Arrangement (1) for measuring an angular position (alpha) of a rotor (2) with respect to a stator (3), the arrangement comprising a multi-pole magnet (5) mounted on the rotor (2), and a sensor (6) mounted on the stator (3) and a plurality of sensor elements (HH, VH) organized in two groups (S, T) or four groups (S, T, U, V) for measuring a magnetic field component (Br, Bt, Bz). Method for calculating the angular position (a) comprises making a sum of signals of the elements of each group, a ratio of the two sums, and an arctan function. Alternatively the method may comprise making a sum of signals, the difference of sums, a ratio of the differences, and an arctan function. An integrated sensor (6), and the use of such arrangement (1) or sensor (6) in an automotive environment. |
