratifying.

In fact, the bumper sales of Kia in yueda can not be separated from its business strategy of "developing both oil and electricity" and building a diversified product matrix. For example, the Kia EV5, specially launched to celebrate the 80th anniversary of the founding of Kia in yueda, is the first heavy strategic vehicle launched in China and sold worldwide, and it is also a masterpiece under the concept of "in China, for China".

Product strength of KIA EV5

Kia EV5 positioning compact SUV is a pure electric vehicle with an official guide price of 149,800-225,800, but now there is a comprehensive discount of 50,000. Its overall dimensions are 4615mm*1875mm*1715mm, and its wheelbase is 2750mm. The overall design of EV5 is individual and avant-garde, and the lines are quite smooth. Generally speaking, it is quite satisfactory, and there is no bright spot.

The interior of KIA EV5 is simple and full of science and technology, with a 12.3-inch central control panel and a 12.3-inch full LCD instrument panel in the middle, which supports CarPlay, CarLife and OTA upgrades. Seats are different for each model. For example, KIA EV5 530 Light is equipped with fabric seats, but 720 Land is made of imitation leather.

If the power lasts, the KIA EV5 two-wheel drive version adopts the front-drive drive mode, and the chassis suspension is McPherson independent suspension+five-link independent suspension. Its maximum power is 160kW, the maximum torque is 310N·m, the maximum speed is 185km/h, and the CLTC has a pure battery life of 530km and 720km. It is equipped with lithium iron carbonate batteries.

Generally speaking, the overall strength of KIA EV5 is good.

Qingdong review

Although joint venture car companies are a little behind in the new energy era, they are also catching up quickly, and yueda Kia is obviously no exception. So will the discounted KIA EV5 be your dish? Welcome to leave a message in the comments section.

BMW’s Pure Electric Ambition: Replicating the Success of 5 Series with i5

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

BMW’s best-selling luxury car, the 5 Series, has finally been replaced, and this time BMW rarely chose to launch both oil and electricity at the same time.

On November 17th, BMW’s eighth generation BMW 5 Series was officially unveiled at Guangzhou Auto Show, including the world’s first BMW 5 Series long wheelbase version and pure electric model i5.

The 5 Series is one of the few luxury cars in the global market with a production capacity of more than 10 million vehicles, and has long held the top position in the luxury car market in China.

Since entering the China market, the sales volume of the 5 Series has exceeded 2 million, and the seventh-generation 5 Series has sold 530,000 vehicles in the past three years.

Gao Xiang, President and CEO of BMW Group Greater China, praised the BMW 5 Series as "the most successful model of BMW Group in China" in Chinese at the Guangzhou Auto Show.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

Leifeng. com’s "New Smart Drive" understands that BMW attaches great importance to the release of the new 5 Series this time, because it is not only related to BMW’s re-declaration of its market position in domestic medium and large luxury cars, but also the key battle for BMW to define pure electric luxury cars.

How do traditional luxury brands, led by BMW, choose between "replacement" products?

Family-style design is not a simple doll, but a "fine decoration" on the premise of retaining recognizable elements.

On the eighth generation BMW 5 Series, you can see BMW’s most recognizable kidney grille, angel eye headlights and Hough’s corner.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

However, the kidney grille on the front face of BMW’s new 5 Series is wider and almost vertical than the previous generation, and the design of angel eye headlights is also simpler. At the corner of Huo’s corner, BMW also designed a bright logo with the number "5", which will also produce a blue breathing effect when charging the pure electric model i5.

In terms of body size, the eighth generation BMW 5 Series is divided into standard wheelbase version and long wheelbase version. Among them, the long-wheelbase version has a car length of 5175mm and a wheelbase of 3105mm, which is the ceiling of similar models.

In terms of interior, BMW has delegated many configurations unique to the flagship 7 Series to the 5 Series, such as the embracing interactive light strip in the car, the two-row suspended giant screen and the crystal-textured components.

When domestic car companies roll refrigerators, color TVs and big sofas, the domestic long-wheelbase version of the new 5 Series directly upgraded the "color TV" to a "cinema", equipped with a 31-inch, 8K resolution floating giant screen of the same model as the 7 Series.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

It is worth mentioning that this configuration of suspended giant screen was specially customized by BMW for users in China, and it was not installed on the overseas version of the 5 Series.

In terms of intelligence, BBA was often complained by consumers that its ability was far less than that of domestic independent brands. However, this time BMW officially got on the L2+ intelligent driver assistance system on the new 5 Series, and introduced an automatic lane change function with line-of-sight confirmation.

This function is based on capturing the driver’s eyes and head movements. When the lane change conditions are met, the driver only needs to look at the left/right rearview mirror to realize the lane change in the corresponding direction.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

Of course, there are restrictions on driving range and speed, and the restrictions must be met on high-speed and closed roads, and the driving speed is 60 km/h and 180 km/h.

BMW team members told Leifeng. com’s "New Smart Driving" that the styles of intelligent assisted driving systems of different car companies may be different, some emphasizing convenience and some emphasizing safety. In contrast, BMW’s style is really conservative, because in their eyes, "safety" has a higher priority.

It is reported that BMW China’s R&D team is carrying out localization research and development of L3-class autonomous driving, and the new 5-Series long wheelbase version actually has L3 capability in technology.

In addition to the improvement in appearance, interior and intelligence, the biggest highlight of this generation of 5 Series is the introduction of both fuel and pure electric vehicles in the China market.

