In a state in which a vehicle travels while an internal-combustion-engine driving torque (Te) is transmitted to drive wheels, Te and a clutch torque Tc are decreased and an electric-motor driving torque (Tm) is increased based on the satisfaction of a shift-up condition (t1). Thereafter, based on the fact that Tc becomes zero (t2), a shift-up action is carried out while maintaining Tc to zero and maintaining a state in which Tm is transmitted to the drive wheels (t2 to t3). Then, based on the termination of the shift-up action (t3), Te and Tc are increased and Tm is decreased (t3 to t5). During the time period from the satisfaction of the shift-up condition to time at which Tc becomes zero (t1 to t2), a load torque (Ts) of a power generator rotationally driven by an output shaft of the internal combustion engine is generated. In a hybrid vehicle equipped with an AMT, power consumption with the driving of an electric motor when the shift-up action is carried out using the assist of the electric-motor torque can be reduced.
