Abstract
A device and a method for triggering personal protection devices, characterized in that a roll rate sensor generates a roll rate while an acceleration sensor detects the transverse acceleration and the vertical acceleration. An integrator is provided to integrate the roll rate to yield an angle. The integrator starts integrating the roll rate when the roll rate exceeds a first threshold value and it stops the integration when the roll rate falls below a second threshold value. In addition, a threshold value controller is provided, adjusting the first and/or second threshold value according to the transverse and/or vertical acceleration. A processor triggers personal protection devices according to the angle and other criteria.
