    Abstract: An electric vehicle having an electrical storage battery includes an inductive charge receiver configured to inductively couple to charging coils embedded in a roadway over which the vehicle travels in order to transfer charge to the storage battery. A ground penetrating radar transceiver is configured to interrogate the roadway including a region of the roadway toward which the vehicle is heading. The ground penetrating radar transceiver generates reflectance data including reflections from the charging coils. An object analyzer is responsive to the reflectance data and configured to map the charging coils relative to the vehicle. A path controller is configured to determine a steering operation of the vehicle along the roadway for optimizing a charge transfer from the charging coils to the inductive charge receiver.

    Abstract: A wireless power transfer system that performs wireless power transfer by magnetic coupling between a supply device on a ground and a vehicle on traveling, includes: a control device that controls wireless power transfer from a power transmitter of the supply device to a power receiver of the vehicle. Further, the control device determine that a coupling deviation has occurred in the magnetic coupling in a case where a state in which received power in the power receiver is smaller than a target value by a predetermined value or more has continued for a predetermined time period during the wireless power transfer from the supply device to the vehicle; and performs a state transition to Magnetic Coupling Check to confirm a coupling coefficient of the magnetic coupling in a case where the control device has determined that the coupling deviation has occurred.

    Abstract: This application provides a wireless charging board, a wireless charging board misalignment detection method, and a wireless charging system. The wireless charging board includes a power transmitting coil, a detection circuit, a plurality of metal induction coils, and a processor. Each metal induction coil disposed on a second plane in the wireless charging board detects, through induction, whether a metal exists right above the metal induction coil, and generates an induced electrical signal. The processor determines charging position misalignment information of the wireless charging board. According to this application, an adjustment range during alignment between a target charging working region and the wireless charging board can be expanded, thereby ensuring that a sufficient adjustment space is left for a driver, and achieving high applicability.
