An active grille shutter system for use in a moving vehicle, comprising:
- at least one vane angularly displaceable between an open position and a closed position;
- a motor having a hold current applied thereto for maintaining the at least one vane in a vane position;
- and
- a controller for adjusting the amount of hold current being applied to the motor based on vehicle speed.
An active grille shutter system for use in a moving vehicle, comprising:
- at least one vane;
- an actuator for maintaining the at least one vane in a vane position;
- and
- a controller configured to adjust an amount of power applied to the actuator based on a vehicle condition.
A method for maintaining at least one vane in a selected vane position while a vehicle is moving, comprising the steps of:
- sensing vehicle speed;
- applying power to an actuator to hold the at least one vane in the selected vane position;
- and
- adjusting the amount of power being applied to the actuator based on the sensed vehicle speed.
