The embodiment of the invention discloses an automobile collision passenger protection method, device and system. An airbag controller receives a collision signal sent by a collision sensor and controls a safety belt on a seat to tighten according to an acceleration corresponding to the collision signal. Moreover, the airbag controller controls the safety belt to release force when the collision time reaches the preset time according to the front-back position information of the seat and the extension length of the safety belt, so the purposes of reducing the pre-tightening force of the safetybelt and avoiding injuries to the thoracic cavity of a passenger are achieved, female passengers are prevented from being impacted, meanwhile, injuries to the thoracic cavity of the passenger are avoided, and more effective safety guarantee is brought to the passenger.
本发明实施例公开了一种汽车碰撞乘员保护方法、装置及系统。安全气囊控制器接收到碰撞传感器发送的碰撞信号,根据碰撞信号对应的加速度控制座椅上的安全带收紧。并且,安全气囊控制器根据座椅前后位置信息和安全带伸出长度,在碰撞时间达到设定时间时控制安全带泄力。达到通过使安全带的预紧力减小,避免对乘员的胸腔造成伤害的目的,实现避免女性乘客免受撞击的同时,以及避免乘员胸腔造成伤害,给乘员带来更有效的安全保障的效果。
