The invention relates to a power difference steering system of a four-wheel independent drive vehicle and a control method, and the power difference steering system comprises four wheels, four drive mechanisms, four controllers and a master controller; the four driving mechanisms are respectively in driving connection with the four wheels; the four controllers are connected with the four driving mechanisms correspondingly and control the four driving mechanisms correspondingly. The master controller is connected with the four controllers and controls the four controllers, and the master controller has different power difference steering control modes according to the vehicle speed. The system can independently drive the vehicle to achieve large-differential-speed steering, the steering performance is better than that of other vehicles, and the turning radius is small; center steering of the vehicle can be achieved, uniform steering of the inner side and the outer side of the vehicle can be achieved, stable steering of the vehicle in a high-speed state can be achieved, and overturning of the vehicle during high-speed steering is prevented; the steering advantage of the four-wheel independent drive vehicle is fully played, and the maneuverability, stability and safety of the vehicle are effectively improved.
本发明涉及一种四轮独立驱动车辆动力差转向系统及控制方法,其中,动力差转向系统包括:四个车轮、四个驱动机构、四个控制器和总控制器;四个驱动机构分别与四个车轮驱动连接;四个控制器分别与四个驱动机构连接,四个控制器分别控制四个驱动机构;总控制器与四个控制器连接,对四个控制器进行控制,总控制器根据车速具有不同的动力差转向控制模式。该系统能够独立驱动车辆实现大差速的转向,转向性能优于其他车辆,转弯半径小;可实现车辆中心转向、可使车辆的内外侧实现均匀转向以及可实现车辆在高速状态下的稳定转向,防止车辆高速转向时翻车;充分发挥四轮独立驱动车辆的转向优势,有效地改善车辆的操纵性、稳定性和安全性。
