Patent ID: 8296025

Claim:
A shift range switching control apparatus that instructs an actuator to switch to a target shift range of an automatic transmission mounted to a vehicle when an operation unit of a momentary type is operated in order to switch to the target shift range of the automatic transmission, the shift range switching control apparatus comprising: an operation judgment unit configured to judge whether or not the operation unit of the momentary type is operated from an original position thereof to a target position as an operation determination position which corresponds to the target shift range to be switched; and an incomplete operation detection unit configured to detect occurrence of an incomplete operation to the operation unit of the momentary type on the basis of a position detection signal transferred from a detection sensor, the detection sensor detecting a current position of the operation unit on the way from the original position to the operation determination position through an unstable position, the unstable position being between the original position to the operation determination position, and the detection sensor outputting the position detection signal, and the incomplete operation to the operation unit being a state in which the operation unit is automatically returned to the original position unless a detection of reaching the operation determination position corresponding to the target shift range to be switched after the operation unit is operated from the original position.
