Abstract

A method of providing an alert that a portable electronic device has been left at a vehicle. The method comprises determining that an occupant has exited the vehicle. The method further comprises detecting that a portable electronic device is located at the vehicle. When it has been determined that the occupant has left the vehicle and that the electronic device has been left behind, the method still further comprises generating an alert to notify the occupant that the electronic device has been left at the vehicle. A system for performing or utilizing the above-described methodology is also provided.

Claims

1. A method of providing an alert that a portable electronic device configured to be wirelessly connected to a device of the vehicle has been left at a vehicle, comprising the steps of:

(a) determining that an occupant has exited the vehicle;

(b) acquiring a measurement of the signal strength of a wireless connection between the portable electronic device and the vehicle device and detecting that the portable electronic device is located at the vehicle based at least in part on the acquired signal strength measurement; and

(c) generating an alert to notify the occupant that the electronic device has been left at the vehicle.

2. The method of claim 1, wherein step (a) comprises determining that the occupant has left the vehicle in response to the occurrence of a predetermined event.

3. The method of claim 2, wherein the predetermined event comprises at least one of:

the vehicle being turned off;

the vehicle doors being locked;

the vehicle being turned off and a predetermined amount of time having elapsed without the vehicle being re-started or the occupant re-entering the vehicle; and

a smart key for the vehicle being removed from the vehicle.

4. The method of claim 1, wherein the acquired signal strength measurement is a first acquired signal strength measurement

corresponding to a time at which a predetermined event occurs, and step (b) further comprises

acquiring a second measurement of the signal strength of the wireless connection corresponding to a time subsequent to the time corresponding to the first measurement;

comparing the first and second measurements and determining whether the electronic device is located at the vehicle based on the comparison.

5. The method of claim 4, wherein the second measurement corresponds to a time that is at least one of:

a time that is a predetermined amount of time subsequent to the occurrence of the predetermined event; and

a time at which another predetermined event occurs.

6. The method of claim 4, wherein the predetermined event comprises the turning off of the vehicle and the second measurement corresponds to a time that is at least one of

a time that is a predetermined amount of time subsequent to the vehicle being turned off;

a time at which the vehicle is locked; and

a time at which a smart key for the vehicle is removed from the vehicle.

7. The method of claim 1, wherein step (b) comprises

detecting that the electronic device is located at the vehicle when the signal strength measurement is greater than a predetermined minimum signal strength.

8. The method of claim 1, wherein step (c) comprises generating at least one of:

an auditory alert indicative of the electronic device being left at the vehicle;

a visual alert indicative of the electronic device being left at the vehicle; and

a message indicative of the electronic device being left at the vehicle.

9. A method of providing an alert that a portable electronic device has been left at a vehicle, comprising the steps of:

(a) determining that an occupant has exited the vehicle;

(b) detecting that a portable electronic device is electrically connected to an electromechanical port disposed within the vehicle and thus that the portable electronic device is located at the vehicle; and

(c) generating an alert to notify the occupant that the electronic device has been left at the vehicle.

10. A system for providing an alert that a portable electronic device configured to be wirelessly connected to a device of the vehicle has been left at a vehicle, comprising an electronic processing device configured to:

(a) determine that an occupant has exited the vehicle;

(b) acquire a measurement of the signal strength of a wireless connection between the portable electronic device and the vehicle device and to detect that the portable electronic device is located at the vehicle based at least in part on the acquired signal strength measurement; and

(c) generate an alert to notify the occupant that the electronic device has been left at the vehicle.

11. The system of claim 10, wherein the electronic processing device is configured to determine that an occupant has exited the vehicle in response to the occurrence of a predetermined event.

12. The system of claim 11, wherein the predetermined event comprises at least one of:

the vehicle being turned off;

the vehicle doors being locked;

the vehicle being turned off and a predetermined amount of time having elapsed without the vehicle being re-started or the occupant re-entering the vehicle; and

a smart key for the vehicle being removed from the vehicle.

13. The system of claim 10, wherein the acquired signal strength measurement is a first acquired signal strength measurement

corresponding to a time at which a predetermined event occurs, and the electronic processing device is further configured to:

acquire a second measurement of the signal strength of the wireless connection between the electronic device and the vehicle device corresponding to a time subsequent to the time corresponding to the first measurement;

compare the first and second measurements; and

determine whether the electronic device is located at the vehicle based on the comparison of the first and second measurements.

14. The system of claim 13, wherein the vehicle device comprises the electronic processing device.

15. The system of claim 13, wherein the second measurement corresponds to a time that is at least one:

a time that is a predetermined amount of time subsequent to the occurrence of the predetermined event; and

a time at which another predetermined event occurs.

16. The system of claim 13, wherein the predetermined event comprises the turning off of the vehicle and the second measurement corresponds to a time that is at least one of:

a time that is a predetermined amount of time subsequent to the vehicle being turned off;

a time at which the vehicle is locked; and

a time at which a smart key for the vehicle is removed from the vehicle.

17. The system of claim 10, wherein the electronic processing device is configured to

detect that the electronic device is located at the vehicle when the signal strength measurement is greater than a predetermined minimum signal strength.

18. The system of claim 17, wherein the vehicle device comprises the electronic processing device.

19. The system of claim 10, wherein the electronic processing device is configured to generate an alert by at least one of:

generating an auditory alert indicative of the electronic being left at the vehicle;

generating a visual alert indicative of the electronic device being left at the vehicle; and

generating a message indicative of the electronic device being left at the vehicle.

20. A system for providing an alert that a portable electronic device has been left at a vehicle, comprising an electronic processing device configured to:

(a) determine that an occupant has exited the vehicle;

(b) detect that a portable electronic device is located at the vehicle by detecting that the electronic device is electrically connected to an electromechanical port disposed within the vehicle; and

(c) generate an alert to notify the occupant that the electronic device has been left at the vehicle.
