Mode Transition Control of Plug-In Hybrid Electric Vehicle During Clutch Engagement

摘要

Proper mode transitions in plug-in hybrid electric vehicles (PHEVs) can improve the vehicle efficiency. However, the transitions consume energy and affect drivability whenever the clutch engages. In this paper, we propose a mode transition control, including two strategies during clutch engagement. One is an engine torque generating for the reduction of a sudden change of acceleration. The other is a clutch actuating rapidly after a sufficient condition of clutch. A PHEV simulator evaluated the energy consumption and vehicle acceleration of these two strategies. In conclusion, we found that the mode transition control helped to improve the drivability and energy efficiency.
