Drive Systems

 

Modern drive systems make a major contribution to the performance, efficiency and, last but not least, the comfort of the vehicle. In this process, the increasingly complex interactions of the integrated subsystems, drive topology as well as the operation strategy play a decisive role. The focus of our research therefore is on methods for developing conventional, hybrid and electric drive systems in different fields of application and sizes. We are doing research on new types of simulation and test environments based on the IPEK-X-in-the-Loop-approach (IPEK-XiL-approach). This enables us to develop a system understanding of complex processes in the drive system.  We use this knowledge to develop innovative drive components and systems.
