An upper speed limit NengUL and a lower speed limit NengLL of a prohibition range of the operation of the engine are set from the upper speed limit Nmg2UL and the lower speed limit Nmg2LL of a predetermined prohibition range of the operation of a second motor generator. When an engine speed target Nengt calculated from a preset target operating line is within the prohibition range of the operation of the engine, the engine operating point target is corrected such that the rotational speed target of the second motor generator Nmg2t is out of the prohibition range of the engine operation. If the engine speed target Nengt is greater than or equal to a direction change engine speed NengCD at which the direction of the shift is changed to and from an allowable range of operation of the engine, the engine speed Nengt is increased, while if the engine speed target Nengt is less than the direction change engine speed NengCD, the engine speed Neng is reduced.
