Method of determining vehicle accident, server device for performing the same, and vehicle electronic device and operation method thereof

1. A method of determining a vehicle accident, the method comprising:

receiving, from a vehicle, first information including a speed and a location of the vehicle for a communication period having variable value;

obtaining second information including environment information of a trail of the vehicle;

updating the communication period based on the first information and the second information such that a moving range of the vehicle during the communication period corresponds to a reference value;

determining whether an accident involving the vehicle has occurred based on whether updated first information is received from the vehicle for the updated communication period; and

transmitting a notification, responsive to determining an accident involving the vehicle.

2. The method of claim 1 , wherein the second information includes information about a driving environment on the trail of the vehicle.

3. The method of claim 2 , wherein the second information includes at least one of weather, presence of a shaded area, road conditions, information about occurrence of an accident, information about an accident-prone area, or information about driving conditions that correspond to the trail of the vehicle.

4. The method of claim 1 , wherein the updating of the communication period comprises updating the communication period with a value that is inversely proportional to the speed of the vehicle such that the moving range of the vehicle during the communication period corresponds to the reference value.

5. The method of claim 1 , wherein the updating of the communication period comprises:

setting an initial communication period to a value that is inversely proportional to the speed of the vehicle such that the moving range of the vehicle during the communication period corresponds to the reference value; and

setting a final communication period by applying a weight to the initial communication period based on the second information.

6. The method of claim 1 , wherein the determining of whether an accident involving the vehicle has occurred comprises, when the updated first information is not received within the updated communication period, determining that an accident involving the vehicle has occurred.

7. The method of claim 1 , further comprising, wherein transmitting the notification comprises transmitting information about the occurrence of the accident to a first responder.

8. The method of claim 1 , wherein the determining of whether an accident involving the vehicle has occurred comprises:

determining whether the updated first information is received within the updated communication period;

when the updated first information is not received within the updated communication period, requesting situation information from at least one nearby vehicle based on the first information;

receiving the situation information from at least one of the at least one nearby vehicle; and

determining, based on the situation information, whether an accident involving the vehicle has occurred.

9. The method of claim 8 , wherein the situation information includes information indicating a driving environment on a trail of the at least one nearby vehicle.

10. A server device comprising:

a communicator configured to communicate with a vehicle; and

a processor configured to execute at least one instruction to:

update, based on first information including a speed and a location of the vehicle, received from the vehicle for a communication period having variable value, and second information that is environment information regarding a trail of the vehicle, the communication period such that a moving range of the vehicle during the communication period corresponds to a reference value, and control the communicator to transmit the updated communication period to the vehicle;

determine whether an accident involving the vehicle has occurred based on whether updated first information is received from the vehicle for the updated communication period; and

transmit a notification, responsive to determining an accident involving the vehicle.

11. The server device of claim 10 , wherein the second information includes at least one of weather, information about a shaded area, road conditions, information about occurrence of an accident, information about an accident-prone area, or information about driving conditions, corresponding to the trail of the vehicle.

12. The server device of claim 10 , wherein the processor is further configured to execute the at least one instruction to update the communication period with a value that is inversely proportional to the speed of the vehicle such that the moving range that correspond to the reference value.

13. The server device of claim 10 , wherein the processor is further configured to execute the at least one instruction to:

set an initial communication period to a value that is inversely proportional to the speed of the vehicle such that the moving range of the vehicle during the communication period is maintained at a value corresponding to the reference value; and

set a final communication period by applying a weight to the initial communication period based on the second information.

14. The server device of claim 10 , wherein the processor is further configured to execute the at least one instruction to:

determine whether the updated first information is received within the updated communication period;

when the updated first information is not received within the updated communication period, request situation information from at least one nearby vehicle based on the first information;

control the communicator to receive the situation information from at least one of the at least one nearby vehicle; and

determine, based on the situation information, whether the accident involving the vehicle has occurred.

15. The server device of claim 10 , further comprising a database (DB) storing a plurality of reference values respectively corresponding to a plurality of speeds.

16. The server device of claim 10 , wherein the processor is further configured to execute the at least one instruction to calculate the communication period such that the moving range of the vehicle during the communication period corresponds to the reference value by receiving the first information and the second information and performing computation via a neural network.
