And the control part 4 sets a member registration cancellation | release flag to ON in the member registration cancellation | release flag area | region of the memory | storage part 1f (step S1003), and complete | finishes this process. The member registration cancellation flag ON is member registration cancellation information.

  The setting for canceling the distribution service member registration may be performed for all the registered distribution companies as described above, but may be performed for each distribution company. In the case where the member registration can be canceled for each distribution company, the control unit 4 is, for example, the distribution company (that is, the storage service) that has registered the membership of the distribution service on the display unit 1e at the start of the member registration cancellation setting process. A list of distribution operators whose business codes are registered in the uplink information of the section 1f is displayed so that the user can select a distribution business subject to member registration cancellation via the input section 1d. Then, in step S1001 of FIG. 11, the content information having the provider code of the distribution provider selected via the input unit 1d is deleted from the storage unit 1f, and in step S1002, the selected distribution provider's provider code is deleted. The uplink information is deleted from the storage unit 1f. In 1003, the member registration cancellation flag is set to ON in association with the provider code of the selected delivery provider.

  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 S5a and S5b in FIG. 9). 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 S6a). 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 S6b).

Next, the DSRC unit 3 transmits the characteristic information written in the uplink information storage area M to the roadside apparatus 20 (step S7). 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 S8).

  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 distribution services registered in the member information DB 341, and the user of the vehicle-mounted device 10 is a non-member. If it is determined that there is (step S8; NO), the non-member content information is read from the storage unit 34 and distributed to the vehicle-mounted device 10 via the roadside apparatus 20 by the communication unit 35 (step S9). When the distribution is completed, the control unit 31 of the center apparatus 30 generates message information for notifying the distribution end and transmits the message information to the vehicle-mounted device 10 (step S10), 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 it is determined that the user of the vehicle-mounted device 10 is a member (step S8; YES), the control unit 31 of the center device 30 The default content information for members is distributed to the vehicle-mounted device 10 by the communication unit 35 via the roadside apparatus 20 (step S11). 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 S12, S17), 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 company code, it is determined whether or not the distribution company that has distributed the received content information is a contracted company (step S13). If it is determined that the distribution company that has distributed the received content information is not a contracted company (step S13; NO), the control unit 4 proceeds to the process of step S30 and notifies the end of distribution from the center device 30. In response to the reception of the message information, it is checked whether or not all the content information is complete, whether or not the data of the received content information is all normal (step S30), and the received content information is stored in the storage unit 1f. Save (step S31). And the process in the control part 4 is complete | finished.

  On the other hand, if it is determined that the distribution company that distributed the received content information is a contracted company (step S13; YES), the control unit 4 sets the member registration cancellation flag in the member registration cancellation flag area of the storage unit 1f. It is determined whether or not it is set to ON. If it is determined that the member registration cancellation flag is not set to ON (step S14; NO), the process proceeds to step S16.

  If it is determined that the member registration cancellation flag is set to ON (step S14; YES), the control unit 4 “in the uplink information corresponding to the provider code of the distribution provider stored in the storage unit 1f”. In the “basic information”, a code indicating cancellation of member registration is written (step S15), and the process proceeds to step S16. Specifically, it is overwritten with a code indicating deregistration (for example, negotiating with each business operator and setting each digit of the business operator code to 0) in “business operator code” of “basic information”. Alternatively, 0 is written in “preference genre table version information” and 0 is written in 96 items of “preference genre data”. The information indicating the member registration cancellation is not limited to the above code indicating the member registration cancellation. For example, a flag or the like may be used to write a flag indicating the member registration cancellation in the uplink information. The member information of the link information may be written as cancellation of member registration. Further, the member registration cancellation may be indicated by writing 0 in only one of “preference genre table version information” and “preference genre data”.

  In step S16, the uplink information corresponding to the provider code of the distribution provider is read from the storage unit 1f and written in the uplink information storage area M (step S16).

