  • Patent number: 6324451
    Abstract: A convertible top position sensing system uses rear view mirror mounted compass electronics to detect the position of a convertible top. The sensing system includes a measurement device for measuring a magnetic field intensity, and a filtering module for filtering an artificial magnetic field intensity from the measured magnetic field intensity. The artificial magnetic field intensity is produced by the convertible top. A processing module determines a convertible top position based on the artificial magnetic field intensity. Magnetic field variance information is used in filtering the artificial magnetic field intensity from the measured magnetic field intensity. The sensing system is used in a sound control system for a convertible top vehicle, where a body control module adjusts a radio output parameter such as volume or equalization based on the convertible top position. Using pre-existing compass electronics eliminates the need for additional top position switching components.

  • Patent number: 6323565
    Abstract: A method and apparatus for operating a power liftgate in an automobile, such as a minivan, is disclosed. The invention is comprised in a control system that includes a user input interface for receiving power liftgate actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power liftgate module (PLGM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message, the PLGM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power liftgate activation request. Power liftgate actuation is controlled by the PLGM via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.

  • Patent number: 6318097
    Abstract: The invention relates to a method for monitoring the refrigerant level in an air conditioner, in particular a motor vehicle air conditioner, with a compressor which subdivides the refrigerant circuit into a high-pressure side and a low-pressure side. The method includes the steps of measuring the pressure and the temperature on the high-pressure side at time intervals, determining an assigned temperature using the measured pressure with the aid of a refrigerant-specific function, and determining a refrigerant undercooling value which can be evaluated as a measure of the refrigerant level by subtracting the measured temperature from the assigned one.

  • Patent number: 6318334
    Abstract: A method for reducing hydrocarbon emissions in an engine of a vehicle. The methodology is triggered following the switching off of the ignition by the operator. First, fuel delivery to the engine is terminated. Second, spark ignition is continued based on a predetermined parameter such as time or engine cycles following the termination of the fuel delivery. Last, spark ignition is stopped. Since combustion continues until no fuel exists in the cylinder, there is no over abundance of fuel in the catalyst at a subsequent start up. As such, the catalyst operates effectively at start up and hydrocarbon emissions are lowered.

  • Patent number: 6318345
    Abstract: A fuel control system is provided including a fuel tank and a purge vapor collection canister interconnected with an internal combustion engine. A purge vapor canister vent valve selectively seals the purge vapor canister from atmosphere such that the fuel tank, purge vapor canister, and engine intake manifold form a closed system. Upon a cold engine start, a purge valve disposed between the purge vapor canister and the engine intake manifold is opened such that the pressure differential between the engine intake manifold and the remainder of the system causes fuel vapor collected within the dome portion of the fuel tank to be drawn through the purge vapor canister and into the intake manifold. Simultaneously therewith, the amount of fuel injected by the fuel injectors to the engine is reduced such that a desired amount of total fuel delivery is established.

  • Patent number: 6314813
    Abstract: The vibration damping properties of brake rotors and drums can be represented accurately and repeatably by a single factor obtained from a curve fitting based on an eighth order sine function. A series of test points taken only around one or more vibrational antinodes is used to measure resonant frequencies and vibration decay times around the periphery of a part. This data is then used to determine Q-factors, which are found to vary sinusoidally around an annular brake part.

  • Patent number: 6314802
    Abstract: The present invention provides a method and system for detecting engine misfire with an optimal compensation of the RPM signal in an internal combustion engine in which the data signal containing a plurality of groups of sample data points is generated. Each of the groups of sample data points represents a cylinder firing event. The data signal is then conditioned for misfire detection processing. The data engine cycle compensation vectors for the RPM zone is then multiplied to the sample data of the RPM. Each group of sample data points is processed using signal processing techniques and then mapped into a single mapped data point. The mapped data points are further processed and then compared to a misfire detection dynamic threshold. A misfire detection signal is then output if any of the mapped data points fall outside the dynamic threshold. The misfire detection system achieves high degree of accuracy through a signal processing and statistical detection technology.

  • Patent number: 6314797
    Abstract: A method is provided for detecting a very small leak in an evaporative emission control system of an automotive vehicle. The method includes sealing the evaporative emission control system at a key-off event and monitoring a vacuum switch coupled to the evaporative emission control system for a closing event due to a natural vacuum created in the evaporative emission control system as it cools. If the closing event is not detected, the method determines if a leak detection timer has exceeded a predetermined threshold value. If the timer has exceeded the predetermined threshold value, the method sets a fault code indicating that the very small leak has been detected.

  • Patent number: 6314422
    Abstract: A method is provided for accessing files on a client node which is connected to a server node across a network channel. A first file is displayed on the client node, and context information indicative of this first document is stored. Rather than using a “hard” link which specifies a specific path/filename, a dynamic softlinking process is used to access a second file. A link, similar to a hyperlink, can be selected on the first displayed file to access a second file, where the link includes information indicative of the second file. To determine a file identifier for the second document, a data structure, having a plurality of file identifiers, is accessed using the context information and link information. The second file can then be retrieved from the server node via the network channel using the file identifer and displayed on the client node.

  • Patent number: 6302437
    Abstract: A unique glove box and restraint system including a reaction bracket is provided. The glove box assembly includes a reaction bracket that is attached to a hinge mechanism. The reaction bracket carries a storage bin, a latch, a trim plate, a tether, and a gas source. The gas source is held in an operative relationship with an inflatable air bag. The inflatable air bag is coupled to the trim plate. The trim plate includes an outer panel and an inner attachment plate. The inner attachment plate is selectively coupled to the reaction bracket by a mechanism that disengages when it experiences an outward force greater than a predetermined amount. The latch is connected to the reaction bracket at the end opposing the hinge. During conditions of rapid deceleration, the gas source produces gas to inflate the air bag if electrical current is sent to trigger the gas source by the vehicle crash sensing system.
