1.1 Funktion und Bedeutung<\/p>\n
Ein Lenkwinkelsensor ist ein Gerät, das den Drehwinkel des Lenkrads oder der Lenkwelle misst und in ein elektrisches Signal umwandelt. Dieses Signal wird verwendet, um Rückmeldung an verschiedene elektronische Systeme im Fahrzeug zu geben, wie beispielsweise die Elektronische Stabilitätskontrolle (ESC), fortschrittliche Fahrerassistenzsysteme (ADAS) und automatische Fahrfunktionen. Genauigkeit, Zuverlässigkeit und Haltbarkeit sind entscheidend, da ein defekter Sensor die Leistung dieser sicherheitskritischen Funktionen beeinträchtigen kann.<\/p>\n
