Filed:

Oct 4, 2000

Appl. No.:

09/679172

Inventors:

Edward J. Gillis - South Lyon MI
Stephen R. W. Cooper - Fowlerville MI
Raymond J. David - Dearborn Heights MI

Assignee:

TRW Inc. - Lyndhurst OH

International Classification:

G01S 1500

US Classification:

367 96, 367 99, 701 45

Abstract:

An apparatus ( ) determines a target (e. g. , a vehicle occupant ) beyond a predetermined distance. In an exemplary embodiment, the apparatus ( ) determines a distant target for use in control of air bag deployment. The apparatus ( ) includes a sensor ( ) for emitting and receiving first ( ) and second ( ) signals in an interspersed predetermined emission sequence toward the target. A controller ( ) successively determines a time interval between the emission of a current signal and the reception of an echo. The controller ( ) 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 ( ). The controller ( ) also performs a distance calculation to the target using at least one of the time-of-flight periods of the first and second signals, where the first time-of-flight period occurs between emission and echo reception of the first signal and where the second time-of-flight period occurs between emission and echo reception of the second signal, and outputs a signal to the air bag actuation system ( ).

International Classification:

B60R 21/32

US Classification:

280735, 701 45, 382103

Abstract:

An apparatus and method for controlling an actuatable occupant protection system () in a passenger compartment () of a vehicle () includes a camera () configured for obtaining an image of a viewable field () within the passenger compartment () of the vehicle (). At least one pattern () is associated with vehicle structures () located within the viewable field (). The portions of the obtained image associated with vehicle structures () having the pattern () are removed from the image so as to obtain information regarding occupancy of the viewable field (). The actuatable occupant protection system () is controlled in response to the obtained occupancy information.

B60R 21/16

US Classification:

738659, 738653, 738664

Abstract:

A method and apparatus () for testing an occupant position sensing system () of a vehicle () includes a motor () having a stationary portion () and a movable portion (). A test object () is fixed relative to the movable portion () of the motor (). A motor position sensor () senses a position of the movable portion () of the motor () relative to the stationary portion () and for providing a motor position signal indicative thereof. Motor drive electronics () are responsive to the motor position signal for controlling the motor () for moving the test object (). A data recorder () is adapted to receive and record data from the occupant position sensing system () and is adapted to receive and record the motor position signal provided by the motor position sensor ().
