Due to the great complexity of modern hybrid powertrains with the possibility of various component combinations and operation strategies, the overall system optimisation becomes even more complicated. In the FVV research project “Optimised layout of gasoline engines for hybrid powertrains under real world driving conditions”, the optimisation approach from the former project, involving a combination of statistical experimental design, longitudinal dynamics simulation and numerical optimisation was used [1]. The optimisation approach has now been extended at the Institute for Combustion Engines Aachen (VKA) for a broader application under realistic driving conditions.

1 Project Approach

The optimisation of the hybrid powertrains were done in four steps. In the first step, vehicle simulation models were created which allow a variation of the powertrain components and the operating strategy. In the second step a design of experiment test plan for the combination of all variable parameters...



This professional article is the scientific result of a research project assigned by Forschungsvereinigung Verbrennungskraftmaschinen e. V. (FVV, Frankfurt/Main) and conducted at the Institute for Combustion Engines of Aachen University of Technology (RWTH Aachen) under the supervision of Prof. Stefan Pischinger. The project was supported by a working group of FVV under the supervision of Dipl.-Ing. Martin Klenk, Robert Bosch GmbH. The authors thank the working group and especially Mr. Klenk for their considerable help.
