However, the probe information management device described above has a problem that, for roads with a small number of vehicles, probe information of the number of vehicles required for statistical processing cannot be obtained, and highly accurate road traffic information cannot be created.

在此，作为解决该问题的方法，例如在专利文献1中公开有如下技术：提取探测信息较少的地域(少数地域)，将提取的少数地域的信息发送给车辆侧，并且在从车辆侧接收少数地域的探测信息时对车辆侧提供规定的服务，从而促使少数地域的行驶，减少成为少数地域的地域。Here, as a method of solving this problem, for example, Patent Document 1 discloses a technique of extracting areas with less probe information (a small number of areas), transmitting the information of the extracted few areas to the vehicle side, and transmitting the information from the vehicle side When the detection information of a minority area is received, a predetermined service is provided to the vehicle side, thereby promoting driving in a minority area and reducing the number of areas becoming a minority area.

专利文献1：日本特开2009-93560号公报Patent Document 1: Japanese Patent Laid-Open No. 2009-93560

通常，在车辆侧逐次储存探测信息，在每规定的时间或每当在各路段的行驶等规定的定时，不断向探测信息管理装置发送储存的探测信息。因此，在专利文献1公开的技术中存在以下问题：即使是已经得到了统计处理所需要的辆数的探测信息的地域的探测信息，也向探测信息管理装置持续发送，对车辆侧及探测信息管理装置侧这两者来说，花费多余的通信成本。Usually, the probe information is sequentially stored on the vehicle side, and the stored probe information is continuously sent to the probe information management device at a predetermined timing such as every predetermined time or every time the vehicle travels on each link. Therefore, in the technique disclosed in Patent Document 1, there is a problem that even the probe information of an area for which the probe information of the number of vehicles required for statistical processing has been obtained is continuously sent to the probe information management device, and the vehicle side and the probe information On both sides of the management device, unnecessary communication costs are incurred.

In addition, the probe information stored in theprobe information DB 33 may be configured such that, for example, data that has elapsed for more than one day have elapsed by a predetermined period since collection by the navigation device 1 or reception by thereceiver 31, for example. Time data starts to be deleted.

判别部34基于储存在探测信息DB33中的探测信息，对于各路段(即各道路)判别是否已收集了用于制作道路交通信息的统计处理所需要的量(以下称为统计处理需要量)的探测信息(以下将该处理称为统计处理需要量到达判别处理)。这里所说的统计处理需要量表示为了制作精度较高的道路交通信息而在统计学上需要的探测信息的采样数，是可以根据要求的精度任意设定的值。Based on the probe information stored in theprobe information DB 33, the judgingunit 34 judges for each link (that is, each road) whether or not a quantity required for statistical processing for creating road traffic information (hereinafter referred to as a statistical processing required quantity) has been collected. Probe information (this processing is referred to as statistical processing requirement arrival judgment processing below). The statistical processing requirement here means the sampling number of probe information statistically required to create highly accurate road traffic information, and is a value that can be set arbitrarily according to the required accuracy.

并且，判别部34在判别为作为对象的路段的探测信息的采样数满足统计处理需要量的情况下，将表示对于该路段结束了探测信息的收集的信息收集结束标志设为有效。此外，在未判别为作为对象的路段的探测信息的采样数满足统计处理需要量的情况下，将表示对于该路段已结束探测信息的收集的信息收集结束标志设为默认的无效。即，判别部34判别统计处理需要量的探测信息已收集的路段(即已收集道路)和统计处理需要量的探测信息未收集的路段(即未收集道路)。Then, when it is judged that the number of samples of probe information of the target link satisfies the amount required for statistical processing, thedetermination unit 34 enables an information collection end flag indicating that collection of probe information has been completed for the link. Also, when it is not determined that the number of samples of probe information for a target link satisfies the amount required for statistical processing, the information collection end flag indicating that collection of probe information has ended for the link is set to invalid by default. That is, the discriminatingunit 34 discriminates links for which probe information required for statistical processing has been collected (ie, collected roads) and links for which probe information required for statistical processing has not been collected (ie, uncollected roads).

因此，判别部34将各路段的信息收集结束标志的有效无效的信息作为探测信息的收集状况的信息(以下称为收集状况信息)保存在信息收集状况保存部35中。作为一例，如图4所示，可以采用如下结构：用表将路段ID和信息收集结束标志的有效无效的信息建立关联，并将该表作为收集状况信息保存在信息收集状况保存部35中。图4是表示探测信息的收集状况的信息的一例的示意图。Therefore, thedetermination unit 34 stores the valid and invalid information of the information collection end flag of each link in the information collectionstatus storage unit 35 as information on the collection status of probe information (hereinafter referred to as collection status information). As an example, as shown in FIG. 4 , the following structure may be adopted: Link IDs and valid or invalid information of the information collection end flag are associated with a table, and the table is stored in the information collectionstatus storage unit 35 as collection status information. FIG. 4 is a schematic diagram showing an example of information on the collection status of probe information.

