The invention relates to an electric control hydraulic type vehicle steering system and method thereof. The system comprises a mechanical hydraulic power-assisted steering system, an electric controlhydraulic active steering system and a controller. The mechanical hydraulic power-assisted steering system can assist in a mechanical connecting rod to realize active steering of a front-end steeringaxle of the vehicle; the electric control hydraulic active steering system can drive a rear-end steering axle of the vehicle to steer. The controller in signal connection with an angular displacementsensor of the front-end steering axle can calculate angular displacement needed by the rear-end steering axle according to the angular displacement of the front-end steering axle and controls the electric control hydraulic active steering system to move so as to drive the rear-end steering axle to rotate by a set angle.
本发明涉及一种电控液压式车辆转向系统及方法,机械液压助力转向系统、电控液压主动转向系统和控制器。所述机械液压助力转向系统能够辅助机械连杆实现车辆的前端转向桥主动转向;所述电控液压主动转向系统能够驱动车辆的后端转向桥转向。所述控制器与前端转向桥的角位移传感器信号连接,所述控制器能够根据前端转向桥的角位移计算出后端转向桥所需的角位移,控制器控制电控液压主动转向系统运动以驱动后端转向桥转动设定的角度。
