The invention provides a crawling safety control method for a pure electric vehicle, which belongs to the technical field of pure electric vehicle safety control. The method comprises the steps that vehicle door state signals are received, and crawling torque output is forbidden as long as one of the four door state signals is opened; and an accelerator opening signal is monitored, and under the condition that the four doors are closed, as long as the accelerator opening exceeds the limiting value, crawling torque output is recovered. According to the safety control method provided by the invention, under certain special working conditions, if crawling occurs, for example, under the condition that the vehicle doors are not closed, creeping torque is ensured to be output only under the condition that the four doors are closed, and driving safety under the crawling working conditions is ensured.

    本发明提供一种纯电动汽车蠕行安全控制方法。属于纯电动汽车安全控制技术领域。方法为:接收车门状态信号,四个门状态信号只要有一个开启,则禁止蠕行扭矩输出;监控油门开度信号,在四门状态关闭情况下,只要油门开度超过限值,恢复蠕行扭矩输出。本发明提供的安全控制方法,在某些特殊工况如果出现蠕行,比如车门未关情况下,确保在四门关闭的情况下才有蠕行扭矩输出,保证蠕行工况的行车安全。
