  • Patent number: 9481335
    Abstract: An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.

  • Publication number: 20080231027
    Abstract: System and methods are provided for classifying an occupant of a vehicle. An edge image generation component (102) produces an edge image of a vehicle occupant. A long term filtering component (104) filters across a plurality of edge images to produce a static edge image. A feature extraction component (106) extracts a plurality of features from the static edge image. A classification component (108) selects an occupant class for the vehicle occupant according to the extracted plurality of features.

  • Patent number: 7363184
    Abstract: A method (60) for adjusting a sensed load W(s) of a vehicle seat weight sensing system (10) includes the step (64) of determining a rate of change {dot over (W)}(t),{dot over (W)}avg in the sensed load. The method (60) also includes the step (66) of determining the likelihood of drift in the sensed load W(s) in response to the determined rate of change {dot over (W)}(t),{dot over (W)}avg.

  • Patent number: 7216557
    Abstract: A method and apparatus (40) for testing an occupant position sensing system (12) of a vehicle (10) includes a motor (42) having a stationary portion (44) and a movable portion (46). A test object (90) is fixed relative to the movable portion (46) of the motor (42). A motor position sensor (64) senses a position of the movable portion (46) of the motor (42) relative to the stationary portion (44) and for providing a motor position signal indicative thereof. Motor drive electronics (58) are responsive to the motor position signal for controlling the motor (42) for moving the test object (90). A data recorder (80) is adapted to receive and record data from the occupant position sensing system (12) and is adapted to receive and record the motor position signal provided by the motor position sensor (64).

  • Patent number: 7111869
    Abstract: An apparatus and method for controlling an actuatable occupant protection system (40) in a passenger compartment (12) of a vehicle (10) includes a camera (72) configured for obtaining an image of a viewable field (78) within the passenger compartment (12) of the vehicle (10). At least one pattern (84, 86) is associated with vehicle structures (22, 24, 26) located within the viewable field (78). The portions of the obtained image associated with vehicle structures (22, 24, 26) having the pattern (84, 86) are removed from the image so as to obtain information regarding occupancy of the viewable field (78). The actuatable occupant protection system (40) is controlled in response to the obtained occupancy information.

  • Patent number: 6459655
    Abstract: An apparatus (20) determines a target (e.g., a vehicle occupant 22) beyond a predetermined distance. In an exemplary embodiment, the apparatus (20) determines a distant target for use in control of air bag deployment. The apparatus (20) includes a sensor (44) for emitting and receiving first (52, 56) and second (54, 58) signals in an interspersed predetermined emission sequence toward the target. A controller (60) successively determines a time interval between the emission of a current signal and the reception of an echo. The controller (60) successively compares at least two time intervals to determine whether a sufficient difference exists to indicate that the target is beyond the predetermined distance and outputs a signal to the air bag actuation system (62).
