In detail, the infrastructure server 500, which is the load side unit, receives the message transmitted by the other vehicle 511 and transmits a radio signal to the other vehicles within a predetermined radius of the infrastructure server 500, It is possible to transmit a radio signal to the vehicle 700 after receiving the radio signal from the infrastructure server 500 and to transmit the radio signal to the infrastructure server 500 and / Receiving a radio signal from the mobile station 510 and providing the message to the user will be described below as an example.

Hereinafter, a method for acquiring a message through a plurality of communication paths according to the first embodiment will be described in detail with reference to the above-mentioned drawings and FIGS. 6 to 8. FIG.

First, the infrastructure server 500 may generate a first radio signal including a message to be transmitted to neighboring vehicles. (S101)

In the embodiment, when the other vehicle 511 entering the intersection transmits other vehicle driving information to the infrastructure server 500 in order to transmit its driving information to the vehicles located in the other intersection driving lanes, the infrastructure server 500 May generate a first radio signal including a message for other vehicle driving information.

In addition, the infrastructure server 500 may generate a first wireless signal including traffic information stored in itself in the load side unit communication device.

In addition, the infrastructure server 500 may generate a first wireless signal including privacy information when the communication relay device receives privacy information to be transmitted to the specific vehicle from the central server.

Then, the infrastructure server 500 can transmit the generated first radio signal to the neighboring vehicles. (S102)

In the embodiment, the infrastructure server 500 can transmit the first radio signal to nearby vehicles within a predetermined radius located in the outer lane surrounding the intersection where the other vehicle 511 is located.

7, the infrastructure server 500 includes the present vehicle 700 located on the vertical lane side of the lane on which the other vehicle 511 travels, and the first vehicle 500 adjacent to the present vehicle 700, It is possible to transmit the radio signal and transmit the message of the other vehicle 511. At this time, the present vehicle 700 is traveling farther away from the infrastructure server 500 than the adjacent vehicle 510, so that the communication sensitivity may be lower than that of the adjacent vehicle 510.

Next, the present vehicle 700 and the adjacent vehicle 510 can receive the first wireless signal from the infrastructure server 500. [ (S103a, S103b)

 Then, the vehicle communication device 100 can measure the communication sensitivity with the infrastructure server 500. (S104)

More specifically, the vehicle communication apparatus 100 measures the communication sensitivity with the infrastructure server 500 before or after receiving the first wireless signal, and determines whether the second wireless signal is to be received redundantly from the adjacent vehicle 510 .

For example, when the communication sensitivity with the infrastructure server 500 is equal to or less than the preset value, the vehicle communication apparatus 100 can not trust the received first radio signal data and prepare for communication with the adjacent vehicle 510 .

On the other hand, when the communication sensitivity with the infrastructure server 500 exceeds the preset value, the vehicle communication apparatus 100 can trust the data of the received first wireless signal, The message can only be restored with a signal.

In another aspect, the vehicle communication apparatus 100 measures an error rate of a first wireless signal received from the infrastructure server 500, and when the measured error rate exceeds a predetermined value, Since it is not reliable, communication with the adjacent vehicle 510 can be prepared.

Conversely, when the error rate of the first radio signal received from the infrastructure server 500 is equal to or less than a predetermined value, the vehicle communication apparatus 100 restores the message using only the first radio signal received from the infrastructure server 500 .

When the communication sensitivity is poor, the vehicle communication apparatus 100 can search for the adjacent vehicle 510 to communicate within a predetermined radius. (S105)

More specifically, the vehicle communication apparatus 100 can detect the adjacent vehicle 510 having good communication sensitivity by measuring the sensitivity of wireless communication with the adjacent vehicle 510 located nearby via the communication unit.

Further, the vehicle communication apparatus 100 may directly detect the adjacent vehicle 510 within a predetermined distance forward through the sensor unit.

When the adjacent vehicle 510 is detected, the vehicle communication apparatus 100 may request the neighboring vehicle 510 to transmit the same information as the first wireless signal received from the infrastructure server 500 through the communication unit. (S106a)

The adjacent vehicle 510 can transmit the same second radio signal as the first radio signal received from the infrastructure server 500 to the vehicle communication device 100. [ (S106b)

Thereafter, the vehicle communication apparatus 100 can receive the same message through the first wireless signal and the second wireless signal by receiving the second wireless signal of the information requested from the adjacent vehicle. (S107)

The vehicle communication apparatus 100 receiving the first radio signal and the second radio signal can recover the message based on one of the two radio signals.

More specifically, in the embodiment, the vehicle communication apparatus 100 can detect the error block of the first wireless signal received from the infrastructure server 500 first. (S108)

Then, the vehicle communication apparatus 100 can correct the error block of the first radio signal with the data of the second radio signal. (S109)

More specifically, when the vehicle communication apparatus 100 detects an error block in the data of the first wireless signal, it extracts a data block corresponding to the error block of the first wireless signal from the data of the second wireless signal, The error block of the first wireless signal can be corrected with the data block of the wireless signal.

8, the first data M1 of the radio signal transmitted from the other vehicle 511 and the infrastructure server 500 does not include an error block and the first data M1 transmitted from the infrastructure server 500 The first data signal M2 of the first radio signal has an error in the first data block and the second data block and the third data M3 of the second radio signal received from the adjacent vehicle 510 has an error in the fourth data block It can be seen that it occurred.

