하이브리드 자동차의 과도응답 특성 구현을 위한 동력 시스템 모델링에 관한 연구

다국어 초록 (Multilingual Abstract)

This paper presents a dynamic model of a parallel HEV (Hybrid Electric Vehicle) which can simulate torque vibration during transient maneuvers. The target HEV has and engine clutch between the engine and the traction motor; and has a ISG (Integrated starter & generator) to start the engine after EV(electric vehicle) mode. In this configuration, the drive-train torque vibration during transient maneuver is one of the major issues due to the discontinuity of the engine clutch. However, because of lack of the dynamic model of the system, the research for the issues heavily depends on the actual test; and the control strategy is hard to be designed from the systematic approach. Therefore, as the first step for the development of the systematic supervisory control strategy, this paper focuses on the dynamic modeling and validation of the parallel HEV.
