[차량운동성능부문] 차량 동역학 시뮬레이션을 위한 도로면 형상 측정 기술 개발

Road profiling is a means to measure the surface contour of road. The measured road profiles can provide the research organizations with valuable data to perform vehicle testing and computer simulations. Many road profile measuring systems have been developed up to the present. As the Dynamic Road Profiling Devices(DRPD), An Accelerometer Established Inertial Profiling Reference (AEIPR) method is to measure the elevation of the road surface to a certain degree of accuracy along the direction of travel at a normal highway speed. This paper describes to construct DRPD and the signal processing for advanced double integration and road profiling for AEIPR method. The measured road profiles using the methods are in good agreements with real road elevation.
