Offset angle determination method for sensor angle signals, e.g. for use with automotive AMR or GMR sensors, whereby offsets are based on determination of a sine signal value at a maximum cosine signal value and vice versa

摘要

Method for determining the offset between sensor angle signals (X, Y) has the following steps: determination of a first angle position at which the sine signal reaches a maximum, determination of the corresponding cosine signal value, setting the cosine signal value as a cosine offset, determination of a first angle position at which the cosine signal reaches a maximum, determination of the corresponding sine signal value, setting the sine signal value as a sine offset.
