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 vehicle body supported by the chassis and defining a receptacle for storing refuse therein;
a lifting system configured to engage and lift refuse containers to transfer refuse within the refuse containers into the receptacle, wherein the lifting system is operated with a hydraulic system;
a processing unit in communication with the lifting system and configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of the lifting 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 the two different preset operational modes, the at least two different operational modes corresponding to at least one of (i) different route types including at least a residential mode and a commercial mode, or (ii) different route types including at least a recycling mode and a garbage mode;
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 the lifting system toward values associated with a preset operational mode that is associated with the at least one of the plurality of inputs selected.

2. The refuse vehicle of claim 1 , wherein when the refuse vehicle is in the residential mode, the processing unit controls the lifting system to operate at a first grip force, and wherein when the refuse vehicle is in the commercial mode, the processing unit controls the lifting system to operate at a second grip force greater than the first grip force.

3. The refuse vehicle of claim 1 , wherein when the refuse vehicle is in the recycling mode, the processing unit controls the lifting system to operate at a first grip force, and wherein when the refuse vehicle is in the garbage mode, the processing unit controls the lifting system to operate at a second grip force different than the first grip force.

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

5. The refuse vehicle of claim 4 , wherein the performance parameters of the lifting system adjusted based upon the selection of the preset operational mode include at least a positioning of a set of jaws within the hydraulic arm assembly and a clamping force of the set of jaws within the hydraulic arm assembly.

6. The refuse vehicle of claim 4 , further comprising a carry can assembly supported by one of the chassis or the vehicle body, and wherein at least a portion of the hydraulic arm assembly is incorporated into a carry can assembly.

7. The refuse vehicle of claim 1 , wherein the lifting system is a set of forks, and wherein a positioning of the forks is adjustable based upon the selection of the preset operational mode.

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

9. The refuse vehicle of claim 8 , wherein the plurality of inputs are presented on the graphical user interface, wherein the display is a touch screen.

10. A refuse vehicle, comprising:
a chassis supporting a plurality of wheels;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein;
a lifting system configured to engage and lift refuse containers to transfer refuse within the refuse containers into the receptacle;
a processing unit in communication with the lifting system and configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of the lifting system, wherein the operational modes include at least two different operational modes corresponding to different route types including at least one of a residential route, a commercial route, an industrial route, a recycling route, or a garbage route, and wherein in response to receiving a selection corresponding with the route type the processing unit is configured to access one of the plurality of preset operational modes and to adjust the performance parameters of the lifting system toward values associated with the preset operational mode associated with the route type.

11. The refuse vehicle of claim 10 , wherein a plurality of inputs corresponding to different route types are accessible from a human machine interface within a cab of the vehicle body, and the selection corresponding with the route type is input by a user interacting with at least one of the plurality of inputs.

12. The refuse vehicle of claim 10 , 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 indicating that the refuse vehicle is positioned in a location that is associated with the route type.

13. The refuse vehicle of claim 10 , wherein the selection corresponding with the route type is generated by the processing unit in response to receiving a signal from a sensor on the refuse vehicle, wherein the sensor is configured to detect characteristics of a refuse container.

14. The refuse vehicle of claim 13 , wherein the characteristics of a refuse container detected by the sensor include one of a size or a color of the refuse container.

15. The refuse vehicle of claim 10 , wherein the performance parameters of the lifting system adjustable by the processing unit include at least a clamping force and a jaw positioning for a hydraulic arm assembly.

16. A refuse vehicle, comprising:
a chassis;
a vehicle body supported by the chassis and defining a receptacle for storing refuse therein;
a hydraulically-driven lifting system configured to engage and lift a waste container to transfer refuse within the waste container into the receptacle; and
a processing unit in communication with the hydraulically-driven lifting system and configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance of the hydraulically-driven lift system based upon a selection corresponding to a refuse type, the preset operational modes including a residential route and an industrial route, the preset operational mode for the residential route including a first gripping force of jaws of the hydraulically-driven lifting system that differs from a second gripping force of jaws of the hydraulically-driven lifting system that is associated with the preset operational mode for the industrial route.
