FIG. 4 is a flowchart showing the driving support process according to the embodiment, and FIGS. 5 and 6 are conceptual diagrams illustrating the driving support process. At this time, in FIG. 3, the same member numbers as the respective constituent members in the information processing apparatus S are used for the respective constituent members in the examples corresponding to the respective constituent members in the information processing apparatus S according to the embodiment shown in FIG. 1. ing.

  As shown in FIG. 2, the inter-vehicle communication system CS according to the embodiment is a terminal device SS that is mounted on a vehicle C, and various types can be obtained by mutual connection via direct wireless communication via an antenna AT. The terminal device SS is configured to be able to exchange data. Here, in the terminal device SS that constitutes the inter-vehicle communication system CS, the terminal device SSa according to the embodiment in which the map data for guidance itself is recorded, and the terminal that does not itself record the map data Device SSb. In the following description, when a matter common to the terminal device SSa and the terminal device SSb is described, it is simply indicated as “terminal device SS”.

  Next, the structure and outline | summary operation | movement are demonstrated about the terminal device SSa which concerns on an Example using FIG.

  As illustrated in FIG. 3, the terminal device SSa according to the embodiment includes an interface 1 connected to an antenna AT, a CPU, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. A processing unit 10 corresponding to an example of "means" and an example of "second determination means", a recording unit 11 having a volatile area and a non-volatile area, in which the map data for guidance is recorded, and an operation An operation unit 12 including buttons or a touch panel, a sensor unit 13 including various sensors for detecting a current position and a traveling direction of a vehicle C including a terminal device SS, a speed and a travel distance, and guidance by the terminal device SSa A display 14 that includes a liquid crystal display or the like for displaying a guidance image, a map image, or the like necessary for processing, and corresponds to an example of a “display unit” according to the present application; And it is made of. At this time, the interface 1 corresponds to an example of the first acquisition unit 1, an example of the second acquisition unit 2, and an example of the third acquisition unit 5 according to the embodiment.

  The processing unit 10 includes a determination unit 3 that corresponds to an example of the determination unit 3 according to the embodiment, and a notification unit 4 that corresponds to an example of the notification unit 4 according to the embodiment. At this time, each of the determination unit 3 and the notification unit 4 may be realized by a hardware logic circuit constituting the processing unit 10, or the processing unit 10 reads and executes a driving support processing program described later. It may be executed by software. Furthermore, the interface 1 and the determination unit 3 and the notification unit 4 of the processing unit 10 constitute an example of the information processing apparatus S according to the embodiment (see the broken line in FIG. 3).

  In the above configuration, the interface 1 controls the exchange of data with other terminal devices SS under the control of the processing unit 10. The recording unit 11 temporarily stores data and the like necessary for the processing unit 10 to execute the driving support process according to the embodiment, and stores the map data and the like, and reads them as necessary. Further, the sensor unit 13 detects the current position of the terminal device SS, for example, autonomously or by receiving a navigation radio wave from a GPS (Global Positioning System) navigation satellite, and obtains current position data indicating the current position. Output to the processing unit 10. The sensor unit 13 autonomously detects the speed, traveling direction, travel distance, and the like of the vehicle C, and outputs speed data indicating the speed to the processing unit 10. Further, the operation unit 12 performs an operation corresponding to the operation or the like by performing an operation or the like for designating an operation (such as an operation of the driving support process or an operation of the guidance process according to the embodiment) as the terminal device SS. The signal is output to the processing unit 10. Thus, the processing unit 10 executes the guidance process and the driving support process according to the embodiment while displaying necessary information or a map image on the display 14. At this time, the driving support process is executed mainly by the determination unit 3 and the notification unit 4 of the processing unit 10.

  Next, the driving support process according to the embodiment will be described more specifically with reference to FIGS. Note that the driving support process according to the embodiment is started with, for example, a start operation performed on the operation unit 12 as a trigger. In the following description, the vehicle C on which the terminal device SSa on which the driving support process shown in FIGS. 3 to 6 is executed is indicated as “own vehicle C0”. Further, other vehicles C, which will be described later, other than the host vehicle C0 are denoted as a vehicle C1, a vehicle C2, a vehicle C3,..., A vehicle Cn (n is a natural number). It should be noted that the common items for the own vehicle C0 to vehicle Cn are simply indicated as “vehicle C”.

