The invention discloses an automatic driving chassis drive-by-wire system of a mining dump truck. A robot is additionally arranged in a cab to carry out human simulation operation, and the robot operates a steering wheel, an accelerator, a brake and other mechanisms in a physical control mode. According to the scheme, the reliability is poor, the control precision is poor, the failure rate is high, and a direct control scheme does not occur. The system comprises a controller, a traction and electric braking control circuit, a gear control circuit, a truck electric control communication circuit, a lifting control circuit, an engine rotating speed and wheel rotating speed circuit and a steering system and engine communication circuit. The drive-by-wire system is used for drive-by-wire of the automatic driving chassis of the mining dump truck.
