A Novel Gear Shifting Strategy for Dual Clutch Transmission System Using Reverse Engineering and Robust Design Technique

European Union legislation sets mandatory emission and fuel consumption reduction targets for new vehicles and therefore economy remains a key challenge for automotive engineers. Optimizing the transmission shift schedule for an automatic transmission with double clutch is an important part of improving fuel economy. Using simulation and optimization algorithms can ensure that a truly optimal shift schedule is implemented. The main objective of this paper focuses on study the performance of a vehicle with a dual clutch transmission (DCT), with special emphasis on optimizing the shifting schedule using optimization algorithms. In order to study and simulate the shifting strategy the dynamic model is developed based on an existing model in MATLAB Simulink software. In the first phase of the paper a detailed description of the DCT technology, its main functional components and dynamic characteristics are explored. In the second phase model development and simulation concerns the major part of this work, to find the optimal shift schedule for different engine speed and engine torque as it accelerates through the transmission gears by engaging the dual clutches. Finally, the simulation results were evaluated and presented which successfully demonstrate the performance improvement of a dual clutch transmission with an optimized shifting strategy.

Dual Clutch Transmission (DCT) is a new automatic transmission system, which overcomes the shortcomings of power break when shift of the automatic mechanical transmission (AMT) and not only inherit high transmission efficiency and simple structure of AMT, but also inherit small impact of hydraulic, non-power interruption characteristics of automatic transmission (AT). The core and difficulty is the clutch control in the start process, the control targets are not only to ensure the smoothness of the start process and stable operation of the engine, but also to ensure quickness[1].
