Abstract

A refuse vehicle includes a chassis, a body, a lock, a tailgate, an ejector, an actuator, a second actuator, and a processor. The body defines a receptacle for storing refuse. The lock is coupled to the body and is configured to releasably secure a movable tailgate. The receptacle contains the ejector. The ejector can transition from a first position that is spaced from the tailgate to a second position proximate the tailgate. The actuator is configured to transition the ejector from the first position to the second position. The second actuator is configured to move the tailgate. The processor is configured to selectively unlock the tailgate and transition the ejector from the first position to the second position in response to receiving a single input to thereby eject refuse from the receptacle without receiving multiple inputs.

First claim

What is claimed is:

1. A refuse vehicle, comprising:
a chassis;
a body supported by the chassis and defining a receptacle configured to store refuse therein, the receptacle having a first end and an opposing second end;
a lock coupled to the body, wherein the lock is selectively repositionable between a locked position and an unlocked position;
a tailgate positioned at the second end of the receptacle, wherein the tailgate is pivotally coupled to the body and selectively repositionable between an open position and a closed position, wherein the tailgate is configured to be releasably secured in the closed position by the lock;
an ejector positioned within the receptacle, wherein the ejector is slidable within the receptacle between a first position that is spaced from the tailgate and a second position proximate the tailgate, wherein the ejector is a compactor, and wherein the ejector is at least partially defined by a packer extending obliquely to a floor of the receptacle;
an actuator coupled to the body and the ejector, the actuator configured to transition the ejector between the first position and the second position;
a second actuator coupled to the tailgate and the body and configured to transition the tailgate from the closed position to the open position; and
a processor configured to:
provide command signals to (a) selectively reconfigure the lock into the unlocked position to unlock the tailgate and (b) transition the ejector from the first position to the second position both in response to receiving a single input to thereby eject refuse from the receptacle without receiving multiple input commands; and
provide command signals to the second actuator to transition the tailgate from the closed position to the open position in response to receiving the single input.

2. The refuse vehicle of claim 1 , further comprising a lifting system proximate the body and movable relative to the receptacle.

3. The refuse vehicle of claim 1 , wherein the processor is configured to receive the single input from a remote device.

4. The refuse vehicle of claim 1 , wherein the processor is configured provide command signals to the actuator to fully extend the actuator only when the processor receives an indication from a first sensor that the lock is in the unlocked position and a second indication from a second sensor that the tailgate is in the open position.

5. The refuse vehicle of claim 1 , further comprising a sensor, wherein the sensor is configured to detect an obstacle, and wherein the processor compares a value of the sensor to a predetermined value.

6. The refuse vehicle of claim 5 , wherein the processor is configured to provide command signals to drive the refuse vehicle forward when the ejector is transitioning from the first position to the second position in response to the single input.

7. The refuse vehicle of claim 1 , wherein the processor automatically receives the single input upon the refuse vehicle entering a geographically indicated location.

8. A refuse vehicle, comprising:
a chassis;
a body supported by the chassis and defining a receptacle configured to store refuse therein, the receptacle having a first end and an opposing second end;
a lock coupled to the body, wherein the lock is selectively repositionable between a locked position and an unlocked position;
a tailgate positioned at the second end of the receptacle, wherein the tailgate is pivotally coupled to the body and selectively repositionable between an open position and a closed position, wherein the tailgate is configured to be releasably secured in the closed position by the lock;
an ejector positioned within the receptacle, wherein the ejector is slidable within the receptacle between a first position that is spaced from the tailgate and a second position proximate the tailgate;
an actuator coupled to the body and the ejector, the actuator configured to transition the ejector between the first position and the second position;
a second actuator coupled to the tailgate and the body and configured to transition the tailgate from the closed position to the open position;
a processor configured to:
provide command signals to (a) selectively reconfigure the lock into the unlocked position to unlock the tailgate and (b) transition the ejector from the first position to the second position both in response to an indication of the refuse vehicle entering a geographically indicated location to thereby eject refuse from the receptacle without receiving multiple input commands; and
provide command signals to the second actuator to transition the tailgate from the closed position to the open position in response to the indication of the refuse vehicle entering the geographically indicated location.

9. The refuse vehicle of claim 8 , further comprising a lifting system proximate the body and movable relative to the receptacle.

10. The refuse vehicle of claim 8 , further comprising a sensor, wherein the sensor is configured to detect an obstacle, and wherein the processor compares a value of the sensor to a predetermined value.

11. The refuse vehicle of claim 10 , wherein the processor is configured to provide command signals to drive the refuse vehicle forward when the ejector is transitioning from the first position to the second position in response to the indication of the refuse vehicle entering the geographically indicated location.

12. The refuse vehicle of claim 8 , wherein the processor is configured to provide command signals to drive the refuse vehicle forward when the ejector is transitioning from the first position to the second position in response to the indication of the refuse vehicle entering the geographically indicated location.

13. The refuse vehicle of claim 8 , wherein the processor is configured provide command signals to the actuator to fully extend the actuator only when the processor receives an second indication from a first sensor that the lock is in the unlocked position and a third indication from a second sensor that the tailgate is in the open position.

14. A refuse vehicle, comprising:
a chassis;
a body supported by the chassis and defining a receptacle configured to store refuse therein, the receptacle having a first end and an opposing second end, the receptacle pivotally coupled to the chassis and selectively movable between a first position and a second position, and wherein the second position is angularly offset from the first position;
a lock coupled to the body, wherein the lock is selectively repositionable between a locked position and an unlocked position;
a tailgate positioned at the second end of the receptacle, wherein the tailgate is pivotally coupled to the body and selectively repositionable between an open position and a closed position, wherein the tailgate is configured to be releasably secured in the closed position by the lock;
an actuator coupled to the chassis, wherein the actuator is selectively movable to transition the receptacle between the first position and the second position;
a sensor, wherein the sensor is configured to detect an obstacle;
a processor configured to:
provide command signals to (a) selectively reconfigure the lock into the unlocked position to unlock the tailgate and (b) transition the receptacle from the first position to the second position both in response to receiving a single input to thereby eject refuse from the receptacle without receiving multiple input commands; and
compare a value of the sensor to a predetermined value.

15. The refuse vehicle of claim 14 , wherein the processor is configured to provide command signals to drive
