  Next, a transaction performed in road-to-vehicle communication will be described with reference to FIG. In the transaction shown in FIG. 5, when the vehicle-mounted device 20 is turned on, the vehicle-mounted device 20 enters the communication area Z of the roadside apparatus 40 (hereinafter, this time of entry is referred to as “area-in”). The communication process of each part until the onboard equipment 20 moves out of the communication area Z (hereinafter, this time point is referred to as “area out”) is shown. Hereinafter, each step will be described.

  Step S100: The navigation unit 27 and the DSRC unit 21 that are part of the vehicle-mounted device 20 write client information data from the navigation unit 27 to the DSRC unit 21 when the power of the vehicle-mounted device 20 is turned on. The client information data includes information such as the type of content that can be played back by the vehicle-mounted device 20 in the communication area Z, and the content playback application installed in the vehicle-mounted device 20. In addition, language information that can be handled by the vehicle-mounted device 20, geodetic system information (Japanese or world geodetic system information) that the navigation unit 21 has, DRM (Digital Lights Management) that can be supported, and the display unit (display) that is installed The resolution, the amount of data that can be stored, and the like can be notified as supplement info information together with the client information data.

  Step S101: When a vehicle equipped with the vehicle-mounted device 20 is area-in, a DSRC connection process (for example, an authentication process in DSRC-SPF) is performed to establish communication of individual PUSH distribution between the roadside apparatus 40 and the vehicle-mounted device 20. Is done. Details of the DSRC connection process are omitted.

  Step S102: When the DSRC connection process is completed, the roadside apparatus 40 and the DSRC unit 21 perform DSRC connection notification to the center device 60 and the navigation unit 27, respectively.

  Step S103: The DSRC unit 21 transmits the client information data written by the navigation unit 27 to the roadside apparatus 40 (uplink). The roadside apparatus 40 can notify the center apparatus 60 of the client information data described above. This step S103 corresponds to a client information notification command.

  Step S104: The center device 60 uses the ASL-ID that can uniquely identify the vehicle-mounted device 20 itself based on the client information data notified in Step S103, and the function information that the vehicle-mounted device 20 has. , The content suitable for the vehicle-mounted device 20 is organized in a multi-content format and delivered to the roadside apparatus 40. Since the center device 60 knows the content that can be played back by the vehicle-mounted device 20 and the functions possessed by the vehicle-mounted device 20 from these client information data, the center device 60 can organize and distribute the optimum content. Moreover, since the center apparatus 60 can also acquire ID unique to the onboard equipment 20 by using the onboard equipment ID notification command or the like, the onboard equipment 20 can be specified. Further, for example, the center device 60 and / or the roadside device 40 can identify the vehicle 100 in which the vehicle-mounted device 20 is mounted by collating the customer DB and the like with the unique ID of the vehicle-mounted device 20. . The roadside apparatus 40 distributes the received content to the DSRC unit 21 of the vehicle-mounted device 20. The DSRC unit 21 distributes the content to the navigation unit 27. Note that the details of membership determination based on ASL-ID and the like are outside the scope of the present invention, and are therefore omitted.

  Step S105: The center device 60 confirms whether information is written in an uplink tag area (not shown), which is a specific storage unit described later, via the roadside wireless device 40 after the processing of Step S104. Therefore, the on-vehicle device 20 is periodically polled. If information is written in the uplink tag area by this polling, the information is acquired, and if not written, polling is further continued.

  Step S106: The navigation unit 27 discriminates the service provider from the content received in Step S104, and writes the uplink data for the service provider in the uplink tag area as a specific storage unit of the DSRC unit 21. . However, the navigation unit 27 does not write in the uplink tag area when there is no uplink data for the service provider or when the data is not a member of the service provider.

  Step S107: When information is written in the uplink tag area as a specific storage unit in Step S106, the DSRC unit 21 notifies (uplinks) the information to the roadside apparatus 40 (hereinafter, this step). The information to be processed at is called "uplink information"). The roadside apparatus 40 delivers the uplink information to the center apparatus 60.

