CGST 하이브리드 시스템의 다물체 동역학 해석 및 제어 알고리즘

Automated Manual Transmission(AMT) and Dual Clutch Transmission(DCT) are applied to hybrid vehicle as a transmission system recently and they achieved better fuel efficiency in comparison with traditional Continuously Variable Transmission(CVT) hybrid vehicle. But there are some problems about torque cutoff, shift shock, energy loss and failure during gear shifting by use of clutch in AMT & DCT system. The Clutchless Geared Smart Transmission(CGST) solves these problems by substituting Planetary Gear System(PGS) and motor control for traditional clutch and also it is superior to AMT & DCT system in fuel efficiency, cost, durability, weight and size. In addition, the hybrid vehicle with CGST can perform Idle Stop & Go in city traffic to maximize the fuel efficiency. To perform Idle Stop & Go and support smooth gear shift in CGST hybrid system, it is required to use different control algorithm as compared with traditional hybrid transmission system. So in this research, We suggest the new control algorithm of CGST hybrid system and show the Multibody Dynamic analysis result by use of this algorithm.
