Further, the communication processing unit 24 of the main body device of the roadside apparatus 20 shown in FIG. 3 performs communication control with the vehicle-mounted device 10 using the Internet protocol.

  FIG. 4 is a diagram illustrating a configuration example of the downlink information in the present embodiment. Downlink information is information distributed from the roadside apparatus 20, and includes, for example, audio information, video information, and character information. For example, sound or the like may be modulated and superimposed on a radio wave, or may be transmitted as encoded digital data superimposed on a carrier wave. In the present embodiment, the downlink information constitutes a composite format (multi-content format) configured by ID so as to be compatible with various DSRC application services in one data format. Moreover, it is also a data format in which delivery content can be configured with only necessary items (ID) according to the purpose. Therefore, the multi-content format can reduce network traffic while suppressing the amount of distribution data.

  As shown in FIG. 4, a data group (hereinafter, this data group is referred to as an “information group”) is organized in a multi-content format. Received data including a plurality of information groups from information group 1 to information group n is transmitted from the roadside apparatus 20 to the vehicle-mounted device 10. Each of the plurality of information groups includes basic information such as ID00 and ID01 that includes basic information and information such as ID that is another classification item. These information groups do not necessarily include information of all the division IDs, but are transmitted including only necessary information.

  This multi-content format allows data to be played back at a specific location in conjunction with the car navigation function and guided to a specific location in addition to playing back data in the order in which it was distributed after reception. ing. Further, in this multi-content format, the information content that can be stored in the vehicle-mounted device 10 that has received the distribution can use the distribution data even outside the communication area of the roadside apparatus 20. Yes.

Moreover, since the vehicle-mounted device 10 can operate in consideration of the data distribution source, it is useful for preventing spam. The multi-content format also enables an uplink function from the vehicle-mounted device 10 to the server device 30. In addition, the multi-content format can acquire the action history and the viewing history of the distributed content, including the destination information set in the vehicle-mounted device 10 and the information on the stop-off location.

  FIG. 5 shows an example of a data format of information (content) transmitted from the roadside apparatus 20. As shown in FIG. 5, one content is configured by a file that can store information classified into ID00 to ID80, and stores necessary information according to the content to be provided. Below, the information required for this Embodiment among the information classified into ID00-ID80 is demonstrated.

  The “ID configuration information” classified as ID00 is an area in which ID information included in the content to be distributed is described, as shown in FIG. The data format of ID = 00 has “information byte count” and “item presence / absence information”. “Number of information bytes” is an area indicating the entire data amount of ID = 00. Thereby, it can also be determined whether it is the data which can be received by the onboard equipment 10 side. “Item presence / absence information” is an area in which IDs constituting information can be described in units of 2 bytes in ascending order. Here, all IDs included in the distribution content are described.

  The “enterprise information” classified as ID01 is information relating to a service provider that distributes the content. For example, “enterprise code”, “enterprise name display text” of the service provider that provides the content, and the like. Is included.

  The “content attribute information” classified as ID02 is information indicating the attribute of the content. For example, “information provider company code”, “information provider company name display text” of the information provider that provides the content, content “Information code” for specifying the content, “Information title display text” indicating the content, “Preference data category information” indicating the content category, and the like. Note that the content information has a hierarchical structure, and in the present embodiment, the hierarchy of each content information can be identified by the information code.

  The “target point information” classified as ID10 includes information on a point where the service guided by the content is provided (referred to as a target point) and actual data of the content. “Target point information” is “target point coordinate information” indicating the latitude and longitude of the target point, “service name display text” indicating the name of the service or store provided at the target point, and service description text information. "Display character data", "Display image data" for displaying service guidance, "Phonetic character string data" and "compressed speech data" for service voice guidance, and the target point are displayed on the map screen “Icon image information” and the like are included.

  ID = 80 is an area in which preference data can be written. “Preference data” refers to data in which classification or the like of content selected based on hobbies and preferences of the user who uses the vehicle-mounted device 10 is accumulated or stored. With the preference data, it is possible to provide the user with only information (content) desired by the user from among many advertisements and information possessed by the service provider. Therefore, the user does not have to receive unnecessary information (content). Note that the preference data area is an area in which the configuration can be freely changed for each service provider. The user can select a desired content classification based on the preference table of the service provider.

  FIG. 6 shows an example of a preference table of ID80. The preference table is classified into each genre, and the content of the classification desired by the user can be selected from the preference table. For example, in the genre of “car” in the uppermost hierarchy in FIG. 6, there are genres of “replacement parts” and “road service”. Further, in the hierarchy below the “replacement parts” genre, there are “tire”, “lamp” and “oil”, and in the hierarchy below the “road service” genre, information on “retail store A” and There is information on “Gas station C”. Some items may be substituted for or added to these items.

