The default content information for members is, for example, Welcom screen information indicating the start of distribution of content information.

  Moreover, the control part 31 polls with respect to the onboard equipment 10 regularly (step S8, S11), and requests | requires transmission of the uplink information written in the uplink information storage area M. FIG.

  When the content information is received via the roadside apparatus 20, the control unit 4 of the vehicle-mounted device 10 is included in the provider code included in the received content information and the uplink information stored in the storage unit 1f. By collating with the contractor's provider code, it is determined whether or not the distribution provider that distributed the received content information is the contracted provider. When it is determined that the distribution company that distributed the received content information is not a contracted company (step S9; NO), the control unit 4 responds to reception of message information that notifies the end of distribution from the center device 30. Then, it checks whether or not all the content information is complete, whether or not the received content information data is all normal (step S40), and stores the received content information in the storage unit 1f (step S41). And the control part 4 reads the content information preserve | saved at the memory | storage part 1f according to the user's instruction | indication input via the input part 1d, and reproduces | regenerates by the display part 1e or the audio | voice output part 1g (step S42). ). The content information can be displayed and reproduced even after the vehicle-mounted device 10 is out of the area.

  On the other hand, if it is determined that the distribution company in the center device 30 with which communication has been established is a contracted company (step S9; YES), the control unit 4 displays uplink information corresponding to the company code of the distribution company. The data is read from the storage unit 1f and written to the uplink information storage area M (step S10).

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area M to the roadside radio device 20 in response to polling from the center device 30. To the center device 30 (step S12).

In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 transmits an uplink information release request to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step). S13). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 deletes the uplink information written in the uplink information storage area M in step S10, and stores the storage unit. Of the past stopover information, reception / playback history information, and member information stored in If, the information written in the uplink information storage area M in step S10 is deleted (step S14).
It should be noted that the uplink past drop-in place information, reception / playback history information, and member information stored in the storage unit 1f are stored with a flag indicating that they have been uplinked without being deleted. May be managed. In this case, when the uplink information is written in the uplink information storage area M next time, the control unit 4 performs control so that information that has been uplinked and has the same content is not written.

  When receiving the uplink information by the communication unit 35, the control unit 31 of the center apparatus refers to the member information of the received uplink information and determines whether or not the received uplink information includes comment information. (Step S15). If it is determined that comment information is included in the received uplink information (step S15; YES), the control unit 31 executes a privilege addition process (step S16).

In FIG. 12, the privilege addition process performed by the control part 31 of the center apparatus 30 in step S16 is shown.
In the privilege addition process, the control unit 31 acquires an information code and comment information (comment character string) from the received member information of the uplink information (step S101), and registers the acquired information in the comment DB 342 (step S102). .

Next, the control unit 31 adds the number of points in the “acquisition points” field corresponding to the on-board unit ID of the on-board unit 10 of the uplink information transmission source in the member information DB 341 (step S103), and adds (gives) The notification information of the number of privilege points is transmitted to the vehicle-mounted device 10 through the communication unit 35 (step S104), and this process is terminated.
For example, the number of privilege points corresponding to the number of comment information and the number of characters of the comment included in the received uplink information is determined in advance, and the control unit 31 stores the uplink information transmission source vehicle-mounted device 10 in the member information DB 341. The number of points corresponding to the number of comment information included in the received uplink information and the number of characters of the comment is added to the “acquired point” field corresponding to the vehicle-mounted device ID. When a comment is written in the member information 1 to 8 included in the uplink information, the information code of the content information that is the input target of the comment is written in the first upper predetermined byte (here, 5 bytes), and the next Since Byte includes a delimiter “,” between the information code and the comment character string (see FIG. 16), the delimiter included in the upper predetermined bytes of the member information 1 to 8 is counted. Thus, the number of comment information included in the member information can be acquired.
The notification information of the number of privilege points is transmitted as content information for displaying a notification screen on which a message such as “XX points have been added” is displayed, for example. In addition, privilege information, such as coupon information according to the privilege point, may be described in the detailed information of ID 40 of the content information on the notification screen and transmitted to the vehicle-mounted device 10.

Further, the control unit 31 of the center device 30 organizes content information to be distributed based on the received uplink information, and distributes the content information to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step S17).
In step S17, for example, content that distributes content information or the like classified into genre items preferred by the user among content information stored in the storage unit 34 with reference to preference genre data or the like of the received uplink information. And the corresponding content information is read from the storage unit 34 and sequentially delivered to the vehicle-mounted device 10.

  When the distribution of the content information is completed, the control unit 31 of the center device 30 generates message information that notifies the end of the distribution, and transmits the message information to the in-vehicle device 10 via the roadside wireless device 20 by the communication unit 35 (step S18).

  In the vehicle-mounted device 10, when the content information distributed from the center device 30 and the distribution end notification are received via the roadside wireless device 20, the control unit 4 of the vehicle-mounted device 10 has received whether or not all the content information is complete. The content information data is checked to see if it is all normal (step S19), and the received content information is stored in the storage unit 1f and the reception history is stored in the storage unit 1f (step S20). Specifically, the reception information code of the received content information is written in the uplink information corresponding to the provider code stored in the storage unit 1f.

