Title:
MINING VEHICLE AUTONOMOUS TRAVEL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/075577
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a mining vehicle autonomous travel system which, if a non-detected region occurs in a region to be detected by means of an external environment detection sensor, is capable of suppressing a deterioration in the work efficiency of a mining vehicle by appropriately addressing the cause of the non-detected region. To this end, a controller: associates a three-dimensional point cloud acquired by the external environment detection sensor with a point cloud map; calculates a change in position of the external environment detection sensor on the basis of a measurement result from a vehicle position measuring sensor; if a three-dimensional point cloud that is to be acquired by the external environment detection sensor could not be acquired, extracts a region of the point cloud map as a non-detected region; determines a cause of the non-detected region on the basis of whether the position of the non-detected region in the point cloud map changes in accordance with a change in position of the vehicle; and sets an operation of the vehicle in accordance with the cause of the non-detected region.
