Abstract: A method of controlling reverse driving of a hybrid vehicle is provided, in which a reverse gear train of a gear box of a transmission for reverse driving is omitted. When a gear stage enters a reverse stage or is changed from a drive stage to a reverse stage, an engine performs an electric energy charging function on a battery via a hybrid starter generator and a motor transmits driving power for reverse driving to travelling wheels. Accordingly, the battery is charged with electric energy and simultaneously, the motor is reversely driven based on the electric energy supplied from the battery, thereby enabling a hybrid vehicle to be more easily reversed.
