Title: METHOD FOR DETERMINING AN ANGULAR ERROR BETWEEN A ROTATIONAL ANGLE VALUE ASCERTAINED BY MEANS OF AN ANGLE MEASURING SYSTEM AND A REFERENCE VALUE
Abstract:
The invention relates to an angle measuring system (100) and to a method for determining an angular error between a rotational angle value ascertained by means of an angle measuring system (100) and a reference value. The rotational angle value is ascertained from a rotational angle signal of a rotational angle sensor (110) in an analysis unit (120) of the angle measuring system (100), which has the rotational angle sensor (110) and the analysis unit (120). The reference value is ascertained from a reference angle signal in the analysis unit (120) of the angle measuring system (100), and the angular error between the rotational angle value and the reference value is determined in the analysis unit (120) of the angle measuring system (100).