  When the control unit 4 writes the uplink information to the uplink information storage area M, the DSRC unit 3 responds to the polling from the center device 30 and stores the uplink information stored in the uplink information storage area M. Information is transmitted to the center apparatus 30 via the roadside apparatus 20 (step S18).

  When the center device 30 receives the uplink information via the communication unit 35, the control unit 31 temporarily stores the received uplink information (step S19), and the communication unit 35 causes the roadside radio device 20 to be stored. The uplink information release request is transmitted to the vehicle-mounted device 10 via (step S20).

  When receiving the uplink information release request transmitted from the center device 30 via the roadside apparatus 20, the control unit 4 determines whether or not the member registration flag is set to ON in the member registration cancellation flag area of the storage unit 1 f. Is determined (step S21). When it is determined that the member registration cancellation flag is set to ON in the member registration cancellation flag area of the storage unit 1f (step S21; YES), the control unit 4 performs the business of the distribution provider stored in the storage unit 1f. The process of deleting the “basic information” of the uplink information having the user code is performed (step S22), the member registration cancellation flag is set to OFF (step S23), and the process of the control unit 4 is terminated. If it is determined that the member registration cancellation flag is not set to ON in the member registration cancellation flag area of the storage unit 1f (step S21; NO), the control unit 4 waits for reception of the content information and proceeds to the processing of step S30. To do.

  After transmitting the uplink information release request, the control unit 31 of the center device 30 determines whether or not the received uplink information matches a predetermined member registration cancellation condition (step S24). Specifically, the “business code” of “basic information” is a code indicating registration cancellation (for example, each digit of the business code is set to 0), or “preference genre table version” and “preference genre” If 96 items of “data” are 0, it is determined that the member registration cancellation condition is met.

  When it is determined that the received uplink information matches the member registration cancellation condition (step S24; YES), the control unit 31 matches the on-board device ID of the uplink information transmission source stored in the member information DB 341. The member registration information record corresponding to the device ID is deleted from the member information DB 341 (step S25), the content information for notifying the member registration release is read from the storage unit 34 (step S26), and the roadside apparatus 20 is communicated by the communication unit 35. Is distributed to the vehicle-mounted device 10 via (step S28).

When it is determined that the received uplink information does not match the member registration cancellation condition (step S24; NO), the control unit 31 organizes content information to be distributed based on the uplink information received from the vehicle-mounted device 10 ( In step S27), the communication unit 35 delivers the vehicle-mounted device 10 via the roadside apparatus 20 (step S28).
In step S27, the preference genre data of the received uplink information is referred to, and the content information classified into the genre item preferred by the user among the content information stored in the storage unit 34 is selected as the content to be distributed. Then, 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 notifying 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 S29).

  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 S30), the received content information is stored in the storage unit 1f, and the reception history is stored in the storage unit 1f (step S31). Specifically, in the reception history storage, the reception information code of the received content information is written in the reception / playback history information in the uplink information of the operator code stored in the storage unit 1f.

  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 first embodiment, on the initialization menu screen displayed on the display unit 1e of the vehicle-mounted device 10, "Distribution service member registration cancellation" or "All" is selected by the input unit 1d, and distribution is performed. When the service member registration cancellation is instructed, the control unit 4 executes a member registration cancellation setting process, deletes content information stored in the storage unit 1f and deletes information other than the basic information of the uplink information, and registers as a member. Set the release flag to ON. In addition, when the communication with the center device 30 is established, the control unit 4 determines whether or not the member registration cancellation flag is set to ON. If the member registration cancellation flag is set to ON, the control unit 4 A code indicating cancellation of member registration is written in the basic information of the link information and transmitted to the center device 30. When receiving the uplink information from the vehicle-mounted device 10, the center device 30 determines whether or not the basic information includes a code indicating cancellation of member registration. If the center device 30 determines that the code includes the code, the transmission source is transmitted from the member information DB 341. The member registration information of the record having the vehicle-mounted device ID of the vehicle-mounted device 10 is deleted, and the content information for notifying the member registration cancellation is transmitted to the vehicle-mounted device 10.

