Further, the interface 1, the movement determination unit 2 of the processing unit 10, and the support unit 5 constitute an example of the movement support device 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 another terminal device SSb under the control of the processing unit 10. Further, the memory 11 temporarily stores data and the like necessary for the processing unit 10 to execute the traveling support process according to the embodiment, and causes the memory 11 to read out as necessary. Further, the sensor unit 13 detects the current position of the terminal device SSa by, for example, autonomously or by a method such as receiving a navigation radio wave from a GPS (Global Positioning System) navigation satellite, and obtains the current position data indicating the current position.

Further, the operation unit 12 outputs an operation signal corresponding to the operation or the like to the processing unit 10 by executing an operation or the like for designating the operation as the terminal device SSa. As a result, the processing unit 10 executes the traveling support process according to the embodiment while displaying the necessary information on the display 14. At this time, the movement determination unit 2, the necessity determination unit 15, and the support unit 5 of the processing unit 10 play a central role in executing the travel support process.

Next, the traveling support process according to the embodiment will be described more specifically with reference to FIGS. 3 to 5. The traveling support process according to the embodiment is started, for example, triggered by the start operation performed by the operation unit 12. Further, in the following description, when common matters are explained for the vehicle C0 to the vehicle C3 described later, it is simply referred to as "vehicle C".

That is, as shown in FIG. 4, the traveling support process according to the embodiment is, for example, when the start operation is performed, the processing unit 10 first receives between the interface 1 and the terminal device SSb of another vehicle C via the antenna AT. The data required for the driving support process is acquired by direct wireless communication (vehicle-to-vehicle communication) (step S1). The data acquired from the other terminal device SSb by the process of step S1 includes, for example, source identification data, destination identification data, current position data, type data, shape data, intersection data, locus data, distance data, and the like. It has been. Of these, for example, source identification data, destination identification data, current position data, locus data, distance data, etc. correspond to examples of moving body information according to the embodiment, and type data, shape data, intersection data, etc. are implemented. It corresponds to an example of the movement route information related to the form. At this time, the source identification data is data for identifying the vehicle C on which the terminal device SSb is mounted from other vehicles C. Further, the destination identification data is data for identifying a vehicle C on which a terminal device SSa, which is a transmission destination (destination), is mounted from another vehicle C. Further, the current position data is data indicating the current position of the vehicle C on which the terminal device SSb is mounted. Further, the type data is data indicating the type of the road on which the vehicle C is currently traveling (for example, the type of whether the vehicle C is traveling on a general road or a highway). Further, the shape data is data showing the shape of the road on which the vehicle C is currently traveling by, for example, 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 C is currently traveling, the distance and direction to the intersection, the shape of the intersection, and the presence or absence of a signal at the intersection. be. Further, the locus data is data showing the travel history (travel locus) of the vehicle C. Finally, the distance data is the distance between the vehicle C on which the terminal device SSb is mounted and the vehicle C on which the terminal device SSa is mounted (if both are traveling on the same road in the same direction, both). It is the data showing the distance between vehicles). In this case, the type data, the shape data, and the intersection data are transmitted because the vehicle C on which the terminal device SSb is mounted records the map data for normal guidance.

When the reception of various data is started in step S1, the processing unit 10 next determines whether or not the predetermined amount of data required for the determination of step S3 and step S4, which will be described later, has been acquired. (Step S2). If the required amount of data has not yet been acquired in the determination in step S2 (step S2; NO), the processing unit 10 returns to step S1 and continues to acquire various data. On the other hand, when the required amount of data can be acquired in the determination in step S2 (step S2; YES), the movement determination unit 2 of the processing unit 10 next obtains the data acquired in step S1 and the sensor of the terminal device SSa itself. Based on the current position data and the like output from the unit 13, another vehicle C (another terminal device) traveling on the same road as the vehicle C0 on which the terminal device SSa is currently traveling. It is determined whether or not there is a vehicle C) equipped with SSb (step S3).
In this case, as shown in FIG. 5A, for example, the movement determination unit 2 is on the same road with respect to the vehicle C0 (the traveling locus thereof is the locus TR0) on which the terminal device SSa according to the embodiment is mounted. When the locus data, the shape data, and the current position data indicating the locus TR1 of the vehicle C1 are transmitted from the terminal device SSb mounted on the vehicle C1 traveling in front of the vehicle, the locus data and the shape data are transmitted. The degree of coincidence between the travel locus indicated by and the travel locus of the vehicle C0 is determined, and when the degree of coincidence is equal to or higher than a preset threshold value, the vehicle C1 travels on the same road as the vehicle C0 (own vehicle). It is determined that it is. Similarly, the movement determination unit 2 has the locus data, the shape data, and the locus data indicating the locus TR2 of the vehicle C2 from the terminal device SSb mounted on the vehicle C2 traveling behind the same road with respect to the vehicle C0. When the current position data has been transmitted, the degree of coincidence between the travel locus indicated by the locus data and the shape data and the travel locus of the vehicle C0 is determined, and the degree of coincidence is equal to or higher than a preset threshold value. In addition, it is determined that the vehicle C2 is traveling on the same road as the vehicle C0.

