The invention relates to the technical field of vehicle safety systems, in particular to a method for automatically unlocking a vehicle door after vehicle collision, which comprises the following steps of: judging whether a safety air bag needs to be opened or not according to data acquired by a collision sensor, and judging whether the vehicle door needs to be unlocked or not according to data acquired by a pressure sensor and a temperature sensor; wherein in the process of analyzing the temperature sensed by the temperature sensor, a first temperature threshold value and a second temperature threshold value are set, the first temperature threshold value is regarded as the positive condition of ignition, the second temperature threshold value is regarded as the possible condition of ignition, and the temperature rising trend is judged by predicting a B spline curve; the initial temperature and the control point are compared with the reference B spline curve to predict whether the fire occurs, so that the fire prediction accuracy is improved, and unnecessary casualties caused by door unlocking delay due to delayed prediction of the temperature sensor on the fire condition are avoided.

    本发明涉及车辆安全系统技术领域,尤其一种在车辆碰撞之后车门自动解锁的方法,其技术方案包括:通过碰撞传感器采集的数据判断是否需要打开安全气囊并且通过压力传感器和温度传感器采集的数据判断是否需要进行车门解锁,其中,在对温度传感器感知温度的分析过程中,设立第一温度阈值和第二温度阈值,将第一温度阈值视为着火的肯定情况,将第二温度阈值视为着火的可能情况,通过预测B样条曲线判断温度上升趋势,与参考B样条曲线进行起始温度和控制点的比较预测是否着火,提高预测火灾的准确性,避免温度传感器对火灾情况的延时预测导致车门解锁的延后造成不必要的人员伤亡。
