Abstract

A receiving vehicle is automatically identified and the number of times it is filled is automatically counted. Control signals can be generated based on the number of times the receiving vehicle is filled.

First claim

What is claimed is:

1. A material loading system, comprising:
a receiving vehicle identification system that automatically identifies a receiving vehicle that receives material from a material loading vehicle;
a fill level detection system that automatically detects a fill level of the material in the identified receiving vehicle;
a fill data generation system that automatically generates a load count corresponding to the identified receiving vehicle, the load count being indicative of a number of times that the identified receiving vehicle has been filled with material during a load count window; and
an output generator that generates an output control signal to output the load count corresponding to the identified receiving vehicle.

2. The material loading system of claim 1 and further comprising:
a weight generation system configured to automatically generate an estimated weight value indicative of an estimated weight of the material in the identified receiving vehicle based on the identified receiving vehicle and the detected fill level.

3. The material loading system of claim 2 and further comprising:
a model accessing system that identifies a receiving vehicle weight estimation model corresponding to the identified receiving vehicle, and wherein the weight generation system is configured to use the receiving vehicle weight estimation model corresponding to the identified receiving vehicle to generate the estimated weight value corresponding to the material in the identified receiving vehicle.

4. The material loading system of claim 3 wherein the identified receiving vehicle is of a receiving vehicle type and wherein the receiving vehicle weight estimation model comprises:
a vehicle-specific weight estimation model specific to the identified receiving vehicle or the receiving vehicle type.

5. The material loading system of claim 3 wherein the receiving vehicle weight estimation model comprises a function or classifier that correlates the fill level for the identified receiving vehicle to the estimated weight value.

6. The material loading system of claim 2 wherein the fill data generation system comprises:
a load weight generator configured to generate fill data corresponding to the identified receiving vehicle that includes the estimated weight value.

7. The material loading system of claim 4 and further comprising:
a model training system configured to receive, as model training inputs, an identity of the receiving vehicle, the fill level for the receiving vehicle, and a measurement indicative of a measured weight of the material in the receiving vehicle and to train the vehicle-specific weight estimation model based on the model training inputs.

8. The material loading system of claim 2 and further comprising:
a weight limit comparison system configured to obtain a weight limit corresponding to the identified receiving vehicle and automatically perform a comparison to compare the estimated weight value corresponding to the identified receiving vehicle, as the identified receiving vehicle is being loaded with material, to the weight limit corresponding to the identified receiving vehicle and generate a comparison output based on the comparison; and
a control signal generator configured to generate a control signal based on the comparison output.

9. The material loading system of claim 8 wherein the control signal generator is configured to generate a control signal to control an operator interface mechanism to surface an output to an operator indicative of a current estimated weight of material in the receiving vehicle relative to a weight limit for the identified receiving vehicle based on the comparison signal.

10. The material loading system of claim 1 and further comprising:
an image capture device configured to capture an image of a portion of the receiving vehicle and wherein the receiving vehicle identification system comprises an image processing system configured to identify a vehicle-identifying attribute in the image of the receiving vehicle and to identify the receiving vehicle based on the vehicle-identifying attribute.

11. The material loading system of claim 1 wherein
the material loading vehicle comprises an agricultural harvester, and
the load count window comprises at least one of:
a length of harvesting operation,
a predefined time period,
shift, or
a field.

12. A computer implemented method of controlling a material loading system, the computer implemented method comprising:
automatically identifying a receiving vehicle that receives material from a material loading vehicle;
automatically detecting a fill level of the material in the identified receiving vehicle;
automatically generating a load count corresponding to the identified receiving vehicle, the load count being indicative of a number of times that the identified receiving vehicle has been filled with material during a load count window; and
generating an output control signal to output the load count corresponding to the identified receiving vehicle.

13. The computer implemented method of claim 12 and further comprising:
automatically generating an estimated weight value indicative of an estimated weight of the material in the identified receiving vehicle based on the identified receiving vehicle and the detected fill level.

14. The computer implemented method of claim 13 wherein automatically generating an estimated weight value comprises:
identifying a receiving vehicle weight estimation model corresponding to the identified receiving vehicle; and
using the receiving vehicle weight estimation model corresponding to the identified receiving vehicle to generate the estimated weight value corresponding to the material in the identified receiving vehicle.

15. The computer implemented method of claim 13 and further comprising:
generating fill data corresponding to the identified receiving vehicle that includes the estimated weight value.

16. The computer implemented method of claim 14 and further comprising:
training the receiving vehicle weight estimation model based on a set of model training inputs comprising an identity of the receiving vehicle, the fill level for the receiving vehicle, and a measurement indicative of a measured weight of the material in the receiving vehicle.

17. The computer implemented method of claim 13 and further comprising:
obtaining a weight limit corresponding to the identified receiving vehicle;
automatically performing a comparison to compare the estimated weight value corresponding to the identified receiving vehicle, as the identified receiving vehicle is being loaded with material, to the weight limit corresponding to the identified receiving vehicle;
generating a comparison output based on the comparison; and
generating a control signal based on the comparison output.

18. The computer implemented method of claim 17 wherein generating a control signal comprises:
generating the control signal to control an operator interface mechanism to surface an output to an operator indicative of a current estimated weight of material in the receiving vehicle relative to a weight limit for the identified receiving vehicle based on the comparison signal.

19. The computer implemented method of claim 12 automatically identifying a receiving vehicle comprises:
capturing an image of a portion of the receiving vehicle;
performing image processing on the captured image to identify a vehicle-identifying attribute in the image of the receiving vehicle; and
identifying
