(Embodiment 1)
In the travel route grasping system of this embodiment, route history information is transferred between a plurality of information processing devices provided at an ETC gate on a toll road. Specifically, the information processing device can grasp the travel route of the vehicle by sequentially taking over the route history information of the vehicle to the next information processing device along a predetermined direction in which the vehicle travels. Further, in the travel route grasping system of the present embodiment, the information processing apparatus deletes the route history information in the own device after transmitting the route history information to another information processing device.

  FIG. 1 is a diagram illustrating an example of the overall configuration of a travel route grasping system 100 according to the present embodiment. As shown in FIG. 1, the travel route grasping system 100 includes ITS spots 10a1, 10a2, 10b, 10c1, 10c2, and 10d, an entrance ETC gate 30, exit ETC gates 35a, 35b, and 35c, and information processing devices 20a to 20c. 20d.

  The road to which the travel route grasping system 100 of the present embodiment is applied is, for example, a toll road on which a vehicle travels in a predetermined direction. That is, FIG. 1 shows an example of the configuration of a travel route grasping system 100 in a lane on a toll road where a vehicle travels in a predetermined direction (for example, a direction from left to right in FIG. 1). It is assumed that another traveling route grasping system 100 is applied to the side. The predetermined direction includes, for example, an upward direction and a downward direction of an expressway, but may be a direction in which a vehicle travels along a toll road.

  FIG. 1 also shows vehicles 1a to 1d traveling on a toll road. Hereinafter, when the vehicles are not particularly distinguished, they are simply referred to as vehicles 1. Each vehicle 1 is equipped with a vehicle-mounted device for DSRC (Dedicated Short Range Communication) and a vehicle-mounted device for ETC.

  In the present embodiment, an example in which the vehicle-mounted device ID of the vehicle-mounted device for ETC or the vehicle-mounted device for DSRC mounted on the vehicle 1 is used as vehicle identification information that can identify the vehicle 1 will be described. In this embodiment, the vehicle-mounted device ID is used, but any information may be used as long as it is information for identifying the vehicle.

  In addition, the toll road to which the travel route grasping system 100 of the present embodiment is applied has a plurality of entrances and exits from upstream to downstream in a predetermined direction (for example, upward or downward) in which the vehicle 1 travels. It has been.

  The entrance ETC gate 30 is a device capable of wirelessly communicating with an on-board device for ETC installed in the vehicle 1 provided at the entrance of a toll road. The entrance ETC gate 30 of this embodiment acquires (receives) the vehicle-mounted device ID of the vehicle 1 when the vehicle 1 passes through the entrance.

  The exit ETC gates 35a, 35b, and 35c are devices capable of wireless communication with an on-board device for ETC installed in the vehicle 1 provided at the exit of the toll road. Hereinafter, when the exit ETC gates 35a, 35b, and 35c are not particularly distinguished, they are simply referred to as the exit ETC gate 35. The exit ETC gate 35 of the present embodiment acquires (receives) the vehicle-mounted device ID of the vehicle 1 when the vehicle 1 passes through the exit. The entrance ETC gate 30 and the exit ETC gate 35 are an example of a gate device in the present embodiment.

  The information processing devices 20a to 20d are associated with the entrance ETC gate 30 or the exit ETC gate 35, and are installed at the entrance and exit of the toll road, respectively. Hereinafter, when the information processing devices 20a to 20d are not particularly distinguished, they are simply referred to as the information processing device 20. The information processing apparatus 20 includes a CPU, a storage device such as a ROM and a RAM, and an external storage device such as an HDD, and has a hardware configuration using a normal computer.

  The information processing apparatus 20 is connected to another information processing apparatus 20 located upstream and downstream by a network (not shown) so as to be able to communicate with each other.

  A plurality of ITS spots 10a1, 10a2, 10b, 10c1, 10c2, and 10d are provided on the toll road from upstream to downstream in a predetermined direction in which the vehicle 1 travels. Hereinafter, when the ITS spots 10a1, 10a2, 10b, 10c1, 10c2, and 10d are not particularly distinguished, they are simply referred to as ITS spots 10. The ITS spot 10 is an example of a communication device in the present embodiment.

  The ITS spot 10 provides various information services to the driver of the vehicle 1 by performing two-way wireless communication with the DSRC in-vehicle device mounted on the vehicle 1. For example, the information service provided from the ITS spot 10 allows the driver of the vehicle 1 to receive services such as dynamic route guidance for selecting an appropriate route and safe driving support.

