Meanwhile, as shown in Figure 4, when receiving distinguishes data via communication facilities 27 from map information distribution center 3 and distribute ID in S12, distinguishes data and distribution ID are stored in RAM 42 by the CPU 41 in navigator 2.
Read the distinguishes data received at S13, CPU 41 from RAM 12, and be the cartographic information of latest edition by the map information update of range of distribution in navigation map information 38.
Then, check the renewal of the cartographic information of range of distribution in navigation map information 38 at S14, CPU 41, and judge whether there is any mistake in renewal cartographic information.When in navigation map information 38 range of distribution renewal cartographic information in there is not mistake time, more specifically, when being updated successfully of cartographic information of range of distribution (S14: yes), CPU 41 carries out the process in S15.At S15, CPU 41 reads from RAM 42 the distribution ID received among S12, by send distribute ID and in above S11 to map information distribution center 3 send the navigation ID in order to identify above-mentioned navigator 2, notify that navigation map information 38 is updated successfully to map information distribution center 3, then complete correlated process.
Such as, when in navigation map information 38 range of distribution block ID A and B in map information update there is not mistake time (S14: yes), CPU 41 by be sent in S12 receive distribution ID T0001 and in above S11 to map information distribution center 3 send the navigation ID 1001 in order to identify above-mentioned navigator 2, notify that navigation map information 38 is updated successfully to map information distribution center 3, then complete correlated process.
Meanwhile, when there is mistake at the cartographic information upgrading the range of distribution in navigation map information 38, more specifically, when the map information update failure of range of distribution (S14: no), CPU 41 carries out the process in S16.At S16, CPU 41 by being only sent in above S11 to the navigation ID in order to identify above-mentioned navigator 2 that map information distribution center 3 sends, notifying that navigation map information 38 upgrades failure to map information distribution center 3, then completing correlated process.
Such as, CPU 41 is by being only sent in above S11 to the navigation ID 1001 in order to identify above-mentioned navigator 2 that map information distribution center 3 sends, notify that navigation map information 38 upgrades failure to map information distribution center 3, then complete correlated process.
Meanwhile, as shown in Figure 4, when receive at S116 the navigation map information 38 sent from navigator 2 be updated successfully or the notice of failure time, above-mentioned notice is stored into RAM 12 by the CPU 11 in map information distribution center 3, then carries out the process in S117.
Again read notice at S117, CPU 11 from RAM 12, and judge that whether the renewal of the navigation map information 38 in navigator 2 is successful, more specifically, judge whether to receive and distribute ID and navigation ID.When not receiving distribution ID and navigation ID, more specifically, when only receiving navigation ID (S117: no), CPU 11 judges the renewal failure of the navigation map information 38 in the navigator 2 identified by above-mentioned navigation ID, and completes correlated process.
Therefore, such as, when above-mentioned navigation ID is 1001, the navigation corresponding with the navigator 2 that navigation ID 1001 identifies upgrades historical information 53 (see Fig. 6) and does not upgrade.
Meanwhile, distribute ID and (S117: yes) during navigation ID when receiving, CPU 11 judges the renewal success of the navigation map information 38 in the navigator 2 identified by above-mentioned navigation ID, and carries out the process in S118.
Again read from RAM 12 the distribution ID stored among S116 at S118, CPU 11, and read the allocation manager information corresponding with distributing ID from allocation manager information database 19, and they are stored into RAM 12.The renewal version that the navigation of being specified by the navigation ID stored in S116 is upgraded the historical data stored in historical information database 15 by CPU 11 renew for store in RAM 12 each distribute version corresponding to the block ID of road category and allocation manager information, then they are stored into again navigation and upgrade historical information database 15, and complete correlated process.Thus can be reliably consistent with the current version information stored in the navigation map information 38 in the navigator 2 of specifying at the ID that navigates for the renewal historical data stored in the navigation ID renewal historical data base 15 of specifying.
With reference to Fig. 8 and 9, be described in the example that the renewal navigation shown in Fig. 6 upgrades historical information 53.Fig. 9 illustrates the allocation manager information 54 based on shown in Fig. 8, and the navigation upgraded in figure 6 upgrades the chart of an example of historical information 53.
