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.
