5속 자동변속기 기반 하이브리드 자동차의 변속 및 가속지연 시뮬레이션 = Shift and Acceleration Response Lag for a Hybrid Electric Vehicle with 5-speed Automatic Transmission

다국어 초록 (Multilingual Abstract)

In this paper, shift quality and acceleration lag for automatic transmission(AT) based HEV are investigated to verify the application feasibility of 5-speed AT without torque converter for a 2-shaft parallel HEV. A performance simulator based on AMESim is developed using the dynamic models of the HEV powertrain such as ISG, engine, motor and 5-speed automatic transmission. It is found that the peak to peak torque variation in the inertia phase increases for the HEV mode due to the added torque and inertia effect of the ICE engaged by the engine clutch, and the shift quality for the EV and HEV mode can be improved by the motor torque control. In addition, acceleration lag for the mode change is evaluated when the HEV is launched from the stand still state to the HEV mode.
