<P>PROBLEM TO BE SOLVED: To achieve efficient power feeding with a simple structure in a power feeding system and a vehicle using a resonance technique. <P>SOLUTION: A communication device 150 sends a detection value of reflection power RF of a high-frequency power supply device 110 in a power feeding facility 100 from the power feeding facility 100 to a vehicle 200. The vehicle 200 includes an impedance matching device 230 to adjust impedance of a resonance system, which is configured by a resonator for power transmission composed of a primary self-resonant coil 130 and a primary coil 120, and a resonator for power reception composed of a secondary self-resonant coil 210 and a secondary coil 220. The impedance matching device 230 is controlled based on the detection value of the reflection power RF received from the power feeding facility 100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
