The result of determining whether the event has occurred and the type of the event is transmitted to the SSID modifying unit 123.

2 is a diagram for explaining an example of modification of a service set identifier.

When the initiation determination unit 121 determines that a predefined event has occurred by the designer or the user, the SSID correction unit 123 in response to this automatically corrects the service set identifier 181 as shown in FIG. 2. I can. The service set identifier 181 is used for mutual identification between devices in wireless LAN-based wireless communication, and usually consists of at least one character string (string). Here, the character string may be formed by singly or in combination of letters, numbers, and/or symbols. A wireless communication device (e.g., a smart phone, etc.) using a wireless communication technology such as Wi-Fi is provided with at least one wireless communication service provider (e.g., an access point (AP)) through the service set identifier 181. Point), etc.) are identified, and based on this, a connection request is sent or connected to the desired service provider. In the first vehicle 100, the service set identifier 181 may have been previously defined by a designer or a user so that an external device (for example, the second vehicle 200) can access the first vehicle 100. I can. For example, the service set identifier 181 of the first vehicle 100 may be defined as a character string 182 (hereinafter, an original character string) such as [FIRST_VEHICLE_SSID] as illustrated in FIG. 2. Of course, such a service set identifier 181 may be arbitrarily defined or changed by a designer or a user. The service set identifier 181 may be stored, for example, in the storage unit 180 or the like.

According to an embodiment, when it is determined that a predetermined event has occurred, the SSID modifying unit 123 uses the service set identifier 181 as a character string corresponding to the event generated from the original character string 182 in response to the occurrence of the event. 190, hereinafter, the corresponding string) can be modified. In this case, the SSID modifying unit 123 may modify the service set identifier 181 using different correspondence strings 191 to 199 according to the type of the event that has occurred. More specifically, for example, if an accident occurs in the first vehicle 100, the SSID correction unit 123 converts the existing original string 190 into a response string 191 corresponding to the accident, for example, an image. The service set identifier 181 can be modified by replacing it with a character string corresponding to the request, [Accident Create]). If an event that requires external lighting occurs in the dark or due to the occurrence of an accident in the first vehicle or surroundings, the SSID revision unit 123 responds to the response string (192, for example, [Flash On]) corresponding to the request for lighting the lamp. ]) may be used to modify the service set identifier 181. In addition, the SSID correction unit 123 stores data 281 in the second vehicle 200 according to the occurrence of an accident, for example, the name, phone number, vehicle number, engine speed, mileage, and the like of the owner or driver stored in advance. If data formed including at least one character, such as at least one letter, symbol and/or number, such as battery voltage and/or residual fuel, etc.) are required, respond to a request to send stored data (281, for example, a phone number) The service set identifier 181 may be modified with the corresponding string 193 (for example, [Request Phone]). According to an embodiment, the SSID modifying unit 123 may modify the service set identifier 181 by combining at least two or more of a plurality of previously stored corresponding strings 191 to 193. For example, if an accident occurs and an image captured by the second vehicle 200 and the storage data 281 of the second vehicle 200 (for example, a phone number, etc.) are required, the SSID correction unit 123 Is a service using a string (197, for example, [Accident Create, Request Phone]) that combines a response string (191) corresponding to the occurrence of an accident and a response string (193) corresponding to a request to send the stored data (281). The set identifier 181 may be modified. When modifying the service set identifier 181 to a combination of a plurality of correspondence strings (191 to 193), the combined correspondence strings 197 are a predetermined symbol (e.g., For example, a comma (,), a period (.), or an underbar (_), etc.) may be further included.

In addition, according to an embodiment, the SSID modifying unit 123 may modify the service set identifier 181 even when the event ends or a request corresponding to the event is satisfied. For example, when the end determination unit 125 determines that the event has ended or that the second vehicle 200 or the like has performed a necessary operation in response to the event, the SSID modifying unit 123 may use the original character string 182 ) Or by changing from the previously modified corresponding strings 191 to 197 to a corresponding string 199 corresponding to the end of an event, etc. (for example, [Accident Finish]), the service set identifier 181 may be modified.

