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.
