Sensoranordnung zur Positionserfassung von bewegbaren Teilen

摘要

The present invention relates to a sensor system (24) intended for locating moveable elements (20), preferably for retrieving a parking place by means of a windscreen wiper (12, 14). The sensor is used for making the edge of the voltage test signal (UM) steeper, thereby reducing the lack of accuracy when determining the location of the moveable element (20). The inventive system (24) includes a Hall sensor (30) and a control magnet (32) mobile relative to said captor and preferably so mounted on a rotating part (30) that, in case of relative motion by the mobile element (20) in the direction of movement, the control magnet (32) gets closer to the Hall sensor, aided by the attractive force first from the magnetic north pole (N) and then from the magnetic south pole.
