The invention discloses a motor output torque control method and system. The motor output torque control method comprises the steps of obtaining a current rotating speed and an initial output torque of a motor; judging whether the current working condition of the vehicle needs to enable active damping or not according to the current rotating speed; if yes, a PI controller is adjusted according to the current rotating speed to calculate compensation torque; and superposing the initial output torque and the compensation torque to obtain a target output torque of the control motor. According to the technical scheme, active damping control can be conducted on the motor when the vehicle is in the specific working condition, so that vehicle shaking is effectively restrained, and the driving comfort of the vehicle is improved.

    本发明公开了一种电机输出扭矩控制方法及系统。该电机输出扭矩控制方法包括:获取电机的当前转速和初始输出扭矩;根据当前转速,判断车辆当前工况是否需要使能主动阻尼;若是,则根据当前转速调节PI控制器,以计算补偿扭矩;将初始输出扭矩与补偿扭矩进行叠加,得到控制电机的目标输出扭矩。本发明实施例的技术方案可在车辆处于特定工况下时对电机进行主动阻尼控制,从而有效抑制车辆抖动,提高车辆的驾乘舒适性。
