Purely electric vehicles are today almost exclusively equipped with a single speed transmission. However, hybrid powertrains are equipped with automatic transmissions. The integration of at least one electric machine increases the complexity of the transmission architecture and the functional software.
The development of dedicated hybrid transmissions seeks to reduce transmission complexity by taking over functions previously provided by the transmission from the e-machines. This opens up many possibilities for novel powertrain systems. At the same time, new challenges arise in the design, integration and control of such systems. The IMS does research in the field of powertrain and transmission technology in order to meet the current challenges and thus to exploit the full potential of innovative systems. The focus is on the optimal design and control of the powertrain. The target criteria that are optimized are efficiency, driving performance, driving and shifting comfort as well as costs. Some completed and ongoing projects deal with different variants of the Two-Drive-Transmission. This innovative powertrain concept of the IMS provides a platform for exploring the diverse possibilities of dedicated, electrified transmission systems.
