The antenna 152 may be composed of a plurality of types of antennas for a plurality of different types of broadcast / communication signals.

The tuner unit 154 receives the radio wave received by the antenna 152 and converts it into an intermediate frequency signal or the like. In addition, the tuner unit 154 converts the data signal to be transmitted into a form that can be propagated to the air, and sends it to the air through the antenna 152. That is, the tuner unit 154 performs operations such as extracting only a signal of a specific band or combining a data signal with a carrier signal. The tuner unit 154 performs reception of broadcast signals and transmission and reception of communication signals. The broadcast signal may include a radio broadcast signal and a DMB (Digital Multimedia Broadcasting) broadcast signal. The communication signal may include a satellite communication signal with a Global Positioning System satellite (hereinafter, GPS satellite). The communication signal may also include a communication signal for telematics. Which signal is to be received and processed by the tuner unit 154 is determined by a control signal transmitted to the tuner unit 154 in the control unit 112. [ For example, when the control unit 112 generates a control signal to the tuner unit 154 so as to receive a radio broadcast signal of a specific channel, the tuner unit 154 responds to the control signal transmitted from the control unit 112, And receives broadcast signals. If the control unit 112 transmits a control signal and transmission data for transmitting the telematics signal to the tuner unit 154, the tuner unit 154 responds to the control signal transmitted from the control unit 112, And transmits the converted signal through the antenna 152 to the air.

The series of signal processing performed by the broadcast signal processing unit 156 may include analog-to-digital conversion or digital-to-analog conversion, converting the video data into a signal capable of driving the display 114, and the like.

The communication signal processing unit 158 performs processing of a communication signal with the GPS satellite and a telematics communication signal. That is, the communication signal processing unit 158 converts the received communication signal into data to be transmitted to the control unit 112, or transmits the data to be transmitted through the tuner unit 154 and the antenna 152 to the control unit 112, And converts the received signal into a signal of a communicable type.

The navigation database 162 includes data for implementing navigation. The navigation database 162 may be in the form of a memory card or a DVD (Digital Versatile Disc). Navigation data provided from a mobile terminal connected through a wired / wireless link (for example, CarPlay or Android Auto) may be utilized as a navigation database.

The navigation driver 164 forms a navigation screen on the display 114 using data provided from the navigation database 162. To this end, the controller 112 receives navigation setting information such as a destination, a transit route, and a route form set by the driver. In addition, the control unit 112 receives information on the current position of the vehicle secured through communication with the GPS satellite in order to implement navigation.

The audio / video reproducing unit 174 allows the audio / video data input through the audio / video input unit 172 to be outputted to the speaker 116 or the display 114. [ For example, when the audio / video input unit 172 is an optical disc drive, the optical disc drive reads out audio / video data recorded on an optical disc (CD / DVD / BD, etc.) The audio / video reproducing unit 174 converts the audio / video data fetched by the audio / video input unit 172 into a signal capable of driving the speaker 116 or the display 114 to output the audio / To the display 114 so that the audio / video can be reproduced. In the case of audio / video data provided from a medium other than the optical disc, the audio / video data may be converted into a signal capable of driving the speaker 116 or the display 114 while passing through the audio / video reproducing unit 174.

The BLE module (Bluetooth Low Energy Module) 194 is for communicating information with other vehicles via beacon communication. Beacon communication refers to a next-generation local area communication technology through low-power Bluetooth (BLE), which means a local communication technology capable of searching for another BLE module 194 within a radius of 50 m to 70 m and transmitting / receiving data to / from each other. In addition, since beacon communication is low in power consumption and consumes less battery power and the received signal strength indicator (RSSI) varies relatively uniformly according to the distance from the transmitter, The location can be grasped at a very sophisticated level.

