Abstract:
A system and an associated method provide an ability to sense, with a magnetic field sensor, a position of a plurality of gears (and neutral) selected by a gear shift lever of a vehicle. In some embodiments, the system and method use a ferromagnetic target having features, positions of which can be sensed by the magnetic field sensor. In other embodiments, the system and method use a magnet having features and characteristics that can be sensed by the magnetic field sensor.
