摘要：

During the starting process of single clutch, the temperature rise of clutch plate is obvious and the sliding friction power is uneven, which seriously affects the service life of DCT. Based on the configuration of P2.5 plug-in hybrid electric vehicle equipped with DCT, combined with the starting dynamics analysis and considering the driver's starting intention, a starting strategy based on multi-layer fuzzy control is proposed. The driver's starting intention is identified according to the accelerator pedal opening and its change rate, and the clutch combination oil pressure is deduced according to the starting intention to control the transmission torque, at the same time, the clutch separation threshold is judged according to the driver's starting intention. The results show that: compared with single clutch starting, the starting time can be shortened by 12.6% and the impact degree can be reduced by 14.0% while effectively balancing the sliding work of the two clutches. © 2021, Jilin University Press.
