The electrification of vehicle drives is increasing the variety of possible vehicle drivetrains. This is due to the fact that the integration of electric machines into the drivetrain enables new transmission concepts and therefore the connected combustion engine can also be operated in different ways. In addition, a specific drivetrain configuration can only ever be designed optimally in terms of defined requirements. As the requirements differ depending on the market, customer or vehicle segment, the systematic development of requirement-optimized powertrain concepts is required.
The aim of the project presented is to create a synthesis program that systematically develops a drive concept for a given vehicle that is optimized to meet the requirements. Both the user input and the legal requirements are taken into account in order to achieve optimum values in terms of performance and efficiency. A computer-aided synthesis of topologies, units or components of a powertrain also makes it possible to examine all theoretically conceivable combinations of the unit-specific design parameters under consideration and to identify promising concepts by applying suitable evaluation criteria. By generating all theoretically conceivable parameter combinations, new variants of topologies, units or components can also be identified by means of synthesis.