The controller 112 is involved in the overall operation of the AVN and performs necessary control. For example, in response to the operation of the voice recognition button 104, an application related to the voice recognition function of the memory 110 is driven to display an initial entry screen and output an associated voice guidance message. In addition, the control unit 112 receives the voice command information provided from the voice recognition processing unit 108, generates a control command corresponding to the voice command information, and performs control corresponding to the voice command information. In addition, the control unit 112 may process the broadcast / communication signal. Video data to be transmitted to the speaker 116 or the display 114 when the audio / video data generated after the processing of the broadcast / communication signal is to be output to the speaker 116 or the display 114 So that output of audio / video data can be performed. When the driver selects the navigation function, the controller 112 controls the navigation database 162, the navigation driver 164, the display 114, and the speaker 116 so that navigation can be implemented. The control unit 112 controls the audio / video data input through the audio / video input unit 172 to be reproduced by the audio / video reproducing unit 174 and transmitted to the speaker 116 or the display 114, / Video data can be output. Further, the control unit 112 receives the detection result of the vehicle state detection unit 192 and monitors whether an abnormality has occurred in a specific part of the vehicle.

4 is a diagram illustrating a configuration for detecting a state of a vehicle according to an embodiment of the present invention. The electronic control device 60 can detect whether or not a warning situation of the vehicle occurs. Here, the electronic control device 60 is a control device capable of sensing the state of the vehicle including the tire air pressure alarm device, the engine control device, the automatic transmission control device, the lane departure warning device, the rectangular area monitoring device, . ≪ / RTI >

For this purpose, the electronic control device 60 may be composed of a plurality of electronic control devices.

The AVN 100 generates alert data including the anomaly information of the vehicle when receiving the alert situation detection information from the electronic control unit 60 or detecting an abnormality of the AVL 100. The AVN 100 transmits the alert data to the BLE module 194, Of beacon communication to other vehicles in the vicinity.

5 is a diagram showing a first embodiment of inter-vehicle communication according to the present invention. The situation shown in FIG. 5 is a situation in which when an abnormal symptom is found in the running vehicle A, the driver informs another vehicle C in the vicinity of the driver of the abnormality of the own vehicle A to ask for help or to call attention. Here, the subject vehicle A means a vehicle that is the subject of communication.

As shown in FIG. 5, when an abnormality is detected in the vehicle A, the alarm data including information on the abnormality of the own vehicle A is generated to request assistance or to call attention, and the BLE module 194 to the vicinity of the own vehicle A. That is, alarm data is transmitted to an unspecified number of vehicles not to transmit alarm data to only a specific vehicle.

FIG. 6 is a diagram illustrating the configuration of alarm data transmitted / received in the vehicle-to-vehicle communication method according to the first embodiment shown in FIG. As shown in FIG. 6, the alarm data according to the first embodiment of the present invention includes GPS, lane information, car number, and error code.

The GPS is a GPS coordinate for indicating the positional information of the subject vehicle A that generates alarm data. 16 bytes are allocated to the GPS. The lane information is a value indicating how many lanes the vehicle A is driving. For example, it indicates whether the subject vehicle A is currently traveling in the first lane or in the second lane. One byte is allocated to the lane information. The vehicle number indicates the number of the number plate of the own vehicle (A). In order for the own vehicle A to inform the other vehicle C of its own abnormality, the other vehicle C must be able to know which vehicle the own vehicle A is, do. 10 bytes are assigned to the car number. The error code indicates what kind of abnormality is found in the own vehicle (A). This may include, for example, an anomalous indication of a hardware device of the vehicle, such as a tire, a braking device, a steering device, as well as a medical anomaly of the occupant (driver and / or passenger). The error code is allocated 4 bytes. The allocation size of each item of alert data shown in Fig. 6 is not limited to one value but may be increased to a larger value or decreased to a smaller value.

