Abstract
An approach module determines that a wireless power transfer (WPT) secondary pad on a vehicle approaching a WPT primary pad is within an approach distance threshold from the WPT primary pad. A pulse module generates an electrical alignment pulse in the WPT primary pad or WPT secondary pad in response to determining that the WPT secondary pad is within the approach distance. A measurement module determines an amount of magnetic coupling between the WPT primary pad and the WPT secondary pad, and a feedback module that provides an alignment signal to a driver of the vehicle. The alignment signal represents magnetic coupling. The pulse module continues to provide electrical alignment pulses, the measurement module continues to determine an amount of magnetic coupling in response to the electrical alignment pulses, and the feedback module continues to provide alignment signals indicative of an amount of magnetic coupling as the vehicle moves in relation to the WPT primary pad.
