An arrangement for measuring an angular position of a rotor with respect to a stator, comprises a multi-pole magnet mounted on the rotor, and a sensor mounted on the stator and a plurality of sensor elements organized in two groups or four groups for measuring a magnetic field component. A method for calculating the angular position 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, and the use of such arrangement or sensor in an automotive environment. |
