Then, when the ignition switch is turned on, the operating unit operates the acquiring unit, and the operating acquiring unit acquires the provision information prepared by the server device according to the preparation command from the server device via the network. Subsequently, the update unit updates the storage content of the storage unit with the provision information acquired by the acquisition unit.

  According to this information acquisition device, when the ignition switch is turned off, only a preparation command is transmitted to the server device. Therefore, it is possible to reduce power used for updating the provided information when the ignition switch is turned off. That is, according to the present invention, the ignition switch of the vehicle can be turned off without waiting for the update of the provided information to end. In addition, since the provided information is reliably updated even when the ignition switch is turned off, the user can use the new provided information the next time the vehicle is used. Furthermore, provided information can be reliably updated even when the power capacity of a power source that supplies power to the information acquisition device is small when the ignition switch is OFF.

  In addition, this information acquisition device is suitable when the server device is configured to provide provided information collected from other server devices. That is, the server device only has to collect the provision information from the other server device after receiving the preparation command until receiving the provision request, and when receiving the provision information provision request from the information acquisition device The provided information collected from other server devices can be immediately provided to the information acquisition device.

  Here, as described in claim 2, the present invention includes a time measuring unit for measuring time and a time zone range in which the time measured by the time measuring unit is preset when the ignition switch is turned off. If it is outside, it is desirable to include first operation prohibiting means for prohibiting the operation of the operating means.

  Here, the relay station may be a wireless base station that performs wireless communication with the information acquisition device, is wired to a wired network to which the server device is connected, and wirelessly connects the information acquisition device and the wired network. Alternatively, a wireless relay device that wirelessly relays between the information acquisition device and the wireless base station may be used.

  The communication start timing may be, for example, a timing at which the relay station receives a start signal indicating the start of communication from the information acquisition device, or a timing at which a preparation command from the information acquisition device to the server device is received. May be. Further, it may be the timing at which a request for data amount information or provision information made from the information acquisition device to the server device is received. The communication end timing may be, for example, a timing at which it is estimated that communication has ended after the relay station starts the server device, or an end signal indicating the end of communication from the information acquisition device. It may be the timing of receiving.

  Next, in the information system according to the invention described in claim 10, the first switch means in the relay station is the information acquisition device according to any one of claims 1 to 5 and any one of claims 6 to 8.

  According to the information system configured as described above, it is possible to prevent the relay station from consuming unnecessary power even though the information providing apparatus and the server apparatus are not communicating with each other.

  Here, at the communication start timing, for example, a start signal indicating the start of communication from the information acquisition device, a preparation command to the server device, a request for data amount information or provision information made to the server device is received. Alternatively, the first switch means may be configured, and the timing at which the first switch means receives them may be set.

  The communication end timing is, for example, the first switch means configured to measure the elapsed time since turning on the power source that drives the relay means, and the measured elapsed time is estimated to be the end of the communication. The timing at which the elapsed time is reached may be set. The first switch means may be configured to receive an end signal indicating the end of communication from the information acquisition device, and the timing at which the end signal is received from the information acquisition device may be set as the communication end timing.

  In the information system according to the eleventh aspect of the invention, in the relay station, the vehicle detection means is the information acquisition device according to any one of the first to fifth aspects and the server according to any one of the sixth to eighth aspects. When it is detected that the vehicle is located within the communicable range of the relay means for relaying communication with the apparatus, the second switch means turns on the power source for driving the relay means, and communication between the information acquisition apparatus and the server apparatus is performed. At the end timing, the power source for driving the relay means is turned off.

According to the information providing system configured as described above, it is possible to prevent wasteful power from being consumed at the relay station even though the vehicle is not located within the communicable range of the relay station.
Here, at the communication end timing, for example, the second switch unit is configured to measure the elapsed time since the power source for driving the relay unit is turned on, and the measured elapsed time is determined that the communication is completed. You may set the timing which reached the estimated elapsed time. Alternatively, the second switch means may be configured to receive an end signal indicating the end of communication from the information acquisition device, and the timing at which the end signal is received from the information acquisition device may be set as the communication end timing.

  The voltage of the RSSI signal supplied from the wireless device 111 is referred to as a preset voltage value (hereinafter referred to as “voltage threshold”, and in this embodiment, sufficient to establish stable wireless communication with the wireless base station 121. It is determined whether or not the voltage value is larger than (set a voltage value corresponding to the reception intensity of the ID signal) (S40). Here, when the voltage of the RSSI signal is larger than the voltage threshold, the travel history is acquired from the travel history storage unit 115 and the version of the map data stored as the provision information is acquired from the provision information storage unit 116. Then, an information profile (see FIG. 8A) storing these is generated (S50). When the generation of the information profile is completed, the information profile is transmitted as data to be transmitted to the communication control unit 112 (S60) and transmitted to the information management server 13.

