Description

  The present invention relates to a probe information management system, an in-vehicle terminal, and a probe information management apparatus.

  2. Description of the Related Art Conventionally, a probe information management apparatus that collects probe information including vehicle position information and travel information transmitted from a vehicle side, performs statistical processing, and creates road traffic information such as traffic jam information is known. However, the above-described probe information management device has a problem in that it cannot obtain probe information for the number of vehicles necessary for statistical processing for roads with a small number of vehicles traveling, and cannot create highly accurate road traffic information. .

  Therefore, as means for solving this problem, for example, in Patent Document 1, an area with a small amount of probe information (minority area) is extracted, and information on the extracted minority area is transmitted to the vehicle side. A technique is disclosed in which a predetermined service is provided to the vehicle side when the probe information is received, thereby promoting traveling in a minority region and reducing the number of minority regions.

JP 2009-93560 A

  In general, probe information is sequentially accumulated on the vehicle side, and the accumulated probe information is always transmitted to the probe information management device at a predetermined timing such as every predetermined time or every travel of each link. . Therefore, in the technique disclosed in Patent Document 1, even if the probe information of the area for which the number of pieces of probe information necessary for statistical processing has already been obtained, the probe information management apparatus continues to transmit the probe information to the vehicle side and the probe information. There is a problem in that useless communication costs are incurred for both management devices.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a probe information management system, an in-vehicle terminal, and probe information management that can suppress useless communication costs in collecting probe information. To provide an apparatus.

Provided with a discriminator that discriminates between collected roads and non-collected roads that have not been collected with the amount of probe information required to create road traffic information. Probe information management apparatus for probe information on collected roads based on information on collected roads and non-collected roads transmitted from the probe information management apparatus. Will not be sent to.

  Further, in the probe information management system according to claim 2, the road on which the probe information management apparatus collects the amount of probe information necessary to create road traffic information based on the probe information collected from the in-vehicle terminal. A collecting means for discriminating between the collected road and a non-collected road that is a road from which the amount of probe information necessary for creating road traffic information has not been collected, Send at least a non-collected road information of non-collected road information to the in-vehicle terminal, and a transmission restriction instruction that instructs the in-vehicle terminal not to transmit probe information about the collected road The probe information tube of the probe information on the collected road is transmitted based on the transmission restriction instruction transmitted from the probe information management device. It will be to not transmit to the device.

  According to the configuration of claims 1 and 2, since the probe information about the road where the amount of probe information necessary for creating road traffic information is collected is not transmitted from the in-vehicle terminal to the probe information management device, There is no unnecessary communication cost for both the in-vehicle terminal and the probe information management device. Accordingly, it is possible to suppress useless communication costs in collecting probe information.

  According to the configuration of the third aspect, since the non-collected roads are displayed on the electronic map on the display of the in-vehicle terminal so as to be distinguishable from the collected roads, the user can recognize the non-collected roads.

Collected roads received from the probe information management device that received information about collected roads that are roads and non-collected roads that have not collected the amount of probe information necessary to create road traffic information Based on the information on the road and the non-collected road, the probe information on the collected road is not transmitted to the probe information management device.

  According to this, since the in-vehicle terminal does not transmit the probe information about the road where the amount of probe information necessary for creating the road traffic information is collected to the probe information management device, it is wasteful in collecting the probe information. It becomes possible to hold down the communication cost.

  The probe information management apparatus according to claim 6, wherein collected roads and road traffic are roads on which probe information of an amount necessary for creating road traffic information is collected based on the probe information collected from the in-vehicle terminal. It is provided with a discriminating means for discriminating non-collected roads that are roads for which the amount of probe information necessary for creating information has not been collected. Of the collected road and non-collected road information discriminated by the discriminating means At least the information on the non-collected road is transmitted to the in-vehicle terminal, and the transmission restriction instruction that is an instruction to prevent the in-vehicle terminal from transmitting the probe information about the collected road is transmitted.

