Advanced automotive system design and development requires a multidisciplinary and intersectoral approach connected to the integration of new powertrain concepts, such as electric and hybrid ones. This approach involves knowledge concerning the NVH issues, and/or electric motor, associated power electronics to control motor speed and torque, the transaxle that transfers the mechanical energy to the wheels, the battery and its management unit, etc.
The present proposal answers to two challenges of the electrification of the passenger cars: (i) noise-vibration-harshness (NVH) issues connected to the electric driveline integration and (ii) new advanced modelling and testing tools able to answer to the high integration level of electric vehicles (EVs).
The main objective of DeMoTest-EV aims the development of advanced and extended design, modelling and testing tools for improved concept modelling and for higher prediction accuracy of noise and vibration generated by EVs powertrain. The achievement of the objective will be possible by enhancing knowledge, know-how and technological transfer between four European partners bringing together their experience in electrical machines and drives, NVH issues in automotive, modelling and testing tools for automotive applications. The mechanisms used for the transfer of knowledge within the frame of the project are collaborative research, two-way intersectoral secondments, sharing facilities, training and dissemination activities.
