Claim:
A flap control apparatus of a vehicle comprising: upper and lower flaps disposed at a front side of the vehicle to adjust inflow of air into the vehicle; a drive unit opening and closing the upper flap; a locking unit locking the lower flap so as not to be opened by drive wind pressure; a movement detection sensor detecting movement of the upper flap resulting from an opening or closing behavior of the upper flap; an engine controller determining an operating condition of the upper and lower flaps; and a drive controller operating the drive unit and the locking unit in response to a drive condition signal from the engine controller and performing a fail-safe operation for the drive unit and the locking unit according to a detection value of the movement detection sensor and a communication state with the engine controller, wherein the drive controller opens the upper flap and releases the lower flap from a locked state when the communication state is not normal, and wherein the drive controller releases the lower flap from the locked state and outputs a fail signal to the engine controller when the movement of the upper flap is not detected.
