Abstract
A shift range control apparatus controls switching of a shift range by controlling driving of a motor, and includes a signal acquisition unit and a drive control unit. The signal acquisition unit acquires rotation angle signals output from a rotation angle sensor. The rotation angle signals respectively represents three or more phases different from each other. The drive control unit controls the driving of the motor to cause a rotational position of the motor to reach a target rotational position corresponding to a target shift range. The drive control unit changes from an energization pattern in a normal state to an energization pattern and continues the driving of the motor, in response to detecting a fault of the rotation angle signal during the switching of the shift range.
