Abstract

A system and method for managing communications with a vehicle wireless charging station include a vehicle having a battery configured for wireless charging and a vehicle computing system having a transceiver and a processor programmed to broadcast a signal by the vehicle computing system using the transceiver to establish a communication link with a vehicle wireless charging station in response to a current vehicle location being within a specified range of a previously authorized vehicle wireless charging station. The system and method may include a vehicle HMI to prompt a user for input to authorize communication with a wireless charging station that is not recognized or that has not been previously authorized. Wireless charging related broadcasts may be inhibited when the vehicle is not within a specified range of a known wireless charging station location to conserve energy and reduce potential for unauthorized responses to the vehicle broadcasts.

Claims

1. A method performed by a vehicle computing system of a vehicle having a battery configured for wireless charging, comprising:

broadcasting a signal by the vehicle computing system to establish a communication link with a vehicle wireless charging station in response to a current vehicle location being within a specified range of a previously authorized vehicle wireless charging station, and not broadcasting the signal in response to the current vehicle location being outside the specified range.

2. The method of claim 1 further comprising receiving a GPS signal by the vehicle computing system to identify the current vehicle location.

3. The method of claim 1 further comprising enabling WiFi communications by the vehicle computing system in response to the current vehicle location being within the specified range of the previously authorized vehicle wireless charging station.

4. The method of claim 1 further comprising displaying a message via a vehicle HMI in response to the current vehicle location being within a specified range of a vehicle wireless charging station that has not yet been authorized.

5. The method of claim 1 wherein the broadcasting is performed only in response to the current vehicle location being within the specified range.

6. The method of claim 1 further comprising:

receiving, by the vehicle computing system, a request to establish communication with a vehicle wireless charging station; and

communicating with the vehicle wireless charging station only if the current vehicle location is within a specified range of a previously authorized vehicle wireless charging station.

7. The method of claim 1 further comprising receiving authorized vehicle wireless charging station locations by the vehicle computing system over a wireless communication link.

8. The method of claim 1 further comprising receiving authorized vehicle wireless charging station locations by the vehicle computing system from a vehicle HMI.

9. The method of claim 8 wherein the vehicle HMI receives a signal from a mobile device identifying a vehicle wireless charging station location.

10. The method of claim 1 further comprising:

receiving, by the vehicle computing system, a request to establish communication with a vehicle wireless charging station;

displaying a message via a vehicle HMI requesting authorization to communicate with the vehicle wireless charging station if the vehicle wireless charging station is not recognized by the vehicle computing system; and

communicating, by the vehicle computing system, with the vehicle wireless charging system in response to authorization received via the vehicle HMI, or if the vehicle wireless charging station is recognized.

11. A system for vehicle wireless charging, comprising:

a vehicle computing system having a transceiver and a processor programmed to transmit a wireless signal from the transceiver to establish communication with a wireless charging station in response to a current vehicle location being associated with a location of the wireless charging station, and to not transmit the wireless signal in response to the current vehicle location not being associated with the location.

12. The system of claim 11, the processor further programmed to transmit the wireless signal only if the current vehicle location is associated with the location of a previously authorized wireless charging station.

13. The system of claim 11 further comprising a vehicle HMI, the processor further programmed to display a message on the vehicle HMI in response to receiving a signal from an unrecognized wireless charging station.

14. The system of claim 11, the processor further programmed to send a message to a vehicle HMI in response to the current vehicle location being within a specified range of a wireless charging station that has not been authorized.

15. The system of claim 11, the processor further programmed to store a location of a wireless charging station in response to user input received from a vehicle HMI.

16. The system of claim 11, the processor further programmed to transmit the wireless signal in response to receiving a wireless signal from the wireless charging station if the wireless charging station was previously authorized by the vehicle computing system.

17. A computer readable storage medium having stored instructions executable by a vehicle computing system to transmit a signal to establish communication with a wireless charging station only in response to a vehicle location being within a range of a location associated with the wireless charging station.

18. The computer readable storage medium of claim 17 further comprising instructions to transmit the signal in response to receiving a signal from the wireless charging station if the location of the wireless charging station is recognized by the vehicle computing system.

19. The computer readable storage medium of claim 17 further comprising instructions to display a message on a vehicle display in response to receiving a wireless signal from a wireless charging station that has not been previously stored by the vehicle computing system.

20. The computer readable storage medium of claim 17 wherein the location of the wireless charging station is stored as an authorized location in the vehicle computing system.
