Abstract
본 연구에서는 주행하는 차량에서 관심 도로면의 형상을 재현할 수 있는 시스템을 제안하였다. 차체에 부착된 센서로부터 측정된 신호에 혼입된 차량의 동적 거동 영향을 배제하고 형상 정보를 재현할 수 있는 멀티 센서 시스템을 적용하였고, Lab 실험을 수행하여 센서부에 인가되는 동적 외란에 대해서도 강건한 성능을 검증하였다. 실제차량에 시스템을 구현하여 다양한 도로면에 대한 검증 실험을 수행하였으며 해석적 노면 모델과의 비교를 통하여 그 효용성을 제시하였다. This paper presents the development of the surface profile sensing system (SPSS) and its application to analysis of road surface. The SPSS which can robustly reconstruct the road input profiles from the intermixed data with the vehicle's dynamic motion, is implemented using the multi-sensor system with the optimally shaped transfer function. The performance of this system is evaluated by a series of experimental works in the devised simulator. And a real car test equipped with the proposed system is performed in the proving ground over both deterministic and random road surfaces. Finally, a feasibility of the system is investigated considering the road model.
