The invention discloses a rear wheel steering control method, system and device, a storage medium and a vehicle, the rear wheel steering control method is applied to the vehicle with a rear wheel steering system, and the rear wheel steering system comprises a lead screw used for controlling rear wheel steering of the vehicle. The actual position angle of the lead screw and the target position angle of the lead screw are obtained, the difference between the actual position angle and the target position angle is determined as the position angle deviation value of the lead screw, the vehicle speed of the vehicle is obtained, and a first preset threshold value is obtained according to the vehicle speed; controlling a rear wheel steering system to align a rear wheel according to the fact that the position angle deviation value is larger than or equal to a first preset threshold value. When the position angle deviation value of the lead screw exceeds the first preset threshold value, the rear wheel can be controlled to return in time, so that the lateral force of a vehicle body is reduced, and the function safety of the whole vehicle is guaranteed.
本发明公开了一种后轮转向控制方法、系统、装置、存储介质以及车辆,后轮转向控制方法应用于具有后轮转向系统的车辆,后轮转向系统包括用于控制车辆的后轮转向的丝杠,包括:响应于后轮开始转向,获取丝杠的实际位置角度与丝杠的目标位置角度,确定实际位置角度与目标位置角度的差为丝杠的位置角度偏差量,获取车辆的车速,根据车速获取第一预设阈值;根据位置角度偏差量大于等于第一预设阈值,控制后轮转向系统将后轮回正。当丝杠的位置角度偏差量超过第一预设阈值时,可以及时控制后轮回正,从而降低车身的侧向力,保证整车功能安全。
