Vehicle having vehicle control device and vehicle control method
The present disclosure relates to a vehicle having a communication device configured to communicate with an external server through a plurality of channels, and a vehicle control device configured to control the communication device to receive a safety-related message from the external server. The plurality of channels includes a first channel that is allocated to transmit and receive the safety-related message, and the vehicle control device is configured to control the communication device to receive the safety-related message from the external server through a second channel that is different from the first channel.
1. A vehicle comprising:
a communication device configured to communicate with an external server through a plurality of channels; and
a vehicle control device configured to control the communication device to receive a safety-related message from the external server,
wherein the plurality of channels includes a first channel that is allocated to transmit and receive the safety-related message,
wherein the vehicle control device is configured to control the communication device to receive the safety-related message from the external server through a second channel that is different from the first channel,
wherein the second channel is allocated to transmit and receive a service message,
wherein the vehicle control device is configured to receive the safety-related message from the external server through the second channel rather than the first channel based on a predetermined condition being satisfied while the communication device is set to the second channel, and
wherein the vehicle control device is configured to control the communication device to transmit a request message for requesting the safety-related message from the external server through the second channel based on the predetermined condition being satisfied while the communication device is set to the second channel.
2. The vehicle of claim 1 , wherein:
the external server receives at least one safety-related message from one or more vehicles present in a predetermined region; and
the vehicle control device is configured to receive a safety-related message corresponding to the request message among safety-related messages received from the external server through the second channel.
3. The vehicle of claim 2 , wherein:
the request message includes information for requesting a first message related to safety of one or more vehicles in which a predetermined event has occurred; and
based on the one or more vehicles in which the predetermined event has occurred being present in the predetermined region, the vehicle control device receives the first message from the external server through the second channel.
4. The vehicle of claim 3 , wherein the predetermined event includes being in an accident, breaking down, or being an emergency vehicle.
5. The vehicle of claim 2 , wherein based on the request message including information for requesting a second message related to safety of a third-party vehicle present within a certain distance from the vehicle, the vehicle control device receives the second message from the external server through the second channel.
6. The vehicle of claim 5 , wherein the vehicle control device is configured, based on receiving the safety-related message from the third-party vehicle, to determine at least one of a relative location, a relative speed, or a relative angle of the third-party vehicle.
7. The vehicle of claim 6 , wherein the vehicle control device is configured, based on receiving the safety-related message from the third-party vehicle, to perform an advanced driving assistance system (ADAS) function.
8. The vehicle of claim 1 , wherein the communication device is configured to communicate with the external server via a road side unit (RSU) installed on a road.
9. The vehicle of claim 8 , wherein:
the external server receives a safety-related message from one or more vehicles present in a predetermined region via the RSU; and
the vehicle control device is configured to receive a safety-related message from the external server via the RSU.
10. The vehicle of claim 1 , wherein based on a third-party vehicle that performs communication through a plurality of channels at one time point being identified, the vehicle control device controls the communication device to receive the safety-related message from the third-party vehicle.
11. The vehicle of claim 1 , wherein the communication device is a radio receiver.
12. The vehicle of claim 1 , wherein the first channel is allocated to a first radio frequency, and the second channel is allocated to a second radio frequency that is different from the first radio frequency.
13. The vehicle of claim 1 , wherein the predetermined condition includes a user request.
14. The vehicle of claim 1 , wherein the predetermined condition includes a number of the safety-related messages transmitted to or received from the external server being higher than a reference value.
15. The vehicle of claim 1 , wherein the safety-related message is formed according to a dedicated short-range communication (DSRC) communication standard.
16. A vehicle control method comprising:
communicating with an external server through any one of a plurality of channels; and
receiving a safety-related message from the external server,
wherein the receiving comprises receiving the safety-related message from the external server through a channel other than a channel allocated to transmit and receive the safety-related message,
wherein the plurality of channels includes a first channel that is allocated to transmit and receive the safety-related message, and
wherein the vehicle control method further comprises:
controlling a communication device to receive the safety-related message from the external server through a second channel that is different from the first channel, the second channel is allocated to transmit and receive a service message,
receiving the safety-related message from the external server through the second channel rather than the first channel based on a predetermined condition being satisfied while the communication device is set to the second channel, and
transmitting a request message for requesting the safety-related message from the external server through the second channel based on the predetermined condition being satisfied while the communication device is set to the second channel.
17. The control method of claim 16 , further comprising receiving at the external server at least one safety-related message from a third-party vehicle present in a predetermined region.
18. The control method of claim 17 , further comprising determining, based on receiving the safety-related message from the third-party vehicle, at least one of a relative location, a relative speed, or a relative angle of the third-party vehicle.
