The invention provides a high-speed turning insufficient steering control method and device, a medium and equipment. The method comprises the steps that state parameters of a target vehicle are obtained when the target vehicle steers at a high speed; wherein the state parameters comprise dynamic parameters of the target vehicle in the running process and inherent static parameters of the target vehicle; determining a steering state of the target vehicle based on the state parameter; if the steering state shows that the steering of the target vehicle is insufficient, calculating a target slip rate of the target vehicle; calculating the target torque of the target vehicle based on the target slip rate and the longitudinal adhesive force provided for the target vehicle by the road surface; controlling the target vehicle to run based on the target torque; namely, the state parameters of the target vehicle are collected when the target vehicle turns at a high speed, whether steering is insufficient or not is judged based on the state parameters, if steering is insufficient, the target slip rate is calculated, the target torque is calculated by combining the longitudinal adhesive force provided for the target vehicle by the road surface to control the target vehicle to run stably, and therefore stability and safety are improved.

    本发明提供了一种高速过弯转向不足的控制方法、装置、介质及设备,通过在目标车辆高速转向时获取目标车辆的状态参数;其中,状态参数包括目标车辆在运行过程中的动态参数和目标车辆固有的静态参数;基于状态参数,确定目标车辆的转向状态;若转向状态表示目标车辆的转向不足,则计算目标车辆的目标滑移率;基于目标滑移率和路面提供给目标车辆的纵向附着力,计算目标车辆的目标扭矩;基于目标扭矩,控制目标车辆运行;即在目标车辆高速过弯时采集其状态参数,并基于其状态参数判断其是否为转向不足,若存在转向不足则计算目标滑移率,并结合路面提供给目标车辆的纵向附着力计算目标扭矩以控制目标车辆稳定运行,从而提高稳定性和安全性。
