The invention provides a steering wheel aligning method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that when a preset aligning condition is met, the current initial angle of a steering wheel is obtained, and the steering wheel is controlled to rotate to a target angle; the current holding torque when the steering wheel is controlled to be at the target angle is obtained, and the theoretical rebound angle of the steering wheel is determined based on the current holding torque; after the steering wheel is controlled on the basis of the maximum value between the theoretical rebound angle and the target angle, the torque control of the steering wheel is released. According to the method, the current actual working condition can be mastered on the basis of the current holding torque, then the theoretical springback angle is estimated in advance, the returning of the steering wheel is reasonably controlled in combination with the maximum value between the theoretical springback angle and the target angle, the returning precision is improved, and meanwhile reliable returning control can be achieved even under the complex working condition.

    本发明提供了一种方向盘回正方法、装置、车辆及存储介质,涉及车辆技术领域,该方法包括:当满足预设回正条件时,获取方向盘的当前初始角度,并控制方向盘旋转至目标角度;获取控制方向盘处于目标角度时的当前保持扭矩,并基于当前保持扭矩确定方向盘的理论回弹角度;基于理论回弹角度和目标角度之中的最大值控制方向盘后,解除对方向盘的扭矩控制。本发明基于当前保持扭矩有利于掌握当前实际的工况,进而提前预估理论回弹角度,并结合理论回弹角度与目标角度之中的最大值,对方向盘的回正进行合理控制,提高回正精度同时,即使面对复杂工况也能够实现可靠的回正控制。
