Abstract
A vehicle alignment system is adapted to align a vehicle with a wireless power induction coil for wireless charging through use of magnetic resonant induction. The system includes a leaky transmission line disposed so as to align the vehicle left-right in a parking slot containing the wireless power induction coil when the vehicle is aligned for charging by the wireless power induction coil. At least two vehicle mounted antennas mounted on opposite sides of a left-right center line through the wireless power induction coil when the vehicle is aligned in the parking slot containing the wireless induction coil receive the operating frequency from the leaky transmission line, and signal processing circuitry detects a relative signal phase between signals induced by switching between antennas on opposite sides of the leaky transmission line. The relative phase differences between the detected signals from the antennas are representative of alignment of the vehicle with respect to the wireless power induction coil and the parking slot.
