Drone-based vehicle connectivity systems and methods

1. A method comprising:

determining, by a vehicle and/or a drone associated with the vehicle, that a triggering event has occurred, the triggering event including a loss of network connectivity of the vehicle and an emergency situation involving the vehicle and/or an occupant of the vehicle, the loss of connectivity including damage to a first antenna of the vehicle, the emergency situation including at least one of a health emergency of the occupant and a disablement of the vehicle, and the disablement of the vehicle associated with an accident involving the vehicle, a mechanical failure of the vehicle, or a loss of fuel of the vehicle;

creating, by the vehicle and/or the drone and based on the triggering event occurring, an emergency message indicative of the emergency situation;

automatically and autonomously launching, based on the triggering event occurring, the drone to navigate to a location where network connectivity exists and creating a network bridge for the vehicle, wherein the drone maintains a network bridge until emergency services arrive at a location of the vehicle;

transmitting, when a connection to a network is established by the drone, the emergency message to a service provider; and

determining network connectivity of the drone with another vehicle and transmitting the emergency message by the drone to the another vehicle, the another vehicle being a ground vehicle configured to relay the emergency message to one or more additional vehicles or to the service provider.

2. The method according to claim 1 , further comprising identifying, with a telematic control unit of the vehicle, the location where network connectivity exists by tracking cellular connection data of the vehicle as the vehicle is driven or searching a coverage map stored in memory on the drone.

3. The method according to claim 2 , wherein tracking the cellular connection data includes identifying network connection spots by location and signal strength.

4. The method according to claim 1 , further comprising selectively adjusting a directionality of a second antenna of the drone to maximize a signal strength of the connection to the network.

5. The method according to claim 1 , further comprising obtaining an image of the vehicle by the drone and transmitting the image along with the emergency message to the service provider.

6. The method according to claim 5 , further comprising obtaining vehicle information associated with the vehicle by the drone and transmitting the vehicle information along with the emergency message to the service provider.

7. The method according to claim 1 , wherein said drone is automatically and autonomously launched from a compartment of said vehicle.

8. A drone comprising:

a communications module;

a processor; and

a memory for storing instructions, the processor executing the instructions to:

determine an occurrence of a triggering event, the triggering event including a loss of network connectivity by a vehicle and/or the drone and an emergency situation involving the vehicle and/or a user of the vehicle, the emergency situation including at least one of a health emergency of the user and a disablement of the vehicle, and the disablement of the vehicle associated with an accident involving the vehicle, a mechanical failure of the vehicle, or a loss of fuel of the vehicle;

receive vehicle information from the vehicle, the vehicle information comprising any one or more of text, audio, and/or video;

generate an emergency message indicative of the emergency situation, the emergency message comprising the vehicle information and a vehicle location;

autonomously launch and navigate, by the drone, to a location where network connectivity exists and creating a network bridge for the vehicle, wherein the drone maintains a network bridge until emergency services arrive at a location of the vehicle;

transmit, by the drone, the emergency message to a service provider when the communications module establishes a connection to a network; and

determine network connectivity of the drone with another vehicle and transmit the emergency message to the another vehicle, the another vehicle being a ground vehicle configured to relay the emergency message to one or more additional vehicles or to the service provider.

9. The drone according to claim 8 , wherein the processor is configured to:

establish a network bridge between a vehicle communications module of the vehicle and a base station of the network; and

selectively adjust a directionality of an antenna to maximize a signal strength of the connection or utilize a plurality of antennas.

10. The drone according to claim 8 , wherein the processor is configured to:

obtain an image of the vehicle and vehicle information associated with the vehicle; and

transmit the image and the vehicle information along with the emergency message to the service provider.

11. A method comprising:

determining that a triggering event has occurred, the triggering event including a loss of network connectivity of a communications module of a vehicle and an occurrence of an emergency situation involving the vehicle and/or a user of the vehicle, the loss of connectivity including damage to an antenna of the vehicle, the emergency situation including at least one of a health emergency of the user and a disablement of the vehicle, and the disablement of the vehicle associated with an accident involving the vehicle, a mechanical failure of the vehicle, or a loss of fuel of the vehicle;

receiving user input through a human machine interface (HMI) of the vehicle, the user input comprising any one or more of text, audio, and/or video;

generating an emergency message indicative of the emergency situation, the emergency message comprising the user input in combination with vehicle information and vehicle location;

automatically and autonomously launching, based on the triggering event occurring, a drone to establish connectivity with a network, the drone navigating to a location where connectivity with the network is available and creating a network bridge for the vehicle, wherein the drone maintains a network bridge until emergency services arrive at a location of the vehicle;

transmitting, by the drone, the emergency message to a service provider; and

determining network connectivity of the drone with another vehicle and transmitting the emergency message by the drone to the another vehicle, the another vehicle being a ground vehicle configured to relay the emergency message to one or more additional vehicles or to the service provider.

12. The method according to claim 11 , further comprising tracking, with a telematic control unit of the vehicle, cellular connection data of the vehicle as the vehicle is driven and identifying network connection spots by location and signal strength.

13. The method according to claim 11 , further comprising transmitting controller area network data of the vehicle to the drone for forwarding to the service provider.

14. The method of claim 11 , further comprising automatically launching the drone based on receiving a second user input to the HMI.

15. The method according to claim 11 , wherein said drone is automatically and autonomously launched from a compartment of said vehicle.
