Modular Hybrid Powertrain

With the current and expected CO₂-emissions for passenger vehicles, a strong integration of hybridized powertrains will be necessary to reach these targets alongside other alternative propulsion systems, e.g. battery electric and fuel cell electric vehicles. The increasing diversity and complexity within a single fleet shows the challenges with current modular powertrain architectures, which are mostly derived from a manufacturing perspective and are not manufacturer independent. The answer to this problem can be observed today in different fields of application, e.g. the computer world with all its peripheral devices. The paradigm of functional design needs to be introduced in the development of the powertrain systems by utilizing object-oriented design methods. The goal of this project is to derive a modular powertrain architecture with an object-oriented layout. Dedicated use cases support the development of the interface design and the communication structure. The feasibility of this approach is shown with the simulation of driving scenarios in a virtual environment. The modularity is further demonstrated by introducing a novel object (electric heated catalyst) with the extension of the interaction between the objects and the resulting boundary conditions brought by the catalyst.
