Method and device for data sharing using MEC server in autonomous driving system
A method for sharing data using a mobile edge computing (MEC) server in an autonomous driving system includes receiving a first controller area network (CAN) message from a first vehicle, generating a V2X message including information of the first CAN message when autonomous vehicle information is registered in the MEC server, and transmitting the V2X message to an autonomous vehicle connected to the MEC server via broadcast. This allows data to be shared between vehicles using different data types. At least one of an autonomous vehicle, a user terminal, and a server of the present disclosure may be associated with an artificial intelligence module, a drone (Unmannered Aerial Vehicle, UAV) robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to a 5G service, and the like.
1. A method for sharing data using a mobile edge computing (MEC) server in an autonomous driving system, the method comprising:
receiving a first controller area network (CAN) message from a first vehicle;
generating a vehicle-to-everything (V2X) message including information of the first CAN message, based on autonomous vehicle information being registered in the MEC server;
transmitting, via broadcast, the V2X message to an autonomous vehicle connected to the MEC server;
generating a second CAN message including the information of the first CAN message, based on vendor information of a vendor other than a vendor of the first vehicle being registered in the MEC server; and
transmitting, via the broadcast, the second CAN message to a second vehicle associated with the vendor information,
wherein the second CAN message is associated with the vendor information.
2. The method of claim 1 , further comprising:
receiving the vendor information of the second vehicle from the second vehicle; and
registering the vendor information of the second vehicle.
3. The method of claim 1 , further comprising:
receiving the autonomous vehicle information from the autonomous vehicle; and
registering the autonomous vehicle information.
4. The method of claim 1 , wherein the V2X message includes a value of a time at which the first CAN message is received.
5. The method of claim 4 , wherein the autonomous vehicle corrects position information included in the V2X message based on the value of the time at which the first CAN message is received.
6. The method of claim 1 , wherein the second CAN message includes a value of a time at which the first CAN message is received.
7. The method of claim 6 , wherein the second vehicle corrects position information included in the second CAN message based on the value of the time at which the first CAN message is received.
8. A method for sharing data using a mobile edge computing (MEC) server in an autonomous driving system, the method comprising:
receiving a vehicle-to-everything (V2X) message from an autonomous vehicle;
receiving, from a first vehicle, vendor information of the first vehicle;
registering the vendor information of the first vehicle;
generating a controller area network (CAN) message including information of the V2X message, based on the vendor information of the first vehicle being registered in the MEC server; and
transmitting, via broadcast, the CAN message to the first vehicle connected to the MEC server.
9. The method of claim 8 , wherein the CAN message includes a value of a time at which the V2X message is generated.
10. The method of claim 9 , wherein the first vehicle corrects a position of the autonomous vehicle based on the value of the time at which the V2X message is generated.
11. A mobile edge computing (MEC) server configured to share data in an autonomous driving system, the MEC server comprising:
a transceiver;
a memory; and
a processor,
wherein the processor is configured to:
receive a first controller area network (CAN) message from a first vehicle via the transceiver;
generate a vehicle-to-everything (V2X) message including information of the first CAN message, based on autonomous vehicle information being registered in the memory;
transmit, via broadcast via the transceiver, the V2X message to an autonomous vehicle connected to the MEC server;
generate a second CAN message including the information of the first CAN message, based on vendor information of a vendor other than a vendor of the first vehicle being registered in the MEC server; and
transmit, via the broadcast via the transceiver, the second CAN message to a second vehicle associated with the vendor information,
wherein the second CAN message is associated with the vendor information.
12. The MEC server of claim 11 , wherein the processor is configured to:
receive the vendor information of the second vehicle from the second vehicle via the transceiver; and
register the vendor information of the second vehicle in the memory.
13. The MEC server of claim 11 , wherein the processor is configured to:
receive the autonomous vehicle information from the autonomous vehicle via the transceiver; and
register the autonomous vehicle information in the memory.
14. The MEC server of claim 11 , wherein the V2X message includes a value of a time at which the first CAN message is received.
15. The MEC server of claim 14 , wherein the autonomous vehicle corrects position information included in the V2X message based on the value of the time at which the first CAN message is received.
16. The MEC server of claim 11 , wherein the second CAN message includes a value of a time at which the first CAN message is received.
17. The MEC server of claim 16 , wherein the second vehicle corrects position information included in the second CAN message based on the value of the time at which the first CAN message is received.
