  • Patent number: 6144112
    Abstract: The present invention relates to an apparatus and a method for a motor vehicle security system relating to immobilizing and enabling of a fuel pump for a motor vehicle engine. The system comprises data input means for receiving driver verification data, an engine control unit (ECU) including an ECU processor for controlling engine operation, a pump control unit (PCU) including a PCU processor for controlling the fuel pump, the PCU being separate from the ECU and integrally housed with the fuel pump. Communication links permit communication between the data input means and ECU, and between the ECU and PCU. The ECU processor is activated to control the PCU when valid driver verification data is received. The PCU processor is then activated to communicate a challenge code to the ECU. The ECU and PCU processors then compute respectively a first and a second response code associated with the challenge code.

  • Patent number: 6144312
    Abstract: In a system of wire-bus linked control devices with a reduced bias current requirement, all of the control devices are permanently connected to two bus bars for operational power supply, and the bus bars in turn are connected permanently with the supply poles of an operating current source. One of the control devices is equipped with a standby operating function with prompting readiness, and is continuously active in prompting readiness. Apart from its communications connection with the bus the latter control device has at least one separate signal input through which it can be prompted as well as a control output which, when the normal operating state of this control device is reached (from prompting readiness), can deliver a connect signal. Each of the other control devices has internal control means for controlling its power supply from the two bus bars and a connect control input to which a control signal for activating the internal means can be supplied.

  • Patent number: 6137404
    Abstract: Motorized operating mechanisms for vehicle portal closure members, such as windows, sunroofs, sliding doors, hatches, or convertible tops are common in modern automobiles. Inadvertent operation of such closure members, however, has been known to cause injury and entrapment when such a member is directed to close at an inappropriate moment. A vehicle entrapment prevention system is provided which prevents undesired and possibly injurious operation of such a vehicle portal closure member. Undesired operation often occurs when younger occupants, such as small children, accidentally trigger the operating mechanism, which can cause the closure member to entrap an unsuspecting victim. Such an entrapment prevention system ensures safe operation by determining the presence of a responsible operator through the use of various sensors, and permits operation of a portal closure member only in the presence of such a responsible operator.

Existing central units, in particular vehicle occupant protection systems, featured in most cases separate serial transmission and reception interfaces for the various modules to be connected, causing costs to increase whenever an additional diagnosis module is to be connected. By means of a switchable circuit layout for the interface, this will be connected either to a communication module or to the diagnosis module. The circuit layout is particularly simple and space-saving, being set up by means of diode switches, and preferably features a potential tapping point for automatic switchover into diagnosis mode.

The dialogue can be moved in a second dimension by turning the rotary switch which is in a second axial position. The selected functions or groups of functions can be called by another switch. A device feeds back the selected functions or groups of functions optically, acoustically, and/or haptically.

  • Patent number: 6100602
    Abstract: A process for replacing a multi-functional original installed harness for a harness or cable for a mobile vehicle in a efficient and time saving manner. More specifically, the procedure involves: (i) identifying the critical electrically engaged components engaged to a multi-functional original installed harness for an engine that requires replacement; (ii) disconnecting the original installed electrical harness from only those critical components; (iii) running an electrical service overlay harness physically adjacent to the original harness; and (iv) engaging the critical components to the service overlay harness. This triage-like repair saves a significant amount of time and effort.

  • Patent number: 6091162
    Abstract: A method and apparatus for operating a power sliding door 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 sliding door actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power sliding door module (PSDM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message the PSDM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power sliding door activation request. Power sliding door actuation is controlled by the PSDM via electric motors located at or near the power doors. A power liftgate module (PLGM) controls the power liftgate actuation upon via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.

  • Patent number: 6088643
    Abstract: A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level.
