Vehicle Satellite Center (SFZ)

Vehicle Center Satellite (SFZ)

The SFZ is located on the transmission tunnel, under the front center console. The SFZ contains a transverse and longitudinal acceleration sensor.




The vehicle center satellite, center is not responsible for deploying any airbags or pyrotechnic devices.

The SFZ is connected to the SIM via the byteflight. The power supply of the satellite is also from the SIM and it is buffered by the memory backup capacitor. In sleep mode of the byfeflight, the power supply of the SFZ is deactivated by the SIM. The watchdog function is run via the SIM.

Sensor System




The vehicle center satellite only records sensor data; it has no triggering functions. One acceleration sensor for the longitudinal acceleration forces and one for the transversal acceleration forces are integrated in the SFZ.The sensors provide a variable voltage. This voltage is a measurement of the vehicle acceleration. This information is provided to the SIM and the other satellites for evaluation of crash thresholds.
