Abstract:
An apparatus for determining a first rotating angle of a first rotatable body, the first rotatable body cooperating with a second rotatable body and a third rotatable body, the apparatus comprising:a first arrangement measuring a second rotating angle of the second rotatable body;a second arrangement measuring a third rotating angle of the third rotatable body, wherein the second and third rotating angles are measured simultaneously; anda third arrangement determining the first rotating angle of the first rotatable body as a function of the second and third rotating angles, the third arrangement including a calculation device which determines the first rotating angle;wherein the first arrangement includes a first AMR sensor for measuring the second rotating angle, and the second arrangement includes a second AMR sensor for measuring the third rotating angle; andwherein the calculation device is capable of generating a start signal for triggering a simultaneous measurement of the second and third rotating angles by the first and second AMR sensors.
