Beijing News Shell Finance News (Reporter Lin Zi) On the evening of April 22, Tesla provided reporters with one-minute data on the "brake failure" accident that had been questioned before. Tesla said that the company consulted with legal personnel, and since the data is privately owned by the car owner, it is not convenient for Tesla to disclose more data unless the car owner releases it himself.
According to Tesla, in the 30 minutes before the vehicle accident, the vehicle had a record of more than 40 pressings on the brake pedal.
Tesla said that when the driver pressed the brake pedal for the last time, the data showed that the vehicle was traveling at 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9bar, and then the driver stepped on the brake pedal more, and the brake master cylinder pressure reached 92.7bar, followed by The forward collision warning and automatic emergency braking functions were activated (the maximum brake master cylinder pressure reached 140.7bar) and played a role, reducing the magnitude of the collision. 1.8 seconds after the ABS function, the system recorded the occurrence of the collision. After the driver depressed the brake pedal, the vehicle's speed continued to decrease to 48.5 kilometers per hour before the collision.
In summary, the vehicle is moving at a high speed, and the driver starts to depress the brake pedal lightly. After that, the automatic emergency braking function starts and plays a role, increasing the braking force and reducing the impact of the collision. The braking systems all intervene normally and reduce the speed of the vehicle.
In the 30 minutes before the vehicle accident, the driver drove the vehicle normally, and there was a record of pressing the brake pedal more than 40 times. At the same time, the vehicle exceeded 100 kilometers per hour many times and braked many times.
