The invention relates to the technical field of automobile engines, in particular to an engine jitter suppression method, which realizes an engine torque smoothing function by adjusting the output torque of a motor, and is characterized in that the compensation torque of the motor is added to suppress the torque pulsation of the motor. Smooth of engine torque is achieved by adjusting the output torque of the motor, torque pulsation of the engine is restrained, vibration of a mechanical system is reduced, the mechanical service life is prolonged, comfort is improved, the phase is adjusted preferentially, it is guaranteed that jitter of the engine is exactly weakened through compensation torque, then the sine wave amplitude is adjusted, and the jitter restraining effect is optimal.
本发明涉及汽车发动机技术领域,尤其是一种发动机抖动抑制的方法,通过调整电机的输出转矩来实现发动机转矩平滑功能,其基本思想是增加一个电机的补偿转矩来抑制电机的转矩脉动,本发明通过调整电机的输出转矩来实现发动机转矩的平滑,抑制发动机的转矩脉动,减少机械系统振动,延长机械使用寿命,提升舒适性,优先调节相位,保证补偿转矩刚好削弱发动机的抖动,然后再调正弦波幅值,使得抖动抑制的效果最佳。