In addition, the SSID modifying unit 123 may restore the service set identifier 181 that has been changed to another corresponding string 191 to 199 according to a setting predefined by a designer or user to the original value. . The original value may include the original string (182, for example, [FIRST_VEHICLE_SSID], etc.) before the event occurs. The predefined settings include, for example, the lapse of a predefined time, the end of the event, the satisfaction of a request corresponding to the event (for example, reception of an accident video, etc.), a response string corresponding to the end of the event (199 ) May include modification of the service set identifier 181 and/or the lapse of a predetermined time after the modification of the service set identifier 181, but are not limited thereto. Accordingly, after the request situation ends, the service set identifier 181 can be automatically changed back to the original value.

Each of the above-described event types or each of the at least one character string 191 to 199 corresponding to each type of event is illustrative and is not limited thereto. The type of the event and at least one character string corresponding to the event may be defined in the same manner or differently as described above according to an arbitrary selection of a designer or a user. In addition, these at least one corresponding character string (191 to 193, 199, etc.) may be previously stored in the storage unit 180, and may be provided according to the call of the SSID modifying unit 123.

The termination determination unit 125 may determine whether an event or a requested operation is terminated or completed, and may transmit the determination result to the SSID modifying unit 123. In this case, the end determination unit 125 may determine whether to end the event based on a signal transmitted from the event detection unit 110. Specifically, for example, the termination determination unit 125 may determine whether the parking or stopping of the first vehicle 100 is ended (that is, the departure of the first vehicle 100) or whether the accident situation is ended. . In addition, the termination determination unit 125 requests in response to an event using a signal transmitted from the second vehicle 200, a signal generated by the communication unit 170, or data stored in the storage unit 180. It is also possible to determine whether the performed operation (eg, an operation of capturing and transmitting an image of the second vehicle 200 or an operation of transmitting the stored data 281) is completed. In more detail, when the communication unit 170 finishes receiving the image acquired by the second vehicle 200, the end determination unit 125 may determine that the event is ended. Depending on the embodiment, the end determination unit 125 may determine that the event has ended even according to the lapse of a predefined time or an increase in the amount of ambient light. The determination result of the termination determination unit 125 may be transmitted to the SSID modifying unit 123. As described above, the SSID modifying unit 123 determines the value of the service set identifier 181 according to the determination result of the termination determination unit 125, the corresponding string 199 corresponding to the end of the event, or the original string, which is a string before the event. It can be modified by (182) etc.

In an embodiment, the processor 220 of the second vehicle 200 may include an SSID analysis unit 221, an analysis result processing unit 223, and a communication control unit 227. The SSID analysis unit 221, the analysis result processing unit 223, and/or the communication control unit 227 may also be classified as hardware or software as described above.

The SSID analysis unit 221 analyzes the service set identifier 181 of the first vehicle 100 obtained through the communication unit 270, and the service set identifier 181 of the first vehicle 100 is a corresponding string 190 It may be determined whether or not it includes a character string other than the corresponding character string 190 (for example, the original character string 182, etc.). In this case, the processor 200 calls the comparison string 290 stored in the storage unit 280, and compares the called comparison string 290 with the character string of the service set identifier 181 so that the first vehicle 100 It may be determined whether the service set identifier 181 of is included the corresponding string 190. The comparison string 290 may be the same as or different from the corresponding string 190, and some may be the same and some may be different. The number of comparison strings 290 stored in the storage unit 280 of the second vehicle 200 may be less than the number of corresponding strings 190 stored in the storage unit 180 of the first vehicle 100, Alternatively, there may be more than the number of corresponding strings 190. According to the comparison result of at least one of the correspondence string 190 and the comparison string 290 of the service set identifier 181, if the service set identifier 181 obtained from the first vehicle 100 is at least one correspondence string If it is determined that 190 is not included, the SSID analysis unit 221 may determine that there is no requirement of the first vehicle 100 and may maintain the existing state as it is without performing a separate operation. Conversely, if it is determined that the service set identifier 181 of the first vehicle 100 includes a predetermined corresponding character string 190 (191 to 199), the SSID analysis unit 221 determines that the first vehicle 100 It is determined that an operation corresponding to the corresponding string 190 is requested, and the determination result is transmitted to the analysis result processing unit 223 so that the second vehicle 200 may perform the requested operation. If the service set identifier 181 of the first vehicle 100 is composed of a combined correspondence string 197 consisting of a plurality of correspondence strings (191 to 193, 199, etc.), the SSID analyzer 221 corresponds to each To distinguish the character strings 191 to 193, each corresponding character string (191 to 193, 199) is extracted based on a predetermined symbol, and each of the extracted corresponding character strings (191 to 193, 199) is previously stored. It may be compared with the comparison string 290 to determine whether there is a request from the first vehicle 100.

