At S13, CPU 41 reads the distinguishes data that is received from RAM 12, and is the cartographic information of latest edition with the map information update of range of distribution in the navigation map information 38.
Then, at S14, CPU 41 checks the renewal of the cartographic information of range of distribution in the navigation map information 38, and judges in upgrading cartographic information whether have any mistake.When not having mistake in the renewal cartographic information of range of distribution in navigation map information 38, more specifically, when the renewal success of the cartographic information of range of distribution (S14: be), the process that CPU 41 carries out among the S15.At S15, CPU 41 reads out in the distribution ID that receives the S12 from RAM 42, by send to distribute ID and in above S11 to map information distribution center 3 send in order to discern the navigation ID of above-mentioned navigator 2, upgrade successfully to map information distribution center 3 notice navigation map information 38, finish correlated process then.
For example, when there are not mistake in the block ID A of range of distribution in navigation map information 38 and the map information update among the B (S14: be), CPU 41 by the distribution ID T0001 that is sent in S12 and receives and in above S11 to map information distribution center 3 send in order to discern the navigation ID 1001 of above-mentioned navigator 2, upgrade successfully to map information distribution center 3 notice navigation map information 38, finish correlated process then.
Simultaneously, when mistake appears in the cartographic information of the range of distribution in upgrading navigation map information 38, more specifically, when the map information update of range of distribution is failed (S14: not), the process that CPU 41 carries out among the S16.At S16, CPU 41 by only be sent among the above S11 to map information distribution center 3 send in order to discern the navigation ID of above-mentioned navigator 2, upgrade failure to map information distribution center 3 notice navigation map information 38, finish correlated process then.
For example, CPU 41 by only be sent among the above S11 to map information distribution center 3 send in order to discern the navigation ID 1001 of above-mentioned navigator 2, upgrade failure to map information distribution center 3 notice navigation map information 38, finish correlated process then.
Simultaneously, as shown in Figure 4, when receiving at S116 that the navigation map information 38 that sends from navigator 2 is upgraded successfully or during the notice of failing, the CPU 11 in map information distribution center 3 stores above-mentioned notice into RAM 12, carries out the process among the S117 then.
At S117, CPU 11 reads notice once more from RAM 12, and judges whether the renewal of the navigation map information 38 in navigator 2 is successful, more specifically, judges whether to receive and distributes ID and the ID that navigates.When not receiving distribution ID and navigation ID, more specifically, (S117: not), CPU 11 judgements are failed by the renewal of the navigation map information 38 in the navigator 2 of above-mentioned navigation ID identification, and finish correlated process when only receiving navigation ID.
Therefore, for example, when above-mentioned navigation ID was 1001, the navigation corresponding with the navigator 2 of navigation ID 1001 identification upgraded historical information 53 (referring to Fig. 6) and do not upgraded.
Simultaneously, when receiving distribution ID and navigation ID (S117: be), CPU 11 judges by the renewal of the navigation map information 38 in the navigator 2 of above-mentioned navigation ID identification successful, and carries out the process among the S118.
At S118, CPU 11 reads out in the distribution ID that stores the S116 once more from RAM 12, and reads the allocation manager information corresponding with distributing ID from allocation manager information database 19, and stores them into RAM 12.CPU 11 will renew by the renewal version that stored history in the historical information database 15 is upgraded in the navigation of the navigation ID appointment of storing among the S116 for RAM 12 in each assign road kind of storage and the corresponding version of block ID of allocation manager information, then they are stored once more into navigation and upgrade historical information database 15, and finish correlated process.Thereby it is can be reliably consistent with the current version information of storage in the navigation map information 38 in the navigator 2 of navigation ID appointment for the renewal historical data of storage in the renewal historical data base 15 of navigation ID appointment.
With reference to Fig. 8 and 9, be described in the example that historical information 53 is upgraded in the renewal navigation shown in Fig. 6.Fig. 9 is the allocation manager information 54 that illustrates based on shown in Fig. 8, upgrades the chart of an example of historical information 53 in the navigation of having upgraded shown in Fig. 6.
