The invention provides an electric drive system and a torque zero-crossing control method thereof, and the torque zero-crossing control method of the electric drive system comprises the steps: an electric drive controller judges a torque zero-crossing mode; the slope of the torque is changed according to the torque change rate corresponding to the torque zero-crossing mode; and zero-crossing control is completed. Mode subdivision is carried out on the torque zero-crossing working condition, smooth control over the torque can be achieved, the torque response speed can be guaranteed, and rotating speed fluctuation and power impact caused by torque zero crossing are reduced.

    本发明提供了一种电驱系统及其扭矩过零控制方法,其中,电驱系统的扭矩过零控制方法包括:电驱控制器判断扭矩过零模式;按照扭矩过零模式对应的扭矩变化率对扭矩的斜率进行改变;完成过零控制。对扭矩过零工况进行模式细分,既能实现扭矩的平滑控制,又能保证扭矩响应速度,降低扭矩过零引起的转速波动和动力冲击。
