The invention provides a method and system for achieving steering wheel return after parking, a vehicle and a storage medium. The achieving method comprises the steps that the tire steering friction force is calculated according to the type of a road surface where the current vehicle is located after parking is completed; according to the steering wheel angle information of the current vehicle, obtaining a target reverse angle of a steering wheel of the current vehicle; executing a request instruction of returning to the reverse torque of the steering wheel only when the reverse request of controlling the steering wheel reaches the target reverse angle and exceeds the preset stay time, and outputting a reverse torque signal of the vehicle steering wheel; and counteracting the steering friction force between the vehicle steering wheel and the tires through the reverse torque signal so as to keep the steering wheel to return after parking. By recognizing different ground types, calculating the friction force between the vehicle tires and different grounds and obtaining the torque signal of the vehicle steering wheel, the friction force between the steering wheel and the ground is offset, the steering wheel is prevented from rebounding, the steering wheel is smoothly returned after parking is completed, and therefore the effect that the parking user experience is good is achieved.

    本申请提出的一种泊车后方向盘回正实现方法、系统、车辆及存储介质,所述实现方法包括:根据当前车辆泊车完成后所在的路面类型计算轮胎转向摩擦力;根据当前车辆的方向盘角度信息,获取当前车辆方向盘的目标反向角度;仅当控制方向盘反向请求到达所述目标反向角度超过预设停留时间时,执行回正方向盘反向扭矩的请求指令,输出车辆方向盘的反向扭矩信号;通过所述反向扭矩信号抵消所述车辆方向盘与轮胎转向摩擦力,以保持泊车后方向盘回正。本申请通过识别不同地面类型,计算车辆轮胎与不同地面的摩擦力,通过获取车辆方向盘的扭矩信号,抵消方向盘与地面摩擦力,避免方向盘回弹,让泊车完成后方向盘顺利回正,从而达到停车用户体验好的效果。
