A refuse vehicle includes a chassis supporting a plurality of wheels, a battery supported by the chassis and configured to provide electrical power to a first motor, and an electric power take-off system coupled to the vehicle body. The electric power-take-off system includes a second motor configured to convert electrical power received from the battery into hydraulic power, an inverter configured to provide electrical power to the second motor from the battery, a heat dissipation device coupled to the inverter, a first sensor configured to detect thermal energy within the inverter, and a controller configured to receive data from the first sensor and provide operating parameters to the heat dissipation device, wherein the controller is further configured to determine if the data from the first sensor is greater than a critical operating condition and shut down the electric power take-off system in response.
REFUSE VEHICLE WITH ELECTRIC LIFT
A fully-electric lift assembly for a refuse vehicle includes a track, a carrier, and a push chain. The track includes multiple channels that extend along an entire length of a path of the track. The carrier is configured to translate along the path of the track. The carrier includes multiple slidable members, each slidable member configured to engage the track at a corresponding one of the channels. The push chain is configured to couple with the carrier at a first end and be driven by an electric motor. The push chain is configured to exert a pushing force on the carrier to drive the carrier to ascend along the track.
VEHICLE CAMERA AND LIGHT PROJECTION SYSTEMS
A refuse vehicle including a chassis, a tractive element coupled to the chassis and configured to engage a support surface to support the refuse vehicle, a refuse compartment coupled to the chassis, a lift assembly coupled to the chassis and configured to lift a refuse container to transfer refuse from the refuse container into the refuse compartment, and a light projector coupled to the chassis and positioned to emit a light onto the support surface to define a target area. The target area represents a range of positions within which the lift assembly is capable of engaging the refuse container.
Refuse vehicle with electric reach apparatus
A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.
Refuse vehicle control systems
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.
HYBRID ELECTRIC HYDRAULIC REFUSE VEHICLE
A refuse vehicle includes a vehicle body on a chassis having a frame, an internal combustion engine (ICE), and a transmission coupling the ICE with a plurality of tractive elements. The vehicle body includes an electrically powered body system and a hydraulically powered body system. A first power module is coupled with the ICE and is configured to provide rotary power to a hydraulic pump that is configured to provide hydraulic power to the hydraulically powered body system. A second power module is coupled with the transmission and configured to rotationally couple and decouple an electrical generator with the transmission. The generator is configured to charge at least one battery when rotationally coupled with the transmission. The battery is configured to provide electrical power to the electrically powered body system.

A refuse vehicle includes a battery configured to provide electrical energy to drive at least one of a plurality of wheels, a vehicle body supported by the chassis and defining a receptacle for storing refuse therein, and an electric power take-off system including a motor configured to power to a hydraulic system in response to receiving the electrical energy from the battery, an inverter configured to provide the electrical energy to the motor from the battery, a sensor configured to detect thermal energy within the inverter, and a controller configured to receive data from the sensor, wherein the controller is further configured to determine if the data from the sensor is greater than a critical operating condition and reduce a rate of electrical energy supplied to the motor in response to determining that the data from the sensor is greater than the critical operating condition.
Refuse container engagement
A refuse collection vehicle includes a grabber that is operable to engage a refuse container, at least one sensor that is arranged to collect data indicating a relative positioning of a first arm of the grabber and a second arm of the grabber, and a controller having one or more control elements for selecting a target positioning of a first arm of the grabber and a second arm of the grabber. The first arm and the second arm automatically move to the target positioning in response to a signal received by an onboard computing device of the vehicle.
REFUSE VEHICLE CONTROL SYSTEMS
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.
PUMP CONTROL SYSTEM FOR A REFUSE VEHICLE
A refuse vehicle includes a chassis, a body, a lift system, and a controller. The lift system includes a lift arm actuator, a pump, and an electric motor. The pump is configured to power the lift arm actuator and is driven by the electric motor. The controller is configured to receive a user input that specifies a position of the lift arm actuator within a movement range, determine a flow demand required to move the lift arm actuator to the position, determine a motor speed that satisfies the flow demand, and communicate the motor speed to the electric motor.
