Abstract

A control system for a work vehicle includes a controller configured to establish a first bounding shape within a storage compartment. The controller is also configured to establish a second bounding shape by mirroring the first bounding shape along a lateral centerline of the work vehicle. In addition, the controller is configured to automatically engage product flow from a conveyor outlet to the storage compartment in response to the storage compartment being positioned on a first lateral side of the work vehicle and the conveyor outlet being positioned within the first bounding shape, and to automatically engage product flow from the conveyor outlet to the storage compartment in response to the storage compartment being positioned on a second lateral side of the work vehicle and the conveyor outlet being positioned within the second bounding shape.

First claim

The invention claimed is:

1. A control system for a work vehicle comprising a controller and a user interface, wherein the controller has a memory and a processor;
wherein the controller is configured to:
establish a first bounding shape within a storage compartment, wherein the first bounding shape is completely surrounded by an inlet of the storage compartment while the storage compartment is positioned on a first lateral side of the work vehicle;
automatically establish a second bounding shape based on the first bounding shape by mirroring the first bounding shape along a lateral centerline of the work vehicle, such that the second bounding shape is completely surrounded by the inlet of the storage compartment while the storage compartment is positioned on a second lateral side of the work vehicle, opposite the first lateral side;
automatically engage product flow from a conveyor outlet to the storage compartment in response to the storage compartment being positioned on the first lateral side of the work vehicle and the conveyor outlet being positioned within the first bounding shape, and automatically engage product flow from the conveyor outlet to the storage compartment in response to the storage compartment being positioned on the second lateral side of the work vehicle and the conveyor outlet being positioned within the second bounding shape;
instruct an actuator to move the conveyor outlet to the first lateral side of the work vehicle in response to the storage compartment being positioned on the first lateral side of the work vehicle; and
instruct the actuator to move the conveyor outlet to the second lateral side of the work vehicle in response to the storage compartment being positioned on the second lateral side of the storage compartment; and

wherein the user interface is configured to receive input indicative of the first bounding shape, and the controller is configured to establish the first bounding shape based on the input.

2. The control system of claim 1 , wherein the first bounding shape is a bounding rectangle.

3. The control system of claim 2 , wherein the controller is configured to establish a plurality of zones within the bounding rectangle, wherein the plurality of zones do not overlap one another.

4. The control system of claim 1 , wherein the input comprises a size of the first bounding shape, dimensions of the first bounding shape, a position of the first bounding shape relative to the storage compartment, positions of points along a periphery of the first bounding shape, a length of a linkage between the storage compartment and a haul vehicle coupled to the storage compartment, or a combination thereof.
