Abstract

The time domain model of vehicle road is the key component of road database. Model regeneration in time domain by using time series method, based on the road statistical digital feature PSD in frequency domain or on road test data sequence is featured with efficiency and universality. Following the general road formulation, two different realization ways with respect to the appointed PSD of a standard road and to the test sampling data sequence are illustrated. The modeling process and the determination of model parameters are analyzed in the paper. The AR and ARMA models are established as road regeneration models in time domain. Simulation study has demonstrated that the method is reasonable and efficient.
