Filtering of a sensor signal, that is applied to a motor vehicle safety system, whereby a cut-off frequency is adjusted dependent on the sensor output signal curve

Device for filtering a sensor signal (10) comprises a filter (12) to which the sensor signal is applied, and which has a switchable cut-off frequency, and a control circuit (16, 18) that switches the filter cut-off frequency dependent on the sensor signal curve. An independent claim is made for a me...

Beschreibung
Zusammenfassung:	Device for filtering a sensor signal (10) comprises a filter (12) to which the sensor signal is applied, and which has a switchable cut-off frequency, and a control circuit (16, 18) that switches the filter cut-off frequency dependent on the sensor signal curve. An independent claim is made for a method for filtering a sensor signal. Die Erfindung betrifft eine Vorrichtung zum Filtern eines Sensorsignals (10) mit einem Filter (12), dem das Sensorsignal (10) zugeführt ist und das mindestens eine umschaltbare Grenzfrequenz aufweist, und DOLLAR A einer Regelschaltung (16, 18), die abhängig von einem Signalverlauf die Grenzfrequenz des Filters (12) umschaltet.