  In addition, each ITS spot 10 of the present embodiment is associated with one of the information processing apparatuses 20 and is communicably connected via a network (not shown). The information processing apparatus 20 to which the ITS spot 10 is associated is installed in association with the entrance ETC gate 30 or the exit ETC gate 35 located on the downstream side of the ITS spot 10. In other words, each ITS spot 10 is managed by the information processing apparatus 20 located on the downstream side of the own apparatus. In addition, a route on which the ITS spot 10 managed by the information processing device 20 is installed is also referred to as a route managed by the information processing device 20.

  The ITS spot 10 of the present embodiment performs wireless communication with the DSRC in-vehicle device of the vehicle 1 when the vehicle 1 traveling on the toll road enters the wireless communication range of the ITS spot 10.

  A destination to which one ITS spot 10 transmits the vehicle-mounted device ID is one information processing device 20, but each information processing device 20 may receive the vehicle-mounted device ID from a plurality of ITS spots 10. For example, in FIG. 1, the ITS spot 10a1 and the ITS spot 10a2 are associated with the information processing apparatus 20a and transmit the vehicle-mounted device ID of the vehicle 1b to the information processing apparatus 20a.

  In the travel route grasping system 100 of the present embodiment, the entrance ETC gate 30, the ITS spot 10, and the exit ETC gate 35 set the vehicle-mounted device ID of the vehicle 1 at each point from when the vehicle 1 enters the toll road until it exits. Each information processing device 20 sequentially acquires information that the vehicle 1 has passed each point to the next information processing device 20 so that the travel route of the vehicle 1 is grasped.

  For example, when the information processing device 20d of the entrance ETC gate 30 acquires a predetermined vehicle-mounted device ID, the route history information of the vehicle 1 indicated by the vehicle-mounted device ID is generated. Then, after the route history information of the vehicle 1 generated by the information processing device 20d is transferred to the information processing device 20a, the information processing device 20a receives information (in other words, information that the vehicle 1 travels on the route 40). Information indicating that the vehicle 1 is detected in the ITS spots 10a1 and 10a2 provided on the route 40 between the processing device 20d and the information processing device 20a) is added to the route history information of the vehicle 1. Then, the information processing device 20a passes the route history information of the vehicle 1 to the information processing device 20b. Then, the information processing device 20b adds information that the vehicle 1 travels on the route 41 to the route history information of the vehicle 1. As a result, information on the route 40 and the route 41 is included as the route history information of the vehicle 1. The traveling route of the vehicle 1 can be grasped by repeating such processing.

Hereinafter, the details of the ITS spot 10 and the information processing apparatus 20 of the present embodiment will be described.

  The storage unit 250 is, for example, an HDD. As shown in FIG. 2, the storage unit 250 stores a route history database (DB) 50 and a route-specific fee database (DB) 51.

  The route history database 50 stores the vehicle-mounted device ID, the route name (point name) through which the vehicle 1 has passed, and the reception time (passage time) in association with each other. The information for each vehicle-mounted device ID stored in the route history database 50 is referred to as route history information.

  The route name is an example of information indicating a route where the entrance ETC gate 30 or each ITS spot 10 where the vehicle-mounted device ID of the vehicle 1 is acquired is installed. For example, the route name is the name of the entrance through which the vehicle 1 has passed or the name of the position where the ITS spot 10 that has detected the vehicle 1 is installed, but may be any information that can identify the travel route of the vehicle 1. It is not limited.

  The reception time is the time when the information processing apparatus 20 receives the vehicle-mounted device ID from the entrance ETC gate 30 or each ITS spot 10.

In the route-specific fee database 51 of the present embodiment, different fees can be set for each route on which the vehicle 1 has traveled. Further, different fees may be set in the route-specific fee database 51 according to the vehicle type, traffic time zone, and the like.

  The ITS receiving unit 201 receives the vehicle-mounted device ID from the ITS spot 10. Further, the ITS receiving unit 201 searches the route history database 50 with the received vehicle-mounted device ID to determine whether or not the received vehicle-mounted device ID has already been received. The ITS receiving unit 201 is an example of a first receiving unit in the present embodiment.

  The ETC receiving unit 202 receives the vehicle-mounted device ID of the vehicle 1 that has passed through the entrance or exit from the entrance ETC gate 30 and the exit ETC gate 35.

  The request unit 203 is associated with the vehicle-mounted device ID received by the ITS receiving unit 201 with respect to the information processing device 20 closest to the own device among the other information processing devices 20 provided upstream of the own device. Request (inquire) route history information. Moreover, the request | requirement part 203 requests | requires path | route history information only at the time of the first reception, when the ITS receiving part 201 receives the same onboard equipment ID in multiple times. In the present embodiment, the information processing device 20 provided upstream is also referred to as an upstream information processing device, and the information processing device 20 provided downstream is also referred to as a downstream information processing device.