  According to this, the probe information management device prevents the probe information about the road from which the amount of probe information necessary for creating the road traffic information is collected from being transmitted from the in-vehicle terminal. It is possible to reduce unnecessary communication costs.

  The display device 19 displays a map or the like for guiding driving of the vehicle, and is capable of full color display, for example, and may be configured using a liquid crystal display, an organic EL display, a plasma display, or the like. it can. The display device 19 corresponds to a display device in claims. The voice output device 20 includes a speaker or the like, and outputs a guidance voice at the time of route guidance based on an instruction from the control device 26. The voice recognition unit 21 recognizes voice input from a microphone (not shown), and outputs a control command corresponding to the recognized voice to the control device 26. The control device 26 executes processing according to this control command.

  For example, a touch switch or a mechanical switch integrated with the display device 19 is used as the operation switch group 22, and operation instructions for various functions are given to the control device 26 by a switch operation. The remote controller 23 is provided with a plurality of operation switches (not shown). By inputting various command signals to the control device 26 via the remote control sensor 24 by the switch operation, the control device 26 has the same function as the operation switch group 22. Can be executed.

  The transceiver 25 receives information such as road traffic information distributed from the VICS center via beacons laid on a network or road, or FM broadcast stations in various places. Further, the transmitter / receiver 25 transmits the probe information collected by the probe information collecting function to the outside (the VICS center 3 in the present embodiment) according to the instruction of the control device 26. The transmission of probe information from the transceiver 25 to the VICS center 3 may be performed via an in-vehicle communication module used for telematics communication such as DCM (data communication module), for example, Bluetooth (registered trademark) For example, a configuration may be adopted in which the mobile phone is connected via a mobile phone.

The collected probe information is stored in a memory such as the external memory 18 in association with traveling information, information on a traveling position where the traveling information is obtained, and time information such as the date and time when the traveling information is obtained. The time information may be configured to use time information obtained from a GPS satellite via a timer circuit (not shown) or the GPS receiver 15.

  For example, the probe information may be handled in units of road sections. In this case, for each of a plurality of road sections corresponding to the past travel route of the host vehicle, position information that can identify each road section (for example, information on the longitude and latitude of the start point and end point of the road section), The travel information of the road section and the information on the date and time of traveling on the road section are linked and accumulated. In addition, it is good also as a structure which makes the above-mentioned link the unit of a road area. In this case, it is good also as a structure which uses link ID as positional information.

  In the probe information transmission processing, identification information (for example, the ID of the vehicle or the navigation device 1) for identifying the vehicle on which the navigation device 1 is mounted is added to the probe information collected and accumulated in the probe information collection processing. Then, the data is transmitted from the transceiver 25 to the VICS center 3 at a predetermined timing. The predetermined timing mentioned here may be, for example, every fixed time such as every 5 minutes, or every traveling of each link, every fixed traveling distance, or the like. In the present embodiment, the following description will be given by taking as an example a case where probe information is transmitted for each travel of each link. The road color change process and the probe information transmission restriction process will be described in detail later.

  Returning to FIG. 1, the VICS center 3 is a base station placed on the ground, and includes a server. The server constituting the VICS center 3 corresponds to the probe information management device in the claims. The VICS center 3 then sends information on the degree of traffic congestion, information on the time required for the section indicating the time required for traffic (that is, information on the link travel time), and information on traffic obstacles such as traffic closure due to accidents or construction. Road traffic information such as traffic restriction information such as traffic closures and temporary restrictions is transmitted (distributed) via networks, beacons laid on the road, and FM broadcast stations in various places. The VICS center 3 collects the probe information transmitted from the navigation devices 1 of a plurality of vehicles, and creates road traffic information by statistically processing the collected probe information.

  The VICS center 3 may be composed of one server or may be composed of a plurality of servers. For example, a configuration in which a server that creates and distributes road traffic information and a server that collects probe information may be provided.

