Abstract (en)

[origin: WO2004051193A1] The invention relates to a method for reconstructing an angle signal (9) from a signal (7) of a sensor for angles of rotation. Said sensor comprises a periodic characteristic which encompasses several segments (S) and in which points of discontinuity (8) occur. In order to reconstruct the angle signal (9), positive and negative jumps (a-d) of the sensor signal (7) are determined and a segment number (SN) is generated if a positive or negative signal jump (a-d) is detected. An evaluation unit (4) is able to reconstruct the angle signal (9) based on the segment number (SN) and the sensor signal (7).
