The aim of the cooperation project "Research for predictive diagnostics of electric machines in vehicle drives" is to research a scientific methodological basis for the early detection of fault modes of the electric machine in the overall vehicle system.

Together with Volkswagen AG and TU Ilmenau, we are working on the development of suitable models for fault types and fault propagation in the overall system as well as algorithms for fault detection. A prototype implementation with subsequent validation on the test bench and in the vehicle is also planned.

In addition to basic investigations, test bench investigations and on-board diagnostics of possible fault modes are planned, as well as investigations of acoustic and thermal effects of individual faults, including real-time signal processing.Finally, the feasibility and restrictions of the diagnostic capability are to be demonstrated by validation both on the test bench and in the vehicle. In addition, a transmission will be tested with regard to operability for different user groups.