Such as, when receiving distribution ID T00001 and navigation ID 1001 at above-mentioned S116, the allocation manager information 54 (see Fig. 8) that CPU11 stores from allocation manager information database 19 reads the version 2 corresponding with high standard, high standard and common distribution road category, 2 and 2, and block ID A, B and the B corresponding with above-mentioned distribution ID T00001, and they are stored into RAM 12.
As shown in Figure 9, the version that CPU 11 passes through the renewal historical data 53 (see Fig. 6) stored in the renewal historical data base 15 of being specified by the navigation ID 1001 stored in S116 renews the version 2 that (renew) becomes corresponding with high standard, high standard and common distribution road category, 2 and 2, and block ID A, B and B of storing in the allocation manager information 54 (see Fig. 8) stored in RAM 12, create navigation and upgrade historical information 55, and they are stored into again navigation and upgrade historical information database 15, then complete correlated process.
Thus can be reliably consistent with the current version information stored in the navigation map information 38 in the navigator 2 of specifying at the ID 1001 that navigates for upgrading the renewal historical data 55 that the navigation ID 1001 that stores in historical data base 15 specifies.
Next, in the cartographic information distribution system 1 with said structure, describe with reference to Figure 10 to Figure 15, when the navigation map information 38 in navigator 2 is updated based on the renewal cartographic information by area, to the process that the navigation renewal historical information stored in the navigation renewal historical information database 15 in map information distribution center 3 upgrades, described renewal cartographic information has been assigned to PC 5 from above-mentioned map information distribution center 3 and has been recorded to CD-ROM 6.
First, the storage medium recorded process recording renewal cartographic information on CD-ROM 6 by area performed by map information distribution center 3 and PC 5 is described with reference to Figure 10 to 12.
Figure 10 is in the cartographic information distribution system 1 of first embodiment of the invention, the process flow diagram recording the storage medium recorded process upgrading cartographic information on CD-ROM 6 by area performed by cartographic information distribution system 3 and PC 5.Program shown in process flow diagram in Figure 10 is stored in the ROM 13 in map information distribution center 3 and ROM 73 (not shown) in PC 5, and is performed by the CPU 11 in map information distribution center 3 and CPU 71 (not shown) in PC 5.
As shown in Figure 10, at S211, first CPU 71 in PC 5 sends in order to represent by user-selected area name (such as to map information distribution center 3, Tokyo, Osaka, Hokkaido, love county magistrate etc.) area data and regional unit requests signal, described regional unit requests signal upgrades the information (distinguishes data) of the cartographic information in area selected by each in order to request.
Simultaneously, as shown in Figure 10, when receiving to represent the area data in area and regional unit requests signal via center to center communications equipment 16 in S311, described regional unit requests signal is as the request of the lastest imformation (distinguishes data) of the cartographic information sent by area from PC 5, and regional information is stored into RAM 12 by the CPU 11 in map information distribution center 3.
CPU 11 reads area data again from RAM 12, the region being set in the area that above-mentioned area data is specified distribute by area is to extract distinguishes data, then read the distinguishes data management information of the latest edition of each block the region (range of distribution) distributed by area from distinguishes data management database 18 as mentioned above, and they are stored into RAM 12.Then, CPU 11 reads the distinguishes data corresponding with the distinguishes data filename in the distinguishes data management information stored RAM 12 from upgrading cartographic information 17, and they are stored into RAM 12.
Such as, when the area data read from RAM 12 is about X area, the region (range of distribution) that X area is set to distribute by area by CPU 11 is to extract distinguishes data.When in the region (range of distribution) distributed, approximately the foursquare block of 2.5km (grid) is A, B, C, D and E (see Figure 14), it is the distinguishes data management information (version, block ID, distribute road category and distinguishes data filename) of the latest edition that each block of A to E is corresponding that the distinguishes data management information 52 (see Fig. 5) that CPU 11 stores from distinguishes data management database 18 reads successively with block ID, and they are stored into RAM 12.Therefore, CPU 11 by " version 2, block A, high standard, 2A1 ", " version 2, block A, common, 2A2 " ... the data of " version 2, block E, narrow street, 2E1 " are stored into RAM 12 as the distinguishes data management information of latest edition.Then, CPU 11 reads and distinguishes data filename 2A1, the 2A2 in the distinguishes data management information that stores RAM 12, distinguishes data that 2B1 ... 2E1 is corresponding from upgrading cartographic information 17, and they are stored into RAM 12.
