Abstract
A method of improving fuel efficiency by analyzing a driving pattern of a vehicle may include: calculating weighting factors according to a driving pattern of the vehicle at coordinates, which are the ratios of weightings accumulated at the coordinates to the sum of the weightings accumulated at all coordinates in an engine operation region; calculating a reference fuel consumption ratio Kand a reference NOx exhaust ratio Kusing the weighting factors; determining whether the reference NOx exhaust ratio Kexceeds a predetermined comparative value; and controlling an engine to improve fuel efficiency when the reference NOx exhaust ratio Kis equal to or less than the predetermined comparative value.