  Accordingly, the user inputs an instruction to cancel the membership registration of the distribution service to the vehicle-mounted device 10 by an operation on the initialization menu screen of the vehicle-mounted device 10, so that the content information and uplink information stored in the storage unit 1f, It becomes possible to delete personal information registered in the center device 30. Therefore, for example, when selling a vehicle equipped with the vehicle-mounted device 10 to a third party, it is possible to prevent personal information from remaining in the vehicle-mounted device or the center device.

Example 2 according to the present invention will be described below.
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, description will be cited and the operation of the second embodiment will be described below.

  FIG. 12 is a flowchart illustrating the flow of processing 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 in the second embodiment.

  As shown in FIG. 12, the second embodiment is different from the first embodiment only in the processes of step S <b> 3 and step S <b> 4 executed by the control unit 4.

  In FIG. 12, when the engine of the vehicle C is activated and the vehicle-mounted device 10 is turned on (step S1), the control unit 4 generates characteristic information of the vehicle-mounted device 10, and an uplink information storage area of the storage unit 3c. Write to M (step S2).

  In the vehicle-mounted device 10, when an instruction to change the home registration point of the car navigation unit 1 is input by the input unit 1 d according to the menu screen displayed on the display unit 1 e (step S <b> 3; YES), the home registration point change is performed by the control unit 4. Processing is executed (step S4).

  FIG. 13 is a flowchart showing the home registration point changing process executed by the control unit 4 in step S4 of FIG.

  When an instruction to change the home registration point is input by the input unit 1d, the control unit 4 displays an input screen (keyboard screen or the like) for inputting a home address or the like on the display unit 1e, and a new home registration point is displayed. Is received (step S201). When the home registration point is input from the input screen, the control unit 4 overwrites and changes the home registration point information stored in the storage unit 1f with the input point information (step S202). In step S201, a map screen or the like may be displayed, and the point designated by the input unit 1d may be input as a home registration point.

  Next, the control unit 4 displays an inquiry screen (not shown) asking the user whether or not to cancel the membership registration on the display unit 1e (step S203). In this inquiry screen, for example, a message such as “Do you want to cancel member registration of distribution service?”, A “YES” button for instructing member registration cancellation, a “NO” button for instructing not to cancel member registration, etc. Is displayed.

  When an instruction not to cancel the membership registration of the distribution service is input by pressing the “NO” button or the like by the input unit 1d (step S204; NO), the control unit 4 ends this process.

  When the member registration cancellation of the distribution service is instructed by pressing the “YES” button by the input unit 1d (step S204; YES), the control unit 4 executes a member registration cancellation setting process (step S205). This process ends. The member registration cancellation setting process executed in step S205 is the same as that described with reference to FIG.

  When the vehicle C starts traveling and enters the mutual communication area Z of the roadside radio device 20 (area in), the roadside radio device 20 detects the vehicle C and performs connection processing by the DSRC unit 3 of the on-vehicle device 10 by DSRC communication. Start (steps S5a and S5b in FIG. 12). Since the processing from area in to area out is the same as that described in the first embodiment, the description thereof is omitted.