  The upstream information processing apparatus to which the request unit 203 transmits a request is determined in advance. For example, the upstream information processing apparatus may be stored in the storage unit 250 as a request destination.

  The receiving unit 204 receives route history information associated with the vehicle-mounted device ID requested by the requesting unit 203 from the information processing device 20. The receiving unit 204 is an example of a second receiving unit in the present embodiment.

  When the ETC reception unit 202 receives the vehicle-mounted device ID from the entrance ETC gate 30, the registration unit 205 generates route history information corresponding to the vehicle-mounted device ID and registers it in the route history database 50.

  In addition, when the ITS receiving unit 201 receives the vehicle-mounted device ID from the ITS spot 10, the registration unit 205 adds the route name (vehicle-mounted) that the device itself has to the route history information received from the upstream information processing device by the receiving unit 204. The route name where the ITS spot 10 that received the device ID is installed) and the reception time when the vehicle-mounted device ID is received from the ITS spot 10 are added and registered in the route history database 50.

  The request receiving unit 206 receives a request for route history information associated with the vehicle-mounted device ID of the vehicle 1 from another information processing device 20 provided downstream from the own device.

  When the request accepting unit 206 accepts the request (together with the vehicle-mounted device ID), the transmitting unit 207 reads the route history information associated with the vehicle-mounted device ID from the route history database 50, and as the requested route history information. Then, the data is transmitted to another information processing apparatus 20 provided downstream as a request source. Further, the transmission unit 207 deletes the route history information transmitted to the other information processing apparatus 20 provided downstream from the route history database 50.

  When the ETC reception unit 202 receives the vehicle-mounted device ID from the exit ETC gate 35, the calculation unit 208 reads out the route history information associated with the vehicle-mounted device ID from the route history database 50. The calculation unit 208 identifies the travel route of the vehicle 1 from the route history information associated with the vehicle-mounted device ID. Then, the calculation unit 208 uses the route fee database 51 to calculate a toll according to the travel route of the vehicle 1.

  Next, route history information generation processing executed by the travel route grasping system 100 of the present embodiment configured as described above will be described with reference to FIGS.

  FIG. 3 is a flowchart illustrating an example of a procedure of the route history information generation process according to the present embodiment. The process of this flowchart is executed by the information processing apparatus 20 connected to the entrance ETC gate 30. In addition, the processing of this flowchart is repeatedly executed while the information processing apparatus 20 is activated, for example.

  FIG. 4 is a diagram for explaining generation of route history information at the entrance of the toll road according to the present embodiment.

  First, the ETC reception unit 202 of the information processing apparatus 20d determines whether or not the vehicle-mounted device ID is received from the entrance ETC gate 30 (S1). When the vehicle-mounted device ID is not received (S1 “No”), the ETC reception unit 202 repeats the processing of S1 and waits for transmission from the entrance ETC gate 30.

  On the other hand, as shown in FIG. 4, when the vehicle 1 enters the toll road through the entrance D, the entrance ETC gate 30 acquires the vehicle-mounted device ID from the vehicle 1. Then, the entrance ETC gate 30 transmits (notifies) the acquired vehicle-mounted device ID to the information processing device 20d. In this case, as shown in FIG. 3, the ETC receiving unit 202 of the information processing apparatus 20d receives the vehicle-mounted device ID from the entrance ETC gate 30 (S1 “Yes”).

  Then, the registration unit 205 of the information processing device 20d generates route history information by associating the vehicle-mounted device ID, the reception time of the vehicle-mounted device ID, and the entrance name (route name) (S2). In the example shown in FIG. 4, it is assumed that the route history information 401 of the vehicle-mounted device ID “AAAA” is generated.

  The registration unit 205 registers (saves) the generated route history information in the route history database 50 (S3).

  Next, the route history information takeover process executed by the travel route grasping system 100 according to the present embodiment will be described with reference to FIGS.

  FIG. 5 is a flowchart illustrating an example of a procedure of the path history information takeover process according to the present embodiment. The processing of this flowchart is repeatedly executed while the information processing apparatus 20 is activated, for example.

  FIG. 6 is a diagram for explaining transmission / reception of information by the ITS spot 10 and the information processing apparatus 20 according to the present embodiment. The upstream information processing apparatus in FIG. 5 corresponds to the information processing apparatus 20d in FIG. 6, and the downstream information processing apparatus corresponds to the information processing apparatus 20a.

