    Abstract: An auto cruise control method for a hybrid electric vehicle is provided. The auto cruise control method maximizes an effect of enhancing fuel efficiency and simultaneously satisfies enhancement in driveability and fuel efficiency due to the application of a pulse and glide (PnG) pattern obtained by considering the characteristics of the hybrid electric vehicle (HEV). The method includes receiving a target vehicle speed by a driver input to turn on an auto cruise mode and to turn on a pulse and glide (PnG) mode in a hybrid electric vehicle using an engine and a driving motor as vehicle driving sources. One PnG mode among a PnG coast mode, a PnG glide mode, and a PnG cruise control mode are selected from a map based on the target vehicle speed and driving control of the selected PnG mode is then performed.
