This fully shows that it is true that Tesla can’t stop. Therefore, Tesla was willing to spend money to settle and let the owner issue an apology. If the evidence of the car owner is insufficient and the situation cannot be reproduced, Tesla will ignore the car owner, just like the previous Henan car owner. Attachment: I think it should be the BUG of Tesla’s trip computer that caused the inability to stop. In-depth analysis: Tesla’s brakes are BUG, which causes the brakes to be inoperable. It is recommended to wait for a comprehensive OTA to solve the problem before considering buying On March 11, a consumer’s Tesla model 3 suffered a brake failure and a car crash in Hainan. Unexpectedly, when the official Tesla staff reappeared, the brakes failed and the car crashed at a speed of 30km/h. Tesla first responded: “The ground is slippery and the brake pedal is lightly stepped on.” However, it is obvious from the video that the stagnant water on the road section is not deep, which is similar to the rainy road area. Reply again: “ABS function is invalid”. This response is obviously to fool the ignorant masses. It is impossible for ABS to fail in the case of crazy sales in the video. In Tesla’s own product manual, there is no description that the braking force will disappear completely. Let me first analyze Tesla’s braking system. Tesla uses Bosch’s second-generation ibooster system. The braking performance is strong, the braking distance is within 40 meters at 100km/h, and the braking distance at 30km/h is 3 meters. In other words, the hardware of Tesla Model 3 can definitely be braked. (In fact, Wuling’s drum brakes can do it all) But in the video, the biggest problem is not braking. Similarly, Tesla sent an unauthoritative third-party test, which also shows that the brake system is okay. I checked the Bosch website. Bosch’s iBooster system cancels the vacuum booster. The brake boost is done by the motor inside the assembly. The brake pedal and the push rod of the iBooster assembly are only used to collect signals. In this way, the iBooster system that relies on the motor to achieve power can control the pressure more accurately, allowing engineers to reprogram according to the gearbox gear, speed, steering angle, lateral acceleration or drive mode, etc., to achieve different pedal feel or Braking characteristics. In other words, this set of brake system allows engineers from major auto manufacturers to adapt the battery on the trip computer according to the motor performance of their cars. Namely: Gasoline car: Step on the brake pedal-the brake signal is transmitted to the vacuum booster (vacuum booster pump)-the booster amplifies the brake to stop the car. When the gasoline car is turned off, the vacuum booster pump has no power, so the brakes are particularly hard. However, the physical connection between the brake pedal and the brake system is still there, and the brake can still operate. Bosch’s iBooster system: Step on the brake pedal-the brake signal is sent to the trip computer-the trip computer is sent to the iBooster assembly-the brake is completed. This system is widely used in BYD Han and other new energy vehicles. Go to search for BYD’s description of this system: BYD emphasized one point: In the case of traffic jams following the car in the city, emergency braking is actually needed at this time, and this comfortable function is not required, and corresponding strategies have been made. . For example, when the driver quickly steps on the pedal, or when the pedal is pressed a little deeper, the computer actively exits the intervention, and then follows the driver’s braking request. That is, the driver directly controls the brakes in an emergency. That is: when you brake suddenly, step on the brake pedal-the brake signal is directly transmitted to the iBooster assembly-the brake is completed, and what about the Tesla model3? In order to deeply integrate the iBooster system with its own AutoPilot, Tesla has made a lot of “magic changes” to the software control system, and at the same time, it does not allow the driver to directly control the iBooster system. Namely: Tesla brake system: Step on the brake pedal-the brake signal is sent to the trip computer-the trip computer is sent to the iBooster assembly-the brake is completed. If the Tesla trip computer has a bug, the brake system cannot receive the brake directly from the driver. Signal and then finish braking. Such problems are not without precedent. The earlier Honda CR-V and the recent BMW Brilliance iX3, X5 and other vehicle recalls all mentioned that there are problems with the vehicle’s integrated braking system (IB), which may cause the loss of brake assist and the braking distance has been extended. Why did Tesla dare to do this? This is the difference between traditional car companies and new car manufacturers. Auto companies like BYD that have switched from traditional auto companies to fully invest in new energy vehicles. It is conservative. Many innovations must be tried and tested before they dare to go, and at the same time, they will sacrifice experience and battery life to ensure safety. And Tesla is the most radical car company in the world, from the throttle kinetic energy recovery mode, to the abolition of the dashboard, and then to autonomous driving. Every step is the same as the mobile APP. The version is released first, the function is updated first, and the bug is slowly fixed. Anyway, there is OTA. However, this Hainan accident is just one of the bugs. Finally, I sincerely recommend that Tesla owners ask Tesla to pay attention to and solve such bugs, and others will consider buying Tesla after a full OTA has solved the problem. Relevant state departments intervened in a timely manner to request Tesla rectification. If you are Musk’s iron fan and are willing to use your life to add new fuel to the rockets of human progress, then I didn’t say it.
