  • Patent number: 7021128
    Abstract: A misfire detection system is provided including an internal combustion engine having a combustion chamber and an exhaust system in fluid communication with the combustion chamber. An acoustic sensor is associated with either the combustion chamber or the exhaust system for sensing noise. The controller receives a signal from the acoustic sensor for determining whether the noise is indicative of misfire. One or more acoustic sensors may be fluidly and/or mechanically coupled to the engine or other portion of the powertrain system. The acoustic sensor generates a signal having a frequency that may be compared to engine temperatures, speeds, and loads to determine whether a misfire event has occurred in one of the cylinders. The signature of the frequency may be determined and compared with a known set of frequencies for desired engine operation to determine whether a misfire has occurred.

  • Patent number: 6964694
    Abstract: A particulate filter system is provided including an exhaust system transporting emissions from an engine. A filter such as a diesel particulate filter is disposed in the exhaust system. An acoustic sensor is associated with the exhaust system for detecting one or more frequencies passing through the filter. The frequency corresponds to a filter state indicative of a clean, full, loading, or failed filter. One or more acoustic sensors may fluidly or mechanically coupled to portions of the exhaust system to determine the frequency caused by the exhaust flow through the filter. The acoustic emissions from the filter may be used to compare to a known filter state to determine the present filter state. Alternatively, more sophisticated mathematical approaches may be used in which processed filter information is compared to a known filter state to determine the present filter state.

  • Patent number: 6947575
    Abstract: An apparatus (30) and associated method determine a vehicle occupant characteristic. An imager (32) collects a first image of an occupant location while the occupant location is subject to a first lighting condition. A light source (38) provides light onto the occupant location. The imager (32) collects a second image of the occupant location while the occupant location is subject to the first lighting condition and the provided light. A subtractor device (50) generates a third image of the occupant location indicative of the difference between the first and second images. An image processing device (52) processes the third image to determine the vehicle occupant characteristic.

  • Patent number: 6914526
    Abstract: A vehicle intrusion detection system (10) for detecting an intrusion condition of a vehicle (12) having an occupant compartment (14) partially defined by an outer structure (30) of the vehicle, comprises an actuatable illuminator (40) mounted in the vehicle and having a limited field of illumination (52) extending within the vehicle occupant compartment adjacent the vehicle outer structure. A linear imager (60) mounted in the vehicle (12) has a field of view (62) that substantially coincides with the field of illumination (52) of the illuminator (40). A controller (70) compares a first image taken by the imager (60) when the illuminator (40) is actuated and a second image taken by the imager when the illuminator is unactuated to help determine the existence of an intrusion condition of the vehicle.

  • Patent number: 6810133
    Abstract: An occupant sensing system (12) and an associated method provide for the sensing of an occupant (14). An illuminating element (46) of the system (12)selectively illuminates the interior of a vehicle (8). An image sensor (50) acquires a first image of the interior of the vehicle (8) when the interior of the vehicle is illuminated by ambient sources only and acquires a second image of the interior of the vehicle when the interior of the vehicle is illuminated by ambient sources and the illuminating element (46). A controller (34) removes the effect of ambient sources by comparing the first and second images to produce a third image of the interior of the vehicle (8) as illuminated by the illuminating element (46) only. The controller (34) determines the presence of an occupant (14) by comparing the third image to a produced map of the interior of the vehicle (8).

  • Patent number: 6781676
    Abstract: An apparatus (12) for determining the location of a vehicle occupant (20) in a vehicle interior includes a light source (40) for projecting at least one structured light beam (42) onto an area of interest (44) to form a light pattern on the area of interest. A beam divergence control device (50) alters the apparent location of the light source (40) with respect to the area of interest (44). An imager (60) detects the light reflected from the area of interest (44). A characteristic of the reflected light is measured, and the distance between the imager (60) and the area of interest (44) is measured, based on the measured characteristic of the reflected light.

  • Patent number: 6578869
    Abstract: A vehicle occupant sensor apparatus (34) has an imager (36) that gathers an image of an occupant (12). The image has focus attributes. A focal plane associated with the imager (36) is at a distance from the imager. A 2D high-pass filter (42), a multiple frame temporal filter (46), and a position determination component (52) operate to determine position of the occupant (12) relative to the focal plane (38) via use of the focus attributes.

  • Publication number: 20030038722
    Abstract: A system (10) has a portion (e.g., 30, 42 and 44) for sensing the presence of a person in a vehicle interior compartment (e.g., 20). The system (10) also has a portion (e.g., 34 and 50) for determining if the temperature in the vehicle interior compartment (20) is potentially dangerous to the person. The system (10) further has a portion (e.g., 60, and 66, 68, 70, or 72) responsive to the determination of potentially dangerous temperature for providing aid to the person in the vehicle interior compartment (20). An associated method includes sensing the presence of a person in a vehicle interior compartment, determining if a temperature condition exists in the vehicle interior compartment that is potentially dangerous to the person, and providing aid to the person in the vehicle interior compartment in response to the determination.
