AI Technical Summary

Technical Problem

Conventional methods require manual recreation of road curves using CAD for vibratory rollers, which is time-consuming and inefficient for automated construction on curved surfaces.

Method used

A travel path generation device that acquires linear data of roads or rivers, generating travel paths with straight lines, circular curves, and transition curves, allowing for automated construction machinery to follow the alignment without manual recreation, and includes a lane change path generation unit for smooth lane transitions.

Benefits of technology

Enables efficient generation of travel paths suitable for automated construction, reducing time and cost by allowing construction machinery to follow existing road or river alignments, with smoother travel through sharper inner lanes.

Abstract

To provide a travel route generation device capable of easily creating a travel route having a curve, a travel route generation method, a travel route generation program, and an automation implementation system.SOLUTION: A travel route generation device 2A for generating a travel route of a construction machine comprises: a linear data acquisition unit 21 which acquires linear data of a road or a river; and a travel route generation unit 23 which generates the travel route on the basis of the linear data. The linear data contains a reference line shape indicative of a reference line in an extension direction of the road or the river. The travel route is represented by a set of coordinates at a passing point through which the construction machine passes. The travel route generation unit 23 has: a passing reference point setting unit 24 which sets a passing reference point at a prescribed interval on the reference line; a lane generation unit 25 which generates one or more lanes parallel to the reference line shape; and a passing point generation unit 26 which generates a pass point in a position on a lane corresponding to the passing reference point.SELECTED DRAWING: Figure 5
