With unique configuration characteristic,dual-clutch transmission(DCT)overcomes the shortcoming of power interruption when shifting in traditional AMT,which results in good power performance,fuel economy and driving comfort,and recently it becomes a new development trend in the field of transmission.Basing on the analysis of starting control principle of DCT,control principle and method that both the dual clutch engaged in the starting process simultaneously with engine constant speed are proposed.And the starting characteristic of the dry dual-clutch transmission is simulated and analyzed,providing theory foundation for the development and research of the dual-clutch transmission.
