Hybrid Vehicles in Physical and Virtual Environment

Scope of this research project is the optimization of diesel-hybrid powertrain configurations as well as operating strategy by implementing a newly developed methodology that allows investigating different passenger car hybrid powertrains with respect to their compliance with future RDE legislation. Herefore, the vehicle is interconnected with other traffic participants in a virtual environment.

For this research task the Center for Mobile Propulsion (CMP) of RWTH Aachen University provides optimal conditions for the introduction of such development methodology through its real-time capable system for testbench interconnection as well as the environment for close cooperation of research specialists.

Within this project, the new development methodology is implemented and demonstrated for two use cases:
In the scope of the first use case of individual mobility, the methodology is applied for a passenger car with diesel-hybrid powertrain. Herein, configuration and operating strategy of the hybrid powertrain are optimized with goal to achieve low emissions under real driving conditions (RDE).

Witin the second use case of logistics, focus is on distribution transport up to vehicle weights of 3.5 t. As for the first use case, different concepts of hybrid powertrains of light duty vehicles are simulated and evaluated using virtual scaling of components. The scope in the field of operational management is optimization of routes with respect to economic efficiency.

The Institute for Automotive Engineering (ika) of RWTH Aachen University is involved in the project with the contribution of an environment simulation, which generates information on the driving profile used as input for the powertrain test bench.
