Problems solved by technology
[0004] In the existing technical solutions, it is mainly aimed at manned vehicles, and the method of directly setting a single threshold upper limit has certain limitations. The set threshold may not be able to meet various gear upper limit restrictions. At the same time, the gear limit function It is necessary to add a manual switch for control, which is not feasible for unmanned vehicles

The invention provides a control system for the gear restriction of a driverless mine car, and a control method. The above control system comprises an automatic gearbox control unit, a first revolvingspeed sensor, an engine management system, a vehicle control unit, an electronic braking system, a second revolving speed sensor, an intelligent driving controller, a decision making and planning system and a perception and positioning system. Through the information feedback of the first revolving speed sensor, the second revolving speed sensor, the engine management system and the like, in an operating and driving process of the driverless mine car, the state of the mine car is monitored in real time, the highest gear of the mine car can be subjected to real-time restriction control according to a car state and a driving scene or a driving working condition, the safety performance of the driving of the driverless mine car is improved on a premise that the normal driving of the car is guaranteed so as to be suitable for complex and hostile driving environments of a mine lot and the driving differences of the no load and the heavy load of the mine car, certain driving safety hidden dangers are avoided, and the safety allowable redundancy of the driverless system of the mine car is improved.
Description
technical field [0001] The invention belongs to the technical field of intelligent control of unmanned driving, and in particular relates to a control system and a control method for gear limit of unmanned mining vehicles. Background technique [0002] The key technology of unmanned driving involves many technical fields such as environment perception, high-precision positioning, decision-making planning, executive control, etc. Among them, vehicle motion control, as the vehicle-end execution layer of the intelligent driving vehicle system, is directly related to the final realization of the intelligent driving function. . Vehicle motion control is the core part of executive control, generally divided into vehicle longitudinal control and lateral control. Longitudinal control mainly controls the accelerator opening (electronic throttle opening) and braking degree of the vehicle to achieve acceleration and deceleration of the vehicle, thereby controlling the speed of the veh...
