Abstract
The parking assistance device is used in a wireless power supply system which performs wireless power supply between the power transmitting coil on a ground side and the power receiving coil on a vehicle side, and includes: three or more coils aligned in one direction in a plan view of the vehicle, the coils configured to detect magnetic flux in a height direction of the vehicle which is generated by the power transmitting coil; and a misalignment detection unit configured to detect misalignment between the power transmitting coil and the power receiving coil in the one direction, based on a decrease in the magnetic flux in the height direction of the vehicle which is detected by the three or more coils.
Claims6
A parking assistance device used in a wireless power supply system which performs wireless power supply between a power transmitting coil on a ground side and a power receiving coil on a vehicle side, the parking assistance device comprising:
- three or more coils aligned in one direction in a plan view of the vehicle, the coils configured to detect magnetic flux in a height direction of the vehicle which is generated by the power transmitting coil;
- and
- a vehicle controller configured to detect misalignment between the power transmitting coil and the power receiving coil in the one direction, based on a decrease in the magnetic flux in the height direction of the vehicle which is detected by the three or more coils.
A parking assistance method used in a wireless power supply system which performs wireless power supply between a power transmitting coil on a ground side and a power receiving coil on a vehicle side, the parking assistance method comprising:
- detecting magnetic flux in a height direction of the vehicle which is generated by the power transmitting coil, by using three or more coils aligned in one direction in a plan view of the vehicle;
- and
- detecting misalignment between the power transmitting coil and the power receiving coil in the one direction, based on a decrease in the magnetic flux in the height direction of the vehicle which is detected by the three or more coils.
