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 which is a target topography of the work target. The controller acquires the actual topography information from the actual topography acquisition device. The controller acquires the design topography information from the storage device. The controller generates a command signal to move the work implement along a first locus that follows a slope of the actual topography, and a second locus positioned above the actual topography and below the final design topography in front of the first locus.

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. Inclination angles of at least two of the intermediate design surfaces differ from each other.

Abstract: A work vehicle control system 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, which indicates an actual topography of a work target. The storage device stores design topography information, which indicates a final design topography of the work target. 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, the design topography information from the storage device, and the soil amount signal from the soil amount acquisition device. The controller determines an intermediate design topography positioned above the actual topography and below the final design topography in accordance with the held soil amount. The controller generates a command signal to move the work implement based on the intermediate design topography.

Abstract: A bulldozer includes a blade pivotably attached to a vehicle body, a blade operation lever, and a blade control section. The blade operation lever outputs a lowering instruction signal, a holding instruction signal, and a raising instruction signal for the blade. The blade control section controls a height of the blade according the signal input. The blade control section can lower the blade to a predetermined position when the lowering instruction signal and the holding instruction signal are input in order after a transmission has been switched from a state, which is different from an advancing state, to the advancing state. The blade control section can raise the blade to a predetermined position when the raising instruction signal and the holding instruction signal are input in order after a transmission has been switched from a state, which is different from a reversing state, to the reversing state.
