Abstract
A system and method for controlling an active grille shutter system for a vehicle upon startup of an associated engine includes determining if flaps of the AGS system are in a closed position upon cold-startup of the vehicle; moving the flaps to the closed position if it is determined that the flaps are not in the closed position upon cold-startup of the vehicle; and maintaining the flaps in the closed position until an engine coolant temperature (ECT) reaches a predetermined temperature that initially overshoots a predetermined continuous ECT target associated with steady-state operation of the engine. The initial overshoot of the ECT during cold-startup is configured to rapidly raise an engine oil temperature (EOT) to a predetermined continuous EOT target thereby reducing viscosity of the engine oil during cold-startup operation and increasing fuel efficiency of the vehicle.
