Modeling and Simulation Research of Dual Clutch Transmission Based On Fuzzy Control

摘要

Dual-Clutch Transmission (DCT) is one kind of new automatic transmission which has double clutch structure. The most important unit of DCT is Transmission-Control Module (TCM). In the development process of TCM, simulation is an important research tool. We have analyzed the DCT principle of work, established its mathematical model, created the charge and discharge oil models of typical wet dual-clutch transmission, established the control logic to unify and separate double clutch in turn, and also designed out the shift control using fuzzy control using MATLAB/Simulink software. Utilizing engine model, driver model, the DCT model, the TCM model, the vehicle model, established the vehicle simulation model, and implemented simulation; Result indicated that, the established model can correctly reflect the torque and speed change when shifted gears and can correctly realize the automatic shift gears.
