Abstract

A method and apparatus to save fuel and to make efficient use of the possibilities of a power train including a transmission having a continuously variable transmission ratio. If the vehicle velocity exceeds a prescribed velocity the fuel supply to the engine is shut off, kinetic energy of the vehicle is stored in an energy storage device, and the transmission ratio of the transmission is shifted in the direction of a lower transmission ratio. If those measures are not sufficient the vehicle brakes are operated.
