SYSTEM TO ALIGN A VEHICLE WITHIN A PARKING LOCATION USING THERMAL TARGETS
First Claim
1. A system to align a vehicle in a parking location, said system comprising:
- a plurality of heat generating devices arranged in a surface of said parking location to produce a distinctive thermal pattern;
a multiple zone temperature sensor mounted so as to have a sensor field of view including said plurality of heat generating devices and configured to output thermal data indicative of a zone temperature for each of the zones;
a controller in communication with the multiple zone temperature sensor;
a memory device storing instructions that, when executed, cause said controller to receive the thermal data from said multiple zone temperature sensor and determine a thermal map of said plurality of heat generating devices forming an array of thermal data cells, wherein each thermal data cell has a temperature value based on a temperature characteristic of one or more of the zones; and
a display in communication with said controller, said display providing a graphic indication of the thermal map and a thermal alignment target.

Abstract
A system to align a vehicle in a parking location includes a plurality of heat generating devices, such as infrared LEDs, arranged in a surface of the parking location to produce a distinctive thermal pattern. A multiple zone temperature sensor is mounted to view the heat generating devices and is configured to output thermal data for each of the zones. A controller is configured to receive the thermal data and determine a thermal map of the plurality of heat generating devices. A display provides a graphic indication of the thermal map and a thermal alignment target. The system may be used to align a vehicle having a capture resonator of a wireless power transfer system to a parking location having a source resonator of a wireless power transfer system.
