Road engineering vehicle, path planning method and system of road engineering vehicle and storage medium

Abstract

The invention provides a road engineering vehicle, a path planning method and system of the road engineering vehicle,and a computer readable storage medium. According to the road engineering vehicle, the path planning method and system of the road engineering vehicle and the storage medium, the road design data, coordinate information and course angles of the road engineering vehicle, and technological parameters of the road engineering vehicles are obtained, so that a construction region range can be determined according to a road left line and a road right line of a to-be-laid road; the path width of each road engineering vehicle and the relative distance between the adjacent road engineering vehicles are determined according to process parameters, and the initial position information and the initial advancing direction of each road engineering vehicle are determined according to the coordinate information and the course angles of the road engineering vehicle, so that the driving path of each road engineering vehicle is accurately determined; and therefore, accurate intelligent path planning is achieved, automatic road laying is achieved, the construction efficiency and precision can be improved, and the labor cost and the requirement for professional drivers can be greatly reduced.

Description

technical field [0001] The present application relates to the technical field of road engineering, in particular to a road engineering vehicle and its route planning method, system and computer-readable storage medium. Background technique [0002] Road engineering vehicles (such as paver, road roller, milling machine, grader, etc.) are usually used in multiple joint operations, and it is necessary to accurately calculate the driving path of each road engineering vehicle, so as to guide unmanned paving and Accurate construction is completed through initial pressing operations. In the past manual paving and compaction process, because people cannot perceive the precise position of road construction vehicles on the road design drawing, the path of actual road construction vehicles is not smooth enough. In addition, in the past, when a fleet of road construction vehicles was composed of multiple road construction vehicles in parallel construction, the maintenance of the overla...

Problems solved by technology

In the past manual paving and compaction process, because people cannot perceive the precise position of the road engineering vehicles on the road design drawing, the path of the actual road engineering vehicles is not smooth enough

In addition, in the past, when a fleet of road construction vehicles was composed of multiple road construction vehicles in parallel construction, the maintenance of the overlapping distance of adjacent road construction vehicles was mainly completed by the driver's experience, and it was difficult to achieve the effect of continuous and accurate lapping. Manual paving and rolling The longer, the greater the cumulative deviation

Therefore, it is difficult for road construction vehicles driven by humans to achieve the effect of continuous and precise driving