The analysis result processing unit 223 generates at least one control signal corresponding to the analysis result according to the analysis result of the service set identifier 181 of the first vehicle 100 of the SSID analysis unit 221, and the analysis result At least one control signal may be transmitted to at least one controlled target 210 corresponding to. In other words, the second vehicle 200 may perform a predetermined operation corresponding to the content of the service set identifier 181 of the first vehicle 100.

If, as a result of the analysis by the SSID analysis unit 221, the service set identifier 181 of the first vehicle 100 includes a response string 191 corresponding to the occurrence of an accident, the analysis result processing unit 223 is the camera 211 A control signal for an operation of is generated and transmitted to the camera 211 to cause the camera 211 to start capturing an image. According to an embodiment, the analysis result processing unit 223 may further search and confirm whether or not an image photographed before the acquisition of the service set identifier 181 exists. After that, the analysis result processing unit 223 is configured by the communication unit 270 under the control of the analysis result processing unit 223 to obtain the image captured by the camera 211 and/or the existing image captured prior to the acquisition of the service set identifier 181. The image may be transmitted to the first vehicle 100. In addition, if it is analyzed that the service set identifier 181 of the first vehicle 100 includes a corresponding string 192 related to lighting of the lighting lamp, the analysis result processing unit 223 transmits a control signal to the lighting lamp 213 The lighting lamp 213 may be continuously or for a certain period of time. In addition, the analysis result processing unit 223, if the service set identifier 181 of the first vehicle 100 includes a corresponding string 193 for sending the stored data 281, the communication control unit 227 according to the embodiment. By controlling the communication unit 270 through ), the stored data 281 may be directly transmitted to the first vehicle 100. In this case, the analysis result processing unit 223 modifies the service set identifier (not shown or 282 in FIG. 7) of the second vehicle 200 so that the service set identifier of the second vehicle 200 is changed to the second vehicle 200. After including the stored data 281 for, the communication unit 270 periodically or aperiodically broadcasts a packet including the service set identifier of the second vehicle 200 in which the phone number is recorded. You may. Here, the modified service set identifier of the second vehicle 200 may include only the stored data 281, or, in addition to the stored data 281, to distinguish other character strings and stored data 281 from other character strings. It may further include a predetermined symbol for. Broadcasting may be performed only for a certain period of time, or may be continuously performed. If the service set identifier 181 of the first vehicle 100 includes the character string 199 corresponding to the end of the event, the analysis result processing unit 223 responds to the control target 210 or the communication unit 270, etc. It may be controlled to terminate the operation requested by the first vehicle 100. For example, the analysis result processing unit 223 may transmit a control signal for stopping recording to the camera 211 so that the camera 211 no longer performs recording. In this case, the communication unit 270 may start transmission of the recorded image to the first vehicle 100 from the start of the recording to the stop of the recording under the control of the processor 220 in response to the stop of the recording. In addition, the analysis result processing unit 223 may transmit a control signal to the lighting lamp to flash the lamp. In addition, for another example, the analysis result processing unit 223 re-modifies the service set identifier of the second vehicle 200, which was previously modified to include the stored data 281, etc., to the original character string, Can also be restored. The analysis result processing unit 223 may control one controlled target 210 or the communication unit 270 in response to the analysis result of the SSID analysis unit 221, or a plurality of controlled targets ( 210) or the communication unit 270 may be controlled simultaneously or sequentially.

