Abstract

A system and method for determining whether a handheld communication device (HCD) is located inside a vehicle includes: receiving at a central facility a request to locate the HCD; sending a message to the vehicle with an instruction to determine if the HCD is present in the vehicle; receiving a response from the vehicle that indicates whether or not the HCD is present in the vehicle; and transmitting a message to a user of the HCD indicating whether the HCD is located inside of the vehicle.

Claims

1. A method of determining whether a handheld communication device (HCD) is located inside a vehicle, comprising the steps of:

(a) receiving at a central facility a request to locate the HCD;

(b) sending a message to the vehicle with an instruction to determine if the HCD is present in the vehicle;

(c) receiving a response from the vehicle that indicates whether or not the HCD is present in the vehicle; and

(d) transmitting a message to a user of the HCD indicating whether the HCD is located inside of the vehicle.

2. The method of claim 1, further comprising the step of sending the message to the vehicle with an instruction to determine if the HCD is communicating with a vehicle telematics unit via a short-range wireless communication protocol.

3. The method of claim 1, further comprising the step of sending the message to the vehicle with an instruction to begin listening for an acoustical signal that is generated by the HCD.

4. The method of claim 3, further comprising the step of determining whether the acoustical signal is detected at the vehicle.

5. The method of claim 1, further comprising the steps of receiving a smart phone identifier at the central facility and transmitting the smart phone identifier to the vehicle.

6. The method of claim 1, further comprising the steps of receiving a vehicle identifier at the central facility and transmitting the vehicle identifier to the vehicle.

7. The method of claim 1, further comprising the step of transmitting from the central facility to a second central facility an instruction for the HCD to generate an acoustical signal.

8. A method of determining whether a handheld communication device (HCD) is located inside a vehicle, comprising the steps of:

(a) receiving at a central facility a request to locate the HCD;

(b) sending a message to the vehicle with an instruction to begin listening for an acoustical signal that is generated by the HCD;

(c) sending a message to the HCD with an instruction to generate the acoustical signal;

(d) determining whether the acoustical signal is detected at the vehicle; and

(e) transmitting a message to a user of the HCD indicating whether the HCD is located inside of the vehicle based on step (d).

9. The method of claim 8, further comprising the step of storing at the vehicle one or more sound files that each contain a recording of an acoustical signal for a particular smart phone.

10. The method of claim 8, further comprising the steps of receiving a smart phone identifier at the central facility and transmitting the smart phone identifier to the vehicle.

11. The method of claim 8, further comprising the steps of receiving a vehicle identifier at the central facility and transmitting the vehicle identifier to the vehicle.

12. The method of claim 8, further comprising the step of transmitting from the central facility to a second central facility an instruction for the HCD to generate an acoustical signal.

13. A method of determining whether a handheld communication device (HCD) is located inside a vehicle, comprising the steps of:

(a) receiving at the vehicle an instruction to begin listening for an acoustical signal generated by the HCD;

(b) listening for the acoustical signal at the vehicle;

(c) detecting the absence or presence of the acoustical signal generated by the HCD at the vehicle; and

(d) transmitting a message to a central facility indicating whether the vehicle detected the acoustical signal.

14. The method of claim 13, further comprising the step of storing at the vehicle one or more sound files that each contain a recording of an acoustical signal for a particular smart phone.

15. The method of claim 13, further comprising the step of receiving a smart phone identifier at the vehicle.

16. The method of claim 13, further comprising the step of receiving a vehicle identifier at the vehicle.

17. The method of claim 13, further comprising the step of transmitting from the central facility to a second central facility an instruction for the HCD to generate an acoustical signal.
