A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

Electric power take-off pump control systems

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.

System and method for electronic power take-off controls

A refuse vehicle includes a chassis, an energy storage device, a body, and an electric power take-off system. The energy storage device (e.g., a battery) is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is configured for storing refuse, and is supported by the chassis. The electric power take-off system is positioned on the body and includes an inverter, an electric motor, and a hydraulic pump that is drive by the electric motor. The inverter receives electrical power from the energy storage device and supplies electrical power to the electric motor. The electric motor drives the hydraulic pump to convert the electrical power into hydraulic power.

Electric power take-off for a refuse vehicle

A refuse vehicle includes a chassis, a battery, a vehicle body, an electric power take-off system, and a lifting system. The chassis supports a plurality of wheels. The battery is supported by the chassis and is configured to provide electrical power to a first motor. Rotation of the first motor selectively drives at least one of the plurality of wheels. The vehicle body is supported by the chassis and defines a receptacle for storing refuse. The electric power take-off system is coupled to the vehicle body and includes a second motor configured to convert electrical power received from the battery into hydraulic power. The electric power take-off system is positioned within the receptacle. The lifting system is coupled to the vehicle body and is movable relative to the receptacle using hydraulic power from the electric power take-off system.

The disconnect is positioned between the battery and the electric power take-off and is configured to selectively decouple the electric power take-off system from the battery.

Control system for a refuse vehicle

In some embodiments, a land vehicle includes sensors that provide information relating to a ride height of the land vehicle. A processing circuit monitors data from the sensors and controls adjustment of one or more vehicle systems that affect the vehicle's ride height based on the data from the sensors. In some embodiments, the processing circuit controls a suspension system and can control the suspension system to have any of a multiplicity of height settings. In some embodiments, the processing circuit controls the ride height based on a user selection of a pre-configured ride height setting. In some embodiments, the processing circuit is configured to maintain a ride height of the vehicle at a consistent ride height when the suspension is unlocked after a load is removed where the suspension was locked after the load was added.

Ride-height control system

An electronic control system may be used to control the steering angle of a vehicle wheel. The electronic control system may be used to determine that a measured speed that a steering angle of a wheel is changing exceeds a threshold speed. The electronic control system may be used to determine that a measured range of motion of the steering angle exceeds a threshold amount. The electronic control system may use an encoder to measure the position of a steering angle of a vehicle wheel.

Steering control system and method

A turret control system and method for a fire fighting vehicle is disclosed. The turret control system includes one or more control modules, such as an envelope control module, turret targeting module, a turret pan module, a turret deploy module, a turret store module. The preferred turret control system also provides improved turret control flexibility and improved operator feedback.

Turret control system based on stored position for a fire fighting vehicle

An electronic control system for a vehicle includes a plurality of input devices, a plurality of output devices, a communication network, and a plurality of interface modules. The plurality of input devices may include a first input device that provides information pertaining to an angular position of a first vehicle wheel. The plurality of output devices may include an actuator capable of adjusting one or both of the angular position of the first vehicle wheel or an angular position of a second vehicle wheel. The plurality of interface modules can be microprocessor based and can be interconnected to each other by way of the communication network. The plurality of interface modules may also be coupled to the plurality of input devices and to the plurality of output devices. The plurality of interface modules may include one or more interface modules that is coupled to the first input device and to the actuator.
