Referring to FIG. 3, a first vehicle 100 according to an embodiment includes a communication unit 200 capable of communicating with a base station ST; An output unit 400 for outputting traffic information received from the base station ST; A control unit 300 for controlling the communication unit 200 and the output unit 400; . ≪ / RTI >

The communication unit 200 may employ various communication methods to communicate with the base station ST. For example, the communication unit 200 can transmit and receive a wireless signal to and from a base station ST through a communication method such as 3G (3G) or 4G (4Generation), and wireless LAN, Wi- ), Bluetooth, Zigbee, Wi-Fi Direct, Ultra Wideband, Infrared Data Association (BDA), Bluetooth Low Energy (BLE), Near Field Communication And may transmit and receive information with the base station ST within a predetermined distance through the same communication method.

Also, the communication unit 200 can transmit and receive a radio signal through a 5G (5 Generation) communication method. Hereinafter, the 5G communication method will be described in detail with reference to FIG.

FIG. 4 is a diagram illustrating a large-scale antenna system of a base station according to a 5G communication scheme according to an embodiment.

The 5G communication method uses the frequency band of 2 GHz or less, but the 5G communication method can use the ultra high frequency band of about 28 GHz band. However, the frequency band used by the 5G communication system is not limited thereto.

A large-scale antenna system may be employed for the 5G communication system. A large-scale antenna system means a system that can cover up to a very high frequency using dozens or more antennas, and can transmit / receive a large amount of information at the same time through multiple accesses. Specifically, the large-scale antenna system can adjust the arrangement of the antenna elements to transmit and receive radio waves farther in a specific direction, thereby enabling a large-capacity transmission and expanding the usable area of the 5G communication network.

Referring to FIG. 4, a base station can simultaneously transmit and receive information with many devices through a large-scale antenna system. In addition, the large-scale antenna system minimizes radio waves radiated in a direction outside the direction of propagation of radio waves to reduce noise, thereby improving transmission quality and reducing the amount of electric power.

In addition, the 5G communication method uses a non-orthogonal multiplexing access (NOMA) method to modulate a radio signal, unlike a conventional method of modulating a transmission signal through an Orthogonal Frequency Division Multiplexing By this transmission, more devices can be connected to multiple devices, and large capacity transmission / reception is possible at the same time.

In addition, the 5G communication method enables real-time processing with a maximum response speed of 1ms or less. Accordingly, in the 5G communication method, it is possible to support a real-time service that responds before the user recognizes it. For example, the vehicle 100 can receive sensor information from various devices while driving, provide an autonomous driving system through real-time processing, and can provide various remote controls. In addition, the vehicle 100 can process the sensor information with other vehicles 100 existing in the vicinity of the vehicle 100 in real time through the 5G communication method to provide the possibility of occurrence of collision to the user in real time, The traffic information to be generated on the traveling route can be provided in real time.

In addition, through the real-time processing and large-capacity transmission provided by the 5G communication, the vehicle 100 can provide the big data service to the passengers in the vehicle 100. [ For example, the vehicle 100 may analyze various types of web information, SNS information, and the like to provide customized information suitable for the situation of the passengers in the vehicle 100. In one embodiment, the vehicle 100 collects information such as restaurants and sights around the traveling route through the big data mining and provides it in real time so that the passengers can directly check various information existing around the area in which the passengers are traveling I will.

When the communication unit 200 and the base station ST adopt the above-mentioned 5G communication method, the first vehicle 100 can transmit / receive a large amount of information to / from the base station ST at a high speed. In particular, the communication unit 200 of the different first vehicle 100 can receive different traffic information from the base station ST. This will be described later.

The control unit 300 may control the output unit 400 to provide traffic information received from the base station ST to the driver.

The output unit 400 may output information related to the first vehicle 100 so that the occupant including the driver can recognize the visual, audible, or tactile information. In particular, the output unit 400 may output traffic information received from the base station ST in a time, a sound, or a tactile manner under the control of the control unit 300.

To that end, the output unit 400 includes a display 134 for visually outputting information relating to the first vehicle 100; A speaker 160 for audibly outputting information related to the first vehicle 100; A vibration generating unit 410 for tactually outputting information related to the first vehicle 100; . ≪ / RTI >

The display 134 and the speaker 160 are the same as those described with reference to FIG. 2, and a detailed description thereof will be omitted.

The vibration generating unit 410 may output information related to the first vehicle 100 in the form of vibration. For example, the vibration generator 410 may output a vibration corresponding to the traffic information received from the base station ST, which will be described later, and notify the occupant including the driver of the vibration.

