Abstract: The disclosure relates to a method for determining a corrected rotation angle of a raw rotation angle recorded using an angle sensor which, on the basis of the raw rotation angle, outputs first and second raw rotation angle signals which have a periodic profile and are in an orthogonal relationship with one another. A deviation from the orthogonal relationship between the sensor signals can occur based on the error. The method includes: determining a correction value by means of a determination unit for determining the correction value and making the correction value available to a correction unit, applying the correction value to at least one of the raw rotation angle signals by means of the correction unit for determining at least one corrected rotation angle signal, and calculating the corrected rotation angle using at least one of the corrected rotation angle signals.

Abstract: A method for determining an error between two sensor signals in an angle sensor which, based on an angle transmitter, outputs the sensor signals. The sensor signals have a periodic profile and are mathematically in an orthogonal relationship with one another. A deviation from the orthogonal relationship between the sensor signals can occur because of the error. The method includes forming a radius signal using the sums of squares of the sensor signals, and determining the second harmonic of the radius signal, where n is equal to a positive integer. The method also includes determining the error of a value of the amplitude at the second harmonic, which value has been phase-shifted through 90° with respect to the rotation angle value.
