Description

  The present invention relates to a technique for executing update of map data.

  The map data stored in the car navigation device or the mobile information processing device is required to be updated in order to keep it up-to-date. However, the map data stored in information processing devices, including car navigation devices, must be processed after the map is prepared before it can be used, and the freshness of the map is reduced by the processing period. It will be. In recent years, by preparing in advance the map data “roads that are not in service at the stage of map maintenance” (hereinafter referred to as “pre-opening route”), and changing the pre-opening route in the information processing device, Keeping freshness is done. However, the pre-opening route is not yet in use at the map development stage, and is data created from information such as drawings. Therefore, although the freshness of the map is good, the accuracy of the map is insufficient. For example, left and right guidance may be reversed in a car navigation device, which may be disadvantageous for the user.

  For example, Patent Document 1 discloses a method of maintaining freshness by preparing a unique identifier for each route before opening and updating the availability information in the information processing apparatus. However, if there is a problem with the route before opening, it is not possible to distinguish between the data including the problem before the correction and the appropriate data after the correction, and the appropriate data after the correction cannot be used. There is a case.

JP 2012-37799 A

  Accordingly, an object of the present invention is to provide an information processing apparatus and system for updating map data with higher freshness and accuracy even when there is some problem with the route before opening.

  The information processing apparatus according to the present invention includes a pre-opening information storage unit that stores pre-opening information that includes information related to a scheduled service line, and map data that stores information related to map data including a serviced and planned service line A control unit that controls a storage unit, a map data use determination unit that determines whether map data corresponding to the stored pre-opening information can be used, a pre-opening information storage unit, a map data storage unit, and a map data use determination unit The map data availability determination unit is related to the information on the unused data version stored in the pre-opening information storage unit as the pre-opening information and the data version of the map data stored in the map data storage unit It is characterized by determining the availability of map data by comparing information.

  According to the configuration of the present invention, map data with higher freshness and accuracy can be provided to the user.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, FIG. 1 is a functional block diagram showing the entire map data update system, which is composed of a center 4 and an information processing apparatus 1 connected to the center 4. Specifically, the information processing apparatus 1 includes a transmission / reception unit 2 that communicates with the center 4, a pre-opening information storage unit 11 that stores pre-opening information updated through communication with the center 4, and a map data storage that stores map data. Unit 16, map data switching unit 15 that rewrites (switches) the map data based on pre-opening information, date information storage unit 12 that stores the current date, date information, and availability of map data based on pre-opening information. A map data availability determination unit 14 for determining, an input unit 13 for receiving information input from the user, an output unit 3 for outputting map data and the like to the user, and a control unit 17 for controlling these functional units. The

  Here, the transmission / reception unit 2 is not inside the information processing apparatus 1 but can be replaced by an external apparatus. The map data switching unit 15 is not necessarily separated from the control unit 17, and the map data may be rewritten by the control unit 17. Further, the input unit 13 and the output unit 3 can be shared by using a touch panel or the like. In this case, the input unit 13 and the output unit 3 are expressed as an input / output unit. Further, the date information storage unit 12 may store the date in advance, or may be configured to acquire and store date information as needed using a GPS or the like.

  Next, FIG. 2 shows an example of a table of the pre-opening information storage unit 11 stored as pre-opening information. Here, the pre-opening route ID is a road that is scheduled to be in service, but it is not in use at the map development stage, and the route data created by guessing from the drawings is referred to as the pre-opening route. This is a unique ID assigned to each route of the previous route. Therefore, it is possible to designate whether or not the information processing apparatus 1 can use each route ID before opening. The closed route ID is a unique ID assigned to a route ID when there is a route that is closed simultaneously with the start of operation with respect to the pre-opening route ID. Therefore, nothing is stored when there is no route to be closed. The closed route ID is not necessarily expressed by a unique ID, and may be the same as the route ID before opening. However, in that case, it is necessary to prepare an identifier for identifying the route before opening and the closed route as a format. Furthermore, the scheduled service date is the scheduled date on which the pre-opening route ID is serviced. Next, the date confirmation flag is a flag for identifying whether the scheduled service date is “unconfirmed” or “confirmed”. When the date confirmation flag is “unconfirmed”, whether or not the relevant pre-opening route can be used is determined by the user after the scheduled service date has passed. If the date confirmation flag is “confirmed”, the map data availability determination unit 14 enables the corresponding pre-opening route after the scheduled service date has passed.

