Abstract: An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.

Abstract: Provided is a display system, which makes it easy for an operator to accurately grasp a traveling situation of a work vehicle. A front camera captures an excavating blade and topography in front of a crawler dozer. A rear camera captures a fuel tank and a ripper apparatus, and a topography behind the crawler dozer. A display image displayed on a monitor is generated by arranging a front image captured by the front camera and a rear image captured by the rear camera so that the excavating blade in the front image may face the fuel tank in the rear image.

Abstract: A bulldozer includes a blade disposed in front of a vehicle body. First and second cameras are disposed to the left and right of the vehicle body, respectively. A first optical axis of the first camera faces forward and downward. The first camera overlaps a left crawler belt as seen in a plan view of the bulldozer and is arranged to capture a first image of a gap between a lower edge of the blade and the left crawler belt. A second optical axis of the second camera faces forward and downward. The second camera overlaps a right crawler belt as seen in a plan view of the bulldozer and is arranged to capture a second image of a gap between a lower edge of the blade and the right crawler belt. A display is configured to display the first and second images side-by-side.

Abstract: A bulldozer has a protective structure. The protective structure includes a left pillar portion, a right pillar portion, and a beam portion. The left pillar portion is disposed to the left of a cab and extends in the up-down direction. The right pillar portion is disposed to the right of the cab and extends in the up-down direction. The beam portion is disposed above the cab and couples the left pillar portion and the right pillar portion. A first camera is attached to the left pillar portion and is disposed so that a first optical axis faces forward and downward. A second camera is attached to the right pillar portion and is disposed so that a second optical axis faces forward and downward.
