Abstract
An automotive vehicle includes a vehicle-based charging unit including a receiving unit configured to receive power from a ground-based charging unit, the receiving unit including a multi-coil receiver, a first actuator operably coupled to the vehicle-based charging unit and configured to adjust a first position of the vehicle-based charging unit relative to the ground-based charging unit, and a controller configured to selectively actuate the first actuator. The controller is configured to receive first performance indicator data indicating a first alignment between the charging units, determine an alignment error between the charging units and calculate a first position adjustment of the vehicle-based charging unit, automatically control the first actuator to implement the first position adjustment of the vehicle-based charging unit, and receive second performance indicator data indicating a second alignment between the charging units, the second alignment resulting in a desired power transfer efficiency between the charging units.
