Abstract
An electric grill shutter control device includes: a control portion that performs an energization of a motor that drives a movable member that configures the electric grill shutter; a detection portion that detects a rotational speed of the motor; a determination portion that determines whether locking of the movable member is occurred based on whether the energization is performed and the rotational speed; and an identification portion that obtains a rotation amount of the motor in a period around the locking from the rotational speed in a case where the locking occurs and identifying a cause of the locking according to the rotation amount and the energization.
