Abstract:
A method for calibrating an offset of an angle sensor, which determines an angle on the basis of a sine signal assigned to the angle and a cosine signal assigned to the angle, said method having the following steps:a) determining the sine signal and the cosine signal for at least three different angles (1,2,3) to obtain at least three sine-cosine value pairs (U sin(1), U cos(1); U sin(2), U cos(2); U sin(3), U cos(3)), each containing one sine signal value and one cosine signal value; b) displaying the at least three value pairs in an at least two-dimensional coordinate system that represents a sine signal-cosine signal plane; and c) determining a point, representing the offset to be calibrated, in the coordinate system, in relation to which point the at least three value pairs are located on an arc.
