Electric and plug-in hybrid electric vehicles include a rechargeable traction battery. An automated vehicle charging system is configured to charge the traction battery with minimal operator intervention. The vehicle charging system includes at least one tire pad including a plurality of pressure-sensitive sensors arranged at known locations of the tire pad and outputting signals having a magnitude indicative of a pressure applied by a tire at the known locations. The vehicle charging system also includes at least one controller programmed to receive the signals and control movement of a transmit coil according to a position of the tire on the tire pad that is derived from the signals. The known locations may be generally equally spaced or unevenly spaced across the tire pad. The tire pad may include a tire stop to limit motion of the tire in one direction.