  The ITS receiving unit 201 of the information processing apparatus 20a (downstream information processing apparatus) determines whether or not the vehicle-mounted device ID is received from the ITS spot 10a1 or ITS spot 10a2 managed by the apparatus (S11). When the vehicle-mounted device ID is not received (S11 “No”), the ITS receiving unit 201 repeats the process of S11 and waits for transmission from the ITS spots 10a1 and 10a2.

  When the OBE ID is received (S11 “Yes”), the ITS receiving unit 201 searches the route history database 50 with the received OBE ID to determine whether or not the received OBE ID has already been received. Is determined (S12). When the received vehicle-mounted device ID has not been received (S12 “No”), the request unit 203 is the information processing device 20 closest to the own device among the information processing devices 20 located on the upstream side of the toll road. The information processing device 20d (upstream information processing device) is requested (inquired) for route history information associated with the received vehicle-mounted device ID (S13).

  The request receiving unit 206 of the information processing apparatus 20d determines whether a request (inquiry) for route history information has been received from the information processing apparatus 20a (S21). When the request for the route history information is not received (S21 “No”), the request receiving unit 206 repeats the process of S21 and waits for the request for the route history information.

  When the request reception unit 206 receives a request for route history information (S21 “Yes”), the transmission unit 207 searches the route history database 50 for route history information associated with the requested vehicle-mounted device ID ( S22).

  When the route history information associated with the requested vehicle-mounted device ID is in the route history database 50 (S23 “Yes”), the transmission unit 207 transmits the route history information to the information processing apparatus 20a that is the request source. (S24). Further, the transmission unit 207 deletes the route history information transmitted to the information processing apparatus 20a from the route history database 50 (S25).

  Further, when the route history information associated with the requested vehicle-mounted device ID is not in the route history database 50 (S23 “No”), the transmission unit 207 ends the processing without performing transmission to the information processing device 20a. To do. Alternatively, the transmission unit 207 may transmit a notification that there is no corresponding route history information to the information processing apparatus 20a.

  Returning to the processing of the information processing apparatus 20a, the receiving unit 204 of the information processing apparatus 20a receives the route history information transmitted from the information processing apparatus 20d (S14).

  The registration unit 205 of the information processing device 20a includes, in the received route history information, the route name (route A) where the ITS spot 10a1 managed by the own device is installed, the reception time when the vehicle-mounted device ID is received from the ITS spot 10a1, and Is added (S15). For example, it is assumed that the information 602 to which “X month X day Y hour Z minute: route A” included in the route history information 601 shown in FIG.

  The registration unit 205 registers the route history information to which the route name and the reception time are added in the route history database 50 of the own device (S16). In this embodiment, when the downstream information processing apparatus acquires the path history information from the upstream information processing apparatus and adds and registers the information is referred to as taking over the path history information in this embodiment.

  If the received vehicle-mounted device ID has already been received in the process of S12 (S12 “Yes”), the process of the flowchart ends. For example, in the example of FIG. 6, after the vehicle-mounted device ID of the vehicle 1 transmitted by the ITS spot 10a1 is registered in the route history database 50 of the information processing device 20a, the ITS spot 10a2 processes the vehicle-mounted device ID of the same vehicle 1. When the information is transmitted to the device 20a, the information processing device 20a does not request the route history information to the information processing device 20d.

  Next, fee calculation processing executed by the travel route grasping system 100 of the present embodiment will be described with reference to FIGS.

FIG. 7 is a flowchart illustrating an example of a procedure of fee calculation processing according to the present embodiment.
Moreover, FIG. 8 is a figure explaining the transmission / reception of the information in the exit of the toll road concerning this embodiment.

  In FIG. 8, the vehicle 1 travels on the route (route B) where the ITS spot 10b is installed, and then exits the toll road from the exit where the exit ETC gate 35d is installed. When the vehicle 1 is detected by the ITS spot 10b and the vehicle-mounted device ID is acquired, the vehicle-mounted device ID of the vehicle 1 is transmitted to the information processing device 20b. In addition, the information processing apparatus 20b acquires the route history information associated with the vehicle-mounted device ID of the vehicle 1 from the information processing apparatus 20a according to the procedure described in FIGS. The time is added and registered in the route history database 50.

  In such a state, when the vehicle 1 reaches the exit ETC gate 35d, the exit ETC gate 35d acquires the vehicle-mounted device ID of the vehicle 1 and transmits the acquired vehicle-mounted device ID to the information processing device 20b.

  The ETC receiving unit 202 of the information processing device 20b determines whether or not the vehicle-mounted device ID is received from the exit ETC gate 35d (S31). When the vehicle-mounted device ID is not received (S31 “No”), the ETC reception unit 202 repeats the process of S31 and waits for transmission from the exit ETC gate 35d.

