초록 In recent years, for the convenience of the user, an automatic transmission is mounted on a vehicle as the transportation means. Nevertheless, there is a proclivity for a great number of vehicles to use DCT(Dual Clutch Transmission) systems which have the characteristics and advantages of a manual transmission rather than an automatic transmission with low power transmission efficiency. By applying the advantages of manual transmission, DCT achieves higher fuel efficiency and faster shifting than the conventional automatic transmission which usually utilizes hydraulic control. Especially, in order to enable quick shift, DCT moves the gear of the non-drive shaft directly to the gear that user wants to reach. Additionally, we performed the fault diagnosis with measuring the hydraulic line pressure of tractor, hydraulic oil temperature, synchronizer position; with judging gear, an analysis on the state of clutch output is also performed by MATLAB / Simulink.