  The route confirmation flag is a flag for identifying whether the route is “unconfirmed” or “confirmed” in actual traveling as data of the route before opening. When the route confirmation flag is “unconfirmed”, the data of the route before opening still has many uncertain elements as information. In this way, the pre-opening information storage unit 11 stores information indicating whether or not the actual travel has been confirmed for the scheduled route, and the control unit 17 indicates that the route confirmation flag is “unconfirmed” and the actual travel is performed. It is possible to provide more accurate map information by restricting the use of map data if the confirmation is not confirmed, and not using the restriction if the route confirmation flag is "Confirmed" become.

  Next, Unused DATA VERSION (synonymous with “unused data version”) stores DATA VERSION (synonymous with “data version”) that has a problem with the stored pre-opening route and should not be used as map data. . Since there may be a plurality of unused DATA VERSIONs, a plurality of unused DATA VERSIONs can be stored. As for the availability flag, the map data availability determination unit 14 rewrites 0 = “unusable” or 1 = “usable” with respect to the route ID before opening. When the availability flag is 0 = “unusable”, the control unit 17 performs control so that the corresponding pre-opening route cannot be used. When 1 = “usable”, the control unit 17 Control to use the route before opening. In this embodiment, the availability flag is rewritten by the map data availability determination unit 14, but it may be rewritten by the control unit 17. The other pre-opening information can be updated by the control unit 17 via the transmission / reception unit 2.

  Here, handling of unused DATA VERSION will be described. First, DATA VERSION is a map identifier given when creating map data, and a different identifier is given each time map data is created. When updating map data, the handling of DATA VERSION differs depending on the update method. For example, if the map data is completely replaced, DATA VERSION is always replaced with the latest one. In another updating method, it is possible to change only one road data. In this embodiment, any update unit can be changed to unusable if there is a problem with the map data. For example, a specific example in which one road data has a problem and one of the road data is updated by updating the map data will be described with reference to FIG. Assume that there is a problem with the link ID 1003 (VER: A) in the route corresponding to the pre-opening route ID 10000 (301). In this case, as the pre-opening information corresponding to the pre-opening route ID 10000, the unused DATA VERSION is set at the center as “A”, and the content is reflected in the pre-opening information storage unit 11 by the update process (302). Then, all the links in the pre-opening route ID 10000 are DATA VERSION “A” and match the set unused DATA VERSION, and therefore the pre-opening route ID 10000 cannot be used. That is, the map data availability determination unit 14 determines that the map data cannot be used.

  Next, in 303, since only the link ID 1003 (VER: A) is wrong in the map data 301, a case where the link data is updated to the link ID 1005 (VER: B) by applying the update data is shown. In this case, since some of the links (link ID 1005 (VER: B)) in the pre-opening route ID 10000 do not match the set non-use data DATA VERSION, it is determined that the pre-opening route ID 10000 is usable ( 304). That is, the map data availability determination unit 14 determines that the map data can be used. Furthermore, if there is a problem with the map ID 1005 as map data, by adding "B" to the unused DATA VERSION as shown by 305, the DATA VERSION of all links in the pre-opening route ID 10000 is Since this applies to the non-use DATA VERSION set additionally, the pre-opening route ID 10000 is determined to be unusable.

