Integrated Powertrain Control of Gearshift for Automatic Transmission

Abstract

In this paper, an integrated powertrain control of gearshift for automatic transmission is developed: engine control by torque regulation is incorporated to suppress the shock of output shaft torque, whilst a clutch slip controller is applied to transfer the engine torque to driveline system, which is aimed to regulate clutch slip speed. The proposed approach ensure the powertrain system stable, and the shift time can be controlled by clutch slip controller even if with the absence of engine control. At last, taking 1-2 upshift for example, simulation results are presented and discussed in the final chapter of this paper.

Integrated Powertrain Control for Gear Shifting

“…The coordinated engine control for gear shifting is another important aspect of integrated powertrain control. Much important research has been done on coordinated engine control [7,8,[11][12][13][14]]. An electronically controlled throttle was used in [7,11]; ignition timing was adjusted in [8,11,12]; fuel injection quantity was tuned in [14].…”
