Clutch control is a critical issue for Automated Manual Transmission (AMT) and it is related to the vehicle drivability closely, such as the jerk during gear shift and the friction loss during the clutch slip process. In this paper, a clutch control strategy is developed during gear shift process, wherein two key problems are considered. A shaft torque observer-based clutch disengagement controller is proposed during clutch release process, and a disturbance rejection controller is applied to clutch engagement control. The plant and control-oriented models of the powertrain are built, then the gear upshift process from the first gear to second gear is taken as an example to validate the proposed clutch control strategy. The simulation results show that, the drivability during the gear shift process can be guaranteed, the shift time is short enough, whilst the clutch slip loss and vehicle jerk also satisfy the requirements.
