  (Step S406) The terminal processing unit 123 stores the destination information received in step S405 in the terminal storage unit 121. The process returns to step S401.

  (Step S407) The activation command receiving unit 1251 determines whether a startup command is received from the in-vehicle device 13. When the activation command is received, the process goes to step S408, and when the activation command is not received, the process returns to step S401.

  (Step S408) The activation processing unit 1232 reads an application corresponding to the activation command from the terminal storage unit 121 and activates it.

  (Step S409) The receiving unit 1221 determines whether or not a destination information transmission instruction has been received. When the transmission instruction of the destination information is accepted, the process goes to step S410. When the transmission instruction of the destination information is not accepted, the process goes to step S413.

  (Step S410) The destination information transmission unit 1242 transmits the destination information to the on-vehicle apparatus 13. The destination information is the destination information stored in the terminal storage unit 121 or the destination information received in step S409 and included in the destination information transmission instruction.

  (Step S411) The route information receiving unit 1252 determines whether or not the route information has been received. If the route information is received, the process goes to step S411. If the route information is not received, the process returns to step S410.

  (Step S412) The related map information transmission unit 1243 and the like perform a process of transmitting map information. It returns to step S401. Such map information transmission processing will be described using the flowchart of FIG.

  Further, in the flowchart of FIG. 5, although the route information receiving unit 1252 receives the route information, the route search may be performed in the terminal device 12 to obtain the route information.

  Further, in the flowchart of FIG. 4, the processing is ended by an interruption of power off or processing end.

  Next, the map information transmission process of step S412 will be described using the flowchart of FIG.

  (Step S501) The determination unit 1233 acquires attribute information of one or more pieces of map information corresponding to the route information. Note that the one or more pieces of map information corresponding to the route information are one or more pieces of map information including each route indicated by the route information. Moreover, the map information corresponding to route information is related map information. Further, the attribute information of the map information is, for example, version information of the map information, information on the update date / time of the map information, and the like. Here, it is preferable that the determination unit 1233 acquires one or more sets of map identifiers and attribute information for identifying one or more pieces of map information. Here, the determination unit 1233 may acquire only one or more map identifiers that identify one or more pieces of map information corresponding to the route information.

  (Step S502) The determination unit 1233 inquires the in-vehicle device 13 about necessary map information using the attribute information of one or more pieces of map information acquired in step S501. The process of inquiring may be any process as long as it is a process for determining map information that needs updating. In addition, the determination unit 1233 may inquire of the on-vehicle apparatus 13 of necessary map information using the one or more map identifiers acquired in step S501.

  For example, the determination unit 1233 transmits, to the on-vehicle apparatus 13, an inquiry instruction having a set of one or more map identifiers and attribute information acquired in step S501. And the judgment part 1233 receives 0 or 1 or more map identifiers which need the update from the vehicle-mounted apparatus 13, for example.

  In addition, the determination unit 1233 transmits, to the on-vehicle apparatus 13, for example, an inquiry instruction having one or more map identifiers acquired in step S501. Then, the determination unit 1233 receives, for example, one or more pieces of attribute information corresponding to one or more transmitted map identifiers from the in-vehicle apparatus 13. Then, the determination unit 1233 compares the attribute information of the one or more pieces of map information acquired in step S501 with the received one or more pieces of attribute information, and 0 or 1 of (old) map information that needs updating. Get the above map identifiers.

  (Step S503) The determination unit 1233 substitutes 1 for the counter i.

  (Step S504) The determining unit 1233 determines whether or not the ith related map information corresponding to the route information exists. If the i-th related map information exists, the process goes to step S505, and if the i-th related map information does not exist, the process returns to the upper level processing. Note that the determination of whether or not the i-th related map information exists may be a determination of whether or not the i-th map identifier exists.

  (Step S505) The determination unit 1233 determines whether it is necessary to update the map information of the in-vehicle apparatus 13 corresponding to the i-th related map information. If it is determined that the update is necessary, the process proceeds to step S506, and if it is determined that the update is not necessary, the process proceeds to step S507.

  (Step S506) The related map information acquisition unit 1234 acquires the i-th related map information from the terminal storage unit 121. Then, the related map information transmission unit 1243 transmits the i-th related map information to the in-vehicle device 13.

  (Step S507) The determination unit 1233 increments the counter i by one. The process returns to step S504.

