Abstract: A vehicle such as a truck with a sleeping compartment includes a bed positioned within the sleeping compartment and most preferably at an upper berth position. A bed shifter is provided for shifting the bed between bed sleeping and bed storage positions. More specifically, the upper bed sleeping surface of the bed is raised toward the ceiling of the vehicle when the bed is shifted between the sleeping and storage positions, with the side portions of the bed similarly being raised as this shifting occurs. The bed shifter may be designed to tilt the bed as shifting occurs so that, when in the bed storage position, the upper bed surface more closely follows the contour of a vehicle with a downwardly sloped or otherwise configured ceiling. Bed shifting elements of variable length may be provided to shift the bed by varying the length of these elements.

Abstract: A master clock on a truck maintains vehicle standard time for the purposes of monitoring and recording vehicle performance data throughout the vehicle. Vehicle performance data is stored for a predefined period of time in response to detecting predefined events. Instances of vehicle performance data are time stamped with vehicle standard time. The master vehicle clock can also maintain the local time displayed to the driver. In response to inputs from the driver, the difference between driver local time and vehicle standard time is computed and the updated local time is displayed to the driver.

Abstract: A method for determining installed electronic devices on a truck and for providing a centralized reset to clear faults in the installed electronics. An instrumentation control unit in the cab of a truck determines installed electronics by requesting electronics on a shared data link to transmit data on the data link. The control unit identifies the installed devices from the transmitted data. Data describing the installed devices including manufacturer, model, and installed software can be obtained and displayed for diagnostic purposes. The instrumentation control unit provides a centralized reset for resetting the electronic devices on the data link.

Abstract: A fuel system having a fuel tank for storing a supply of fuel for an internal combustion engine is provided with a fuel recirculation system. Fuel is supplied from the fuel tank to the engine through a supply line and excess fuel is returned from the engine to the tank through a return line. The fuel in the return line is typically warmed as it passes through or in proximity to the engine. A valve is positioned within the fuel tank to sense the temperature of the fuel supplied to the engine and, when the temperature is colder than desired, divert a portion of the warmed return fuel back to the supply line. The diverted fuel helps warm the fuel supplied to the engine and prevent waxing in the fuel system. When the fuel supplied to the engine is not colder than desired, the valve is closed and the warmed fuel is returned to the fuel tank.

Abstract: A support arrangement for an exhaust system including an upright muffler and an upwardly-extending exhaust stack located behind the cab of a truck. An arm is mounted on a frame member of the truck, and a vibration isolator supported on the arm in turn supports the weight of an exhaust pipe elbow, a muffler, and a stack located above the muffler, all oriented generally upwardly. A pair of links are attached to the exhaust stack and to a mounting fastened to the back side of the cab to support the muffler and stack with respect to longitudinal and lateral movement relative to the truck while still permitting vertical movement of the cab relative to the frame.

Abstract: An opening is provided through the front of a truck cab assembly during the manufacture process for allowing access to the interior of the truck cab for installing components therein. The opening most preferably substantially extends from sidewall to sidewall in the horizontal direction, and substantially from the roof structure to the floor structure in the vertical direction. On an assembly line, the front opening is preferably oriented perpendicularly to the direction of travel of truck cabs along the assembly line during a major portion of the vehicle truck cab assembly process. A firewall-dashboard assembly which facilitates easier installation and assembly of certain components is also disclosed. Specifically, the firewall is pre-assembled and combined with a dashboard sub-assembly prior to mounting these components to the truck cab. The firewall-dashboard assembly preferably contains at least the instrument panel, and the brake, clutch, and accelerator mechanisms.

Abstract: A beverage container holder includes first and second beverage container receivers which may be stacked one above the other when stored and also are stacked when positioned in one configuration for use. The container receivers are pivoted about a common upright, most preferably vertical, axis. The upper container receiver includes a rim which defines an opening through which a beverage container may be inserted. The lower receiver defines a recess with a base. The lower receiver may be positioned beneath the upper receiver when in use, in which case the base limits the extent to which a container may be inserted through the rim. The lower receiver includes an upper portion of a first cross-sectional dimension and a lower portion of a smaller cross-sectional dimension, such as sized to receive a standard twelve ounce soda pop container. When in a non-stacked position, the upper receiver is capable of receiving a large beverage container without interference by the lower receiver.

Abstract: A diagnostic method and system in a truck monitors voltages reported by electrical control units in a truck via a shared communication path called the data link. When a data logging unit on the data link detects an event, it persistently stores monitored data measured during a period that may span before and after the event occurred. The voltages measured and reported by electrical control units during this period are used to diagnose electrical wiring problems or other electrical problems in the electrical control units.

Abstract: An aerodynamically designed sun visor with side and front visor portions permit the flow of air upwardly between the vehicle and visor portions.
