The invention relates to a drive-by-wire full-hydraulic steering system for an unmanned mining vehicle. A laser radar sensor, an angle sensor and a torque and angle sensor are connected to an electronic control unit, the electronic control unit, the electronic control unit is connected with a drive-by-wire steering motor, and the drive-by-wire steering motor is connected with the full-hydraulic steering system; the laser radar sensor is arranged at the front end of the frame, front obstacles in the running process of the vehicle are recognized through the laser radar sensor, the laser radar sensor transmits sensed position information and obstacle information to the electronic control unit, and the electronic control unit controls the steering motor to adjust the steering angle. The adjustment of a driving route and the avoidance of obstacles are realized; the torque and angle sensor is arranged on the steering column of the full-hydraulic steering system; the torque and angle sensor collects the rotation angle and torque of a steering wheel, and the angle sensor is arranged on a vehicle front axle close to wheels, converts the rotation angle of the wheels in the driving direction into an electric quantity signal and transmits the electric quantity signal to the electronic control unit.

    本发明涉及无人驾驶矿用车用的线控全液压转向系统,激光雷达传感器、角度传感器、所述转矩转角传感器均连接至电子控制单元,电子控制单元与线控转向电机相连,线控转向电机与全液压转向系统连接;激光雷达传感器设置在车架前端,通过激光雷达传感器识别车辆行驶过程中前方障碍物,激光雷达传感器将感知到的位置信息和障碍信息传输至电子控制单元,通过电子控制单元控制线控转向电机调整转向角度,实现行驶路线的调整和障碍物的规避;转矩转角传感器设置在全液压转向系统的转向管柱;转矩转角传感器采集方向盘的转动角度和转矩,角度传感器布置在靠近车轮位置的车辆前桥上,将沿着行驶方向的车轮转动角度转换为电量信号传输至电子控制单元。