  Step S108: After the process of step S107, the center device 60 periodically polls the uplink tag area as a specific storage unit through the roadside apparatus 40 for information. If the information of the uplink tag area as a specific storage unit is updated by this polling, the information is acquired, and if not updated, the polling is further continued.

  Step S109: When the center device 60 acquires the uplink information in step S107, based on the information, the center device 60 organizes the content suitable for the member preference in the multi-content format, and distributes it to the roadside wireless device 40 (hereinafter referred to as the roadside device 40) This process is called “downlink”). The roadside apparatus 40 reversely distributes the distributed content to the DSRC unit 21. The DSRC unit 21 analyzes the distributed content and transmits data to the navigation unit 27 as appropriate.

  Step S110: When the distribution of the content suitable for the preference data is completed, the center device 60 notifies the DSRC unit 21 to that effect and prompts the area out. This is because if one vehicle occupies the communication area for a long time, the service to other members cannot be provided. However, the notification for prompting the area out may not be performed.

  Next, a multi-content format exchanged on the above-described transaction will be described. The multi-content format constitutes a composite format configured for each 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. By using this multi-content format, it is possible to perform individual PUSH distribution in accordance with individual hobbies and preferences in DSRC communication that is PUSH distribution. In addition, the content provided in this multi-content format is once stored in the vehicle-mounted device 20 and can be played back when a specific condition is satisfied. Therefore, in order to send and receive information by DSRC communication, it is not possible to stay within the specific communication area, but by storing and storing the received information, information can be reproduced even outside the area. It becomes possible to do. Furthermore, by setting the reproduction timing of content such as regional information and advertisement information, it is possible to distribute information that meets the needs of the user. In addition, the multi-content format can reduce network traffic by reducing the amount of distribution data.

  FIG. 6 is a diagram showing a data group organized in a multi-content format (hereinafter, this data group is referred to as an “information group”). As illustrated in FIG. 6, reception data including a plurality of information groups from information group 1 to information group n is transmitted from the roadside apparatus 40 to the vehicle-mounted device 20. 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.

  Therefore, this multi-content format can play data in a specific location in conjunction with the car navigation function, and can guide to a specific location, in addition to playing data in the order distributed after reception. It has become. Furthermore, since this multi-content format can also store data in the vehicle-mounted device 20 that has received the distribution, the distribution data can be used even outside the communication area of the roadside apparatus 40.

  Further, since the in-vehicle device 20 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 20 to the center device 60. In addition, the multi-content format can take action history and viewing history of distributed content, including information on destinations and stopovers set in the vehicle-mounted device 20.

[Data structure of content information]
Next, the data structure of content information that is a multi-content format will be specifically described. FIG. 7 shows a display screen transition example displayed based on the content information included in the distribution data shown in FIG. FIG. 8 shows an example of the data format of the content information included in the distribution data shown in FIG.

  Each of the screens D1 to D6 illustrated in FIG. 7 is a screen that is displayed based on one piece of content information. As shown in FIG. 8, one piece of content information is composed of a file that can store information classified by ID00 to ID256, and stores necessary information according to the content to be provided. By using the data structure of the multi-content format, various operations of the distributed content can be defined. In addition, since the content to be distributed is composed of content assigned with a plurality of IDs, the configuration can be changed for each operation of the content.

  Here, main information necessary for the present embodiment among the information classified into ID00 to ID256 will be described.

  The “ID configuration information” classified as ID00 is an area for describing ID information included in the content to be distributed, as shown in FIG. The data format of ID = 00 has “information byte count” and “item presence / absence information” as shown in FIG. “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 20 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.

  As shown in FIG. 8, “operator information” classified as ID01 is information about a service provider that distributes the content. In the data format of ID = 01, as shown in FIG. 9, the service provider “service provider code”, “service provider utterance phonetic character string”, and “provider name display text” are provided. Etc. are included.