另外，在图4的例中，对于路段ID“A”～“E”，以及“G”～“I”的路段，信息收集结束标志为有效，对于路段ID“F”的路段，信息收集结束标志为无效。这表示，对于路段ID“A”～“E”，以及“G”～“I”的道路，已收集了制作道路交通信息所需要的量的探测信息，对于路段ID“F”的道路，尚未收集制作道路交通信息所需要的量的探测信息。In addition, in the example of FIG. 4, for the link IDs "A" to "E" and "G" to "I", the information collection end flag is valid, and for the link ID "F", the information collection is completed. flag is invalid. This means that for roads with link IDs "A" to "E" and roads "G" to "I", the amount of probe information required for making road traffic information has been collected, and for roads with link ID "F", the probe information has not yet been collected. The amount of probe information required to create road traffic information is collected.

道路交通信息制作部36对于在判别部34的判别中被判别为探测信息的采样数满足统计处理需要量的路段，通过对储存在探测信息DB33中的、从多个车辆的导航装置1提供来的探测信息进行统计处理，制作道路交通信息。作为对探测信息进行统计处理而制作道路交通信息的方法，采用使用公知的方法的结构即可。道路交通信息制作部36将制作的道路交通信息保存在道路交通信息DB37中。The road trafficinformation creation unit 36 provides the information from the navigation devices 1 of a plurality of vehicles stored in theprobe information DB 33 for the road section judged by thediscrimination unit 34 that the sampling number of the probe information satisfies the amount required for statistical processing. Statistical processing of the detected detection information to produce road traffic information. As a method of statistically processing probe information to create road traffic information, a configuration using a known method may be employed. The road trafficinformation creating unit 36 stores the created road traffic information in the roadtraffic information DB 37 .

另外，道路交通信息制作部36不限于从导航装置1接受提供的探测信息，也可以使用从都道府县警察或道路管理者等接受提供的道路交通信息来制作道路交通信息。In addition, the road trafficinformation creation unit 36 is not limited to receiving and providing probe information from the navigation device 1 , and may create road traffic information using road traffic information received and provided from the prefectural police, road managers, and the like.

发送部38将保存在道路交通信息DB37中的道路交通信息向导航装置1发送。例如，在经由信标或FM广播站发布的情况下，可以将道路交通信息以每规定的周期发送，在经由网络发布的情况下，可以在有来自导航装置1侧的请求时发送道路交通信息。此外，发送部38发送道路交通信息时，将保存在信息收集状况保存部35中的收集状况信息也向导航装置1发送。The transmittingunit 38 transmits the road traffic information stored in the roadtraffic information DB 37 to the navigation device 1 . For example, when distributing via beacons or FM radio stations, road traffic information can be transmitted every predetermined period, and when distributing via the network, road traffic information can be transmitted when there is a request from the navigation device 1 side. . In addition, when transmitting the road traffic information, thetransmission unit 38 also transmits the collection status information stored in the information collectionstatus storage unit 35 to the navigation device 1 .

在此，使用图5说明VICS中心3中的、到收集状况信息的发送为止的处理的流程。图5是表示VICS中心3中的、到收集状况信息的发送为止的处理的流程的一例的流程图。图5所示的流程为，在由接收部31接收探测信息并将新的探测信息保存到探测信息DB33中时开始，对各路段依次进行处理。Here, the flow of processing up to transmission of the collection status information in theVICS center 3 will be described using FIG. 5 . FIG. 5 is a flowchart showing an example of a flow of processing in theVICS center 3 up to transmission of collection status information. The flow shown in FIG. 5 starts when the receivingunit 31 receives the probe information and saves the new probe information in theprobe information DB 33 , and sequentially processes each link.

在步骤S1中，对于作为对象的路段，判别部34进行上述的统计处理需要量到达判别处理，转移到步骤S2。在步骤S2中，在判别为作为对象的路段的探测信息的采样数满足统计处理需要量的情况下(步骤S2：是)，转移到步骤S3。此外，未判别为作为对象的路段的探测信息的采样数满足统计处理需要量的情况下(步骤S2：否)，转移到步骤S4。In step S1, thedetermination part 34 performs the above-mentioned statistical processing required quantity arrival determination process with respect to the target link, and it transfers to step S2. In step S2, when it is judged that the sampling number of the probe information of the target link satisfies the statistical processing requirement (step S2: YES), it transfers to step S3. Also, when it is not determined that the number of samples of the probe information of the target link satisfies the amount required for statistical processing (step S2: No), the process proceeds to step S4.

