Airbag Triggering

Numerous crash and road tests under extreme conditions have been used to set the BMW triggering thresholds for all possible types of accidents.

The triggering thresholds are primarily divided into 4 groups according to crash severity:

• CS 0: no crash (parking damage) CS=Crash Severity
• CS 1: light crash
• CS 2: crash of medium severity
• CS 3: severe crash

The triggering thresholds have been set depending on the crash severity and including other factors such as direction, overlap on collision, and depending on the evaluation as to whether the occupant was wearing a seatbelt or not.

This results in the various trigger thresholds for the activation of the various restraint systems.
