AI Technical Summary
During long-distance continuous downhill driving, the mechanical braking system of unmanned mining trucks is prone to overheating and wear. There is a lack of retarder-assisted braking schemes adapted to the autonomous control logic of unmanned driving, which makes it impossible to achieve coordinated speed regulation control between multi-stage retarders and mechanical braking systems, thus posing safety hazards.
When the unmanned mining truck's operating scenario is detected as a preset effective scenario, the compensation coefficients for the retarder gear command and the mechanical braking command are determined, the mechanical braking command is obtained and corrected, and the coordinated speed regulation control of the retarder and the mechanical braking system is realized.
It achieves automatic control of the retarder gear, avoids overheating and brake force decay of mechanical brakes, improves the accuracy, safety and system reliability of downhill speed control, extends the service life of the braking system and reduces operation and maintenance costs.
