A method for anti-rollover control of transport vehicles in mining areas

Abstract

The invention relates to an anti-rollover control system and control method for transport vehicles in mining areas. The control system includes an external state perception layer, a rollover model real-time calculation layer, a vehicle anti-rollover decision-making layer, and an anti-rollover execution layer; The external state perception layer includes a steering wheel angle sensor, a vehicle body roll angle sensor, a lateral acceleration sensor, a vehicle speed sensor, and an on-board camera; the real-time calculation layer of the rollover model includes a working condition identification module and a rollover model index calculation module; The rollover decision-making layer includes an emergency decision-making module, a rollover index prediction module, and an anti-rollover decision-making module; the anti-rollover execution layer includes an active steering control module and an actuator, a differential braking control model, and an actuator; The control method divides the driving conditions of the vehicle, selects the appropriate rollover index, compares it with the threshold, makes emergency decisions or anti-rollover decisions according to different results, and controls the vehicle through the above-mentioned decision-making control execution layer.

Description

Technical field [0001] The present invention relates to the field of vehicle active safety control, and more particularly to a mechanical control method of a mine transport vehicle anti-side flood control system. Background technique [0002] With the rapid development of the automotive industry, the number of accidents in road transportation is increasing, causing huge property losses and casualties. Among them, the side turning on the vehicle is a high and dangerous accident of the transportation vehicle in the mining area. The mine transport vehicles are particularly prone to rollover due to the higher center of gravity after loading minerals. Relevant literatures show that if the alarm information can be issued to alert the driver or take the necessary active anti-side turning to a certain extent, about 90% of traffic accidents can be avoided. 1 second in advance, the side turns may be completely avoided. [0003] Currently, the study of vehicle side turning machinery and rel...