  In the present embodiment, if “0” is associated with each content, it means that the user does not want the content. On the other hand, when “1” is associated with each content, the user desires that content.

  The user can select a content category desired to be distributed among the content categories described in the preference table. For example, since “1” is associated with “car” as a flag, information about the car is desired. In addition, since “1” is associated with “tire” and “oil” in “replacement parts”, “1” is associated with “tire” and “oil”. Then, the user desires information on “tire” and “oil”. On the other hand, among the “replacement parts”, “lamp” is associated with “0”, and therefore information regarding the lamp is not desired. When the user selects or cancels each content, “1” or “0” associated with the content is changed according to the selection or cancellation.

  FIG. 7 is a diagram illustrating a configuration example of uplink information in the present embodiment. As described above, there are various types of uplink information. In the following, uplink information that is particularly related to the present embodiment will be described. The uplink information includes a preference table version for creating preference data, preference data, member information, and the like in addition to information such as a service provider code, a destination, a stop-in place, and a cumulative travel distance. The uplink information may include any one or more of the above information. The service provider code is a code assigned to each service provider. The cumulative travel distance information is information indicating the cumulative travel distance of the vehicle.

  The destination data indicates the latitude and longitude of the destination set by the user. For example, when the user sets a destination for using the navigation function of the vehicle-mounted device 10, the latitude and longitude of the destination are described in the destination data column of the uplink information. In addition to this, it is also possible to include in the uplink information a waypoint that is scheduled to stop along the way to the destination.

  The stop location data indicates the latitude and longitude of the place where the vehicle 200 on which the vehicle-mounted device 10 is mounted stopped in the past. When the vehicle 200 stops at a certain place, that is, when the vehicle stops, the control unit 6 stores the latitude and longitude of the place where the vehicle has visited together with the date and time of the stop in the storage unit 7. Therefore, the past stop-in place data is data indicating information on what place and how often the user of the vehicle-mounted device 200 stops. In the present embodiment, in order to collect such stopover data, the vehicle 200 equipped with the vehicle-mounted device 10 is a point where the engine is turned off for a certain period of time and the point is not on the road. The control unit 6 records the current value acquired by the GPS receiver or the like as past stopover data. By recording a point corresponding to such a condition as past stopover data, it is possible to prevent the point where the user has performed a so-called idling stop from being recorded as a stopover. Control is performed when only one of the condition that the vehicle 200 equipped with the vehicle-mounted device 10 has the engine turned off for a certain period of time and the condition that the point where the engine is turned off is not on the road is satisfied. The unit 6 may record the point as past stopover data. However, when both conditions are satisfied, it is possible to effectively prevent the point where the idling stop has been performed from being recorded as a stop-by place by recording as the stop-by place data in the past.

  In the present embodiment, past stopover data is stored in the storage unit 7 as follows. First, when the engine of the vehicle 200 is stopped for a predetermined time or longer, the control unit 6 acquires the latitude and longitude of the position where the engine is stopped by a GPS receiver, and compares the acquired latitude and longitude with road data. When the control unit 6 determines that the latitude / longitude is on a road and the engine is restarted within a predetermined time, the latitude / longitude and the time when the engine is restarted are not stored. On the other hand, when it is determined that the latitude / longitude is not on the road, the control unit 6 stores the latitude / longitude and the time when the engine is restarted in the storage unit 7 as stop-by data. Therefore, it is preferable that the storage unit 7 can have a plurality of stopover data.

  The member information shown in FIG. 7 is exchange information that can be freely set for each service provider, and can be used, for example, to save a privilege or the like at the next visit.

  Further, as the downlink information related to the accumulated mileage information included in the uplink information, advertisement contents related to the business or product of the service provider are associated. For example, when the service provider is an automobile parts sales company, advertisement contents of automobile parts handled by the company are associated, and when the service company is an automobile repair company, advertisement contents related to the repair service handled by the company are associated.

  Next, operations of the vehicle-mounted device 10 and the server 30 in the information providing system 1 will be described.

  FIG. 8 is a flowchart showing a processing operation when the information providing system 1 according to the embodiment receives a radio wave from the roadside apparatus 20 operated by a certain service provider.

  The vehicle 200 on which the vehicle-mounted device 10 is mounted enters the communication area of the roadside apparatus 20. Then, PUSH communication is established between the vehicle-mounted device 10 and the roadside apparatus 20, and the server device 30 receives the ASL-ID and the like transmitted from the vehicle-mounted device 10 at that time (step S101: client information). Acquisition step). The control unit 36 of the server device 30 determines whether or not the user is a member based on the ASL-ID or the like (step S102: member determination step).

