Abstract
The control apparatus of the present invention is applied to a hybrid vehicle that, as power sources for propulsion, includes an internal combustion engine that can change over between lean combustion and stoichiometric combustion, and motor-generators. The control apparatus performs the noise suppression control in which the operating points of the internal combustion engine are limited so as to suppress noise generated by a power transmission mechanism, and changes over the operational mode of the internal combustion engine if the thermal efficiency when performing the noise suppression control by changing over the operational mode of the internal combustion engine is higher than the thermal efficiency when performing the noise suppression control by keeping the operational mode of the internal combustion engine the same.
