Abstract:
The bi-dimensional position sensor (1) can be advantageously used in the turn system controlled from the steering wheel of a vehicle and comprises a permanent magnet (3) fixed to a control lever (4) so as to move in a plane along a first (X) and a second (Y) direction and rotate about a third direction (W) orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device comprising a first group of sensor elements (10 1 -10 3 ) arranged spaced along the first direction, a second group of sensor elements (10 4 -10 7 ) arranged spaced along the second direction and a third group of sensor elements (10 8 -10 9 ) detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet (3) may assume and a control signal (S) corresponding to the desired function.
