The invention discloses a motor protection method and device, a storage medium and a vehicle. The method comprises the steps that motor operation parameters, environment load parameters, vehicle operation parameters and user driving parameters are obtained; when the motor operation parameters, the environment load parameters, the vehicle operation parameters and the user driving parameters meet the corresponding triggering conditions, the vehicle is controlled to execute the target event till one or more of the motor operation parameters, the environment load parameters, the vehicle operation parameters and the user driving parameters do not meet the corresponding triggering conditions, controlling the vehicle to cancel execution of the target event; the target event is used to torque limit the electric machine. According to the method, when the motor is subjected to load impact, the motor is protected by limiting the torque of the motor and reducing damage to the motor caused by load impact, and then the torque limitation of the motor is relieved under the condition that it is determined that the motor is not subjected to load impact any more, so that normal use of the motor is restored, and the vehicle power requirement of a driver is met.

    本申请公开了一种电机保护方法、装置、存储介质和车辆,该方法为:获得电机运行参数、环境负载参数、车辆运行参数以及用户驾驶参数;当电机运行参数、环境负载参数、车辆运行参数以及用户驾驶参数符合对应的触发条件时,控制车辆执行目标事件,直至电机运行参数、环境负载参数、车辆运行参数以及用户驾驶参数中的一项或多项不符合对应的触发条件,控制车辆取消目标事件的执行;目标事件用于对电机进行扭矩限制。该方法在电机遭受负载冲击时,通过对电机进行扭矩限制,减少负载冲击给电机带来的损伤,起到电机保护作用,而后在确定电机不再遭受负载冲击的情况下,解除电机的扭矩限制,以恢复电机的正常使用,满足驾驶者的车辆动力需求。
