  • Publication number: 20060282214
    Abstract: A system and method of intelligent navigation of a vehicle using a navigation system with artificial intelligence is provided. The system includes a global positioning means, a navigation means, a controller, and an information database containing a map of a location of a traffic control device. The method includes the steps of maintaining a map in an information database associated with the navigation system, and sensing a location of the vehicle using an input means in communication with the navigation system. The method also includes the steps of determining if the sensed vehicle location is identifiable on the map maintained by the information database and updating the map using the sensed vehicle location if not identifiable; and determining if the vehicle is approaching an identifiable traffic control device using the map in the information database and the sensed vehicle location, if the sensed vehicle location is identifiable.

  • Patent number: 7140358
    Abstract: An oil separator that removes oil from ventilation gases flowing between a crankcase and an intake manifold of an internal combustion engine. The oil separator includes a housing, a wall and a diaphragm. The housing has an inlet and an outlet. The wall is cooperative with the housing to define a path through which the gases flow between the inlet and the outlet. The wall is movably coupled to the housing to effect a change in the height of the path. The diaphragm has a movable portion coupled to the wall. The diaphragm defines a substantially closed volume. The volume is open with the intake manifold so that pressure changes in the intake manifold causes corresponding displacement of the movable portion and the wall relative to the housing.

  • Publication number: 20060260589
    Abstract: An oil separator that removes oil from ventilation gases flowing between a crankcase and an intake manifold of an internal combustion engine. The oil separator includes a housing having an inlet and an outlet. The housing includes a guide wall having a plurality of holes to allow gases to flow therethrough between the inlet and the outlet. A plate is movably coupled to the housing for movement between a closed position blocking the flow of gases through the holes in the guide wall and an open position spaced apart from the guide wall to allow gases to flow through at least one of the holes in the guide wall. A diaphragm has a movable portion coupled to the plate. The diaphragm defines a substantially closed volume continuous with the intake manifold so that pressure changes in the intake manifold causes corresponding displacement of the movable portion and the plate relative to the housing.

  • Patent number: 7130745
    Abstract: An apparatus for facilitating avoidance of a vehicle collision with an object, comprises a vision sensor providing image data, and an image analyzer, operable to provide an estimated time to collision of the vehicle with the object. The estimated time to collision is determined from a rate of expansion of an image element corresponding to the object within the image data, and the apparatus provides a warning if the estimated time to collision is less than or approximately equal to a predetermined time.

  • Publication number: 20060142917
    Abstract: The present invention is operative to disable at least one infotainment device under certain conditions relative to the current driving environment of the user. The system uses a weighted matrix to assign risk to certain sensed conditions while driving. A changed condition is assigned a weight and the weighted risks are summed to calculate risk level information. The risk level information is thereafter compared to priority level information associated with at least one infotainment device. When the risk level information exceeds or is equal to the priority level information of the at least one infotainment device the system temporarily disables the infotainment device until the driving environment changes to a condition where it is safe to operate the infotainment device.

  • Patent number: 7047944
    Abstract: The present invention provides a method for computer controlled fuel injection into a vehicle engine under conditions where the vehicle is starting from cold or being restarted after a short period of being shut off. The method utilizes the value of conductance measured at an air/fuel sensor heater and t least one other engine parameter to determine the correct amount of fuel to be injected into the engine to accomplish efficient combustion. The computer controller adjusts the amount of fuel to be delivered from the fuel injector into the engine based on the value of conductance.
