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 for wireless charging of a vehicle at one of a plurality of previously authorized wireless charging station locations authorized prior to the vehicle being within a specified range of the wireless charging station locations, the method comprising, by a vehicle computing system:

retrieving the locations of the previously authorized wireless charging stations; and

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

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 of the initial signal 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 the specified range of one of the previously authorized vehicle wireless charging station locations.

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 one of the previously authorized wireless charging station locations; 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 one of the previously authorized wireless charging station locations.

11. A system for vehicle wireless charging, comprising:

a vehicle computing system having a transceiver and a processor programmed to transmit an initial wireless signal from the transceiver to establish communication with a wireless charging station in response to a comparison of a current vehicle location to a location of the wireless charging station indicating the vehicle is within a specified range of the wireless charging station, and to not transmit the initial 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 initial 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.
