In vehicle driving simulations, modelling the tyre precisely is not easy due to the nonlinear effects of tyre deformation. Instead of precise tyre modelling, this paper proposes to regenerate the road profile, which preserves the measured wheel acceleration with a linear tyre model in computer simulations. Frequency response functions between the road and the wheel are used to regenerate the road profile. The error function between the experimental results and the simulation results is defined, and the new road profile is generated by iteration to reduce the error function. From the full car example, the proposed method in this paper shows very good results, and thus the new method seems well suited in virtual driving simulations.
