  • LKAS(Lane Keeping Assistance System) main function is to support the driver in keeping the vehicle within the current lane. Therefore, this system is able to reduce the driver workload with assisting the driver during driving. In this paper, we presented on study for test procedures and evaluation methods of the LKAS. The vehicle test conducted on straight road, left curve, right curve and four different types of lane under various vehicle speeds. This study proposed the LKAS system test procedures and methods that we are able to identify LKAS driving mechanism and performance.

  • Lane Keeping Assistance System(LKAS) is a kind of Advanced Driver Assistance Systems(ADAS) which are developed to automate/ adapt/ enhance vehicle systems for safety and better driving. The main system function of LKAS is to support the driver in keeping the vehicle within the current lane. LKAS acquires information on the position of the vehicle within the lane and, when required, sends commands to actuators to influence the lateral movement of the vehicle. Recently, the vehicles equipped with LKAS are commercially available in a few vehicle-advanced countries and the installation of LKAS increases for safety enhancement. The test procedures for LKAS evaluations are being discussed and developed in international committees such as ISO(the International Organization for Standardization). In Korea, the evaluations of LKAS for vehicle safety are planned to be introduced in 2016 KNCAP(Korean New Car Assessment Program). Therefore, the test procedures of LKAS suitable for domestic road and traffic conditions, which accommodate international standards, should be developed. In this paper, some bullet points of the test procedures for LKAS are discussed by extensive researches of previous documents and reports, which are released in public in regard to lateral test procedures including LKAS and Lane Departure Warning System(LDWS). Later, it can be helpful to make a draft considering domestic traffic situations for test procedures of LKAS.

And then, to evaluate the validity of the proposed test procedures, a series of experiments were conducted using commercially available two vehicles equipped with LKAS. Later, it can be helpful to make a draft considering domestic traffic situations for test procedures of LKAS.

  • 현대사회의 자동차 산업은 교통사고를 예방하고 운전자의 운전 부담을 줄이기 위해 첨단 운전 보조 장치(ADAS)를 개발 해왔다. ADAS중 차선유지지원장치(LKAS)는 안전과 운전 향상을 위해 차량 시스템을 자동화시키기 위해 개발되었다. LKAS의 주요 역할은 현재 차선 내에서 차량을 유지하는데 있어 운전자를 도와주는 것이다. LKAS는 레이더센서와 카메라센서를 사용하여 차선 내에서 차량의 위치에 대한 정보를 수집하고 필요한 경우 엑츄에이터에 명령을 전송하여 차량의 측면 이동에 영향을 미친다. 최근 LKAS가 장착된 차량 일부가 일부 선진국에서 상용화되며 안정성이 증가되었다. 국제적으로 LKAS 평가를 위한 시험절차는 ISO(International Organization for Standardization)와 UNECE(United Nations Economic Commission for Europe)와 같은 국제위원회에서 논의하며 개발중이다. 한국에서는 차량 안전을 위한 LKAS의 평가가 KNCAP(Korean New Car Assessment Program)에 의해 도입될 예정이다. 따라서 국제표준에 부합하는 국내 도로환경에 적합한 LKAS의 시험 절차가 개발되어야한다. 본 논문에서는 국내도로환경에 맞춘 LKAS 시험시나리오 개발 및 목표 상대거리를 구하는 수식을 제안한다. 그리고 제안한 시나리오와 수식을 평가하기 위해 LKAS가 장착된 상용차량을 사용하여 시험평가를 진행하였다.
