Abstract
The present invention provides a method for estimating a distance to empty (DTE) from the present amount of remaining fuel (the amount of remaining electricity) in an electric vehicle. In particular, the present invention provides a method for estimating a remaining travel distance of an electric vehicle, which can efficiently and accurately estimate a remaining travel distance by setting the relationship of a DTE with a state of charge (SOC) of a battery which changes in real time under various load conditions, in consideration of the present travel pattern, in addition to the SOC of a battery and accumulated fuel efficiency for the amount of remaining fuel of the electric vehicle.
