DUETT
Due to increasingly strict emission limits, more and more vehicles with alternative drive systems are entering the market. Hybrid drives with gasoline engines are now widespread. A hybridized diesel vehicle offers the possibility of further reducing CO2 emissions. In addition, the combination of an electric motor and a combustion engine enables the reduction of NOX emissions, since the diesel engine is not, or only very rarely, operated at unfavorable operating points. An efficient design of the complex powertrain requires a novel test bench infrastructure: With the help of the virtual shaft of the "Center for Mobile Propulsion" (CMP) the interaction of individual components can be studied. Digitally linked test benches enable to dimension and coordinate the individual elements of the drive train without having to create hardware compatibility between the components before a prototype is realized. Real-time capable models of the individual parts of the drivetrain are required within the scope of the ERDF project Duett (funding code EFRE-0800846) funded by the European Union, in order to not rely on hardware components at early project stages. The contribution of the IEM consists here in the creation of such a model of the electric traction machine in the drive train.
