Starting control takes an important role in the system of Automated Mechanical Transmission (AMT); clutch engagement control is the key of it. For the purpose to improving the starting performance of AMT, this paper develops the relation between clutch engaging speed and starting jerk, the relation between engine rotate speed and the friction work in starting process. According to the relations, a starting control strategy of keeping the engine rotate speed constant is putted forward in this paper. The main idea of the strategy is to keep the engine run at a lower rotating speed and don't make it flameout through controlling clutch engagement distance and clutch engagement speed in starting process. Based on the strategy, the clutch control map figures which individually correspond with throttle opening, engine rotate speed and difference between clutch master and slave plate rotate speed are built. Finally the paper applies the principle and the control methods successfully on Santana 2000
