Control System Integration for Dual Clutch Transmissions Based on Modular Approach

Abstract:

Modular approach has been adopted in this paper to divide DCT transmission control unit into four modules, which are clutch control, synchronizer control, shift assembly control and vehicle control respectively. The function for each module has been analyzed and the control logic relations among these modules have also been established for modular integration. Moreover, the modeling process and control strategies for each module have been established for respective control objection. On this basis, the simulation model of transmission control unit for DCT has been built using the Matlab/Simulink platform, and the simulation has been carried out at given throttle opening. The results show that the control strategy of transmission control unit for DCT has been validated, which provides theoretical basis for DCT product development.
