Abstract: Pattern recognition was used to develop a complete intelligent control system for different feature
types of occupants used to reduce occupant damages in case airbags are mistakenly ignited in vehicle
collisions. The system uses image detection technology and integrates multiple external sensors to identify
occupant feature types. The airbag control system adjusts parameters, including the deflation-hole diameter,
the ignition time, the mass flow rate, and the strap length, to the optimal state according to five defined types
of occupants, including infants, children, the 5th percentile female, the 50th percentile adult male, and the 95th
percentile adult male to obtain protective effects for the different types of occupants in the vehicle collisions.
Test results show that the intelligent control system automatically and properly outputs signals for adjusting
parameters and ignition control while trailing to vehicle running environments.

Key words: airbags, visual inspection, occupant feature types, image pattern identification, intelligent control