  Here, a schematic configuration of the VICS center 3 will be described with reference to FIG. FIG. 3 is a block diagram showing a schematic configuration of the VICS center 3. As shown in FIG. 3, the VICS center 3 includes a receiving unit 31, a storage control unit 32, a probe information database (DB) 33, a determination unit 34, an information collection status storage unit 35, a road traffic information creation unit 36, a road traffic information. A database (DB) 37, a transmission unit 38, and a service providing unit 39 are provided.

  The receiving unit 31 receives probe information transmitted from the navigation device 1. The storage control unit 32 stores the probe information received by the receiving unit 31 in the probe information DB 33. Each time new probe information is received by the receiving unit 31, the storage control unit 32 stores the received probe information in the probe information DB 33, thereby accumulating the probe information in the probe information DB 33. Note that the probe information stored in the probe information DB 33 is erased from those that have passed a predetermined time, such as those that have passed for more than a day since collection at the navigation device 1 or reception at the receiving unit 31. What is necessary is just to make it a composition.

  Based on the probe information accumulated in the probe information DB 33, the determination unit 34 requires an amount necessary for statistical processing for creating road traffic information for each link (that is, each road) (hereinafter, statistical processing is required). (Amount) of probe information is collected (hereinafter referred to as a statistical processing required amount arrival determination process). The amount of statistical processing required here refers to the number of samples of probe information that are statistically required to create highly accurate road traffic information, and can be set arbitrarily according to the required accuracy. Possible value.

  If the determination unit 34 determines that the number of samples of the probe information for the target link satisfies the statistical processing requirement amount, the determination unit 34 sets an information collection completion flag indicating that the collection of the probe information has been completed for the link. turn on. Also, if it is not determined that the number of samples of probe information for the target link has met the statistical processing requirement, the information collection completion flag indicating that probe information has been collected for that link is turned off by default. Leave as it is. That is, the determination unit 34 determines a link for which the statistical processing required amount of probe information has been collected (that is, a collected road) and a link for which the statistical processing required amount of probe information has not been collected (that is, a non-collected road). To do. Therefore, the determination unit 34 corresponds to a determination unit in claims.

  The determination unit 34 stores information collection completion flag on / off information for each link in the information collection status storage unit 35 as probe status collection status information (hereinafter, collection status information). As an example, as shown in FIG. 4, a table in which link IDs and information collection completion flag on / off information are linked may be stored in the information collection status storage unit 35 as collection status information. FIG. 4 is a schematic diagram illustrating an example of probe information collection status information.

  In the example of FIG. 4, the information collection completion flag is turned on for the links with the link IDs “A” to “E” and “G” to “I”, and the information is collected for the link with the link ID “F”. The completion flag is off. For the roads with link IDs “A” to “E” and “G” to “I”, the probe information has been collected in an amount necessary for creating road traffic information, and the link ID “F”. This indicates that the probe information has not been collected in the amount necessary to create the road traffic information.

  The road traffic information creation unit 36 determines from the navigation devices 1 of a plurality of vehicles stored in the probe information DB 33 about the links for which the number of samples of probe information satisfies the statistical processing necessary amount in the determination by the determination unit 34. Road traffic information is created by statistically processing the provided probe information. A known method may be used as a method for statistically processing the probe information to create road traffic information. The road traffic information creation unit 36 stores the created road traffic information in the road traffic information DB 37.

  The road traffic information creating unit 36 creates road traffic information using not only the probe information provided from the navigation apparatus 1 but also the road traffic information provided from the prefectural police or the road manager. It is good.

  The transmission unit 38 transmits the road traffic information stored in the road traffic information DB 37 to the navigation device 1. For example, in the case of delivery via a beacon or FM broadcast station, the road traffic information may be transmitted at a predetermined cycle. In the case of delivery via a network, there is a request from the navigation device 1 side. In such a case, road traffic information may be transmitted. The transmission unit 38 also transmits the collection status information stored in the information collection status storage unit 35 to the navigation device 1 when transmitting road traffic information.

