The invention relates to a motor anomaly detection method, a storage medium, a controller and a vehicle. The method comprises the following steps: determining a first current peak value of a first phase, a second current peak value of a second phase and a third current peak value of a third phase of a motor in a target detection period; determining at least one peak difference value according to the first current peak value, the second current peak value and the third current peak value; and determining whether the motor fails or not according to the at least one peak difference value. Therefore, whether the motor breaks down or not can be quickly determined through the peak value and the peak value difference value of the three-phase current, calculation is simple, fault detection efficiency is high, additional hardware detection circuits do not need to be additionally arranged, detection can be achieved under various operation states of various motors, and the application range is wide.

    本公开涉及一种电机异常检测方法、存储介质、控制器及车辆。所述方法包括:确定在目标检测周期内电机的第一相的第一电流峰值、第二相的第二电流峰值和第三相的第三电流峰值;根据所述第一电流峰值、所述第二电流峰值和所述第三电流峰值,确定至少一个峰值差值;根据所述至少一个峰值差值,确定所述电机是否故障。由此,可以通过三相电流的峰值及峰值差值,快速地确定电机是否发生故障,计算简单,对故障的检测效率高,且无需增设额外的硬件检测电路,以及,在多种电机的多种运行状态下均能实现检测,适用范围广。
