Abstract

In this paper, engine clutch engagement shock is analyzed during the mode change of plug-in hybrid electric vehicles. Multi-driving mode includes the EV (electric vehicle) mode, HEV (hybrid electric vehicle) mode, and engine operating mode. Depending on the mode change, the engine clutch is either engaged or disengaged. The magnitude of shock during clutch engagement is very important because it impacts vehicle acceleration and clutch synchronization speed, which affects ride comfort substantially. The performance simulator of plug-in hybrid electric vehicles was developed using MATLAB/Simulink. The simulation results show that the mode change control algorithm is necessary for minimizing shock during clutch engagement.

플러그인 하이브리드 전기자동차는 내연기관과 전기모터를 동력원으로 사용하며 주행 상황에 따라 다양한 주행 모드을 갖는다. 주행 모드에는 전기모터로만 주행하는 EV 모드(전기주행), 내연기관으로 주행하는 엔진 운전 모드, 두 개의 동력원을 이용하는 HEV 모드(하이브리드 주행)가 있다. 특히 병렬형 구조를 갖는 하이브리드 전기자동차는 모드변환에 따라 엔진 클러지가 접합되거나 해제되는데, 클러치 접합 시 나타나는 충격은 차량의 승차감에 영향을 주기 때문에 중요하다. 본 논문에서는 플러그인 하이브리드 전기자동차의 성능 시뮬레이터를 MATLAB/Simulink를 이용하여 개발하고, 시뮬레이션 결과를 통해 엔진 클러치 접합 시 나타나는 충격 특성을 분석하였다.