  When the corresponding data or unupdated flag stored in the packet from the information management server 13 is received from the communication control unit 112 (Yes: S70), a lighting signal is output to the irradiation unit 119 (S80), and the repeater 15 Is notified of the end of communication, and the wireless signal amplifier 151 is turned off. When the output of the lighting signal is finished, it is confirmed whether or not the data received from the communication control unit 112 is the corresponding data (see FIG. 8B) (S90). The data is overwritten on the map data in the provided information storage unit 116, and the storage content of the provided information storage unit 116 is updated (S100). When the update of the stored contents is completed, a supply stop request is output to the standby power supply 117 (S120), and this process is terminated.

  In S10 and S20, if the vehicle is not located at a predetermined place or the current time is out of the predetermined time zone, the process immediately proceeds to S120, and then the process ends.

  In S40, when the voltage of the RSSI signal is equal to or lower than the voltage threshold, a lighting signal is output to the irradiation unit 119 (S110), and the repeater 15 is notified of the end of communication. And after shifting this process to S120, this process is complete | finished.

  If the corresponding data or the unupdated flag is not received in S70, the process waits until the corresponding data or the unupdated flag is received, and performs the processes of S80 to S100 together with the reception of the corresponding data or the unupdated flag. And after shifting this process to S120, this process is complete | finished.

If it is determined in S90 that the received flag is an unupdated flag, the process immediately proceeds to S120, and the process ends without updating the storage contents of the provided information storage unit 116.
Next, FIG. 3 is a block diagram showing an internal configuration of the information management server 13.

  As illustrated in FIG. 3, the information management server 13 captures a packet transmitted from the vehicle-mounted device 11 to the information management server 13 from the Internet 4, and obtains data (that is, an information profile from the vehicle-mounted device 11) from the captured packet. The data acquisition part 131 to extract and the provision information storage part 133 which memorize | stores the map data for providing to the onboard equipment 11 are provided. In addition, when the information management server 13 receives the information profile from the data acquisition unit 131, the information management server 13 performs an offer information acquisition process described below, and acquires an appropriate data from the provision information storage unit 133 or the service server 14, and an agent 134 The data transmission / reception unit 135 that mediates communication between the service server 14 and the service server 14, and data provision that stores data to be transmitted from the agent 134 to the vehicle-mounted device 11 (that is, corresponding data or an unupdated flag) and transmits the data to the vehicle-mounted device 11. Part 136.

  In addition, when the transmission / reception unit 135 receives an information acquisition request from the agent 134, the transmission / reception unit 135 stores the information acquisition request in a packet and sends the information acquisition request to the Internet 4. Further, the transmission / reception unit 135 takes in the packet addressed to the information management server 13 transmitted from the service server 14 from the Internet 4, extracts data (that is, the corresponding data or unupdated flag) from the packet, and sends it to the agent 134. Has been.

Here, FIG. 4 is a flowchart showing a flow of provided information acquisition processing performed by the agent 134.
As shown in FIG. 4, when the agent 134 receives the information profile from the data acquisition unit 131 and this process is started, first, map data corresponding to the travel history stored in the information profile is stored in the provided information storage. It is confirmed whether it is stored in the unit 133 (S200). Here, when the map data corresponding to the travel history is stored, it is confirmed whether or not the version of the map data matches the version of the map data stored in the information profile (S205). If so, an information acquisition request is created and sent to the transmission / reception unit 135 (S210), and is sent to the service server 14.

  When the corresponding data or the unupdated flag transmitted from the service server 14 is received from the transmission / reception unit 135 (Yes: S220), it is confirmed whether the received data is the corresponding data (S225). Here, if the data is the corresponding data, the corresponding data is supplied to the provision information storage unit 133 to update the storage content of the provision information storage unit 133 (S230), and the corresponding data is also supplied to the data provision unit 136. (S250) to transmit to the vehicle-mounted device 11, and this process is terminated.

  In S200, if the map data corresponding to the travel history stored in the information profile is not stored in the provided information storage unit 133, the process immediately proceeds to S210, and from S220 to S230 and S250. After the processing, this processing is terminated.

  In S205, if the version of the map data stored in the information profile does not match the version of the map data stored in the provided information storage unit 133 (that is, if the corresponding data is in the provided information storage unit 133). ), After obtaining the corresponding data from the provision information storage unit 133 (S240), the process is terminated through the process of S250.

