Abstract

The interest in reducing the emissions and increasing the fuel economy of ICE vehicles has prompted research on hybrid vehicles, which come in the series, parallel, and power-split types. This study focuses on the series-type hybrid electric vehicle, which has a simple structure. Because each component of a series hybrid vehicle is larger than the corresponding component of the parallel type, the sizing of the vehicle is very important. This is because the performance may be greater or less than what is required. Thus, in this research, the optimal fuel economy was determined and simulated in a real-world system. The optimal sizing was achieved based on the motor, engine/generator, and battery for 13 cycles, where DP was used. The model was developed using ASCET or a Simulink-Amisim Co-simulation platform on the rapid controller prototype, ES-1000.

직렬형 하이브리드 자동차는 구조가 간단하고 단품들의 효율이 높기 때문에 연비성능이 우수하며, 병렬형과 비교하여 배터리, 엔진, 모터의 용량이 상대적으로 고용량인 특징을 가진다. 본 연구에서는 직렬형 하이브리드 자동차의 최적용량매칭을 통해 최적의 연비를 도출하고, 실시간 시뮬레이션 환경에서 사용될 알고리즘을 개발한다. 연구에서 진행된 용량매칭은 모터, 엔진/발전기 및 배터리를 대상으로 13개 주행 사이클에 대하여 순차적으로 이루어 졌으며, 이를 위해 Matlab 환경에서 최적화 기법인 DP(Dynamic Programming)을 사용하였다. 실시간 성능검증을 위한 차량모델은 Simulink 및 AMEsim을 기반으로 개발되었고 실시간 제어로직이 구현된 RCP(Rapid Control Proto-typing)와 연동하여 그 성능을 확인할 수 있었다.
