Der Einfluss von Störschwingungen, die vom Fahrzeug ausgehen und die sowohl die Qualität des elektrischen Sensorbaugruppensignals als auch die Belastung der Sensorbaugruppe als Bauteil zumindest mitbestimmen, wird üblicherweise lediglich bei der Auswahl des Einbauortes der Sensorbaugruppe am Fahrzeug berücksichtigt.Acceleration-dependent sensor modules, In particular sensor modules for detecting a necessary airbag deployment or for Recognition of a necessary vehicle dynamics control, are usually in a separate housing or over attached functionally associated control units on the vehicle. Of the Influence of disturbing vibrations, which emanate from the vehicle and which both the quality of the electric Sensor module signal as well as the load on the sensor assembly At least co-determine as a component is usually only at the selection of the installation location of the sensor assembly on the vehicle considered.
Es ist Aufgabe der Erfindung, die Genauigkeit und die Lebensdauer beschleunigungsabhängiger Sensorbaugruppen zu erhöhen.It Object of the invention, the accuracy and the life of acceleration-dependent sensor modules to increase.

The Objects of dependent claims are advantageous developments of the invention.
Die Erfindung ist eine Befestigungsvorrichtung für eine beschleunigungsabhängige Sensorbaugruppe in Kraftfahrzeugen, die zumindest indirekt über eine Trägereinheit mit dem Fahrzeug, insbesondere einem Karosserieteil, verbunden ist. Dabei ist ein zusätzlicher Störanteilsensor am Einbauort der Sensorbaugruppe mit dem Fahrzeug verbunden. Der zusätzliche Störanteilsensor erfasst Störschwingungen und leitet diese an eine Steuereinheit weiter. Die Steuereinheit prägt über einen Aktuator definierte Störschwingungen kompensierende Schwingungen auf die beschleunigungsabhängige Sensorbaugruppe ein. Dabei ist in einer ersten Alternative der Aktuator mit der Trägereinheit zumindest teilweise verbunden. In einer zweiten Alternativer bildet der Aktuator selbst die Trägereinheit.The The invention is a fastening device for an acceleration-dependent sensor assembly in motor vehicles, at least indirectly via a carrier unit with the vehicle, in particular a body part, is connected. There is one additional Störanteilsensor connected to the vehicle at the installation site of the sensor assembly. The additional Störanteilsensor detects disturbing vibrations and forwards them to a control unit. The control unit coins about one Actuator defined disturbing vibrations compensating vibrations on the acceleration-dependent sensor module one. Here, in a first alternative, the actuator with the support unit at least partially connected. In a second alternative forms the actuator itself, the carrier unit.
Die definierten zu kompensierenden Störschwingungen können alle auftretenden bzw. messbaren Störschwingungen oder auch eine Auswahl der auftretenden bzw. messbaren Störschwingungen sein.The defined to be compensated spurious vibrations can all occurring or measurable disturbing vibrations or also a selection of occurring or measurable disturbing vibrations.
Durch die Erfindung wird eine aktive Schwingungsdämpfung erzielt, die vorzugsweise nicht alle, sondern nur bestimmte definierte Störschwingungen, insbesondere bei bauteilbezogenen Resonanzfrequenzen, erfasst.By the invention achieves an active vibration damping, preferably not all, but only certain defined spurious, in particular at component related resonant frequencies detected.
Vorzugsweise ist die als Aktuator ausgestaltete Trägereinheit ein Piezoelement.Preferably is designed as an actuator carrier unit is a piezoelectric element.
Die erfindungsgemäße Befestigungsvorrichtung wird insbesondere bei beschleunigungsabhängigen Sensorbaugruppen bzw. bei Steuergeräten mit beschleunigungsabhängigen Sensorbaugruppen in einer Gewichtsklasse von unter 500 Gramm verwendet.The inventive fastening device is particularly important for acceleration-dependent sensor modules or with control units with acceleration-dependent Sensor assemblies used in a weight class of less than 500 grams.
Weiterhin wird die erfindungsgemäße Befestigungsvorrichtung bevorzugt zur Kompensation von Störschwingungen im Frequenzbereich von etwa 30 Hz bis 1500 Hz verwendet.Farther is the fastening device according to the invention preferred for compensation of spurious oscillations in the frequency domain used from about 30 Hz to 1500 Hz.
