ABSTRACT:
An inductive angle sensor for a motor vehicle has an oscillator circuit that generates a periodic AC oscillator-frequency signal in an exciting coil, at least one receiving coil, an evaluation circuit for detecting the signal induced in the at least one receiving coil, and a movable inductive coupling element that influences a strength of inductive coupling between the exciting coil and the at least one receiving coil. The oscillator circuit is a "soft" or "flexible" oscillator circuit such that when an interference frequency close to the oscillator frequency is coupled into the coil system, the oscillator circuit adapts the oscillator frequency and phase relationship to that of the interference frequency. Undesired overlapping effects are thus efficaciously prevented.
