The invention provides a control method of a vehicle motor, which is applied to a power domain control unit in a vehicle, and comprises the following steps: acquiring abnormal states of the vehicle motor in various control modes and operation states of control functions in the control modes; determining normal operation of the vehicle motor in one or more control modes according to the acquired abnormal states of the vehicle motor in the various control modes and the operation states of the control functions in the control modes; and determining an operation sequence for executing motor damping operation corresponding to the one or more control modes, and instructing a motor controller to control the vehicle motor to execute the operation sequence so as to realize damping treatment on the vehicle motor. Through the scheme, corresponding torque intervention can be performed on the motor according to the running conditions of the vehicle motor under different vehicle stability control functions, so that shaking generated by sudden torque change caused by the motor is inhibited, and the driving comfort is improved.

    本申请提供了一种车辆电机的控制方法,应用于车辆中的动力域控制单元,所述方法包括:获取车辆电机在各种控制模式下的异常状态以及所述控制模式下控制功能的运行状态;根据所获取的车辆电机在各种控制模式下的异常状态以及所述控制模式下控制功能的运行状态,确定所述车辆电机在一种或多种控制模式下正常运行;确定对应于所述一种或多种控制模式执行电机减震操作的操作序列,并指示电机控制器控制所述车辆电机执行所述操作序列,以实现对所述车辆电机的减震处理。通过以上方案,可以针对车辆电机在不同车辆稳定控制功能运行情况,对电机进行相应的扭矩干预,从而抑制电机引起扭矩突变产生的抖动,提升驾乘舒适性。
