Abstract:
A process for triggering a passive safety device for vehicle occupants inside a vehicle where--by means of electric sensors that detect a critical vehicle condition, an evaluation circuit, and a triggering agent--an activation of these triggering agents is effected in relation to the acceleration signals generated by the sensors, wherein the following process steps are involved:a) quantification of the acceleration signals of a sensor by comparing the values of these acceleration signals with threshold values at the clock pulse of a specified first time pattern,b) detection of those acceleration signals whose associated quantified sensor signals simultaneously indicate an impact direction against the direction of vehicle travel,c) generation of a linearly increasing crash signal if in successive clock pulses the acceleration signals indicate an impact direction against the direction of vehicle travel,d) generation of a trigger threshold (K.sub.1 +R), increasing with the clock pulse of a second time pattern, at the point in time when the crash signal starts increasing linearly, ande) activation of trigger agents if the value of the crash signal reaches the trigger threshold (K.sub.1 +R).