For the purpose of simplifying the description, the foursquare block of 2.5km about in the X area being set to the region (range of distribution) distributed by area is set to 5 blocks that block ID is A to E.Although area data to be set to an area in such as X area, also multiple area can be set to the region (range of distribution) distributed.
Select the distribution ID in order to identify the distinguishes data extracted by area at S312, CPU 11, and be stored to RAM 12.
At S313, CPU 11 creates PC allocation manager information, and be stored to the allocation manager information of allocation manager information database 19 as the distinguishes data of distributing to PC 5 by area in order to management, wherein said PC allocation manager information comprises: in order to identify the distribution ID of the distinguishes data extracted by area, in order to represent the block ID of each block, in RAM 12 store range of distribution in each block latest edition distinguishes data management information in distribution road category and version.
An example of the PC allocation manager information stored in allocation manager information database 19 is described in reference to Figure 11.Figure 11 illustrates in the S313 of the process flow diagram shown in Figure 10, the chart of an example of the PC allocation manager information 61 stored in allocation manager information database 19.
As shown in figure 11, CPU 11 selects P00001 as the distribution ID in order to identify the distinguishes data extracted in X area by area, and P00001 is stored as the distribution ID of PC allocation manager information 61.The latest edition of the distinguishes data management information in the X area that CPU 11 stores from RAM 12 reads block ID successively, distributes road category and version, as " version 2; block A; high standard; 2A1 ", " version 2; block A, common, 2A2 ", ... " version 2; block E, narrow street, 2E1 ", and by they being stored as successively block ID, distributing road category and the version of the PC allocation manager information 61 corresponding with distributing ID P00001, they are stored into allocation manager information database 19.
Therefore, store successively as the A of block ID as the PC allocation manager information 61, CPU 11 of being specified by distribution ID P00001, A, B ... the data of E, successively as distributing the high standard of road category, the data in common, the narrow street of high standard ..., and successively as the data 2 of version.
At S314, CPU 11 reads by the block ID by the distinguishes data management information of latest edition in each block in the region of area distribution arranged above-mentioned S311 from RAM 12 and distributes the distribution ID in order to identify distinguishes data by area extracted in road category, the distinguishes data corresponding with block ID and S312, then they are assigned to PC 5, and complete correlated process after the distribution.
Such as, CPU 11 reads X area by the distinguishes data management information in area from RAM 12, block ID A, A, B ... E, the distribution road category in high standard, common, the narrow street of high standard ..., with distinguishes data filename 2A1,2A2, distinguishes data 2A1,2A2,2B1 ... 2E1 that 2B1 ... 2E1 is corresponding with distribute ID P00001, then they are distributed to PC 5, and complete correlated process after the distribution.
Simultaneously, as shown in Figure 10, when S212 via communication facilities 27 from map information distribution center 3 receive by the distinguishes data management information in area block ID and distribute road category, the distinguishes data corresponding with block ID and in order to by regional identify the distribution ID of distinguishes data time, these data are stored into RAM 72 (not shown) by the CPU 71 in PC 5.
At S213, CPU 71 from RAM 72 read successively by the distinguishes data management information in area the block ID received and distribute road category, the distinguishes data corresponding with block ID and in order to specify the distribution ID of distinguishes data by area, and they are stored into CD-ROM 6 via register 5A by area, so that renewal cartographic information can be read as by the CPU 41 in navigator 2 by area via reader 28, then complete correlated process.
Example CD-ROM 6 upgrading cartographic information by area record is described in reference to Figure 12.Figure 12 illustrates in the S213 in process flow diagram shown in Fig. 10, and CD-ROM 6 upgrades by area record the chart of an example of cartographic information.
When as shown in figure 12, block ID " the A of the distinguishes data management information by area in X area is distributed from map information distribution center 3 to PC 5, A, B, ... E ", distribute road category " high standard, common, high standard, ... narrow street ", distinguishes data " 2A1, 2A2, 2B1, ... 2E1 ", during with distribution ID P00001, CPU 71 in PC 5 creates by area and upgrades cartographic information 62, P00001 is stored as and distributes ID by it, " A, A, B, ... E " be stored as block ID successively, " high standard, common, high standard, ... narrow street " be stored as distribution road category successively, " 2A1, 2A2, 2B1, ... 2E1 " be stored as distinguishes data successively, and on CD-ROM6, upgrade cartographic information 62 by area record via register 5A, can be read by the CPU 41 in navigator 2 via reader 28.
