Approximately 20% of all fatal road crashes worldwide involve a vehicle rollover. The CAPS function Advanced Rollover Sensing utilizes not only data provided by the rollover sensor in the airbag control unit but also data from ESC. From the analysis of the vehicle's state, the airbag control unit recognizes critical driving situations even before a rollover begins. The function can thus provide a reliable triggering decision for seat-belt tensioners, side and head airbags or rollover bar even earlier than before, giving occupants the best possible protection.
