ABSTRACT:
A device for triggering a passive safety system in a vehicle upon detection of an impact. At least two acceleration sensors, the sensitivity axes of which are aligned for detecting an angle of a frontal impact, are each assigned to a signal channel which, in series with the respective impact sensor, comprises an evaluation circuit, particularly an integrator circuit for its output signals, and a threshold value circuit. During the formation of the speed integral, the physical signal course and the course of the signal edges is evaluated by several logic units in a logical unit (LOG) in order to obtain factors which influence the integration constant of integrators (by multiplication and reduction) to enlarge the area that can be evaluated.
