The invention relates to a vehicle control method and device and a vehicle. The vehicle control method comprises the steps that the current target mass, the target vehicle speed, the target steering wheel turning angle, the target front axle cornering stiffness and the target rear axle cornering stiffness of the vehicle are obtained; and according to the target vehicle speed, the target mass, the target front axle cornering stiffness and the target rear axle cornering stiffness, the target ratio of the front wheel turning angle to the rear wheel turning angle of the current vehicle is determined through a preset formula, and rear wheel steering of the vehicle is controlled according to the target ratio and the target steering wheel turning angle. The accuracy and reliability of vehicle steering control can be effectively improved, so that the stability and safety of vehicle steering and driving can be effectively improved.
本公开涉及一种车辆控制方法、装置及车辆,该车辆控制方法通过获取车辆当前的目标质量、目标车速、目标方向盘转角、目标前轴侧偏刚度和目标后轴侧偏刚度;根据所述目标车速、所述目标质量、所述目标前轴侧偏刚度以及所述目标后轴侧偏刚度,通过预设公式确定当前所述车辆的前轮转角与后轮转角的目标比值,根据所述目标比值和所述目标方向盘转角控制所述车辆的后轮转向,能够有效提升车辆转向控制的准确性和可靠性,从而能够有效提升车辆转向和行驶的稳定性和安全性。
