The invention relates to the technical field of automobile driving, and discloses a vehicle steering control system and method, a controller, a vehicle and a storage medium, and the system comprises a vehicle stability controller which obtains the actual vehicle speed of the vehicle in real time, converts a target yaw torque into a steering vector torque when the actual vehicle speed exceeds a preset speed threshold value, and outputs the steering vector torque to the vehicle stability controller; the steering vector torque is sent to a vehicle dynamic domain calculation unit; and the vehicle dynamic domain calculation unit is used for controlling a front axle motor and a rear axle motor of the vehicle according to the steering vector torque to carry out steering control on the vehicle. Therefore, when the actual vehicle speed of the vehicle exceeds the preset speed threshold value, the vehicle dynamic domain calculation unit controls the front and rear axle motors of the vehicle according to the steering vector torque to perform steering control on the vehicle, so that the problem that the steering sensitivity of a rear wheel steering controller RWS is low when the vehicle runs at a high speed is solved, and the steering accuracy of the vehicle is improved. And the stability of the vehicle steering control system during high-speed driving of the vehicle is improved.
本发明涉及汽车驾驶技术领域,公开了一种车辆转向控制系统、方法、控制器、车辆及存储介质,包括:车辆稳定控制器,实时获取车辆的实际车速,在所述实际车速超过预设的速度阈值时,将目标横摆扭矩转换为转向矢量扭矩,并将所述转向矢量扭矩发送到车辆动态域计算单元;所述车辆动态域计算单元,根据所述转向矢量扭矩控制所述车辆的前后轴电机对所述车辆进行转向控制。可见,本发明在车辆的实际车速超过预设的速度阈值时,通过车辆动态域计算单元根据转向矢量扭矩控制车辆的前后轴电机对车辆进行转向控制,避免了车辆在高速行驶时,后轮转向控制器RWS转向灵敏度低的问题,有利于提高车辆在高速行驶时车辆转向控制系统的稳定性。
