Title:
WORK VEHICLE CONTROL SYSTEM, CONTROL METHOD, AND WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/021348
Kind Code:
A1
Abstract:
This work vehicle control system is equipped with a current topography acquisition device, a storage device, and a controller. The current topography acquisition device acquires current topography information indicating the current topography of the site where work is to be performed. The storage device stores design topography information indicating the final design topography for the site where work is to be performed. The controller acquires the current topography information from the current topography acquisition device. The controller acquires the design topography information from the storage device. The controller generates a command signal for moving a work machine along a first trajectory that follows the slope of the current topography, and along a second trajectory that is located above the current topography and below the final design topography at the front end of the first trajectory.
