The invention belongs to an electric vehicle safety control method. Problems in the prior art, when a motor fails, a VCU only performs high-pressure treatment, and driving safety is influenced are solved. The invention provides a motor failure safety control method, a computer readable storage medium, and terminal equipment. According to the control method, when motor failure is detected by the VCU, the VCU controls a transmission to return to the neutral gear, meanwhile, the motor is powered off, high voltage reduction is carried out to the whole vehicle after the vehicle is stopped, direct high voltage reduction is replaced, the risk of steering failure possibly caused by direct high voltage reduction in the high-speed driving process is avoided, and the driving safety of the pure electric vehicle is effectively improved. The computer readable storage medium and the control equipment are used as hardware for realizing the safety control method.
本发明属于电动汽车安全控制方法,解决现有技术中电机失效时,VCU仅进行高压处理,影响行车安全的技术问题,提供电机失效安全控制方法、计算机可读存储介质及终端设备,控制方法为,当VCU检测到电机失效后,VCU控制变速器回空挡,同时对电机断电处理,待车辆停下后再整车下高压,而不是直接下高压处理,避免了高速行车途中直接下高压可能带来的转向失灵的危险,有效提高了纯电动车的行车安全性。计算机可读存储介质和控制设备作为用于实现上述安全控制方法的硬件。
