Abstract
Based on the theory of Inverse Fast Fourier Transform (IFFT), the method of the time domain model of four road tracks is suggested. In addition to considering the coherence of left track and right track as well as the fact of time delay between rear track and front one of the vehicle, a method of the excitation of four wheels is derived. Through the simulation with different roads, the feasibility of proposed method is well verified.