The communication control unit 227 may control an operation of the communication unit 270 of the second vehicle 200. The communication control unit 227 may cause the communication unit 270 to operate in at least one of the access point mode 271 and the station mode 273, similar to the communication control unit 127 of the first vehicle 100. . For example, the communication control unit 227 may cause the communication unit 270 to operate in the station mode 273 when an accident occurs, and when a phone number is requested, the communication unit 270 may use the access point mode 271 and the station mode. It can be controlled to operate with any one of (273). Depending on the embodiment, the communication control unit 227 may be omitted.

According to an embodiment, the communication unit 270 may operate in the access point mode 271 and/or the station mode 273 according to a preset setting or control of the communication control unit 227. Here, the access point mode 271 and the station mode 273 may be classified by hardware or by software. When the communication unit 270 operates in the station mode 273, the communication unit 270 connects to the communication unit 170 of the first vehicle 100 and transmits predetermined data to the communication unit 170 of the first vehicle 100. (Video, audio and/or text data, etc.) can be transmitted. Depending on the embodiment, transmitted data may or may not be encrypted.

For example, if the service set identifier 181 of the first vehicle 100 includes a character string 191 related to an accident, the communication unit 270 operates in the station mode 273 and the access point mode 171 It is possible to access the communication unit 170 of the first vehicle 100 operating as ). In this case, the communication unit 270 may identify the communication unit 170 to be accessed using the modified service set identifier 181, and access the communication unit 170 of the first vehicle 100 based on this.

If the transmission of the image is terminated, the communication unit 270 may terminate the operation in the station mode 273 and terminate the connection with the communication unit 170 of the first vehicle 100 according to an embodiment. In addition, for another example, if the service set identifier 181 of the first vehicle 100 includes the character string 193 for requesting the storage data 281, the communication unit 270 is in the access point mode ( The service set identifier (which may include at least one stored data 281) of the second vehicle modified by the analysis result processing unit 223 may be broadcast to the outside by operating as 271). Similar to the case of the first vehicle 100, the communication unit 270 of the second vehicle 200 may also transmit a service set identifier to the outside through at least one packet, where the packet may include a beacon packet. Then, the first vehicle 100 uses the processor 120 and the communication unit 170 to check the service set identifier of the second vehicle recorded in the header of the beacon packet, and the desired stored data from the service set identifier of the second vehicle. (281) can be acquired. On the other hand, if the service set identifier 181 of the first vehicle 100 includes the character string 192 for lighting the lamp, only the lamp 212 operates and the communication unit 270 is The connection operation to the communication unit 170 is not performed. In other words, the second vehicle 200 communicates with the first vehicle 100 only when necessary according to the content of the service set identifier 181 of the first vehicle 100, otherwise the communication connection is not possible. I can.

The storage unit 280 may temporarily or non-temporarily store at least one piece of data necessary for the operation of the processor 220 of the second vehicle 200. For example, the storage unit 280 may store the comparison string 290 used by the SSID analysis unit 221 or the storage data 281 to be transmitted or broadcast directly to the first vehicle 100. Here, the storage data 281 includes various information about the second vehicle 200, for example, the name of the owner or driver, phone number, vehicle number, engine speed, mileage, battery voltage, and/or residual fuel. It can also be included. In addition, the storage unit 280 may include, for example, an image captured by the camera 211, a service set identifier of the second vehicle 200, or the second vehicle 200 modified by the analysis result processing unit 223.