  When a service provider that transmits information via the roadside apparatus 20 and a user of the vehicle-mounted device 10 have signed a service reception contract, and the control unit 36 determines that the user is a member ( In step S102, YES), control unit 36 transmits a service provider code. The control unit 6 of the vehicle-mounted device 10 that has received the service provider code transmits uplink information including destination data and drop-in value information stored in the storage unit 7 via the roadside apparatus 20. The server 30 receives the uplink information (step S103: uplink information reception step).

  When it is determined that the control unit 6 does not have a reception contract with the service provider, the control unit 6 makes a negative (NO) determination in step S101. The vehicle-mounted device 10 receives public information and solicitation information from the service provider's roadside wireless device 20 by regular polling.

  The server device 30 receives the uplink information transmitted by the vehicle-mounted device 10. Then, the control unit 36 determines whether or not the destination data is included in the received uplink information (step S104: destination data search step).

  When the destination data is included in the uplink information (YES in step S104), the control unit 36 searches the route from the current location to the destination, and follows the route searched via the network 40. Acquire information content and send it as downlink information. For example, the information of the restaurant at the relay point to the destination is acquired and transmitted (step S105: remote location information providing step).

  When a negative determination is made in step S104, and after the process of step S105, the control unit 36 transmits information content provided at the point where the roadside apparatus 20 is installed as downlink information. (Step S106: normal information providing step).

  Downlink information received by the communication unit 3 of the vehicle-mounted device 10 is stored in the storage unit 7 by the control unit 6. Advertisements such as audio, still images, and moving images included in the downlink information stored in the storage unit 7 are appropriately output from the output unit 9.

  As described above, information providing system 1 according to the present embodiment transmits uplink information including destination data. Therefore, the user can acquire the information content regarding the relay point to the destination by the vehicle-mounted device 10. The information providing system 1 can provide useful information to the user.

  Next, an information system 1A according to the second embodiment will be described. FIG. 9 is a flowchart for explaining the operation of each device of the information system 1A according to the second embodiment. Steps S201 to S205 in this flowchart are the same as steps S101 to S105 in the first embodiment, and thus description thereof is omitted.

  When a negative determination is made in step S204 and after the process of step S205, the control unit 36 causes the data storage unit 33 to store past stopover data included in the uplink information. And the control part 36 acquires the information content around the past stop point, and transmits as downlink information (step S206: living area information provision step). Examples of downlink information include restaurant information at past stops and parking lot information.

  Downlink information received by the communication unit 3 of the vehicle-mounted device 10 is stored in the storage unit 7 by the control unit 6. An advertisement such as a voice, a still image, or a moving image included in the downlink information stored in the storage unit 7 is appropriately output from the output unit 9 (step S207: output step).

  As described above, the information providing system 1 according to the present embodiment transmits uplink information including at least one of destination data and stopover data. Therefore, the user can acquire information content regarding the relay point to the destination. In addition, when the destination is not set, only the information within the user's action range, such as a frequently visited place or a way to the frequently visited place, is provided. The information providing system 1 can be provided.

  In addition, since the service provider can obtain information such as the stop-by location of the user without imposing a burden on the user, the information can be utilized in the business strategy of the service business.

  As mentioned above, although embodiment of each invention was described, this invention is not limited to these each embodiment, A various deformation | transformation and combination are possible. For example, in step S104, it may be determined whether or not the data of the planned stopover is received instead of the destination data or in addition to the destination data.

  In each embodiment, regardless of whether the control unit 36 of the server device 30 has obtained the destination data included in the uplink information transmitted from the vehicle-mounted device 10 in step S203, the control unit 36 Information content related to past stopover data is transmitted, but the present invention is not limited to such a form. In general, since the user inputs a destination when going to an unfamiliar place, when the destination data is included in the uplink information, the information content around the past stop-off location may not be transmitted.

  Further, in each embodiment, in step S104, the control unit 36 performs control to transmit information content of an area where a past stopover exists, but the present invention is not limited to such a form. For example, by mapping the stop points to a map based on the latitude and longitude information of past stopovers, the gathered part of the stopovers is regarded as the living area, and the information content provided in the area of the living area is downloaded. It is good also as a form output as ID10 of link information. Alternatively, based on the time information included in the stop location information, the set portion of past stop points corresponding to a predetermined day of the week or time zone is regarded as the action range of the time or day of the week and provided within the range of action. It is good also as a form which provides the information which exists. Alternatively, the control unit 36 may calculate the frequency and period of the stop-by at the past stop-by location, and the server device 30 may provide information content according to the stop-by period.

