| Abstract: | The structural features and working principles of a new type dual-clutch transmission(DCT) of selective output are described.The whole dynamic model of automotive DCT control system is established by the simulation software Matlab/Simulink/SimDriveline,including engine,controller,automatic transmission and vehicle body.The whole system of DCT is simulated,and the engine speed,vehicle velocity,and the working conditions of gear and clutch are obtained.A good coincidence between the simulation results and the theoretical analysis indicates that the DCT model is reasonable and feasible.This modeling and simulation method improves the design efficiency of DCT dynamic system.The corresponding results provide necessary preparations for the further development of DCT control strategy. |
