<P>PROBLEM TO BE SOLVED: To provide a power supply system for a vehicle which can suppress an increase of space and weight when a battery and a capacitor are used together. <P>SOLUTION: The power supply system for the vehicle includes a generator 20 for the vehicle which generates power by being driven by an engine, the battery 10 charged by the generator 20 for the vehicle, and the capacitor 40 connected in parallel to the battery 10 via a relay 60. The capacitor 40 is charged by the relay to feed operation power to an in-parking operation system 50 which operates during the parking of the vehicle. A voltage of the operation power fed to the in-parking operation system 50 from the capacitor 40 is set to a value lower than a terminal voltage of the battery 10 and higher than an internal voltage of the in-parking operation system 50. <P>COPYRIGHT: (C)2010,JPO&INPIT |
