Auxiliary steering system based on differential braking and control method

The invention discloses an auxiliary steering system based on differential braking and a control method. The auxiliary steering system comprises an electronic hydraulic braking system assembly, a plunger pump clutch device, a plunger pump high-pressure loop assembly, a steering wheel angular displacement sensor, a vehicle speed sensor, an upper-layer controller and a main controller. According to the invention, the stability of the vehicle can be ensured when the vehicle steers during high-speed driving, and the braking energy of the vehicle during differential braking is further utilized for auxiliary braking, so that the energy consumption of the vehicle is reduced, and the driving range of the vehicle is further increased. 本发明公开了一种基于差动制动的辅助转向系统及控制方法，包括：电子液压制动系统总成、柱塞泵离合装置、柱塞泵高压回路总成、方向盘角位移传感器、车速传感器、上层控制器及主控制器；本发明能够使得车辆在高速行驶转向时能够保证车辆的稳定性，而且车辆在差动制动时的制动能量进一步得到利用，进行辅助制动，减少了车辆能源的消耗，进一步提升了车辆的续驶里程。