  In step S103, after the vehicle-mounted device 10 transmits the past stop location as uplink information to the radio device 10, the control unit 6 deletes the transmitted past stop location data from the storage unit 7. Also good. By erasing past stopover data that has been transmitted by the control unit 6 from the storage unit 6, it is possible to prevent the same past stopover data from being uplinked a plurality of times.

  In step S103 and step S203 of each embodiment, the information content included in the downlink information is determined based on the destination data. However, the present invention is not limited to such a form. For example, when the transit point is included in the uplink information in addition to the destination, the information providing system 1 may provide the information content regarding the route to the transit point or the vicinity of the transit point. Further, the server 30 does not calculate the route to the destination or waypoint, and outputs only the information content near the route on the vehicle-mounted device 10 side based on the route selected by the navigation function of the vehicle-mounted device 10. It is good also as such a setting. Specifically, when latitude and longitude information is included as a target point indicating a point providing information in ID10, latitude and longitude information in the vicinity of the route to the destination or route is determined by the navigation function, and the content matches. May be output only. As another specific example, when the latitude and longitude information for popping up the information content is included in the ID 20 and the route is near the latitude and longitude to be popped up, the pop-up may be output.

  Moreover, in this Embodiment, although the onboard equipment 10 shall have a navigation function, it may not be such a form. Furthermore, although the server device 30 can obtain information on a remote location via the server device 30, the present invention is not limited to such a configuration, and the data storage unit 33 may have all the information.

  In the present embodiment, the destination data is searched in step S204, and then the information content related to the past stopover data is transmitted in step S206. However, the present invention is not limited to such a form. For example, step S206 may be before step S204, or one of the steps may not be provided. Further, the information on the destination may be controlled so as to be output when it is within a predetermined distance range from the destination without being output immediately. Or the conditions to output may be defined. For example, the information content of a restaurant near that point may be displayed at 12:00 noon, or the information content regarding anti-slip of the vehicle 200 may be displayed when the outside air temperature is below freezing. . As described above, when the information content is output based on the set condition, the control unit 6 of the vehicle-mounted device 10 may control, or the server device 30 may transmit the downlink information. You may control. Or you may make it control by both, or you may make it include another program about which timing outputs in downlink information.

  In each of the above-described embodiments, restaurant information and the like are illustrated as an example of information content. However, the present invention is not limited to this, and any content may be used. For example, it may be information content such as sightseeing guidance, automobile repair advertisement, automobile parts advertisement, parking lot guidance, traffic jam guidance, and gasoline station guidance.

  Moreover, in each above-mentioned embodiment, although the vehicle equipment 10 shall receive information from the roadside radio | wireless apparatus 20 as a radio | wireless machine, if it is a radio | wireless machine which can transmit information, it is not restricted to such a form. It can be anything.

  In the above-described embodiment, the administrator of the roadside apparatus 20 may be a supplier that provides content information. In addition to this, for example, the administrator of the roadside apparatus 20 is not a provider that provides the content, but contracts with a provider that provides the content, and provides a person who operates the roadside apparatus 20, that is, a service. A person other than the person may install and manage the roadside apparatus 20.

  In addition, the roadside wireless device 20 performs processing for mediating exchange of information between the vehicle-mounted device 20 and the server device 30, but the roadside wireless device 20 includes the server device 30, and the roadside wireless device 20 includes the server device 30. It is good also as a form which performs all the processes.

  The functions of the constituent blocks included in the information providing system 1 according to the above-described embodiment may be realized in whole or in part by software, or at least part of it may be realized by hardware. For example, all or a part of the processing in the control unit 6 may be realized on a computer by one or a plurality of programs, and at least a part thereof may be realized by hardware.

  In addition, for example, a computer program for operating the vehicle-mounted device 10 as all or part of the apparatus can be read by a computer such as a memory card, a CD (compact disc), a DVD (digital versatile disk), or an MO (magnetic-optical). And stored in a separate recording medium, installed in another computer, for example, a mobile phone, an audio device, an electronic watch, etc., and operated as the vehicle-mounted device 10 or the steps performed by the vehicle-mounted device 10 are executed. Also good. Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer serving as the vehicle-mounted device 10 by being superimposed on a carrier wave, for example.

  In each embodiment, audio and video are output. However, the audio and video may be output by other means that can be recognized by the user through visual, auditory, olfactory, or tactile sensations. Specifically, for example, the vehicle-mounted device 10 that outputs information by vibration or light may be used. Moreover, it is good also as the onboard equipment 10 which outputs information combining two or more recognition methods. In addition, when information is output by video or the like, text information, still image information, video information, or a combination thereof may be output.