  If it is determined in S225 that the received flag is an unupdated flag, the process immediately proceeds to S250, the unupdated flag is supplied to the data providing unit 136, and the unupdated flag is transmitted to the vehicle-mounted device 11. Then, this process ends.

  In the information system 1 configured as described above, as shown in the sequence diagram of FIG. 7, when the vehicle ignition SW 20 is turned off, the vehicle-mounted device 11 first irradiates the repeater 15 with infrared rays (1), Notify the start of communication. As a result, the repeater 15 turns on the wireless signal amplifier 151 of the repeater 15 (2). Subsequently, the vehicle-mounted device 11 generates an information profile and transmits it to the information management server 13 (3). Then, the information management server 13 analyzes the contents of the information profile (4), and obtains corresponding data (unupdated flag if there is no such data) from the provided information storage unit 133 or the service server 14 of the information management server 13. Provide to the vehicle-mounted device 11 (5).

  When the corresponding data or the unupdated flag is received, the vehicle-mounted device 11 irradiates the repeater 15 with infrared rays (6), and notifies the repeater 15 of the end of communication. As a result, the repeater 15 turns off the wireless signal amplifier 151 of the repeater 15 (7). Subsequently, when receiving the corresponding data in (6), the vehicle-mounted device 11 updates the storage content of the provided information storage unit 116 in the vehicle-mounted device 11 with the corresponding data (8), and then reserves the vehicle-mounted device 11 The power supply 117 is turned off (9), and the operation is stopped. Note that when the in-vehicle device 11 receives the unupdated flag in (6), the on-vehicle device 11 immediately turns off the standby power source 117 of the on-vehicle device 11 (9) and stops its operation.

  From the above, according to the information system 1 of the present embodiment, the ignition switch of the vehicle can be turned off without waiting for the update of the map data. In addition, since the map data is surely updated even when the ignition switch is turned off, the user can use new map data the next time the vehicle is used.

  Further, since the on-vehicle device 11 starts to acquire the map data only when the time when the ignition switch is turned off is within a predetermined time zone, the on-vehicle device 11 acquires the map data every time the ignition switch is turned off. There is no end to it. That is, it is possible to prevent the charging power of the secondary battery of the standby power source 117 from being consumed unnecessarily.

  In addition, since the map data acquisition is started only when the vehicle is at a predetermined location (that is, a parking lot equipped with the repeater 15) when the ignition switch is turned off, the provided information storage unit 116 has a location other than this. It is possible to prevent the update of the stored contents.

  Furthermore, since the map data is acquired only when the radio wave from the radio base station 121 has sufficient reception strength (that is, when stable radio communication is possible), the map data is surely stored. Can be acquired.

  In addition, the vehicle-mounted device 11 immediately turns off the standby power supply 117 when it is not necessary to update the storage contents of the provided information storage unit 116 (that is, when an unupdated flag is received from the information management server 13). Therefore, it is possible to prevent wasteful consumption of the power of the standby power supply 117.

  Further, since the information management server 13 and the service server 14 provide map data according to the travel history of the vehicle, even on-vehicle equipment such as map data at positions greatly deviating from the travel route. 11 can be prevented.

  The repeater 15 turns on the radio signal amplification unit 151 only when the vehicle-mounted device 11 and the wireless base station 121 (information management server 13) are performing wireless communication, and thus the vehicle-mounted device 11 and the wireless base station 12 Although the wireless communication is not performed, it is possible to prevent wasteful power consumption. Thereby, the cost (running cost) required to use the repeater 15 can be reduced.

  In this embodiment, the time measurement unit 114 is the time measurement unit according to claim 2, the coordinate data acquisition unit 113 is the position acquisition unit according to claim 3, and the wireless device 111 is the intensity detection unit according to claim 4. It corresponds to. Then, S10, 20, and 40 performed by the information processing unit 118 are respectively the first operation prohibiting means according to claim 2, the second operation prohibiting means according to claim 3, and the third operation prohibiting according to claim 4. Corresponds to means.

In the present embodiment, the information management server 13 corresponds to the server device according to claims 7 and 8, and the communication detection sensor 153 and the switch unit 154 of the repeater 15 serve as the first switch means according to claim 10. Equivalent to.
[Second Embodiment]
Next, a second embodiment will be described.

  In addition, the information system of this embodiment changes a part of setting of the onboard equipment 11 and the information management server 13 in the information system 1 of 1st Embodiment. Therefore, here, description is omitted about the part which is common in the information system 1 of 1st Embodiment, and only a different part is explained in full detail.