  The “content attribute information” classified as ID02 is information indicating the attribute of the content as shown in FIG. 8, and although not shown, for example, “information provider company code”, “ Information providing company name display text ”,“ information code ”for specifying content,“ information title display text ”indicating content content,“ preference data category information ”indicating content category, and the like are included. This content information has a hierarchical structure (for example, in FIG. 7, from the top, D1 → D2 → D3 → D4 → D5 → D6). In the present embodiment, each content is represented by an information code. The information hierarchy can be identified.

  As shown in FIGS. 8 and 10, “target point information” classified into ID 10 includes information about a point (referred to as a target point) where a service guided by the content is provided 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 voice data" for service voice guidance, information related to the content “URL information” indicating the address of the storage location of the Web page providing the information, “affiliated parking information” indicating the partner parking lot other than the target location, “icon image information” when displaying the target location on the map screen, etc. Is included.

  For example, in the content information for displaying the screen D6 of FIG. 7, all the information of ID01, 02, 04, and 10 is necessary, and therefore all the information of ID01, 02, 04, and 10 is stored. The content information for displaying each of the screens D1 to D5 in FIG. 7 includes “preference data category information” of ID02, “target point coordinate information” of ID10, “service name display text”, “URL information”, Since “partner parking information”, “icon image information” and the like are not necessary, these pieces of information are not stored.

  The “transition information” classified as ID 30 includes screen transition information and the like as shown in FIG. With this information, the screen transition as described above can be performed. The “detailed information” classified into the ID 40 includes a general-purpose area in which the detailed information can be written, as shown in FIGS. “Detailed information” is, for example, information related to the information distributed together with the ID 40 and accompanying information. Upon receiving the information (detailed information 1 to 8) described in the detailed information, the in-vehicle device 20 determines a copy control flag included in the detailed information and describes the content of the uplink member information 1 to 8 (described later). 13), and notifies the roadside apparatus 40 at the time of uplink. By distributing IDs such as unique benefits for each member, a maximum of eight unique information can be provided, so that the following member benefits can be distributed.

  For example, by determining an ID that defines a unique privilege for each distribution content and adding the ID to the content for distribution, the privilege can be distributed at the next area-in. Also, by writing data such as points, it is possible to confirm the user's points at the area-in. Further, even if cooperation between the plurality of center devices 60 is not established, addition or subtraction as a common point can be performed if an agreement “describe points in detailed information 1” is agreed between service business vehicles. Since the detailed information can be described in 16 bytes as will be described later, it is possible to give an encrypted ID that avoids tampering.

  As shown in FIGS. 8 and 12, “preference data” classified into ID 80 includes “number of information items in the same ID”, “preference data version information”, “preference data 1 to 127”, and the like. “Preference data” is data in which an action history of a user who uses the vehicle-mounted device 20 or a selected hobby / preference is stored or stored. About this preference data area | region, it is an area | region which can change a structure freely for every service provider. Since the content distribution desired by the user is performed based on the preference data, it is possible to improve the usage rate of the distributed content, and the user satisfaction of the vehicle-mounted device 20 can be improved.

  As for preference data, for example, if a maximum of 96 items can be set for each service provider (the remaining 31 items are unused), from general-purpose information providing services to detailed information providing services in specific fields. A wide range of content distribution is possible. As described above, version information is added to the preference data table, and the configuration of the preference data can be changed according to the intention of the service provider. The preference data table is uplink information from the vehicle-mounted device 20, and the center device 60 can obtain version information. Therefore, the center device 60 can update the preference data table stored in the vehicle-mounted device 20. . In addition, a predetermined number of items, for example, 12 items among the 96 preference data items may be used for public information providing service purposes as information items that are distributed as standard when providing information in DSRC communication.

  Next, an uplink data format performed from the vehicle-mounted device 20 to the roadside apparatus 40 will be described with reference to FIG. FIG. 13 is a diagram illustrating an uplink data format performed from the vehicle-mounted device 20 illustrated in FIG. 1 to the roadside apparatus 40.

