The invention belongs to the technical field of pure electric vehicle parking, and discloses a P-gear parking monitoring method, a P-gear parking monitoring system and an electric vehicle. The P-gear parking monitoring method comprises the steps of collecting a wheel speed signal, a P-gear signal and a P-gear parking feedback signal, and judging whether P-gear parking is normal or not according to the wheel speed signal, the P-gear signal and the P-gear parking feedback signal; and if the P-gear parking fails, parking the whole vehicle. The P-gear parking state can be monitored, once P-gear parking fails, whole vehicle parking can be implemented in time, and vehicle sliding hazards are avoided.

本发明属于纯电动汽车驻车技术领域，公开了一种P挡驻车监控方法、监控系统和电动汽车，P挡驻车监控方法通过采集轮速信号、P挡信号和P挡驻车反馈信号，并根据所述轮速信号、所述P挡信号和所述P挡驻车反馈信号判断P挡驻车是否正常，如果所述P挡驻车失效，则进行整车驻车。本发明可以监控P挡驻车状态，一旦P挡驻车失效，可以及时实施整车驻车，避免溜车危害。