The other vehicle C having the BLE module compatible with the BLE module 194 of the own vehicle A receives the alarm data transmitted from the own vehicle A and displays the contents of the alarm data through the speaker or the display . At this time, the content of the received alarm data is displayed in the form of a complete sentence in accordance with a predetermined format in order to make it easier for the occupant of the other vehicle C to understand. For example, a guidance such as " Please note that a problem has occurred in the engine of the rear left OO HI OOOO vehicle "is output to the other vehicle C in the form of a voice signal through the speaker of the other vehicle C, And can be expressed in a character form on the screen. In the contents of the above guiding text, 'rear left' can be known from GPS coordinates and lane information, 'OO HOO OOO' is license plate number, and 'engine trouble' can be known through error code.

7 is a diagram illustrating a method of acquiring lane information using the BLE module. 7, if the BLE module 704 is installed at an appropriate interval on any one of the roads, for example, on the center line 702, the BLE module 194 of the vehicles (A) and (D) Can receive signals sent from the BLE module 704. At this time, by using the difference in the reception intensity of the signal, it is possible to know which lane each of the vehicles (A) and (D) is running on.

3, in the beacon communication of the BLE module, the received signal strength indicator (RSSI) changes relatively uniformly according to the distance from the BLE module, I explained that the position can be grasped at a very sophisticated level.

More specifically, as shown in FIG. 7, the reception intensity of a signal transmitted from the BLE module 704 varies depending on the lane. For example, since the first line is near the center line 702 where the BLE module 704 is installed, the reception strength is about 50 to 70 db. On the other hand, in the case of the second lane, since the distance from the location where the BLE module 704 is installed is decreased, the reception strength is reduced to about 10 to 30 db. If there are three lanes, the reception strength in the third lane will be further reduced. Thus, it is possible to identify to which lane the vehicle A or D that is receiving this signal is traveling, through the reception strength of the signal transmitted from the BLE module 704 installed on the center line 702. [

When the GPS information is not known, the driving lane of the vehicle can be identified through the reception intensity of the signal transmitted from the BLE module 704 as well as the BLE module 704 By operating the reception strength of the signal and the GPS information together, it is possible to more accurately identify the driving lane of the vehicle.

FIG. 8 is a diagram illustrating a method for controlling inter-vehicle communication according to the first embodiment of the present invention based on the situation of FIG. That is, the inter-vehicle communication control method of FIG. 8 is a method of notifying an abnormality of the own vehicle A to another vehicle C in the vicinity when an abnormality is detected in the traveling vehicle A, It is for ventilation.

First, in the vehicle A, the control unit 112 of the AVN 100 receives the vehicle status information of each part from the vehicle status detection unit 192 (802). That is, in the AVN 100, the vehicle state detection unit 192 receives status information of each part of the vehicle from the electronic control unit (see 60 in FIG. 4), detects whether the corresponding part is normal or abnormal, 100 to the control unit 112 of the mobile communication terminal. The control unit 112 of the AVN 100 determines an abnormal symptom of each part based on the analysis of the vehicle state information of each part received from the vehicle state detecting unit 192. [

If no abnormality of the vehicle is found (No in 804), the vehicle condition monitoring unit 192 continues monitoring the vehicle condition.

If an abnormality of the vehicle is found (Yes in 804), the controller 112 of the AVN 100 generates alarm data including the abnormality symptom information of the vehicle (806). The alert data generated at this time includes GPS, lane information, car number, and error code as shown in Fig.

The control unit 112 of the AVN 100 that generated the alarm data transmits the generated warning data through the BLE module 194 (808). At this time, the transmission of the alarm data is performed in the form of broadcasting, so that the alarm data is transmitted to an unspecified number of vehicles not to be transmitted only to a specific vehicle.

Alert data sent out in the form of broadcasting in the own vehicle A may be received (810) by another vehicle C running around the periphery of the own vehicle A. [ The other vehicle C that receives the alarm data needs to have a BLE module of the same or compatible standard as the BLE module 194 of the own vehicle A in order to receive the alarm data transmitted from the own vehicle A .

The other vehicle (C) receiving the alarm data transmitted from the own vehicle (A) displays the contents of the alarm data through the speaker or the display on the received alarm data.
