The intelligent down-shift control for wet dual clutch transmission

In order to solve the problems existed in gearshift with wet dual clutch transmission, the down-shift control strategy was developed on the basis of analysis on gear shift process. Clutch pressure intelligent control arithmetic based on FCMAC(Fuzzy Cerebellar Model Articulation Controller) was designed to realize accurate control of clutch pressure. The transmission control units is designed. And down shifting control strategy was drawed, then the control program is written into TCU. After applied the introduced method into the experiments on both power-on and power-off downshift, ideal shifting quality was achieved. The result indicated that the speed of vehicle changed without distinct impact. This essay verifies the validity of the proposed method of the strategy of shifting control.
