First of all, it should be noted that both domestic and foreign statistics show that Tesla is one of the safest cars. Statistics for 2021 show that Tesla's accident death risk is 1/14 of the average, and I remember about the same statistics in the United States. This is thanks to Tesla's advanced body structure and active safety blessing of all vehicle series.
However, since the Henan brake door incident that was put out at the auto show, Tesla has been shrouded in the shadow of safety questioned by the people of the country, and brake failure has almost become synonymous with Tesla. On the one hand, there are indeed several casualty accidents that shocked the country, and the parties intentionally or unintentionally will push the responsibility to the car, on the other hand, it is also fueled by the media and the people who do not know the truth, so the total accident rate of 2/10,000 occupies more than 90% of the exposure rate of serious accidents.
Tesla has several common cases:
1: After suddenly accelerating, it rushed on the road until it stopped, and the reports included Chaozhou, Ruian, Guangzhou, and Wenzhou before.
2: There are brakes during driving, but there is no braking to cause accidents, including the roof of Anyang, Henan Province to protect rights, Guangdong Zhaoqing rushed to 158 kilometers of retired traffic police, and a Changzhou Liyang lane change lane crashed into a small truck.
3: Caught fire after impact: the most famous Lin Zhiying, the Model Y that caught fire under the Hangzhou overpass.
The second problem is actually all vehicles will encounter, that is, drive fast too late to brake, Changzhou Liyang owner took the initiative to admit that he was careless to drive fast after the accident, and posted his own driving license to prove, very responsible. Anyang that is not their own car, a road to the black is still there toss, I don't know where the courage comes from, Tesla data is so detailed, fully proved that the brakes are not timely, the simplest is to see that ABS has been started means that the brakes have reached the maximum adhesion of the tire and the ground, the brakes can do has come to an end, Tesla fraud is impossible, what are the consequences of a world-wide large company fraud? And there are so many cameras along the road, the car can confirm the authenticity of the data on the side. Zhaoqing's one does not know whether it is out of the relationship of protecting the privacy of the accident party, and there is no investigation information disclosed, but from that video, it is a fast car to accelerate and change lanes but is unsuccessful, braking and changing lanes at that speed are futile, and the beginning of that video is already doomed.
The third problem is the common problem of all electric vehicles that use ternary lithium batteries, high energy density also means flammable and explosive, Tesla has protected the battery as much as possible, the whole car is the bottom of the car is the least susceptible to impact, but unfortunately Lin Zhiying should be deserted to ride the car to the isolation pile, the battery under the car directly hit, in this case fire and combustion is inevitable, Hangzhou friend is also directly hit the chassis that is the least likely to hit.
The point is on the first case, the first thing I want to say is that the car itself should not have any malfunctions. This situation is not simply a problem of complaining about brake failure, but accompanied by the frantic acceleration of the vehicle, hitting all the way. Many people have questioned whether the throttle and brake signal crosstalk, as a person who has been engaged in electronic communication for twenty years, it can be very clear that it is completely impossible, on the one hand, the throttle signal and the brake signal are completely different things, not simply take a wire and put it on the line, this is two completely independent systems, the simplest thing, even if the same system inside, when you hit the left turn signal, have you ever seen the string reverse to the right turn signal? By the way, Tesla's turn signals are also computer-controlled. Moreover, the Bosch iBoost brake system used by Tesla is not used by Tesla, it is a hardware-connected hydraulic mechanism and a one-way booster motor, and the computer can only do to strengthen the brakes or actively brake, and there is no possibility of blocking the brakes at all!
It is claimed that the only possibility of stepping on the brakes but not slowing down but accelerating wildly is to step on the wrong electric door, and the melon-eating masses have to question how it is possible to step on the electric door for several kilometers and do not know how to put it. In fact, such a thing is not unusual at all, the following is only reported by the media: 1, 19 years Xi'an BYD Tang suddenly hit five or six hundred meters left and right, one killed and five injured, 11 years of driving 100,000 kilometers old driver (female), also claimed brake failure. 2, Changsha bus hit 8 cars in a row, this is a bus driver! 3, Hangzhou Mercedes-Benz female driver also avoided left and right, hit 4 dead and 13 injured, if not for their car overturned, the number of casualties may be greater, 4, NIO old driver rushed 2 kilometers, hit 5 cars in a row, unable to move before stopping. Hundreds of gas pedals happen every day in China, resulting in tens of thousands of casualties every year! The common denominator of such serious accidents is that they are highly nervous, subconsciously avoiding vehicles and pedestrians, but their feet are like welding to the accelerator.
Xi'an hit BYD Tang, 600 meters
Hangzhou 4 killed and 13 injured Mercedes
It is not how long or how long they stop that they stop, only to see when the vehicle hits and can't drive at all, many of these situations hit the wall, the tires are still frantically gouging the ground... And once this kind of accident occurs, all the perpetrators will claim to be the old driver, and the brakes fail, but in fact, the identification result of such accidents in the whole world is that the accelerator is used as a brake, and there is no exception!
Although it can be determined that Tesla did not have any abnormalities at the time of the accident, it does not mean that Tesla's design is without hidden dangers! Tesla all series with assisted driving function (AP), the moment the AP is opened, the vehicle will fix the speed to the maximum speed limit of this section (this speed can be set offset in advance) and immediately executed, regardless of whether the accelerator is pressed, the default is the speed limit of this section. The AP lever of this AP switch Model S/X has a separate small gear lever at the bottom left of the steering wheel, but the Model 3/Y is integrated into the right gear lever and shares a gear lever with the shift function.
The problem is that if the right gear lever is pressed down while driving, the AP is immediately triggered, and the vehicle will automatically accelerate, and this gear lever is very easy to be touched by mistake, such as when turning right, the brain is mixed up with the left hand pressing the gear lever has become the right hand press... As an old driver who drove a Tesla for 200,000 kilometers, I also missed it twice, and I was going to turn very slowly, and suddenly began to accelerate, of course, because I am very, very familiar with the car, the AP function is also often used, after a very, very short doubt, immediately understand what happened, tap the brake and lift.
But I believe that if you find a random Tesla owner on the street and ask him about this feature, at least three or five out of ten have not even turned the manual, let alone the car they drive. Once a false touch occurs, the first reaction of the average person is to step on the brake, of course, the automatic acceleration is lifted, but people who are not familiar with the vehicle will be very flustered, without stepping on the accelerator but automatically accelerating, this is a very scary thing, in a panic in case the accelerator is used as a brake press... That's even more terrifying, more flustered... You must know that Tesla's acceleration performance is very good, and the only thing that the blank brain can do is desperately flash left and right!
I guess it is not necessarily the cause of all these accidents, but it must have led to many such accidents, I don't know why Model 3/Y does not follow the small gear lever design of Model S when designing, maybe it is the simplicity of the hardware that Tesla pursues, and the subsequent facelift Model S / X even the gear lever has been canceled, very speechless! But this streamlining must be built on not increasing the chance of misuse! It is very hoped that the appraisal department and the traffic management department will publish the investigation report of the Tesla accident, so that everyone, including Tesla, can understand the factors that may increase the probability of accidents, and can learn from the safety improvement of all car companies later, and it is very meaningful to avoid even an accident!
