Abstract

Featured are apparatuses and methods for economical driving of a hybrid vehicle. Such methods include determining a present fuel consumption efficiency control value by considering present fuel consumption as a real consumption amount of a fuel and a battery, determining a driving pattern fuel consumption efficiency control value by considering fuel consumption determined by a vehicle speed and a driving condition, and guiding economical driving to a driver by applying a weight value factor to the present fuel consumption efficiency control value and a driving pattern fuel consumption efficiency control value. Also featured is a hybrid vehicle embodying such apparatuses and methods.
