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 configured to engage and lift waste containers to transfer refuse within waste containers into the receptacle 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 hydraulic system. The operational modes include at least two different operational modes corresponding to different refuse 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 moveable between a first position and a second position that is offset from the first position;
a processing unit 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 lifting system or the motor, wherein the performance parameters modify the operation of the at least one of the motor or the lifting system; and
a human machine interface in communication with the processing unit and including a plurality of inputs, each of the plurality of inputs corresponding to at least one of the plurality of 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 associated with the at least one of the plurality of preset operational modes corresponding with the at least one of the plurality of inputs selected.

2. The refuse vehicle of claim 1 , wherein the plurality of preset operational modes include a first power type mode and a second power type mode, the second power type mode being different than the first power type mode.

3. The refuse vehicle of claim 2 , wherein the first power type mode comprises a first fuel mode corresponding with a first fuel and the second power type mode comprises a second fuel mode correspond with a second fuel, the second fuel being different than the first fuel.

4. The refuse vehicle of claim 3 , wherein the first fuel is diesel and the second fuel is compressed natural gas (CNG).

5. The refuse vehicle of claim 4 , wherein when the refuse vehicle is in the second fuel mode, the processing unit controls a fuel system within the vehicle to transition to use a fuel mixture at least partly including CNG.

6. The refuse vehicle of claim 4 , wherein when the refuse vehicle is in the second fuel mode the processing unit controls at least one vehicle subsystem to operate below a rated capacity.

7. The refuse vehicle of claim 2 , wherein the first power type mode is an electric mode and wherein the second power type mode is a fuel mode.

8. The refuse vehicle of claim 7 , wherein the fuel mode uses at least one of diesel or compressed natural gas (CNG).

9. The refuse vehicle of claim 1 , wherein the plurality of preset operational modes include at least two different operational modes corresponding to different ambient temperature ranges.

10. The refuse vehicle of claim 1 , wherein the processing unit automatically selects one of the plurality of preset operational modes based on a sensed condition.

11. A method of controlling a refuse vehicle, comprising;
receiving a selection of a preset operational mode of the refuse vehicle from a plurality of preset operational modes;
accessing a memory, with a processing unit in communication with a lifting 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 preset performance parameters including a heater control; and
adjusting current performance parameters of the refuse vehicle to equal the preset performance parameters associated with the selected preset operational mode of the refuse vehicle,
wherein the memory stores a plurality of selectable preset operational modes for the refuse vehicle, the plurality of preset operational modes including at least a standard mode and a cold mode, the cold mode being different than the standard mode.

12. The method of claim 11 , wherein the selection of the preset operational mode of the refuse vehicle is received by the processing unit after performing the steps of:
detecting, with a temperature sensor, an ambient temperature of the refuse vehicle;
comparing, with the processing unit, the ambient temperature to a threshold temperature stored within the memory; and
accessing the memory, with the processing unit, to retrieve the preset operational mode of the refuse vehicle associated with the ambient temperature upon determining that the ambient temperature of the refuse vehicle corresponds to at least one preset operational mode.

13. The method of claim 11 , wherein in the cold mode the processing unit performs the steps of:
dead-heading the lifting system to generate heat.

14. The method of claim 11 , wherein the selection of the preset operational mode of the refuse vehicle is received by the processing unit after performing the steps of:
detecting, with a temperature sensor, a temperature of the lifting system;
comparing, with the processing unit, the temperature of the lifting system to a threshold temperature stored within the memory; and
accessing the memory, with the processing unit, to retrieve the preset operational mode of the refuse vehicle associated with the temperature of the lifting system upon determining that the temperature of the lifting system corresponds to at least one preset operational mode.

15. 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 moveable between a first position and a second position that is offset from the first position;
a processing unit 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 lifting system or the motor, wherein the plurality of preset operational modes includes at least two different operational modes corresponding to different ambient temperature ranges; and
a human machine interface in communication with the processing unit and including a plurality of inputs, at least one input of the plurality of inputs corresponding to each of the at least two different 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 or the lifting system toward values associated with the preset operational mode corresponding with the at least one of the plurality of inputs selected.

16. The refuse vehicle of claim 15 , wherein the plurality of preset operational modes comprises a standard mode and a cold mode, the cold mode different than the standard mode.

17. The refuse vehicle of claim 16 , wherein when the refuse vehicle is in the cold mode, at least one system of the refuse vehicle is dead-headed to generate heat.

18. The refuse vehicle of claim 16 , wherein the processing unit automatically selects the cold mode when an ambient temperature is a below a threshold value.

19. The refuse vehicle of claim 18 , wherein the ambient temperature is detected by a sensor positioned on the refuse vehicle, and wherein the sensor is in communication with the processing unit.

20. The refuse vehicle of claim 15 , wherein the motor is an electric motor supplied by a battery.
