Apparatus and method for controlling active air flap

An apparatus for controlling an active air flap (AAF) of a vehicle, the apparatus comprising:

• a plurality of sensors configured to detect status information of the vehicle;
• an opening degree controller configured to control an opening degree of the AAF;
• and
• a processor configured to:
• determine a target flow and a target opening degree of the AAF based on the status information;
• calculate an initial speed of a wake generated by a preceding vehicle of the vehicle based on vehicle information of the preceding vehicle;
• obtain a speed of the wake at a time when the wake arrives the vehicle based on a speed of the vehicle, an inter-vehicle distance between the vehicle and the preceding vehicle, and the initial speed of the wake;
• correct the target opening degree based on the speed of the wake at the time when the wake arrives the vehicle;
• and
• control the opening degree control apparatus to adjust the opening degree of the AAF corresponding to the corrected target opening degree.
