Detecting a Crash
The Crash Safety Module uses the values transmitted by the sensors to determine the direction and severity of the crash.
The threshold values of two independent sensors must be detected in order to detect a crash. In the case of a front-end crash, for example, the acceleration values from the B- B-Pillar satellite and from the longitudinal acceleration sensor must be detected in the Crash Safety Module.
Based on the crash severity and direction, an algorithm determines the triggering (firing) points and the order of the restraint systems to be activated.
