Abstract

So that an arrangement may decide to trigger a safety device in as error-free and reliable a manner as possible, provision is made for a first arrangement, which derives a first decision criterion for triggering a safety device from the measured turning rate at least about the longitudinal axis of the vehicle and/or from the measured accelerations at least in the direction of the transverse axis and the vertical axis of the vehicle. In addition, a second arrangement is present, which, independent of the first arrangement, derives a second decision criterion. A circuit arrangement then generates a triggering signal for the safety device, when both decision criteria are satisfied at the same time.
