The invention provides an active return-to-center control method and device for a vehicle steering wheel, a medium and a vehicle. The active return-to-center control method comprises the steps that steering wheel steering angle information and vehicle speed information are obtained; determining a first torque based on the steering wheel steering angle information and the vehicle speed information; obtaining a median arbitration coefficient based on the steering wheel steering angle information; determining an active aligning torque based on the steering wheel steering angle information, the median arbitration coefficient and the first torque; and feedforward control is carried out based on the active aligning torque so as to realize steering wheel aligning. According to the control method, the feedforward aligning torque is arbitrated, so that the steering wheel can be aligned more smoothly, the conditions of overshoot and insufficient aligning are not prone to occurring, and the aligning effect and the driving experience are improved.

    本申请提供了一种车辆方向盘的主动回正控制方法、设备、介质和车辆。其中的主动回正控制方法包括:获取方向盘转向角信息、车速信息;基于所述方向盘转向角信息和所述车速信息确定第一力矩;基于所述方向盘转向角信息得到中位仲裁系数;基于所述方向盘转向角信息、所述中位仲裁系数和所述第一力矩确定主动回正力矩;基于所述主动回正力矩进行前馈控制,以实现方向盘回正。该控制方法通过对前馈回正力矩进行仲裁,使得方向盘在回正更加平顺,更不容易发生超调和回正不足的情况,从而提高了回正效果和驾驶体验。
