Problems solved by technology

[0002] At present, traditional road rollers rely entirely on operators for construction, and some schools realize unmanned road rollers in the laboratory only based on satellite control in a conventional environment. The control adopts the traditional PID adjustment and attitude information based on satellite positioning. There is no adjustment for the collaborative operation of the tracking fleet, and it is all based on experience. There is no collection and recognition feedback for the actual state and construction scene.

Abstract

The invention discloses a road roller and a controller, a control method and system thereof. The control method of the road roller comprises the following steps of: obtaining surrounding environment information of the road roller; determining the working condition of the road roller corresponding to surrounding environment information; obtaining vehicle attitude information and vehicle location information; generating path planning information according to the surrounding environment information, the vehicle attitude information, and the vehicle location information; and performing motion control on the road roller according to the path planning information and sensor information inside the road roller. According to the road roller and the controller, the control method and system thereof,multi-sensor complementary fusion technology is used to detect and analyze the surrounding environment through signal acquisition, the control precision, the self-learning ability, and the self-adaptive ability of the unmanned road roller are improved, and the rapid and smooth starting steering precision and speed of the unmanned road roller under various working conditions can be greatly improved.

Description

technical field [0001] The invention relates to the field of road rollers, in particular to a road roller and its controller, control method and system. Background technique [0002] At present, traditional road rollers rely entirely on operators for construction, and some schools realize unmanned road rollers in the laboratory only based on satellite control in a conventional environment. The control adopts the traditional PID adjustment and the attitude information based on satellite positioning. There is no adjustment for the collaborative operation of the tracking fleet, and it is all based on experience. There is no collection and recognition feedback for the actual state and construction scene. [0003] The walking system is controlled by the conventional PID control method, and the PID controller is a regulator widely used. The control system is composed of the controlled object and the traditional PID controller. The PID controller is a linear controller based on pr...
