Abstract

Die Erfindung betrifft einen Sensor und/oder ein Sensorsystem (Auslösesensor), insbesondere geeignet für ein Insassenschutzsystem/Unfallschutzsystem, mittels diesem beispielsweise mit wenigen Auslösesensoren eine einfache sowie präzise Sensierung und Erkennung von unterschiedlichen Crasharten/Fahrsituationen/dynamischen Abläufen ermöglicht wird, wobei insbesondere bereits der Sensor mindestens zwei unterschiedliche Frequenzbereiche am Ausgang zur Verfügung stellen kann, damit ein aufwendiges Herausfiltern der erforderlichen Frequenzen, mittels spezieller Filtereinrichtungen am Ausgang des Sensors des Sensors, aus dem sonst üblichen Beschleunigungssignal entfällt.
