Claim 9:
10. An actuator control device 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 and that controls switching of a shift range by driving the actuator and moving the engaging member, comprising
a computer including a processor and a memory that stores instructions configured to, when executed by the processor, cause the processor to
control a drive of the actuator;
determine, 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
estimate 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.
