The implementation of advanced regulations for side impact crash tests require an improved and faster detection method for side impact crashes. Therefore the sensing principle must recognize the severeness of an accident with highest possible confidence and within shortest time. The use of pressure sensors inside a door cavity enables the system supplier to develop solutions to fulfill these requirements. Infineons 3
generation of pressure sensors for side crash detection offers a high flexibility to implement customer specific communication protocols. Furthermore, proven diagnosis functionality as well as additionally new features are integrated to guarantee a high reliability of the sensors for this special safety application. All active components for the entire pressure satellite could be integrated within the sensor.
