N2 - Drivability and fuel economy are continuously emphasized during the development of automobiles, and shift quality is the most important part of the drivability. To improve the shift quality, the integrated powertrain control strategy for gear shifting is presented in this paper. First of all, the transmission control strategy based on the turbine speed trajectory is proposed. Furthermore, an output torque observer is determined to implement the coordinated engine control, and then the torque based coordinated engine control is presented. Finally, the integrated powertrain control strategy is studied by experiments. The experimental results show that the integrated powertrain control reduces the shift jerk and the dissipated clutch energy during gear shifting.
