Occupant classification system for vehicle has controller which determines occupant classification based on weight and acceleration signal by monitoring frequency domain representing division of weight signal with acceleration signal

摘要

The occupant classification system (12) has a weight sensor (24) and an accelerometer (26) coupled to a vehicle seat system to respectively produce a weight signal and an acceleration signal. A controller (22) determines an occupant classification based on the weight signal and the acceleration signal by monitoring a frequency domain representing the division of the weight signal with the acceleration signal. Independent claims are also included for the following: (a) a collision countermeasure system; and (b) an occupant classification method.
