Abstract
A hybrid electric vehicle and method of controlling a drive mode therefore is disclosed. The method includes dividing a drive route into a plurality of intervals and operating a per-interval drive load for each of a plurality of the intervals, determining a reference drive load becoming a reference of change into a second drive mode from a first drive mode according to fluctuation of a charge state of a battery using the operated per-interval drive load, and setting an interval corresponding to the reference drive load among a plurality of the intervals as a first drive mode drive interval or a drive interval having the first drive mode and the second drive mode coexist therein. The setting is performed by considering a speed of the interval corresponding to the reference drive load and a speed of a next interval on the drive route.
