Shift apparatus and control method of shift apparatus

A shift apparatus that is connected to a shift mechanism of a vehicle, which is a transmission, having a plurality of shift ranges including a first range and a second range and that is configured to perform switching of the shift ranges, the shift apparatus comprising:

• an operation member rotatably attached to the vehicle;
• a sensor configured to detect a position of the operation member;
• a regulation mechanism which is an electromagnetic brake, an actuator, or a motor configured to regulate a rotation of the operation member;
• and
• a processor configured to function as:
• a shift control section configured to select the first range when the operation member moves to a first position, to select the second range when the operation member moves to a second position, and to allow the shift mechanism to execute switching to the selected shift range;
• an operation control section configured to allow the regulation mechanism to regulate the rotation of the operation member;
• and
• a shift state determination section configured to determine whether the shift mechanism is or is not in a shift restriction state,
• wherein
• when the operation member moves to the first position and moves from the first position to the second position within a predetermined time after the operation member moves to the first position, the shift control section is configured to select the second range when the shift state determination section determines that the shift mechanism is not in the shift restriction state, and the shift control section is configured to select the first range when the shift state determination section determines that the shift mechanism is in the shift restriction state, and to allow the operation control section to execute the regulation by the regulation mechanism,
• the shift mechanism includes an output shaft and a shift lock portion that includes an actuator and that is configured to lock the output shaft in the first range,
• the shift state determination section is configured to determine that the shift mechanism is in the shift restriction state when a hindrance occurs in releasing the lock of the shift lock portion, and
• the shift control section is configured to perform control to release the lock of the shift lock portion, and
• the shift state determination section is configured to determine that the shift mechanism is in the shift restriction state when the lock of the shift lock portion is not released within a set time after the shift control section performs control to release the lock.
