  • Patent number: 11208040
    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.

  • Publication number: 20210025127
    Abstract: A controller determines that a signal from an operating device represents either a normal operation to manually control a blade or a trigger operation to automatically control the blade. The controller moves the blade so that the angle of the blade is changed in accordance with the operation of the operating device when the signal from the operating device is determined as representing a normal operation. The controller moves the blade until the angle of the blade reaches a predetermined target angle when the signal from the operating device is determined as representing the trigger operation while the bulldozer is traveling.
