Abstract
An air-fuel ratio control method reflecting a brake booster inflow flow rate includes: determining a deviation between an actually measured pressure of an intake manifold and a model pressure of the intake manifold is equal to or greater than a predetermined value; determining that the deviation is caused by a brake operation; correcting an intake air amount by reflecting a flow rate flowing into the intake manifold from a brake booster; and performing an air-fuel ratio control based on the corrected intake air amount.
