Abstract: Aiming at the problem of frequent shift during the driving of vehicle， the fuzzy reasoning method was used to identify driving intention，and the shift performance of dual clutch transmission （DCT） under the traditional shift control strategy was studied. A method of the DCT fuzzy shift control strategy was presented based on the traditional shift control strategy and the driving intention recognition. The simulation model of DCT based on Matlab/Simulink was established， the effectiveness of fuzzy shift control strategy of DCT based on driving intention recognition was verified by comparing with the DCT performance simulation results of traditional shift control strategy. The results indicate that the shift control strategy could effectively reduce the frequency of shifting，the phenomenon of frequent shift is eliminate during the driving of vehicle. The riding comfort of driver and the vehicle safety is improved.

Key words: DCT; driving intention recognition; shift control strategy; fuzzy control
