The present invention relates to a method for managing an internal combustion engine, a drive system of a hybrid vehicle provided with an electric machine having an energy storage means, the vehicle has information about the topology of the approaching road downlink interval. The method, wherein the step of predicting a vehicle power requirements in accordance with at least one gradient of the road section, the operating mode of the drive system even predicting, the operation mode of at least coasting downhill, the drive system by preferably downhill travel assisted only by the electric machine, to adjust the steps selected from the downhill traveling, which is braked by the energy recovery, the energy level in storage system before reaching the section of the road in accordance with the predicted and a step.
