V2I 통신 기반 에코 드라이빙을 이용한 커넥티드 하이브리드 자동차 연비 향상에 관한 연구

Abstract

In this paper, the improvement in the fuel economy of a connected hybrid electric vehicle(CHEV) that uses eco-driving with V2I communication is investigated through simulation. The simulation environment uses an integrated driving hardware-in-the-loop(IDHIL) simulator that was built in a previous study. Vehicle-to-everything(V2X) communication devices are used to preview information from traffic lights, and is then used to induce eco-driving behavior in the driver. The normal HEV and CHEV use the same HCU. The HCU consists of a mode decision algorithm and a power distribution algorithm. The scenario reflects the virtual road environment and traffic lights through field measurements. The NHEV and CHEV are simulated three times each, and the vehicle speed, SOC, and fuel consumption results are presented. The simulation results are also compared in terms of speed and engine operating point. In this paper, we found that fuel consumption can improve by 14.32 % if V2I communication-based eco-driving is used.
