Patent ID: 7382107

Claim:
A shift range switching apparatus comprising: a detent mechanism provided in a shift range switching mechanism which establishes an actual shift range position corresponding to a rotation angle of a control rod, the detent mechanism mechanically holding the actual shift range position with an engaging structure using a spring force; an electrically driven actuator provided with an electric motor which drives an output shaft directly or via a reduction gear to rotate the control rod; and an electric motor control means for controlling the electric motor so as to switch the actual shift range position that the shift range switching mechanism establishes, wherein the electric motor control means includes a recognized position correcting means for correcting a rotation angle of a rotor that electric motor control means recognizes or a rotation angle of an output shaft that electric motor control means recognizes so as to correspond to the actual shift range position based on a first range in which a variation in output shaft angle is relatively small with respect to a variation in a rotor angle or a second range in which a variation in the rotor angle is relatively large with respect to a variation in the output shaft angle, and the electric motor is controlled based on an operation result of the recognized position correcting means.