As shown in FIG. 3, first, when an accident occurs in the first vehicle 100 and the first vehicle detects the accident, the SSID correction unit 123 of the first vehicle 100 sets the service set identifier 181. The character string 191 corresponding to the accident, for example, can be modified by changing to [Accident Create]. The communication unit 170 of the first vehicle 100 may operate in the access point mode 171 to broadcast the changed and modified service set identifier 181 to the outside in the form of a beacon signal. The second vehicle 200 receives the broadcast beacon signal and analyzes the service set identifier 181 of the received beacon signal through the SSID analyzer 221 to determine what the first vehicle 100 requests. have. Thereafter, the second vehicle 200 performs an operation corresponding to the request of the first vehicle 100. For example, the second vehicle 200 may capture an image by controlling the camera 211. In addition, the communication unit 270 of the second vehicle 200, while the image is being photographed, or after the image capturing is terminated by checking the corresponding string 199 corresponding to the end of the event or by a predefined setting. Sequentially, a captured image or a previously stored image may be transmitted to the communication unit 170 of the first vehicle 100 by accessing the communication unit 170 of the first vehicle 100 operating in the access point mode 171. . In this case, the communication unit 270 of the second vehicle 200 may operate in the station mode 273 to access the communication unit 170 of the first vehicle 100 and transmit data.

A situation in which the second vehicle 200 operates according to the request of the first vehicle 100 (for example, transmits an image to the first vehicle 100, or transmits a phone number, etc. to the service set identifier of the second vehicle 200) In the situation of broadcasting through, etc.), if the first vehicle 100 is required to acquire images or stored data 281 related to an accident from the second vehicle 200 or another vehicle (not shown), or If it is determined that is finished, the SSID correction unit 123 of the first vehicle 100 corrects the service set identifier 181 to a corresponding string (199, for example, [Accident Finish]) corresponding to the end of the event. And, the modified service set identifier 181 may be broadcast in the form of a beacon signal or the like. The second vehicle 200 may receive a beacon signal or the like, and determine that the event has ended by analyzing the service set identifier 181 recorded on the received beacon signal or the like through the SSID analyzer 221. In response to this, the analysis result processing unit 223 controls the controlled target 210 to stop the operation according to the request of the first vehicle 100, or directly or indirectly through the communication control unit 227, the communication unit 270. Can be controlled. Accordingly, the second vehicle 200 stops the operation according to the request of the first vehicle 100. For example, the second vehicle 200 stops capturing an image or transmitting an image to the first vehicle 100.

5 is a view for explaining an example of a headlight lighting request process.

As shown in FIG. 5, when a reason for requiring lighting occurs due to occurrence of a problem such as an accident or theft or the darkness of the surrounding environment, the SSID correction unit 123 of the first vehicle 100 may perform the first vehicle ( By modifying the service set identifier 181 of 100), the previously stored character string (for example, the original character string 182) can be changed to the character string 192 related to lighting lighting. The modified service set identifier 181 is broadcasted to the outside in the form of a beacon signal, etc., and the second vehicle 200 receiving the beacon signal or the like uses the service set identifier 181 included in the header of the received beacon signal By analyzing through the SSID analysis unit 221, it can be confirmed and determined that the first vehicle 100 requests that the lighting lamp be turned on. The analysis result processing unit 223 of the second vehicle 200 turns on the headlight 223a in response thereto. Accordingly, the lighting operation desired by the first vehicle 100 may be performed.

6 is a diagram for explaining an example of a storage data transmission request process.

