Abstract: A control system for a work vehicle includes an actual topography acquisition device, a storage device, a soil amount acquisition device, and a controller. The actual topography acquisition device acquires actual topography information indicating an actual topography of a work target. The storage device stores design topography information indicating a final design topography. The soil amount acquisition device generates a soil amount signal indicating a held soil amount of the work implement. The controller acquires the actual topography information from the actual topography acquisition device and acquires the design topography information from the storage device. The controller generates a command signal for moving the work implement at position that is between the actual topography and the final design topography and is a predetermined distance above the actual topography. The controller acquires the soil amount signal and changes the predetermined distance based on the held soil amount.

Abstract: A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller obtains first topographical data indicative of a topography of a work target before filling work. The controller obtains blade tip position data indicative of a blade tip position of the work implement during the filling work. The controller obtains second topographical data indicative of a compacted topography after the filling work. The controller determines a compression rate of the work target from the first topographical data, the blade tip position data, and the second topographical data.

Abstract: A work vehicle control system includes an actual topography acquisition device, a storage device, and a controller. The actual topography acquisition device acquires actual topography information, which indicates an actual topography of a work target. The storage device stores design topography information, which indicates a final design topography that is a target topography of the work target. The controller acquires the actual topography information from the actual topography acquisition device, and the design topography information from the storage device. The controller determines an intermediate design topography positioned above the actual topography and below the final design topography. The controller generates a command signal to move the work implement based on the intermediate design topography. The intermediate design topography includes a plurality of intermediate design surfaces divided in the traveling direction of the work vehicle.

Abstract: A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move a work implement of the work vehicle along the design surface. The controller determines if slip of the work vehicle has occurred. Upon determining that slip has occurred, the controller changes the design surface to a position equal to or higher than a blade tip position of the work implement when the slip occurred.
