Abstract:
A method of preserving calibration data for use by a seat occupant detection system in a vehicle, the method comprising the steps:providing dedicated memory locations for vehicle identification data and seat calibration data in a first rewritable, non-volatile memory within an occupant detection system module in the seat occupant detection system and a second rewritable, non-volatile memory external to the occupant detection system; obtaining vehicle identification data from the vehicle; determining if the vehicle identification data obtained from the vehicle matches vehicle identification data stored in the first rewritable, non-volatile memory; and if the vehicle identification data obtained from the vehicle matches the vehicle identification data stored in the first rewritable, non-volatile memory, copying seat calibration data stored in the first rewritable, non-volatile memory to the second rewritable, non-volatile memory.
