The invention relates to the technical field of automobile safety, in particular to a vehicle door unlocking method and device during vehicle collision. The millimeter-wave radar and the multifunctional camera sense obstacles in the surrounding environment, the intelligent driving calculation center comprehensively calculates and predicts whether a collision risk occurs or not according to the sensed obstacle distance, the current vehicle speed provided by the braking system and the acceleration sensor provided by the air bag controller, and decides whether to send out a pre-collision signal or not; the pre-collision signal is sent to the vehicle body domain calculation center in advance, the vehicle body domain calculation center controls the central control unit to unlock and the hidden door handle to unfold, the purposes of preparation in advance and prevention in advance are achieved, and the risk that people are trapped is reduced.

    本公开涉及汽车安全技术领域,特别涉及一种车辆碰撞时车门解锁方法及装置。本公开毫米波雷达及多功能摄像头感知周边环境障碍物,智驾计算中心根据感知到的障碍物距离及制动系统提供的当前车速、气囊控制器提供的加速度传感器,综合计算,预测是否会有发生碰撞风险,决策是否发出预碰撞信号,提前发送预碰撞信号给车身域计算中心,车身域计算中心控制中控解锁及隐藏式门把手展开,达到提前准备,提前预防的目的,减少人员被困风险。
