Abstract: A cruise control system for a vehicle having an engine and a power take-off throttle control capable of controlling the speed of the engine includes a cruise control device in communication with a speedometer of the vehicle and the power take-off throttle control. The cruise control device includes a processor configured for receiving a user selection of a set ground speed, determining a current ground speed of the vehicle, via communication with the speedometer, comparing the current ground speed with the set ground speed, and taking further action to maintain the current ground speed close to the set ground speed. The further action taken by the processor may include transmitting an acceleration signal or deceleration signal to the power take-off throttle control to increase or decrease a speed of the engine if the current ground speed is determined to be lower or higher than the set ground speed.

Abstract: A system configured for use with a vehicle includes a trailer connection mechanism configured to be mounted on the vehicle and including a release actuator configured to release the connection between the trailer connection mechanism and a trailer, a release assembly connected to the release actuator and configured to cause the release actuator to release the connection between the trailer connection mechanism and the trailer upon receiving user input, and an anti-release mechanism connected to the trailer connection mechanism. The anti-release mechanism is configured to detect statuses of a transmission and a brake system of the vehicle, and to selectively permit or prevent operation of the release actuator to release the connection between the trailer connection mechanism and the trailer based on the status of at least one of the brake system and the transmission.

Abstract: A vehicle (10) such as a heavy-duty truck (10) has an operator cab and a body section. The truck (10) has controls that control operating parameters associated with the operator cab and controls that control operating parameters associated with the body section. The truck (10) has a control system (12) that integrates the controls for the operator cab and the controls for the body section.