For this purpose, the vibration generating unit 410 may be provided at a position where the vibration generating unit 410 can directly contact the occupant. For example, the vibration generating portion 410 is provided on the steering wheel, and can transmit vibration to the driver's hand. Alternatively, the vibration generating unit 410 may be provided on a seat on which a passenger, including a driver, is boarded. However, the position of the vibration generating part 410 is not limited to the above-described embodiment.

The first vehicle 100 according to the above-described embodiment selects one of the plurality of lanes of the road to run. At this time, the driver can select any one of the plurality of lanes in consideration of the traveling route to the destination.

For example, if the destination can be reached by traveling along a road in the left direction at the front intersection, the driver may change the lane in advance to the left-turnable lane at the intersection before reaching the intersection. On the other hand, if the destination can be reached by traveling along the road in the straight ahead direction at the front intersection, the driver can change the lane in advance from the intersection to the straight lane before reaching the intersection.

As such, the lane where the first vehicle 100 is located may include information about a road to which the first vehicle 100 intends to enter at an intersection in the future. Nevertheless, if the same traffic information is provided to the first vehicle 100 located in different lanes, the driver can obtain unnecessary information, and it is troublesome to acquire the acquired traffic information selectively Can occur to the driver.

Therefore, the base station (ST) of the traffic information providing system according to the embodiment acquires traffic information of each of a plurality of sub-roads extending in different directions from the main road, and the transmitting unit (AT) A plurality of traffic information receiving areas capable of receiving respective traffic information on a plurality of sub-roads can be formed in each of a plurality of lanes of the main road. At this time, the main road means the road where the first vehicle 100 is located.

Hereinafter, the operation of the base station base station ST and the transmission unit (AT) will be described in detail with reference to FIG.

5 is a view for explaining a method of providing traffic information by the traffic information providing system according to an embodiment. 5 is a diagram showing a main road M of a reciprocating six-lane line consisting of an upward three-lane line M1 and a downward three-lane line M2, a first sub-road A extending in different directions from the main road, B), and a third sub-road (C).

The base station ST may obtain traffic information of the first sub-road, the second sub-road, and the third sub-road. Here, the traffic information may include an unexpected situation such as traffic flow, accident, congestion, construction, and demonstration.

The base station ST may directly obtain the traffic information of the first sub-road, the second sub-road, and the third sub-road, and may receive the traffic information sensed by the sensing means installed in each sub-road. When the base station ST receives the traffic information sensed by the sensing means installed on each sub-road, the sensing means may include a radar sensor, a lidar sensor, or a vision sensor.

The transmitting unit (AT) can transmit the traffic information to the lane of the main road corresponding to the sub-road at the base station (ST).

5, an ascending lane of the main road M includes a first lane a for turning left at an intersection, a second lane b for straightening at an intersection, and a third lane c for a right turn .

In this case, it can be seen that the first vehicle 100 located on the first lane (a) is going to turn left on the intersection and enter the first road (A). It can also be seen that the first vehicle 100 located in the second lane b is going to go straight on the intersection and enter the second road B. [ In addition, it can be seen that the first vehicle 100 located in the third lane c is going to make a right turn at the intersection and enter the third road C.

Therefore, the transmitting unit AT can transmit the traffic information of the ascending lane A1 of the first sub-road A to the first lane (a). As a result, the first lane (a) may be formed with a first traffic information receiving area capable of receiving traffic information of the ascending lane A1 of the first sub-road (A).

Also, the transmitting unit AT can transmit the traffic information of the up lane B1 of the second sub-road B to the second lane b. As a result, the second lane (b) may be formed with a second traffic information receiving area capable of receiving traffic information of the lane B1 of the second sub-road B.

Similarly, the transmitting unit AT may transmit the traffic information of the ascending lane C1 of the third sub-road C to the third lane c. As a result, a third traffic information receiving area capable of receiving the traffic information of the up lane C1 of the third road C may be formed in the third lane c.

The transmission section AT forms a first traffic information reception area on the first lane a, a second traffic information reception area on the second lane b, and a third traffic information reception area on the third lane c When the first vehicle 100 is located in a specific lane, traffic information may be received according to the traffic information reception area formed in the lane.

For example, when the first vehicle 100 is located in the first lane a, the first vehicle 100 receives the traffic information of the up lane A1 of the first sub-road A from the transmission unit AT . The driver of the first vehicle 100 located in the first lane a does not need the traffic information of the second sub-road B or the third sub-road C, the traffic information of the second sub-road B or the third sub-road C is not transmitted to the vehicle 100 located in the first sub-road a.

When the first vehicle 100 is located in the second lane b, the first vehicle 100 receives the traffic information of the lane B1 of the second sub-road B from the transmission unit AT . In addition, when the first vehicle 100 is located in the third lane c, the first vehicle 100 receives the traffic information of the lane C1 of the third sub-road C from the transmitting unit AT The transmission unit AT transmits only the traffic information necessary for the vehicle 100 located in the different lane so that the driver operating the vehicle 100 can easily recognize the traffic information without discriminating the received traffic information. It can help you to cope flexibly.

