The invention discloses a drive-by-wire steering system of a mining dump truck. The drive-by-wire steering system comprises a touch feedback device, a steering control valve, a steering mechanism, a steering angle sensor, a vehicle speed sensor and a controller. The touch feedback device is arranged on the lower portion of the steering wheel, connected with the controller through a CAN bus and used for detecting the rotation angle of the steering wheel and sending a generated rotation angle signal to the controller; the steering control valve is connected with the signal input end of the steering mechanism through a signal line and connected with the controller through a CAN bus, and an output port of the steering control valve is connected with the steering mechanism through a pipeline, receives control signals of the controller and outputs hydraulic flow to the steering mechanism. And the controller forms a control signal according to the deflection angle signal and the driving speed signal. The invention further discloses a mining dump truck and a steer-by-wire method. A hydraulic physical pipeline between the steering wheel and the steering valve is omitted, and steering is achieved in a drive-by-wire mode.

    本发明公开了一种矿用自卸车线控转向系统,包括:触感反馈装置、转向控制阀、转向机构、转角传感器、车速传感器、控制器;触感反馈装置,设置在方向盘下部,通过CAN总线与控制器连接,用于检测方向盘的转动角度,将产生的转动角度信号发送给控制器;转向控制阀,通过信号线与转向机构的信号输入端连接,通过CAN总线与控制器连接,输出口通过管路连接转向机构,接收控制器的控制信号,输出液压流量到转向机构;控制器,根据偏转角度信号、行驶速度信号形成控制信号。本发明还公开了一种矿用自卸车及线控转向方法。本发明取消了方向盘与转向阀之间的液压物理管路,通过线控方式实现转向。
