Abstract:
A method for adaptively calibrating a position sensor (46) for sensing a position of a shift member movable in an H-type shift pattern in an X-X direction for selection of gear ratios to be engaged and disengaged, and in a Y-Y direction from and toward a centered neutral position for engaging and disengaging selected gear ratios, said position sensor providing a first signal (SL.sub.X-X) having a magnitude indicative of a sensed X-X position of said shift member in said shift pattern and a second signal (SL.sub.Y-Y) having a magnitude indicative of a sensed Y-Y position of said shift member in said shift pattern, said method comprising the steps of:sensing current values of said first and second signals;determining a value indicative of a change in said first signal;comparing said value indicative of a change in said first signal to a reference value;if said value indicative of a change in said first signal exceeds said reference value, determining a neutral value (N.sub.Y-Y) indicative of a neutral position of said shift member in said Y-Y direction as a function of said current value of said second signal.
