Impact detection

The Crash Safety Module (ACSM) detects all impacts throughout a 360° range.

Within the Crash Safety Module (ACSM), the direction and severity of the crash are determined based on inputs from the following external sensors:

• Airbag front sensor, left and airbag front sensor, right
• Airbag sensor, front door, left and airbag sensor, front door, right
• Left B-pillar airbag sensor and right B-pillar airbag sensor
• Longitudinal acceleration sensor and lateral acceleration sensor for impact detection in the Integrated Chassis Management (ICM)
• Vertical acceleration sensor in the Integrated Chassis Management (ICM)
• Yaw rate sensor in the Integrated Chassis Management (ICM)

The Crash Safety Module (ACSM) processes all acceleration data. An algorithm is used to calculate the direction and the severity of an accident based on this data.
