초대형 트럭용 자동화 수동 변속기의 성능 분석

Due to the increase of the oil price, the needs for the fuel efficiency improvement of the vehicles are growing and as environmental problems like CO₂ emission be issues, many automotive companies have developed various new technologies to deal with those issues. Automated Manual Transmission(AMT) is one of those technologies. AMT, based on conventional manual transmission, uses various control units and actuators to automate the clutch actuation and gear shift. As manual transmissions main clutch is applied to supply the power from the engine to transmission, compared to the torque converter applied to automatic transmission, AMT improves fuel efficiency and has better responsibility due to the varied shift mode. Also comparing to automatic transmission, it provides the same ease. This paper is to analyze heavy duty track applied AMTs structure, performance characteristics, automated shifting. And compare the data from real vehicle experiments to study the responsibility of shifting control and stability.