For example, when receiving distribution ID T00001 and navigation ID 1001 at above-mentioned S116, the allocation manager information 54 (referring to Fig. 8) that CPU11 stores from allocation manager information database 19 is read and high standard, high standard and the common corresponding version 2 of assign road kind, 2 and 2, and block ID A, B and the B corresponding, and store them into RAM 12 with above-mentioned distribution ID T00001.
As shown in Figure 9, CPU 11 renews (renew) one-tenth and high standard, high standard and the common corresponding version 2 of assign road kind by the version of the renewal historical data 53 (referring to Fig. 6) of storage in the renewal historical data base 15 of navigation ID 1001 appointments of will store among the S116,2 and 2, and block ID A, B and the B of storage in the allocation manager information 54 (referring to Fig. 8) of storage in RAM 12, create navigation and upgrade historical information 55, and store them into navigation once more and upgrade historical information database 15, finish correlated process then.
Thereby it is can be reliably consistent with the current version information of storage in the navigation map information 38 in the navigator 2 of navigation ID 1001 appointments for the renewal historical data 55 of upgrading navigation ID 1001 appointments of storage in the historical data base 15.
Next, in having the cartographic information distribution system 1 of said structure, describe with reference to Figure 10 to Figure 15, when the navigation map information 38 in the navigator 2 is updated based on the renewal cartographic information by the area, navigation in the map information distribution center 3 is upgraded the navigation of storage in the historical information database 15 and upgraded the process that historical information is upgraded, described renewal cartographic information is assigned to PC5 and records CD-ROM 6 from above-mentioned map information distribution center 3.
At first, with reference to Figure 10 to 12 the storage medium recorded process of being carried out by map information distribution center 3 and PC 5 of upgrading cartographic information on CD-ROM 6 by the area record is described.

E ", the assign road kind " high standard; common; high standard; ... narrow street ", distinguishes data " 2A1; 2A2; 2B1; ... 2E1 ", during with distribution ID P00001, CPU 71 among the PC 5 creates by the area and upgrades cartographic information 62, it is stored as P00001 and distributes ID, " A; A; B; ... E " be stored as block ID successively, " high standard; common; high standard; ... narrow street " be stored as the assign road kind successively, " 2A1; 2A2; 2B1; ... 2E1 " be stored as distinguishes data successively, and on CD-ROM6, press the area record via register 5A and upgrade cartographic information 62, reading by the CPU in the navigator 2 41 via reader 28.
Next, based on the renewal cartographic information that is recorded in by the area on the CD-ROM 6 that is equipped with in the storage medium recorded process shown in Figure 10, when upgrading the navigation map information 38 in the navigator 2, with reference to Figure 13 to 15, the renewal process that historical information is upgraded in the navigation of storing in the historical information database 15 is upgraded in the navigation that is described in the above-mentioned map information distribution center 3.
Figure 13 is the CD-ROM 6 that is equipped with in via the storage medium recorded process shown in Figure 10 when upgrading navigation map information 38 in the navigator 2, and the process flow diagram of the renewal process of historical information is upgraded in the navigation that storage in the historical information database 15 is upgraded in the navigation in above-mentioned map information distribution center 3.In the ROM 43 and ROM 13 in map information distribution center 3 of the described procedure stores of the process flow diagram among Figure 13 in navigator 2, and by each CPU 41 and 11 execution.
As shown in figure 13, at S31, the CPU 41 in the navigator 2 reads block ID, assign road kind and the distinguishes data corresponding with block ID via reader 28 from the renewal cartographic information that writes down by the area on CD-ROM 6, and stores them into RAM 42.
At S32, whether CPU 41 judges in the navigation map information 38 corresponding with each assign road kind of block ID of storage among the RAM 42, more Zao than the latest edition of each part distinguishes data of storage among the above-mentioned RAM 42 by the current version of the cartographic information of regional assigned region.When this version early the time, CPU 41 upgrades cartographic information based on the corresponding distinguishes data of latest edition.
Describe an example of the navigation map information of in navigator 2, being upgraded via CD-ROM 6 38 with reference to Figure 14, as shown in figure 12, upgrade cartographic information 62 and be recorded among the CD-ROM6 by the area.
Figure 14 is a diagrammatic sketch of describing an example of the navigation map information of being upgraded via CD-ROM 6 38 in navigator 2, as shown in figure 12, upgrades cartographic information 62 and is recorded among the CD-ROM 6 by the area.
