Electrical and hybrid vehicles development opens a whole new field of noise and vibration challenges. From the motor noise generation to the emission in the cabin, a wide range of possible axis of progress can be proposed. For that, a wide variety of testing techniques and their corresponding tools have been developed and are discussed in this web-based presentation.

NVH new challenges

First, a quieter cabin environment, relieved from the ICE noise, let new sources emerge. Those sources often generate low sound levels but with unworked sound design, providing a poor sound experience to the passenger. On its side, the main propulsion motor plays a major role in the overall sound

Electromagnetic noise sources characterization

The electromagnetic noise generated by motors is specific and requires its own specific experimental approach. Unique testing tools used to characterize electromagnetic noise are described from spatiograms and electric markers to psychoacoustics indicators.

Transfer Path Analysis

Noise reduction challenges can be tackled at the source but also by mitigating the noise on its way to the cabin. Structures of EV/HVs have been largely modified compared to traditional ICE vehicles and transfer paths need to be reconsidered. Describing OROS innovative TPA techniques and solutions, this subject is addressed in the presentation.
