The embodiment of the invention discloses a protection system and method for small offset collision. The protection system comprises an acceleration sensor used for collecting acceleration information of a vehicle in real time, and an air bag controller which is in communication connection with the acceleration sensor and used for judging whether the acceleration information meets the vehicle small-offset collision condition or not according to the acceleration information, and further used for being in communication connection with the air bag controller and used for controlling the wheels to be separated from the vehicle body according to the wheel separation instruction when the acceleration information meets the vehicle small-offset collision condition. According to the protection system, it is effectively guaranteed that the wheels are disengaged when the vehicle is subjected to small offset collision, the deformable space of a collision area is increased, and damage caused by the fact that tires invade a passenger compartment is reduced.

    本发明实施例公开了一种用于小偏置碰撞的保护系统及方法。该保护系统包括:加速度传感器,用于实时采集车辆的加速度信息,气囊控制器,与加速度传感器通讯连接,用于根据加速度信息判断加速度信息是否满足车辆小偏置碰撞条件,还用于在加速度信息满足车辆小偏置碰撞条件时,发送车轮脱离指令,失效控制装置,与气囊控制器通讯连接,用于根据车轮脱离指令,控制车轮与车辆主体脱离。本发明实施例的技术方案,有效保障了车辆发生小偏置碰撞时车轮的脱离,增大了碰撞区域可变形的空间,减小了因轮胎入侵乘员舱造成的伤害。
