Abstract：It is of significance to establish the time domain model of road for the theoretical research of modern vehicle. Harmony superposition method is applied to establish the road roughness of a single wheel. Two kinds of method are proposed to calculate the coherence of bilateral tract excitation, combined with the correlation of front and rear wheel, road roughness model of 4-wheel vehicle is built. Simulation results show that the two modeling method is correct in theory of coherence and can be applied to simulate stochastic road with a specific spectrum. Compared with other methods, proposed methods improve the efficiency of modeling.
