There is an undeniable trade-off in new electric and hybrid vehicles regarding its sound quality. Comfort and sound brand perception compete with safety related issues, because their current quietness and low detectability endanger vulnerable road users. This new scenario requires the traditional strategy of noise reduction to be reconsidered and re-shaped into a more refined strategy based on the improvement of noise quality, annoyance reduction and improved vehicle recognition. This is the reason why its development for the next generation of vehicles requires international cooperation of multiple disciplines in electrical and mechanical engineering. Even fields of emerging importance such as sound quality, NVH, advanced automatic control, multiphysics modelling, vehicle integration and functional safety have to be taken into account, which require specific disciplinary know-how combined with multi-disciplinary co-design and multi-domain optimization. In this context, SS4S (Sound shaping for safety in the next generation of electric vehicles) will create a unique interdisciplinary network of leading OEMs, automotive industries, automotive research companies and top European universities to successfully write research and training oriented proposals to address the major sound quality challenges of the next generation of vehicles. The result of this project will be the presentation of a MSCA proposal under Horizon Europe (2021-27). From previous collaborations, potential partners are Ferrari, Maserati or Volvo (as OEMs), Brose, Kolektor (as Tier1 suppliers), AVL, IDIADA, Siemens Software or Virtual Vehicle (as research centers), EARPA (as automotive association) and INSA-Lyon, KU Leuven or University of Ljubljana (as universities), with IDIADA (Spain) and KU Leuven (Belgium) being the key partners. UPC has previously collaborated with these partners positively and the definitive consortium will be finally decided once the new calls of Horizon Europe specify the recommended number of PhD candidates. The SS4S proposal will ensure a highly-experienced consortium in the sound quality of light-weight e-drives areas, encompassing sound and vibration analysis of light-weight automotive e-drives including the human perception, NVH analysis and control strategies for auxiliary e-drives, and the integration and complete vehicle level evaluation of sound quality related to e-drives. From a human resources point of view, the future recruited researchers, following structured PhD programmes in top European universities, will receive latest training not only in the above technical domains but also, they will expose to entrepreneurs skills (from business schools like ESADE), training activities and secondments in order to build up the future leaders. ESRs will be able to provide specific solutions to the European industry and society, this being a cornerstone in the career of each trained researcher.