The fuel version of BMW 5 Series is equipped with an in-line four-cylinder turbocharged engine and adopts 48V light mixing technology, with a maximum power of 190 kW and a peak torque of 400 Nm, which makes this model have a stronger and more efficient power output.

Pure electric vehicle-BMW i5 adopts the fifth-generation BMW eDrive electric drive technology and BMW’s latest charging technology, and its long wheelbase version has a cruising range of more than 700 kilometers.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

In terms of handling experience, speeding up faster than fuel vehicles has always been one of the skills of electric vehicles.

In order to enable drivers to have the driving experience of a sports car while driving a medium and large car, BMW introduced the M model (the highest-end performance model in BMW) into the pure electric i5 for the first time. Press the Sport Boost button and step on the accelerator, and the output torque of the dual motors can reach 820 Nm, achieving zero acceleration in 3.8 seconds.

Although this model is not the best in the industry, it is the first among the products sold by BMW.

Abandoning fuel vehicles and all in pure electricity is not only a matter of cutting off the left hand or the right hand, whether for high-end brands like BMW and Mercedes-Benz or for global brands like Volkswagen and Toyota.

Most car companies choose both fuel and pure electric vehicles, trying to use this product matrix to smoothly transition from the fuel era to the pure electric era.

Of the BBA three, BMW was the first to choose "self-revolution" and made a military order. In 2021, BMW set a more detailed goal of turning to the pure electric market:

In 2023, 12 pure electric vehicles will be provided in 90% market segments.

It is estimated that by 2025, the annual sales of pure electric vehicles of the Group will be more than 10 times that of 2020.

It is estimated that the delivery of the world’s 2 millionth pure electric vehicle will be completed by the end of 2025.

At the earnings conference call in 2022, Qi Puce, chairman of BMW Group, once again stressed that in 2023, it will go all out to electrify, with the goal of increasing the sales of pure electric vehicles to 15% of the total sales of the Group.

How about BMW’s electric progress bar in China market?

In November, 2022, BMW launched five pure electric vehicles in China: innovative BMW i7, brand-new BMW i3, BMW i4, BMW iX and BMW iX3.

Let’s look at the sales data of a group of BMW pure electric vehicles in China market in 2022: the sales volume of pure electric vehicles in 2022 was 41,886, up 91.6% year-on-year. In the global market, the total sales volume of BMW in 2022 was about 2,399,900 units, of which the sales volume of pure electric vehicles reached about 215,700 units, up by 107.7% year-on-year.

In other words, the China market contributed about 20% of pure electricity sales.

Take BMW’s best-selling entry-level model 3 Series as an example. From January to September, 2023, the domestic sales volume of fuel-powered BMW 3 Series reached 110,258, while that of pure electric BMW i3 reached 35,693. The total sales volume of the two models was 145,951, with i3 accounting for about 24%.

With the success of the i3, it is not difficult to understand BMW’s ambition to make the i5 a benchmark model for all-electric luxury cars in the world.

A person close to BMW said that BMW regards the 3 Series, 7 Series and 5 Series as the main models in China market.

At least in the China market, the 5 Series has occupied the top spot of luxury cars with a price of 400,000-500,000 for a long time.

According to the data of the Association, in 2022, with the annual sales volume of 171,142, BMW 5 Series became the first in the domestic sales list of high-end cars with a price of over 300,000 yuan, and also the first in the domestic market segment of medium and large luxury cars with a price of over 300,000 yuan.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

In the fuel vehicle market, the direct competitors of BMW’s new 5 Series are Audi A6 Series and Mercedes-Benz E-Class. In the pure electric vehicle market, only the ET7 of Weilai can be compared with BMW’s new 5 Series.

Before BMW i5 entered the market, ET7 could be said to monopolize the market of more than 400,000 domestic medium and large electric cars.

The price of Weilai ET7 is 458-536,000 yuan. It comes standard with front and rear double motors, with a maximum total power of 653 horsepower and a maximum torque of 850 Nm. The fastest speed increase of zero hundred is only 3.8 seconds. In terms of intelligent hardware, ET7 adopts Qualcomm 8155 chip, and in terms of intelligent driving, it adopts four NVIDIA Orin X chips, finally reaching 1024TOPS.

At present, BMW has not announced the price range of the i5, and it will not have an official price until the model is officially launched in January 2024.

Therefore, at this stage, it is difficult to compare BMW i5 and Weilai ET7 who are more cost-effective, and who is the one who defines the pure electric luxury car.

From the details such as the new 5 Series with long wheelbase, the Chinese character "Five" designed on the front seat and the suspended giant screen specially introduced by BMW for China users, it can be seen that BMW has really made some efforts to compete for the pure tram market segment in China.

Not only that, BMW has also accelerated the laying of charging infrastructure like its own domestic brands.

BMW's Pure Electric Ambition: Replicating the Success of 5 Series with i5

In August 2023, BMW officially launched the super charging station project. High-power charging piles can support up to 600 kilowatts of charging power, and the network of super charging stations is open to all brands of electric vehicles. Within three months, the network of super charging stations will cover nine major cities including Guangzhou, and it is estimated that about 50 stations will be completed by the end of 2023.

By the end of October 2023, BMW had connected more than 580,000 public charging piles (including 320,000 DC charging piles) across the country, covering more than 320 cities.

Now everything is ready for BMW i5, except for its official listing.