When the content information is stored, the control unit 4 executes a content reproduction process in accordance with a user instruction input by the input unit 1d (step S21).
FIG. 13 shows the content reproduction process executed by the control unit 4 of the vehicle-mounted device 10 in step S21.
In the content reproduction process, the control unit 4 first reads one piece of received content information (step S201). At the start of processing, the content information of the highest hierarchy among the received content information is searched and read out.

  Next, the control unit 4 creates a “comment input” button B1 for the user to input an instruction to write a comment on the content (step S202), and reproduces the content information including the “comment input” button B1 (step S202). S203). Specifically, a screen is displayed on the display unit 1e based on the “display character data” and “display image data” of the read content information, and “comment input” is displayed at a predetermined position on the displayed screen. Button B1 is displayed. The creation of the “comment input” button B1 may be started after the content information is reproduced after the content information is reproduced and triggered by a touch instruction on any screen G1. Further, the voice output unit 1g outputs a voice based on the “phonetic character string data”. FIG. 14 shows an example of the screen G1 displayed on the display unit 1e in step S203.

  Next, the control unit 4 stores the reproduction history by setting “1” in the reproduction identification flag corresponding to the information code of the content information in the uplink information stored in the storage unit 1f (step S204).

  When the “comment input” button B1 is pressed by the input unit 1d and an instruction to write a comment is input (step S205; YES), the control unit 4 displays the input interface screen G2 on the display unit 1e (step S206). .

  FIG. 15 shows an example of the input interface screen G2 displayed in step S206. As shown in FIG. 15, for example, an input interface screen G2 configured by a keyboard or the like for inputting comment information is displayed.

  When comment information is input by the input unit 1d according to the input interface screen G2 (step S207), the control unit 4 centers the information code of the content information reproduced in step S203 and the input comment information (comment character string). The information is stored in the storage unit 1f as the member information of the uplink information about the provider of the provider code notified from the device 30 (step S208), and the process proceeds to step S209.

  If comment writing is not instructed by the input unit 1d in step S205 (step S205; NO), the process proceeds to step S209.

  In step S209, the control unit 4 determines whether or not the input unit 1d has instructed the reproduction of the next content information. If it is determined that the reproduction of the next content information has been instructed (step S209; YES), the process returns to step S201, and the processes after step S201 are repeatedly executed. If the input unit 1d determines that the reproduction of the next content information is not instructed within a predetermined time or the user instructs the end of the reproduction (step S209; NO), the control unit 4 ends this process. .

  On the other hand, the control unit 31 of the center device 30 periodically polls the vehicle-mounted device 10 via the roadside device 20 by the communication unit 35 (steps S22 and S24 in FIG. 11), and the uplink information storage area M Requests transmission of uplink information written in.

  When the content reproduction process ends, the control unit 4 of the vehicle-mounted device 10 reads the uplink information corresponding to the business operator code notified from the center device 30 from the storage unit 1f and writes it in the uplink information storage area M (step S23). ). By this step S23, the comment information written in the content reproduction process is written in the uplink information storage area M.

  FIG. 16 shows an example of data writing to the member information areas 1 to 8 in the uplink information storage area M. As shown in FIG. 16, first, the information code of the content information to be commented is written in the upper predetermined bytes (here, 5 bytes) of the free space of the member information 1 to 8, and then the delimiter “,” Is written, and the character information of the comment is written following the delimiter. When there are many characters, it is written across the next member information column. In the member information 1 to 8, only a total of 128 bytes of information can be written. By transmitting uplink information to the center device 30 once, only the information of the maximum 128 bytes including the information code and the comment information can be stored in the center device 30. However, when there are a large number of characters, it is possible to cope with comment information with a large number of characters by transmitting the uplink information to the center device 30 a plurality of times.

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area M to the roadside radio device 20 in response to polling from the center device 30. To the center device 30 (step S25).

  In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 transmits an uplink information release request to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step). S26). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 deletes the uplink information written in the uplink information storage area M in step S23, and stores the storage unit. Of the past drop-in place information, reception / reproduction history information, and member information stored in 1f, the information written in the uplink information storage area M in step S23 is deleted (step S27).

  When the uplink information is received by the communication unit 35, the control unit 31 of the center apparatus 30 refers to the member information of the received uplink information and determines whether or not comment information is included in the uplink information ( Step S28). If it is determined that comment information is included in the received uplink information (step S28; YES), the control unit 31 executes a privilege addition process shown in FIG. 12 (step S29). Here, in the case of comment information with a large number of characters, the entire text of the comment is transmitted by transmitting uplink information a plurality of times, but one information code is added to the beginning of one comment information as shown in FIG. Therefore, as described in step S16, when the privilege points are added according to the number of comment information of the user, the privilege points without duplication can be obtained by counting the number of information codes (or the number of delimiters) included in the uplink information. Can be added. For example, if the comment information received this time is cut off in the middle, points will be added in this privilege addition process, but the points will not be included in the comment information that follows this time when receiving the next time Points are not added. Note that an identifier (for example, “;”) indicating that the comment has ended may be sent at the end of the comment information character string, and bonus points may be added when all the comment information is received.

  Moreover, the control part 31 of the center apparatus 30 performs polling with respect to the onboard equipment 10 via the roadside radio | wireless apparatus 20 by the communication part 35 regularly (step S30, S32), and writes in the uplink information storage area M Request transmission of the uplink information.