As shown in FIG. 6, when a reason for requiring other vehicle data (eg, phone number or vehicle number) occurs due to an accident or the like, the SSID correction unit 123 of the first vehicle 100 The service set identifier 181 of the first vehicle 100 is modified to a character string 193 for a phone number request, and the communication unit 170 operates in the access point mode 171 to obtain the modified service set identifier 181. You can broadcast to the outside. As described above, the service set identifier 181 may be recorded in the header of the beacon packet and transmitted to the outside. The second vehicle 200 receives the beacon packet and analyzes the service set identifier 181 recorded in the header of the beacon packet through the SSID analysis unit 221, and identifies or detects the character string 193 for the phone number request. By doing so, it can be determined that the first vehicle 100 is requesting a phone number. In this case, the analysis result processing unit 223 of the second vehicle 200 corrects the contents of the service set identifier of the second vehicle 200 to at least one phone number stored in the second vehicle 200, and the communication unit 270 ) May operate in the access point mode 271 to broadcast the service set identifier of the second vehicle 200 to the outside. In this case, the second vehicle 200 may broadcast the service set identifier of the second vehicle 200 to the outside through a beacon packet. The first vehicle 100 receives the beacon packet broadcast by the second vehicle 200, and the processor of the first vehicle 100 analyzes the beacon packet to quickly obtain the phone number of the second vehicle 200 can do. In the above-described process, the first vehicle 100 and the second vehicle 200 are not connected to each other through a separate network. That is, even without a direct communication connection, the first vehicle 100 can communicate that the phone number is required to the second vehicle 200 and can obtain the requested phone number from the second vehicle 200.

Hereinafter, a communication processing system further including first to third vehicles will be described with reference to FIGS. 7 to 9.

7 is a block diagram of an embodiment of a communication processing system further including a third vehicle, and FIG. 8 is a diagram for explaining another example of modification of a service set identifier.

As described above, the event detection unit 110 detects whether at least one event (eg, occurrence of an accident, occurrence of need for external lighting, operation of other vehicles or users, etc.) occurs, and the detection result May be transferred to the processor 120, the communication unit 170, or the storage unit 180.

The processor 120 determines whether or not at least one specific event occurs according to the detection result of the event detection unit 110, and in response to the occurrence of at least one specific event, the processor 120 ) Can be used to automatically change the service set identifier 181. According to an embodiment, at this time, the processor 120 may also determine whether to transmit the request to the third vehicle 300. If it is determined to forward the request to the third vehicle 300, the processor 120, as shown in FIG. 8, sends a service set identifier 181 including the original string 182 corresponding to the delivery of the request. It can be modified to include the corresponding string 198 (for example, [Extend]). In this case, the processor 120 combines the response string 198 corresponding to the request delivery with the response string 191 for the desired operation (for example, a response string corresponding to an accident) to create a service set identifier 181 You can also modify it. In other words, the service set identifier 181 may include a correspondence string 191 for a desired operation and a correspondence string 198 corresponding to request delivery. In this case, both correspondence strings 191 and 198 may be distinguished through a predetermined symbol (for example, a comma) added to the service set identifier 181. In addition, the processor 120 may control the communication unit 170 according to an event that has occurred so that the communication unit 170 operates in at least one of the access point mode 171 and the station mode 172.

For example, the processor 220, as shown in Figure 8, the service set identifier 181 of the first vehicle 100 is a response corresponding to the transmission of the request to another vehicle, for example, the third vehicle 300 If the character string 198 is included, the service set identifier along with the corresponding character string 198 corresponding to the transfer of the request to another corresponding character string (191, that is, a character string corresponding to the requested operation) A control signal corresponding to the corresponding string included in (181)) is generated and transmitted to the third vehicle 300 through the communication unit 270 or the service set identifier 282 of the third vehicle 300 is modified. Thus, the third vehicle 300 may be able to grasp the request content in the same manner as the second vehicle 200. In the latter case, the processor 220 extracts only the other correspondence string 191 from the service set identifier 181 of the first vehicle 100, and then uses the extracted other correspondence string 191. The service set identifier 282 can be modified. The service set identifier 282 of the second vehicle 200 modified as described above may be broadcast to the outside through the communication unit 270, and the third vehicle 300 receives the broadcasted signal and receives the broadcast signal. By checking the service set identifier 282 of 200), it is possible to determine what the first vehicle 100 requests. In addition, the processor 220 may control the communication unit 270 to operate in one of the access point mode 271 and the station mode 273 or to operate in both modes 271 and 273 at the same time.

