ANGLE METER WITH OFFSET COMPENSATION AND METHOD FOR COMPENSATION OF OFFSET OF AN ANGLEMETER

Method for compensation of the offset drift of an angle sensor that determines an angle based on a received sinusoidal or cosinusoidal signal. Method has the following steps: determination of the amplitude of the sinusoidal or cosinusoidal signal; determination of the corresponding offset value base...

Zusammenfassung:	Method for compensation of the offset drift of an angle sensor that determines an angle based on a received sinusoidal or cosinusoidal signal. Method has the following steps: determination of the amplitude of the sinusoidal or cosinusoidal signal; determination of the corresponding offset value based on the amplitude value; and determination of an angle measurement value taking into account the offset. An Independent claim is made for an angle sensor, especially an AMR (anisotropic magneto-resistive) angle sensor, with an evaluation unit for determination and application of an offset value.
