摘要

Side airbags in the front and rear side doors are getting more and more standard in modern cars. Up to now mainly acceleration sensors are utilised to detect a side crash. In recent years a new concept for side crash detection has been used by some car manufacturers: The detection of the pressure pulse which is generated within the side door during the side crash. Compared to acceleration based systems the pressure detection method has some advantages. The firing decision can be made very fast and reliable. Furthermore the differentiation between misuse cases, i.e. non fire crashes, and fire crashes is very good. Infineon produces pressure sensor ICs for this application since 1998.
