Abstract:
A process for the direction-selective triggering of a passive safety device in a vehicle, particularly relevant to an airbag system,where at least two acceleration transducers and one evaluation device are provided, to pick up the signals coming from the acceleration transducers, processes them and if the vehicle is involved in a crash, make output signals available to trigger the passive safety device, andthe acceleration transducers have directional sensitive axes, where the sensitive axes have actual instantaneous orientations and are aligned in different and preferably specified reference orientations and there is an angle tolerance between the reference and instantaneous orientations of the sensitive axes wherein,there is angle correction, by converting the n signals (am 1, am 2, . . . am n) coming from n.gtoreq.2 acceleration transducers to n output signals (a(I), a(II), . . . a(n)), where the output signals (a(I), a(II), . . . a(n)) are linear combinations of incoming signals (am 1, am 2, . . . am n) with adjustable factors (c.sub.ij): ##EQU6##
