Abstract
A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller acquires work range data indicative of a work range. The controller determines a division distance by dividing an entire length of the work range by a predetermined number of divisions. The controller determines a plurality of starting positions so that the distance between each starting position matches the division distance in the work range. The controller generates an instruction signal to actuate the work implement from the plurality of starting positions.
Claims12
A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- acquire work range data indicative of a work range;
- determine a division distance by dividing an entire length of the work range by a predetermined number of divisions;
- determine a plurality of starting positions so that a distance between each starting position matches the division distance in the work range, the plurality of starting positions including a first starting position and a second starting position disposed farther rearward with respect to a vehicle traveling direction than the first starting position;
- and
- generate an instruction signal to actuate the work implement successively from each of the plurality of starting positions in the traveling direction such that the work implement is actuated from the first starting position and, after completing work from the first starting position, the work vehicle is moved to the second starting position and the work implement is actuated from the second starting position.
A method executed by a controller for controlling a work vehicle including a work implement, the method comprising:
- acquiring work range data indicative of a work range;
- determining a division distance by dividing an entire length of the work range by a predetermined number of divisions;
- determining a plurality of starting positions so that a distance between each starting position matches the division distance in the work range, the plurality of starting positions including a first starting position and a second starting position disposed farther rearward with respect to a vehicle traveling direction than the first starting position;
- and
- generating an instruction signal to actuate the work implement successively from each of the plurality of starting positions in the traveling direction such that the work implement is actuated from the first starting position and, after completing work from the first starting position, the work vehicle is moved to the second starting position and the work implement is actuated from the second starting position.
A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- acquire work range data indicative of a work range;
- determine a target design topography indicative of a target locus of the work implement, at least a portion of the target design topography being positioned below an actual topography in the work range,
- determine a divided soil amount by dividing a total soil amount by a predetermined number of divisions, the total soil amount being between the target design topography and the actual topography within the work range,
- determine a plurality of starting positions so that soil amounts between each of the starting positions and between the target design topography and the actual topography match the divided soil amount in the work range, and
- generate an instruction signal to actuate the work implement from the plurality of starting positions.
