Abstract: A method for evaluating a sensor signal provided by a magnetic field sensor which is arranged at a distance from an object which is rotatable about an axis of rotation is disclosed. The method includes defining an encoding pattern with a sequence of symbols, the sensor signal being dependent on the encoding pattern and at least one transmission parameter; regenerating the symbols of the encoding pattern from a corrected sensor signal using a threshold value detector to obtain an output signal; generating a filtered signal from the output signal using a filter having a plurality of filter coefficients; superposing the sensor signal and the filtered signal to obtain the corrected sensor signal; and wherein the corrected sensor signal and the output signal are used to estimate the at least one transmission parameter, and the filter coefficients are derived from the estimated transmission parameter.

Abstract: A method for adjusting a determination rule for an error compensation of an angle sensor is designed to detect a first component of a direction along a first axis and a second component of a direction along a second axis, and to determine an angle of the direction according to the determination rule based on the first and second components. The method includes: detecting values of component pairs consisting of two predetermined components for the calculation of offset and/or amplitude and/or axis-angle errors. One variant consists of entering the component value pairs into an ellipse equation system, determining at least one ellipse coefficient from the ellipse equation system, and adjusting the determination rule depending on the one determined ellipse coefficient or the plurality of determined ellipse coefficients. A further variant is the determination of selected points, extremums or zero points for the determination of the offset and/or amplitude and/or axis-angle errors.