Next, based on the renewal cartographic information be recorded in by 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 navigator 2, with reference to Figure 13 to 15, the navigation be described in above-mentioned map information distribution center 3 upgrades the renewal process that the navigation stored in historical information database 15 upgrades historical information.
Figure 13 be the CD-ROM 6 that is equipped with in via the storage medium recorded process shown in Figure 10 to upgrade the navigation map information 38 in navigator 2 time, the navigation in above-mentioned map information distribution center 3 upgrades the process flow diagram that the navigation stored in historical information database 15 upgrades the renewal process of historical information.Program described in process flow diagram in Figure 13 is stored in the ROM 43 in the navigator 2 and ROM 13 in map information distribution center 3, and is performed by each CPU 41 and 11.
As shown in figure 13, at S31, the CPU 41 in navigator 2 reads block ID, distributes road category and the distinguishes data corresponding with block ID from CD-ROM 6 by the renewal cartographic information of area record via reader 28, and they are stored into RAM 42.
At S32, CPU 41 judges distributing in navigation map information corresponding to road category 38 with each of the block ID stored in RAM 42, and whether the current version of the cartographic information in the region distributed by area is more Zao than the latest edition of the every a part of distinguishes data stored in above-mentioned RAM 42.When this version comparatively early time, CPU 41 upgrades cartographic information based on the corresponding distinguishes data of latest edition.
Describe an example of the navigation map information 38 upgraded in navigator 2 via CD-ROM 6 with reference to Figure 14, as shown in figure 12, upgrade cartographic information 62 and be recorded in CD-ROM6 by area.
Figure 14 is the diagram of the example describing the navigation map information 38 upgraded in navigator 2 via CD-ROM 6, as shown in figure 12, upgrades cartographic information 62 and is recorded in CD-ROM 6 by area.
As shown in figure 14, CPU 41, first based on reading from CD-ROM 6 and being stored in the renewal cartographic information 62 by area in RAM 42, judges whether the version corresponding with high-level distribution road category in the block ID A in navigation map information 38 is version 2.When this version is not version 2, the map information update corresponding with high-level distribution road category in the block ID A in navigation map information 38, based on the distinguishes data 2A1 stored in RAM 42, is version 2 by CPU 41.
Next, CPU 41, based on the renewal cartographic information 62 be stored in by area in RAM 42, judges whether the version corresponding with distribution road category common in the block ID A in navigation map information 38 is version 2.When this version is version 2, do not upgrade the cartographic information of distribution road category common in the block ID A in navigation map information 38.CPU 41 is with based on the similar fashion be stored in by the renewal cartographic information 62 in area in RAM 42, respectively according to distinguishes data 2B1,2B2,2C1 to 2C3 and the high standard of 2E1 renewal in navigation map information 38 in block ID B and the cartographic information of common distribution road category, the cartographic information of the distribution road category in the high standard in block ID C, common and narrow street, and the cartographic information of the distribution road category in narrow street in block ID E.
Check the renewal by the cartographic information in the region of area distribution in the navigation map information 38 upgraded in above S32 at S33, CPU 41, and judge whether there is any mistake in renewal cartographic information.When there is mistake in the map information update in the region distributed by area in navigation map information 38, more specifically, when the map information update in the region distributed by area is failed (S33: no), CPU 41 informs the user map information update failure, and completes correlated process.
Simultaneously, by when there is not mistake in the renewal of the cartographic information in the region of area distribution in navigation map information 38, more specifically, when the map information update in the region distributed by area is successful (S33: yes), CPU 41 carries out the process in S34.In S34, CPU 41 reads the distribution ID stored in CD-ROM 6, and is stored to RAM 42.
Such as, when CD-ROM 6 is 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 again reads from RAM 42 and distributes ID, distribute ID by sending and in above S11, be sent to map information distribution center 3 and identify the navigation ID of above-mentioned navigator 2, notify the renewal of navigation map information 38 via CD-ROM 6 to map information distribution center 3, then complete correlated process.
Such as, CPU 41 is by being sent in the distribution ID P00001 that stores in the RAM 42 in S34 and in order to identify above-mentioned navigator 2 and be sent to the navigation ID 1001 of map information distribution center 3 in above S11, notify the renewal of navigation map information 38 via CD-ROM 6 to map information distribution center 3, then complete correlated process.