  First, in the vehicle-mounted device 11 of the present embodiment, the information processing unit 118 is configured to perform the following request processing and acquisition processing, and acquire corresponding data or an unupdated flag from the information management server 13.

Here, FIG. 9 is a flowchart showing a flow of request processing performed by the information processing unit 118 of the present embodiment.
As shown in FIG. 9, when the ignition switch 20 of the vehicle is turned off and this processing is started, the information processing unit 118 first takes in coordinate data from the coordinate data acquisition unit 113, and the vehicle is moved to a predetermined location (first implementation). (S300). Here, if it is determined that the vehicle is located at a predetermined location, the time measured by the time measurement unit 114 is referred to and the current time is a predetermined time zone (set in the same manner as in the first embodiment). It is determined whether it is within the range (S310). As a result, if it is determined that the current time is within the range of the predetermined time zone, a lighting signal is output to the irradiation unit 119 (S320), the start of communication is notified to the repeater 15, and the wireless signal amplification unit 151 of the repeater 15 is transmitted. Turn on.

  Then, it is determined whether or not the voltage of the RSSI signal supplied from the wireless device 111 is larger than a voltage threshold (set in the same manner as in the first embodiment) (S330). Here, when the voltage of the RSSI signal is larger than the voltage threshold, an information profile similar to the information profile generated by the information processing unit 118 of the first embodiment is generated (S340). When the generation of the information profile is completed, the information profile is sent to the communication control unit 112 as data to be transmitted (S350), and is transmitted to the information management server 13.

  Subsequently, after the corresponding data acquisition command for the information processing unit 118 is stored in the provision information storage unit 116 (S360), a lighting signal is output to the irradiation unit 119 (S370), and the repeater 15 is notified of the end of communication. Notice. When the output of the lighting signal is finished, a supply stop request is output to the standby power source 117 (S380), and this process is finished.

  In S300, S310, and S330, if the vehicle is not located at a predetermined location, the current time is out of the range of the predetermined time zone, or the voltage of the RSSI signal is equal to or lower than the voltage threshold, this processing is performed. Immediately after shifting to S370 and S380, this process is terminated.

Next, FIG. 10 is a flowchart showing the flow of acquisition processing performed by the information processing unit 118 of this embodiment.
As shown in FIG. 10, when the ignition switch 20 of the vehicle is turned on and this process is started, the information processing unit 118 first checks whether or not an acquisition command is stored in the provided information storage unit 116 ( S400). Here, when the acquisition command is stored, the coordinate data is acquired from the coordinate data acquisition unit 113 to determine whether or not the vehicle is located at the predetermined location (S410), and the vehicle is located at the predetermined location. If it is, a lighting signal is output to the irradiation unit 119 (S420), and the start of communication is notified to the repeater 15.

  Subsequently, it is determined whether or not the voltage of the RSSI signal is larger than the voltage threshold (S430). If the voltage is larger than the voltage threshold, the acquisition command is deleted from the provision information storage unit 116 (S440), and then the information management server 13 Transmits a transmission request for transmitting the corresponding data and the unupdated flag to the communication control unit 112 (S450).

  When the corresponding data or the unupdated flag is received from the information management server 13 (Yes: S460), a lighting signal is output to the irradiation unit 119 (S470), and the repeater 15 is notified of the end of communication. When the output of the lighting signal is finished, it is confirmed whether or not it is the corresponding data received from the communication control unit 112 (S475). If it is the corresponding data, the received corresponding data is stored in the provided information storage unit 116. After overwriting the map data and updating the stored contents of the provided information storage unit 116 (S480), the process is terminated.

  In S400, S410, and S475, if the acquisition command is not stored in the provision information storage unit 116, the vehicle is not located at a predetermined location, or the received flag is an unupdated flag, this processing is performed. Exit immediately.

  In S430, if the voltage of the RSSI signal is equal to or lower than the voltage threshold value, a lighting signal is output to the irradiation unit 119 (S490), the end of communication is notified to the repeater 15, and then this process is terminated. .

  In S460, if the corresponding data or the unupdated flag has not been received, the process waits until the corresponding data or the unupdated flag is received, and the process proceeds to S470 to S480 along with the reception of the corresponding data or the unupdated flag. After that, this process ends.

  Next, in the information management server 13 of the present embodiment, the agent 134 is set to perform the provision information acquisition process shown below to provide the corresponding data and the unupdated flag to the vehicle-mounted device 11.

