The embodiment of the invention provides a method, system and equipment for controlling vehicle steering and a medium, and the method comprises the steps: determining whether to activate a target steering function or not according to the state information of a vehicle; under the condition that the target steering function is activated, a steering outer side rear wheel and a steering inner side rear wheel are determined according to steering of a steering wheel; determining a forward target torque of a front axle according to the wheel speed of the front wheel, and determining a reverse target torque of a rear axle according to the wheel speed of the rear wheel on the steering inner side; and controlling a front axle driving motor to output a forward target torque, controlling a rear axle driving motor to output a reverse target torque, and braking a steering outer side rear wheel through a braking system according to the wheel speed of the steering outer side rear wheel so as to assist the vehicle in steering. The invention aims to reduce the steering radius of the vehicle so as to reduce the steering difficulty of the vehicle in a small-radius steering scene.

    本申请实施例提供一种控制车辆转向的方法、系统、设备及介质,方法包括:根据车辆的状态信息,确定是否激活目标转向功能;在目标转向功能激活的情况下,根据方向盘的转向,确定转向外侧后轮和转向内侧后轮;根据前轮轮速,确定前轴的正向目标扭矩,以及,根据转向内侧后轮轮速,确定后轴的反向目标扭矩;控制前桥驱动电机输出正向目标扭矩,以及控制后桥驱动电机输出反向目标扭矩,以及根据转向外侧后轮轮速,通过制动系统对转向外侧后轮进行制动,以辅助车辆进行转向。旨在减小车辆转向半径,以降低车辆在小半径转向场景下的转向难度。
