Abstract:
1. A system for identifying a position of a gear shift lever, comprising: a magnetic field sensor comprising two or more magnetic field sensing elements, the two or more magnetic field sensing elements configured to generate two or more magnetic field signals in response to a sensed magnetic field influenced by a relative position between the magnetic field sensor and a target, the target comprising a ferromagnetic target, the target disposed proximate to the magnetic field sensor, wherein at least one of the magnetic field sensor or the target is configured to couple to the gear shift lever, the gear shift lever configured to move to select from among a plurality of gears, wherein the other one of the magnetic field sensor or the target is configured to couple to a structure stationary with respect to the gear shift lever, wherein the target comprises: an electronic circuit coupled to receive the two or more magnetic field signals, wherein positions of the two or more magnetic field sensing elements within the magnetic field sensor are selected as predetermined positions to result in the electronic circuit being operable to generate an output signal indicative of selected ones of the plurality of gears selected by the gear shift lever; and a back-biasing magnet, the two or more magnetic field sensing elements disposed between the back-biasing magnet and the target, the back-biasing magnet for generating the sensed magnetic field.
