Parking assistance apparatus and system
First Claim
1. A parking assistance apparatus that assists with parking of a movable vehicle in a parking area in which a power-supplying coil wirelessly supplying electric power to a power-receiving coil provided in the movable vehicle is installed, the parking assistance apparatus comprising:
- a plurality of exciting coils installed in the parking area, the plurality of exciting coils having no connection with a power supply; and
a plurality of resonators connected to the respective exciting coils and set to resonate due to leakage magnetic flux of the power-supplying coil,wherein the plurality of exciting coils generate, due to the leakage magnetic flux, magnetic fields whose magnitudes are different from one another.