  The uplink information shown in FIG. 13 includes “basic information”, “cumulative mileage”, “preference data table version”, “preference genre data”, “member information”, and the like. Note that the uplink information shown in FIG. 13 includes information that may be treated as personal information, so it is confirmed that the service provider has signed a contract with the user according to the user settings. It is desirable to perform uplink for the first time.

  The “basic information” illustrated in FIG. 13 includes the service provider code and the latitude / longitude information of “destination” and “route” set in the vehicle-mounted device 20. Based on the latitude / longitude information of the “destination” installed in the vehicle-mounted device 20, information on the destination local area is provided and information such as the information provision point of the destination local area (a place where DSRC communication is possible) is provided. Or can be distributed. Note that the latitude / longitude of the “route point” set in the vehicle-mounted device 20 can be registered up to five locations, and the route point is based on the latitude / longitude information of the route point installed in the vehicle-mounted device 20. It is possible to provide information in the direction and distribute information such as information provision points in the local area (location where DSRC communication is possible).

  In the “cumulative travel distance” illustrated in FIG. 13, a travel distance from when the vehicle-mounted device 20 is mounted on the vehicle 100 is stored. An item for storing the travel distance from the start of travel of the vehicle 100 may be provided. Since the “preference data table version” indicates the version of the preference data stored / uplinked by the vehicle-mounted device 20, it can be used for the analysis of the preference data linked to the uplink. In addition, when updating the preference data table, the roadside apparatus 40 preferably reflects the setting value of the preference data of the old version on the setting value of the preference data table of the new version in order to reduce the user's trouble. .

  In the “preference genre data” shown in FIG. 13, a preference data table of up to 96 items (of which 12 items are reserved for public information providing services) can be freely set by the service provider as described above. Depending on the business content of the service provider, it becomes possible to provide information that is subdivided according to the user's preference, so that the reproduction rate of the distributed information can be improved. This table is created by the service provider and transmitted from the roadside apparatus 40.

  In the “member information” shown in FIG. 13, basically, the same contents as the detailed information 1 to 8 distributed with the downlink ID = 40 can be recorded in the member information 1 to 8. In the present embodiment, distribution of member benefits is realized by writing and storing member privileges or coupon information included in content distributed from the center device 60 in the storage area of the member information 1 to 8. Yes. A detailed flow of the process for distributing the member benefits and the like, the process for using the member privileges, and the storage process will be described later.

  The vehicle-mounted device 20 may describe the latest information code that can be stored in the “member information 8” field in the uplink data format. In this case, when the communication is disconnected, the center device 60 can read the “member information 8” to understand the information stored in the vehicle-mounted device 20, and can therefore distribute the information from the subsequent information. Even when communication is interrupted for some reason when receiving information distribution, the user can receive the information distribution from the continuation. Therefore, it is possible to reduce a time loss due to communication interruption. In addition to the items described above, the uplink information may include “past stop information” and “advertisement viewing history information” not shown.

  Next, a member privilege distribution process performed by the roadside apparatus 40 in the information distribution system 10 having the above-described configuration will be described with reference to FIG. FIG. 14 is a flowchart showing a process in which the roadside apparatus 40 shown in FIG. 1 distributes member benefits.

  START: The roadside apparatus 40 starts a member privilege distribution process when a predetermined DSRC communication connection process and a member authentication process are completed after the vehicle-mounted device 20 is in the area (in steps S100 to S104 shown in FIG. 5). Equivalent). In the member authentication process, when it is determined that the user is a member, it is further determined whether or not the user (member) can receive the privilege, and the privilege distribution process after step S120 is performed.

  Step S120: The roadside apparatus 40 determines whether or not uplink information from the vehicle-mounted device 20 has been received. The roadside apparatus 40 performs the process of step S121 when received, and if not, periodically polls the vehicle-mounted device 20 and continues the determination process of step S120 (shown in FIG. 5). Equivalent to step S105).

  Step S121: When the roadside apparatus 40 receives the uplink information from the vehicle-mounted device 20 in step S120, the roadside apparatus 40 acquires the service provider code included in the uplink information and proceeds to step S122 (FIG. Equivalent to step S107 shown in FIG.

