An upper rotational speed limit NengUL and a lower rotational speed limit NengLL of an engine operation prohibition area are set from an upper rotational speed limit Nmg2UL and a lower rotational speed limit Nmg2LL of a motor operation predetermined prohibition area of a second motor generator. When an engine speed target Nengt, calculated from a preset target operating line, lies in the engine operation prohibition area, the engine operating point target is corrected so that the second motor generator rotational speed target Nmg2t lies outside the motor operation prohibition area. When the engine speed target Nengt is greater than or equal to a change-direction engine speed NengCD at which direction of shift to/from an allowable range of engine operation is changed, the engine speed Neng is increased. When the engine speed target Nengt is less than the change-direction engine speed NengCD, the engine speed Neng is decreased.
