The AMT can either automatically shift gears using appropriate actuators mounted on manual transmission (MT) according to driver’s power command and driving conditions, or in accordance with driver’s gear command through shifting level. Conventional AMT for vehicles powered by internal combustion engine (ICE) requires an electronic controlled clutch to separate or engage engine power to the MT for gear change smoothly, because of high inertia of the ICE, which complicates the system and thus with high cost. In this study, an AMT design without the use of the clutch for electric vehicle (EV) is studied. The idea is mainly based on the fact that the inertia of the power motor of EV is generally quite small compared with that of the ICE. This enable synchronize electronically the rotating speed of driving gears with driven gears in the MT gearbox during the gear change operations. This thesis introduces the design of the CL AMT and its feasibility was verified through a test rig. Chyuan-Yow Tseng Chih-Hsien Yu 曾全佑 余致賢 2011 學位論文 ; thesis 76 zh-TW |
