Embodiment Construction
[0057] An anti-rollover control system and control method for transport vehicles in mining areas proposed by the present invention will be further described in detail with reference to the accompanying drawings.
[0058] The invention provides an anti-rollover control system for transport vehicles in mining areas such as figure 1 As shown, the control system mainly includes four logic layers: external state perception layer, rollover model real-time calculation layer, vehicle anti-rollover decision-making layer and anti-rollover execution layer. The anti-rollover control method for transport vehicles in mining areas is especially suitable for transport vehicles in mining areas that have integrated an unmanned driving system.
[0059] The external state perception layer includes steering wheel angle sensor, body roll angle sensor, lateral acceleration sensor, vehicle speed sensor and vehicle camera. Among them, the real-time body inclination data and lateral (lateral) accelera...

The invention relates to an anti-rollover control system for a mining area transport vehicle and a control method of the anti-rollover control system. The control system comprises an external state sensing layer, a rollover model real-time calculation layer, a vehicle anti-rollover decision layer and an anti-rollover execution layer. The external state sensing layer comprises a steering wheel angle sensor, a vehicle body roll angle sensor, a transverse acceleration sensor, a vehicle speed sensor and a vehicle-mounted camera. The rollover model real-time calculation layer comprises a working condition identification module and a rollover model index calculation module. The vehicle anti-rollover decision layer comprises an emergency decision module, a rollover index prediction module and ananti-rollover decision module. The anti-rollover execution layer comprises an active steering control module and an execution mechanism, and a differential brake control model and an execution mechanism. According to the control method based on the system, vehicle driving working conditions are partitioned, proper rollover indexes are selected and compared with a threshold value, emergency decisions or anti-rollover decisions are made according to different results, and the execution layer is controlled to control a vehicle through the decisions.
Description
technical field [0001] The invention relates to the field of active safety control of vehicles, and more specifically, relates to a machine control method of an anti-rollover control system for transport vehicles in mining areas. Background technique [0002] With the rapid development of the automobile industry, the number of accidents in the field of road transportation has increased, resulting in huge property losses and casualties. Among them, vehicle rollover is a high-occurrence and dangerous accident of transport vehicles in mining areas, and transport vehicles in mining areas are especially prone to rollover due to their high center of gravity after loading minerals. Relevant literature shows that if an alarm message can be issued to remind the driver or take the necessary active anti-rollover behavior 1 second before a potential vehicle rollover accident occurs, about 90% of traffic accidents can be avoided to a certain extent. 1 second in advance, the rollover acc...
