Apparatus and method for testing and occupant position sensing system of a vehicle

摘要

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 ).
