摘　　要：提出了电动干式双离合器轿车的整车综合控制策略。采用CANoe-Matlab联合仿真的方法建立了带有DCT系统的整车模型,并对其CAN网络进行仿真;向CAN总线收发DCT换挡过程中所需的报文和共享信息,重点验证了总线的运行情况和实时性。整车试验结果表明,通过CAN总线使TCU与ECU之间进行实时通信,对发动机、双离合器和变速器三者进行协调控制,能够有效提高DCT轿车的换挡品质,实现其动力换挡。An integrated control strategy for a car equipped with electrical dry-type dual-clutch is introduced in the paper. Then a vehicle simulation model with DCT is built in Matlab/Simulink co-simulation method, and its CAN network is simulated. The message and shared information required in the shifting process of CAN bus receiving and sending DCT validates bus operating condition and real-time performance. The vehicle test results show that CAN bus enables real-time communication between TCU and ECU, coordinated control between engine, dual clutch and transmission, can effectively improve shifting quality of car equipped with DCT and achieve power shifting.