  Step S122: The roadside apparatus 40 determines whether there is privilege information (predetermined information) such as coupon information from the service provider code. When there is privilege information such as coupon information, center device 60 performs the process of step S123. Specifically, privilege information (specific information that can receive a privilege) such as target coupon information is written in ID = 40 of the downlink data together with the ID. If there is no privilege information such as coupon information, the process of step S124 is performed. The roadside apparatus 40 further distributes the content in which privilege information such as coupon information is written to the data of ID 40 to the roadside apparatus 40. As a result, the member privilege distribution process is terminated (END). The distributed content is distributed from the roadside apparatus 40 to the vehicle-mounted device 20. For example, privilege information such as coupon information is written in the detailed information 1 shown in FIG.

  Step S124: When there is no privilege information such as coupon information provided by the authenticated service provider, the roadside apparatus 40 ends the determination process of step S122 and ends the member privilege distribution process (END).

  As described above, the roadside apparatus 40 is set as a dedicated area for writing privilege information such as coupon information in any of the writing areas of the detailed information 1 to 8 distributed as ID = 40. Distribution of benefits and the like can be performed.

  Next, the member privilege acquisition process and use process in the vehicle-mounted device 20 will be described with reference to FIG. FIG. 15 is a flowchart showing the member privilege acquisition process and use process in the information distribution system 10 shown in FIG.

  START: The vehicle-mounted device 20 starts the member privilege acquisition process and the use process when the downlink from the center device 60 is started (corresponding to step S109 shown in FIG. 5).

  Step S130: When the in-vehicle device 20 includes the ID 40 in the downlink frame, whether or not privilege information (specific information that can receive the privilege) such as coupon information is written in the detailed information. Determine whether. The vehicle-mounted device 20 performs the process of step S131 when privilege information such as coupon information is not written, and performs the process of step S132 when it is written. For example, if information is written in the “detailed information 1” column shown in FIG. 11, it is determined that there is privilege information such as coupon information, and if it is not written, there is no privilege information such as coupon information. judge.

  Step S131: The vehicle-mounted device 20 ends the determination process of Step S130, and ends the member privilege acquisition process and the use process (END).

  Step S132: The vehicle-mounted device 20 determines whether to use a privilege. Specifically, a screen or a button for confirming whether or not the privilege can be used is generated on the display unit 33, and the user is allowed to select whether or not the privilege can be used. If the user does not use, the process of step S133 is performed. If the user does not use, the process of step S134 is performed.

  Step S133: The vehicle-mounted device 20 writes a specific code (predetermined information / specific information that can receive a privilege) to a storage unit such as the memory unit 25, and ends the member privilege acquisition process and the use process ( END).

  Step S134: The vehicle-mounted device 20 ends the determination process of Step S131 (END). In addition, the process based on predetermined | prescribed privilege information is performed by the notification which uses a privilege to the center apparatus 60, and the acquisition process and utilization process of a member privilege are complete | finished.

  As described above, the vehicle-mounted device 20 determines whether or not there is privilege information such as coupon information by determining whether or not the information is written as predetermined information in a specific area of the distributed content, and uses the information. Let the user confirm the intention. And when not using at that time, by writing as a specific code (specific information which can receive a privilege) in a specific memory | storage part etc., the presence or absence of privilege information, such as the coupon information, at the time of an uplink next time Notification can be made to the wireless device 40 side.

  Next, a member privilege distribution process in the case where privileges can be shared between different service providers will be described with reference to FIG. FIG. 16 is a flowchart showing a member privilege distribution process in the case where a privilege can be commonly used among different service providers in the information distribution system 10 shown in FIG. Note that the steps from START to step S142 in the flowchart shown in FIG. 16 are the same as the processing from START to step S122 in the flowchart shown in FIG. 14, and thus the description from START to step S142 is omitted.

