Ejector control for spreading material according to a profile
First Claim
1. 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;
orthe 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.

11. 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;
orcontrol the ejector speed based on the speed signal and the comparison of the target profile and the position signal. - View Dependent Claims (12, 13, 14)
