4.2.3. Triggering time and triggering sequence

The Crash Safety Module uses the values transmitted by the sensors to determine the direction and severity of the crash.

In the case of a front-end crash, for example, correspondingly high acceleration values must be detected by the longitudinal acceleration sensor in the B-pillar and by the longitudinal acceleration sensor in the central sensor. Based on the acceleration forces, an algorithm detects the severity and direction of the crash. Using this information, the triggering times and the sequence of the restraint systems to be activated is calculated.

A possible imminent rollover is also detected and the appropriate protection systems are activated.
