Abstract

In one aspect, a method for compressing crop material for ensilage may include monitoring, with a computing device, a location of a work vehicle within a silage heap as the work vehicle traverses a layer of crop material within the silage heap. The method may also include determining, with the computing device, a current density of the layer of crop material as the work vehicle traverses the layer of crop material. Furthermore, the method may include controlling, with the computing device, an operation of the work vehicle based on the monitored location and the determined current density such that the work vehicle compresses the layer of crop material.

First claim

The invention claimed is:

1. A method for compressing crop material for ensilage, the method comprising:
monitoring, with a computing device, a location of a work vehicle within a silage heap as the work vehicle traverses a layer of crop material within the silage heap;
determining, with the computing device, a current density of the layer of crop material as the work vehicle traverses the layer of crop material;
monitoring, with the computing device, a surface roughness of the layer of crop material; and
controlling, with the computing device, an operation of the work vehicle based on the monitored location, the determined current density, and the monitored surface roughness such that the work vehicle compresses the layer of crop material.

2. The method of claim 1 , wherein controlling the operation of the at least one of the work vehicle or the associated implement comprises controlling, with the computing device, the operation of the work vehicle based on the monitored location and the determined current density such that the work vehicle compresses the layer of crop material to a predetermined density.

3. Method of claim 1 , wherein controlling the operation of the at least one of the work vehicle or the associated implement comprises controlling, with the computing device, at least one of a speed of the work vehicle or a direction of travel of the work vehicle.

4. The method of claim 1 , wherein determining the current density of the layer of crop material comprises:
monitoring, with the computing device, a height of a top surface of the layer of crop material; and
determining, with the computing device, the current density of the layer of crop material based on the monitored height.

5. A method for compressing crop material for ensilage, the method comprising:
monitoring, with a computing device, a location of a work vehicle within a silage heap as the work vehicle traverses a layer of crop material within the silage heap;
determining, with the computing device, a current density of the layer of crop material as the work vehicle traverses the layer of crop material, wherein the layer of crop material comprises a top layer of a plurality of layers of crop material within the silage heap, the plurality of layers further comprising a preceding layer positioned directly below the top layer; and
controlling, with the computing device, an operation of the work vehicle based on the monitored location and the determined current density such that the work vehicle compresses the layer of crop material.

6. The method of claim 5 , further comprising:
determining, with the computing device, a height of a top surface of the preceding layer of crop material;
determining, with the computing device, a height of a top surface of the top layer of crop material; and
determining, with the computing device, the current density of the top layer of crop material based on a differential between the determined heights of the top surfaces of the preceding and top layers.

7. The method of claim 5 , further comprising:
receiving, with the computing device, vision-based data associated with a top surface of the top layer of crop material; and
determining, with the computing device, the current density of the top layer of crop material based on the received vision-based data.

8. The method of claim 1 , wherein determining the current density comprises determining, with the computing device, the current density of the layer of crop material based on at least one of a first height of the layer before the work vehicle traverses the layer, a second height of the layer when the work vehicle is traversing the layer, and a third height of the layer after the work vehicle has traversed the layer.

9. A system for compressing crop material for ensilage, the system comprising:
a work vehicle;
a sensor configured to capture data indicative of a current density of a layer of crop material within a silage heap, wherein the sensor comprises a location sensor configured to capture data indicative of a height of a top surface of the layer of crop material, the location sensor communicatively coupled to the controller; and