  When the deletion of the uplink information in step S27 is completed, the control unit 4 of the vehicle-mounted device 10 reads the uplink information corresponding to the business operator code notified from the center device 30 from the storage unit 1f, and the uplink information storage area M (Step S31). By this step S31, when the comment information written in the content reproduction process cannot be transmitted in step S23, the continued comment information not yet transmitted is written in the uplink information storage area M.

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area M to the roadside radio device 20 in response to polling from the center device 30. To the center device 30 (step S33).

  In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 transmits an uplink information release request to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step). S34). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 deletes the uplink information written in the uplink information storage area M in step S31, and stores the storage unit. Of the past drop-in place information, reception / reproduction history information, and member information stored in 1f, the information written in the uplink information storage area M in step S31 is deleted (step S35).

  When the uplink information is received by the communication unit 35, the control unit 31 of the center apparatus 30 refers to the member information of the received uplink information and determines whether or not comment information is included in the uplink information ( Step S36). If it is determined that comment information is included in the received uplink information (step S36; YES), the control unit 31 executes a privilege addition process shown in FIG. 12 (step S37).

  Thereafter, when the vehicle-mounted device 10 moves out of the mutual communication area Z (area out), the processing of steps S30 to S37 is repeatedly executed until communication with the roadside apparatus 20 is interrupted for a certain time or longer. When the on-vehicle device 10 moves out of the mutual communication area Z (area out) and communication is interrupted for a certain time or more, a series of processing of content information distribution ends.

  As described above, according to the first embodiment, when the vehicle-mounted device 10 reproduces the content information received from the center device 30, the input unit 1d is instructed to input a comment about the content information. Then, the input interface screen G2 on which the keyboard for inputting the comment information about the content information is displayed is displayed on the display unit 1e, and the input comment information and the content information that is the input target of the comment information are displayed. An information code for identification is included in the member information of the uplink information transmitted to the center device 30 and transmitted to the center device 30.

  Therefore, the user of the vehicle-mounted device can transmit comment information regarding the received content information from the vehicle-mounted device to the center device that distributes the content information.

  In addition, the center device 30 determines whether or not the comment information is included in the uplink information received from the vehicle-mounted device 10, and when the comment information is included, comment information is sent to the user of the source vehicle-mounted device 10. Is added to the in-vehicle device 10.

  Therefore, it becomes possible to give a privilege point to the user who has input the comment information with respect to the content information, and the distribution company can improve the service to the members.

  Further, the vehicle-mounted device 10 stores the input comment information in the storage unit 1f, and when the polling is newly received after receiving the uplink information release request previously transmitted from the center device 30, the storage unit Uplink information including comment information subsequent to the transmitted comment information stored in 1 f is transmitted to the center apparatus 30 by the DSRC unit 3.

Therefore, even if comment information with a large number of characters is input, it can be transmitted to the center device 30.
The received content information can be reproduced outside the mutual communication area Z. When the content reproduction process shown in FIG. 13 is executed outside the mutual communication area Z and the comment information is input, the input comment information is stored in the storage unit 1f in association with the information code. The comment information inputted at the time is sent to the member information 1-8 of the uplink information and transmitted.
In the above embodiment, a comment can be input to the content information desired by the user from all the content information. However, the content information to be commented is determined in advance by the center device 30 and the comment input target. A flag indicating that may be set in the content information and transmitted. And in the onboard equipment 10, you may make it display comment input button B1 with respect to the content information of comment input object. In this way, the distribution company can collect the comment information only for the content information desired to be commented.

  Further, in the above embodiment, the case where a sentence is input as comment information has been described as an example. However, a code corresponding to a comment is included in the display image data of ID10, phonogram data, voice data, etc. The code may be entered by the user. For example, when the content shown in FIG. 14 is being displayed, the user outputs a voice saying “Please enter a comment that seems to be the closest to you. A was very helpful, B was not interesting, and C was not useful.” For example, comment information may be input by inputting “A” and a comment as a selection branch. Alternatively, an evaluation point may be input. For example, the content of FIG. 14 may be output as a voice “Please input an evaluation score for this content” and the user may input “80”. In the case where the content information is display image data, a sentence with contents for prompting selection and evaluation points is displayed on the screen.

[Second Embodiment]
The second embodiment according to the present invention will be described below.
First, the configuration of the second embodiment will be described.
Since the configuration of each device and the data configuration of content information and uplink information in the second embodiment are substantially the same as those in the first embodiment, the description is incorporated and different parts from the first embodiment. explain.

  In the second embodiment, as described in the first embodiment, the storage unit 34 of the center device 30 stores a program executed by the control unit 31, various data necessary for executing the program, and content information. In addition to storing the provider code individually assigned to the distributor, the content information to be distributed, and the member DB 341, the questionnaire DB 343 is stored. The questionnaire DB 343 is a database that stores information about a questionnaire conducted for the user of the vehicle-mounted device 10.

  FIG. 17 shows a data storage example of the questionnaire DB 343. As shown in FIG. 17, the questionnaire DB 343 has a “record NO.” Field, a “questionnaire applicable information code” field, a “questionnaire screen information code” field, a “YES” field, a “NO” field, and the like. Are stored as one record in association with each other. The “record No.” field is an area for storing a number assigned to identify a record in the questionnaire DB 343. The “questionnable information code” field is an area for storing an information code of content information to be subjected to the questionnaire. The “questionnaire screen information code” field is an area for storing an information code of content information (questionnaire screen content information) to be transmitted to a user who has reproduced the content information to be surveyed. The “YES” field is an area for storing the number of people who answered “YES” to the questionnaire on the questionnaire screen. The “NO” field is an area for storing the number of people who answered “NO” to the questionnaire on the questionnaire screen.

