    • 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.
    • 本发明提出了一种用于确定分离轴(3)中的旋转角(Phi)和/或角度差(delta)的方法,其具有设置在其上的多个相位轨迹(1a,1b,2a和2b) ,其中提供了代码。 通过评估单元,每组轨道(1a,1b,2a和2b)提供相对于轴(3)的旋转分别不明确的相位信号(α1,α2)。 至少两个相位信号(α1,α2)以加权方式相加以产生一个信号S,从该信号S计算整数部分和非整数部分。 非整数部分与两个磁道组之间的角度差(delta)成比例。 扭矩(M)通过与插入的扭矩杆的弹簧刚度相乘来确定。 借助于加权相加,从信号(S)的整数部分和相位值(α1)或(α2)确定明确转矩(Phi)。

    • The invention relates to a method for unambiguously determining a physical parameter Φ using m phase-measured values αi with 1≦i≦m, whereby the phase-measured values αi have different, integer periodicity values ni and an integer periodicity difference (a) with Δn>1 within an unambiguous range E of the physical parameter Φ. A value T with (b) and (c) is calculated based on the phase-measured values αi and the periodicity values ni thereof, and, within a reduced unambiguous range Ered with (d), a value V is allocated to the value T by allocation according to (e), wherein TUk stands for a respective lower limit and TOk for a respective upper limit of T. The allocation intervals between the upper (TOk) and the lower limits (TUk) for T, as wells as the distances (f) correspond at least to the periodicity difference Δn. In order to determine the physical parameter Φ, value V is added up with the C phase-measured values αi in a weighted manner.
