摘要： A display system includes a work vehicle, a first camera, a computation device, and a display device. The first camera is attached to one side portion of the work vehicle. The first camera has an optical axis inclined downward with respect to a horizontal direction. The first camera captures a first image including a surrounding environment of the work vehicle and a first vehicle body portion. The computation device generates a display image from the first image. The display image includes a surrounding image that depicts the surrounding environment of the work vehicle in a bird's-eye view, and a vehicle image. The vehicle image may combine a vehicle model depicted in the work vehicle and an image of the first vehicle body portion captured by the first camera, or may be an image of the first vehicle body portion. The display device displays the display image.

摘要： The camera captures an image of a surrounding environment of a work vehicle and outputs image data indicative of the image. The shape sensor measures a three-dimensional shape of the surrounding environment and outputs 3D shape data indicative of the three-dimensional shape. A controller acquires the image data and the 3D shape data. The controller generates a three-dimensional projection model based on the 3D shape data. The three-dimensional projection model portrays the three-dimensional shape of the surrounding environment. The image is projected onto the three-dimensional projection model based on the image data, thereby generating display image data that represents a display image of the surrounding environment of the work vehicle.

摘要： At least a portion of a first target design topography is positioned below an actual topography. At least a portion of a second target design topography is positioned below the actual topography and is inclined with respect to the first target design topography. A controller generates a command signal to operate a work implement according to the first target design topography in an area where the first target design topography is positioned above the second target design topography. The controller generates a command signal to operate the work implement according to the second target design topography in an area where the second target design topography is positioned above the first target design topography.

摘要： When left and right steering levers are both operated and the operation amount of the left lever is larger than that of the right lever, a controller calculates a correction left operation amount of the left lever according to the operation amount of the right lever, and controls a left steering clutch so as to cause a vehicle body to turn toward the left in accordance with the correction left operation amount. When left and right steering levers are both operated and the operation amount of the right lever is larger than that of the left lever, the controller calculates a correction right operation amount of the right lever according to the operation amount of the left lever, and controls a right steering clutch so as to cause the vehicle body to turn toward the right in accordance with the correction right operation amount.

摘要： A control system for a work vehicle includes a controller. The controller determines a work zone at a work site. The controller determines a target design topography at least partially positioned below an actual topography at the work site. The controller specifies a non-work zone. The non-work zone is a portion in which the actual topography is positioned below the target design topography in the work zone. The controller modifies the work zone based on the non-work zone. The controller generates a command signal to operate a work implement of the work vehicle according to the modified work zone and the target design topography.

摘要： 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 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 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.

摘要： A radiator grill is mounted on a work vehicle and includes a frame and a plate member. The plate member is supported by the frame and having a plurality of through-holes aligned in a first direction and a second direction orthogonal to the first direction. Each of the through-holes has a pair of circular parts aligned in the first direction, and an interconnecting part having a width in the second direction that is smaller than diameters of the circular parts, the interconnecting part interconnecting the circular parts. The through-holes are disposed alternately so that one of the circular parts of one of two adjacent ones of the through-holes adjacent to each other in the second direction is aligned with the interconnecting part of the other of the two adjacent ones of the through-holes in the second direction.

摘要： A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller acquires an end position and a target distance of work performed by a work vehicle. The controller determines, as a start position, a position that is away from the end position by the target distance. The controller generates a command signal to start work from the start position toward the end position and to operate the work implement according to a target design topography. The controller modifies the target distance based on a result of the work.

摘要： 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.
