Active return control method, electric power steering system and automobile

The invention discloses an active return control method, an electric power steering system and an automobile. The method comprises the following steps: acquiring actual data of a vehicle, wherein the actual data of the vehicle comprises an actual vehicle speed and an actual steering angle of a steering wheel; according to the actual vehicle speed and the actual steering angle of the steering wheel, a first target return rotating speed is obtained; smoothing the first target return rotation speed to obtain a second target return rotation speed; and performing active return control according to the second target return rotating speed. The method can achieve the purposes that the aligning residual angle of the steering wheel passing through the middle position is small and the steering torque sudden change of the steering wheel passing through the middle position is avoided. 本发明公开一种主动回正控制方法、电动助力转向系统和汽车。该方法包括：获取车辆实际数据，所述车辆实际数据包括实际车速和方向盘实际转角；根据所述实际车速和所述方向盘实际转角，获取第一目标回正转速；对所述第一目标回正转速进行平滑处理，获取第二目标回正转速；根据所述第二目标回正转速，进
