Smart, green and integrated transport is one of the great social challenges of our time. The transport sector is currently the only sector where emissions are still rising. At the same time, the share of resources consumed by the mobility sector is so great that it alone can prevent reaching the climate goals. In our MobilityLab, we therefore investigate innovative vehicle and drivetrain concepts. User data and driving profiles ("big data") are increasingly included in the development. The goal is always directed towards increasing efficiency.
New multidisciplinary design approaches make it possible to consider the development and optimization of individual vehicle components, which usually take place separately in the classical simulation disciplines. The simultaneous consideration of several disciplines within an optimization loop - as a coupled simulation solution - can currently only be used very seldom due to high computation times or missing interfaces.
However, if different operating strategies for safe, effective or look ahead driving strategies are to be included, the detailed behavior of the components (mechanical, electrical, electronic, mechatronic, hydraulic, pneumatic and software-based) must be considered. For this purpose interfaces between the classical simulation disciplines have to be defined and appropriate submodeling techniques have to be developed.
The goals of the Mobility-Lab are therefore
- development of a methodical toolset (design tools, simulation and optimization methods and test stands) for innovative vehicle and drive concepts
- application and verification of the toolsets at demo station examples of the project partners
- sustainability analyzes and acceptance studies of new vehicle concepts
- simulation and optimization of mobility applications (aerodynamics, powertrains, electric motors, driving strategies)
