The embodiment of the invention provides a steering auxiliary control method, system and device and a medium, and the method comprises the steps: determining whether to start a steering auxiliary function or not according to an obtained target signal; under the condition that the steering auxiliary function is started, according to the driving terrain, a front axle target deflection torque and a rear axle target deflection torque are determined; according to the front axle target deflection torque, a front axle driving motor is controlled to apply corresponding forward driving torque to front wheels of the vehicle and apply corresponding braking torque to steering inner side front wheels of the vehicle, so that a front axle of the vehicle is controlled to obtain the front axle target deflection torque; and according to the rear axle target deflection torque, a rear axle driving motor is controlled to apply corresponding reverse driving torque to rear wheels of the vehicle and apply corresponding braking torque to steering outer side rear wheels of the vehicle, so that a rear axle of the vehicle is controlled to obtain the rear axle target deflection torque. The steering radius of the vehicle is reduced, and the steering difficulty of the vehicle is lowered.

    本申请实施例提供一种转向辅助控制的方法、系统、设备及介质,方法包括:根据获取的目标信号,确定是否开启转向辅助功能;在转向辅助功能开启的情况下,根据行驶地形,确定前轴目标偏转扭矩和后轴目标偏转扭矩;根据前轴目标偏转扭矩,控制前桥驱动电机向车辆的前轮施加对应的正向驱动扭矩和向车辆的转向内侧前轮施加对应的制动扭矩,以控制车辆的前轴获得前轴目标偏转扭矩;根据后轴目标偏转扭矩,控制后桥驱动电机向车辆的后轮施加对应的反向驱动扭矩和向车辆的转向外侧后轮施加对应的制动扭矩,以控制车辆的后轴获得后轴目标偏转扭矩。旨在减小车辆转向半径,降低车辆的转向难度。
