Abstract
A method of controlling a hybrid electric vehicle is provided. The method includes determining whether a condition for turning off an engine is satisfied and determining engine clutch disengaging time and residual purge gas consuming time from engine driving status information when the condition is satisfied. Engine clutch-engaged charging control time is determined from the engine clutch disengaging time and the residual purge gas consuming time. The method includes closing a purge control solenoid valve and starting to perform engine clutch-engaged charging control. The engine clutch-engaged charging control is maintained for the determined engine clutch-engaged charging control time and then engine clutch disengaging control is performed for the determined engine clutch disengaging time. The engine is stopped after the engine clutch disengaging control is performed.
