Abstract
At least a portion of a first target design topography is positioned below an actual topography. At least a portion of a second target design topography is positioned below the actual topography and is inclined with respect to the first target design topography. A controller generates a command signal to operate a work implement according to the first target design topography in an area where the first target design topography is positioned above the second target design topography. The controller generates a command signal to operate the work implement according to the second target design topography in an area where the second target design topography is positioned above the first target design topography.

A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- determine a first target design topography at least partially positioned below an actual topography, the first target design topography being indicative of a target trajectory of the work implement,
- determine a second target design topography at least partially positioned below an actual topography, the second target design topography being inclined with respect to the first target design topography, and the second target design topography being indicative of a target trajectory of the work implement, and
- generate a command signal
- to operate the work implement according to the first target design topography in an area where the first target design topography is positioned above the second target design topography and
- to operate the work implement according to the second target design topography in an area where the second target design topography is positioned above the first target design topography.
A method executed by a controller for controlling a work vehicle including a work implement, the method comprising:
- determining a first target design topography at least partially positioned below an actual topography, the first target design topography being indicative of a target trajectory of the work implement;
- determining a second target design topography at least partially positioned below an actual topography, the second target design topography being inclined with respect to the first target design topography, and the second target design topography being indicative of a target trajectory of the work implement;
- and
- generating a command signal
- to operate the work implement according to the first target design topography in an area where the first target design topography is positioned above the second target design topography and
- to operate the work implement according to the second target design topography in an area where the second target design topography is positioned above the first target design topography.
A control system for a work vehicle including a work implement, the control system comprising:
- a controller configured to
- determine a first target design topography at least partially positioned below an actual topography, the first target design topography being indicative of a target trajectory of the work implement,
- determine an exit path at least partially positioned below the actual topography, the exit path being inclined with respect to the first target design topography, and the exit path being indicative of a target trajectory of the work implement, and
- generate a command signal
- to operate the work implement along the exit path in a region positioned below the actual topography and
- to operate the work implement along the exit path in a region positioned above the actual topography.
