Abstract: A hydraulic lash adjuster for an engine is provided that includes a resilient seal received over a plunger assembly above a fluid return aperture in the plunger body. The hollow interior of the pushrod which supplies the hydraulic lash adjuster with fluid provides a secondary low pressure fluid cavity which allows the overall length of the hydraulic lash adjuster to be shortened, thus removing mass from the valve train and improving the valve train dynamics. This configuration prevents fluid from escaping the lash adjuster, allowing the lash adjuster to be positioned in the engine over a wider range of operating angles. Supplying fluid from the pushrod also eliminates the need to machine a fluid supply bore into the body of the hydraulic lash adjuster as well as the need to orient the fluid supply bore to a fluid gallery in the engine block.

Abstract: A self docking instrument panel connector system is provided with a first connector member (18) attached to an instrument panel assembly (12). A second connector member (20) is attached to a body of a vehicle (16) and is designed to mate with the first connector member (18). One of the connector members (20) is adjustably supported to be movable in first and second lateral directions and in a longitudinal direction in order to accommodate for build tolerances and component insertion variances.

Abstract: A magnetic striker alignment fixture for aligning a striker with a latch on a door jamb, and a method of use therefor, is described. The fixture includes a substantially planar base of rigid material having an area defining an aperture sized to tightly receive the striker and position the striker in the plane parallel to the base. At least one magnet is disposed on at least one surface of the base so as to hold the base adjacent to the door jamb, with the base being parallel to the door jamb thereby positioning the striker on the door jamb and restricting motion of the striker in the plane of the surface of the door jamb. Optionally, a handle can either be pivotally attached to the base or formed on a surface of the base, so as to permit the fixture to be easily removed from the door jamb. Additionally, an optional elongated member extending from at least one surface of the base can be provided to function as a locator pin and anti-rotation device.

Abstract: In accordance with this invention, a security feature that protects against theft of compact discs (“CDs”) left in a compact disc player in a vehicle is implemented in a conventional compact disc player that has a CD insertion/ejection servo mechanism, a controller that controls the compact disc player including the insertion/ejection servo mechanism, and an eject switch coupled to the controller. The controller is configured so that it knows the state of the ignition switch, typically from a signal or data from a controller in the vehicle, such as a body controller, engine controller or transmission controller. The controller senses whether the eject switch is actuated when the ignition switch is turned from off to on. Each time that the controller senses that the eject switch is actuated when the ignition switch is turned from off to on, the controller transitions between a security off state and a security on state.

Abstract: A vehicle occupant restraint system having a base system and a supplemental system is provided. The base system includes an air bag module and an occupant restraint controller. In the absence of the supplemental system, the occupant restraint controller operates in a default mode wherein the air bag module is enabled. Coupling the supplemental system to the base system permits the air bag module to be selectively disabled. The supplemental system transmits a plurality of signals to indicate whether the air bag module is to be disabled or enabled. When the occupant restraint controller receives a signal indicating that the air bag module is to be disabled, the occupant restraint controller inhibits the generation of squib pulses which would cause the air bag module to actuate.

Abstract: In a method to avoid bucking oscillations during acceleration of vehicles, the engine torque is varied. To reliably prevent bucking oscillations without adversely affecting the acceleration behavior and exhaust behavior, it is proposed that during operation of the gas pedal, the engine torque be varied according to a stipulated engine torque curve between a lower torque value and an upper torque value, in which the engine torque curve has a local maximum adjacent to the lower torque value and has a local minimum between the local maximum and the upper torque value.

In a first mode, the upper and lower members are rigidly interconnected and the closure panel assembly is permitted to pivot about an upper pivot axis adjacent an upper edge of the upper member. In a second mode, the upper and lower members are free to move relative to one another. The upper member is permitted to independently pivot about the upper pivot axis. The lower member is permitted to independently pivot about a lower pivot axis adjacent a lower edge of the lower member.

Abstract: A computerized method diagnoses a vehicle temperature sensor. The method includes the steps of verifying a fault status for the sensor, and initializing a mileage based diagnostic when the default status indicates that no sensor faults are present. The mileage based diagnostic is conducted on the sensor upon initialization. The mileage based diagnostic is conducted by calculating a change in temperature and comparing the change in temperature to a predetermined temperature change. A change in mileage is also calculated and compared to a predetermined mileage change. The mileage based diagnostic further includes comparing a number of warmups for the vehicle to a predetermined number of warmups. The sensor is failed when the change in mileage reaches the predetermined mileage change, the number of warmups reaches the predetermined number of warmups, and the change in temperature does not reach the predetermined temperature change.

Abstract: A dynamic control system for a power-assist device has a statics formulator for determining a set of static torques for the lift system based on force data from the lift system. The control system further includes a dynamics formulator for determining a set of dynamic torques for the lift system based on joint data and the static torques. A static torque and a dynamic torque is therefore determined for each joint of the assist device. The control system also includes a torque summation module for summing the dynamic torques with the static torques to determine torque data for each joint of the lift system. The torque summation module applies the torque data to the lift system to achieve dynamic compensation within a substantially shorter response time. Thus, a method and system are presented for dynamically controlling a power-assisted lift system to continuously reduce human operator strain in a real-time mode.

A lock mechanism is coupled with the latch mechanism to prohibit unauthorized disconnection of the male and female connectors in a coupled position.

Abstract: In a method to avoid bucking oscillations during acceleration of vehicles the throttle valve position is influenced, in which, for conversion of engine torque trend between the lower torque initial value and an upper torque target value, the trend of the throttle valve position is changed between an initial closed position corresponding to the torque initial value and a target opening position corresponding to the torque target value. To prevent bucking oscillations reliably without adversely affecting the acceleration behavior and exhaust behavior, the trend of the throttle valve position adjacent to the initial closed position has a local maximum that opens the throttle valve and a local minimum that closes the throttle valve between the local maximum and the target opening position.
