Progress in NVH Technology for Future Mobility

New means of transportations will not mean just new ways of travel but will change the way we live our lives, and it also naturally affects related technologies. It would be meaningful to look at how those changes of future mobility affect NVH technology. Five different personal mobility futures can be envisioned, which emerge from the intersection of two critical trends - vehicle ownership and vehicle control - and is represented by a whole new type of mobility. It would be desirable for us to assume these five mobility states as a possible scenario in the future and explore the necessary technical opportunities. Research papers and patent data were analyzed to extract trends in technology topics using unstructured text-data analysis, and the ideas of technical needs were derived from strategic landscaping and scoping. Some of the examples of how these technical opportunities are being developed are introduced. The structural changes in electric vehicle noise will need new engineering approaches, and active control technology can be used more widely as the space inside mobility is expected to have various forms. Active convergence with other fields such as virtual reality, machine learning, mobile communication, and data science is also a new trend of progress. Furthermore, synesthesia technology using sound and vibration will be needed when emotional driving is to be provided beyond autonomous driving. NVH technology for future mobility should provide various types of solutions that are organically linked.
