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.
Claims14
A method of operating a work vehicle with an ejector body, the method comprising the steps of:
- receiving a position signal indicative of a position of the work vehicle;
- receiving a target profile indicative of a target topography for an area, the target topography indicative of a three-dimensional surface for an area of land;
- 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 in the area;
- wherein:
- the speed of the work vehicle is controlled based on the speed of the ejector and a comparison of the target profile and the position signal;
- or
- the speed of the ejector is controlled based on the speed of the work vehicle and the comparison of the target profile and the position signal.
A work vehicle with an ejector body comprising:
- an engine;
- a transmission;
- a GNSS receiver configured to provide a position signal indicative of a position of the work vehicle;
- a vehicle speed sensor configured to provide a speed signal;
- an ejector connected to the ejector body and movable by an actuator at an ejector speed between a retracted position and an extended position;
- and
- a controller in communication with the GNSS receiver, the controller configured to:
- receive the position signal;
- receive a target profile indicative of a target topography for an area, the target topography indicative of a three-dimensional surface for an area of land;
- receive an ejection command;
- enter an ejection mode after receiving the ejection command;
- and
- control, in the ejection mode, at least one of a speed of the engine, a gear selection of the transmission, and the ejector speed based on the target profile and the position signal;
- wherein the controller is further configured to:
- control the speed of the engine based on a comparison of the target profile and the position signal;
- or
- control the ejector speed based on the speed signal and the comparison of the target profile and the position signal.
