Crash Detection and Determining Triggering (ignition) Point

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2008 MINI Cooper, 2007 MINI Cooper, 2006 MINI Cooper, 2005 MINI Cooper, and 2004 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.

The MRS 5 control unit determines whether a crash situation has occurred based on the values detected by the sensors and the triggering algorithm. The threshold values of two independent sensors must be detected in order to detect a crash. In the case of a frontal crash for example, the acceleration values from the B-pillar satellite and from the longitudinal acceleration sensor must be detected in the control unit.

The values serve the purpose of determining the crash severity and the crash direction. Based on the crash severity and direction, an algorithm determines the triggering (ignition) points of the restraint systems to be activated.