As shown in figure 14, CPU 41 is at first based on the renewal cartographic information of reading and be stored in from CD-ROM 6 RAM 42 by the area 62, judge with navigation map information 38 in block ID A in the corresponding version of high-level assign road kind whether be version 2.When this version is not version 2, CPU 41 will be a version 2 with high-level assign road kind corresponding map information updating among the block ID A in the navigation map information 38 based on the distinguishes data 2A1 of storage in RAM 42.
Next, CPU 41 is based on the renewal cartographic information 62 that is stored among the RAM 42 by the area, judge with navigation map information 38 in block ID A in the corresponding version of common assign road kind whether be version 2.When this version is version 2, be not updated in the cartographic information of assign road kind common among the block ID A in the navigation map information 38.CPU 41 is with based on the similar fashion that is stored among the RAM 42 by the renewal cartographic information 62 in area, be updated in the cartographic information of high standard among the block ID B in the navigation map information 38 and common assign road kind respectively according to distinguishes data 2B1,2B2,2C1 to 2C3 and 2E1, the cartographic information of the assign road kind in the high standard among the block ID C, common and narrow street, and the cartographic information of the assign road kind in the narrow street among the block ID E.
At S33, CPU 41 checks in the navigation map information of upgrading 38 renewal by the cartographic information of regional assigned region in above S32, and judges in upgrading cartographic information whether have any mistake.When in navigation map information 38 by existing in the map information update of regional assigned region when wrong, more specifically, (S33: not), CPU 41 fails to the user notification map information update, and finishes correlated process when by the failure of the map information update in the regional assigned region.
Simultaneously, when not having mistake in the renewal by the cartographic information of regional assigned region in navigation map information 38, more specifically, and when by the success of the map information update in the regional assigned region (S33: be), the process that CPU 41 carries out among the S34.In S34, CPU 41 reads out in the distribution ID of storage among the CD-ROM 6, and is stored to RAM 42.
For example, as CD-ROM 6 during as shown in figure 12 by regional storage update cartographic information 62, CPU 41 reads and distributes ID P00001, and is stored to RAM 42.
At S35, CPU 41 reads once more from RAM 42 and distributes ID, by send to distribute ID and in above S11, be sent to map information distribution center 3 and discerned the navigation ID of above-mentioned navigator 2, via the renewal of CD-ROM 6, finish correlated process then to map information distribution center 3 notice navigation map information 38.
For example, CPU 41 by being sent among the RAM 42 among the S34 storage distribution ID P00001 and in order to discern above-mentioned navigator 2 and in above S11, to be sent to the navigation ID 1001 of map information distribution center 3, via the renewal of CD-ROM 6, finish correlated process then to map information distribution center 3 notice navigation map information 38.
Simultaneously, as shown in figure 13, at S411, the CPU 11 in the map information distribution center 3 judges whether to receive the notice of upgrading navigation map information 38 from navigator 2, more specifically, judges whether to receive and distributes ID and the ID that navigates.(S411: not), CPU 11 finishes correlated process when distributing ID and navigating ID when not receiving.
Therefore, for example, do not upgrade the navigation corresponding and upgrade historical information 53 (referring to Fig. 6) with the navigator 2 of navigation ID 1001 appointments.
Simultaneously, when receiving distribution ID and navigation ID (S411: be), CPU 11 judges that the navigation map information 38 in the navigator 2 of above-mentioned navigation ID appointment has been updated, and will distribute the ID and the ID that navigates to store RAM 12 into, carries out the process among the S412 then.
At S412, CPU 11 reads once more from RAM 12 and distributes ID, reads the PC allocation manager information corresponding with distributing ID from allocation manager information database 19, and stores them into RAM12.
At S413, the renewal historical data version that CPU 11 upgrades storage in the historical information database 15 with the navigation of the navigation ID appointment of storing among the S411 renew become with RAM 12 in each assign road kind and the corresponding version of block ID in the PC allocation manager information of storage, then they are stored once more into navigation and upgrade historical information database 15, and finish correlated process.Thereby the renewal historical data of storage is can be reliably consistent with the current version information of storage in the navigation map information 38 in the navigator 2 of navigation ID appointment in the renewal historical data base 15 of navigation ID appointment, and wherein the renewal cartographic information based on storage among the CD-ROM 6 has upgraded navigation map information.