  Here, the flow of processing up to the transmission of the collection status information in the VICS center 3 will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of a processing flow up to transmission of collection status information in the VICS center 3. The flow shown in FIG. 5 is started when probe information is received by the receiving unit 31 and new probe information is stored in the probe information DB 33, and processing is performed in order for each link.

  In step S1, the determination unit 34 performs the above-described statistical process necessary amount arrival determination process for the target link, and the process proceeds to step S2. If it is determined in step S2 that the number of samples of probe information for the target link satisfies the statistical processing requirement (YES in step S2), the process proceeds to step S3. If it is not determined that the number of samples of probe information for the target link satisfies the statistical processing requirement (NO in step S2), the process proceeds to step S4.

  In step S3, of the collection status information stored in the information collection status storage unit 35, the determination unit 34 turns on the information collection completion flag for the target link to update the collection status information. Move.

  In step S4, if the processing of steps S1 to S3 is completed for all the links to be processed, that is, if the processing of all the links is completed (YES in step S4), the process proceeds to step S5. If all the target links have not been processed (NO in step S4), the process returns to step S1 and the statistical process necessary amount arrival determination process is performed for the next link.

  In step S5, when the transmission unit 38 transmits road traffic information, the collection status information stored in the information collection status storage unit 35 is also transmitted to the navigation device 1, and the flow ends.

  Returning to FIG. 3, the service providing unit 39 is stored in the information collection status storage unit 35 based on the position information (link ID in the example of the present embodiment) in the probe information transmitted from the navigation device 1. Refer to the collected status information. When the information collection completion flag corresponding to the link ID is off 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. Therefore, the service providing unit 39 corresponds to the service providing unit in the claims.

  In addition, what is necessary is just to set it as the structure which identifies the user of the navigation apparatus 1 of the transmission origin of probe information based on ID added to probe information. For providing the service, for example, points that can be used for discounts on various paid services, conversion to credit card points, coupon information that can be used at the store, and the like are transmitted from the transmission unit 38 to the navigation device 1. It is sufficient to adopt the configuration performed in According to this, it is possible to prompt the user to travel on the non-collected road by providing a benefit to the user by providing the service.

  Subsequently, the road color change process and the probe information transmission restriction process in the navigation device 1 will be described in detail. In the road color change process, when the collection status information transmitted from the VICS center 3 is received by the transceiver 25, the control device 26 displays an electronic map based on the map data on the display device 19 based on the collection status information. In the case of display, control is performed so that non-collected roads are displayed on the electronic map so as to be distinguishable from collected roads. Therefore, the control device 26 corresponds to the display control means in the claims.

  Specifically, the display color on the electronic map of the link (road) corresponding to the link ID whose information collection completion flag is off in the collection status information corresponds to the link ID whose information collection completion flag is on The link to be displayed is displayed differently from the display color on the electronic map. When the collection status information is the same as that shown in the example of FIG. 4, the display color of the road F corresponding to the link ID “F” on the electronic map is changed to the link ID “A” as shown in FIG. -"E" and "G"-"I" are displayed differently from the display colors of the roads A-E, G-I. According to this, since it becomes possible for the user of the navigation apparatus 1 to recognize the non-collected road, it is possible to prompt the user to travel on the non-collected road of the vehicle.

  In the present embodiment, as an example of displaying a non-collected road so as to be distinguishable from a collected road, an example in which the display color is changed is shown, but the present invention is not necessarily limited thereto. As long as it is a method that can distinguish a non-collected road from a collected road, another method may be used, for example, a non-collected road area is blinked.

