By combination of an electric motor and an internal combustion engine in a hybrid powertrain significant reduction of fuel consumption is possible. In this thesis general considerations concerning the design of the electrical system for hybrid cars are presented and the concrete realization of the optimized CVT-Hybrid-Powertrain (continuously variable transmission), considered here, is described. A small dimensioning of the electrical drive is characteristic, which however does not negatively affect drivability, as an additional source of torque is utilized by dynamic gear ratio change of the continuously variable transmission. In doing so, powerful control and exact knowledge of characteristics of the CVT is essential, which are therefore examined by experiments in detail. The behavior is reproduced using a self-adjusting identification structure based on artificial neuronal networks.
