Abstract

Es werden ein kapazitiver Drehsensor (1, 32), eine Auswerteschaltung (23) für einen Drehsensor (1, 32), ein Sensorsystem und eine Kfz-Verstelleinheit angegeben. Der kapazitive Drehsensor (1, 32) weist ein Drehelement (2) und ein diesem zugeordnetes Ruheelement (4) auf, wobei das Drehelement (2) und das Ruheelement (4) miteinander eine Kapazität ausbilden und wobei das Drehelement (2) zu einer Veränderung der Kapazität bei einer Drehung um seine Drehachse (5) ausgebildet ist. Zur Erhöhung der Zuverlässigkeit wird vorgeschlagen, dass das Drehelement (2) entlang der Drehachse (5) wenigstens zwei jeweils mit dem Ruheelement (4) eine Kapazität ausbildende Geberabschnitte (9, 10) aufweist.
