The invention provides a vehicle control method, device and equipment and a readable storage medium, and the vehicle control method comprises the steps: when a vehicle runs on a split road surface and is in an emergency braking working condition or a rapid acceleration working condition, calculating a target rotation angle of a rear wheel of the vehicle; and the target turning angle is output to a rear wheel steering system so that the rear wheel steering system can control rear wheel steering according to the target turning angle. By means of the method and device, when the vehicle runs on the split road surface and conducts emergency braking or rapid acceleration, due to the fact that the road surface adhesive force provided by the high attachment side is different from the road surface adhesive force provided by the low attachment side, the vehicle deflects, namely the vehicle has the risk of instability, the target turning angle of the rear wheels of the vehicle is obtained through calculation, and the target turning angle is output to the rear wheel steering system; the yaw torque generated by deflection of the vehicle on the split road is balanced, so that the stability of the vehicle can be improved.
本发明提供一种车辆控制方法、装置、设备及可读存储介质,车辆控制方法包括:当车辆行驶在对开路面,且处于紧急制动工况或急加速工况时,计算得到车辆后轮的目标转角;将目标转角输出至后轮转向系统,以供后轮转向系统根据目标转角控制后轮转向。通过本发明,当车辆行驶在对开路面,在进行紧急制动或急加速时,由于高附侧和低附侧所提供的路面附着力不同,会使车辆发生偏转,即车辆会有失稳的风险,通过计算得到车辆后轮的目标转角,将目标转角输出至后轮转向系统,以平衡对开路面车辆发生偏转所产生的横摆扭矩,从而能够提升车辆的稳定性。
