The invention discloses a motor driving fault monitoring method, a motor controller and a vehicle, and the method comprises the steps: obtaining a current deviation during motor driving when a fault signal used for representing that a motor has a driving fault is detected; judging whether the fault signal is an effective signal according to the current deviation; if yes, the fault signal is responded to execute the motor safety protection action, otherwise, the fault signal is ignored, and the current driving state of the motor is kept unchanged, so that effective and accurate recognition of the motor driving fault signal is achieved, the coping capacity of a vehicle to abnormal conditions is improved, the unnecessary shutdown risk is reduced, and the safety of the vehicle is improved. Reliable operation of the vehicle under various working conditions is powerfully guaranteed, and then safety and stability of the vehicle in the running process are improved.

    本发明公开了一种电机驱动故障监控方法、电机控制器及车辆,该方法包括:检测到用于表征电机存在驱动故障的故障信号时,获取电机驱动时的电流偏差;根据电流偏差判断故障信号是否为有效信号;若是,则响应故障信号,以执行电机安全保护动作,否则,忽略故障信号,保持电机的当前驱动状态不变,从而实现对电机驱动故障信号的有效、精确识别,提升了车辆对于异常状况的应对能力,减少了不必要的停机风险,有力地保证了车辆在各种工况下的可靠运行,进而提高了车辆行驶过程中的安全性和稳定性。
