Abstract

A method for determining vehicle location via a mobile computing device includes: determining, by an application of the mobile computing device, a first signal strength corresponding to a communications component of a vehicle and a first mobile device location corresponding to the first signal strength; detecting, by the application, a signal drop event corresponding to a loss of the signal corresponding to the communications component of the vehicle; determining, by the application, in response to detecting the signal drop event, the first mobile device location corresponding to the first signal strength as the vehicle location based on the first mobile device location being the most recent location at which a recorded signal strength was at a highest level; and providing, by the application, a notification indicating the vehicle location to a user of the mobile device.

First claim

The invention claimed is:

1. A method for determining vehicle location via a mobile computing device, the method comprising:
determining, by an application of the mobile computing device, a first signal strength corresponding to a communications component of a vehicle and a first mobile device location of the mobile computing device corresponding to the first signal strength;
determining, by the application, a second signal strength corresponding to the communications component of the vehicle and a second mobile device location of the mobile computing device corresponding to the second signal strength, wherein the second mobile device location is farther away from the vehicle than the first mobile device location and the second signal strength is lower than the first signal strength;
detecting, by the application, a signal drop event corresponding to a loss of the signal corresponding to the communications component of the vehicle, wherein the signal drop event corresponds to a third mobile device location that is farther away from the vehicle than the second mobile device location;
selecting, by the application, in response to detecting the signal drop event, the first mobile device location as the vehicle location based on the first signal strength corresponding to the first mobile device location being greater than the second signal strength corresponding to the second mobile device location; and
providing, by the application, a notification indicating the vehicle location to a user of the mobile computing device.

2. The method according to claim 1 , further comprising:
determining, by the application, the third mobile device location corresponding to the signal drop event.

3. The method according to claim 1 , further comprising:
determining, by the application, that the first signal strength meets a first signal strength condition;
wherein determining the first mobile device location corresponding to the first signal strength is in response to determining that the first signal strength meets the first signal strength condition.

4. The method according to claim 3 , wherein the first signal strength condition comprises the first signal strength being within a range of signal strength values.

5. The method according to claim 1 , further comprising:
determining, by the application, that the first signal strength meets a first signal strength condition; and
determining, by the application, that the second signal strength meets a second signal strength condition;
wherein determining the first mobile device location corresponding to the first signal strength is in response to determining that the first signal strength meets the first signal strength condition; and
wherein determining the second mobile device location corresponding to the second signal strength is in response to determining that the second signal strength meets the second signal strength condition.

6. The method according to claim 5 , wherein the first signal strength condition comprises the first signal strength being within a first range of signal strength values and the second signal strength condition comprises the second signal strength being within a second range of signal strength values.

7. The method according to claim 1 , wherein determining the first mobile device location is based on satellite-positioning signals received by the mobile computing device.

8. The method according to claim 1 , wherein detecting the signal drop event corresponding to the loss of the signal corresponding to the communications component of the vehicle comprises determining that a signal strength corresponding to the communications component of the vehicle is below a signal drop threshold.

9. The method according to claim 1 , wherein the communications component of the vehicle is part of a telematics unit of the vehicle.

10. A non-transitory, computer-readable memory having processor-executable instructions stored thereon, the processor-executable instructions, when executed by a processor, being configured to carry out a method for determining vehicle location via a mobile computing device, the method comprising:
determining a first signal strength corresponding to a communications component of a vehicle and a first mobile device location of the mobile computing device corresponding to the first signal strength;
determining a second signal strength corresponding to the communications component of the vehicle and a second mobile device location of the mobile computing device corresponding to the second signal strength, wherein the second mobile device location is farther away from the vehicle than the first mobile device location and the second signal strength is lower than the first signal strength;
detecting a signal drop event corresponding to a loss of the signal corresponding to the communications component of the vehicle, wherein the signal drop event corresponds to a third mobile device location that is farther away from the vehicle than the second mobile device location;
selecting, in response to detecting the signal drop event, the first mobile device location as the vehicle location based on the first signal strength corresponding to the first mobile device location being greater than the second signal strength corresponding to the second mobile device location; and
providing a notification indicating the vehicle location to a user of the mobile computing device.

11. The non-transitory, computer-readable medium according to claim 10 , wherein the method further comprises:
determining the third mobile device location corresponding to the signal drop event.

12. The non-transitory, computer-readable medium according to claim 10 , wherein the method further comprises:
determining that the first signal strength meets a first signal strength condition;
wherein determining the first mobile device location corresponding to the first signal strength is in response to determining that the first signal strength meets the first signal strength condition.

13. The non-transitory, computer-readable medium according to claim 12 , wherein the first signal strength condition comprises the first signal strength being within a range of signal strength values.

14. The non-transitory, computer-readable medium according to claim 10 , wherein the method further comprises:
determining that the first signal strength meets a first signal strength condition; and
determining that the second signal strength meets a second signal strength condition;
wherein determining the first mobile device location corresponding to the first signal strength is in response to determining that the first signal strength meets the first signal strength condition; and
wherein determining the second mobile device location corresponding to the second signal strength is in response to determining that the second signal strength meets the second signal strength condition.

15. The non-transitory, computer-readable medium according to claim 14 , wherein the first signal strength condition comprises the first signal strength being within a first range of signal strength values and the second signal strength condition comprises the second signal strength being within a second range of signal strength values.

16. The non-transitory, computer-readable medium according to claim 10 , wherein determining the first mobile device location is based on satellite-positioning signals received by the mobile computing device.

17. The non-transitory, computer-readable medium according to claim 10 , wherein detecting the signal drop event corresponding to the los
