Description

  The present invention relates to an information communication system, an information communication apparatus, an information communication method, and a program.

  In recent years, the spread of ETC (automatic toll collection system) has been remarkable. In ETC, roadside radio equipment and roadside antennas are installed as fixed stations at tollgates and interchanges on toll roads such as expressways, and between onboard equipment and roadside radio equipment as mobile stations installed in vehicles. Road-to-vehicle communication by narrow-area communication is performed, and tolls are charged based on information such as the time and location of vehicles entering the road.

(For example, refer to Patent Document 1).
JP 2006-318170 A

  In addition to the above-described conventional technology, the following can also be considered. For example, it is conceivable that the communication band for road-to-vehicle communication is expanded by the revision of the communication standard, and it becomes possible to provide detailed information to a traveling vehicle.

  In the future, this high-capacity communication will be used to install roadside radio equipment and roadside antennas as fixed stations not only on expressways but also on general roads and in various places such as private facilities, and use road-to-vehicle communications. Thus, for example, it is considered that various services such as a fee collection service at a parking lot or a gas station, an advertisement service, and a traffic information providing service are provided.

  As one form of such a road-to-vehicle communication service, there is a high possibility that a service for selecting and providing appropriate information on the road according to the movement of the vehicle will be provided to the traveling vehicle.

  For example, the roadside apparatus transmits its own apparatus beacon number that identifies the apparatus by broadcast communication, and the vehicle-mounted device stores the beacon number received during communication with the roadside apparatus. In addition, the roadside wireless device provides road traffic information by broadcast communication, and for each information provided, the beacon number of the roadside device with which the vehicle-mounted device suitable for receiving the information communicates immediately before Is added.

  The in-vehicle device compares the beacon number added to each information with the beacon number of the roadside wireless device received by the vehicle while traveling, and selects only the information that matches the related beacon number. Output.

  However, if these road-to-vehicle communication services focus on the provision of road traffic information, only the provision of information based on the road network is possible, and only simple information provision is possible.

  In other words, sufficient information can be provided if the road network is limited to relatively simple roads such as expressways, but the road network may be very complex when considering general roads. Information may not be provided.

  In particular, assuming a vehicle traveling on a general road, the information required by the driver is not limited to road traffic information, but includes a variety of restaurants, shops, tourist facilities, and the like. For this reason, such an information cannot be provided in one form of the road-to-vehicle communication service described above.

  As shown in FIG. 4, the output data supply signal output device 200B includes a control unit 225, a home periphery detection unit 226, a keyword information storage detection unit 227, an information content / type detection unit 228, and output data that outputs an output data supply signal. It comprises a supply signal output unit 229 and ROM and RAM (not shown). The home periphery detection unit 226, the keyword information storage detection unit 227, and the information content / type detection unit 228 detect whether or not the content data is information desired by the user. These home periphery detection unit 226, keyword information storage detection unit 227, and information content / type detection unit 228 are also referred to as information detection means.

  The control unit 225 controls the entire output data supply signal output device 200B.

  For example, the control unit 225 determines whether or not to output (notify) the content data downlinked from the roadside apparatus 100 to the user, whether the home periphery detection unit 226, the keyword information storage detection unit 227, or the information content / type A determination is made based on the detection results from each of the detection units 228. Specifically, when the roadside apparatus wireless communication unit 211 receives the latest content data downlinked from the roadside apparatus 100, the control unit 207 stores the latest content data in the output data storage unit 212. At the same time, the information is output to the home surroundings detection unit 226, the keyword information storage detection unit 227, or the information content / type detection unit 228 via the I / O device 205 and the control unit 225. Thereafter, the control unit 225 confirms whether the content data downlinked from the roadside apparatus 100 is data that must be reproduced, and outputs (notifies) to the user when the data is not necessarily data to be reproduced. ) Based on the detection results from the home surroundings detection unit 226, the keyword information storage detection unit 227, or the information content / type detection unit 228.

  If the control unit 225 determines that the content data is to be notified to the user, the control unit 225 controls the output data supply signal output unit 229 to output “1” as an output data supply signal, for example. The output data supply signal “1” is output to the control unit 207 of the ITS in-vehicle device 200A via the I / O device 205. Thus, the control unit 207 notifies the user of the content data by outputting the latest content data stored in the output data storage unit 212 to the information output unit (such as the monitor device of the speaker 222 and the output unit 203). To do.

  On the other hand, when the control unit 225 determines not to notify, the output data supply signal output unit 229 is controlled to output, for example, “0” as the output data supply signal, and the output data supply signal “0”. Is output to the control unit 207 of the ITS in-vehicle device 200A via the I / O device 205. Thereby, the control unit 207 does not output the latest content data stored in the output data storage unit 212 to the information output unit (such as the monitor device of the speaker 222 and the output unit 203). That is, the content data is not notified to the user.

