The EDR data surveyed by Belt showed that there was no brake during the accident, but longitudinal accelerometer data and Tesla log data both confirmed that the driver had braked. In other words, the system is in conflict.īecause the EDR (Event Data Recorder) data of Tesla Model 3's sudden acceleration event revealed inconsistencies between EDR data, driver testimony, and analysis of accident log data issued by Tesla itself. Prior to this, he participated in a well-known investigation into Toyota's sudden acceleration in 2010.Īfter testing the stalled Tesla Model 3 (Configuration |Inquiry), his analysis is that the reason for the sudden acceleration of the vehicle is the braking system and its interaction with the energy regeneration system. Belt conducted an independent investigation into a sudden acceleration of Tesla and published a 66-page investigation report. Next, starting in June last year, American Dr. Although this probability is very low, it is not unavailable. However, there is also a fatal problem with the brake-by-wire system, that is, if there is an error, delay, or interruption in the transmission of the electrical signal, it is very likely to bring the brake failure, sudden acceleration and other dangers. In order to complete the energy recovery process.Īs a pioneer in the field of electric vehicles and autonomous driving, Tesla naturally used this system very early, officially called the "automatic emergency braking system", and this function has also been integrated in the AutoPilot system. The current passes through components like capacitors and rushes back into the battery after being stabilized. The energy of the front brake of the car will drive the rotor of the motor to cut the magnetic induction line to generate current. In other words, it turns the motor of the wire control system into a generator. The wire control system is not only fast in response and small in space, but also very well adapted to the needs of energy recovery and autonomous driving.

In other words, the braking action that was previously done by mechanical braking structure has been turned into electronic control. Here to explain, the current brake-by-wire system of pure electric vehicles detects the strength of the brake pedal by the owner and converts it into a corresponding electrical signal to the system, and then the brake-by-wire system drives the hydraulic system to complete the brake. What is going on with the brake failure? After all, Tesla and most current electric vehicles use the iBooster wire-controlled (ie, electronically controlled) brake system developed by Bosch, so does "brake failure" have anything to do with Bosch? As reporters, we are more curious to explore, technically speaking, what is the conclusion? However, there is still a cloud of fog. On both sides of this matter, "the public said that the public is reasonable, the mother said that the mother is reasonable", there is a lot of information hidden behind both sides, and there is no clear answer at present. In the final analysis, the core of this matter is whether the Tesla brakes failed? Did the driver misuse it? This finally caused the public to be vigilant about the safety performance of Tesla vehicles and even reassessed. As things fermented, interpretations were also overwhelming. Tesla's "brake failure" rights protection incident can be said to be the most sensational event at the Shanghai Auto Show. Brake failure "Rashomon" | Tesla brake door 18:27:24 Automobile Commune
