When the shift stage of a transmission is not being changed, a change gear ratio Gr of a transmission is calculated by setting an inputted rotation speed Nm 2 as a control rotation speed Nm 2*, and when the shift stage of the transmission is being changed, the change gear ratio Gr is calculated by setting the rotation speed that is obtained by adding a value obtained by multiplying a difference DeltaNm 2, which corresponds to the time differential component of the rotation speed Nm 2, by a gain km to the rotation speed Nm 2 (S 130 to S 160 ). By using these, torque commands Tm 1* and Tm 2* of motors MG 1 and MG 2 are set so that the engine is operated at an operation point represented by a target rotation speed Ne* and a target torque Te*, by which the engine and the motors MG 1 and MG 2 are controlled.
