The invention discloses a vehicle rear wheel steering control method and device, a storage medium and an electronic device. The method comprises the steps that vehicle steering input information is obtained; a vehicle side slip angle function is determined based on a vehicle two-degree-of-freedom model, and a vehicle yaw angle function is determined according to the front wheel steering dynamic gain coefficient, the equivalent yaw damping coefficient and the equivalent yaw inertia; determining a rear wheel deflection angle by using the vehicle side slip angle function, the vehicle yaw angle function and the vehicle steering input information; and controlling the rear wheel deflection angle based on the target steering control mode. According to the invention, the technical problems of low vehicle response speed and poor operation stability during vehicle steering of the long-wheelbase vehicle in the prior art are solved.

    本发明公开了一种车辆后轮转向控制方法、装置、存储介质及电子装置。其中,该方法包括:获取车辆转向输入信息;基于车辆二自由度模型确定车辆质心侧偏角函数,并根据前轮转向动态增益系数、等效横摆阻尼系数和等效横摆惯量确定车辆横摆角函数;利用车辆质心侧偏角函数、车辆横摆角函数和车辆转向输入信息确定后轮偏转角度;基于目标转向控制方式对后轮偏转角度进行控制。本发明解决了相关技术中长轴距车辆在进行车辆转向时的车辆响应速度低、操作稳定性差的技术问题。