  That is, as shown in FIG. 4, for example, when the start operation is performed as illustrated in FIG. 4, the processing unit 10 first starts the processing unit 10 with the terminal device SSa or the terminal device SSb of another vehicle Cn via the interface 1 and the antenna AT. Data necessary for the driving support process is acquired by direct wireless communication (vehicle-to-vehicle communication) with the vehicle (step S1). The data acquired from the other terminal device SSa having the map data in step S1 includes, for example, transmission source identification data, destination identification data, current position data, type data, shape data, intersection data, and trajectory data. ing. At this time, the transmission source identification data is data for identifying the vehicle C on which the other terminal device SS is mounted from the other vehicle C. The destination identification data is data for identifying the host vehicle C0 on which the terminal device SSa that is a transmission destination (destination) is mounted from another vehicle Cn. Furthermore, the current position data is data indicating the current position of the vehicle Cn on which the other terminal device SSa is mounted. The type data is data indicating the type of road on which the vehicle Cn is currently traveling (for example, a type indicating whether the vehicle Cn is traveling on a general road or an expressway). Further, the shape data is data indicating the shape of the road on which the vehicle Cn is currently traveling, for example, by so-called link data and node data. The intersection data is data indicating the position of the intersection closest to the traveling direction on the road on which the vehicle Cn is currently traveling, the distance and direction to the intersection, the shape of the intersection, the presence or absence of a signal at the intersection, and the like. . Further, the trajectory data is data indicating a travel history (travel trajectory) of the vehicle Cn. The type data, shape data, and intersection data are transmitted because the vehicle Cn on which the terminal device SSa is mounted records map data for guidance processing.

  On the other hand, the data acquired from the other terminal device SSb having no map data in step S1 includes, for example, transmission source identification data, destination identification data, current position data, locus data, and the like. Compared with the data transmitted from the terminal device SSa, the data transmitted due to the recording of the map data or the like is not included.

  When reception of various data is started in step S1, the processing unit 10 next has a terminal in which the terminal device SS of the other vehicle Cn that is the transmission source of the various data records map data including road data. It is determined whether or not the device is SSa (step S2). In the determination of step S2, when the terminal device SS of the other vehicle Cn that is the transmission source is the terminal device SSa that records map data or the like (step S2; YES), the processing unit 10 transmits from the terminal device SSa. The current position of the vehicle Cn and the road on which the vehicle Cn is traveling are identified using the type data and the shape data, etc. that have been used (see step S1). For example, position data indicating the position of the vehicle Cn is Processing such as matching with road data is performed (step S3), and then the process proceeds to step S10 described later.

  On the other hand, if it is determined in step S2 that the terminal device SS of the other vehicle Cn that is the transmission source is not the terminal device SSa that records map data or the like (that is, the terminal device SSb) (step S2; NO), the processing The determination unit 3 of the unit 10 compares the map data recorded in the recording unit 11 of the own vehicle C0 with the current position of the other vehicle Cn, and a plurality of roads are located near the current position of the other vehicle Cn. It is determined whether or not there is (step S4). When there is only one road near the current position of the other vehicle Cn in the determination in step S4 (step S4; NO), the determination unit 3 corresponds to the other vehicle Cn on the road (that is, the vehicle Cn travels). In addition, it is determined that the road is a road and, for example, processing such as matching the position data indicating the position of the vehicle Cn with the road data is performed (step S5), and the process proceeds to step S10 described later.

  Here, the “near” in the step S5 is the maximum value of the “near”, for example, the range of the “estimated error amount” defined by the standard related to the conventional inter-vehicle communication system. The determination according to step S4 may be performed within this range. Further, a value obtained by adding a certain value (for example, 10 meters) to the range may be set as the maximum value of “near”, or a fixed value of, for example, 20 meters may be set as the range (maximum value) in the vicinity. . Further, for example, as the standard, the data exchanged by inter-vehicle communication includes data such as “horizontal error of 20 meters” as “error estimation amount” in addition to the current position data. If there are a plurality of roads within the error range, the determination in step S4 can be performed. Further, a value obtained by adding a certain range (for example, 10 meters) to the estimated error amount (for example, “20 meters in the horizontal direction”) may be used, or the terminal device of the host vehicle C0 separately from the estimated error amount. You may utilize the fixed value (for example, 15 meters) preset by SSa.