在步骤S3中，判别部34将保存在信息收集状况保存部35中的收集状况信息中的、作为对象的路段的信息收集结束标志设为有效，更新收集状况信息，转移到步骤S4。In step S3, thedetermination unit 34 enables the information collection completion flag of the target link in the collection status information stored in the information collectionstatus storage unit 35, updates the collection status information, and proceeds to step S4.

在步骤S4中，对于作为对象的所有路段，已完成步骤S1～步骤S3的处理的情况下，即对象路段已全部处理的情况下(步骤S4：是)，转移到步骤S5。此外，对象路段未全部处理的情况下(步骤S4：否)，回到步骤S1，对下一路段进行统计处理需要量到达判别处理。In step S4, when the processes of steps S1 to S3 have been completed for all the target links, that is, when all the target links have been processed (step S4: Yes), the process proceeds to step S5. In addition, when not all the target links have been processed (step S4: No), return to step S1, and perform statistical processing required quantity arrival determination processing on the next link.

在步骤S5中，发送部38发送道路交通信息时，将保存在信息收集状况保存部35中的收集状况信息也向导航装置1发送，结束流程。In step S5, when thetransmission unit 38 transmits the road traffic information, the collection status information stored in the information collectionstatus storage unit 35 is also transmitted to the navigation device 1, and the flow ends.

回到图3，服务提供部39基于从导航装置1发送来的探测信息中的位置信息(在本实施方式的例中为路段ID)，参照保存在信息收集状况保存部35中的收集状况信息。然后，在收集状况信息中，与该路段ID对应的信息收集结束标志为无效的情况下，对该探测信息的发送源的导航装置1的用户提供规定的服务。Referring back to FIG. 3 , theservice provider 39 refers to the collection status information stored in the information collectionstatus storage unit 35 based on the position information (link ID in the example of this embodiment) in the probe information transmitted from the navigation device 1. . Then, when the information collection end flag corresponding to the link ID is invalid in the collection status information, a predetermined service is provided to the user of the navigation device 1 that is the transmission source of the probe information.

另外，探测信息的发送源的导航装置1的用户的确定可以采用基于附加在探测信息中的ID来进行的结构。此外，服务的提供也可以是，通过从发送部38向导航装置1发送例如各种有偿服务的优惠、能够用来转换为信用卡的积分的积分、能够在店铺中利用的优惠券的信息等。由此，通过服务的提供来给予用户利益，从而促使未收集道路的行驶。In addition, the identification of the user of the navigation device 1 as the transmission source of the probe information may be based on an ID added to the probe information. In addition, the service may be provided by transmitting from thetransmission unit 38 to the navigation device 1, for example, benefits of various paid services, points that can be converted into credit card points, information on coupons that can be used at stores, and the like. As a result, benefits are provided to the user through the provision of the service, thereby promoting travel on the uncollected road.

接着，详细说明导航装置1中的道路颜色变更处理及探测信息发送限制处理。在道路颜色变更处理中，由收发机接收到从VICS中心3发送来的收集状况信息后，控制装置26基于该收集状况信息而在显示装置19上显示基于上述地图数据的电子地图的情况下，进行能够在电子地图上区分未收集道路和已收集道路的控制。由此，控制装置26相当于显示控制部。Next, the road color change processing and probe information transmission restriction processing in the navigation device 1 will be described in detail. In the road color change process, when the collection status information transmitted from theVICS center 3 is received by the transceiver, thecontrol device 26 displays an electronic map based on the above-mentioned map data on thedisplay device 19 based on the collection status information, A control capable of distinguishing uncollected roads from collected roads on the electronic map is performed. Accordingly, thecontrol device 26 corresponds to a display control unit.

