Occupant classification system

摘要

A collision countermeasure system 10 and an occupant classification system 12 for an automotive vehicle 14. The occupant classification system 12 includes a weight-sensing device 24 that generates a weight signal and an accelerometer 26 that generates an acceleration signal both of which are coupled to a seat system 20. A controller 22 is electrically coupled to the weight-sensing device 24 and the accelerometer 26 and is operable to determine an 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.
