45 The Study of Dual Clutch Automatic Transmission (DCT) Control System Available to Purchase

Aiming at the poor stability and the big friction work in the dual clutch automatic transmission speed changing process, and according to the dual clutch automatic transmission structure characteristics, this paper studies the timing sequence of the dual clutch transmission torque and the engine torque in the shift process, and the program flow chart is given in this paper. The control method in this paper achieves the clutch pressure and the engine timing sequence precisely controlled. This project established the relevant test condition bench, and the experimental results show that the design of the dual clutch automatic transmission (DCT) control system presented in this paper solves the smooth shift problem of the automobile.
