On January 24, a Tesla rear-end accident in Shanghai this morning caused a heated discussion on the Internet, and then a suspected owner responded.
From the scene, a Tesla Model 3 rear-ended three cars in front of it on the viaduct, resulting in different degrees of damage to four vehicles. Among them, the rear Tesla due to the low front of the car, directly in front of the BYD SUV tail "shovel", BYD SUV directly riding on the Tesla front, resulting in Tesla front, cover and front windshield damage.
Later today, the owner of the model 3 suspected of being involved responded that the automatic driving function was turned on at that time (note: actually the Ap automatic auxiliary driving function), the following distance was set to 1 (the shortest follow-up distance), and the front car 80 yards (note: actually 80km/h) suddenly braked sharply, although the system reacted to the alarm reminder, but an accident still occurred.
In addition, from the scene point of view, the road surface may be relatively slippery after the rain, and the too close to the car and the poor ground condition may be the main factors in this accident.
According to the instructions of Tesla Model 3, the follow-up distance setting of Tesla assisted driving is divided into 1 (minimum follow-up distance) to 7 (maximum follow-up distance). Each setting corresponds to a time-based distance that represents the time it takes for the vehicle to reach the front and rear bumpers from its current location.
If you drive at a faster speed on the ring road or highway, the braking time of the vehicle is generally more than 3 seconds, and then calculate the system reaction time and the possible uncertain ground dry and wet environment, so it is recommended to set the distance above 4, and the good road traffic jam in the city can be set to 1-2 to prevent the distance from being too large and causing other vehicles to be jammed.
It is worth mentioning that Tesla's automatic assisted driving is only L2 level assisted driving function. After turning on this function, the driver still needs to keep his attention on the road, his hands cannot leave the steering wheel and is ready to take over the vehicle at any time, and the driver is still the main person responsible for the safe operation of the vehicle. In the event of an accident, the feature will not be liable.
