Abstract

In an evaluation process for output signals of an acceleration-sensitive sensor in restraint systems for vehicle occupants, the output signals of the sensor are picked up and evaluated periodically. In a normal, uncritical operating state the evaluation occurs after relatively long intervals of time. If indications suggest a critical operating state, that is, an accident, however the evaluation of the output signals of the sensor occurs at shorter intervals of time.
