Further, the change management system may be configured to act as a virtual user when interfacing with one or more of the engineering subsystems. Additionally, the change management system may be configured to check data from one or more of the subsystems for compliance with one or more control rules governing the progression of a manufacturing/design project.

Abstract: A heavy-duty truck chassis has a frame assembly having a first rail spaced from a second rail to define a gap therebetween. A front axle is supported by the frame assembly and is positioned proximate a front portion of the frame assembly. A rear axle is supported by the frame assembly and is positioned proximate a rear portion of the frame assembly. A fuel tank is supported by the frame assembly and positioned in the gap and behind the rear axle.

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 vehicle that includes a chassis, wheels, a drivetrain including an engine and a transmission, and a brake system. The vehicle also has a vehicle control system that includes controllers for the engine, the transmission controller, and the brake system, a vehicle network connected to the controllers to permit communication to and from these components, and a primary vehicle controller connected to the network and configured to communicate with the controllers. The vehicle further includes a vehicle diagnostic system that is connected to the network and configured to communicate with the various controllers. The diagnostic system is configured to operate in a diagnostic mode, in which the diagnostic system is configured to display diagnostic information from one or more of the controllers. The diagnostic system may further be configured to operate in a display mode, where the vehicle diagnostic system is configured to display operating information regarding the vehicle.

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: An air intake assembly for a vehicle includes an air intake configured to intake ambient air and a heater box configured to be positioned adjacent a component of an exhaust assembly of the vehicle.
