英文摘要：

The control system of dual clutch transmission is designed based on 32-bit Microcontroller MPC5604. The＇ shifting schedule is established, and the shifting control strategy is put forward. Furthermore, the action sequences of clutch and synchronizer are designed in the launching and shifting process. The multi-task control system is implemented based on the structure characteristics and performance requirement of DCT, and the multi-task schedule method is presented on the basis of the table-driven approach. The function of the control system is verified in the test platform of xPC560B, the results show the system operates reliably, and achieves the control aims of the launching and shifting process.
