Abstract

A method for pairing a wireless charging system to a vehicle, includes: determining location coordinates of a target position of a vehicle parking space within a parking lot; storing the location coordinates of a center of the parking space; receiving a signal including location coordinates of the vehicle; and determining a location match using the location coordinates of the center of the parking space and the location coordinates of the vehicle to pair the wireless charging system to the vehicle.

Claims

1. A method of pairing a wireless charging system to a vehicle, the method comprising steps of:

transmitting, by a processor, a first signal including location information related to a parking space within a parking lot;

receiving, by the processor, a second signal from the vehicle including an array of received signal strength indicators (RSSI), wherein the array is determined from a plurality of signals within the parking lot, wherein the RSSI is measured in response to the transmission of the first signal, the array of RSSI is calculated based on the measured RSSI, and a value of the measured RSSI is displayed by a gray scale;

recognizing, by the processor, RSSI patterns in the calculated array of RSSI, wherein the RSSI patterns are recognized by the gray scale;

storing, by the processor, the recognized RSSI patterns;

determining, by the processor, a location of the parking space based on the received second signal;

comparing, by the processor, the array of RSSI with previously stored arrays of RSSI;

determining, by the processor, a match between the array of RSSI and one of the previously stored arrays of RSSI using a signal processing algorithm; and

transmitting, by the processor, a third signal providing a match notification to the vehicle that indicates the pairing of the wireless charging system to the vehicle.

2. The method of claim 1, wherein the first signal is transmitted from the vehicle.

3. The method of claim 1, wherein the RSSI patterns are based on repeated parking attempts of the vehicle.

4. The method of claim 1, further comprising a step of:

using a global positioning system to pair the wireless charging system to the vehicle.

6. The method of claim 1, further comprising a step of:

in response to determining that the array of RSSI is unmatched with one of the previously stored arrays of RSSI, storing, by the processor, the unmatched array of RSSI.

5. A non-transitory computer readable medium containing program instructions executed by a processor on a controller, the computer readable medium comprising:

program instructions that transmit by a first signal including location information related to a parking space within a parking lot;

program instructions that receive a second signal from the vehicle including an array of received signal strength indicators (RSSI), wherein the array is determined from a plurality of signals within the parking lot, wherein the RSSI is measured in response to the transmission of the first signal, the array of RSSI is calculated based on the measured RSSI, and a value of the measured RSSI is displayed by a gray scale;

program instructions that recognize RSSI patterns in the calculated array of RSSI, wherein the RSSI patterns are recognized by the gray scale;

program instructions that store the recognized RSSI patterns;

program instructions that determine a location of the parking space based on the received second signal;

program instructions that compare the array of RSSI with previously stored arrays of RSSI;

program instructions that determine a match between the array of RSSI and one of the previously stored arrays of RSSI using a signal processing algorithm;

program instructions that transmit a third signal providing a match notification to the vehicle that indicates the pairing of the wireless charging system to the vehicle; and

program instructions that store the array of RSSI in response to determining that the array of RSSI is unmatched with one of the previously stored arrays of RSSI.
