The invention provides an abnormal autonomous power-off control method and system for an intelligent networked passenger car driving system. The scheme comprises the steps that the state of the driving system is obtained in real time; when the communication of the driving system is abnormal, vehicle speed estimation is carried out based on the vehicle speed stored at the moment before the abnormality and in combination with a wheel speed sensor signal or a brake pedal signal; and when the vehicle speed estimation result is lower than the preset vehicle speed, vehicle high-voltage power-off operation is executed.

    本公开提供了一种智能网联客车驱动系统异常自主下电控制方法及系统,所述方案包括:实时获取驱动系统状态;当驱动系统通信异常时,基于异常前一时刻保存的车速,并结合轮速传感器信号或制动踏板信号,进行车速估计;当车速估计结果低于预设车速时,执行车辆高压下电操作。