详细地说，使得与在收集状况信息中信息收集结束标志为无效的路段ID对应的路段(道路)在电子地图上的显示颜色，和与信息收集结束标志为有效的路段ID对应的路段在电子地图上的显示颜色相区分地显示。收集状况信息与图4的例相同的情况下，如图6所述，将与电子地图上的路段ID“F”对应的道路F的显示颜色和路段ID“A”～“E”、以及“G”～“I”的道路A～E、G～I的显示颜色相区分地显示。由此，导航装置1的用户能够辨别未收集道路，所以能够促使用户的车辆在未收集道路的行驶。In detail, the display color of the road section (road) corresponding to the road section ID corresponding to the invalid road section ID in the collection status information is made, and the road section corresponding to the valid road section ID with the information collection end flag is displayed on the electronic map. The display colors on the map are displayed differently. When the collection status information is the same as the example in FIG. 4, as shown in FIG. The display colors of the roads A to E and G to I of G" to "I" are displayed separately. This allows the user of the navigation device 1 to recognize the uncollected roads, so that the user's vehicle can be encouraged to travel on the uncollected roads.

另外，在本实施方式中，作为能够将未收集道路和已收集道路可区分地显示的方法，示出了使显示颜色不同的例，但是不限于此。只要是能够将未收集道路和已收集道路区分的方法，例如使未收集道路的区域闪烁显示等，也可以使用其他方法。In addition, in the present embodiment, an example of different display colors was shown as a method capable of distinguishably displaying uncollected roads and collected roads, but the present invention is not limited thereto. Other methods may be used as long as it is a method capable of distinguishing uncollected roads from collected roads, for example, displaying an area of uncollected roads by blinking.

在探测信息发送限制处理中，基于从VICS中心3发送来的收集状况信息，不向VICS中心3发送已收集了统计处理需要量的探测信息的道路的探测信息。详细地说，控制装置26进行控制，以不从收发机25发送与在收集状况信息中信息收集结束标志为有效的路段ID对应的路段(道路)的探测信息，能够只发送与信息收集结束标志为无效的路段ID对应的路段的探测信息。In the probe information transmission restriction process, based on the collection status information transmitted from theVICS center 3 , the probe information of the road for which the probe information required for statistical processing has been collected is not transmitted to theVICS center 3 . Specifically, thecontrol device 26 controls so that the probe information of the link (road) corresponding to the link ID whose information collection end flag is effective in the collection status information is not transmitted from thetransceiver 25, and only the information collection end flag can be transmitted. It is the detection information of the link corresponding to the invalid link ID.

在此，使用图7说明与导航装置1中的探测信息发送限制处理相关联的处理的流程。图7是表示与导航装置1中的探测信息发送限制处理相关联的处理的流程的一例的流程图。图7所示的流程在开始某一路段的行驶时开始。Here, the flow of processing related to the probe information transmission restriction processing in the navigation device 1 will be described using FIG. 7 . FIG. 7 is a flowchart showing an example of a flow of processing related to probe information transmission restriction processing in the navigation device 1 . The flow shown in FIG. 7 starts when the travel of a certain link starts.

首先，在步骤S11中，判定对象路段的行驶是否已结束。可以采用如下的结构：基于由位置检测器11检测到的车辆的当前位置，在当前位置移动到对象路段的下一路段时，判定为路段的行驶已结束。并且，判定为路段的行驶已结束的情况下(步骤S11：是)，转移到步骤S12。此外，在未判定为路段的行驶已结束的情况下(步骤S11：否)，重复步骤S11的流程。First, in step S11, it is determined whether or not the travel of the target link has ended. A configuration may be adopted in which, based on the current position of the vehicle detected by theposition detector 11 , when the current position moves to a link next to the target link, it is determined that the travel of the link has ended. Then, when it is determined that the travel of the link has ended (step S11: Yes), the process proceeds to step S12. In addition, when it is not determined that the travel of the link has ended (step S11: NO), the flow of step S11 is repeated.

在步骤S12中，进行已收集道路符合判别处理，转移到步骤S13。在已收集道路符合判别处理中，判定对象路段是否是与在从VICS中心3接收到的收集状况信息中信息收集结束标志为有效的路段ID对应的路段。详细地说，在收集状况信息中，根据与对象路段的路段ID对应的信息收集结束标志是否有效来判别。In step S12, the collected road conformity determination process is performed, and the process proceeds to step S13. In the collected road matching judging process, it is determined whether or not the target link is a link corresponding to a link ID whose information collection end flag is valid in the collection status information received from theVICS center 3 . Specifically, in the collection status information, it is judged based on whether or not the information collection end flag corresponding to the link ID of the target link is valid.

然后，在步骤S13中，在与对象路段的路段ID对应的信息收集结束标志为有效的情况下(步骤S13：是)，不从收发机25发送对象路段的探测信息，结束流程。此外，与对象路段的路段ID对应的信息收集结束标志不是有效的情况下(步骤S13：否)，转移到步骤S14。在步骤S14中，从收发机向VICS中心3发送对象路段的探测信息，结束流程。Then, in step S13, when the information collection end flag corresponding to the link ID of the target link is valid (step S13: Yes), the probe information of the target link is not transmitted from thetransceiver 25, and the flow ends. Moreover, when the information collection completion flag corresponding to the link ID of a target link is not valid (step S13: NO), it transfers to step S14. In step S14, the probe information of the target link is sent from the transceiver to theVICS center 3, and the flow ends.

