Abstract:
A shift range control device includes an angle calculation unit, a target angle setting unit, a learning unit and a drive control unit. The learning unit learns a correction value to be used in calculating a motor angle target value based on a motor angle and an output shaft signal. The learning unit learns the correction value based on at least a first change point value, which is the motor angle at a timing at which the output shaft signal changes when a rotation member rotates in a first direction from a state in which an engagement member is in the center of valley section, and/or a second change point value, which is the motor angle at a timing at which the output shaft signal changes when the rotation member rotates in a second direction from a state in which the engagement member is in the center of the valley section.