Meanwhile, as shown in figure 13, at S411, the CPU 11 in map information distribution center 3 judges whether to receive from navigator 2 notice upgrading navigation map information 38, more specifically, judges whether to receive and distributes ID and navigation ID.Distribute ID and (S411: no) during navigation ID when not receiving, CPU 11 completes correlated process.
Therefore, such as, do not upgrade the navigation corresponding with the navigator 2 that navigation ID 1001 specifies and upgrade historical information 53 (see Fig. 6).
Simultaneously, ID and (S411: yes) during navigation ID is distributed when receiving, CPU 11 judges that the navigation map information 38 in the navigator 2 of specifying at above-mentioned navigation ID is updated, and distribution ID and navigation ID is stored into RAM 12, then carries out the process in S412.
Again read distribution ID at S412, CPU 11 from RAM 12, read the PC allocation manager information corresponding with distributing ID from allocation manager information database 19, and they are stored into RAM12.
At S413, navigation that the navigation ID stored in S411 specifies by CPU 11 upgrades the renewal historical data version stored in historical information database 15 and renews into and to distribute road category and version corresponding to block ID with each in the PC allocation manager information stored in RAM 12, then they are stored into again navigation and upgrade historical information database 15, and complete correlated process.Thus the renewal historical data stored in the navigation ID renewal historical data base 15 of specifying can be reliably consistent with the current version information stored in the navigation map information 38 in the navigator 2 of specifying at the ID that navigate, the renewal cartographic information wherein based on storage in CD-ROM 6 upgrades navigation map information.
The example that the renewal navigation shown in Fig. 6 upgrades historical information 53 is described in reference to Figure 11 and 15.Figure 15 illustrates the PC allocation manager information 61 based on shown in fig. 11, and the navigation upgraded in figure 6 upgrades the chart of an example of historical information 53.
Such as, when receiving distribution ID P00001 and navigation ID 1001 in above-mentioned S411, the PC allocation manager information 61 that CPU11 stores from allocation manager information database 19 reads and block ID data " A, A, B, ... E " and distribute road category " high standard, common, high standard, ... narrow street " corresponding version " 2, 2, 2, ... 2 " (see Figure 11), and they are stored into RAM 12, wherein block ID data " A, A, B, ... E " and distribute road category " high standard, common, high standard, ... narrow street " corresponding with above-mentioned distribution ID P0001.
As shown in figure 15, CPU 11 by the version of the renewal historical data 53 (see Fig. 6) stored in renewal historical data base 15 that the navigation ID 1001 stored in S411 is specified renew for the block ID " A, A, B ... E " that stores in RAM 12 and the version " 2,2,2 ... 2 " that distributes road category " high standard, common, the narrow street of high standard ... " correspondence, and they are stored into again renewal historical data base 15, then complete correlated process.
Thus can be reliably consistent with the current version information stored in the navigation map information 38 in the navigator 2 of being specified by the ID 1001 that navigates in the renewal historical data 63 of being specified by navigation ID 1001 upgrading storage in historical data base 15, wherein upgrade navigation map information based on the renewal cartographic information 62 (see Figure 12) stored by area in CD-ROM 6.
As mentioned above, in the map information distribution center 3 of first embodiment of the invention, when receiving the navigation ID of coordinate data and former flag and appointment navigator 2, when former flag is opened, first area centered by the coordinate data of the original position of registration is set to range of distribution by CPU 11, when former flag is closed, the second area centered by the coordinate data of destination is set to range of distribution (S11 and S111) by CPU 11.CPU 11 reads the history-sensitive data of renewal of range of distribution in the navigation 2 of specifying with navigation ID by upgrading historical information database 15 from navigation, with the high standard in navigator 2, the current version of each block (grid) square in order to 2.5km about in the region (area subject to distribute) of distribution in the distribution road category in common and narrow street, and read difference 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 distribution road category of block in range of distribution, distinguishes data between the latest edition extracting each block in current version in navigator 2 and range of distribution, (S113).Next, CPU11 selects the distribution ID in order to identify the distinguishes data extracted, and will the allocation manager information of distributing ID be comprised, the block ID of each block of the expression range of distribution corresponding with distinguishes data, be stored into allocation manager information database 19 with the renewal version distributing road category in each block ID, then navigation device 2 sends and distributes ID and distinguishes data (S114 to S115).
