Title:
ADAPTIVE CONTROL SYSTEM AND METHOD FOR SLOPE-CLIMBING TORQUE OF MINING MECHANICAL-TRANSMISSION DUMPER
Document Type and Number:
WIPO Patent Application WO/2024/088429
Kind Code:
A1
Abstract:
Disclosed in the present invention are an adaptive control system and method for the slope-climbing torque of a mining mechanical-transmission dumper. The method comprises the following steps: acquiring and analyzing signal data of a tilt angle sensor and of an accelerator pedal, and determining whether a dumper is in a slope-climbing state; if the dumper is in a slope-climbing state, then acquiring and analyzing signal data of suspension pressure sensors and a rotation speed sensor, and performing calculation to obtain traction forces and resistances which correspond to different gear speed ratios of a gearbox; if a traction force corresponding to the highest gear speed ratio of the gearbox is greater than or equal to a resistance corresponding thereto, then not entering a slope-climbing torque adaptive-control mode, and not sending a gear-limiting instruction to a gearbox controller; and if the traction force corresponding to the highest gear speed ratio of the gearbox is less than the resistance corresponding thereto, then entering the slope-climbing torque adaptive-control mode, and sending a gear-limiting instruction to the gearbox controller. The present invention realizes adaptive control over the slope-climbing torque of a dumper, effectively eliminates the effect of improper manual operations on the power performance, the transportation efficiency and the driving safety of a vehicle, and has great practicability.
