Simulation and Experimental Verification of AMT Control Strategy Based on Powertrain Physical Model Built in Amesim

The physical model of transmission built in Amesim can provide detailed movement process data of the actuators. A method for building a physical model of the powertrain of AMT in Amesim are proposed owing to the advantage above. To verify the accuracy of the model, the launch, gear selecting and shifting control strategy models of an AMT are built in Simulink, and the launch and accelerating process with jump shifting from the 2nd, the 4th to the 6th gear fully loaded on a level road are performed through the Co-Simulation platform of Amesim and Matlab/Simulink. Simultaneously, a bench test of gear selecting and shifting actuator and a real truck test are carried on. The simulation results are close to the experimental data. The simulation and experimental results show that the proposed method has a relative higher accuracy, which can improve the efficiency of AMT control strategy development.
