Claim 8:
9. A method of controlling switching of a shift range by driving an actuator and moving an engaging member in a drive system including an actuator having a drive source, and a detent mechanism having a plurality of valley portions and a peak portion separating the valley portions, and an engaging member movable between the valley portions when an output shaft is driven by the actuator, comprising
controlling a drive of the actuator;
determining, based on sensor information, that the engaging member passes over the peak portion when moving the engaging member to a target valley portion corresponding to a target range; and
estimating that the engaging member reaches a range of the target range corresponding to the target range at a peak passing over determination timing, which is the timing at which it is determined that the engaging member passes over the peak portion.
