Designing and Experimental Study of Automated Mechanical Transmission

The authors analyze major factor influencing the vehicle starting and shifting character of electronic-control AMT. By taking the mini-vehicle of Chan'an Star as carrier, electronic-control hydraulic AMT is developed, comprehensive shift-control strategy and clutch joint-control strategy are constitued, and related factors affecting clutch joint disciplinarian are complemented. The authors also put forward control aim of engine speed in the process of vehicle start and shifting, and automatic control to engine speed is realized by adopting electronic throttle. A last tests on prototype vehicle start &shift are made under different working conditions. The result shows newly-developed automatic transmission system is of more satisfactory control effect.