  Here, FIG. 11 is a flowchart showing a flow of provided information acquisition processing performed by the agent 134 of the present embodiment. However, since the provision information acquisition process of this embodiment is only a partial change of the provision information acquisition process of the first embodiment, the same processes as the provision information acquisition process of the first embodiment are denoted by the same reference numerals. A description thereof will be omitted.

  As illustrated in FIG. 11, when the agent 134 receives an information profile from the data acquisition unit 131 and this process is started, first, similarly to the provided information acquisition process of the first embodiment, the processes of S200 to S230 are performed. I do. When a transmission instruction is received from the data acquisition unit 131 (Yes: S245), the corresponding data is retrieved from the provision information storage unit 133 (S246), and then through the processing of S250 (that is, the corresponding data is provided by the provision information storage unit 133). If it is stored, the corresponding data is supplied to the data providing unit 136. If not stored, the unupdated flag is supplied to the data providing unit 136), and this process is terminated.

If the versions do not match in S205, the process immediately proceeds to S245, and then the process ends through S246 and S250.
In S245, if a transmission instruction is not received from the data acquisition unit 131, the process waits until a transmission instruction is received, and after the transmission instruction is received, the process proceeds to S246 and S250, and then the process ends. To do.

  In the information system of this embodiment configured as described above, as shown in the sequence diagram of FIG. 12, when the vehicle ignition switch 20 is turned off, the vehicle-mounted device 11 irradiates the repeater 15 with infrared rays (1). , Notify the start of communication. The repeater 15 detects this and turns on the wireless signal amplifier 151 of the repeater 15 (2). And after the onboard equipment 11 produces | generates an information profile and transmits to the information management server 13 (3), infrared rays are again irradiated to the repeater 15 (4), and the completion | finish of communication is notified. The repeater 15 detects this and turns off the wireless signal amplifier 151 (5). Subsequently, the vehicle-mounted device 11 turns off the standby power supply 117 of the vehicle-mounted device 11 (6) and stops its operation. When the information management server 13 receives the information profile, the information management server 13 analyzes the content of the received information profile (7) and prepares the corresponding data (8).

  When the ignition SW 20 is turned on, the vehicle-mounted device 11 irradiates the repeater 15 with infrared rays (9) to notify the start of communication. Thereby, the repeater 15 detects the irradiated infrared rays and turns on the wireless signal amplifier 151 (10). When the infrared irradiation ends, the vehicle-mounted device 11 transmits a transmission request to the information management server 13 (11). When receiving the transmission request, the information management server 13 provides the corresponding data or the unupdated flag to the vehicle-mounted device 11 (12).

  When the corresponding data or the unupdated flag is received, the vehicle-mounted device 11 irradiates the repeater 15 with infrared rays (13), and notifies the repeater 15 of the end of communication. As a result, the repeater 15 detects the irradiated infrared ray and turns off the wireless signal amplifier 151 (14). And the onboard equipment 11 will update the memory content of the provision information storage part 116 in the said onboard equipment 11 with applicable data, when applicable data are received in (13) (15). In addition, the onboard equipment 11 does not update the storage content of the provision information storage part 116, when an unupdate flag is received in (13), and complete | finishes an acquisition process.

  From the above, according to the information system of the present embodiment, when the ignition switch 20 is turned off, the information profile is only transmitted to the information management server 13, so that the provided information is updated when the ignition switch 20 is turned off. Therefore, the power used can be reduced. That is, not only can the same effect as the information system 1 of the first embodiment be obtained, but also the power capacity of the secondary battery provided in the standby power supply 117 that supplies power to the vehicle-mounted device 11 when the ignition switch 20 is OFF is small. Even provided information can be updated.

  In the information system of this embodiment, the information management server 13 collects (acquires) the corresponding data from the provided information storage unit 133 or the service server 14 after receiving the information profile and before receiving the transmission request for the corresponding data. What is necessary is just to be able to provide, and when the transmission request | requirement is received from the onboard equipment 11, the applicable data collected can be provided to the onboard equipment 11 immediately.

  In the information system according to the present embodiment, the repeater 15 consumes wasted power in the wireless signal amplification unit 151 even though communication between the vehicle-mounted device 11 and the information management server 13 is not performed. Can be prevented.

In the present embodiment, the provision information storage unit 116 of the vehicle-mounted device 11 is the storage unit described in claim 1, and S350 performed by the wireless device 111, the communication control unit 112, and the information processing unit 118 is the command unit of claim 1. It corresponds to. Further, S450 and 460 performed by the wireless device 111, the communication control unit 112, and the information processing unit 118 correspond to the acquisition unit and the operation unit according to claim 1, and S480 performed by the information processing unit 118 corresponds to the update unit according to claim 1. To do.

