Software Architecture Design of Dual Clutch Transmission Control System

Abstract:

From the view of software development mode and architecture,the control system of dual clutch transmission (DCT) is analyzed.Based on the kernel of the embedded real time operating system μC/OSⅡ,the software architecture of DCT control system is established.The complicated control of DCT shifting process is implemented by using finite state machine (FSM),and DCT control system is developed according to the software architecture of control system.In the platform of DCT hardwareintheloop simulation,the function and performance of control system software are tested.The results show that the software can not only ensure the realtime requirements of DCT control system,but also enhance its stability and scalability.

Key words:dual clutch automatic transmission; embedded realtime operating system; μC/OSⅡ; finite state machine; software architecture
