The invention discloses a control method and device of a driving motor and a hybrid vehicle, and relates to the technical field of hybrid vehicle control. According to the control method, the acceleration change rate and the required torque of the driving motor are obtained, and when it is determined that the driving motor is in the shaking state according to the acceleration change rate, the compensation torque of the driving motor is obtained according to the acceleration change rate and a preset first coefficient; therefore, the determined compensation torque can be associated to the overall power output of the hybrid vehicle, when anti-shake control is carried out on the driving motor according to the compensation torque and the demand torque, inhibition processing can be carried out on the ECVT start-stop shake or pause condition through the angle controlled by the driving motor, the impact of a planetary gear on the wheel end of the hybrid vehicle is reduced, and the stability of the hybrid vehicle is improved. And therefore, the smoothness of power output of the hybrid vehicle is improved.
本发明公开了一种驱动电机的控制方法、装置和混动车辆,涉及混动车辆控制的技术领域。控制方法通过获取驱动电机的加速度变化率和需求扭矩,在根据加速度变化率确定驱动电机处于抖动状态时,根据加速度变化率和预设的第一系数获得驱动电机的补偿扭矩,由于第一系数为至少关联混动车辆的发动机转速的补偿系数,因而可以使确定的补偿扭矩关联至混动车辆整体的动力输出,在根据补偿扭矩和需求扭矩对驱动电机进行防抖控制时,可以由驱动电机控制的角度对ECVT启停抖动或顿挫的情况进行抑制处理,减小行星齿轮对混动车辆轮端的冲击,进而提高了混动车辆动力输出的平顺性。
