摘  要:
For the shift control problem in the test-bed system of double clutch transmission(DCT),the composition of the test-bed has been introduced firstly in the paper. Then the principle of the gear-position selecting actuator, the gear-shifting actuator and the clutch controlled by PID controller are described. The dynamic law of the gear shifting is analyzed, the simulation model is established by using Matlab/Simulink. Simulation calculation has been implemented. The result of the test-bed has exhibited the law of the gear shifting, ensured the stability in the process of DCT shifting, improved the shifting quality of the test-bed system of double clutch transmission(DCT).
