The invention belongs to the technical field of automobile door locks, and discloses a vehicle door lock standby power supply system which comprises a door lock unit and a standby power supply, the standby power supply is connected with the door lock unit through a control unit, the control unit judges whether a vehicle collides according to pulse width changes of collision signals, and if the pulse width changes, the standby power supply is started. If yes, it is judged that the vehicle collides, then preset time is delayed, then the standby power supply is controlled to supply power to the door lock unit, and unlocking is achieved; and if the pulse width does not change, judging that the vehicle is not collided, and not performing subsequent processing. According to the method, more serious damage caused by the fact that a vehicle door is opened due to the fact that people touch the vehicle by mistake during rolling of the vehicle can be reduced, guarantee can be provided for safe unlocking of the vehicle door under the crisis situation, smooth implementation of follow-up rescue is guaranteed, and meanwhile whether the vehicle is collided or not is judged according to pulse width changes of collision signals. The vehicle-mounted collision signal self-change rule is better met, the practicability is higher, and the application range is wider.
本发明属于汽车门锁的技术领域,公开了一种车辆门锁备用电源系统,包括门锁单元、备用电源,所述备用电源通过控制单元与门锁单元相连,所述控制单元依据碰撞信号的脉宽变化判断车辆是否发生碰撞,如果脉宽发生变化,则判断车辆发生碰撞,然后延时预定时间再控制备用电源对门锁单元供电,以实现解锁;如果脉宽没有发生变化,则判断车辆没有发生碰撞,不做后续处理。既可以减少车辆翻滚期间由于车内人员误触导致车门打开,造成更严重的伤害,又可以为车门在危机情况下的安全解锁提供保障,确保后续救援的顺利实施,同时依据碰撞信号的脉宽变化判断车辆是否发生碰撞,更加符合车载碰撞信号的自身变化规律,实用性更强,适用面更广。