  As described above, according to the second embodiment, according to the menu screen displayed on the display unit 1e of the vehicle-mounted device 10, the input unit 1d inputs a home registration point change instruction, and the input unit 1d performs a new home registration. When the point information is input, the control unit 4 changes the home registration point information stored in the storage unit 1f to the newly input home registration point information, and the member registration of the distribution service in the display unit 1e. Displays a screen for inquiring whether to cancel. When an instruction to cancel the membership registration of the distribution service is input, the control unit 4 executes a member registration cancellation setting process, and deletes contents information and basic information of the uplink information stored in the storage unit 1f. And set the member registration release flag to ON. In addition, when the communication with the center device 30 is established, the control unit 4 determines whether or not the member registration cancellation flag is set to ON. If the member registration cancellation flag is set to ON, the control unit 4 A code indicating cancellation of member registration is written in the basic information of the link information and transmitted to the center device 30. When receiving the uplink information from the vehicle-mounted device 10, the center device 30 determines whether or not the basic information includes a code indicating cancellation of member registration, and determines that the code indicating cancellation of member registration is included. The member registration information of the record having the vehicle-mounted device ID of the transmission source vehicle-mounted device 10 is deleted from the member information DB 341, and the content information for notifying the member registration cancellation is transmitted to the vehicle-mounted device 10.

  Therefore, when the user of the vehicle-mounted device 10 inputs the change of the home registration point from the input unit 1d, the user inputs the instruction for canceling the membership registration of the distribution service, and the content information stored in the storage unit 1f and the upload It becomes possible to delete link information, personal information registered in the center device 30, and the like. Therefore, for example, when a vehicle on which the vehicle-mounted device 10 is mounted is replaced, content information is distributed as set by the previous user, or personal information of the previous user remains in the vehicle-mounted device. It becomes possible to prevent.

Example 3 according to the present invention will be described below.
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, description will be cited and the operation of the third embodiment will be described below.

  FIG. 14 is a flowchart illustrating 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 in the third embodiment.

  As shown in FIG. 14, the third embodiment is different from the first embodiment only in the processes of step S <b> 3 and step S <b> 4 executed by the control unit 4.

  In FIG. 14, when the engine of the vehicle C is activated and the vehicle-mounted device 10 is turned on (step S1), the control unit 4 generates characteristic information of the vehicle-mounted device 10, and an uplink information storage area of the storage unit 3c. Write to M (step S2).

  Thereafter, the vehicle-mounted device 10 moves and detects that the engine switch key 6 is turned off via the I / F 5 (OFF signal), that is, detects the parking of the vehicle C (own vehicle) (step S3; YES), the control unit 4 executes home registration position detection processing (step S4).

  FIG. 15 is a flowchart showing the home registration position detection process executed by the control unit 4 in step S4 of FIG.

  When parking is detected, the control unit 4 reads out the home registration point information stored in the “home registration point” area of the storage unit 1f, and acquires the coordinates (latitude and longitude) of the home registration point (step S301). Next, the control unit 4 compares the coordinates of the current location (own vehicle position) of the vehicle C detected by the current location detection unit 1b with the coordinates of the acquired home registration point, and determines whether or not they are different ( Step S302). If it is determined that the coordinates of the home registration point and the coordinates of the vehicle position are not different (the same) (step S302; NO), the control unit 4 sets 0 as the number of verifications N (step S303), and the number of verifications N Is stored in a predetermined area of the storage unit 1f (step S304), and this process is terminated.

  As a result of the comparison, if it is determined that the coordinates of the home registration point and the coordinates of the current vehicle position are different (step S302; YES), the control unit 4 acquires the number of verifications N from the storage unit 1f (step S305). Next, the control unit 4 increments the verification count N by 1 (step S306), and determines whether the verification count N exceeds a predetermined reference count (step S307). If it is determined that the number of verifications N does not exceed a predetermined reference number (step S307; NO), the control unit 4 stores the number of verifications N in a predetermined area of the storage unit 1f (step S308), and performs this process. finish.

  On the other hand, if it is determined that the number of verifications N has exceeded a predetermined reference number (step S307; YES), the control unit 4 initializes the verification number N by setting 0 (step S309), and stores the number of verifications N. The data is stored in a predetermined area of the part 1f (step S310). And the control part 4 changes the home registration spot information memorize | stored in the "home registration spot information" area | region of the memory | storage part 1f into the information of the coordinate of the present own vehicle position (step S311), and member registration cancellation | release setting processing Is executed (step S312), and this process is terminated.

