    Abstract: Der hier vorgestellte Ansatz schafft eine Wischgestenerkennungsvorrichtung (160) zur Ermittlung einer auf ein bewegliches Oberflächenelement (140) einer Fahrzeugkomponente ausgeübten Wischgeste. Die Wischgestenerkennungsvorrichtung (160) umfasst eine Feder (250), die eine Vorspannung zwischen dem beweglichen Oberflächenelement (140) und einem Gehäuseelement (245) der Fahrzeugkomponente (130) ausübt. Ferner umfasst die Wischgestenerkennungsvorrichtung (160) einen berührungslos messenden Abstandsensor (224) mit zumindest drei an unterschiedlichen Positionen angeordneten Sensorelemente (222) zur Erfassung je eines Abstands (d) zwischen dem Oberflächenelement (140) und dem Gehäuseelement (245) an den Positionen der Sensorelemente (222). Schließlich umfasst die Wischgestenerkennungsvorrichtung (160) eine Auswerteeinheit (215), die ausgebildet ist, um die auf das Oberflächenelement (140) ausgeübte Wischgeste unter Verwendung eines Parameters der Feder (250) und den von den Sensorelementen (222) erfassten Abständen (d) zwischen dem Oberflächenelement (140) und dem Gehäuseelement (245) zu ermitteln.