根据以上结构，不从导航装置1向VICS中心3发送已收集了统计处理需要量的探测信息的道路的探测信息，所以不花费对导航装置1及VICS中心3的双方来说多余的通信成本。因此，能够抑制探测信息的收集中的多余的通信成本。According to the above configuration, since the navigation device 1 does not send the probe information of the road for which the probe information required for statistical processing has been collected to theVICS center 3 , unnecessary communication costs are not incurred for both the navigation device 1 and theVICS center 3 . Therefore, unnecessary communication costs in collecting probe information can be suppressed.

另外，在上述的实施方式中，示出了如下结构：基于从VICS中心3发送来的收集状况信息，在导航装置1侧判别已收集道路，不向VICS中心3发送已收集道路的探测信息，但是不限于此。例如，也可以采用如下的结构：向导航装置1发送不从VICS中心3侧发送已收集道路的探测信息的指示(以下称为发送限制指示)，在导航装置1侧，按照发送限制指示，不进行已收集道路的探测信息的发送。In addition, in the above-mentioned embodiment, the following structure was shown: Based on the collection status information transmitted from theVICS center 3, the navigation device 1 side discriminates the collected roads, and does not transmit the probe information of the collected roads to theVICS center 3, But not limited to this. For example, the following configuration may also be adopted: an instruction not to send the collected road probe information from theVICS center 3 side to the navigation device 1 (hereinafter referred to as a transmission restriction instruction), and on the navigation device 1 side, according to the transmission restriction instruction, no Transmission of the collected road probe information is performed.

这种情况下，可以采用从VICS中心3的发送部38发送用于识别已收集道路的信息(例如路段ID)和发送限制指示的结构。此外，导航装置1的控制装置26按照从VICS中心3接收的路段ID及发送限制指示，使收发机不进行已收集道路的探测信息的发送。此外，也可以通过将不发送已收集道路的探测信息的期间的信息包含在发送限制指示中，在一定期间(例如1天等)不进行已收集道路的探测信息的发送。进而，也可以是，在需要探测信息的提供的情况下，从VICS中心3向导航装置1发送取消发送限制指示的指示，从而能够提供探测信息。In this case, a configuration may be adopted in which information for identifying collected roads (for example, link ID) and a transmission restriction instruction are transmitted from thetransmission unit 38 of theVICS center 3 . In addition, thecontrol unit 26 of the navigation device 1 prevents the transceiver from transmitting the probe information of the collected roads according to the link ID and the transmission restriction instruction received from theVICS center 3 . In addition, the transmission of the collected road probe information may not be performed for a certain period of time (for example, one day) by including information on the period during which the collected road probe information is not transmitted in the transmission restriction instruction. Furthermore, when provision of probe information is required, theVICS center 3 may transmit an instruction to cancel the transmission restriction instruction to the navigation device 1 so that the probe information may be provided.

此外，在上述实施方式中，示出了在导航装置1中应用车载终端的结构，但是不限于此。只要是能够取得行驶信息和位置信息，并且能够与通信机连接的车载器，也可以在导航装置1以外的车载器中应用车载终端。In addition, in the above-mentioned embodiment, the configuration in which the vehicle-mounted terminal is applied to the navigation device 1 was shown, but it is not limited thereto. The in-vehicle terminal may be applied to in-vehicle devices other than the navigation device 1 as long as it is an in-vehicle device that can acquire travel information and position information and can be connected to a communication device.

进而，在上述的实施方式中，示出了在构成VICS中心3的服务器中应用探测信息管理装置的结构，但是不限于此。例如，也可以在构成发布VICS中心以外的道路交通信息的中心的服务器中应用探测信息管理装置。Furthermore, in the above-mentioned embodiment, the configuration in which the probe information management device is applied to the server constituting theVICS center 3 was shown, but it is not limited thereto. For example, the probe information management device may be applied to a server constituting a center distributing road traffic information other than the VICS center.

另外，本发明不限于上述的各实施方式，在权利要求所示的范围内可以进行各种变更，将不同的实施方式中分别公开的技术手段适当组合而得到的实施方式也包含在本发明的技术范围内。In addition, the present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope shown in the claims. Embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the scope of the present invention. within the technical range.
