| Abstract: | Transmission shift control strategy in parallel hybrid electric vehicle(PHEV) system is studied in this paper.The state-drive between motor and engine are investigated,and automatic transmission shift off switch cycle is kept.A computation model of power and fuel efficiency of motor and engine is established,and an efficiency shift curve worked out.The results show that the described control strategy can make the PHEV transmission shift comfortable and improve driving performance. |
