Abstract

A refuse vehicle has a chassis supporting a plurality of wheels, as well as a motor. A vehicle body is also supported by the chassis and defines a receptacle for storing refuse. A lifting system is coupled to the vehicle body and is movable between a first position and a second position vertically offset from the first position using a hydraulic system. The refuse vehicle also has a processing unit in communication with the lifting system and the motor. The processing unit is configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of the refuse vehicle. The operational modes include at least two different operational modes corresponding to different route types.

First claim

What is claimed is:

1. A refuse vehicle, comprising:
a chassis supporting a plurality of wheels;
a motor supported by the chassis;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein;
a lifting system movable between a first position and a second position vertically offset from the first position using a hydraulic system;
a processing unit in communication with the lifting system and motor and configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of at least one of the motor and the hydraulic system, wherein the preset operational modes include at least two different operational modes corresponding to different route types; and
a human machine interface in communication with the processing unit and including a plurality of inputs, wherein at least two of the plurality of inputs correspond to two different preset operational modes;
wherein upon receiving a selection of one of the plurality of inputs on the human machine interface, the processing unit adjusts the performance parameters of at least one of the motor and the hydraulic system toward values associated with a preset operational mode associated with the at least one of the plurality of inputs selected.

2. The refuse vehicle of claim 1 , wherein the at least two different operational modes corresponding to different route types include at least a residential mode and a commercial mode.

3. The refuse vehicle of claim 2 , wherein when the refuse vehicle is in the residential mode, the processing unit controls a hydraulically-driven compactor within the receptacle to operate at a first frequency and wherein when the refuse vehicle is in the commercial mode, the processing unit controls the compactor to operate at a second frequency lower than the first frequency.

4. The refuse vehicle of claim 1 , wherein the at least two operational modes corresponding to different route types include at least a recycling mode and a garbage mode.

5. The refuse vehicle of claim 4 , wherein when the refuse vehicle is in the recycling mode, the processing unit controls a hydraulically-driven compactor within the receptacle to operate at a first frequency and wherein when the refuse vehicle is in the garbage mode, the processing unit controls the compactor to operate at a second frequency lower than the first frequency.

6. The refuse vehicle of claim 1 , wherein the lifting system is a hydraulic arm assembly.

7. The refuse vehicle of claim 1 , wherein the hydraulic system includes one or more hydraulic pumps, and wherein performance parameters of the one or more hydraulic pumps are adjustable in response to the processing unit receiving a selection of a preset operational mode.

8. The refuse vehicle of claim 1 , wherein adjusting the performance parameters of the hydraulic system includes adjusting an output of at least one hydraulic pump.

9. The refuse vehicle of claim 1 , wherein adjusting the performance parameters of the hydraulic system includes adjusting a performance parameter of a hydraulically-driven compactor positioned within the receptacle.

10. The refuse vehicle of claim 1 , wherein adjusting the performance parameters of the motor includes adjusting a maximum output of the motor.

11. The refuse vehicle of claim 10 , wherein adjusting the performance parameters of the motor includes adjusting a fuel type supplied to the motor.

12. The refuse vehicle of claim 1 , wherein the human machine interface is a graphical user interface presented on a display.

13. The refuse vehicle of claim 12 , wherein the plurality of inputs are presented on the graphical user interface, wherein the display is a touch screen.

14. A refuse vehicle, comprising:
a chassis;
a motor supported by the chassis;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein;
a lifting system movable between a first position and a second position vertically offset from the first position using a hydraulic system;
a processing unit in communication with the lifting system and motor and configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of at least one of the motor and the hydraulic system, wherein the operational modes include at least two different operational modes corresponding to different route types, and wherein the processing unit accesses and executes one of the plurality of preset operational modes in response to receiving a selection corresponding with the route type; and
wherein upon receiving the selection corresponding with the route type, the processing unit adjusts the performance parameters of at least one of the motor and the hydraulic system toward values associated with the preset operational mode associated with the route type.

15. The refuse vehicle of claim 14 , wherein a plurality of inputs corresponding to different route types are positioned about a human machine interface within a cab of the vehicle body, and the selection corresponding with the route type is inputted by a user interacting with one or more of the plurality of inputs.

16. The refuse vehicle of claim 14 , wherein the selection corresponding with the route type is generated by the processing unit in response to receiving a signal from a global positioning system that the refuse vehicle is positioned in a location associated with the route type.

17. The refuse vehicle of claim 14 , wherein the different route types include at least one of the group consisting of: a residential route, a commercial route, a recycling route, and a garbage route.

18. The refuse vehicle of claim 14 , wherein adjusting the performance parameters of the hydraulic system includes adjusting an output of at least one hydraulic pump positioned on the refuse vehicle.

19. A method of controlling a refuse vehicle, comprising:
receiving a selection of a preset operational mode of the refuse vehicle from a plurality of different preset operational modes, the selection of the preset operational mode corresponding with a route type the refuse vehicle is performing;
accessing a memory, with a processing unit in communication with a hydraulic system and a motor of the refuse vehicle, to retrieve preset performance parameters of the refuse vehicle associated with the selected preset operational mode of the refuse vehicle, the performance parameters including at least an output of a hydraulic pump within the hydraulic system; and
adjusting current performance parameters of the refuse vehicle toward the preset performance parameters associated with the selected preset operational mode of the refuse vehicle corresponding with the route type the refuse vehicle is performing.

20. The method of claim 19 , wherein the step of receiving the selection of the preset operational mode is performed by the processing unit upon receiving an indication from a global positioning system that the refuse vehicle is positioned in a location associated with the route type the refuse vehicle is performing.
