Abstract

Operating a refuse collection vehicle to collect refuse from a refuse container includes positioning a refuse collection vehicle with respect to a refuse container to be emptied, and manually engaging a switch to initiate a dump cycle to be performed by the refuse collection vehicle on the refuse container. The dump cycle includes engaging the refuse container with a portion of the vehicle, lifting the engaged refuse container to a dump position, and moving the refuse container to release contents of the refuse container into a hopper of the refuse collection vehicle. The dump cycle continues to completion as long as the switch remains manually engaged.

First claim

What is claimed is:

1. A computer-implemented method of operating a refuse collection vehicle to eject refuse from a body of the refuse collection vehicle, the method performed by at least one computer device, the method comprising:
responsive to a detected engaging of a switch, initiating an ejection cycle to be performed by the refuse collection vehicle on the refuse in the body;
responsive to a detected disengaging of the switch, causing the refuse collection vehicle to automatically stop the ejection cycle;
determining a point at which the ejection cycle was stopped based at least partly on data collected by one or more sensors on the refuse collection vehicle; and
responsive to a detected reengaging of the switch subsequent to the detected disengaging, causing the refuse collection vehicle to continue the ejection cycle from the point at which the ejection cycle was stopped, wherein the ejection cycle continues to completion as long as the switch remains reengaged.

2. The method of claim 1 , wherein the ejection cycle comprises:
moving an ejection cylinder of the refuse collection vehicle to eject at least a portion of the refuse.

3. The method of claim 2 , wherein ejecting the at least a portion of the refuse comprises moving a packer coupled to the ejection cylinder to eject the at least a portion of the refuse from the body of the refuse collection vehicle.

4. The method of claim 2 , wherein moving the ejection cylinder of the refuse collection vehicle to eject the at least a portion of the refuse comprises extending and retracting the ejection cylinder one or more times to eject the at least a portion of the refuse from the body of the refuse collection vehicle.

5. The method of claim 4 , wherein the ejection cylinder extends to a full eject position and retracts to a second position, the second position being a predetermined distance from the full eject position.

6. The method of claim 5 , further comprising receiving, from an operator of the refuse collection vehicle, the predetermined distance for the second position.

7. The method of claim 2 , further comprising responsive to a detected engaging of a second switch, causing the ejection cylinder to move to a start position.

8. The method of claim 1 , wherein the ejection cycle comprises unlocking a tailgate of the refuse collection vehicle.

9. The method of claim 1 , wherein the ejection cycle comprises lifting a tailgate of the refuse collection vehicle.

10. The method of claim 1 , wherein the ejection cycle comprises lowering a tailgate of the refuse collection vehicle to a closed position.

11. The method of claim 1 , wherein the ejection cycle comprises locking a tailgate of the refuse collection vehicle.

12. The method of claim 1 , wherein the data collected by the one or more sensors on comprises a location of an ejection cylinder of the refuse collection vehicle when the switch was disengaged.

13. The method of claim 1 , wherein the data collected by the one or more sensors comprises a pressure within the body when the switch was disengaged.

14. The method of claim 1 , wherein initiating the ejection cycle to be performed by the refuse collection vehicle on the refuse in the body comprises determining that a tailgate of the refuse collection vehicle is not lowered.

15. The method of claim 1 , wherein initiating the ejection cycle to be performed by the refuse collection vehicle on the refuse in the body comprises determining that a pressure within the body of the refuse collection vehicle exceeds a threshold pressure.

16. The method of claim 1 , further comprising, in response to detecting completion of the ejection cycle, causing a light inside the refuse collection vehicle to illuminate to indicate that the ejection cycle is complete.

17. A system comprising:
at least one processor; and
memory communicably coupled to the at least one processor, the memory storing instructions which, when executed, cause the at least one processor to perform operations comprising:
responsive to a detected engaging of a switch, initiating an ejection cycle to be performed by a refuse collection vehicle on refuse in a body of the refuse collection vehicle;
responsive to a detected disengaging of the switch, causing the refuse collection vehicle to automatically stop the ejection cycle;
determining a point at which the ejection cycle was stopped, based at least partly on data collected by one or more sensors on the refuse collection vehicle; and
responsive to a detected reengaging of the switch subsequent to the detected disengaging, causing the refuse collection vehicle to continue the ejection cycle from the point at which the ejection cycle was stopped, wherein the ejection cycle continues to completion as long as the switch remains reengaged.

18. The system of claim 17 , wherein the data collected by the one or more sensors on comprises one or more of (i) a location of an ejection cylinder of the refuse collection vehicle when the switch was disengaged, or (ii) a pressure within the body when the switch was disengaged.

19. The system of claim 17 , wherein initiating the ejection cycle to be performed by the refuse collection vehicle on the refuse in the body comprises one or more of (i) determining that a tailgate of the refuse collection vehicle is not lowered, or (ii) determining that a pressure within the body of the refuse collection vehicle exceeds a threshold pressure.

20. The system of claim 17 , wherein the at least one processor is disposed on board the refuse collection vehicle.
