As the mobility becomes complex, the coopertion of test and simulation is more and more important. For several years, various technologies for hybrid methods of test and simulation, such as VPT, FBS decoupling, modal model, SEMM and auralization have been studied and developed to help virtual development activities. As a result, the model based roadnoise development process and dedicated softwares have been developed. In this study, the system models such as tire blocked force, suspension FRFs and body FRFs were made by experiment and simulation and assembled to predict vehicle’s roadnoise. As a objective evaluation, roadnoise was analysed and the systematic TPA and sensitivity analysis process and program were development to set reasonable system targets to meet vehicle target. Then, as a subjective evaluation, roadnoise were auralized for various driving conditions such as speeds and road types according to driver’s input.
