When developing an airbag system with mechanical sensors, one of the important stages is to get satisfactory correlation between the sensor characteristics and the specific vehicle. This development stage requires control of both vehicle crashworthiness (including selection of sensor mount location) and airbag sensor characteristics. This stage is ordinarily performed through many iterations of a computer simulation which involves the dynamic structure of the sensor mechanism.
A new graphic method is proposed in this paper to help in this simulation stage. This method can estimate the proper threshold level of the crash sensor. The airbag sensor mount location in the vehicle can be selected and the airbag sensor can be developed. The validity of the method has been verified by computer simulation as well as actual test results. The graphic method combined with a computer simulation seems more useful to the sensor tuning process, especially when the method simplifies the estimation of sensor location.
