Abstract

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.

Description

technical field [0001] The invention relates to a wire-controlled system for an automatic driving chassis of a mining dump truck. Background technique [0002] Because the working principle of a large dump truck is completely different from that of a passenger car, when the vehicle is running, only the power circuit part involves multiple technologies such as power generation, rectification, inverter, and frequency conversion; [0003] The electronic control system is designed for human-driven vehicles and is a closed system that does not provide interfaces related to wire control. If you want to carry out the transformation of automatic control, you need to be proficient in the control principle and circuit of the whole vehicle, otherwise it will not be possible. In addition, this type of vehicle is only used in large-scale open-pit mines, so the number of personnel for use, development, and maintenance is very scarce. As a result, there has been no solution for wire contr...
