Abstract:
1. A shift control system switching a shift range by driving an actuator to rotate a detent plate according to a shift-range switch instruction, causing a detent spring to engage with said detent plate and thereby fix the shift range at a predetermined shift range, comprising: shift range switch means for a driver to input the shift range switch instruction; count means for obtaining a count value according to a rotational amount of said actuator; and position control means for rotating said detent plate into a predetermined target range based on said shift range switch instruction and said count value, said count means including means for obtaining said count value even in a period in which energization to said actuator is shut off, and said position control means including: means for resuming energization to said actuator if a rotational position of said detent plate is out of said target range in the period in which energization to said actuator is shut off; and means for rotating said detent plate into said target range after energization to said actuator is resumed.