  The center device 30 and the vehicle-mounted device 10 are equipped with a communication function based on the vehicle-mounted device response application defined by ITS FORM RC-004 at the ITS information communication system promotion conference. It is possible to notify a confirmation request command (details will be described later) from the device 30 to the vehicle-mounted device 10, or to transmit a confirmation response command to the confirmation request command in the vehicle-mounted device 10 to the center device 30.

  Next, the operation | movement between each apparatus of the information delivery system 100 in 2nd Embodiment is demonstrated.

18 to 19 are flowcharts for explaining the processing flow in the center device 30, the roadside wireless device 20, the DSRC unit 3 and the control unit 4 of the vehicle-mounted device 10 when content information is distributed.
As shown in FIG. 18, when the engine of the vehicle C is started and the power of the vehicle-mounted device 10 is turned on (step T1), the control unit 4 generates characteristic information of the vehicle-mounted device 10 and updates the storage unit 3c. Write to the link information storage area M (step T2). The characteristic information is obtained by the control unit 4 inquiring about each item such as the display unit 1e about items that have been negotiated with the center device 30 in advance, or by reading information stored in the storage unit 1f in advance. get. Then, the control unit 4 encodes the acquired information and writes the code in a corresponding area of the uplink information storage area M. Actually, control information for instructing writing is output to the DSRC control unit 3a, and the DSRC control unit 3a writes the information to the uplink information storage area M.

  Thereafter, when the vehicle C starts traveling and enters the mutual communication area Z of the roadside apparatus 20 (area-in), the roadside apparatus 20 detects the vehicle C and connects to the DSRC unit 3 of the vehicle-mounted device 10 through DSRC communication. Processing is started (steps T3a and T3b). That is, when a DSRC radio wave is transmitted and a response from the vehicle-mounted device 10 is obtained, a communication path is established. When the communication path is established, the roadside apparatus 20 transmits notification information indicating that the connection is completed to the center apparatus 30 (step T4a). On the other hand, the DSRC unit 3 of the vehicle-mounted device 10 outputs notification information indicating that the connection is completed to the control unit 4 (step T4b).

Next, the DSRC unit 3 transmits the characteristic information written in the uplink information storage area M to the roadside apparatus 20 (step T5). The characteristic information is transmitted to the center apparatus 30 via the roadside apparatus 20.
In the center apparatus 30, when the characteristic information is received by the communication unit 35, the control unit 31 determines whether the user of the vehicle-mounted device 10 is a member of the distribution service based on the vehicle-mounted device ID included in the received characteristic information. (Step T6).

  The control unit 31 of the center device 30 does not match the received vehicle-mounted device ID among all the vehicle-mounted device IDs of the information distribution service registered in the member information DB 341, and the user of the vehicle-mounted device 10 is a non-member. (Step T6; NO), the content information for non-members is distributed to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step T32). When the distribution is completed, the control unit 31 of the center apparatus 30 generates message information for notifying the end of distribution and transmits the message information to the vehicle-mounted device 10 (step S33), and the process in the center apparatus 30 is completed. Non-member content information is information on general contents such as public advertisement information such as train delay information and tax payment notice information.

  On the other hand, when the vehicle-mounted device ID that matches the received vehicle-mounted device ID is registered in the member information DB 341 and the user of the vehicle-mounted device 10 is determined to be a member (step T6; YES), the control unit 31 of the center device 30 The default content information for the member is transmitted to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step T7). The default content information for members is, for example, Welcom screen information indicating the start of distribution of content information.

  Moreover, the control part 31 polls with respect to the onboard equipment 10 regularly (step T8, T11), and requests | requires the uplink information written in the uplink information storage area M. FIG.

  When the content information is received via the roadside apparatus 20, the control unit 4 of the vehicle-mounted device 10 is included in the provider code included in the received content information and the uplink information stored in the storage unit 1f. By collating with the provider code, it is determined whether or not the distribution provider that has distributed the received content information is a contracted provider. When it is determined that the distribution company that distributed the received content information is not a contracted company (step T9; NO), the control unit 4 responds to reception of message information that notifies the end of distribution from the center device 30. Then, it checks whether all the content information is complete, whether the received content information data is all normal (step T34), and stores the received content information in the storage unit 1f (step T35). And the control part 4 reads the content information preserve | saved at the memory | storage part 1f according to the user's instruction | indication input via the input part 1d, and reproduces | regenerates by the display part 1e or the audio | voice output part 1g (step T36). ). The content information can be displayed and reproduced even after the vehicle-mounted device 10 is out of the area.

  On the other hand, if it is determined that the distribution company that has distributed the received content information is a contracted company (step T9; YES), the control unit 4 determines the uplink information corresponding to the company code of the distribution company. Read from the storage unit 1f and write to the uplink information storage area M (step T10).

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area M to the roadside radio device 20 in response to polling from the center device 30. To the center device 30 (step T12).

