METHOD AND APPARATUS FOR EFFICIENTLY COMPENSATING OFFSETS IN ANGLE SIGNALS OR PHASE SIGNALS

摘要

The invention relates to a method and an apparatus (40) for determining an angle f of angle sensors on the basis of a sine signal and a cosine signal which can both be associated with the angle. Said method encompasses the following steps: a first couple of values S0 comprising a first sine signal (y0) and a first cosine signal (x0) is acquired; a second couple of values S comprising a second sine signal (y) and a second cosine signal (x) is acquired; a third couple of values S' is formed from the difference between the second couple of values S and the first couple of values S0; and the angle f is determined from the third couple of values S', the offsets in the sine signals and cosine signals being compensated in said manner.
