Starting Control Based on Wet Dual Clutch Transmission

Abstract:

Aimed at the problem of starting control of dual clutch transmission equipped with wet clutch, the starting strategy was developed on the basis of clutch c ontrol evaluation and dynamics analysis about transmission. The clutch pressure control method was proposed based on fuzzy PID control, and the detailed fuzzy control process was developed. The control flow of DCT starting was determined s o that the clutch actual pressure got better control. Starting experiments of th ree different throttle and continuous startstop experiments in a short time we re executed. The experimental results verified the rationality of the control st rategies. It could meet the requirements of smooth and rapid vehicle starting, a nd establish the foundation for the further development of DCT.
