Seat adjustment device with rear collision protection function and method thereof

Abstract

The invention provides a seat adjusting device with a tailgating protection function and a seat adjusting method and belongs to the technical field of automobiles. The problem that the safety is not high in the prior art is solved. The seat adjusting device with the tailgating protection function comprises an air bag ECU, a seat control module, a locking mechanism, a first crash sensor, a second crash sensor and a seat putting down mechanism, wherein the locking mechanism is connected with the seat control module, the first crash sensor is arranged on a longitudinal beam, and the second crash sensor is arranged inside a column A. The first crash sensor, the second crash sensor, the seat putting down mechanism and the seat control module are all connected with the air bag ECU. The seat adjusting method comprises the steps that after crashing occurs, whether truck tailgating of a vehicle occurs or not is judged at first, and air bags are directly exploded when common crashing of the vehicle occurs; and when truck tailgating of the vehicle occurs, the seat control module is started to unlock the locking state of seat back angles, and the seat putting down mechanism is started to conduct seat putting down operation. According to the seat adjusting device with the tailgating protection function and the seat adjusting method, the safety of a driver and passengers can be protected when vehicle tailgating occurs.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a seat adjustment device and a method thereof with a rear-end collision protection function. Background technique [0002] Domestic car ownership has risen sharply, and traffic accidents caused by cars have also increased year by year, becoming a major killer of personal safety. The rapid development of highways and the logistics industry has led to more frequent car rear-end collisions with trucks. Every time a rear-end collision occurs, the vehicle will be damaged, people will be injured, and the roof will be cut off and people will die. [0003] The current passive protection for rear-end collisions is only the airbag system. If the rear-end vehicle is high, the roof will be cut off, resulting in the driver and occupants having airbags but still unable to avoid the impact of the rear of the truck on the personnel, resulting in a tragic accident. [0004] In view of the abov...

AI Technical Summary

Problems solved by technology

[0005] 1. Car safety protection is carried out by judging the rear-end collision situation in advance, which is difficult to judge and the accuracy is not high, and there are also cases of misjudgment;

[0006] 2. It is impossible to perform corresponding operations according to the level of rear-end collision. This invention may cause unnecessary safety hazards to drivers and passengers
