The invention discloses an active return-to-center control method based on the rotating speed and angle of a vehicle steering wheel. The method comprises the steps that a current vehicle speed signal and a current steering wheel state signal are obtained; according to the current state signal of the steering wheel, determining a to-be-returned angle and a target returning direction of the steering wheel; according to the current vehicle speed signal and the steering wheel angle signal, determining a target return rotation speed of the steering wheel; determining a steering wheel rotating speed control torque according to the current vehicle speed signal, a steering wheel to-be-corrected angle, the target correcting rotating speed and the steering wheel rotating speed signal; determining a steering wheel angle control torque according to the current vehicle speed signal, the angle needing to be corrected and the steering wheel angle signal; determining an active aligning torque according to the steering wheel rotating speed control torque and the steering wheel angle control torque; and controlling the steering wheel to actively return according to the active return torque and the target return direction. By means of the method, it is guaranteed that the vehicle steering wheel can be automatically returned under different working conditions and different road conditions.
本发明公开了一种基于车辆方向盘转速和角度的主动回正控制方法,包括获取当前车速信号和方向盘当前状态信号;根据方向盘当前状态信号,确定方向盘需要回正的角度和目标回正方向;根据当前车速信号和方向盘角度信号,确定方向盘的目标回正转速;根据当前车速信号、方向盘需要回正的角度、目标回正转速和方向盘转速信号,确定方向盘转速控制力矩;根据当前车速信号、需要回正的角度和方向盘角度信号,确定方向盘角度控制力矩;根据方向盘转速控制力矩和方向盘角度控制力矩,确定主动回正力矩;根据主动回正力矩和目标回正方向,控制方向盘主动回正。利用上述方法,保证了不同工况以及不同路面情况下车辆方向盘均可实现自动回正。
