Abstract

A refuse vehicle includes a chassis including a wheel and an electric motor configured to receive electrical energy and provide power to the wheel to move the refuse vehicle, a body assembly coupled to the chassis and configured to store refuse, a tailgate movably coupled to the body assembly, and an energy storage device coupled to the tailgate and moveable therewith. The electric motor is configured to be powered by the energy storage device.

First claim

What is claimed is:

1 . A refuse vehicle, comprising:
a chassis including a wheel and an electric motor configured to receive electrical energy and provide power to the wheel to move the refuse vehicle; a body assembly coupled to the chassis and configured to store refuse; a tailgate movably coupled to the body assembly; and an energy storage device coupled to the tailgate and moveable therewith, wherein the electric motor is configured to be powered by the energy storage device.

2 . The refuse vehicle of claim 1 , wherein the energy storage device is a battery configured to supply the electrical energy to the electric motor.

3 . The refuse vehicle of claim 1 , wherein the energy storage device is a fuel tank containing a fuel that powers the electric motor.

4 . The refuse vehicle of claim 3 , further comprising a generator including an internal combustion engine, wherein the generator is configured to use the fuel from the fuel tank and supply the electrical energy to the electric motor.

5 . The refuse vehicle of claim 3 , further comprising a fuel cell configured to use the fuel from the fuel tank and supply the electrical energy to the electric motor.

6 . The refuse vehicle of claim 3 , further comprising:
a generator configured to use the fuel from the fuel tank and supply a first portion of the electrical energy to the electric motor; and a battery configured to supply a second portion of the electrical energy to the electric motor.

7 . The refuse vehicle of claim 3 , further comprising a controller and a shutoff valve configured to selectively restrict a flow of fuel from the fuel tank.

8 . The refuse vehicle of claim 7 , further comprising a pressure sensor positioned along the flow of fuel to monitor a pressure thereof.

9 . The refuse vehicle of claim 8 , wherein the controller is configured to control the shutoff valve to restrict the flow of fuel in response the pressure of the flow of fuel falling below a pressure threshold.

10 . The refuse vehicle of claim 7 , further comprising a temperature sensor positioned to monitor a temperature within the refuse vehicle.

11 . The refuse vehicle of claim 10 , wherein the controller is configured to control the shutoff valve to restrict the flow of fuel in response to the temperature within the refuse vehicle exceeding a temperature threshold.

12 . The refuse vehicle of claim 1 , further comprising at least one of a non-structural conduit, a non-structural raceway, and a non-structural channel configured to contain at least one of wiring and a hydraulic line.

13 . The refuse vehicle of claim 1 , further comprising an impact mitigation system comprising at least one frame member positioned to direct impact loads around the energy storage device, wherein the impact mitigation system provides a protected region within which the energy storage device is disposed.

14 . The refuse vehicle of claim 1 , further comprising an active impact mitigation system including at least one sensor positioned to monitor a position of an object within a surrounding environment.

15 . The refuse vehicle of claim 14 , wherein the active impact mitigation system includes a controller coupled to the at least one sensor, the controller configured to engage one or more vehicle systems to at least one of: (a) avoid an impact, (b) mitigate an impact by reducing a relative velocity between the refuse vehicle and the object, (c) isolate or otherwise disengage the energy storage device, and (d) warn an operator of the refuse vehicle of a potential impact in response to data received from the at least one sensor.

16 . The refuse vehicle of claim 15 , wherein the controller is configured to engage the one or more vehicle systems to isolate or otherwise disengage the energy storage device in response to the data received from the at least one sensor.

17 . A refuse vehicle, comprising:
a frame; a wheel coupled to the frame; an electric motor configured to drive a portion of the refuse vehicle relative to the frame in response to receiving electrical energy; a body assembly coupled to the frame; a tailgate coupled to the body assembly and movable between an open position and a closed position; and a battery coupled to the tailgate and moveable therewith, wherein the battery is configured to supply the electrical energy to the electric motor.

18 . The refuse vehicle of claim 17 , wherein the electric motor is configured to drive the wheel relative to the frame to propel the refuse vehicle in response to receiving the electrical energy from the battery.

19 . The refuse vehicle of claim 17 , further comprising an active impact mitigation system including (a) at least one sensor positioned to monitor a position of an object within a surrounding environment and (b) a controller configured to engage one or more vehicle systems to isolate or otherwise disengage the battery in response to data received from the at least one sensor.

20 . A front-loading refuse vehicle, comprising:
a frame; a wheel coupled to the frame; a cab coupled the frame and positioned at a front end of the front-loading refuse vehicle; a body assembly coupled to the frame and extending rearward of the cab, wherein the body assembly is configured to receive a volume of refuse; a tailgate coupled to the body assembly and positioned at a rear end of the front-loading refuse vehicle, wherein the tailgate is movable between an open position and a closed position; an electric motor coupled to the frame and configured to drive the wheel to propel the front-loading refuse vehicle; and a battery coupled to the tailgate and moveable therewith, wherein the battery is configured to power the electric motor, wherein the tailgate includes an impact mitigation system including a frame member positioned to direct impact loads around the battery, wherein the impact mitigation system provides a protected region within which the battery is disposed.
