Abstract
In accordance with an example embodiment, a method of operating a work vehicle with an ejector body may include receiving a position signal indicative of a position of the work vehicle, receiving a target profile indicative of a target topography for an area, receiving an ejection command at a controller and entering the controller into an ejection mode based on the ejection command, and controlling, with the controller, in the ejection mode, at least one of a speed of the work vehicle and a speed of an ejector included in the ejector body based on the position signal and the target profile, to spread a load of material from the ejector body onto a ground surface.
Claims20
A device for controlling an ejector of a work vehicle with an ejector body, the device comprising:
- a controller configured to:
- receive a target profile, the target profile indicative of a target topography for an area of land, the target profile different from a current topography for the area of land, the target topography and the current topography each describing a three-dimensional surface for the area of land;
- receive a position signal indicative of a position of the work vehicle on the area of land;
- enter an ejection mode upon receipt of an ejection command;
- and
- control, while in the ejection mode, based on both the position signal and the target profile, at least one of a speed of the ejector and a speed of the work vehicle, in order to eject material from the ejector body onto the area of land so as to raise the current topography toward the target profile.

- receive a position signal indicative of a position of the work vehicle on the area of land;
- determine, based on the target profile and the position signal, a distance from the current topography at the position of the work vehicle to the target profile at the position of the work vehicle;
- enter an ejection mode upon receipt of an ejection command;
- and
- control, while in the ejection mode, based on the distance, at least one of a speed of the ejector and a speed of the work vehicle, in order to eject material from the ejector body onto the area of land so as to raise the current topography toward the target profile.