In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 transmits an uplink information release request to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step). T13). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 deletes the uplink information written in the uplink information storage area M in step T10, and stores the storage unit. The information written in the uplink information storage area M in step T10 is deleted from the past stop-in place information, reception / reproduction history information, and member information stored in 1f (step T14).
It should be noted that the uplink past drop-in place information, reception / playback history information, and member information stored in the storage unit 1f are stored with a flag indicating that they have been uplinked without being deleted. May be managed. In this case, when the uplink information is written in the uplink information storage area M next time, the control unit 4 performs control so that information that has been uplinked and has the same content is not written.

  When receiving the uplink information by the communication unit 35, the control unit 31 of the center device refers to the reception / reproduction history information of the received uplink information and determines whether or not the information code corresponding to the questionnaire exists in the reproduction history. (Step T15 in FIG. 19). Specifically, an information code (referred to as a reproduced information code) corresponding to the reproduction identification flag “1” included in the reception / reproduction history information is extracted, and each of the extracted reproduced information codes is stored in the questionnaire DB 343. The corresponding information code is extracted as the questionnaire corresponding information code included in the reproduction history.

  When determining that the information code corresponding to the questionnaire does not exist in the reproduction history (step T15; NO), the control unit 4 skips the processing after step T16 and proceeds to the processing of step T27.

  When it is determined that the information code corresponding to the questionnaire exists in the reproduction history (step T15; YES), the control unit 31 selects a questionnaire screen corresponding to the information code corresponding to the questionnaire existing in the reproduction history (more specifically, the questionnaire screen is displayed). Content information to be displayed) is read from the storage unit 34 and transmitted to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step T16). FIG. 20A shows an example of a questionnaire screen transmitted to the vehicle-mounted device 10 in step T16. As shown in FIG. 20 (a), a questionnaire question and the like are described on the questionnaire screen. In the content information for displaying the questionnaire screen transmitted in step T16, a code indicating immediate reproduction is stored as “immediate reproduction / accumulation code” of ID03, and the control unit 4 is received from the center device 30. The questionnaire screen is displayed on the display unit 1e.

Moreover, the control part 31 of the center apparatus 30 is a confirmation request command for requesting a confirmation response of YES / NO in the vehicle-mounted device 10 stipulated by ITS FORM RC-004 in the ITS information communication system promotion meeting. Is transmitted to the vehicle-mounted device 10 by the communication unit 35 (step T19). The confirmation request command includes information that prompts the user to output an interface for inputting a YES / NO response.
When the confirmation request command from the center apparatus 30 is received by the DSRC unit 3, the control unit 4 displays the input button B2 for YES / NO response on the questionnaire screen based on the information included in the confirmation request command. (Step T20).

  FIG. 20B shows an example of a questionnaire screen on which a response input button B2 is displayed. The input button B2 is superimposed on a part of the screen so that the questionnaire screen does not disappear, or the questionnaire screen can be confirmed through the watermark. The response of YES / NO may be input by detecting the pressing of the input button B2 with a touch panel, or by preparing a mechanical YES key, NO key, etc. in advance. You may make it input by.

  In the vehicle-mounted device 10, when any of the input buttons B2 for response is pressed by the input unit 1d and a response of YES or NO to the question on the questionnaire screen is input (step T21), the control unit 4 responds to the input. The confirmation response command is generated and transmitted to the center apparatus 30 via the DSRC 3 and the roadside apparatus 20 (step T22).

  When the confirmation response command is received by the communication unit 35, the control unit 31 of the center apparatus 30 adds up the questionnaire responses based on the received confirmation response command (step T23). For example, when the response “YES” is included in the confirmation response command, the control unit 31 sets 1 to the numerical value of the “YES” field of the record having the information code of the questionnaire screen transmitted in step T16 in the questionnaire DB 343. If the confirmation response command includes a “NO” response, the control unit 31 adds 1 to the numerical value of the “NO” field of the record having the information code of the questionnaire screen transmitted in step T16 in the questionnaire DB 343. Is added. Further, when the center device 30 transmits a confirmation request command to the vehicle-mounted device 10, the center device 30 can instruct a time from when the vehicle-mounted device 10 receives the command until a confirmation response is received. If the confirmation response command is not received, it is determined that the timeout has occurred and the questionnaire is not counted, or the answer is not counted.

Next, the control unit 31 adds privilege points by adding a predetermined number to the value of the “acquisition points” field of the record corresponding to the on-vehicle device ID of the on-vehicle device 10 of the uplink information transmission source in the member information DB 341. (Step T24), and transmits information (content information for displaying a privilege addition notification screen) to the vehicle-mounted device 10 via the communication unit 35 (step T25). ). Then, the process proceeds to step T27. In the benefit addition notification information transmitted in step T25, a code indicating immediate reproduction is stored as “immediate reproduction / accumulation code” of ID03.
When receiving the benefit addition notification information distributed from the center device 30, the control unit 4 of the vehicle-mounted device 10 displays a privilege addition notification screen on the display unit 1e based on the distributed information (step T26). FIG. 20C shows an example of a privilege addition notification screen displayed on the display unit 1e in step T26.