  Step S143: The roadside apparatus 40 determines whether or not a privilege can be commonly used among different service providers. For example, the code of the business operator A, which is a different service business operator, is “123456...” And the business operator code of the business B is “123756. For example, “123” is used as a common code). When set in this way, it is determined that the member privilege information among these service providers can be used in common. If it is determined that the privilege cannot be used in common, the process of step S146 is performed. If the privilege is commonly used, the process of step S145 is performed.

  Step S145: The roadside apparatus 40 transmits information in which privilege information such as coupon information (specific information that can receive the privilege) is written to the vehicle-mounted device 20 in the common detailed information column of the ID 40, and the member privilege. The distribution process is terminated (END). For example, in the case of content distributed by the A company, a coupon is applied to the common detailed information area of ID A = 40 of the A company and the B company (for example, when the detailed information 2 shown in FIG. 11 is used as the common area). Benefit information such as information is written.

  Step S146: The roadside apparatus 40 transmits information in which privilege information such as coupon information is written in the detailed information column of the ID 40 of the target business operator to the vehicle-mounted device 20, and ends the member privilege distribution process ( END). For example, in the case of distribution content from a C company having a different business code from the first three digits of the A company and B company, the column of detailed information for C company ID = 40 as usual ( For example, privilege information such as coupon information is written in the detailed information 1) shown in FIG.

  Thus, the roadside apparatus 40 writes the privilege information such as normal coupon information in the writing area of the detailed information 1 to 8 distributed as ID = 40 (for example, the detailed information 1 shown in FIG. 11), An area for writing privilege information such as coupon information that can be used in common (an area for detailed information other than the detailed information 1 shown in FIG. 11, for example, detailed information 2) is provided, and discrimination based on the operator code is performed. Thus, it is possible to determine whether or not the service can be commonly used among different service providers, and to distribute member benefits that can be used between different service providers.

  Next, a member benefit acquisition process and a use process when benefits can be commonly used among different service providers will be described with reference to FIG. FIG. 17 is a flowchart showing a member privilege acquisition process and a use process when a privilege can be commonly used among different service providers in the information distribution system 10 shown in FIG. 1. Note that the processing from START to step S132 in the flowchart shown in FIG. 15 and the processing from START to step S152 in the flowchart shown in FIG. 17 are the same processing, so the description from START to step S152 is omitted.

  Step S153: The vehicle-mounted device 20 writes privilege information such as coupon information (specific information that can receive the privilege) in a storage unit such as the memory unit 25, and ends the member privilege acquisition process and the use process ( END). In this way, privilege information is written in an area that is commonly used by a plurality of service providers that can be used in common, so that inconsistency of privilege information does not occur.

  Step S154: If the determination process in Step S152 is YES, the vehicle-mounted device 20 performs a process based on a predetermined privilege, and ends the member privilege acquisition process and the use process (END). Specifically, a specific storage unit for each different service provider is referred to, and the presence / absence of corresponding privilege information is checked.

  In this way, the vehicle-mounted device 20 determines whether or not specific information that can receive a privilege is written in a specific area of the distributed content, so that a coupon that can be used between different operators is also provided. The presence or absence of privilege information such as information can be determined. And when a user does not use at that time, by writing in a common memory | storage part etc., the presence or absence of privilege information, such as the coupon information, can be notified to the roadside apparatus 40 side at the time of an uplink next time.

  The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications and changes can be made without departing from the scope of the invention. is there.

  For example, in the said embodiment, the coupon which can receive a service and goods as a privilege and the coupon which can receive a specific service and goods for free are assumed. In addition to this, for example, a coupon for distributing a free parking ticket, an extended ticket at the time of parking, or the like may be adopted. Further, points that can be used at the next visit may be added, or points may be subtracted according to use. Furthermore, as the predetermined content other than the privilege, various kinds of latest information such as “video information that can be provided by the latest rental” in the case where the service provider is a rental company such as a video can be cited.

  Moreover, in the said embodiment, the center apparatus 60 and the roadside radio | wireless apparatus 40 are isolate | separated. In addition to this, for example, the roadside apparatus 40 may have some or all of the functions of the center apparatus 60.
