Abstract: A diagnostic tool for an auxiliary power unit comprising an alternating current generator having an exciter winding and an output winding and an automatic voltage regulator for providing control over the excitation winding of the generator includes a harness with plug connectors allowing the diagnostic tool to be directly introduced between the generator and automatic voltage regulator replacing the conventional connections without affecting operation of the auxiliary power unit. The diagnostic tool has a plurality of multimeters between the automatic voltage regulator and the alternating current generator providing voltage readings across and resistance readings for the generator's stator exciter winding and main and auxiliary output windings. A protocol relates voltage and resistance readings taken with the multimeters when the auxiliary power unit is on and off to possible faults in the generator or with the automatic voltage regulator.

The airbrake reservoir lock system comprises a primary air reservoir, and a first airbrake reservoir lock. The primary air reservoir has an input port and an output port. The primary air reservoir stores an amount of pressurized air. The first airbrake reservoir lock is disposed in fluid communication with the output port of the primary air reservoir. The first airbrake reservoir lock has a valve portion and an electrical actuator. The valve portion has an open position and a closed position. The electrical actuator positions the valve portion of the first airbrake reservoir lock between the open position and the closed position based upon an output of the electronic control module.

Abstract: An automatically adjusting side mirror assembly for a vehicle having an eye gaze detection system has a mirror subassembly, a support bracket, an actuator mechanism and a biasing mechanism. The mirror subassembly has a first and second position. The second position aligns the mirror subassembly generally parallel to the vehicle in order to provide better aerodynamics. The support bracket connects to the vehicle. The mirror subassembly is connected to the support bracket. The actuator mechanism and the biasing mechanism each connects to the mirror subassembly. The actuator mechanism has a first and second position corresponding to the first and second position of the mirror subassembly. The actuator mechanism is in electrical communication with the eye gaze detection system to position the mirror subassembly to the first position in response to an output of the eye gaze detection system. The biasing mechanism biases the mirror subassembly to the first position.

Abstract: Dissolving paper (22) covers pressure sensitive adhesive (20) on a mounting face (18) of an object (16) to be mounted on an exterior surface of a body panel (10) of a motor vehicle by a mechanical fastening system (24). The mounting is exposed to a water wash. Water begins to be absorbed by the dissolving paper through the edge of the paper's outer perimeter. As the paper increasingly absorbs water, it dissolves in the water exposing the adhesive which then adheres to the panel.

Abstract: A frame member for a frame assembly of a vehicle includes a first outer steel layer, a second outer steel layer and an aluminum core layer between the first outer steel layer and the second outer steel layer. The first outer steel layer, the second outer steel layer and the aluminum core layer are metallurgically bonded together.

Abstract: A highway tractor (12) has a fifth wheel (28) to which a trailer (14) that is to be towed by the tractor can be coupled. A positioning system sets fore-aft position of the fifth wheel on the tractor. The positioning system (FIG. 2; FIG. 3) has a positioning mechanism for moving the fifth wheel fore and aft on the tractor and a controller for processing certain data that is used to cause the positioning mechanism to move the fifth wheel to a fore-aft target position on the tractor.

Abstract: An EGR control method to prevent condensation within the EGR system uses a temperature sensor signal from an EGR cooler exhaust gas outlet to model or estimate exhaust manifold gas temperature upstream of the cooler. If the estimated exhaust manifold gas temperature falls below a predetermined level, the engine control system closes or partially closes the EGR control valve to stop EGR flow through the cooler and the EGR valve.

Abstract: A motor vehicle operator interface and control algorithm convey diesel particulate filter regeneration status to the operator. The algorithm also allows new control over heretofore automatic regeneration, through limiting the inhibit function. The DPF after-treatment operator interface provides multiple status indications to the operator. In a preferred embodiment this is effected using a switched indicator lamp.

Abstract: In a pneumatic brake system for a motor vehicle, a variable speed electric motor is connected to a high voltage direct current power supply for variable energization, thus varying the operating rate of a compressor and the rate of pressurization of the brake system storage tanks. The operating rate of the compressor is varied responsive to pressure readings taken from the storage tanks during pressurization to minimize energy consumption.

Abstract: Redundant power supplies and redundant channels of communication maximize the probability that a controller will trigger a battery disconnect switch to open when commanded to do so.

Abstract: An exhaust gas turbine generator system for a vehicle that has an internal combustion engine with an exhaust system is provided. The exhaust system comprises a turbine, an electrical generator, a waste gate, and an electronic control module. The turbine is disposed in fluid communication with an exhaust gas system of an internal combustion engine to allow fluid flow between the turbine and the exhaust gas system. The electrical generator connects to the turbine. The waste gate is disposed in fluid communication with the exhaust gas system of the internal combustion engine. The waste gate is positionable between an open position and a closed position in response to an output signal from the electronic control module. The fluid flow in the exhaust gas system to the turbine is reduced when the waste gate is positioned to the open position.

Abstract: Embodiments comprise a stackable vehicle which may be supported from, or serve as support to, another like vehicle. The vehicle includes a frame and a body supported from the frame. The body includes a weight bearing roof. Wheel assemblies are mounted for rotation on the frame. The body includes recesses from the roof of the body to accommodate location of wheel assemblies of a like vehicle supported on the roof. Support and mounting points are located on the roof and on the frame respectively to fix location of a vehicle to be carried on top of a supporting vehicle.

Abstract: An anti-separation device for use with an isolator that couples a steering input shaft and a steering gear connector includes a retaining plate and a retaining formation. The retaining plate is coupled to the steering gear connector and is configured to displace with and torque with the steering gear connector. The retaining formation is coupled to the steering input shaft and is configured to displace with and torque with the steering input shaft. When the isolator fails and the steering input shaft displaces or rotates relative to the steering gear connector, the retaining plate limits the relative displacement or rotation of the retaining formation and couples the steering input shaft to the steering gear connector.

Abstract: A method of starting an internal combustion engine of a vehicle with a hybrid-electric powertrain having an internal combustion engine, a generator, and a high-voltage battery pack, is provided. An internal combustion engine start input signal is received. A load on an electric motor and generator is determined. The internal combustion engine receives torque transmitted from the electric motor and generator when the load on the electric motor and generator is below a predetermined load threshold. The internal combustion engine receives torque from an exogenous starting device when the load on the electric motor and generator is above the predetermined load threshold.
