Hydraulic Control System

Dual clutch transmission (DCT) combines the advantages of AMT and AT. This paper selects a certain type of dry DCT as the study object. The structure and working principle are introduced. A shift dynamic model is established to analyse the five phases of shift process. The oil line diagram of the electro-hydraulic control system is provided, and then the characteristics of the proportional solenoid valves which are critical control components of DCT are studied. The analysis results provide theoretical basis and guidance for the design and development for DCT.
