The invention discloses a vehicle rear wheel steering control method and device.The vehicle rear wheel steering control method can be applied to the technical field of vehicle control, and the method comprises the steps that in response to a traction force control instruction, the road surface type of the current driving road surface of a target vehicle is recognized, and a road surface type recognition result is obtained; when the road surface type identification result indicates that the road surface is a target type road surface, determining a target steering direction based on the direction of a target side wheel of the target vehicle relative to the target vehicle in the horizontal direction; judging whether the driving instability degree of the target vehicle reaches a preset instability degree or not based on the target steering direction and the current steering wheel turning angle; when the driving instability degree reaches the preset instability degree, based on the target steering direction and the basic steering angle, the target steering angle of the target vehicle rear wheels at the current control moment is determined; and controlling rear wheel steering of the target vehicle according to a preset duration based on the target turning angle. According to the invention, the acceleration performance of the vehicle can be improved while the vehicle is kept stable on the split road surface.
本申请公开了车辆后轮转向控制方法及装置,其中,车辆后轮转向控制方法可应用于车辆控制技术领域,该方法包括:响应于牵引力控制指令,对目标车辆当前行驶路面的路面类型进行识别,得到路面类型识别结果;在路面类型识别结果指示为目标类型路面时,基于目标车辆的目标侧车轮在水平方向上相对于目标车辆的方向,确定目标转向;基于目标转向和当前方向盘转角,判断目标车辆的行驶不稳定程度是否达到预设不稳定程度;在行驶不稳定程度达到预设不稳定程度时,基于目标转向和基础转角,确定当前控制时刻目标车辆后轮的目标转角;基于目标转角,按照预设时长控制目标车辆的后轮转向。本申请能够使车辆在对开路面上保持稳定的同时,提高车辆的加速性能。