  If there are a plurality of information codes corresponding to the questionnaire in step T15, a plurality of different questionnaire screens may be transmitted for each information code, or one questionnaire screen common to all information codes corresponding to the questionnaire may be transmitted. One may be prepared and one common questionnaire screen may be transmitted. When a plurality of questionnaire screens are transmitted for each information code, the processes in steps T16 to T26 may be repeatedly executed for each questionnaire screen to be transmitted. Collectively, a single confirmation request command is transmitted to the vehicle-mounted device 10, and in response to the reception of the single confirmation request command, a response input button B2 is created for each questionnaire screen and displayed in the order in which the questionnaire screens are received. Then, confirmation response commands corresponding to the input responses may be sequentially transmitted to the center device 30. As described above, when the center device 30 transmits a confirmation request command to the vehicle-mounted device 10, the center device 30 can instruct the time from when the vehicle-mounted device 10 receives the command until a confirmation response is received. When transmitting one confirmation request command to the questionnaire screen, the center device 30 controls the number of questionnaire screens to be transmitted according to the response time instructed to the vehicle-mounted device 10. Or the response time instruct | indicated to the onboard equipment 10 is controlled according to the number of the questionnaire screens to transmit.

In step T <b> 27, the control unit 31 of the center device 30 organizes content information to be distributed based on the uplink information received from the vehicle-mounted device 10, and distributes the content information to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35. (Step T27).
In step T27, for example, content that distributes content information or the like classified into genre items preferred by the user among content information stored in the storage unit 34 with reference to preference genre data or the like of the received uplink information. And the corresponding content information is read from the storage unit 34 and distributed to the vehicle-mounted device 10.

  When the distribution of the content information is completed, the control unit 31 of the center device 30 generates message information for notifying the end of the distribution, and transmits the message information to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step T28).

  In the vehicle-mounted device 10, when the content information distributed from the center device 30 and the distribution end notification are received via the roadside wireless device 20, the control unit 4 of the vehicle-mounted device 10 has received whether or not all the content information is complete. The content information is checked for normality (step T29), the received content information is stored in the storage unit 1f, and the reception history is stored in the storage unit 1f (step T30). Specifically, the reception information code of the received content information is written in the reception / playback history information in the uplink information of the provider code stored in the storage unit 1f.

  And the control part 4 of the onboard equipment 10 reproduces | regenerates content information at a predetermined timing (step T31). Specifically, the content information stored in the storage unit 1f is read, and a screen is displayed on the display unit 1e based on the “display character data” and “display image data” of the read content information. The voice output unit 1g outputs a voice based on the “sound character string data”. Then, the control unit 4 stores the reproduction history by setting “1” to the reproduction identification flag corresponding to the information code of the content information in the uplink information stored in the storage unit 1f. The reproduction of the content information (T31) is possible even after the vehicle-mounted device 10 described later moves out of the mutual communication area Z.

  When the vehicle-mounted device 10 is moved out of the mutual communication area Z (area out) and communication with the roadside apparatus 20 is interrupted for a certain time or more, a series of information distribution processing ends.

  As described above, according to the second embodiment, the center device 30 includes the reproduction history of the content information subject to the questionnaire in the uplink information reception / reproduction history information received from the vehicle-mounted device 10. If it is determined that it is included, a confirmation request command that prompts the user to input an interface for inputting a YES / NO response to the questionnaire screen and the questionnaire is transmitted to the vehicle-mounted device 10. Upon receiving the confirmation request command, the control unit 4 of the vehicle-mounted device 10 displays the YES / NO response input button B2 on the questionnaire screen, and any of the YES / NO response input buttons B2 is pressed. Then, a confirmation response command corresponding to the input is transmitted to the center device 30. The center apparatus 30 totals the questionnaire responses based on the received confirmation response commands.

Accordingly, a distribution company that provides a content information distribution service conducts a questionnaire on the content information viewed by the user of the vehicle-mounted device 10 using the instruction response application, and obtains a questionnaire response. It is possible to collect information for improvement.
Moreover, the delivery provider can improve the service to a member by adding privilege points to the user who answered the questionnaire. The user of the vehicle-mounted device can acquire privilege points by answering the questionnaire.

[Third Embodiment]
Hereinafter, a third embodiment according to the present invention will be described.
First, the configuration of the third embodiment will be described.
Since the configuration of each device and the data configuration of content information and uplink information in the third embodiment are substantially the same as those in the first embodiment, the description is incorporated and different parts from the third embodiment. explain.

  In the third embodiment, as described in the first embodiment, the storage unit 34 of the center device 30 stores the program executed by the control unit 31, various data necessary for executing the program, and content information. In addition to storing the provider code individually assigned to the distribution provider, the content information to be distributed, and the member DB 341, a questionnaire count DB (not shown) for storing the questionnaire count results is stored. The storage unit 34 stores an information distribution history DB (not shown). The information distribution history DB is a database that stores the vehicle-mounted device ID of the vehicle-mounted device 10 that is the distribution target of content information in association with the information code of the distributed content information.

  The center device 30 and the vehicle-mounted device 10 are equipped with a communication function based on the vehicle-mounted device response application defined by ITS FORM RC-004 at the ITS information communication system promotion conference. It is possible to notify the confirmation request command from the device 30 to the vehicle-mounted device 10 or to transmit a confirmation response command to the confirmation request command in the vehicle-mounted device 10 to the center device 30.

  Next, the operation | movement between each apparatus of the information delivery system 100 in 3rd Embodiment is demonstrated.

