Abstract
A shutter opening/closing control device is proposed which can reduce an operation noise of the shutter without increasing the manufacturing cost. The shutter opening/closing control device includes a grille shutter for opening and closing a grille opening which introduces the outside air into the engine compartment, a shutter opening and closing operating portion having a drive source for operating the shutter to be open or to be closed, a closing operation judging portion for judging whether or not the grille shutter is operated in a closing direction based on the vehicle information and a drive source torque controlling portion for controlling the drive source of the shutter opening and closing operating portion to operate the shutter by a low torque when the grille shutter is operated in a closing direction under the engine being stopped. The low torque is lower than a high torque by which the drive source operates the grille shutter in an opening direction.