Be described in the example that historical information 53 is upgraded in the renewal navigation shown in Fig. 6 with reference to Figure 11 and 15.Figure 15 illustrates based in the PC allocation manager information 61 shown in Figure 11, upgrades the chart of an example of historical information 53 in the navigation of having upgraded shown in Fig. 6.
For example, when in above-mentioned S411, receiving distribution ID P00001 and navigation ID 1001, the PC allocation manager information 61 that CPU11 stores from allocation manager information database 19 read with block ID data " A; A; B; ... E " and assign road kind " high standard; common; high standard, ... narrow street " corresponding version " 2,2,2, ... 2 " (referring to Figure 11); and store them into RAM 12, wherein block ID data " A, A, B, ... E " and assign road kind " high standard, common, high standard, ... narrow street " corresponding with above-mentioned distribution ID P0001.
As shown in figure 15, the version of CPU 11 by the renewal historical data 53 (referring to Fig. 6) of storage in the renewal historical data base 15 of navigation ID 1001 appointments of will store among the S411 renew for RAM 12 in storage block ID " A, A, B ... E " and the assign road kind " high standard, common, high standard ... narrow street " corresponding version " 2,2,2 ... 2 ", and they are stored into once more upgrade historical data base 15, finish correlated process then.
Thereby the renewal historical data 63 by navigation ID 1001 appointments of storage can wherein be upgraded navigation map information based on the renewal cartographic information 62 (referring to Figure 12) by the area storage among the CD-ROM 6 reliably with consistent by the current version information of storage in the navigation map information 38 in the navigator 2 of navigation ID 1001 appointments in upgrading historical data base 15.
As mentioned above, in the map information distribution center 3 of first embodiment of the invention, when receiving coordinate data and former flag and specifying the navigation ID of navigator 2, under the situation that former flag is opened, CPU 11 is that the first area at center is set to the range of distribution with the coordinate data of original position of registration, under the situation that former flag is closed, CPU 11 is that the second area at center is set to range of distribution (S11 and S111) with the coordinate data of destination.CPU 11 by upgrade from navigation that historical information database 15 is read and the navigation 2 of the ID appointment of navigating the history-sensitive data of renewal of range of distribution, with the high standard in navigator 2, in the assign road kind in common and narrow street in order to the about current version of square each block (grid) of 2.5km in the assigned region (area subject to distribute), and read the distinguishes data filename from distinguishes data management database 18, described distinguishes data table of file name is shown in the distinguishes data of latest edition in each the assign road kind of block in the range of distribution, extract the distinguishes data between the latest edition of each block in current version in the navigator 2 and the range of distribution, (S113).Next, CPU11 selects in order to discern the distribution ID of the distinguishes data of being extracted, and will comprise the allocation manager information of distributing ID, the block ID of each block of the expression range of distribution corresponding with distinguishes data, store allocation manager information database 19 into the renewal version of assign road kind in each block ID, navigation device 2 sends and distributes ID and distinguishes data (S114 to S115) then.
Simultaneously, when upgrading navigation map information 38 based on the distinguishes data that received, the CPU 41 in the navigator 2 sends the distribution ID that received and in order to discern the navigation ID (S12 to S16) of above-mentioned navigator 2 to map information distribution center 3.
When receiving distribution ID and navigation ID, navigation map information 38 in the CPU 11 judgement navigator 2 in the map information distribution center 3 has been upgraded, and by read the allocation manager information corresponding from allocation manager information database 19 with distributing ID, and the version of the renewal historical data of storage in upgrading historical data base 15 of the ID appointment of will navigating renew become with allocation manager information in assign road kind and the corresponding version of block ID, come the renewal historical data by navigation ID appointment of storage in upgrading historical data base 15 is upgraded (S116 to S118).
