Range switchover control system

A range switchover control system comprising:

• a motor provided as a drive power source;
• a range switchover mechanism that switches over a shift range among plural ranges by using drive power of the motor;
• a range selector that selects the shift range;
• and
• an electronic control unit programmed to switch over the shift range to a selected range by rotationally driving the motor to a target position set in accordance with the selected range,
• wherein the electronic control unit is programmed to update the target position, in a case that the selected range is changed from a pre-change range of the shift range to a post-change range of the shift range during rotational driving of the motor, from a pre-change target position corresponding to the pre-change range to a post-change target position corresponding to the post-change range when a direction of rotation of the motor toward the post-change target position is same as a direction toward the pre-change target position and a difference between the post-change target position and a present position of the motor is larger than a threshold value.