Since an error has occurred in the first and second data blocks of the first wireless signal, the vehicle communication apparatus 100 extracts the first and second data blocks of the matching second wireless signal and overwrites the data of the first wireless signal , The first wireless signal can be corrected.

Finally, the vehicle communication apparatus 100 can recover the data of the corrected first radio signal to acquire the message. (S110) and the vehicle communication apparatus 100 can provide the obtained message to the user through the display unit, the audio output unit, and the like.

That is, when the communication with the infrastructure server 500 is not smooth, the vehicle communication apparatus 100 communicates with the adjacent vehicle 510 to receive radio signals redundantly, corrects errors of the received radio signals, The message can be correctly received. Furthermore, even if there is a data error in each of the radio signals received from the infrastructure server 500 and the adjacent vehicle 510, the complete message can be obtained by correcting it with complete data.

The vehicle communication apparatus 100 can provide a user with a necessary message precisely at the right time, thereby inducing safe driving between vehicles, traveling at optimal traffic efficiency, and improving user convenience.

Hereinafter, a method of acquiring a message through a plurality of communication paths according to the second embodiment will be described in detail with reference to the above-described drawings and FIGS. 9 to 10. FIG.

First, the infrastructure server 500 may generate a first radio signal for a message to be transmitted to neighboring vehicles. (S201)

In the embodiment, when the other vehicle 511 entering the intersection transmits other vehicle driving information to the infrastructure server 500 in order to transmit its driving information to the vehicles located in the other intersection driving lanes, the infrastructure server 500 May generate a first radio signal including a message for other vehicle driving information.

In addition, the infrastructure server 500 may generate a first wireless signal including traffic information by itself in the load side unit communication device.

In addition, the infrastructure server 500 may generate a first wireless signal including privacy information when the communication relay device receives privacy information to be transmitted to the specific vehicle from the central server.

Then, the infrastructure server 500 can transmit the generated first radio signal to the neighboring vehicles. (S202)

The infrastructure server 500 can transmit the first radio signal to the adjacent vehicles 510 within a predetermined radius located at the outer lane surrounding the intersection where the other vehicle 511 is located, Signal can be received. (S203)

In the embodiment, the vehicle communication apparatus 100 may be in a state in which the first radio signal is not received or received even if it is outside the predetermined radius of the infrastructure server 500 or the communication sensitivity is not good, have.

At this time, the vehicle 700 is traveling from behind the adjacent vehicle 510, and the communication sensitivity of the infrastructure server 500 is low, so that the first vehicle can not receive the first wireless signal.

Next, the adjacent vehicle 510 can transmit the second radio signal, which is the same as the message of the first radio signal, from the infrastructure server 500 to the vehicle communication apparatus 100 of the present vehicle 700. (S204)

That is, the adjacent vehicle 510 may send a second wireless signal to the rear vehicle to assist the infrastructure server 500 to quickly receive messages from the rear vehicle outside the communication radius.

Next, the vehicle communication apparatus 100 can receive the second radio signal from the adjacent vehicle 510. [ (S206)

For example, when the communication sensitivity with the adjacent vehicle 510 is equal to or less than the predetermined value, the vehicle communication apparatus 100 can not trust the received second wireless signal data. Therefore, the vehicle communication apparatus 100 may prepare for communication with the infrastructure server 500 .

Conversely, when the communication sensitivity with the adjacent vehicle 510 exceeds the preset value, the vehicle communication apparatus 100 can reliably receive the data of the received second radio signal, and thus the message is restored only by the second radio signal , Power consumption and communication efficiency can be improved.

The vehicle communication apparatus 100 measures the error rate of the second radio signal received from the adjacent vehicle 510 and outputs the data of the received second radio signal when the measured error rate exceeds a predetermined value Since it is not reliable, it can prepare for communication with the infrastructure server 500.

Conversely, when the error rate of the second radio signal is equal to or smaller than the predetermined value, the vehicle communication apparatus 100 can restore the message using only the second radio signal, thereby improving power consumption and communication efficiency.

When the communication sensitivity is poor, the vehicle communication apparatus 100 may request the infrastructure server 500 to transmit a radio signal and receive a first radio signal of the same message as the second radio signal from the infrastructure server 500 have. (S207, S208, S209)

That is, when the vehicle 700 travels within the communication radius of the infrastructure server 500, the vehicle communication apparatus 100 transmits the first wireless signal transmitted by the infrastructure server 500 to the second wireless signal, .

The vehicle communication apparatus 100 receiving the first radio signal and the second radio signal can recover the message based on one of the two radio signals.

More specifically, in the embodiment, the vehicle communication apparatus 100 can detect an error block of the second wireless signal received from the adjacent vehicle 510. [ (S210)

Then, the vehicle communication apparatus 100 can correct the error block of the second wireless signal with the data of the first wireless signal. (S211)

More specifically, when the vehicle communication apparatus 100 detects an error block in the data of the second wireless signal, it extracts a data block corresponding to the error block of the second wireless signal from the data of the first wireless signal, The error block of the second wireless signal can be corrected with the data block of the wireless signal.

10, the first data M1 of the radio signals transmitted by the other vehicle 511 and the infrastructure server 500 are free of error blocks and the third data of the second radio signal received from the adjacent vehicle 510 The data M3 has an error in the fourth data block and the first wireless signal second data M2 received from the infrastructure server 500 by the vehicle communication apparatus 100 has an error in the first data block and the second data block It can be seen that it occurred.
