The invention discloses a motor torque output anomaly detection method and device and a storage medium, and the method comprises the steps: obtaining a first request torque, and obtaining a first output torque of a motor, the first request torque being used for requesting a motor controller to control the motor to output a torque corresponding to the first request torque, the first output torque is obtained by the motor controller based on a first output parameter of the motor; based on the size relation between the first difference and a target preset threshold value, whether target abnormity exists in the first output torque of the motor or not is determined, and the first difference is the difference between the first output torque and the first request torque. In this way, the abnormal detection efficiency of the output torque of the motor can be improved.

    本申请公开了一种电机扭矩输出的异常检测方法、设备和存储介质,该方法包括:获取第一请求扭矩、以及获取电机的第一输出扭矩,第一请求扭矩用于请求电机控制器控制电机输出与第一请求扭矩对应的扭矩,第一输出扭矩为电机控制器基于电机的第一输出参数获取得到;基于第一差异与目标预设阈值的大小关系,确定电机的第一输出扭矩是否存在目标异常,第一差异为第一输出扭矩和第一请求扭矩之间的差异。通过上述方式,本申请能够提高电机输出扭矩的异常检测效率。