  Hereinafter, the control operation of the control unit 225 (control when not informing content data) based on the detection results of the home periphery detection unit 226, the keyword information storage detection unit 227, or the information content / type detection unit 228 will be described in detail. explain.

  The home periphery detection unit 226 operates according to user settings, and in the case of content data received on a route around the home (within a predetermined distance from the home), it is assumed that the information is not information desired by the user and is output as data The detection result is notified to the control unit 225 so that (user notification) is not performed. Specifically, the home periphery detection unit 226 stores, for example, the route or latitude / longitude of the periphery of the home (within a predetermined distance from the home) in an internal storage unit (not shown). The route or latitude / longitude is input in advance by the user by a predetermined method. Then, when the roadside apparatus 211 receives the latest content data from the roadside apparatus 100, the control unit 207 stores the latest content data in the output data storage unit 212 and the I / O device 205 and the control. It is supplied to the home surroundings detection unit 226 via the unit 225. The home periphery detection unit 226 outputs a predetermined notification signal to the control unit 225 when detecting that the latest content data supplied has been generated (received) around the home. In accordance with this notification, the control unit 225 controls the output data supply signal output unit 229 to send an output data supply signal “0” (an output data supply signal that does not supply content data) via the I / O device 205. It outputs to the control part 207 of ITS onboard equipment 200A. As a result, the control unit 207 does not output the latest content data stored in the output data storage unit 212 to the information output unit. That is, the content data is not notified to the user. Instead of displaying all the information generated in the vicinity of the home, the information may be ranked, and information with higher urgency or higher rank may be output and displayed.

  The keyword information storage detection unit 227 operates according to user settings, and prevents content data not desired by the user from being output from the content data acquired through the downlink. Therefore, a plurality of pieces of keyword information of data that are not desired to be output are stored in a storage unit (also referred to as a keyword information storage unit) inside the keyword information storage detection unit 227. Then, when the content data corresponding to the keyword is received, the keyword information storage detection unit 227 outputs a predetermined notification signal (detection result notification) to the control unit 225 so as not to notify the user. For example, when the content data to be output is a slip caution or a heavy snow caution, and the user lives in an area where there is a lot of snow, such content information is always output. Therefore, if a user who wants to avoid repeated output of such information registers information such as “snow” or “slip” as a keyword, the received content data is “snow” or “slip”. If a word is included, output is not performed. Specifically, when the roadside apparatus wireless communication unit 211 receives the latest content data from the roadside apparatus 100, the control unit 207 of the ITS on-vehicle device 200A stores the latest content data in the output data storage unit 212. At the same time, it is supplied to the keyword information storage detection unit 227 via the I / O device 205 and the control unit 225. The keyword information storage detection unit 227 determines whether the latest content data supplied matches the keyword information stored in the keyword information storage unit or a predetermined ratio or more (for example, what number of characters in the case of character data) If they match, the predetermined notification signal is output to the control unit 225. In accordance with this output, the control unit 225 controls the output data supply signal output unit 229 to send an output data supply signal “0” (an output data supply signal that does not supply content data) via the I / O device 205. Output to the control unit 207. As a result, the control unit 207 does not output the latest content data stored in the output data storage unit 212 to the information output unit. That is, the content data is not notified to the user. The keyword is stored by the user, but may be automatically generated by the apparatus.

  The information content / type detection unit 228 operates according to user settings, outputs a heading obtained from the content / type of content data to the information output means, and outputs an instruction (signal) for all information from the user (operation unit 204). ), The detection result is notified to the control unit 225 so as not to output the content data (notify the user). Specifically, when the roadside apparatus wireless communication unit 211 receives the latest content data from the roadside apparatus 100, the control unit 207 stores the latest content data in the output data storage unit 212 and the I / The information is supplied to the information content / type detection unit 228 via the O device 205 and the control unit 225. The information content / type detection unit 228 refers to a predetermined area (area in which the content / type of content data is recorded) of the packet data (not shown) of the latest content data supplied. Then, information output means (the monitoring device of the speaker 222 or the output unit 203) is provided with a headline (a short concise expression of the content of the content data, which may be newly generated) obtained from the content / type of the content data. Etc.) and supplied from the operation unit 204 (user) via the predetermined signal (the operation unit 204, the control unit 207, the I / O device 205, and the control unit 225) to the information content / type detection unit 228. Wait for signal input. When there is no input of a predetermined (specific) signal, or when there is no input of the signal itself (timeout) even after a predetermined time elapses after the heading is output to the user, content data is output (to the user) The detection result is notified to the control unit 225 so that the notification is not performed. In accordance with this notification, the control unit 225 controls the output data supply signal output unit 229 to send an output data supply signal “0” (an output data supply signal that does not supply content data) via the I / O device 205. It outputs to the control part 207 of ITS onboard equipment 200A. As a result, the control unit 207 does not output the latest content data stored in the output data storage unit 212 to the information output unit. That is, the content data is not notified to the user. The operation unit 204 may be provided in the output data supply signal output device 200B.
