In a hybrid vehicle, rotational speed control on a motor/generator connected to a first engagement clutch is carried out when there is a gear shift request to a gear shift stage at which the first engagement clutch of the multistage gear transmission is meshingly engaged. A transmission control unit is provided for outputting a meshing engagement instruction to the first engagement clutch when a rotational speed feedback control causes a differential rotation speed of the first engagement clutch to be within a range of a synchronization determination rotational speed. Upon executing the rotational speed feedback control on the motor/generator, this transmission control unit reduces the efficacy of the rotational speed feedback control less than before starting of the meshingly engagement, when the meshing engagement of the first engagement clutch is started.