FIGS. 21 to 22 are flowcharts for explaining the flow of processing in the center device 30, the roadside wireless device 20, the DSRC unit 3 of the vehicle-mounted device 10, and the control unit 4 when content information is distributed.
As shown in FIG. 21, when the engine of the vehicle C is started and the power of the vehicle-mounted device 10 is turned on (step A1), the control unit 4 generates the characteristic information of the vehicle-mounted device 10 and updates the storage unit 3c. Write to the link information storage area M (step A2). The characteristic information is obtained by the control unit 4 inquiring about each item such as the display unit 1e about items that have been negotiated with the center device 30 in advance, or by reading information stored in the storage unit 1f in advance. get. Then, the control unit 4 encodes the acquired information and writes the code in a corresponding area of the uplink information storage area M. Actually, control information for instructing writing is output to the DSRC control unit 3a, and the DSRC control unit 3a writes the information to the uplink information storage area M.

  Thereafter, when the vehicle C starts traveling and enters the mutual communication area Z of the roadside apparatus 20 (area-in), the roadside apparatus 20 detects the vehicle C and connects to the DSRC unit 3 of the vehicle-mounted device 10 through DSRC communication. Processing is started (steps A3a and A3b). That is, when a DSRC radio wave is transmitted and a response from the vehicle-mounted device 10 is obtained, a communication path is established. When the communication path is established, the roadside apparatus 20 transmits notification information indicating that the connection is completed to the center apparatus 30 (step A4a). On the other hand, the DSRC unit 3 of the vehicle-mounted device 10 outputs notification information indicating that the connection is completed to the control unit 4 (step A4b).

Next, the DSRC unit 3 transmits the characteristic information written in the uplink information storage area M to the roadside apparatus 20 (step A5). The characteristic information is transmitted to the center apparatus 30 via the roadside apparatus 20.
In the center apparatus 30, when the characteristic information is received by the communication unit 35, the control unit 31 determines whether the user of the vehicle-mounted device 10 is a member of the distribution service based on the vehicle-mounted device ID included in the received characteristic information. Authentication is performed and the authentication result is temporarily stored (step A6). Specifically, if there is an in-vehicle device ID that matches the received in-vehicle device ID among the on-vehicle device IDs of all members of the distribution service registered in the member information DB 341, it is determined as a member and matches the received in-vehicle device ID. If there is nothing, it is judged as a non-member.

  Next, the control unit 31 of the center device 30 distributes default content information to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step A7). Examples of default content information include Welcom screen information indicating the start of distribution of content information.

  Next, the control unit 31 of the center device 30 refers to the information distribution history DB stored in the storage unit 34 (step A8), and determines whether or not the received information distribution history of the vehicle-mounted device ID exists. When it is determined that the information distribution history of the received vehicle-mounted device ID exists (step A9; YES), the control unit 31 displays a questionnaire screen (more specifically, content information for displaying the questionnaire screen) from the storage unit 34. It reads and transmits to the onboard equipment 10 via the roadside apparatus 20 by the communication part 35 (step A10). In the content information for displaying the questionnaire screen transmitted in step A10, a code indicating immediate reproduction is stored as “immediate reproduction / accumulation code” of ID03, and the control unit 4 is received from the center device 30. The questionnaire screen is displayed on the display unit 1e.

  Examples of the questionnaire screen include a screen for inquiring whether or not the content information in general distributed by the distribution company has been useful in the past. Moreover, when the center apparatus 30 is connected only with the roadside apparatus 20 located at a predetermined point, the vehicle-mounted device 10 in which the information distribution history is stored has stopped at the same point in the past. It will be. For example, when the center apparatus 30 is connected only to the roadside apparatus 20 installed in a parking lot of a shopping center, the vehicle-mounted device 10 in which the information distribution history is stored in the center apparatus 30 I have visited the shopping center. Therefore, in such a case, a screen or the like for inquiring evaluation regarding facilities at a point where the roadside apparatus 20 is installed may be used as a questionnaire screen. Further, when the center device 30 is connected to a plurality of roadside wireless devices 20 existing at a plurality of points, an information distribution history DB is prepared for each roadside wireless device 20, and the vehicle-mounted device 10 and the center device 30 are currently prepared. By determining whether or not there is an information distribution history of the in-vehicle device 10 in the information distribution history DB for the roadside device 20 that is relaying to the roadside device 20, the in-vehicle device 10 has been associated with the roadside device 20 in the past. It is possible to determine whether or not the user has stopped at the installed point. Therefore, a questionnaire screen or the like about the facility at the point can be transmitted to the vehicle-mounted device 10 that has visited in the past.

Next, the control unit 31 of the center device 30 is a confirmation request command for requesting a YES / NO confirmation response in the vehicle-mounted device 10 stipulated by ITS FORM RC-004 in the ITS information communication system promotion conference. Is transmitted to the vehicle-mounted device 10 by the communication unit 35 (step A13). The confirmation request command includes information for prompting the output of the interface for the user to input a YES / NO response.
When the confirmation request command from the center apparatus 30 is received by the DSRC unit 3, the control unit 4 displays the input button B2 for response of YES / NO on the questionnaire of the display unit 1e based on the information included in the confirmation request command. It is displayed on the screen (step A14).

  In the vehicle-mounted device 10, when one of the input buttons B2 for response is pressed by the input unit 1d and a response of YES or NO to the question on the questionnaire screen is input (step A15), the control unit 4 responds to the input. The confirmation response command is generated and transmitted to the center apparatus 30 via the DSRC 3 and the roadside apparatus 20 (step A16).

