A grading machine may include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined ditching positions based on the input.

This description provides an autonomous or semi-autonomous earth shaping vehicle that is capable of cooperatively filling earth into a fill location in a dig site. A first earth shaping vehicle configured with a hauling tool carrying a volume of earth navigates to the fill location. At the fill location, the first earth shaping vehicle navigates over a target tool path to fill earth from the hauling tool into the fill location. As the first earth shaping vehicle fills earth into the fill location, a measurement sensor coupled to the first earth shaping vehicle measures a compaction level of earth filled into the fill location. If the measured compaction level is determined to be below a threshold compaction level, the first earth shaping vehicle communicates a request for a second earth shaping vehicle configured with a compaction tool to compact earth in the fill location.

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 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.

A controller acquires a size of a recess included in an actual topography within a work range. The controller determines whether the size of the recess is larger than a predetermined recess threshold. When the size of the recess is larger than the predetermined recess threshold, the controller determines a first area and a second area divided at a position of the recess in the work range. The controller determines a first target design topography indicative of a target trajectory of a work implement for the first area. The controller generates a command signal to operate the work implement according to the first target design topography.

A work vehicle includes an engine, a drive wheel, a power transmission mechanism configured to transmit a driving power of the engine to the drive wheel, and a control unit configured to control the power transmission mechanism. The power transmission mechanism has a torque converter including a first clutch, and a second clutch coupled to the torque converter. The control unit controls an oil pressure supplied to the first clutch to a predetermined oil pressure when the second clutch is partially engaged.

A vehicle may be configured to recognize a material pile and locate the material pile within a physical environment. The vehicle may also determine various characteristics or properties associated with the material pile and, based on the determined characteristics, define one or more tasks associated with spreading the material over a defined region according to defined spreading parameters.

A controller may determine, using a first sensor device of the machine, an articulation angle of the machine. The controller may adjust, based on the articulation angle, a size of an object detection area to obtain an adjusted object detection area. The object detection area may be associated with an articulation joint of the machine.

A system controls a work machine at a work site. The system includes a machine position sensor that detects a position of the work machine, a shovel position sensor that detects a position of a shovel, and a controller that acquires machine position data indicative of the position of the work machine and shovel position data indicative of the position of the shovel. The controller determines a work area that includes a plurality of work lanes extending in a predetermined work direction at the work site. The controller allocates the work machine to the plurality of work lanes. The controller determines, as a work restricted area of the work machine, a predetermined range in which the position of the shovel is used as a reference at the work site. The controller controls the work machine so that automatic operation of the work machine in the work restricted area is restricted.

A system includes an input device, a display, and a processor that receives a signal indicative of operation of the input device and outputs a signal to display an image on the display. The processor acquires current terrain data and displays a site image indicative of at least a part of a work site on the display based on the current terrain data. The processor acquires area data including a position and size of a work area designated by the input device on the site image. The processor acquires work data indicative of a work direction in the work area. The processor determines an arrangement of a plurality of work lanes extending in the work direction in the work area based on the area data and the work data. The processor sends an automatic operation command to the work machine according to the arrangement of the work lanes.
