Abstract
An electronic transmission range selection (ETRS) system for a motor vehicle transmission includes an ETRS housing disposed on the transmission, the ETRS housing having a magnetic field sensor in communication with a transmission controller; and a magnetic field source including a magnet component and a high magnetic permeability component. The magnetic field source disposed on a transmission selector shaft, the magnetic field source detectable by the magnetic field sensor at a plurality of predetermined positions along a movement path of the transmission selector shaft; and the magnetic field sensor detecting magnetic flux generated by the magnetic field source, and communicating magnetic field source position information to the controller. The high magnetic permeability component homogenizes the magnetic flux generated by the magnet component and the controller generates an electronic transmission mode signal based on the magnetic field source position information.