  Furthermore, when step S4 and step S5 are executed, for example, as shown in FIG. 5A, a road R1 intersecting with a road R2 on which the vehicle C0 is traveling via an intersection CR is displayed. The road on which the traveling vehicle C1 (the terminal device SS mounted therein is a terminal device SSb in which no map data or the like is recorded) is determined as the road R1 (see step S5 in FIG. 4). For example, the incorrect current position C1 ′ is matched with the correct current position C1.

On the other hand, when there are two or more roads in the vicinity of the current position of the other vehicle Cn in the determination in step S4 (step S4; YES), the determination unit 3 next includes the past in the data transmitted from the vehicle Cn. It is determined whether or not the trajectory data indicating the movement history is included (step S6). When the trajectory data is included in the determination in step S6 (step S6; YES), the determination unit 3 next determines whether there are a plurality of roads near the position of the latest trajectory data (step S8). . The meaning of “near” in the determination in step S8 is the same as in step S4. In the determination in step S8, when there are two or more roads in the vicinity of the trajectory data currently targeted (step S8; YES), the determination unit 3 further determines the number of roads in the vicinity by tracing the trajectory data further to the past. Accordingly, the process returns to the determination in step S6. On the other hand, if it is determined in step S8 that there is only one road in the vicinity of the current trajectory data (step S8; NO), the determination unit 3 next selects the current vehicle Cn from the road indicated by the trajectory data. It is determined whether or not there is only one connecting road that reaches the position (step S9). At this time, by repeating the process of step S6; YES → step S8; YES → step S6, for example, as shown in FIG. 5B, the past position C1 _Pm (m is a natural number) of another vehicle C1, for example. ) Are traced back as trajectory data until there is only one surrounding road R1. That is, in the case illustrated in FIG. 5B, the past position C1 _P2 is traced back from the past position C1 _P1 to the past position C1 _P3 . Then, the road R1 including the past position C1 _Pm targeted at the time when the determination in step S8 becomes “YES” is the road on which the vehicle Cn was traveling at that time in the past. It is determined.

  Here, for example, when the highway H and the road R1 illustrated in FIG. 5B are parallel over a long distance, for example, the number of other vehicles Cn to be processed at one time and the processing unit 10 In view of the processing capacity and the like, it is preferable that the processing is terminated (canceled) when the number of trajectory data corresponding to the processing capacity is traced back. At this time, in the standard of inter-vehicle communication, for example, when the current position data is exchanged every 100 milliseconds, and there are ten vehicles Cn that have transmitted data by inter-vehicle communication, Since the processing time of 10 milliseconds can be used for each table, it is preferable to discontinue the processing when the processing illustrated in FIG. 5B is not completed within 10 milliseconds. On the other hand, when only one vehicle has transmitted data by inter-vehicle communication, a processing time of 100 milliseconds can be used for each vehicle, so the processing does not end within 100 milliseconds. If this happens, the process can be terminated.

Next, when there is only one connecting road from the road indicated by the trajectory data to the current position of the other vehicle Cn in the determination of step S9 (step S9; YES), the determination unit 3 uses the trajectory data. As a result of the vehicle Cn continuously traveling on the road determined in this way (the road R1 in the case of FIG. 5B), it is determined that the current position is also on the road R1, and the current position is determined on the own vehicle C0. Is notified to the user (driver or passenger, the same applies hereinafter) of the vehicle C0, such as alerting the vehicle Cn (step S10), and then the process proceeds to step S11 described later. Determining unit 3 at this time, for example, as shown in FIG. 6 (a), for example, after matching in past positions _{C1 P1} from past position C1 _'P1 to past locations _{C1 P1,} for continuously road R1 Matching is continued until the current position C1 ′ is matched with the correct current position C1 on the road R1, for example. Moreover, as an actual timing which performs the alerting | reporting which concerns on the said step S10, for example, when the other vehicle Cn goes straight on the opposite lane when the own vehicle C0 turns right, it is for pedestrians near the own vehicle C0. When there is an intersection, when the own vehicle C0 and another vehicle Cn are traveling at the timing of meeting at the intersection, when the vehicle Cn as a construction vehicle is approaching, the own vehicle C0 can be involved when turning left There are cases where there is a characteristic vehicle Cn (for example, a motorcycle) or a case where a vehicle Cn as an emergency vehicle is approaching. Further, as the contents of the notification relating to the above step S10, for example, highly reliable information that may lead to an accident is displayed, for example, “Other vehicle approaches straight when turning right”, “Vehicle comes from right”, etc. Examples include interrupt information, an operation instruction such as “depress the brake now”, and an information display in which a position mark indicating the current position of the vehicle Cn is superimposed on a map and displayed on the display 14.