In order to transmit different traffic information to the vehicles 100 located in different lanes, the AT may generate the directional beam pattern and transmit the traffic information. To this end, the transmitter (AT) may include a phased array antenna and form a beam pattern in a direction to communicate through the phased array antenna.

Here, the beam pattern may refer to a pattern that appears due to the intensity of a radio signal when the radio signal is concentrated in a specific direction. The phased array antenna is an antenna capable of controlling the beam pattern of the entire array antenna by regularly arranging the unit antenna elements and controlling the phase difference of the radio signal output from each unit antenna element.

At this time, when the main direction of the beam pattern of the radio wave to be output from the array antenna is?, The phase difference ?? of the radio signal output from each unit antenna element can be expressed by Equation (1).

[Equation 1]

(? Is the phase difference, d is the interval between the unit antennas,? Is the wavelength of the carrier wave, and? Is the main direction of the beam pattern).

According to the formula (1), the main direction (?) Of the beam pattern is determined by the phase difference (?) Between the unit antennas and the interval between the unit antennas.

Also, the 3 dB beam width BW of the beam pattern to be output from the array antenna can be expressed by Equation (2).

&Quot; (2) "

(Where BW is the beam width of the beam pattern, d is the spacing between the unit antennas,? Is the wavelength of the carrier wave, and N is the number of array antennas).

According to Equation (2), the beam width of the beam pattern is determined by the interval between unit antennas and the number of unit antennas.

The transmitting unit (AT) can determine the direction of the beam pattern by controlling the phase difference between the phased array antenna and the middle antenna. As a result, the transmitting unit (AT) can form a traffic information receiving area capable of receiving traffic information of different sub roads in different lanes.

Meanwhile, as described above, the AT transmits the traffic information to the first vehicle 100 by forming a directional beam pattern. At this time, the first vehicle 100 located at the boundary of the lane may receive the traffic information on the road other than the planned entry road from the transmission unit (AT).

In order to solve this problem, the transmission unit (AT) can refer to the navigation path of the first vehicle 100. [ That is, the first vehicle 100 can transmit the navigation path to the AT through the communication unit 200, and the AT can transmit it to the base station ST. The base station ST may transmit the traffic information for the planned entry road through the AT by referring to the received navigation route. In this case, the base station ST may adopt either a lane in which the first vehicle 100 is located and a navigation path in order to determine which road traffic information is to be transmitted. Alternatively, the base station ST may digitize the two information, .

Particularly, with respect to the first vehicle 100 traveling along the center line of the road, the base station ST provides the traffic information through the transmission unit AT only to the first vehicle 100 moving in a predetermined direction . Specifically, after determining the moving direction of the first vehicle 100, the base station ST may transmit the traffic information through the transmitting unit (AT) only when the first vehicle 100 faces the road on which the traffic information is obtained have.

6A and 6B are views for explaining a method of determining a moving direction of a vehicle by the traffic information providing system according to an embodiment. 6A and 6B, L is not a line physically present on the baseline.

In order to determine the moving direction of the first vehicle 100, the base station ST may preset the reference position. The base station ST may include the position of the base station ST in one embodiment of the reference position, and the base station ST sets a virtual reference line as a reference position in Figs. 6A and 6B.

First, the base station ST can confirm the distance between the first vehicle 100 and the reference position through the AT. Referring to FIG. 6A, the base station ST can confirm that the distance between the C1 vehicle and the reference line L is d11, and that the distance between the C2 vehicle and the reference line L is d21.

Then, the base station ST can again confirm the distance between the vehicle and the reference position through the transmission unit (AT) after a predetermined time has elapsed. Referring to FIG. 6B, the base station ST can confirm that the distance between the C1 vehicle and the reference line L is d12, and confirm that the distance between the C2 vehicle and the reference line L is d22.

Finally, the base station ST can determine the direction of movement of the vehicle based on the change in distance between the vehicle and the reference position for a predetermined time. According to the example described above, the base station ST can determine that the C1 vehicle is traveling in the direction approaching the reference line L, and can determine that the C2 vehicle travels in the direction away from the reference line L. [

If it is possible to enter the first sub-road in the direction approaching the reference line L, the base station ST can transmit the traffic information of the first sub-road through the transmission unit (AT) only to the C1 vehicle, The traffic information of the first sub-road may not be provided.

Referring again to FIG. 3, the traffic information delivery system according to the embodiment acquires the traffic information on the subway while driving any one of the plurality of subways, and transmits the second vehicle 100a entering the main road from the subway .

