The invention belongs to the technical field of mining dump trucks, and particularly discloses a redundant steering control system and method for an unmanned mining dump truck, and the system comprises a first steering module which is used for controlling the vehicle steering of the dump truck; the second steering module replaces the first steering module to control the vehicle steering of the dumper; the control part is used for switching the first steering module and the second steering module; the steering part is used for converting hydraulic pressure into linear thrust; the steering part outputs linear thrust and drives wheels of the dumper through the steering mechanism, so that the first steering module or the second steering module controls the wheels to swing under the condition that a steering tie rod connected with the wheels is in relative movement; compared with an electric control unit and a motor control steering system, the steering system has the advantages that no mechanical transmission mechanism is arranged between the motor and the steering column, the rotation ratio change caused by kinematic pair abrasion is avoided, the stability is better, and the occupied space is small; the power demand of the power supply is low, and only the electromagnetic coil of the driving electromagnetic valve is electrified.

    本发明属于矿用自卸车技术领域,具体公开了一种无人驾驶矿用自卸车冗余转向控制系统和方法,包括:第一转向模块,用于控制自卸车的车辆转向;第二转向模块,代替第一转向模块控制自卸车的车辆转向;控制部,用于切换第一转向模块和第二转向模块;转向部,用将液压转化为线性推力;转向部输出线性推力并通过转向机构带动自卸车的车轮,以使第一转向模块或第二转向模块在与车轮相连的转向横拉杆处于相对于移动的状况下控制车轮摆动;具有如下优点:相对于电控单元和电机控制转向系统,无电机与转向柱间的机械传动机构,不会因为运动副磨损造成转动比变化,稳定性更好,且占用空间小;电源功率需求低,仅驱动电磁阀电磁线圈通电,相对驱动电机更低。
