Abstract

A vehicle system includes a communication device programmed to pair with a mobile device and a processing device programmed to periodically transmit, to the mobile device, a present location signal representing a present location of the mobile device. The processing device is further programmed to detect a vehicle shutdown and transmit a final location signal to the mobile device, the final location signal representing a final location of the mobile device and a shutdown flag.

Claims

1. A vehicle system comprising:

a communication device programmed to pair with a mobile device; and

a processing device programmed to periodically transmit, to the mobile device, a present location signal representing a present location of the mobile device,

wherein the processing device is programmed to detect a vehicle shutdown and transmit a final location signal to the mobile device, the final location signal representing a final location of the mobile device and a shutdown flag.

2. The vehicle system of claim 1, wherein the shutdown flag indicates that a host vehicle is powering down.

3. The vehicle system of claim 1, wherein the processing device is programmed to detect the present location and the final location of the mobile device in the vehicle.

4. The vehicle system of claim 3, wherein the processing device is programmed to detect the present location and the final location of the mobile device based at least in part on a signal strength indicator.

5. The vehicle system of claim 4, wherein the signal strength indicator is based on a signal strength of a signal transmitted from the mobile device and received by the communication device.

6. The vehicle system of claim 1, wherein the mobile device is programmed to transmit the final location and the shutdown flag to a wearable device.

7. The vehicle system of claim 1, wherein the mobile device is programmed to transmit battery information to a wearable device.

8. The vehicle system of claim 1, wherein the communication device is programmed to transmit the final location of the mobile device and the shutdown flag to a wearable device.

9. The vehicle system of claim 1, wherein the communication device is programmed to receive battery information from the mobile device and transmit the battery information to a wearable device.

10. A method comprising:

pairing a wearable device to a mobile device;

receiving, via the wearable device, location information representing a location of the mobile device relative to a host vehicle;

determining whether the mobile device is still paired with wearable device;

generating, via the wearable device, an alert if the mobile device is no longer paired with the wearable device; and

displaying, via the wearable device, the location of the mobile device relative to the host vehicle in response to the generating the alert.

11. The method of claim 10, further comprising determining whether the mobile device is still paired with the wearable device based at least in part on a signal strength of a signal transmitted from the mobile device.

12. The method of claim 10, further comprising determining whether a distance between the mobile device and the wearable device is increasing based at least in part on a change in signal strength of a signal transmitted from the mobile device.

13. The method of claim 12, further comprising determining that the distance is increasing if the signal strength decreases.

14. The method of claim 12, further comprising:

receiving, via the wearable device, battery information associated with the mobile device; and

determining that the distance is increasing if the battery information indicates that a battery of the mobile device is charged above a predetermined level.

15. A non-transitory computer readable medium storing a software program, the software program being executable by a processor of a computing device to provide operations comprising:

pairing a wearable device to a mobile device;

receiving, via the wearable device, location information representing a location of the mobile device relative to a host vehicle;

determining whether the mobile device is still paired with wearable device;

generating, via the wearable device, an alert if the mobile device is no longer paired with the wearable device; and

displaying, via the wearable device, the location of the mobile device relative to the host vehicle in response to the generating the alert.

16. The computer-readable medium of claim 15, the operations further comprising determining whether the mobile device is still paired with the wearable device based at least in part on a signal strength of a signal transmitted from the mobile device.

17. The computer-readable medium of claim 15, the operations further comprising determining whether a distance between the mobile device and the wearable device is increasing based at least in part on a change in signal strength of a signal transmitted from the mobile device.

18. The computer-readable medium of claim 17, the operations further comprising determining that the distance is increasing if the signal strength decreases.

19. The computer-readable medium of claim 17, the operations further comprising:

receiving, via the wearable device, battery information associated with the mobile device; and

determining that the distance is increasing if the battery information indicates that a battery of the mobile device is charged above a predetermined level.