  Thus, a pre-opening information storage unit that stores pre-opening information that includes information related to the scheduled service line, a map data storage unit that stores information related to map data including the serviced and planned service lines, and storage A map data availability determination unit that determines the availability of map data corresponding to the pre-opening information, and a control unit that controls the pre-opening information storage unit, the map data storage unit, and the map data availability determination unit. The map data availability determination unit compares the information on the non-use data version stored as the pre-opening information in the pre-opening information storage unit with the information on the data version of the map data stored in the map data storage unit. By adopting a configuration for determining whether or not map data can be used, it is possible to proceed with more accurate map data update. Specifically, when the information about the non-use data version and the information about the data version of the map data stored in the map data storage unit are all matched, the map data is determined not to be usable. preferable.

  Next, FIG. 4 shows an example of a table related to map data stored in the map data storage unit 16, but there are various storage methods depending on the format, and this configuration is not necessarily required. For example, the map data includes road data, route data, background data, name data, and search data. Here, background data refers to icons and the like displayed on the screen, name data refers to road names, and search data refers to information related to search processing such as service areas. Each of the road data, route data, background data, name data, and search data includes a route ID before opening, a DATA VERSION, a route confirmation flag, and an availability flag. In particular, the availability flag is not necessarily stored in the map data storage unit 16 and may be stored only in the pre-opening information storage unit 11. In this case, in the information processing apparatus 1, whether to use the pre-opening route of the corresponding map data is determined by using the pre-opening route ID stored in the map data storage unit 16 as a key in the pre-opening information storage unit 11. It is necessary to check the stored use flag.

  Here, an identifier corresponding to each pre-opening information stored in the pre-opening information storage unit 11 is stored as the pre-opening route ID, and a data version when map data is created is stored as the DATA VERSION. The Further, as the route confirmation flag, a flag corresponding to each pre-opening route ID stored in the pre-opening information storage unit 11 is stored. This route confirmation flag does not necessarily need to be stored in the map data storage unit 16, and the route confirmation flag of each pre-opening information may be referred to using the pre-opening route ID as a key. Further, as the availability flag, a flag corresponding to the pre-opening route ID stored in the pre-opening information storage unit 11 is stored, but it is not necessarily stored in the map data storage unit 16, and the pre-opening route You may refer to the availability flag of each pre-opening information using the ID as a key.

  Next, processing in the map data switching unit 15 will be described. As a switching method, when the pre-opening information is updated, the date information stored in the updated pre-opening information and the scheduled service date are compared and changed, and the date information storage unit 12 The method b for comparing and changing the current date stored in the current date and the scheduled service date stored in the pre-opening information storage unit 11 and the method c forcibly changing by an input operation from the user are considered. However, it is not limited to any of these.

First, the map data switching process (method a) executed when the pre-opening information is updated will be described with reference to FIG. First, the pre-opening information stored in the pre-opening information storage unit 11 is updated by the user or automatically. Specifically, based on the pre-opening information communication request from the input unit 13 by the user (501), the control unit 17 notifies the center 4 of the pre-opening information request (502). Further, the control unit 17 that has received the pre-opening information from the center 4 (503) updates the stored information in the pre-opening information storage unit 11 (504). Here, each information of the pre-opening information is updated. Thereafter, based on the unused DATA VERSION stored in the pre-opening information storage unit 11, it is determined whether or not the DATA VERSION of the map data can be used (505). If it is determined that the data can be used, the date information Current date information is acquired in the storage unit 12 (506), the map data availability determination unit 14 determines whether the route before opening is available (507), and the map data stored according to the result is stored. This is executed by switching the availability flag (510). After 506, based on the determination result, if the scheduled service date is “unconfirmed”, the user can select whether to open the pre-opening route through the input unit 13 or the output unit 3 (or input / output unit). (508), and whether or not the map data availability flag can be switched is determined based on the selection result (509, 510).
It is not always necessary to request an update from the input unit 13, and the update process may be started when the control unit 17 periodically requests the center 4 to update via the transmission / reception unit 2. 4 may be distributed to the control unit 17 via the transmission / reception unit 2 in a push type.

