| Abstract: | The clutch control is the key to shifting process control of automatic transmission. Effective clutch state information contributes to accuracy clutch control. By predictive model of the actuator for the clutch is established with the help of finite element simulation, a method of estimating clutch status online through a predictive model is proposed..The model is operated in a microcontroller, and the results are compared to those of a platform test, which indicates that the model can run online and effectively forecast oil pressure and flow of the clutch. |
