<P>PROBLEM TO BE SOLVED: To improve fuel consumption for a vehicle by making effective use of regenerated electric power. <P>SOLUTION: This control device for vehicular power supply has a first power generation power supply and a second power generation power supply, and supplies electric power from the respective power generation power supplies to a prescribed power receiving part. The device is provided with a voltage adjusting means (steps S2, S3) for setting the voltage outputted to the power receiving part from one of the first power generation power supply, and the second power generation power supply according to the output voltage of the other power generation power supply. As a result, excessive power is prevented from being supplied to the power receiving part. If the electric power is regenerated at the second power generation power supply, effective use of the electric power can be made, thus improving fuel consumption of a vehicle. <P>COPYRIGHT: (C)2003,JPO |