The second vehicle 100a may form a traffic information receiving area capable of receiving traffic information on the subway that has traveled in the lane of the main road corresponding to the subway that has traveled. To this end, the second vehicle 100a may transmit a beam pattern including traffic information on the sub-road that has traveled in the lane of the main road corresponding to the sub-road in which the vehicle was traveling. To transmit the beam pattern, the second vehicle 100a may include a phased array antenna.

5, the second vehicle 100a includes a down lane A2 of the first sub-road A, a down lane B2 of the second sub-road B, or a third sub- It is possible to obtain the traffic information of the lane on the sub-lane while driving the lane C2. To this end, the second vehicle 100a may include a vision sensor, and the vision sensor may acquire the traffic information of the up lane on the sub-road so that it can be reproduced in a time lapse manner.

Next, the second vehicle 100a may form a traffic information receiving area capable of receiving traffic information on the sub-road corresponding to the sub-road that has traveled while entering the down lane M2 of the main road M.

For example, when the second vehicle 100a travels the downhill lane A2 of the first sub-road A, the second vehicle 100a is driven by the first lane A2 for entering the first sub- the first traffic information receiving area capable of receiving the traffic information of the ascending lane A1 of the first sub-road A can be formed in (a).

When the second vehicle 100a runs on the downhill lane B2 of the second sub-road B, for example, the second vehicle 100a is moved to the second sub- A second traffic information receiving area capable of receiving traffic information of the lane B1 of the second sub-road B can be formed in the second lane b.

In addition, when the second vehicle 100a travels in the downhill lane C2 of the third sub-road C, the second vehicle 100a enters the third lane C for entering the third sub-road C a third traffic information receiving area capable of receiving traffic information of the ascending lane C1 of the third sub-road C can be formed.

(510) To this end, the transmitting unit (AT) may transmit a beam pattern including traffic information of each sub-road to a lane corresponding to each of a plurality of sub-roads. After the traffic information receiving area is formed, the vehicle located in the traffic information receiving area can receive the traffic information on the subway that can enter through the corresponding lane. (520) Finally, the vehicle can output the traffic information of the received sub-road and provide it to the driver. (520) Since the traffic information thus outputted is the traffic information of the subway that the vehicle 100 is about to enter, the driver can operate the vehicle 100 based on the necessary information without receiving the information irrelevant to the travel route .

8 is a detailed flowchart of a traffic information providing method according to an embodiment.

First, the base station can obtain traffic information of the first sub-road extending in the first direction from the main road. (600-1) In a similar manner, the base station may obtain traffic information of the n-th sub-road extending in the n-th direction from the main road (n is a natural number of 2 or more)

Next, the transmitting unit (AT) may form a first traffic information receiving area capable of receiving traffic information of the first sub-road in the first lane for entering the first road. (610-1) In a similar manner, the transmitting unit (AT) may form an n-th traffic information receiving area capable of receiving traffic information of the n-th subway in the n-th lane for entry into the n-th road. (610-n)

After the traffic information receiving area is formed, the vehicle located in the first lane can receive the traffic information of the first sub-road. (620-1) In a similar manner, the vehicle located in the nth lane can receive the traffic information of the nth sub-road. (620-n)

Finally, the vehicle located in the first lane can output the traffic information of the first road received from the base station. (630-1) In a similar manner, the vehicle located in the nth lane can output traffic information on the nth road received from the base station. (630-n)

Accordingly, the vehicle 100 can receive only traffic information on a sub-road for entering.

9 is a flowchart of a traffic information providing method according to another embodiment.

First, the base station can obtain traffic information of each of a plurality of sub-roads extending in different directions from the main road. (800)

After acquiring traffic information for each of a plurality of sub-roads, the base station can acquire the distance d1 between the reference position and the vehicle located in any one of the main roads through the transmission unit (AT). (810)

After the predetermined time t0 from the time when the distance d1 is obtained, the base station can obtain the distance d2 between the vehicle and the reference position via the transmission unit (AT). (820)

Then, the base station can confirm whether the value obtained by subtracting d2 from d1 is greater than zero. (830) If the value obtained by subtracting d2 from d1 is negative, the base station ST can determine that the vehicle 100 is moving away from the reference position and can terminate.

On the other hand, if the value obtained by subtracting d1 from d2 is greater than 0, the base station determines that the vehicle approaches the reference position, and can transmit the traffic information of the accessible sub-road to the vehicle in the lane where the vehicle is located. (840)

Finally, the vehicle can output the received traffic information. (850)

According to the above-described embodiment, the base station ST determines whether to transmit the traffic information based on the traveling direction of the vehicle 100 acquired through the transmitting unit (AT), thereby transmitting unnecessary information to the vehicle 100 Can be blocked in advance.