  Note that the information system of the present embodiment is obtained by partially changing the settings of the information management server 13 in the information system 1 of the first embodiment. Therefore, here, description is omitted about the part which is common in the information system 1 of 1st Embodiment, and only a different part is explained in full detail.

  First, in the information management server 13 of this embodiment, the agent 134 accesses the service server 14 every preset time, acquires the latest map data from the service server 14, and stores the acquired map data in the provided information storage The information stored in the provision information storage unit 133 is set to be supplied to the unit 133 and updated. Then, the provision information acquisition process shown below is performed, and the corresponding data or the unupdated flag is set to be sent to the data providing unit 136.

  Here, FIG. 13 is a flowchart showing the flow of provided information acquisition processing performed by the agent 134. However, since the provision information acquisition process of this embodiment is only a partial change of the provision information acquisition process of the first embodiment, the same processes as the provision information acquisition process of the first embodiment are denoted by the same reference numerals. A description thereof will be omitted.

  As illustrated in FIG. 13, when the agent 134 receives an information profile from the data acquisition unit 131 and this process is started, first, similarly to the provided information acquisition process of the first embodiment, the processes of S200 and S205 are performed. I do. In S205, if the map data stored in the provided information storage unit 133 does not match the version of the map data stored in the information profile, the map data stored in the provided information storage unit 133 Is supplied to the data providing unit 136 as corresponding data (S251), and this process is terminated.

  In S200 and S205, if the map data corresponding to the travel history stored in the information profile is not stored in the provided information storage unit 133 or the versions match, an unupdated flag is set in the data providing unit 136. (S252), and the process is terminated.

  According to the information system of the present embodiment configured as described above, when the agent 234 constantly updates the stored content of the provided information storage unit 133, the latest relevant data is received when the information profile is received from the vehicle-mounted device 11. Can be immediately provided to the vehicle-mounted device 11. Note that the information system of this embodiment operates in the same manner as the information system 1 of the first embodiment (see FIG. 7).

Here, in this embodiment, the information management server 13 corresponds to the server device according to claims 6 and 7.
[Reference form]
Next, a reference form will be described.

  In addition, the information system of this reference form changes a part of setting of the onboard equipment 11 and the information management server 13 in the information system 1 of 1st Embodiment. Therefore, here, description is omitted about the part which is common in the information system 1 of 1st Embodiment, and only a different part is explained in full detail.

  First, in the information management server 13 of the present embodiment, the agent 134 is set to perform the provision information acquisition process described below and to provide the corresponding data or the unupdated flag to the vehicle-mounted device 11.

  Here, FIG. 14 is a flowchart showing the flow of provided information acquisition processing performed by the agent 134 of the present embodiment. However, since the provision information acquisition process of the present embodiment is only a part of the flow of the provision information acquisition process in the first embodiment, the same process as the provision information acquisition process of the first embodiment is the same. Reference numerals are assigned and explanations thereof are omitted.

  As illustrated in FIG. 14, when the agent 134 receives an information profile from the data acquisition unit 131 and this process is started, first, similarly to the provided information acquisition process of the first embodiment, the processes of S200 to S230 are performed. I do. Subsequently, the data amount of the acquired corresponding data is calculated (S247), the capacity data indicating the data amount is sent to the data providing unit 136 (S248), and transmitted to the vehicle-mounted device 11. Then, when a transmission instruction is received from the data acquisition unit 131 (Yes: S249), the corresponding data is supplied to the data providing unit 136 (S253) and transmitted to the vehicle-mounted device 11, and then this process is terminated.

If it is determined in S225 that the received flag is an unupdated flag, the received unupdated flag is sent to the data providing unit 136 (S254), and the process is terminated.
If no transmission instruction is received from the data acquisition unit 131 in S249, the process waits until a transmission instruction is received. After the transmission instruction is received, the process proceeds to S253, and then the process ends.

  Next, in the vehicle-mounted device 11 according to the present embodiment, the information processing unit 118 detects the voltage of the secondary battery provided in the standby power source 117 from a path not shown in FIG. 1 and charges the detected voltage to the secondary voltage. The calculated power (hereinafter referred to as “charging power”) is calculated. Then, based on the calculated charging power, the power consumption of the vehicle-mounted device 11, the data transfer rate, and the like, the information is acquired from the information management server 13 using only the charging power of the secondary battery, and the stored content of the provided information storage unit 116 is updated. It is set so as to calculate the amount of map data (hereinafter referred to as “data threshold value”).

