4 steps to predict road noise – a project with Hyundai Motor Group

November 18, 2022

Road noise has become the dominant noise source in electric vehicles, but predicting it is notoriously difficult. Simcenter and Hyundai Motor Group took a new approach to virtual NVH development. Using MBSE, they could assess road noise across a range of driving conditions and vehicle variants at each stage of development.
