Abstract: The example embodiments may relate to a vehicle operator incentive system. In an example, the system may include a vehicle control system having a plurality of controllers, wherein the controllers are configured to communicate diagnostic messages via an internal communication network and wherein each of the diagnostic messages provides information about operation of a vehicle by an operator. The vehicle operator incentive system may include a vehicle diagnostic system communicatively coupled to the internal communication network and configured to: process the diagnostic messages to determine a plurality of measured parameters, award points based on the measured parameters, calculate a score for the operator based on the awarded points, and cause a user interface of the vehicle to display the operator score.

Abstract: A vehicle has an operator cab with a wall defining an interior of the operator cab. An opening is formed through the wall of the operator cab, and a port is connected to the wall of the operator cab around the opening. The port includes a mounting structure connected to the wall and a tube member extending from the mounting structure and defining a passage therein, where the passage of the tube member is aligned with the opening. One or more conduits can then extend through the opening and the passage of the tube member. One or more additional openings may be formed through other portions of the wall of the cab, and each such opening may have a port and/or one or more conduits extending through.

Abstract: A fuel management module for use with a CNG fuel system for a vehicle includes a housing configured to be connected to the vehicle and a number of connections, receptacles, and controls associated with the module. A defueling receptacle may be positioned on the front panel of the housing, for defueling a fuel tank of the vehicle. A defueling control valve may be positioned on the front panel of the housing for controlling operation of the defueling receptacle, allowing for selective defueling. One or more high pressure connections may be accessible on the housing and configured for connection to one or more separate fuel tanks in a plug and play configuration. A plurality of filling connections may be accessible on the housing for filling the fuel tank(s). A low pressure fuel output connection may be positioned on the back panel of the housing to provide fuel output from the high pressure connections to the engine.

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 vehicle has an operator monitoring system that includes an operator sensor configured to sense whether the operator is in a proper operating position within the operator cab and a control module connected to the operator sensor wherein when the vehicle is running and the operator sensor senses that the operator is not in the proper operating position, the control module activates safety features to stop the truck, including any one or a combination of activating the main brake, activating the parking brake, and/or shifting the transmission to a different setting.
