Abstract: Precise dynamic model of engine is the foundation of making shift schedule and realizing optimal match of vehicle powertrain. The dynamic torque and fuel consumption models of engine are built through neural network identification. Based on that, a calculating method of dynamic shift schedule with 3-paramters is put forward. The application in AMT test vehicle shows that the dynamic shift schedule with 3-parameter based on neural network model of engine is superior to the shift schedule with 2-parameter in dynamic performance and fuel economy.
