Abstract

In this paper, we devise a new ontology-based context-aware system to recognize the smart car information, in which driver's intent is utilized by information of car, driver, environment as well as driving state, driver state. So proposed system can handle dynamically risk changes by adding real-time situational awareness information. We utilize the camera image recognition technology for context-aware intelligent vehicle driving information, and implement information acquisition scheme OBD-II protocol to acquire vehicle's information. Experiments confirm that the proposed advanced driver safety assist system outperforms the conventional system, which only utilizes the information of vehicle, driver, and environmental information, to support the service of a high-speed driving, lane-departure service and emergency braking situation awareness.

본 논문에서는 주행상황의 자동차 정보를 인식하기 위하여 차량, 운전자, 환경 정보와 함께 주행상태 정보, 운전자상태 정보를 추가하여 실시간으로 바뀌는 운전행동에 대한 정보를 상황인식에 활용하여 운전자의 의도를 반영할 수 있도록 하였으며, 온톨로지 기반 상황인식 모델을 구성하여 다양한 상황에서의 상황인식이 가능하게 설계하였다. 상황정보의 획득방법으로 운전자 정보와 주행정보는 카메라를 이용한 영상인식 기술을 활용하며, 자동차 정보는 OBD-II 프로토콜을 이용한 정보 획득 장치를 이용한다. 실험결과 운전자 상태정보와 주행정보의 분석을 통하여 운전자 의도를 반영한 제안 시스템이 고속주행 상황에서의 차선이탈 경고 서비스 및 저속주행 상황에서의 안전거리 경보서비스를 위한 상황인식에 있어서 기존의 차량, 운전자, 환경정보를 활용한 방식보다 운전자 안전지원 서비스에 우수한 성능을 확인할 수 있었다.
