Abstract
A vehicle is provided with a coil and a sensor. The coil is adapted to receive power wirelessly in single-phase form from an external coil. The sensor is adapted to measure a characteristic of the power. The vehicle is also provided with a controller that is programmed to estimate a parameter indicative of coil alignment using a three-phase representation of the power based on the characteristic, and to adjust the power received by the coil based on the parameter.
