The invention relates to the technical field of motor vehicles, in particular to a steering wheel return control method and device, a vehicle and a storage medium, and the method comprises the steps that when a first difference value between a current angle of a steering wheel and a target return angle is not larger than a preset error value, a first rebound angle of the steering wheel is obtained after a first preset duration; when the first springback angle is not larger than a preset springback angle, it is judged that the vehicle completes steering wheel alignment, otherwise, a first target rotation angle of the steering wheel is determined according to the first springback angle, reverse adjustment is conducted on the steering wheel based on the first target rotation angle, a new current angle of the steering wheel is obtained, and a second springback angle of the steering wheel is obtained based on the new current angle; the second springback angle is not greater than the preset springback angle. Therefore, the problem of inaccurate compensation angle acquisition caused by the influence of factors such as a suspension system, tire parameters and road surface types is solved by accurately acquiring the steering wheel rebound angle and automatically compensating the torque increased due to tire deformation, and the steering wheel return accuracy is improved.

    本申请涉及机动车技术领域,特别涉及一种方向盘回正控制方法、装置、车辆及存储介质,包括:在方向盘当前角度与目标回正角度间的第一差值不大于预设误差值时,第一预设时长后获取方向盘的第一回弹角度;第一回弹角度不大于预设回弹角度时,判定车辆完成方向盘回正,否则,根据第一回弹角度确定方向盘的第一目标转角,基于第一目标转角对方向盘进行反向调节,得到方向盘新的当前角度,基于新的当前角度获取方向盘的第二回弹角度,直至第二回弹角度不大于预设回弹角度。由此,通过准确获取方向盘回弹角度,自动补偿由于轮胎形变增加的力矩,解决由于悬架系统、轮胎参数、路面类型等因素影响导致补偿角度获取不准确的问题,提高方向盘回正的准确性。
