Abstract: Environment conditions expected to be encountered by a vehicle are used as inputs in determining operating modes of a motive power system of a plug-in hybrid electric vehicle. A vehicle operating in charge depleting mode may transition to operate in charge sustaining mode if the vehicle is expected to encounter circumstances where it is desirable to allow the vehicle to more quickly respond to sudden requests for torque.

Abstract: A system and method of controlling a vehicle with a trailer comprises determining the presence of a trailer, determining a vehicle velocity, determining a steering wheel angle, and determining a rear axle side slip angle. When the rear axle side slip angle is above a predetermined value, the vehicle velocity is above a velocity threshold, and the steering wheel is about zero, brake-steer is applied to the vehicle.

Abstract: A method of controlling an automotive vehicle having a turning radius includes determining a hand wheel torque and applying brake-steer as a function of hand wheel torque.

Abstract: A night vision system for a vehicle includes a pulsed light source for illuminating a region proximate the vehicle and a secondary trigger light source operating at a predetermined pulse timing and second wavelength. A light sensor detects light at the second wavelength. The trigger light pulses are used to indicate the pulse timing of each respective vehicle's primary NIR light source. Upon detecting another vehicle's trigger light source, the controller adjusts the pulse phase of the first light source to be exactly out-of-phase with that of the oncoming vehicle since the pulsed timing of the oncoming vehicle's NIR light source is known upon detection of the opposing vehicle's trigger light source. Each vehicle can then adjust its primary light source to be out-of-phase with the other vehicle and, hence, non-interfering.

Abstract: A micro-machined accelerometer includes a moveable metal plate, mounted upon a semiconductor substrate. The moveable metal plate includes an aperture which contains a pedestal and at least one torsion bar for connecting the pedestal to the moveable metal plate. Measurement electrodes formed on the semiconductor substrate combine with the metal plate to form measurement capacitors. A combined self-test/common electrode provides a dual function of a common electrode during operation of the accelerometer and a testing electrode during a self-test procedure.

Abstract: A power turbine/flywheel assembly for use in a dual shaft turbine engine having a compressor and a gasifier coupled to a first shaft. The assembly includes a second shaft that is uncoupled from the first shaft and is allowed to rotate independently of the first shaft. First and second power turbine blades are attached concentrically about and are directly coupled to the second shaft. A flywheel is directly attached concentrically about the second shaft. The flywheel is positioned between the first and second turbine blades. The first and second power turbine blades and the flywheel rotate as a unit about the second shaft.

Abstract: A capacitive-type torsion beam accelerometer sensor element exhibiting improved stability contains slots in the heavy side of the rotatable sensing element which serve to alter the geometry of the heavy side capacitor such that the electrical geometry substantially coincides with the physical geometry of the substrate's fixed conductive plate in the presence of charge spreading. The slots also permit ingress and egress of air, thus extending the frequency response.

Abstract: A mass air flow sensor (MAFS) is disclosed wherein silicon members carrying a resistive film are bonded to a glass substrate and extend out over an air flow opening through the glass substrate. The silicon members may be either bridges across the air flow opening or cantilevered beams having one end bonded to the substrate and a second free end. Silicon frames around the air flow opening can also be provided, to which an environmental seal can be formed. A novel method of making such sensors includes providing the glass substrate with the air flow opening therethrough and aligning thereover a silicon wafer selectively passivated to define the silicon member(s) and any frame element. The glass and silicon wafers are bonded and subsequently anisotropically etched, after which the resultant bonded and etched assembly can be employed in accordance with known mounting techniques.

Abstract: A micromachined mass air flow sensor comprises a silicon substrate with an air flow opening formed therethrough. One or more silicon members carrying a thin film resistor extend over the air flow opening. The silicon members are thermally isolated from the silicon substrate frame about the air flow opening by thermal isolation zones of porous silicon oxide.

Abstract: A semiconductor accelerometer having a sensor element supported by a pedestal coupled to a substrate. Coupling between the pedestal and the sensor element includes opposing torsion beams along the axis of flexure coupled through a spring to the pedestal. The spring includes a pair of beams extending in a direction perpendicular to the torsion beams so that thermal expansion applies a tensile force to the torsion beams.
