Abstract
A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller obtains actual topography data indicative of an actual topography of a work site. The controller determines a target depth. The controller obtains positions of a plurality of division points positioned on the actual topography based on the actual topography data. The controller determines a plurality of reference points by displacing the plurality of division points in a vertical direction by the target depth. The controller determines a target design topography based on the plurality of reference points. The controller generates a command signal to operate the work implement in accordance with the target design topography.
