seeking a connection on the cellular network with the drone in response to the telematics unit being unable to connect to the cellular network; and

transmitting from the drone via the cellular network one or more of the current location of the system, a picture of a scene around the system taken by the drone hovering above the current location, and the initial time of the trigger event in response to the connection being established by the drone.

4. The method according to claim 3 , further comprising:

releasing the drone from the tether in response to the drone being unable to connect to the cellular network;

increasing a height of the drone; and

re-seeking the connection on the cellular network.

5. The method according to claim 3 , further comprising:

determining a calculated direction to find the assistance with the telematics unit based on one or more maps of a plurality of cellular towers proximate the current location and a plurality of towns proximate the current location;

transferring the calculated direction to the drone;

releasing the drone from the tether; and

flying the drone in the calculated direction.

6. The method according to claim 5 , further comprising:

seeking a connection on the cellular network with the drone while flying an approximately straight path in the calculated direction; and

transmitting from the drone via the cellular network one or more of the current location of the system, a picture of a scene around the system taken by the drone hovering above the current location, and an initial time of the trigger event in response to the connection being established by the drone.

7. The method according to claim 5 , further comprising:

flying the drone along a road running in approximately the calculated direction;

seeking an assistance vehicle on the road with the drone; and

displaying one or more of a visual notification and an audio notification from the drone to the assistance vehicle in response to the drone finding the assistance vehicle.

8. The method according to claim 7 , further comprising:

receiving at the drone an acknowledgement from the assistance vehicle that at least one of the visual notification and the audio notification was received; and

flying the drone along the road back to the current location in response to the acknowledgement.

9. The method according to claim 2 , further comprising:

requesting an assistance via a cellular network with the telematics unit in response to the deploying of the drone;

limiting a horizontal range of the drone from the system with the tether; and

releasing the drone from the tether in response to the initial location being further than the horizontal range and the telematics unit being unable to connect to the cellular network.

10. The method according to claim 1 , further comprising:

receiving a manual direction from a user control;

transferring the manual direction to the drone; and

flying the drone in the manual direction.

11. The method according to claim 1 , further comprising:

measuring an acceleration of the system; and

asserting the trigger event in response to the acceleration exceeding a threshold acceleration value.

12. The method according to claim 1 , further comprising:

measuring a roll-over index of the system; and

asserting the trigger event in response to the roll-over index exceeding a threshold index value.

13. The method according to claim 1 , further comprising:

monitoring a plurality of brakes of the system; and

asserting the trigger event in response to one or more of the plurality of brakes indicating a slippage.

14. The method according to claim 1 , further comprising:

measuring a temperature of a battery;

asserting the trigger event in response to the temperature exceeding a threshold temperature value; and

asserting the subsequent event in response to the temperature indicating a thermal runaway condition in the battery.

15. The method according to claim 1 , further comprising:

asserting the trigger event in response to a theft alarm being triggered; and

asserting the subsequent event in response to the theft alarm remaining triggered during the predetermined time.

16. A system comprising:

a drone having one or more notification actuators, wherein the one or more notification actuators includes one or more of a speaker and a light;

a storage member configured to carry, deploy, and recover the drone;

one or more electronic units configured to detect a trigger event and a subsequent event in the system; and

a telematics unit in communication with the one or more electronic units and the drone, the telematics unit being configured to:

launch the drone configuration in response to the trigger event;

wait a predetermined time after the trigger event;

retract the drone into the storage member in response to the subsequent event being undetected within the predetermined time after the trigger event;

command the storage member to secure the drone after the drone is retracted into the storage member; and

place the drone in an alert configuration in response to detecting the subsequent event within the predetermined time after the trigger event;

wherein the drone is configured to generate one or more alert notifications from the one or more notification actuators while the drone is in the alert configuration, and the one or more alert notifications include one or more of an audio notification and a visual notification.

17. The system according to claim 16 , wherein the one or more electronic units includes a stability control unit, an anti-lock braking system, a battery temperature monitor, a theft alarm, an airbag controller, and a supplemental restraint system.
