Abstract
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.

A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- determine a target design topography at least partially positioned below an actual topography, the target design topography being indicative of a target trajectory of the work implement,
- acquire an end position and a target distance of work performed by the work vehicle,
- determine, as a start position, a position that is away from the end position by the target distance,
- generate a command signal
- to start the work from the start position toward the end position and
- to operate the work implement according to the target design topography, and
- modify the target distance based on a result of the work.
A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- determine a target design topography at least partially positioned below an actual topography, the target design topography being indicative of a target trajectory of the work implement,
- acquire an end position and a target soil amount of work performed by the work vehicle,
- determine, as a start position, a position that is away from the end position by the target soil amount,
- generate a command signal
- to start the work from the start position toward the end position and
- to operate the work implement according to the target design topography, and
- modify the target soil amount based on a result of the work.
A control system for a work vehicle including a travel device and a work implement, the control system comprising:
- a controller configured to
- determine a target design topography least partially positioned below an actual topography, the target design topography being indicative of a target trajectory of the work implement,
- acquire an end position and a target distance of work performed by the work vehicle,
- determine, as a start position, a position that is away from the end position by the target distance,
- generate a command signal
- to start the work from the start position toward the end position and
- to operate the work implement according to the target design topography,
- acquire a load parameter indicating a magnitude of a load on the travel device, and
- modify the target distance according to the load parameter.
