Abstract: A work vehicle includes: a display device provided in a cab and configured to display work assistance information to be overlaid on an actual view of a work site; a bucket position detector configured to detect a position of a bucket; and a display controller configured to control a content to be displayed on the display device and configured to cause the work assistance information to be displayed around the bucket while causing the work assistance information to follow the movement of the bucket based on the detected position. When work assistance information becomes close to a boundary of a display area of the display device due to the movement of the bucket, the display controller is configured to cause the work assistance information to be displayed on the display device with a relative position between the work assistance information and the bucket in the display area being changed.

Abstract: A work vehicle includes: a main body having a cab; a display device provided in the cab and configured to display work assistance information to be overlaid on an actual view of a work site; a display controller configured to cause the work assistance information to be displayed on the display device; and a bucket position detector configured to detect a position of a bucket relative to the main body. The display controller is configured to cause a display position of the work assistance information on the display device to follow a movement of the bucket. The display controller is configured to change a display manner of the work assistance information on the display device based on the position detected by the bucket position detector, when the bucket is moved relative to the cab in a forward direction and a rearward direction.

Abstract: A work vehicle includes a work implement, a main body, a display device, and a display controller. To the main body, the work implement is attached, and the main body has a cab. The display device is provided in the cab and configured to overlay and thus display work assistance information on an actual view of a work site. The display controller causes the display device to display target design topography as work assistance information. When a work starts, the display controller causes the display device to display final target design topography that is achieved after the work is completed, and subsequently, switches to displaying target design topography to be achieved depending on a working step performed.

Abstract: A work vehicle includes a work implement, a main body, a bucket position detector, a display device, and a display controller. The work implement has a bucket. To the main body, the work implement is attached, and the main body has a cab. The bucket position detector detects a position of the bucket. The display device is provided in the cab and configured to overlay and thus display work assistance information on an actual view of a work site. The display controller is configured to change displaying of the work assistance information on the display device based on a distance between the position of the bucket detected by the bucket position detector and design topography.
