In this paper, on the basis of a simplified hybrid model of an Automated Manual Transmission (AMT) system with servo-actuated clutch and gearbox, the control strategy for the gearshift is formally addressed as a hybrid optimal control problem and solved by means of numerical optimization method. The gear upshift request is performed with locked clutch and achieving the synchronization of the requested gear by exploiting engine cut-off and properly controlling the engine and the gearbox. Performance achievable with the proposed strategy under various vehicle conditions and engine regimes are shown.