14 is a first flowchart for a second embodiment of a communication processing method, and FIG. 15 is a second flowchart for a second embodiment of the communication processing method. 16 is a third flowchart of the second embodiment of the communication processing method.

As shown in FIG. 14, as described above, it is determined whether at least one event defined by a designer or a user occurs in the first vehicle or the like (1010).

If at least one event has occurred (example of 1010), the first vehicle or the like may obtain at least one correspondence string corresponding to each of the at least one event from a storage unit or the like (1012). At least one corresponding string may be predefined by a designer or a user.

The first vehicle or the like may automatically modify the service set identifier of the first vehicle, etc. by using the acquired at least one corresponding string. Accordingly, the service set identifier of the first vehicle or the like may include at least one correspondence string corresponding to each event in response to the occurrence of the event. The at least one response string may include, for example, a response string corresponding to the occurrence of an accident, a response string corresponding to lighting of a light, or a response string corresponding to a request for sending stored data, but is not limited thereto. According to an embodiment, the service set identifier of the first vehicle or the like may include a plurality of correspondence strings. For example, the service set identifier may include at least two of a response string corresponding to the occurrence of an accident, a response string corresponding to lighting of a lighting lamp, a response string corresponding to a request for sending stored data, and a response string corresponding to the request delivery. In this case, each of the two or more corresponding strings may be separated by using a predetermined symbol (for example, a comma (,), a period (.), or an underscore (_)), and may be included by a service set identifier.

The first vehicle or the like may broadcast the modified service set identifier through the communication unit, and a beacon packet or the like may be used for this purpose. A communication unit such as a first vehicle may operate in an access point mode for broadcasting a service set identifier, and the operation according to the access point mode may be performed in response to an event occurrence or modification of a service set identifier.

A packet broadcasted and including a service set identifier is received by a second vehicle or the like, and the second vehicle or the like may analyze and confirm a modified service set identifier of the first vehicle or the like using a processor (1018). In this case, as described above, a comparison string may be used.

The second vehicle or the like may determine whether the service set identifier of the first vehicle or the like includes a corresponding string corresponding to the request transmission (1020 ).

If the service set identifier of the first vehicle, etc. does not contain a corresponding string corresponding to the request delivery (No in 1020), does the second vehicle, etc. contain other corresponding strings as shown in FIGS. 14 and 15? Whether or not it can be determined (1022 to 1034).

Specifically, for example, if the service set identifier of the first vehicle or the like contains a character string for the video request according to the occurrence of an accident (example of 1022), in response to this, the second vehicle or the like is provided in the second vehicle or the like, or A camera device that is electrically connected to a second vehicle or the like may be controlled to start recording an image (1024). When the video recording is started and a certain time elapses, the image is transmitted to the first vehicle, etc., or a character string corresponding to the end of the event is confirmed from the service set identifier obtained from the first vehicle, etc., as described below with reference to FIG. 15 , Can be terminated. If the service set identifier of the first vehicle or the like does not include a character string related to the video request according to the occurrence of an accident (1022), for the second vehicle, for example, the service set identifier is stored data (for example, a phone number). It can be determined whether the corresponding string for the request of is included (1028).

When image data including an accident scene or the like is acquired according to photographing, the second vehicle or the like may access the first vehicle or the like and transmit the acquired image data (1026). In this case, the communication unit such as the second vehicle may operate in the station mode and may connect to the communication unit such as the first vehicle operating in the access point mode and transmit the image data. That is, in the case of transmission of image data, a data network is formed between the first vehicle and the second vehicle.

