APPARATUS AND METHOD FOR PROVIDING DISTANCE TO EMPTY INFORMATION FOR A VEHICLE

A method provides information on a distance to empty (DTE) of a vehicle and an information providing apparatus performs the method. The method includes: determining average fuel efficiency based on a travel distance of a vehicle and the cumulative amount of electrical power consumption after start of one driving cycle by vehicle key-on; determining short fuel efficiency by averaging fuel efficiencies calculated at a predetermined travel distance interval after the start of one driving cycle; determining an average fuel efficiency application ratio corresponding to vehicle driving information after the start of one driving cycle using setting information; determining a guide DTE value reflecting the average fuel efficiency and the short fuel efficiency according to the average fuel efficiency application ratio; and controlling operation of a display device to display the guide DTE value.
