Abstract:
An apparatus for use in combination with a transmission shift rail and adapted to measure the position of the shift rail having a longitudinal axis, which is contained within a transmission assembly, said apparatus comprising:a member secured to said shift rail the member including a first conical outer surface concentric with the axis, and a second cylindrical spiral outer surface disposed about the axis; a pair of sensors including a first sensor generating a first signal representing a distance between said first sensor the first surface as said shift rail rotates about the axis and a second sensor generating a second signal presenting a distance between said second sensor and the second surface as said shift rail moves along the axis; and a controller communicatively coupled to said pair of sensors, receiving said first and said second signals, and determining the position of said shift rail by use of said first and second signals.