If the service set identifier of the first vehicle, etc., includes a stored data correspondence string, for example, a correspondence string to a phone number (example of 1028), the second vehicle, etc., in one embodiment, the second vehicle, etc. The service set identifier may be modified (1030). In this case, the second vehicle or the like may modify the service set identifier to include stored data requested by the first vehicle or the like, that is, a phone number. The service set identifier of the modified second vehicle or the like is broadcasted to the outside. In this case, a communication unit such as a second vehicle may broadcast a service set identifier such as a second vehicle using a beacon packet, and may operate in an access point mode for this purpose. Meanwhile, a communication unit such as a first vehicle may operate in a station mode to receive a signal broadcasted by a communication unit such as a second vehicle, and analyze the service set identifier of the second vehicle obtained through this to analyze the second vehicle, etc. You can obtain the stored data of. In this case, a data network is not formed between the first vehicle and the second vehicle. In another embodiment, the second vehicle or the like may directly transmit the phone number to the first vehicle or the like by using a communication unit such as a second vehicle operating in a station mode as in the case of transmitting image data. In this case, a network is formed between the first vehicle and the second vehicle. If the service set identifier of the first vehicle, etc., does not include a corresponding string for the transmission of stored data (No in 1028), the second vehicle, etc., corresponds to lighting of the service set identifier of the first vehicle, for example. Whether or not a character string is included may be determined (1032).

If the service set identifier of the first vehicle, etc., contains a corresponding string for the request to turn on the lighting lamp (example of 1032), the second vehicle, etc., controls lighting such as headlights or turn indicators according to a preset setting, and the lighting lamp is turned on. Or blink (1034).

It may be processed in a different order. For example, determination of the existence of a response string to a request for stored data (1028) or determination of the existence of a response string related to a lighting request (1032) is based on the existence of a response string to a request for an accident-related video. It may be performed prior to the determination 1022 for. In addition, the determination processes 1022, 1028, and 1032 for each of these requests or the operation processes 1024, 1026, 1028, and 1034 corresponding thereto may all be performed simultaneously or may be independently performed as necessary. In addition, these corresponding strings may be analyzed by a second vehicle or the like based on various sequences that can be considered by a designer or the like.

According to an embodiment, the above-described processes 1010 to 1034 may be repeated one or more times according to a predefined setting or a user's operation (example of 1036).

On the other hand, as shown in FIGS. 14 and 16, if the service set identifier of the first vehicle or the like includes a corresponding string corresponding to the request transmission (example of 1020), the communication unit of the second vehicle, etc. It can operate in station mode (1038). Prior to or following the operation 1038 of the communication unit such as the second vehicle, or at the same time as the operation 1038 of the communication unit such as the second vehicle, the second vehicle, etc., the second vehicle, etc., the third vehicle or the third communication process. A character string to be transmitted to the device (hereinafter referred to as a third vehicle, etc.) (that is, a character string corresponding to a request of the first vehicle, etc.) may be generated (1040). In this case, the second vehicle or the like may generate a character string to be transmitted to the third vehicle or the like using the remaining corresponding character strings excluding the corresponding character string portion corresponding to the request transmission among the service set identifiers of the first vehicle and the like.

The generated character string may be transmitted to a third vehicle or the like (1042). According to an embodiment, the second vehicle or the like may modify the service set identifier of the second vehicle, etc. using the generated character string, and broadcast the service set identifier of the second vehicle, etc. to the outside through a beacon packet. I can. Here, the communication unit such as the second vehicle may operate in the access point mode. The third vehicle or the like may receive the broadcasted service set identifier, analyze the service set identifier of the second vehicle, and check the contents of the operation requested by the first vehicle or the like (1044). According to another embodiment, the second vehicle or the like may generate a communication network such as the third vehicle, and then directly transmit the generated character string to the third vehicle or the like through a communication signal. An operation requested by the first vehicle or the like may be confirmed by using a signal received from the third vehicle or the like.

The third vehicle may perform an operation corresponding to the analysis or reception result in response to analysis of the service set identifier of the second vehicle or reception of a signal (1046). Here, the operation of the third vehicle may include photographing and transmitting an image, lighting or flashing a lamp, transmitting a phone number, and/or other preset various operations as described above.

Depending on the embodiment, the above-described processes (1010 to 1018, 1038 to 1046) may be repeatedly performed at least once according to a predefined setting or a user's operation (example of 1048).