  In the probe information transmission restriction process, based on the collection status information transmitted from the VICS center 3, the probe information about the road where the statistical information necessary amount of probe information is collected is not transmitted to the VICS center 3. Specifically, the control device 26 controls the probe device 26 so as not to transmit the probe information about the link (road) corresponding to the link ID whose information collection completion flag is turned on in the collection status information, and the information collection is completed. Only the probe information about the link corresponding to the link ID whose flag is off can be transmitted.

  Here, the flow of processing related to the probe information transmission restriction processing in the navigation device 1 will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of a process flow related to the probe information transmission restriction process in the navigation device 1. The flow shown in FIG. 7 is assumed to start when traveling on a certain link is started.

  First, in step S11, it is determined whether traveling of the target link is completed. Based on the current position of the vehicle detected by the position detector 11, it may be configured to determine that the travel of the link has been completed when the current position has moved to the next link of the target link. And when it determines with the driving | running | working of the link having been completed (it is YES at step S11), it moves to step S12. If it is not determined that the travel of the link has been completed (NO in step S11), the flow in step S11 is repeated.

  In step S12, a collected road corresponding determination process is performed, and the process proceeds to step S13. In the collected road corresponding determination process, it is determined whether or not the target link is a link corresponding to a link ID whose information collection completion flag is on in the collection status information received from the VICS center 3. Specifically, it is determined according to whether or not the information collection completion flag corresponding to the link ID of the target link is on in the collection status information.

  In step S13, if the information collection completion flag corresponding to the link ID of the target link is on (YES in step S13), the probe information of the target link is not transmitted from the transceiver 25, and the flow ends. To do. If the information collection completion flag corresponding to the link ID of the target link is not on (NO in step S13), the process proceeds to step S14. In step S14, the probe information of the target link is transmitted from the transceiver 25 to the VICS center 3, and the flow ends.

  According to the above configuration, probe information about a road on which a necessary amount of statistical processing probe information has been collected is not transmitted from the navigation device 1 to the VICS center 3, so that both the navigation device 1 and the VICS center 3 are useless. High communication costs. Accordingly, it is possible to suppress useless communication costs in collecting probe information.

  In the above-described embodiment, the navigation apparatus 1 determines the collected road based on the collection status information transmitted from the VICS center 3, and does not transmit the probe information about the collected road to the VICS center 3. Although the structure to do is shown, it is not necessarily limited to this. For example, an instruction not to transmit probe information on a collected road from the VICS center 3 side (hereinafter referred to as a transmission restriction instruction) is transmitted to the navigation device 1 and collected according to the transmission restriction instruction on the navigation device 1 side. It is good also as a structure which does not transmit the probe information about a completed road.

  In this case, a transmission restriction instruction may be transmitted from the transmission unit 38 of the VICS center 3 together with information (for example, link ID) for identifying the collected road. Further, the control device 26 of the navigation device 1 may prevent the transmitter / receiver 25 from transmitting the probe information on the collected road according to the link ID received from the VICS center 3 and the transmission restriction instruction. In addition, by including information on a period during which probe information about a collected road is not transmitted in the transmission restriction instruction, probe information about a collected road is not transmitted for a certain period (for example, one day). You may do it. Furthermore, when provision of probe information becomes necessary, an instruction for canceling the transmission restriction instruction from the VICS center 3 may be transmitted to the navigation device 1 to enable provision of probe information.

  Moreover, in the above-mentioned embodiment, although the structure which applies the vehicle-mounted terminal of a claim to the navigation apparatus 1 was shown, it does not necessarily restrict to this. The vehicle-mounted terminal according to the claims may be applied to vehicle-mounted devices other than the navigation device 1 as long as the vehicle-mounted device can acquire travel information and position information and can be connected to a communication device.

  Furthermore, in the above-described embodiment, the configuration in which the probe information management apparatus according to the claims is applied to the server that configures the VICS center 3 has been described. However, the configuration is not necessarily limited thereto. For example, the probe information management apparatus according to the claims may be applied to a server constituting a center that distributes road traffic information other than the VICS center.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.