  When the ETC reception unit 202 receives the vehicle-mounted device ID (S31 “Yes”), the calculation unit 208 reads the route history information associated with the vehicle-mounted device ID from the route history database 50 (S32). Then, the calculation unit 208 specifies the travel route of the vehicle 1 from the read route history information, and calculates the toll according to the travel route of the vehicle 1 using the route-specific fee database 51 (S33).

  In the above-described example, the upstream information processing apparatus and the downstream information processing apparatus arranged in a one-to-one relationship transmit and receive route history information. It is not limited. For example, at a point where a plurality of routes merge together, there are a plurality of upstream information processing devices that are request destinations of route history information for downstream information processing devices installed in the route after the merge.

  FIG. 9 is a diagram for explaining transmission / reception of route history information when routes according to the present embodiment merge. In the example shown in FIG. 9, the vehicle 1 travels on the route on which the ITS spot 10e is installed, and then travels on the route on which the ITS spot 10g is installed. In addition to the route where the ITS spot 10e is installed, the route where the ITS spot 10f is installed joins the route where the ITS spot 10g is installed.

  As described in the flowchart of the path history information takeover process in FIG. 5, when the information processing device 20g receives the vehicle-mounted device ID of the vehicle 1 from the ITS spot 10g, the information processing device 20g receives the vehicle-mounted device received by the upstream information processing device. The route history information associated with the ID is requested.

  As illustrated in FIG. 9, the information processing device 20 g installed in the route after the merge is received by both the information processing device 20 e installed in the route before the merge and the information processing device 20 f. The route history information associated with the ID is requested.

  The route history database 50 of the information processing device 20e stores route history information associated with the vehicle-mounted device ID requested from the information processing device 20g. For this reason, the transmission unit 207 of the information processing device 20e transmits the route history information associated with the requested vehicle-mounted device ID to the information processing device 20g.

  On the other hand, since the vehicle 1 is not traveling on the route where the ITS spot 10f is installed, the route history database 50 of the information processing device 20f has a route history associated with the vehicle-mounted device ID requested from the information processing device 20g. Information is not stored. For this reason, the transmission unit 207 of the information processing device 20f does not perform transmission to the information processing device 20g. Or the transmission part 207 may transmit to the information processing apparatus 20g that there is no corresponding route history information.

  As described above, in the travel route grasping system 100 according to the present embodiment, the ITS spot 10 sets the downstream of the vehicle-mounted device ID of the vehicle 1 that has traveled within the wireless communication range among the vehicles 1 traveling on the toll road. The information is transmitted to the information processing apparatus 20 that is provided in advance and associated in advance as a transmission destination from the own apparatus. Further, the information processing device 20 receives the route history information associated with the vehicle-mounted device ID received from the ITS spot 10 from the upstream information processing device provided upstream from the own device, and the received route history information. Add and register the route name under the control of the local device. For this reason, according to the travel route grasping system 100 of the present embodiment, the route history information is taken over and updated between the information processing devices 20 as each vehicle 1 moves, and the latest route is always reflected in the route history information. The processing load and processing time for grasping the travel route for each vehicle 1 can be reduced.

It is not necessary to save, and the amount of data stored on the vehicle-mounted device side can be reduced.

  Furthermore, in the travel route grasping system 100 of the present embodiment, the information processing device 20 receives the requested route history information when receiving a request for route history information associated with the vehicle-mounted device ID from the downstream information processing device. Information is transmitted to the downstream information processing apparatus. For this reason, according to the travel route grasping system 100 of the present embodiment, the amount of data transmitted and received between the information processing apparatuses 20 can be reduced.

  Furthermore, in the travel route grasping system 100 of the present embodiment, when the information processing device 20 is notified of the vehicle-mounted device ID from the entrance ETC gate 30, the information processing device 20 generates route history information corresponding to the vehicle-mounted device ID and generates a route history. Register in the database 50. That is, in this embodiment, since the route history information is generated for each vehicle 1, the information processing apparatus 20 can reduce the processing load for specifying the route history information of the vehicle 1.

The route is specified, and the toll according to the travel route is calculated. For this reason, according to the travel route grasping system 100 of the present embodiment, it is possible to reduce the processing load and charge the vehicle 1 with a toll for each route.

  Furthermore, in the travel route grasping system 100 of the present embodiment, the information processing device 20 deletes the route history information transmitted to the downstream information processing device from the route history database 50. For this reason, according to the travel route grasping system 100 of the present embodiment, an increase in the amount of data stored in the route history database 50 can be suppressed.
