In this paper the stepwise approach to a determination of an optimal hybrid powertrain configuration is explained. In a first step, a backwarded simulation with Dynamic Programming is used to determine a number of CO2-efficient topologies. In a further step, the level of detail of the simulation models is increased using a backwarded simulation with an ECMS approach. At a least step, the results of the first steps are verified using dynamic simulation models and a (MO-) ECMS. This ensures that the number of configurations to be calculated is constantly reduced over the detailing-stages. This procedure should make it possible to handle the variety of possible hybrid topologies in the design of a powertrain while keeping the computation level low.
