Abstract

As of December 2016, the number of registered automobiles in Korea exceeds 21million. As a result, greenhouse gas emission by transportation sector are increasing every year. It was concluded that the development of the driving strategy considering the driving behavior and the road conditions, which are known to affect the fuel efficiency and the greenhouse gas emissions, could be the most effective fuel economy improvement. Therefore, this study aims to develop a fuel efficient driving strategy in a complex linear section with uphill and curved sections. The road topography was designed according to 'Rules about the Road Structure & Facilities Standards'. Various scenarios were selected. After generating the speed profile, it was applied to the Comprehensive Modal Emission Model and fuel consumption was calculated. The scenarios with the lowest fuel consumption were selected. After that, the fuel consumption of the manual driver's driving record and the selected optimal driving strategy were compared and analyzed for verification. As a result of the analysis, the developed optimal driving strategy reduces fuel consumption by 21.2% on average compared to driving by manual drivers.

2016년 12월 기준 우리나라 자동차 총 등록대수는 2100만대를 넘어섰으며, 이러한 영향으로 교통부문 온실가스 배출량도 매해 증가하였다. 연비와 온실가스 배출량에 영향을 미치는 주요 요인으로 알려진 주행 행태와 도로 조건을 고려한 주행전략을 개발하여 주행을 할 때, 높은 연비 개선 효과를 누릴 수 있을 것으로 판단하였다. 이에 본 연구는 오르막 구간과 곡선구간이 있는 복합 도로선형 구간에서의 연료 효율적인 주행전략 개발 및 연료소모량 절감 효과 분석을 목적으로 하였다. 도로의 시설 기준에 관한 규칙에 따른 도로지형을 설계하고, 다양한 시나리오를 선정하여 속도프로파일을 생성한 후, Comprehensive Modal Emission Model에 적용하여 연료소모량을 도출하였다. 연료소모량이 최소인 시나리오를 선택하였으며, 검증을 위해 일반 운전자의 주행과 최적주행전략의 연료소모량을 비교 분석하였다. 분석 결과, 최적 주행전략이 일반 운전자의 주행보다 연료소모량을 평균 21.2% 절감하는 것으로 나타났다.
