FIELD: electricity.

SUBSTANCE: parking assistance device is used in a wireless power supply system that performs wireless power supply between an electric power transmitting coil on the ground side and an electric power receiving coil on the vehicle side. The device contains three or more coils and a misalignment detection unit. The coils are aligned in one direction in the top view vehicle and are arranged to detect a magnetic flux in the vertical direction of the vehicle that is generated by the electric power transmitting coil. The misalignment detection unit is configured to detect misalignment between the electric power transmitting and receiving coils in one direction on the basis of the reduction in the magnetic flux in the vertical direction of the vehicle, that is detected by the aforementioned coils.

EFFECT: detection of misalignment between the electric power transmitting coil and electric power receiving coil.
