Patent attributes
A control device for a vehicle comprised of an electric power supply control part controlling the supply of electric power to electrical equipment and an electric power transfer control part controlling the transfer of electric power between a first battery and a second battery. The electric power supply control part supplies the electric power of the second battery to a catalyst device if the electric power which can be output by the first battery is smaller than the total demanded output electric power of the electrical equipment and a need arises to supply electric power to the catalyst device so as to warm up the catalyst device. The electric power transfer control part supplies electric power of the first battery to the second battery if the electric power which can be output by the first battery is larger than the total demanded output electric power of the electrical equipment, the state of charge of the second battery is less than a predetermined first state of charge considered required when using the electric power of the second battery to warm up the catalyst device, and a temperature of the catalyst device is less than a predetermined temperature.