Meanwhile, when upgrading navigation map information 38 based on received distinguishes data, the CPU 41 in navigator 2 sends the distribution ID that receives and the navigation ID (S12 to S16) in order to identify above-mentioned navigator 2 to map information distribution center 3.
When receiving distribution ID and navigation ID, CPU 11 in map information distribution center 3 judges that the navigation map information 38 in navigator 2 upgrades, and by reading the allocation manager information corresponding with distributing ID from allocation manager information database 19, and navigation ID specified renew into the version corresponding with the distribution road category in allocation manager information and block ID at the version upgrading the renewal historical data stored in historical data base 15, the renewal historical data of being specified by navigation ID stored in renewal 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 by reading difference Data Filename from distinguishes data management database 18, this distinguishes data filename is in order to represent the distinguishes data of the latest edition of the distribution road category of each block in range of distribution, be extracted in the distinguishes data between the current version of the navigator 2 in range of distribution in each block and the latest edition that each distributes road category, and they are sent to navigator 2, simultaneously with the high standard of the foursquare block of about 2.5km (grid), the distribution road category in common and narrow street is the version information that unit manages the navigation map information 38 stored in each navigator 2.When the map information update that the high standard in each block of the navigation map information 38 stored in the data recorder 22 of navigator 2 is distributed in road category being become latest edition, described high standard distribute road category and National Highway, rapid transit, one or two digits national road etc. relevant, map information distribution center 3 can be extracted and navigation device 2 transmission upgrades relevant minimum distinguishes data to the distribution road category in common and narrow street, and does not comprise the cartographic information relevant to high standard.Thus the amount of communication data with navigator 2 can be reduced.
When navigator 2 asks distinguishes data from map information distribution center 3, only need to send former flag, coordinate data and navigation ID from navigator 2 to map information distribution center 3 as update request data.Thus the amount of communication data sent for upgrading navigation map information 38 in navigator 2 can be reduced further.
When receiving the distribution ID be sent out together with distinguishes data and the navigation ID specifying 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 renew into each block ID of allocation manager data by upgrading the renewal historical data version of being specified by navigation ID stored in historical data base 15 and version corresponding to road category distribute, upgrade.Thus corresponding each of each block ID that accurately can manage the navigation map information 38 stored in the data recorder 22 with navigator 2 distributes the more new historical of the version information in road category, and accurately each corresponding with each block ID of the navigation map information 38 of current storage in navigator 2 of management distributes the version information in road category.
As described in detail, in the cartographic information distribution system 1 of first embodiment of the invention, when receiving the navigation ID of coordinate data and former flag and appointment navigator 2, when former flag is opened, first area centered by the coordinate data of the original position of registration is set to range of distribution by the CPU 11 of map information distribution center 3, when former flag is closed, the second area centered by the coordinate data of destination is set to range of distribution (S11 and S111) by CPU 11.CPU 11 reads the history-sensitive data of renewal of range of distribution in the navigation 2 of specifying with navigation ID by upgrading historical information database 15 from navigation, distinguishes data between the latest edition extracting each block of current version in navigator 2 and range of distribution, and extracting distinguishes data filename from distinguishes data management database 18, it is in order to represent the distinguishes data (S113) of the latest edition of block in range of distribution.Next, CPU 11 selects the distribution ID in order to identify the distinguishes data extracted, and the allocation manager information and distinguishes data that comprise distribution ID are stored into allocation manager information database 19, and then navigation device 2 sends and distributes ID and distinguishes data (S114 to S115).
Meanwhile, when upgrading navigation map information 38 based on received distinguishes data, the CPU 41 in navigator 2 sends the distribution ID that receives and the navigation ID (S12 to S16) in order to identify above-mentioned navigator 2 to map information distribution center 3.
When receiving distribution ID and navigation ID, CPU 11 in map information distribution center 3 judges that the navigation map information 38 in navigator 2 upgrades, and by reading the allocation manager information corresponding with distributing ID from allocation manager information database 19, upgrade (S116 to S118) upgrading the renewal historical data of being specified by navigation ID stored in historical data base 15.
When navigator 2 asks to upgrade cartographic information to map information distribution center 3, only need to send the former flag, coordinate data and the navigation ID that are set to open or close from navigator 2 to map information distribution center 3.Thus the navigation map information 38 upgraded in navigator 2 can be reduced to and the amount of communication data sent.
