Abstract (en)
[origin: WO2014095652A1] The invention relates to a method for detecting a phase angle difference (74) between a first periodic measurement signal (50) and a second periodic measurement signal (54), wherein, for the purpose of determining a torque (28) applied to a shaft (6), the two periodic measurement signals (70, 72) describe a rotation of the shaft (6) at an axial distance from one another, comprising: superimposing a periodic auxiliary signal (62) which simulates a previously known rotational speed for the shaft (6) on the first periodic measurement signal (50) in order to form a superimposition signal (70), and determining the phase angle difference (74) on the basis of the superimposition signal (70) and the second measurement signal (54).
