Abstract
A method for learning an opening of an air control valve of a hybrid electric vehicle includes detecting data for controlling the opening of the air control valve during engine starting, detecting a change of a flap closing of the air control valve, controlling the opening of the air control valve to reduce a vibration based on the data when the engine is turned off, calculating the opening of the air control valve according to the flap closing of the air control valve, setting a reference value based on the change of the flap closing of the air control valve, comparing the calculated value with the reference value and when the calculated value is greater than the reference value, learning the opening of the air control valve as the calculated value after an ignition switch is turned off.
