Electronic Crash Sensing Unit for Airbag

This paper describes an electronic crash sensing unit which uses a semiconductive accelerometer for implementing a single point sensing system. This electronic sensing unit uses a new crash recognition mechanism utilizing two-dimensional discrimination function.

A new crash recognition mechanism is capable of providing reliable crash recognition in high speed crashes, as well as reliable performance in non-deployment situations.

This paper also discusses the evaluation procedures which compare recognition processing time and the robustness of the scheme.
