Method and device for adjusting a determination rule of an angle sensor

摘要

A method for adjusting a determination rule for an error compensation of an angle sensor is designed to detect a first component of a direction along a first axis and a second component of a direction along a second axis, and to determine an angle of the direction according to the determination rule based on the first and second components. The method includes: detecting values of component pairs consisting of two predetermined components for the calculation of offset and/or amplitude and/or axis-angle errors. One variant consists of entering the component value pairs into an ellipse equation system, determining at least one ellipse coefficient from the ellipse equation system, and adjusting the determination rule depending on the one determined ellipse coefficient or the plurality of determined ellipse coefficients. A further variant is the determination of selected points, extremums or zero points for the determination of the offset and/or amplitude and/or axis-angle errors.