  In the flowchart of FIG. 5, the determination process of the determination unit 1233 may be omitted. In such a case, the related map information acquisition unit 1234 acquires, from the terminal storage unit 121, all pieces of map information corresponding to the route information. Then, the related map information transmission unit 1243 transmits all the acquired map information to the on-vehicle apparatus 13.

  (Step S601) The in-vehicle receiving unit 134 determines whether or not the destination information is received from the terminal device 12. If the destination information is received, the process goes to step S602. If the destination information is not received, the process goes to step S609.

  (Step S602) The in-vehicle processing unit 133 acquires current location information indicating the current location.

  (Step S603) The in-vehicle processing unit 133 performs route search using the current location information acquired in step S602 and the destination information received in step S601, and acquires one or more route information. Here, the in-vehicle processing unit 133 is a plurality of pieces of route information, and it is preferable to acquire various pieces of route information.

  (Step S604) The in-vehicle transmission unit 135 transmits the one or more pieces of route information acquired in step S603 to the terminal device 12.

  (Step S605) The in-vehicle receiving unit 134 determines whether or not there is an inquiry from the terminal device 12. If there is an inquiry, the process goes to step S606. If there is no inquiry, the process returns to step S605.

The on-vehicle transmission unit 135 transmits, for example, one or more pairs of the map identifier and the attribute information to the terminal device 12.

  (Step S608) In response to the transmission of the one or more attribute information, the in-vehicle reception unit 134 determines whether or not the one or more pieces of related map information are received from the terminal device 12. If the map information is received, the process goes to step S609; otherwise, the process goes to step S610. Here, usually, a sufficient time is required for receiving the map information.

  (Step S609) The in-vehicle processing unit 133 stores the one or more pieces of related map information received in step S608 in the in-vehicle storage unit 131.

  (Step S610) The in-vehicle processing unit 133 performs route search using the map information stored in the in-vehicle storage unit 131, and acquires one or more route information.

  (Step S611) The in-vehicle processing unit 133 determines whether or not the route search result in Step S603 is the same as the route search result in Step S610. If they are the same, the process returns to step S601; otherwise, the process returns to step S604. In addition, when it is the same, usually, route guidance is started.

  (Step S612) The in-vehicle reception unit 134 determines whether one or more pieces of map information have been received from the terminal device 12. When one or more pieces of map information are received, the process goes to step S613. When one or more pieces of map information are not received, the process goes to step S614.

  (Step S613) The in-vehicle processing unit 133 stores the one or more pieces of map information received in step S612 in the in-vehicle storage unit 131. The process returns to step S601.

  (Step S614) The on-vehicle transmission unit 135 determines whether or not to transmit a start command. If it is determined that the activation instruction is to be transmitted, the process proceeds to step S615. If it is determined that the activation instruction is not transmitted, the process proceeds to step S616. The on-vehicle transmission unit 135 receives an instruction to receive destination information, to receive input of destination information, or to reject transmission of a start command from the terminal device 12, for example, after the on-vehicle apparatus 13 has started up. It is determined that the activation instruction is to be transmitted until

  In the flowchart of FIG. 6, the terminal processing unit 123 may automatically delete the map information stored in the on-vehicle storage unit 131 after the route guidance is completed. As a result, it is possible to prevent map information from being illegally copied to a plurality of in-vehicle devices 13. The terminal processing unit 123 may determine that the route guidance has ended by detecting arrival at the destination indicated by the destination information, or detecting that the engine has been turned off, etc. It may be determined that the route guidance has ended.

  In the flowchart of FIG. 6, the process is ended by powering off or interruption for aborting the process.

Of the two specific examples, specific example 1 transmits the map information used in the in-vehicle device 13 from the terminal device 12 to the in-vehicle device 13 without determining whether or not the map information of the in-vehicle device 13 is the latest. It is an example. Specific example 2 is an example in which, when the map information of the in-vehicle device 13 is not the latest, the map information in a range that is not the latest is transmitted from the terminal device 12 to the in-vehicle device 13.
(Specific example 1)

It returns to step S1301. Since the route guidance technique is a known technique, detailed description thereof is omitted.

  In the flowchart of FIG. 13, the in-vehicle device 23 may determine map information that needs to be updated. That is, for example, the on-vehicle receiving unit 234 receives one or more pairs of the map identifier and the attribute information corresponding to the received route information. Then, the in-vehicle processing unit 233 acquires attribute information of the map information identified by the received one or more map identifiers from the in-vehicle storage unit 131.
