Launch control of wet dual clutch transmission based on fuzzy logic

To solve the problems existed in vehicle starting with wet dual clutch transmission, the starting strategy was developed on the basis of clutch evaluation and dynamics analysis about transmission. The wet clutch target pressure of starting phases is determined by fuzzy control method. Parameter adaptive PID controller was used to realize clutch pressure´s accurate control. In order to verify the validity of the control strategy, real vehicle starting tests were done. The results show that this strategy could meet the needs of ride and rapidness in the starting process, and the starting quality of vehicle is satisfying.