  The member registration cancellation setting process executed in step S312 is the same as that described with reference to FIG.

  When the vehicle C starts traveling and enters the mutual communication area Z of the roadside radio device 20 (area in), the roadside radio device 20 detects the vehicle C and performs connection processing by the DSRC unit 3 of the on-vehicle device 10 by DSRC communication. Start (steps S5a and S5b in FIG. 14). Since the processing of each device from area in to area out is the same as that described in the first embodiment, the description thereof is omitted.

  As described above, according to the third embodiment, the control unit 4 counts the number of times the parking is detected at a position different from the home registration point information registered in the storage unit 1f of the vehicle-mounted device 10 as the number of verifications N. The registration of home registration point information in the storage unit 1f is changed to the parking position when the number of verifications N exceeds a predetermined reference number, and member registration cancellation setting processing is executed and stored in the storage unit 1f. Content information and uplink information other than the basic information are deleted, and the member registration cancellation flag is set to ON. In addition, when the communication with the center device 30 is established, the control unit 4 determines whether or not the member registration cancellation flag is set to ON. If the member registration cancellation flag is set to ON, the control unit 4 A code indicating cancellation of member registration is written in the basic information of the link information and transmitted to the center device 30. When receiving the uplink information from the vehicle-mounted device 10, the center device 30 determines whether or not the basic information includes a code indicating cancellation of member registration, and determines that the code indicating cancellation of member registration is included. The member registration information of the record having the vehicle-mounted device ID of the transmission source vehicle-mounted device 10 is deleted from the member information DB 341, and the content information for notifying the member registration cancellation is transmitted to the vehicle-mounted device 10.

  Therefore, when the number of times of parking at a position different from the home registration point information exceeds a predetermined reference number, the home registration point information stored in the storage unit 1f is automatically changed to the own vehicle position, It is possible to delete content information, uplink information, personal information registered in the center device 30, and the like. Therefore, for example, when a vehicle on which the vehicle-mounted device 10 is mounted is replaced, content information is distributed as set by the previous user, or personal information of the previous user remains in the vehicle-mounted device. It becomes possible to prevent.

Embodiment 4 according to the present invention will be described below.
In the fourth embodiment, the storage unit 1f stores a parking position coordinate table (not shown). The parking position coordinate table corresponds to the coordinates of the parking position when parking is detected at a position different from the home registered spot information registered in the “home registered spot information” area of the storage unit 1f, and the number of parking at that coordinate. It is a table to be attached and stored.

  The configuration of each of the other devices and the data configuration of content information and uplink information in the fourth embodiment are substantially the same as those in the first embodiment, so that the description will be cited and the operation of the fourth embodiment will be described below.

  In the fourth embodiment, the flow of processing 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 distributing content information is the same as that shown in FIG. Incorporate. In this embodiment, since the home registration position detection process executed by the control unit 4 in step S4 is different, the process will be described with reference to FIG.

When parking of the vehicle C is detected, the control unit 4 acquires the coordinate information of the home registration point and the parking position coordinate table from the “home registration point” area of the storage unit 1f (step S401).
Next, the control unit 4 compares the coordinates of the current position (vehicle position) of the vehicle C detected by the current position detection unit 1b with the coordinates of the acquired home registration point, and determines whether or not they are different. (Step S402). If it is determined that the coordinates of the home registration point and the coordinates of the own vehicle position are not different (the same) (step S402; NO), the control unit 4 initializes the parking position coordinate table of the storage unit 1f (step S403), This process ends.

  As a result of the comparison, if it is determined that the coordinates of the home registration point and the coordinates of the current position are different (step S402; YES), the control unit 4 determines whether or not the coordinates of the current vehicle position exist in the acquired parking position coordinate table. Is determined (step S404). If it is determined that there is no current vehicle position coordinate in the acquired parking position coordinate table (step S404; NO), the control unit 4 sets the current vehicle position coordinate and the number of parking times to 1 in the parking position coordinate table. Registration is performed (step S405), and this process is terminated.

