Abstract

See full text

A method operates a hybrid drive operable selectively in a first operating mode powered by only an internal combustion engine or in a second operating mode powered by only an electric motor. Prior to starting a trip, for which a route that leads from a start to a destination is determined, the entire route to be traveled is segmented, according to pre-defined logic, into a plurality of route sections. These route sections are used to select certain route sections that are ever taken into consideration, based on certain route section criteria, for driving in the second mode. From, the selected certain route sections, those are used to identify and to drive on the route in the second mode in which route travel in the second mode yields a total maximum fuel economy advantage compared to driving the route in the first or any other mode.
