차량 동역학 시뮬레이션을 위한 도로 변위 및 속도 신호의 생성

The road signal is generated by white random noise which is passed through FIR filter according to ISO standard. In addition the road velocity signal is made by the derivative of the displacement signal using cubic spline which has relatively good differential gain and phase. The generated road signal enables tire to have damping characteristics which is sometimes omitted due to the difficulty in generating road velocity profile.
