Erschütterungserfassungsvorrichtung zum Ermitteln einer Erschütterung bzw. eines Einschlags auf ein Batteriepack eines Fahrzeugs

Resumen de: DE102024211078A1

Die vorliegende Erfindung betrifft eine Erschütterungserfassungsvorrichtung (12) für ein Batteriepack (10) für ein Fahrzeug. Die erfindungsgemäße Erschütterungserfassungsvorrichtung weist zumindest einen am Batteriepack (10) des Fahrzeugs angeordneten Sensor (14), beispielsweise Klopfsensor, und zumindest einen am Batteriepack (10) angeordneten Resonator (20a, 20b, 20c), beispielsweise eine Stimmgabel, auf. Dabei erzeugt der zumindest eine Resonator (20a, 20b, 20c) ein Signal (24A, 24B, 24C), wenn das Batteriepack (10) einen Einschlag erfährt. Das Signal (24A, 24B, 24C) wird dann an den zumindest einen Sensor (14) übertragen. Wenn das Batteriepack (10) während dem Betrieb eine Erschütterung oder einen Einschlag erfährt, schwingt jeder Resonator (20a, 20b, 20c) bei einer spezifischen Frequenz und der zumindest eine Sensor (14) erfasst diese Frequenzen zusätzlich zum ursprünglichen Einschlag. Der zumindest eine Sensor (14) sendet dann die Frequenzspektren an eine elektronische Steuerungsvorrichtung (ECU) des Fahrzeugs, die die Amplitude der verschiedenen Frequenzen bestimmt und die Intensität und Position des Einschlags unter Verwendung von Triangulation berechnet.