In addition to this, as the determination in step S3, the movement determination unit 2 changes the inter-vehicle distance between the vehicle C1 and the vehicle C0 (or the vehicle) when the distance data is received from the vehicle C1 (or the vehicle C2). When the change in the inter-vehicle distance between C2 and the vehicle C0) is equal to or less than a predetermined threshold value, it is determined that the two vehicles C (vehicle C0 and vehicle C1 or vehicle C0 and vehicle C2) are traveling on the same road. You may.

In the determination of step S3, when there is no other vehicle C traveling on the same road (step S3; NO), the processing unit 10 returns to step S1 and continues to acquire various data. On the other hand, in the determination of step S3, when there is another vehicle C traveling on the same road (step S3; YES), the movement determination unit 2 is next to the vehicle C0 on which the terminal device SSa is mounted. It is determined whether or not there are a plurality of other vehicles C traveling on the same road as the traveling road (step S4). In the determination of step S4, the movement determination unit 2 has the plurality of vehicles C traveling depending on whether or not there are a plurality of vehicles C determined to be traveling on the same road in the determination of step S3. Judge whether or not. For example, in the case of the example shown in FIG. 5A, it is determined that there are two vehicles C1 and C2 traveling on the same road before and after the vehicle C0 (step S4; YES). In the determination of step S4, when there is only one other vehicle C traveling on the same road (step S4; NO), the processing unit 10 returns to step S1 and continues to acquire various data. On the other hand, in the determination of step S4, when there are a plurality of other vehicles C traveling on the same road (step S4; YES), the processing unit 10 next, in the data received from those vehicles C, respectively. For example, it is determined whether or not the contents of the above type data match (step S5). If they do not match in the determination of step S5 (step S5; NO), the types of the roads are different even though they are traveling on the same road, so that the data is received from each vehicle C. The reliability of the data is low. Therefore, in this case, the processing unit 10 returns to step S1 and continues to acquire data. The cause of the determination of "NO" in the determination of step S5 (the cause of the decrease in reliability) is, for example, that the versions of the map data recorded in the vehicle C1 and the vehicle C2 are different. Be done.

On the other hand, if the contents of the data for each type match in the determination in step S5 (step S5; YES), it is determined that the reliability of the received data is high, so that the necessity determination unit of the processing unit 10 is next. Reference numeral 15 indicates whether or not it is necessary to provide driving support to, for example, the driver of the vehicle C0 on which the terminal device SSa is mounted, using the above-mentioned type data and the like received from the vehicle C1 and the vehicle C2 traveling on the same road. If it is determined that there is no such necessity (step S6; NO), the process proceeds to step S8 described later, and if it is determined that the necessity is necessary (step S6; YES). ), The support unit 5 of the processing unit 10 executes driving support according to the determination result (step S7).

Here, the traveling support processing according to steps S6 and S7 will be described with reference to FIG. 5B.

For example, as shown in FIG. 5B, the vehicle C0 on which the terminal device SSa is mounted and the vehicle C1, the vehicle C2, and the vehicle C3 on which the terminal device SSb are mounted are performing vehicle-to-vehicle communication. (See steps S1 to S5 in FIG. 4). It is assumed that the vehicle C0, the vehicle C1 and the vehicle C2 are traveling on the general road in the order illustrated in FIG. 5 (b) in the left direction in FIG. 5 (b). On the other hand, it is assumed that the vehicle C3 is traveling in the middle-upward direction in FIG. 5B on a highway that intersects with the general road on which the vehicle C0 or the like is traveling by an elevated road. At this time, it is determined that the vehicle C1 and the vehicle C2 are traveling on the same road as the vehicle C0 (see step S3; YES and step S4; YES in FIG. 4), but the vehicle C3 is traveling on the same road. Is not determined (see step S3; NO in FIG. 4). Then, the processing unit 10 recognizes that there is an intersection CR1 in the immediate vicinity of the front of the general road on which the vehicle C0 or the like travels based on the intersection data from the vehicle C1 or the vehicle C2, and the front of the highway on which the vehicle C3 travels. It is assumed that the processing unit 10 recognizes that, for example, there is a branch point CR2 for entering the parking area in the immediate vicinity based on the intersection data from the vehicle C3.

In the case illustrated in FIG. 5B, the necessity determination unit 15 of the processing unit 10 is a vehicle C0 traveling on a general road and a vehicle C3 traveling at a high speed intersecting the general road by an elevated road. , It can be determined that there is no possibility of collision at the intersection CR1 and the branch point CR2. Therefore, in this case, the necessity determination unit 15 determines that there is no need for driving support (see step S6; NO in FIG. 4).

