Abstract: Introduce the dynamic friction coefficient of clutch friction plate. Establish Mathematical model of starting process, carried out vibration analysis for frictional sliding process systematically, validated the analysis using Matlab/simulink software. Meanwhile, compared with the starting process by static friction coefficient. The results show that using dynamic friction coefficient to analyse starting process conforms to the actual working condition.

Abstract: Based on the analysis of Dual clutch transmission (DCT) working principle, the shift kinetics model is established, and the power switching rule between two clutches during upshift and downshift is established by analyzing the torque transmission relationship of vehicle driveline system during shifting, then shift process is tested on actual vehicle with Matlab/Simulink software. Comparing the two different kinds of downshift processes, and illuminating the effect on engine control by various downshift control rules, the downshift process is optimized.