  Thus, a map data update system having a center that distributes information related to map data and an information processing device that communicates with the center, wherein the information processing device transmits and receives information related to the map data from the center, A pre-opening information storage unit that stores pre-opening information including information related to scheduled routes, a control unit that updates stored pre-opening information based on information related to map data received from the center, and Based on the map data storage unit that stores information related to the map data including the planned route, and the stored pre-opening information and the stored map data information, the availability of the map data corresponding to the pre-opening information is determined. A map data availability determination unit for determining, and the map data availability determination unit is stored as pre-opening information in the pre-opening information storage unit By adopting a configuration that determines the availability of map data by comparing the information on the use data version with the information on the data version of the map data stored in the map data storage unit, it is based on the new pre-opening information. Therefore, it is possible to determine whether or not the service can be used, and it is possible to provide map data with higher accuracy. Further, the information processing apparatus has an input / output unit capable of inputting / outputting information to / from the user, and the control unit receives the pre-opening information update request from the input / output unit or the center. By adopting a configuration to update the storage unit, not only based on the pre-opening information update request from the control unit, but also when a pre-opening information update request is sent from the user periodically, or periodically from the center In addition, it is possible to cope with the case where the pre-opening information is distributed, and it is possible to determine whether or not the service can be used based on the new pre-opening information, and it is possible to provide map data with higher accuracy.

  Next, a method (method b) of comparing and changing the current date stored in the date information storage unit 12 and the scheduled service date stored in the pre-opening information storage unit 11 will be described. For example, a mechanism for acquiring the date at which the information processing apparatus 1 is activated or periodically is provided. Then, similarly to the method a, based on the non-use DATA VERSION stored in the pre-opening information storage unit 11, it is determined whether or not the DATA VERSION of the map data can be used, and it is determined that the map data can be used. Based on the acquired current date information, the map data availability determination unit 14 determines the route to be used and the route to be disabled, and rewrites the availability flag in the map data storage unit 16. As described above, depending on the performance of the information processing apparatus 1, it is not always necessary to store the availability flag in the map data storage unit 16. If the map data storage unit 16 does not have the availability flag, this rewriting process is performed. It becomes unnecessary.

  In addition, when the user selects whether or not the route before opening is usable by the input unit 13 (method c), the map data availability flag is rewritten according to the availability as the selection result. However, as in the methods a and b, it is determined whether or not the DATA VERSION of the map data can be used based on the non-used DATA VERSION stored in the pre-opening information storage unit 11, and it is determined that it can be used. If the current date information is acquired by the date information storage unit 12, the map data availability determination unit 14 determines the availability of the route before opening, and uses the map data stored according to the result. It is executed by switching the availability flag. Further, based on the determination result, when the scheduled service date is “indeterminate”, the user input unit 13 or the display unit 3 is used to determine whether to open the pre-opening route, and the map is based on the selection result. It is determined whether or not the data availability flag can be switched. Furthermore, as described above, depending on the performance of the information processing apparatus 1, it is not always necessary to store the availability flag in the map data storage unit 16, so when the availability flag is not stored in the map data storage unit 16, This rewriting process is unnecessary. Here, in the case where the input unit 13 also serves as the output unit 3, there is no problem even if the output unit 3 selects the availability.

  Next, the determination processing flow of the map data availability determination unit 14 will be described with reference to FIG. This determination processing flow occurs, for example, at 504 in FIG. First, the pre-opening route ID is acquired from the pre-opening information storage unit 11 (601). It is determined from the acquired pre-opening route ID whether or not map data DATA VERSION can be used (602). If it is determined that the DATA VERSION of the map data is unusable, the usability flag of the pre-opening information is changed to 0 = “unusable” (607). If it is determined that it can be used, it is determined whether the current date exceeds the scheduled service date of the pre-opening information (603). If the current date does not exceed the scheduled service date of the pre-opening information, the availability flag of the pre-opening information is changed to 0 = “unusable” (607). If the current date exceeds the scheduled service date of the pre-opening information, it is determined whether or not the date fixed flag of the pre-opening information is “incomplete” (604). If it is not “indeterminate” but “determined”, it is determined that the map data can be used, and the availability flag is set to 1 = “usable” (606). If the date confirmation flag is “unconfirmed”, the user is allowed to select whether or not the corresponding pre-opening route can be used as map data (605). As a result of the selection, if it is disabled, the availability flag of the pre-opening information is changed to 0 = “unusable” (607). To enable use, the use flag is set to 1 = “use” (606). When the flow ends in this way, the next pre-opening route ID is acquired and the same processing is performed. If the same processing is performed for all the pre-opening route IDs, the determination processing flow is completed.