  If it is determined that the coordinates of the current vehicle position are present in the acquired parking position coordinate table (step S404; YES), the controller 4 determines the number of parking at the current vehicle position coordinates in advance by the current parking. It is determined whether or not the reference number has been exceeded (step S406). If it is determined that the number of parking at the current vehicle position coordinates does not exceed a predetermined reference number (step S406; NO), the control unit 4 corresponds to the coordinates of the current vehicle position in the parking position coordinate table. The number of parking to be performed is incremented by 1 (step S407), and this process is terminated.

  If it is determined that the number of parking at the current vehicle position coordinates exceeds a predetermined reference number due to the current parking (step S406; YES), the control unit 4 stores the “home registration point information” area in the storage unit 1f. The home registration point information is changed and registered with the coordinates of the current vehicle position (step S408), the member registration cancellation setting process is executed (step S409), and this process ends. Since the member registration cancellation setting process is the same as that described in the first embodiment, the description thereof is omitted.

  As described above, according to the fourth embodiment, the control unit 4 determines the coordinates of the parking position at a position different from the home registration point information registered in the storage unit 1f of the vehicle-mounted device 10 and the number of parking at the parking position. Is stored in the parking position coordinate table, and the registration of the home registration point information in the storage unit 1f is changed to the parking position when the number of parking at the current vehicle position exceeds a predetermined reference number. Then, the member registration cancellation setting process is executed, contents information and basic information of the uplink information stored in the storage unit 1f are deleted, and the member registration cancellation flag is set to ON. In addition, when the communication with the center device 30 is established, the control unit 4 determines whether or not the member registration cancellation flag is set to ON. If the member registration cancellation flag is set to ON, the control unit 4 A code indicating cancellation of member registration is written in the basic information of the link information and transmitted to the center device 30. When receiving the uplink information from the vehicle-mounted device 10, the center device 30 determines whether or not the basic information includes a code indicating cancellation of member registration, and determines that the code indicating cancellation of member registration is included. The member registration information of the record having the vehicle-mounted device ID of the transmission source vehicle-mounted device 10 is deleted from the member information DB 341, and the content information for notifying the member registration cancellation is transmitted to the vehicle-mounted device 10.

  Therefore, when the number of parkings at a position different from the home registration point information exceeds a predetermined reference number, the content information and uplink information stored in the storage unit 1f are automatically registered in the center device 30. It becomes possible to delete personal information. Therefore, for example, when a vehicle on which the vehicle-mounted device 10 is mounted is replaced, content information is distributed as set by the previous user, or personal information of the previous user remains in the vehicle-mounted device. It becomes possible to prevent.

As mentioned above, although Example 1-Example 4 was demonstrated, the said Example is a suitable example of this invention, and is not limited to this.
For example, the member registration in the center device 30 can be canceled by an application form such as the Internet or a postcard. For example, when accessing the Web page provided by the distributor from the vehicle-mounted device 10 or personal computer having the Internet connection function and inputting the vehicle-mounted device ID or the like and applying for the member registration cancellation, the center device 30 registers the member. The member registration information corresponding to the vehicle-mounted device ID described in the cancellation application is deleted from the member information DB. In this way, since the member / non-member authentication after the next area-in is always determined as a non-member, the distribution service is not provided.

  In addition, the membership information of the uplink information, the business operator code, or the membership registration information of the center device 30 has an expiration date, and the membership registration is canceled when there is no update due to the connection of the vehicle-mounted device ID for a certain period. Good.

  Moreover, in the said Example, the control part 4 detects the vehicle C (own vehicle) by detecting that the signal (OFF signal) to the effect that the engine switch key 6 was turned off was input via I / F5. However, the detection of parking is not limited to this.