When receiving the distribution ID be sent out together with distinguishes data and the navigation ID specifying navigator 2, map information distribution center 3, by reading the allocation manager information corresponding with distributing ID from allocation manager information database 19, upgrading and upgrading the renewal historical data of being specified by navigation ID stored in historical data base 15.Thus accurately can manage the more new historical of the navigation map information 38 stored in the data recorder 22 of navigator 2, and the version information of the navigation map information 38 of accurately management current storage in navigator 2.
Because map information distribution center 3 accurately can manage the more new historical of the navigation map information 38 stored in the data recorder 22 of navigator 2, so when receiving former flag, coordinate data and navigation ID from navigator as update request data, the minimum distinguishes data for upgrading the navigation map information 38 in navigator 2 can be extracted.Thus the navigation map information 38 upgraded in navigator 2 can be reduced to further and the amount of communication data sent.
When receiving the area data representing area and regional unit requests signal from PC 5, the area of being specified by area data is set to range of distribution by the CPU 11 in map information distribution center 3, the distinguishes data management information of the latest edition of each block the region distributed by area is read from distinguishes data management database 18, based on read-out distinguishes data management data, read every a part of distinguishes data from renewal cartographic information 17, and they are stored into RAM 12 (S211 and S311).CPU 11 selects the distribution ID in order to identify the distinguishes data extracted by area, create PC allocation manager data, be stored to allocation manager information database 19 as distribution data management data, with the distinguishes data that management distributes to PC 5 by area, then send the lastest imformation (S312 to S314) of the distinguishes data of distributing ID and comprising the region distributed by area to PC 5.Meanwhile, received distribution ID and the renewal cartographic information of the distinguishes data comprising the region distributed by area are recorded to CD-ROM 6 (S212 to S213) by PC 5.
Simultaneously, CPU 41 in navigator 2 reads renewal cartographic information via reader 28 from CD-ROM 6, and when upgrading navigation map information 38, distribute ID by reading from CD-ROM 6 and it is sent to map information distribution center 3 together with the navigation ID in order to navigation by recognition equipment 2, notifying to upgrade navigation map information 38 (S31 to S35) by CD-ROM 6.When receiving distribution ID and navigation ID, the CPU 11 in map information distribution center 3 reads the PC allocation manager information corresponding with distributing ID from allocation manager information database 19.CPU 11 is by renewing the renewal historical data version stored in renewal historical data base 15 of being specified by navigation ID as upgrading (S411 to S413) with distributing version corresponding to road category to carry out with each block ID in PC allocation manager information.
CPU 41 in navigator 2 can by reading renewal cartographic information via reader 28 from CD-ROM 6, and upgrade the navigation map information 38 in the region distributed by area, the navigation map information 38 in the region distributed by area is updated to the cartographic information of latest edition.
When by upgrading the navigation map information 38 in the region distributed by area via reader 28 from CD-ROM 6 reading renewal cartographic information, the CPU 41 in navigator 2 sends from the distribution ID of CD-ROM 6 reading and the navigation ID in order to navigation by recognition equipment 2 to map information distribution center 3.Therefore, map information distribution center 3 is by renewing as with each block ID of PC allocation manager information with distribute version corresponding to road category and upgrade by the version of the renewal historical data of being specified by received navigation ID, this PC allocation manager information is corresponding with received distribution ID.For map information distribution center 3, even if when the CPU 41 in navigator 2 upgrades navigation map information 38 via CD-ROM 6, also accurately can manage the more new historical of navigation map information 38 stored in the data recorder 22 of navigator 2, and even more accurately manage the version information of navigation map information 38 of current storage in navigator 2.
Because map information distribution center 3 accurately can manage the more new historical of the navigation map information 38 stored in navigator 2, even if therefore when the CPU 41 in navigator 2 upgrades navigation map information 38 via CD-ROM 6, when receiving former flag, coordinate data and navigation ID as update request data from navigator 2, the minimum distinguishes data for upgrading the navigation map information 38 in navigator 2 also accurately can be extracted.Thus the navigation map information 38 upgraded in navigator 2 can be reduced to further and the amount of communication data sent.
The invention is not restricted to above preferred embodiment, and naturally can carry out various improvement and amendment within the scope of the invention.