  As described above, the information processing apparatus includes a date information storage unit that stores date information, and relates to the scheduled service date stored in the pre-opening information storage unit as the date information stored in the date information storage unit and the pre-opening information. By adopting a configuration that compares the information and determines the availability of map data, it is possible to automatically determine availability according to the scheduled service date, and to provide map data with higher freshness Can do. Further, the information processing apparatus has an input / output unit capable of inputting / outputting information to / from the user, and the pre-opening information storage unit determines whether the information on the scheduled service date and the scheduled service date are unconfirmed. When the scheduled service date is uncertain, the control unit adopts a configuration that allows the user to select whether or not to use the route to be supplied via the input / output unit. Convenience can be improved by allowing the user to make a service determination according to the actual situation while ensuring.

  Next, using DATA VERSION of the map data 602 in FIG. 6 will be described with reference to FIG. First, the unused DATA VERSION of the pre-opening information corresponding to the pre-opening route ID acquired in 601 is acquired (701). Next, the DATA VERSION of the road data of the map data is acquired using the pre-opening route ID as a key (702). In addition to road data, DATA VERSION of route data (703), background data (704), name data (705), and search data (706) is also acquired. If the acquired DATA VERSION matches all the unused DATA VERSION acquired in 701, the route ID before opening cannot be used for the map data, so the DATA VERSION of the map data cannot be used. It is determined that there is (708). If the acquired DATA VERSION does not match all of the unused DATA VERSION acquired in 701, the route ID before opening can be used for the map data, so it is determined that the DATA VERSION of the map data can be used. (709). It should be noted that the contents (road data, route data, background data, name data, search data) in 702 to 706 are not necessarily required. For example, only road data may be used to determine whether or not the data can be used.

  Next, an example of the map data switching process will be described with reference to FIG. The map data switching process in FIG. 8 occurs at 510 in FIG. First, the pre-opening route ID stored in the pre-opening information storage unit 11 is acquired (801). Next, it is determined whether or not the availability flag of the pre-opening information has been changed (802). If the change has been made, it is determined whether the availability flag before the change is “0” or “1” (803). . That is, some processes differ depending on whether the usability flag before the change is 0 = “unusable” or 1 = “usable”.

  First, a case where 1 = “available” before the change will be described. In this case, a problem occurs on the route before opening that was usable, and this occurs when the use is changed to unusable. First, all map data corresponding to the route ID before opening is acquired (804). The availability flag of the acquired map data is set to 0 = “unusable” (805). Next, it is determined whether the closed route ID exists in the pre-opening information (806). Here, the closed route means a route that had to be closed when the pre-opening route was in service, so there was a problem with the route that had been started and when it was changed to unusable, the closed route Must be changed from disabled to enabled. That is, if there is a closed route ID, all map data corresponding to the closed route ID is acquired (807). Then, the availability flag of the acquired map data is set to 1 = “usable” (808).

  Next, the case where 0 = “unusable” before the change in 803 will be described. The flow from 809 to 813 is a flow in which the change of the availability flag is reversed with respect to the flow from 804 to 808. That is, all the map data of the route ID before opening is acquired (809), the availability flag of the map data is changed to 1 = “available” (810), and it is determined whether the closed route ID of the information before opening exists. (811). If there is a closed route, all map data corresponding to the closed route ID is acquired (812), and the availability flag of the acquired map data is changed to 0 = “unusable” (813). When the flow ends, the next pre-opening route ID is acquired and the same processing is performed. When the same processing is performed for all pre-opening route IDs, the processing is completed.
