Abstract
The coordination of engine will influence the starting and shifting quality of AMT. Heretofore, the study on this aspect is mainly limited to the engine torque control. But for the difficulty of installing torque sensor, just open loop control is adopted, so that the effects don't be satisfactory. This paper puts forward the strategy of engine constant speed control in starting and shifting process, based on the view of kinematics and dynamics. The main idea is that the target speed of engine is constituted according to the different throttle opening, and the deviation between the target speed and the actual speed will be limited through clutch control and fuel injection control in starting and shifting process, which not only greatly reduce the work of slipping and prolong the life of the clutch, but also reduce the fuel consumption and the noise, improve the shift quality in starting and shifting process.
