Shanghai Auto Show’s first day, A scene of “Top Rights” appeared on the Tesla booth, and a woman wearing rights clothes shouted “Tesla brake failed.” After a day of fermentation, this thing quickly came out, and became the “talk” of people who chathed after tea. The initial Tesla Confucian team is very proud and said that it will never compromise and push the mistake to the owner. Who knows that I have been criticized by the media collective point of the media, and I have to apologize the next day. When I face the media, I will have an attitude, saying that I will fully cooperate with the relevant departments, and I will provide the incident in short ago. One minute of driving data before the vehicle. After the release of driving data, the public opinion on the network began to present two poles differentiation. Some people say Tesla was embarrassing. The root cause is that the driver did not travel as specified; and another sound called Tesla It is not complete, and it is not possible to show that the vehicle is completely no problem.
First, if you want to figure out the Tesla brakes, you first need to understand how the brake system works? In the era of fuel trains, the brakes are realized by mechanical structures. After the brake pedal is pressed, the hydraulic cylinder is controlled to make the brake caliper clamping the brakes. The new energy models like Ttersra generally use electrical signals to control brakes, that is, the system is transmitted to the electrical signal to the main cylinder by detecting the driver, and then transforms to the electrical signal to the master cylinder, after the pressure is transferred, the pressure will pass the brake tubing To the caliper, the braking force will generate. The pedal, the main cylinder, the brake caliper is because the relationship is
But Tesla gives this form display, just tell us that the master is decompressed, so there is also a braking force, But only the driver is missing the data to the pedal, so we can’t sieve from Tesra, indicating that its brake system has no problem.
Since there is no pedal data, then we focus on the existing master cylinder pressure and speed. First, at 6: 14: 25.41, the speed was 94km / h at the time. At this time, the table showed the brake main cylinder pressure of 45.9 bar, and the moment of collision, that is, 6: 14: 27.45, speed is 48.5km / h The main cylinder pressure came to 100 Bar, which was about 2 seconds, and the speed was less than 50km / h. This is obviously abnormal, because Model 3 brakes are very excellent, speed 100km / h to the brakes only about 35 meters, and the front brake distance before the accident car must be more than 40 meters, which is obviously unreasonable. This is also divided into two aspects, one is that the driver did not step on the brakes, leading to insufficient power, and the second is that Tesla brakes are really problematic. 
The first conclusion is difficult to confirm that Tesla did not give the driver’s detailed data to the brake pedal, but if There is a matter of a problem with Tesla brakes, it seems to be a bit. From the view, 6: 14: 26.39, AEB automatically emergency brake intervention, the next moment, that is, 6: 14: 27.45 directly crashed. Before the AEB system is involved, the master cylinder pressure has not broken hundred until the AEB system is intervened, the main cylinder pressure is rapidly improved. Everyone may wish to think that when the normal driver will see the collision in front, is it a play to fight brakes, rather than waiting for the anti-collision system to help you stepping on the brakes, let alone the driver at the time, that is, the father of the rights of the rights, has been driving for many years Experienced old hands, it is impossible to step on the brake. According to Tesla’s statement, 40 bar is just light step, but if it is just a light on the brake, why is it at 6: 14: 25.87, the main cylinder pressure is not high but the ABS system is involved?
Comprehensive, even now Tesla is now on driving data, but still can’t explain that its brakes are not problematic, but it is iBOSTER and early days. Model 3 has had a certain safety hazard in terms of brake calibration, according to the owner of the owner, the brake pedal does not step on it, this is just IBThe phenomenon of failure of OSTER. If Tesla itself is innocent, it is entirely the operation problem of the owner, why not release the full form?
