摘要： The invention proposes a method for determining a rotation angle or distance by evaluating a multitude of phase measurement values. By means of a linear transformation A, the phase values measured in an N-dimensional space are projected into N-1 new signals Si. These signals Si are transformed by a quantizing device into corresponding integer values Wi and converted into N real values Zi by means of a linear projection C. These values have weighted phase measurement values &agr;i added to them in modulo 2&pgr; fashion, which yields N estimates for the angle &phgr; to be measured. The N estimates are corrected if needed at their skip points and are added up in a weighted fashion, taking into account their phase angle.

摘要： The invention proposes a method for determining a rotation angle (&PHgr;) and/or an angular difference (&dgr;) in a divided shaft (3), which has a number of phase tracks (1a, 1b, 2a, and 2b) disposed on it, which are provided with codes. Via an evaluation unit, each group of tracks (1a, 1b, 2a, and 2b) supplies a phase signal (&agr;1, &agr;2), which is respectively ambiguous with regard to a rotation of the shaft (3). The at least two phase signals (&agr;1, &agr;2) are added up in a weighted fashion to produce a signal S from which the integer portion and the non-integer portion are calculated. The non-integer portion is proportional to the angular difference (&dgr;) between the two track groups. The torque (M) is determined through multiplication with the spring rate of an interposed torque rod. The unambiguous torque (&PHgr;) is determined from the integer portion of the signal (S) and a phase value (&agr;1) or (&agr;2) with the aid of a weighted addition.

摘要： In a method for ascertaining a rotational direction of a rotating body, one rotational direction and one rotational speed value which indicates the rotational frequency of the rotating body are ascertained in each of multiple measurements. The rotational speed values of the multiple measurements are compared to each other, and a rotational direction of the rotating body is ascertained from the measured rotational directions and the comparison of the rotational speed values.
