Abstract
A purge control method of the present disclosure includes determining whether or not a vehicle quickly decelerates in a driving situation in which a large amount of fuel evaporation gas is discharged, decreasing purge duty for operating a purge control solenoid valve when the controller determines that the vehicle is in a state of quick deceleration, and decreasing a purge flow of the fuel evaporation gas by controlling operation of the purge control solenoid valve by the purge duty.
