Abstract (en)
[origin: WO2016024001A1] The invention relates to a method for determining a corrected rotation angle (x_t1) of a raw rotation angle (x) recorded using an angle sensor which, on the basis of the raw rotation angle (x), outputs first and second raw rotation angle signals (s_r, c_r) which have a periodic profile and are in an orthogonal relationship with one another, wherein a deviation from the orthogonal relationship between the sensor signals can occur on account of the error (y), having the steps of: determining a correction value (y) by means of a determination unit for determining the correction value (y) and making the correction value (y) available to a correction unit, applying the correction value to at least one of the raw rotation angle signals (s_r, c_r) by means of the correction unit for determining at least one corrected rotation angle signal (s_oc, c_oc), and calculating the corrected rotation angle (x_t1) using at least one of the corrected rotation angle signals (s_oc, c_oc).
