Abstract
A shift range control apparatus switches a shift range by controlling a motor and is applied to a vehicle shift-by-wire system. The shift range control apparatus is configured to: switch an energization phase of a motor for one step of a predetermined energization pattern to one rotation direction or a different rotation direction of the motor in a control for learning a play decrease angle; determine whether a detection value of the output shaft sensor has changed; and learn, as the play decrease angle, an angle of the motor shaft when it is determined that the detection value of the output shaft sensor has changed.
