  • Occupant based frequency analysis algorithm
    Patent number: 6697723
    Abstract: An occupant classification system (12) for an automotive vehicle (14) is provided. The system (12) includes a weight-sensing device (24) that generates a weight signal and an accelerometer (26) that generates an acceleration signal. The weight-sensing device (24) and the accelerometer (26) are coupled to a seat system (20). A controller (22) is electrically coupled to the weight-sensing device (24) and the accelerometer (26). The controller (22) determines occupant classification in response to the weight signal and the acceleration signal by monitoring a frequency domain representation of the weight signal divided by the acceleration signal. A method for performing the same is also provided.