When receiving coordinate data and former flag and navigation ID from navigator 2, map information distribution center 3 can be by reading the distinguishes data filename from distinguishes data management database 18, this distinguishes data filename is in order to the distinguishes data of the latest edition of the assign road kind of each block in the expression range of distribution, be extracted in the distinguishes data between the latest edition of the current version of the navigator in each block 2 in the range of distribution and each assign road kind, and they are sent to navigator 2, simultaneously with the high standard of the foursquare block of about 2.5km (grid), assign road kind common and narrow street is the version information that unit manages the navigation map information 38 of storage in each navigator 2.When the map information update in the high standard assign road kind in the data recorder 22 of navigator 2 in each block of the navigation map information 38 of storage becomes latest edition, national road of described high standard assign road kind and national highway, rapid transit, one or two digits etc. is relevant, map information distribution center 3 can be extracted and navigation device 2 transmissions are upgraded relevant minimum distinguishes data with the assign road kind in common and narrow street, and does not comprise the cartographic information relevant with high standard.Thereby can reduce amount of communication data with navigator 2.
When navigator 2 during, only need to send former flag, coordinate data and navigation ID as the update request data to map information distribution center 3 from navigator 2 from map information distribution center 3 request distinguishes data.Thereby can further reduce the amount of communication data that is used for upgrading the navigation map information 38 of navigator 2 and sends.
When receiving distribution ID that is sent out with distinguishes data and the navigation ID that specifies navigator 2, map information distribution center 3 is by reading the allocation manager information corresponding with distributing ID from allocation manager information database 19, and the renewal historical data version by navigation ID appointment that will upgrade in the historical data base 15 storage renews each the block ID and the corresponding version of assign road kind that become with the allocation manager data, upgrades.Thereby the renewal history of the version information in corresponding each the assign road kind of each block ID that can accurately manage the navigation map information 38 of storage in the data recorder 22 with navigator 2, and the version information in each assign road kind that accurately each block ID of the navigation map information 38 of current storage is corresponding in management and the navigator 2.
Described in detail as mentioned, in the cartographic information distribution system 1 of first embodiment of the invention, when receiving coordinate data and former flag and specifying the navigation ID of navigator 2, under the situation that former flag is opened, the CPU 11 of map information distribution center 3 is that the first area at center is set to the range of distribution with the coordinate data of original position of registration, under the situation that former flag is closed, CPU 11 is that the second area at center is set to range of distribution (S11 and S111) with the coordinate data of destination.CPU 11 by upgrade from navigation that historical information database 15 is read and the navigation 2 of the ID appointment of navigating the history-sensitive data of renewal of range of distribution, extract the distinguishes data between the latest edition of each block of current version in the navigator 2 and range of distribution, and from distinguishes data management database 18 extraction distinguishes data filenames, it is in order to the distinguishes data (S113) of the latest edition of block in the expression range of distribution.Next, CPU 11 selects in order to discern the distribution ID of the distinguishes data of being extracted, and will comprise that the allocation manager information and the distinguishes data of distributing ID store allocation manager information database 19 into, navigation device 2 sends and distributes ID and distinguishes data (S114 to S115) then.
Simultaneously, when upgrading navigation map information 38 based on the distinguishes data that is received, the CPU 41 in the navigator 2 sends the distribution ID that received and in order to discern the navigation ID (S12 to S16) of above-mentioned navigator 2 to map information distribution center 3.
When receiving distribution ID and navigation ID, navigation map information 38 in the CPU 11 judgement navigator 2 in the map information distribution center 3 has been upgraded, and, come to upgrade (S116 to S118) to upgrading the renewal historical data by navigation ID appointment of storing in the historical data base 15 by read the allocation manager information corresponding from allocation manager information database 19 with distributing ID.
When navigator 2 when cartographic informations are upgraded in map information distribution center 3 request, only need to send former flag, coordinate data and the navigation ID that is set to open or close to map information distribution center 3 from navigator 2.Thereby can be reduced to the navigation map information of upgrading in the navigator 2 38 and the amount of communication data that sends.
When receiving distribution ID that is sent out with distinguishes data and the navigation ID that specifies navigator 2, map information distribution center 3 is updated in the renewal historical data by navigation ID appointment of upgrading storage in the historical data base 15 by read the allocation manager information corresponding with distributing ID from allocation manager information database 19.Thereby can accurately manage the renewal history of the navigation map information 38 of storage in the data recorder 22 of navigator 2, and the version information of accurately managing the navigation map information 38 of current storage in navigator 2.
