Alignment method for a vehicle wireless charging structure
First Claim
1. An alignment method for a vehicle wireless charging system, the method comprising:
- detecting reception of electromagnetic radiation received by a vehicle-side coil from a transmitter coil with the vehicle-side coil at a current position relative to the transmitter coil;
determining efficiency of electromagnetic radiation reception by the vehicle-side coil;
determining whether or not the efficiency of electromagnetic radiation reception by the vehicle-side coil achieves a predetermined level of reception efficiency;
repositioning the vehicle-side coil in response to determining that the efficiency of the electromagnetic radiation reception is less than the predetermined level of reception efficiency; and
repeating the determining of the efficiency of electromagnetic radiation reception and the repositioning the vehicle-side coil until the determined efficiency is equal to or greater than the predetermined level of reception efficiency.

Abstract
An alignment method for a vehicle wireless charging system, that includes detecting reception of electromagnetic radiation received by a vehicle-side coil from a transmitter coil with the vehicle-side coil at a current position relative to the transmitter coil. Other steps include determining efficiency of electromagnetic radiation reception by the vehicle-side coil, and determining whether or not the efficiency of electromagnetic radiation reception by the vehicle-side coil achieves a predetermined level of reception efficiency. Further steps include repositioning the vehicle-side coil in response to determining that the efficiency of the electromagnetic radiation reception is less than the predetermined level of reception efficiency, and repeating the determining of the efficiency of electromagnetic radiation reception and the repositioning the vehicle-side coil until the determined efficiency is equal to or greater than the predetermined level of reception efficiency.