  On the other hand, if it is determined in step S9 that there are two or more connecting roads from the road indicated by the trajectory data to the current position of the other vehicle Cn (step S9; NO), for example, the interchange IC shown in FIG. Thus, it is impossible to determine whether the vehicle Cn is currently traveling on the road R1 or the highway H. Therefore, in this case, the notification unit 4 does not perform notification (warning) using the current position of the vehicle Cn, and for example, makes it possible for the user to determine when it is not possible to clearly determine whether an accident will occur immediately. Information is displayed, for example, providing information such as “there is a vehicle C1 approaching the host vehicle C0”, displaying the position of another vehicle on a map, etc. (step S7).

  Thereafter, the processing unit 10 determines whether or not to end the driving support process according to the embodiment, for example, because the power of the terminal device SSa is turned off or the own vehicle C0 has reached the destination (for example). Step S11). When the driving support process is continued in the determination in step S11 (step S11; NO), the processing unit 10 returns to step S1. On the other hand, when the driving support process according to the embodiment is ended in the determination of step S11 (step S11; YES), the processing unit 10 ends the driving support process as it is.

  Note that, when the trajectory data is not included in the data from the vehicle Cn in the determination in step S6 (step S6; NO), the determination unit 3 proceeds to step S7.

  As described above, according to the operation of the inter-vehicle communication system CS according to the embodiment, the road R1 on which the other vehicle Cn is traveling is based on the map data, the current position data, and the trajectory data. Based on the road R1, the notification regarding the relationship between the host vehicle C0 on which the terminal device SSa is mounted and the other vehicle C is performed (see step S10 and step S7 in FIG. 4). Therefore, for example, even when the current position of another vehicle Cn cannot be specified by the relationship with the map data, the user can recognize the relationship with the other vehicle Cn.

  Further, when the number of roads related to the position of the other vehicle Cn is determined based on the current position data and the map data, and the number is determined to be one (see FIG. 5A), the determined road R1 is determined to be a road R1 on which another vehicle C is moving. When it is determined that the number is two or more, the road R1 on which another vehicle Cn is traveling is determined based on the trajectory data (see FIG. 5B). Therefore, even when there are two or more roads related to the current position of the other vehicle Cn, the road R1 on which the other vehicle Cn is moving can be determined based on the trajectory data.

  Further, when it is determined that the number of roads related to the position of the other vehicle Cn is one, the number of roads that reach the position corresponding to the current position of the other vehicle Cn from the road for which the number is determined is two or more. In such a case, only information provision or the like that does not require identification of the current position of the other vehicle Cn is notified (see step S7 in FIG. 4). Therefore, even when the current position of the other vehicle Cn cannot be specified, it is possible to provide minimum information.

  Furthermore, when the map showing the road R1 determined that the other vehicle Cn is traveling is displayed on the display 14, the relationship with the other vehicle Cn can be clearly recognized.

  In the above-described embodiments, the case where the present application is applied to the inter-vehicle communication system CS using inter-vehicle communication has been described. However, other than this, for example, via a network such as the Internet (that is, a predetermined server device is installed). It is also possible to apply the present application to a communication system that exchanges data between vehicles C). In this case, the terminal devices SS exchange data while identifying each other using the transmission source identification data and the like.

  Further, in the above-described embodiments, the case where the present application is applied to the inter-vehicle communication system CS that uses inter-vehicle communication has been described. However, in addition to this, for example, a portable that is carried by a person as an example of a mobile object according to the embodiment It is also possible to apply the present application to a system that supports movement of a person who carries a portable information terminal device while performing communication between the portable information terminal devices (including so-called smartphones). In this case, necessary data is exchanged between portable information terminal devices while identifying each other using identification data for identifying each other.

  Furthermore, a driving support program corresponding to the flowchart shown in FIG. 4 is recorded on a recording medium such as an optical disk or a hard disk, or is acquired via a network such as the Internet, and is used as a general-purpose microcomputer. It is also possible to cause the microcomputer or the like to function as the processing unit 10 according to the embodiment by reading and executing the above.
