Abstract
A method for compensating angular errors when determining angular values of an arrangement with a permanent magnet and at least two magnetic field sensors. A distance is formed between the permanent magnet and the magnetic field sensors in which a sine signal and a cosine signal are generated. An evaluation signal corresponding to the angular values is formed from the two signals using an arc tangent function, wherein arrangement errors and errors of a measurement and evaluation unit change the shape of the evaluation signal and lead to an angular deviation in the evaluation signal. To minimize the angular deviation, offset values of the signals are changed and offset values are ascertained by determining a first harmonic in the evaluation signal and/or a second harmonic in the signals and/or density differences of measurement points of a Lissajous curve.
