Patent ID: 7370547

Claim:
A shift control system having a plurality of successive shift ranges and that switches a shift range among said plurality of successive shift ranges via an actuator, comprising: shift means driven by said actuator for switching the shift range; restriction means for restricting, in an endmost shift range among said plurality of successive shift ranges, rotation of said actuator in the direction where no adjacent shift range is present; rotation control means for rotating said actuator; count means for obtaining a count value according to a relative rotational amount of said actuator; and position setting means for setting, when said actuator is rotated by said rotation control means in the direction in which rotation of said actuator is restricted by said restriction means in said endmost shift range, a reference position of said actuator corresponding to said endmost shift range based on a state of said count value obtained by said count means, wherein said position setting means includes reference position setting means for setting the reference position of said actuator by detecting that said count value obtained by said count means is in a state where a minimum value or a maximum value of said count value is constant for a predetermined period of time.