  When the confirmation response command is received by the communication unit 35, the control unit 31 of the center apparatus 30 adds up the questionnaire responses based on the received confirmation response command (step A17). For example, if the confirmation response command includes a “YES” response, the control unit 31 adds 1 to the “YES” count in the questionnaire totalization result file stored in the storage unit 34, and confirms the response. When the command includes a “NO” response, the control unit 31 adds 1 to the “NO” count number of the questionnaire count result stored in the storage unit 34. Further, when the center device 30 transmits a confirmation request command to the vehicle-mounted device 10, the center device 30 can instruct a time from when the vehicle-mounted device 10 receives the command until a confirmation response is received. If the confirmation response command is not received, it is determined that the timeout has occurred and the questionnaire is not counted, or the answer is not counted.

  Next, the control unit 31 determines whether the user of the vehicle-mounted device 10 is a member or a nonmember based on the result of the member authentication performed in step A6, and determines that the user is a nonmember (FIG. 22 step A18). NO), the process proceeds to step A30.

  When it is determined that the user of the vehicle-mounted device 10 is a member (step A18; YES), the control unit 31 stores the “acquisition point” of the record corresponding to the vehicle-mounted device ID of the on-vehicle device 10 that is the source of the uplink information in the member information DB 341. "Addition of a predetermined number to the value of the field" adds bonus points (step A19), and notifies the addition of bonuses (added bonus points) (to display a bonus addition notification screen) Content information) is transmitted to the vehicle-mounted device 10 by the communication unit 35 (step A20). In the privilege addition notification information transmitted in step A20, a code indicating immediate reproduction is stored as “immediate reproduction / accumulation code” of ID03. And the control part 31 polls with respect to the onboard equipment 10 regularly (step A23, A26), and requests | requires transmission of the uplink information written in the uplink information storage area M. FIG.

  In the vehicle-mounted device 10, when receiving the bonus addition notification information distributed from the center apparatus 30, the control unit 4 displays a bonus addition notification screen on the display unit 1e based on the distributed information (step A21). .

  On the other hand, when it is determined in step A9 that there is no information distribution history of the received vehicle-mounted device ID (step A9; NO), the control unit 31 of the center device 30 is based on the result of the member authentication performed in step A6. It is determined whether the user of the vehicle-mounted device 10 is a member or a non-member. If it is determined that the user is a non-member (step A22; NO), the process proceeds to step A30.

  In the vehicle-mounted device 10, the control unit 4 collates the provider code included in the received default content information with the provider code included in the uplink information, thereby distributing in the center device 30 in which communication has been established. It is determined whether or not the business is a contracted business. If it is determined that it is not a contracted business operator (step A24; NO), the control unit 4 skips the processing of steps A25 to A29. That is, the uplink information is not written into the uplink information storage area M and the uplink information is not transmitted.

  If it is determined that the distribution company in the center device 30 is a contracted company (step A24; YES), the uplink information corresponding to the company code included in the received default content information is read from the storage unit 1f and uploaded. Write to the link information storage area M (step A25).

  When the control unit 4 writes the uplink information, the DSRC unit 3 transmits the uplink information stored in the uplink information storage area M to the roadside radio device 20 in response to polling from the center device 30. To the center device 30 (step A27).

In the center device 30, when uplink information is received via the communication unit 35, the control unit 31 transmits an uplink information release request to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step). A28). When receiving the uplink information release request transmitted from the center apparatus 30 via the roadside apparatus 20, the control unit 4 deletes the uplink information written in the uplink information storage area M in step A25, and stores the storage unit. The information written in the uplink information storage area M in step A25 is deleted from the past stop-in place information, reception / reproduction history information, and member information stored in 1f (step A29).
It should be noted that the uplink past visited location information, reception / playback history information, and member information stored in the storage unit 1f are saved without being deleted with a flag indicating that the uplink has been completed. May be managed. In this case, when the uplink information is written in the uplink information storage area M next time, the control unit 4 performs control so that information that has been uplinked and has the same content is not written.

In step A30, the control unit 31 of the center device 30 distributes based on the authentication result of whether the user of the vehicle-mounted device 10 is a member or a non-member, and the uplink information received from the vehicle-mounted device 10 when the user is a member. Content information to be organized is distributed to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step A30).
In step A30, if the user of the vehicle-mounted device 10 is a nonmember, the content information for nonmembers such as public advertisement information such as train delay information and tax payment notice information is read from the storage unit 34 and distributed. . Moreover, you may deliver the content information which displays the screen which notifies that it will receive points when it becomes a member. When the user of the vehicle-mounted device 10 is a member, for example, the preference genre data of the received uplink information is referred to, and the content information stored in the storage unit 34 is classified into the genre items that the user likes. The content information is selected as the content to be distributed, and the corresponding content information is read from the storage unit 34 and distributed to the vehicle-mounted device 10.

  When the distribution of the content information is completed, the control unit 31 of the center device 30 generates message information for notifying the end of the distribution, and transmits the message information to the vehicle-mounted device 10 via the roadside wireless device 20 by the communication unit 35 (step A31). In addition, the control unit 31 of the center device 30 records the vehicle-mounted device ID and the information code of the distributed content information in the information distribution history DB (step A32).

  In the vehicle-mounted device 10, when the content information distributed from the center device 30 and the distribution end notification are received via the roadside wireless device 20, the control unit 4 of the vehicle-mounted device 10 has received whether or not all the content information is complete.
