Research on simulating and modelling dynamics of double clutch transmission (DCT)

Shifts in a dual-clutch transmission (DCT) are realized by torque transfer from one clutch to another without traction interruption. Thus the shift raw is quite important for the performance of DCT. Analyzing the dynamics and its raw of DCT, dynamic model and the control logic for the integrated vehicle are built using Matlab/simulink as the simulation platform in this paper. With a given input parameters such as throttle position, braking pedal position, etc. the transmission shift quality, impact index are assessed and the effectiveness of the shift control is validated as well.