On the other hand, for example, it is shown by the above-mentioned type data from the vehicle C3 that the vehicle C3 is traveling on the general road, and the position of the intersection CR1 near the front of the general road on which the vehicle C0 or the like is traveling. When it is determined that the position of the intersection near the front of the general road on which the vehicle C3 travels coincides with the position of the intersection, the necessity determination unit 15 determines that driving support is necessary (step 4 in FIG. 4). See S6; YES). As a result, the support unit 5 executes driving support such as calling attention to the vehicle C3 that may intersect at the intersection CR1 in front by using, for example, the display 14 or the voice output unit (not shown) (FIG. 4, step S7). reference). At this time, for example, when the timing of approach to the intersection CR1 which may intersect each other is different from each other, or when there is no possibility of entering the intersection CR1 at the same time due to the signal switching state at the intersection CR1. The above-mentioned traveling support for the vehicle C3 may not be provided.

When it is determined in the determination of step S6 that there is no need for travel support (step S6; NO), or after the travel support in step S7 is executed, the processing unit 10 receives from another vehicle C in the vehicle C0. Each of the data (including the type data and shape data of the road on which the vehicle C0 is traveling) is transmitted to another vehicle C (for example, the vehicle C3 exemplified in FIG. 5B) (step S8). ..

After that, the processing unit 10 ends the traveling support processing according to the embodiment because, for example, the power of the terminal device SSa is turned off or the traveling support according to the embodiment is set not to be performed. It is determined whether or not to do so (step S9). When the traveling support process is continuously executed in the determination of step S9 (step S9; NO), the processing unit 10 returns to the above step S1. On the other hand, when the travel support process according to the embodiment is terminated in the determination of step S9 (step S9; YES), the processing unit 10 terminates the travel support process as it is.

As described above, according to the operation of the vehicle-to-vehicle communication system CS according to the embodiment, whether or not the current position data or the like is acquired from the other vehicle C and the other vehicle C is moving on the same road. (See Step S3 and Step S4 in FIG. 4), and obtain type data and the like related to the other vehicle C from another vehicle C moving on the same road (see step S1 in FIG. 4). As a result, the necessity of driving support based on the type data and the like is determined (see step S6 in FIG. 4), and when it is determined that driving support is necessary, it is executed (see step S7 in FIG. 4). Therefore, when driving support based on type data or the like from another vehicle C is required, the driving support is executed. Therefore, for example, the terminal device SSa of the vehicle C0 in which the original map data or the like is not recorded is used. Even if there is, it is possible to provide effective driving support for the vehicle C0.

In addition, when it is determined that driving support is necessary, the presence or absence of the intersection CR1 in the traveling direction is determined based on the type data, the intersection data, etc., and the status of the intersection CR1 or the like is output, so that the vehicle can drive accurately. Can provide support.

Further, when the data transmitted from the other vehicle C includes at least one of the track data and the distance data, more specific traveling support can be performed based on these. More specifically, for example, when track data is transmitted, the degree of coincidence with the traveling locus of another vehicle C is detected based on the locus data, and the vehicle C0 and the vehicle C1 etc. are detected based on the degree of coincidence. If it is determined whether or not the vehicle is traveling on the same road, it is possible to accurately determine whether or not each vehicle C is traveling on the same road and provide traveling support. Further, when the distance data is transmitted, even if it is determined whether or not each vehicle C is traveling on the same road based on the change in the inter-vehicle distance indicated by the distance data, the same road is used. It is possible to accurately determine whether or not the vehicle C is traveling and provide driving support.

Furthermore, since the necessity of driving support related to the collision between each vehicle C is determined based on the type data transmitted from the other vehicle C, the necessity of driving support is accurately determined based on the type of road. It can be determined.

Further, since the data received by the terminal device SSa is transmitted to another vehicle C (for example, the vehicle C3 exemplified in FIG. 5B) moving on a road other than the same road (step 4 in FIG. 4). (See S8), the other vehicle C can also perform the same traveling support as the vehicle C0.

In the above-described embodiment, if the determination is "NO" in each of steps S3 to S5, the process returns to step S1, but in addition to this, "NO" is determined in each of steps S3 to S5. Even if it is, it may be configured to shift to the above step S6. In this case, before step S8, if the type data or the like for the road on which the vehicle C0 is traveling can be determined, it is transmitted to another vehicle C, and if the type data or the like cannot be determined, the relevant type data or the like is transmitted. It can be configured not to send.

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

Further, in the above-described embodiment, the case where the present application is applied to the vehicle-to-vehicle communication system CS using the vehicle-to-vehicle communication has been described, but in addition to this, for example, a person carrying the mobile body as an example of the mobile body according to the embodiment has been described. It is also possible to apply the present application to a system that supports the movement of a person carrying the portable information terminal device while communicating between the portable information terminal devices (including a so-called smartphone). In this case, necessary data is exchanged between the portable information terminal devices while identifying each other using identification data or the like that identifies 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 acquired via a network such as the Internet, and this is obtained by a general-purpose microcomputer. It is also possible to make the microcomputer or the like function as the processing unit 10 according to the embodiment by reading and executing the microcomputer or the like.
