Abstract

Recent development in science and technology has enabled vehicles to be equipped with advanced autonomous functions. ADAS (Advanced Driver Assistance Systems) are examples of such advanced autonomous systems added. Advanced systems have several operational modes and it has been observed that drivers could be unaware of the mode they are in during vehicle operation, which can be a contributing factor of traffic accidents. In this study, possible mode confusions in a simulated environment when vehicles are equipped with an adaptive cruise control system were investigated. The mental model of the system was designed and verified using the formal analysis method. Then, the user interface was designed on the basis of those of the current cruise control systems. A set of human-in-loop experiments was conducted to observe possible mode confusions and redesign the user interface to reduce them. In conclusion, the clarity and transparency of the user interface was proved to be as important as the correctness and compactness of the mental model when reducing mode confusions.

최근 과학 기술의 발전으로 첨단 자율 기능을 탑재된 차량의 출현이 가능하게 되었으며, 기존 차량에 추가된 첨단 운전자 지원 시스템(Advanced Driver Assistance Systems: ADAS)은 기존 차량에 추가된 이러한 자율 시스템들의 좋은 예라 할 수 있다. 이러한 시스템은 다수의 작동 모드를 가지는데 운전자들이 현재 수행중인 작동 모드를 잘못 인지하게 되면 교통사고가 일어날 수 있음이 관찰되고 있다. 본 연구에서는 적응 순항제어(Adaptive Cruise Control: ACC) 시스템을 장착한 자동화된 자동차의 운전자 인터페이스를 설계하고 이를 정형 기법을 통한 분석과 피실험자를 이용한 실험을 통해 모드 혼동 발생 여부를 검증하고 이를 개선하는 연구를 수행하였다. 이를 통해 모드 혼동을 방지하기 위해서는 시스템에 대한 심성 모델의 정확성과 간결성뿐만 아니라 인터페이스 구현시 디스플레이의 명확성이 또한 매우 중요하다는 것을 확인하였다.
