Innovative Chip Set for Pressure and Acceleration Based Airbag Solutions 2004-01-0846

More and more passenger cars are equipped with passive side protection systems such as thorax airbags for front and rear passengers. In the past, side airbag protection systems used sensors based on acceleration measurements [1]. In the meantime different sensor principles have been tested in order to increase the performance of this application. The intention has been to achieve faster firing decisions and to decrease the misuse risk for a floor or chassis impact. This paper presents the partitioning of an advanced chipset for pressure and acceleration based airbag systems. It shows the communication link between the sensors, the receiver-IC and other blocks in the application.
