The acoustic quality of a product is an important factor regarding the purchase decision. Due to the growing market share of electric and hybrid vehicles, the electric drive train as a source of noise is becoming more important. In this contribution the measurement and interpretation of these noises are focused. The contribution is based on a cooperation of the IPEK (Institute of Product Engineering at the Karlsruhe Institute of Technology) and the Daimler AG within the Promotionskolleg edrive.

1 Motivation

The driving comfort is a factor of importance for buying decisions. Especially for electric vehicles the acoustic quality is an elementary distinguishing feature, since the masking of an internal combustion engine (ICE) is no longer present [1]. Opposing the importance of the acoustic quality is the lack of knowledge of how to measure, interpret and rate the high frequency noise generated by an electric powertrain [2].

In the contribution of the sound sources depending on the...



The measurements, which this contribution is based on, were performed within the Promotionskolleg edrive financed by the state Baden-Württemberg and the Daimler AG on an anechoic powertrain test bench of the Daimler AG. Particular acknowledgments are due to all persons, who supported and consulted thus enabling the success of the measurements.
