Airbags have improved the performance of adults occupant safety. However children who sit in front passenger seats have got fatal injuries. Due to this risk of airbags to children, National Highway Transportation and Safety Administration has made vehicles equipped with Automatic Suppression Systems. These systems detect the passenger status such as adults, children and CRS. Using this information of passenger status, Sensing & Diagnosis Module makes decision whether passenger front airbag is suppressed or deployed. In this paper, Performance and qualities of two types of passenger sensing systems were compared. One uses pattern recognition system and the other uses weight recognition system. Pattern recognition system uses pressure distribution pattern of occupant and weight recognition system uses weight of occupant to classify the occupants. In this research, Sensors of pattern recognition system were located on top of cushion but sensors of weight recognition system were behind cushion foam. In order to measure the performance, correct decision ratio of 5th%ile was used and quality index was used for defining the qualities. The results showed that average correct decision ratio of pattern recognition system and weight base system were 98.84% and 98.52% respectively. Both systems had good performance but positions of 5th%ile which have incorrect decision were different. In order to compare the quality, quality index was used. Quality index was measured by the incidents ratio from fields. When this index of pattern recognition system is 100%, the index of weight recognition system was 40%. Both systems had good enough qualities but weight recognition system was better because it seemed that sensor location of weight recognition system is under cushion of seats.