Further, the information processing unit 118 is set to perform the following request processing and acquisition processing and acquire the corresponding data from the information management server 13.
Here, FIG. 15 is a flowchart showing a flow of request processing performed by the information processing unit 118 of the present embodiment.

  As shown in FIG. 15, when the ignition switch 20 of the vehicle is turned off and this processing is started, the information processing unit 118 first takes in coordinate data from the coordinate data acquisition unit 113, and the vehicle is moved to a predetermined location (first implementation). (S700). Here, if it is determined that the vehicle is located at a predetermined location, the time measured by the time measurement unit 114 is referred to and the current time is a predetermined time zone (set in the same manner as in the first embodiment). It is determined whether it is within the range (S710). As a result, when the current time is within the range of the predetermined time zone, a lighting signal is output to the irradiation unit 119 (S720), and the start of communication is notified to the repeater 15.

  Subsequently, it is determined whether or not the voltage of the RSSI signal supplied from the wireless device 111 is larger than a voltage threshold (set in the same manner as in the first embodiment) (S730). An information profile similar to the information profile generated by the information processing unit 118 of the first embodiment is generated (S740). When the generation of the information profile is completed, the information profile is sent to the communication control unit 112 as data to be transmitted (S750), and is transmitted to the information management server 13.

  When capacity data or an unupdated flag is received from the communication control unit 112 (Yes: S755), it is confirmed whether or not the received capacity data is capacity data (S756). After calculating the charging power of the secondary battery provided in 117 (S760), the data threshold value is calculated (S765). Here, it is determined whether the data amount indicated by the capacity data is larger than the data threshold value (S770). If the data amount is larger than the data threshold value, the provision information storage unit 116 issues an instruction to acquire the corresponding data to the information processing unit 118. (S775). When the acquisition information is stored in the provision information storage unit 116, a lighting signal is output to the irradiation unit 119 (S785), the end of communication is notified to the repeater 15, and a supply stop request is output to the standby power source 117. (S790), this process ends.

If it is determined in S756 that the received flag is an unupdated flag, the process immediately proceeds to S785, and then the process is terminated through S790.
If the amount of data indicated by the capacity data is equal to or smaller than the data threshold value in S770, the information processing unit 118 performs an update process (S780) described later, and then ends this process through S785 and S790.

  In S700, S710, and S730, if the vehicle is not located at a predetermined location, the current time is out of the predetermined time zone, or the voltage of the RSSI signal is equal to or lower than the voltage threshold, this processing is performed. Immediately after proceeding to S785 and S790, this process is terminated.

  In S755, if capacity data or an unupdated flag has not been received, the process waits until capacity data or an unupdated flag is received, and the process proceeds to S756 to S790 upon receipt of the capacity data or the unupdated flag. After that, this process ends.

Here, FIG. 16 is a flowchart showing the flow of the update process in S780 of the request process.
As shown in FIG. 16, when this processing is started, the information processing unit 118 first sends a transmission request for causing the information management server 13 to transmit the corresponding data to the communication control unit 112 (S800). The transmission request is transmitted to the information management server 13 as data to be transmitted. When the corresponding data is received from the information management server 13 (Yes: S810), the received data is overwritten on the map data in the provided information storage unit 116, and the storage content of the provided information storage unit 116 is updated ( S820), the process is terminated.

  If the corresponding data is not received in S810, the process waits until the corresponding data is received, and the process ends with the reception of the corresponding data, and then the process ends.

Next, FIG. 17 is a flowchart illustrating a flow of acquisition processing performed by the information processing unit 118 of the present embodiment.
As shown in FIG. 17, when the ignition switch 20 of the vehicle is turned on and this processing is started, the information processing unit 118 first checks whether or not an acquisition command is stored in the provided information storage unit 116 ( S900). Here, when the acquisition command is stored, the coordinate data is acquired from the coordinate data acquisition unit 113, and it is determined whether or not the vehicle is located at a predetermined location (S910). As a result, when the vehicle is located at a predetermined location, a lighting signal is output to the irradiation unit 119 (S920), and the repeater 15 is notified of the start of communication.

  Subsequently, it is determined whether or not the voltage of the RSSI signal is larger than the voltage threshold (S930). If the voltage is larger than the voltage threshold, the acquisition command is deleted from the provision information storage unit 116 (S940), and then the information management server 13 Transmits a transmission request for transmitting the corresponding data to the communication control unit 112 (S950).

  When the corresponding data is received from the information management server 13 (Yes: S960), a lighting signal is output to the irradiation unit 119 (S970), and the end of communication is notified to the repeater 15. When the output of the lighting signal is completed, the received data is overwritten on the map data in the provided information storage unit 116, the storage content of the provided information storage unit 116 is updated (S980), and this process is ended.

