PROBLEM TO BE SOLVED: To provide a stable sensor output for a load applied via trim in an occupant discrimination system made by installing a sensor mat 6 under the seating surface of a seat 1. SOLUTION: After the assembly of the seat 1 is completed, a calibration process is carried out for this occupant discrimination system, Specifically, a big bag 15 with a fluid sealed therein is disposed on the seating surface of the seat 1 to press the seat 1 via the big bag 15. After a load impressed on the big bag 15 is removed, the sensitivity of each sensor cell is adjusted by an ECU 11, Variations in the sensitivity of the sensor cells cause variations in the output of the sensor cells even if a load is uniformly impressed via the trim on the sensor cells, Therefore, the sensitivity of the censor cells are individually adjusted according to the variations.
