Abstract:
An occupant classification system () for an automotive vehicle () is provided. The system () includes a weight-sensing device () that generates a weight signal and an accelerometer () that generates an acceleration signal. The weight-sensing device () and the accelerometer () are coupled to a seat system (). A controller () is electrically coupled to the weight-sensing device () and the accelerometer (). The controller () 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.