  In S900, S910, and S930, if the acquisition command is not stored in the provided information storage unit 116, the vehicle is not located at a predetermined location, or the voltage of the RSSI signal is equal to or lower than the voltage threshold, This process ends immediately.

  If the corresponding data has not been received in S960, the process waits until the corresponding data is received, and after the process proceeds to S970 and S980 together with the reception of the corresponding data, the process ends.

  In the information system of the present embodiment configured as described above, if the data amount of the corresponding data is equal to or less than the data threshold value, the corresponding data is acquired when the ignition SW 20 is OFF, and stored in the provided information storage unit 116 of the vehicle-mounted device 11. Update the content. On the other hand, if the data amount of the corresponding data is larger than the data threshold value, the corresponding data when the ignition SW 20 is ON is acquired, and the stored content of the provision information storage unit 116 is updated.

  As described above, according to the information system of the present embodiment, it is possible to prevent the acquisition of the corresponding data even though the charging power of the standby power supply of the vehicle-mounted device 11 is not sufficient to acquire the corresponding data. .

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various forms can be taken as long as they belong to the technical scope of the present invention. .

  For example, in any of the above-described embodiments, the information management server 13 or the service server 14 determines whether the version of the map data that each has matches the version of the map data stored in the vehicle-mounted device 11. However, it may be set so that the vehicle-mounted device 11 performs this determination. In this case, first, the information management server 13 and the service server 14 are set so that the latest version of the map data stored therein is provided to the vehicle-mounted device 11. And about the onboard equipment 11, it determines whether the version of the map data provided from the information management server 13 and the version of the map data which the said onboard equipment 11 corresponds, and it does not correspond It is only necessary to set to update the stored map data.

  In any of the above embodiments, the information management server is arranged on the Internet 4.

An information management server may be arranged in the local segment 5 having a station. In this case, since the provision information can be transmitted from the information management server to the vehicle-mounted device 11 without going through the Internet 4, the time taken for the provision information to reach the vehicle-mounted device 11 can be shortened compared to any of the above embodiments. If the router connecting the local segment 5 and the Internet 4 is set so as to prevent unauthorized access from the Internet 4 to the local segment 5, the confidentiality of the information provided to the vehicle-mounted device 11 is set. Can be further improved compared to the above embodiment.

  Moreover, in any of the information systems of the above embodiments, the information management server is always turned on, but may be set to be turned on only when communicating with the vehicle-mounted device 11. In this case, for example, when a notification to start communication is received from the vehicle-mounted device 11, a start signal for starting the information management server is transmitted to the information management server, and a notification to end the communication is sent. When received, the repeater 15 or the radio base station 121 is configured to transmit a stop signal for stopping the information management server. The information management server may be provided with a power supply device that turns on power to the information management server at the timing of receiving the activation signal and stops turning on the power at the timing of receiving the stop signal. According to such a providing system, power is not consumed in the information management server even though communication with the vehicle-mounted device 11 is not performed, so that the running cost of the providing system can be reduced.

  In any of the above embodiments, the vehicle-mounted device 11 notifies the repeater 15 of the start and end of communication using infrared rays. However, the vehicle-mounted device 11 may perform notification using weak radio waves. In this case, the repeater 15 may be provided with a receiver that receives weak radio waves instead of the communication detection sensor 153. Further, the repeater 15 is set to start measuring the elapsed time when receiving a communication start notification from the vehicle-mounted device 11 and to turn off the wireless signal amplifying unit 151 when the time to end communication has elapsed. May be.

  Further, the repeater 15 may be configured to detect that the vehicle has entered the parking lot and to turn on the wireless signal amplifier 151. In this case, for example, an infrared sensor for detecting the vehicle may be newly provided in the repeater 15.

  In any of the above-described embodiments, the vehicle-mounted device 11 and the information management server use the map data as the provided information, but are set to process other data such as traffic information data, weather forecast data, and music data as the provided information. Of course, it is possible.

  Moreover, in the said embodiment, although the onboard equipment 11 and the wireless base station 121 were performing wireless communication via the repeater 15, you may be set so that wireless communication can be performed without relaying the repeater 15. . In this case, similarly to the repeater 15, the radio base station 121 is set to turn on or off the radio base station 121 every time it receives notification of the start and end of communication from the vehicle-mounted device 11. It is preferable. Of course, it may be configured to detect that the vehicle is located in the parking lot and to turn on the power of the wireless base station 121.
