The invention relates to a rear wheel steering control method and device of a vehicle, a rear wheel steering controller and a medium, and the method comprises the steps that a turning angle signal of the vehicle is received; determining a front wheel steering angle and a rear wheel steering angle of the vehicle based on the steering angle signal; correcting the rear wheel turning angle by combining the front wheel turning angle and the current working condition of the vehicle to obtain a target turning angle of rear wheels of the vehicle so as to control a rear driving motor of the vehicle to adjust the position of an internal rack, so that the actual turning angle of the rear wheels is consistent with the target turning angle. Therefore, the technical problems that in the prior art, due to the limitation of the arrangement space, the riding comfort and the steering comfort are difficult to consider, and the turning diameter is not easy to reduce are solved.

    本申请涉及一种车辆的后轮转向控制方法、装置、后轮转向控制器及介质,其中,方法包括:接收车辆的转角信号;基于转角信号确定车辆的前轮转角和后轮转角;结合前轮转角和车辆的当前所处工况修正后轮转角,得到车辆后轮的目标转角,以控制车辆的后驱动电机进行内部齿条位置调整,使得后轮的实际转角与目标转角一致。由此,解决了相关技术中,由于布置空间的限制,难以兼顾乘坐舒适性和转向舒适性,不利于减小转弯直径的技术问题。
