It seems that few people now dare to evaluate Tesla again, the four cars themselves, there is nothing to say, more importantly, @ Tesla legal department can not move to send a lawyer's letter, car reviewers are old rivers and lakes, in line with the principle that more is better than less, they also choose to remain silent. Not long ago, my friend (never seen, just on the Internet technical exchange) @ five thousand years of rabbits have also been prosecuted, how to see how to kill rabbits and monkeys means. But, among the monkeys, there will always be one who is not afraid.
Did the problem of brake failure be covered up by the Legal Department?
I saw the complaint against the rabbit for five thousand years, and it did contain his lack of caution and emotional rhetoric, but his analysis of the accident of the female owner of the Shanghai Auto Show was no problem, and it was quite professional.
According to the data given by Tesla, the driver began to step on the brake pedal 4.28 seconds before the collision, or crashed at a speed of 48.5Km per hour. In fact, you don't need to understand the car, just need to be able to drive to understand, the general performance of the vehicle, 100 km / h speed brake stop also takes 4 seconds! And the driver stepped on the brakes, indicating that he had a prejudgment of the road ahead. In this case, there is also a collision at high speed, if it is not a brake failure, it is only possible that the driver sees the vehicle in front of him, and the foot brake is not heavy, until the collision. This is clearly counterintuitive.
Subsequently, Tesla refused to provide complete data, and even the State Administration of Market Supervision ignored the following. This attitude can basically be judged, the complete EDR data is unfavorable to Tesla, according to the theory that the evidence can not be proved, it can already be judged that Tesla brake failure real hammer. Earlier, Han Chao, the owner of the rights defense who won the Tesla sales fraud, said that Tesla is a rogue, and I think this kind of behavior ......@ID Han Chao is right.
The failure of the brakes, the roof guard lady is not alone. Hainan, Tesla staff personally demonstrated that they could not stop, is this a real hammer? In the program of @City Private Car Xiaobei, Tesla staff personally admitted that it is a software problem that causes the brakes to harden, is this a real hammer?
In the complaint against the five-thousand-year-old rabbit, there is this sentence: "Tesla" brand car is an electric vehicle with a high reputation and good reputation around the world... I don't deny the high popularity, but the good reputation... Sales fraud, sentenced to one loss of three, as a fraudster, how good can the reputation be? Being named by CCTV and central media, listed in the "Annual Report on the Protection of China's Consumer Rights and Interests (2021)", and jointly interviewed by the Municipal Supervision Bureau, the Cyberspace Administration, the Ministry of Industrial Information, the Ministry of Communications and the Ministry of Emergency Management, I am afraid it is not a good reputation, right?
Even Musk, the owner of the company, openly smoked DM in the live broadcast program, and not long ago, publicly posted on social media, saying that he wanted to buy Coca-Cola and then add Coco K to it. What good reputation will the brand have with such words and deeds of the boss? Without saying a word, get out of China, I am sorry for the officers and men of the armed police who sacrificed themselves in the front line of anti-drug control!
Perhaps, the five-thousand-year-old rabbit will lose the lawsuit because of some radical rhetoric, and perhaps tesla will win the lawsuit, especially if it wins the case and says that its brakes fail, to a certain extent, it can also cover up the problem. But what about the substance? How has Tesla's reputation been discredited? Is it the self-media remarks of the five-thousand-year-old rabbit, or the actions of the brand itself?
Just on April 30, Xiao Gu, a Tesla Model 3 owner in Hangzhou, also encountered similar problems. Driving on the viaduct, suddenly jumped out of a lot of fault alarms, the owner said that the most intuitive feeling is that the steering wheel suddenly became heavier, the brakes became harder, and it could not be stepped on. The situation is the same as that of Ms. Zhang, who defended her rights on the roof! According to Tesla's response from the Ministry of Foreign Affairs, it is said that the wheel speed sensor is attached to the iron filings, which generate a vehicle alarm, which has been eliminated.
Coincidentally, in May last year, it was also thought that tesla model X owners had a similar situation, and Tesla's response was also caused by dirty wheel speed sensors on the right front wheel. That is to say, the wheel speed sensor is dirty, which will cause the brakes to fail. At least according to Tesla's own words.
However, the wheel speed sensor is generally installed on the back of the hub, this position is very intolerant of dirt, dirty is actually a high probability event. The sensor is dirty, the data is not accurate can be understood, resulting in ABS, ESP error is also a normal phenomenon (because ABS, ESP need wheel speed data), but the sensor is dirty, no brake boost is how many meanings? Without ABS, you can't brake without ESP? Brake first, brake first, brake first! This is the most basic safety logic of car building!
Tesla in order to ensure endurance, the brakes give priority to the use of kinetic energy recovery system to slow down, in the deceleration of 0.3g or less, iBooster line control actuator will make the kinetic energy recovery system work. When more than 0.3g of deceleration is required, ibooster uses brake calipers. When the iBooster system fails, an ESP hev takes over the braking system and provides assistance.
Did you find a problem? How does the system determine the deceleration? The signal of the brake pedal is on the one hand, and there is also a parameter - wheel speed! Wheel speed sensor failure, iBooster can not judge the brake at this time the brake required to reduce the speed, default by the kinetic energy recovery system to work, do not provide brake support, the brake hardened. Even if it is handed over to ESP hev at this time, because there is no wheel speed data, ESP will not work properly.
In this state, if conditions permit, the kinetic energy recovery system can work without brake assistance, but re-braking is effective. (If your Tesla has a similar situation, the solution is to step hard at the first time and use the strength to suckle!) However, if the conditions are not allowed, such as slippery roads, the kinetic energy recovery system is not working, and can only rely on the brakes without help, if there is no preparation, it is indeed very prone to accidents. This is the case of brake failure! Because the brakes in our normal concept are assisted, and without the boost, the brakes harden is failure!
The Tesla brand embodies the arrogance and arrogance of its boss Musk, lacking in reverence for life! Innovation is indeed worthy of recognition, but it should not come at the expense of safety. This reminds me of a sentence by Guo Degang: If you want to innovate, you are a cook, at least you have to know what is a horse spoon, which is a spatula, you take a phlegm bucket to stir-fry and say that it is innovation, so how to eat ah?
The weapon of the law is used to safeguard its own legitimate rights and interests, and cannot be used to intimidate law-abiding people! As a car company with a high reputation in the world, what you should do is to solve the problem, not to use litigation to solve the person who pointed out your problem! At last year's Shanghai Auto Show, when several big men used coercive means to carry female car owners out of the showroom, Tesla's reputation had already fallen to the bottom!
Article 1024 of the Civil Code: Reputation is a social evaluation of the morality, prestige, talent, credit, etc. of a civil subject. Musk, who represents the Tesla brand image, blatantly sucks D, which is moral corruption! Named by the central media, the list of "Annual Report on the Protection of The Rights and Interests of Chinese Consumers (2021)" can be described as infamous! Lack of their own three-power core technology, 90% rely on domestic suppliers, reflecting the ability to be mediocre, shoddy, sales fraud, was sentenced to return one loss of three, but also lost credit! Face is given by others, face is lost by yourself! No virtue, no talent, no faith, no name, their reputation is discredited, what face do you have to say goodbye?
