Abstract: For misalignment measurement, a method receives a plurality of position detection signals from a corresponding plurality of detection coils. The plurality of position detection signals are generated from mutual inductance between the plurality of detection coils and an energized field-generating detection coil. The method further generates detection information from the position detection signals. In addition the method calculates a lateral misalignment along a lateral Y axis from the detection information. The lateral misalignment includes a lateral misalignment distance and a lateral misalignment direction. The method calculates a vehicle speed along a longitudinal X axis from the detection information. In addition, the method energizes a transmitter power coil and controls the power transfer based on the vehicle speed and lateral misalignment.

Abstract: A vehicle including a power receiving pad for wirelessly receiving power, a plurality of magnetic sensors for measuring a magnetic field of a power transmitting pad and obtaining magnetic field data, one or more processors, and one or more memory modules are provided. The one or more memory modules include a computer-readable medium storing computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to receive the magnetic field data from the plurality of magnetic sensors, and estimate a lateral misalignment of the power receiving pad with respect to a magnetic axis of the power transmitting pad. The magnetic sensors are arranged to detect at least an X-component and a Y-component of a magnetic field produced by a power transmitting pad.
