| Abstract: | In order to enhance competitive ability of Chinese automotive enterprises,the paper introduces the structure and working principles of a new type Dual-clutch Transmission(DCT) with patented.And based on the simulation software of Matlab/Simulink,the whole dynamic model of automotive DCT control system is established,including engine,dual clutch automatic transmission,vehicle body and other loadings.Then the shift process of DCT is simulated and the control strategy is researched.The simulation results indicate that the DCT model is reasonable and feasible,and improves the design efficiency of DCT dynamic system.The results of simulation and research prove that this method is correct and usable. |
