On July 28, the Guigang section of the Liubei Expressway, after an accident occurred in a Lexus business vehicle, the door was locked. After three people were trapped, the driver over the road rescued two people, and the vehicle ignited the fire. It is reported that "" Lexus accident "Save man driver voicing: The female passenger's legs cannot be pulled out, and it is distressed to see her death"). A preliminary investigation of the police said that this was a unilateral traffic accident. Industry experts said that if the vehicle control unit is damaged, unlocking instructions cannot be issued. Mr. Liang, a person in the industry, said that the doors were locked and caught in a small probability event after the collision, but it also occurred on this million -class Lexus business car.

According to police reports, Zhu Moumou drove Gui A's small ordinary passenger car and the road intermediate waveform guardrail in the road, limited to viaduct cement pier collisions, causing passengers Chen Moumou to die, Peng Moumou suffered slight injuries, Zhu Moumou A minor injury. This is a unilateral traffic accident, and the cause of the accident is under further investigation.

Jimu Journalists noticed that the Lexus LM manual of the accident model showed that all the doors would be unlocked in the case of SRS airbags (inflated). The live video shows that the airbags in the front row of the car have all started, so why is the door locked?

On July 30, Mr. Liang, a technician engaged in the performance test of a vehicle company, told Jimu Journalists that in accordance with relevant regulations, the entire car door should be unlocked when the accident occurred. There are two possibilities of the door of the accident. The first case is that the body is deformation and the door is stuck, but the door can be seen in the video that the door has no particularly serious deformation. The second situation is that the electrical failure of the vehicle fails, so after a car accident, the door locks in time. Judging from the current police notification and on -site videos, the probability is caused by the damage of the vehicle's electrical system.

An expert who specializes in car collision experiments told Jimu Journalists that the GB national standard and CNCAP standards required the vehicle to open the door after the vehicle collided. At the same time, the system cut off the oil circuit. Generally, after the vehicle suffers a speed of 60 kilometers per hour, the door can open the door, and the vehicle cannot get angry within 30 minutes. The accident vehicle is likely to have too much impact when the collision occurs, directly damaging the cockpit control unit, which makes it unlocking instructions.

Regarding the cause of the fire of the vehicle, the expert said that one may be that after the control unit was damaged, and the instruction could not be issued to cut off the oil circuit, which caused the high temperature to fire, or it may be caused by the short circuit of electricity. Survey results.

Mr. Liang said that there were two main reasons why the incident attracted attention. One is that the door is locked and caught after the collision. Both of them are small probability events; the second is that these two small probability events occur on a million -class Lexus business car at the same time. Essence He believes that the cause of the car is more likely to be caused by the fire after the electrical system is short -circuit. From the perspective of the live video, it should not be the reason for the fuel system. The final reason can only look at the relevant identification results.
