Abstract Structure and shifi characteristics of dual-clutch transmission （DCT） were analyzed, and the dynamic model of shift process was established. The rules for the fixed engine speed with constant engine speed between torque transfer of the clutch and throttle angle were established. The control strategy for 1 st gear launch using single clutch and two clutches working together was established. The control strategy for 2nd gear launch using single clutch and two clutch worked together was also established for high throttle angle situation. The disk was easily raised to high temperature in the crawl driving condition. In order to get ride of the disadvantage, the control strategy for two clutch slip was established by turns. The separation integral PID algorithm was used to follow the speed of the target. The simulation results show that the control strategy for launch using two clutches work together can share the overall slipping power and is advantageous for clutch enduring life.
