The invention provides a vehicle door unlocking control method and system for vehicle collision and a vehicle, the vehicle door unlocking control method for vehicle collision comprises the following steps: in response to a first trigger event that a collision acceleration signal reaches a safety air bag ignition threshold value, sending a vehicle door locking signal; after the door locking signal is issued, a door unlocking signal is issued in response to a second trigger event in which the speed signal drops to zero. According to the scheme, the vehicle door locking signal is sent out when the collision acceleration signal reaches the safety air bag ignition threshold value, and after the vehicle door locking signal is sent out and under the condition that the speed signal is reduced to zero, the vehicle door unlocking signal is sent out, so that the vehicle door can be always in the locking state in the period from the collision of the vehicle to the complete static state of the vehicle, and the safety of the vehicle is improved. Therefore, in the period, the passengers in the vehicle can be protected in the compartment due to the closing of the vehicle door, and the problem that the passengers in the vehicle are thrown away from the vehicle to cause secondary injury due to the fact that the unlocking time of the vehicle door goes wrong after the vehicle is collided is avoided.

    本公开提供了一种车辆碰撞的车门解锁控制方法、系统和汽车,该车辆碰撞的车门解锁控制方法包括:响应于碰撞加速度信号达到安全气囊点火阈值的第一触发事件,发出车门锁止信号;在发出车门锁止信号之后,响应于速度信号降为零的第二触发事件,发出车门解锁信号。本公开方案在碰撞加速度信号达到安全气囊点火阈值时发出车门锁止信号,在发出车门锁止信号之后,并在速度信号降为零的情况下,发出车门解锁信号,使得车辆在发生碰撞开始到车辆完全静止的期间内,车门能够始终处于锁止状态,从而在此期间内的车内乘员会因为车门的关闭而将车内乘员保护与车厢内,避免了车辆碰撞后车门的解锁时机出现问题而造成车内乘员甩离车辆导致二次伤害的问题。
