At this time, in FIG. 3, the same member numbers as those of the components in the movement support apparatus S are used for the components of the example corresponding to the components in the movement support 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 kinds of data are obtained by interconnection by direct wireless communication via an antenna AT. It is comprised by the terminal device SS which can be exchanged. Here, the terminal device SS constituting the inter-vehicle communication system CS itself records the map data for guidance, and the guidance processing of the vehicle C using this can be performed.

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

  As illustrated in FIG. 3, the terminal device SS according to the embodiment includes an interface 1 connected to an antenna AT, a processing unit 10 including a CPU, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Current location and progress of a vehicle C having a recording area 11 having a sex area and a non-volatile area in which the map data for guidance and the like are recorded, an operation section 12 including operation buttons or a touch panel, and a terminal device SS A sensor unit 13 composed of various sensors for detecting the direction, speed, travel distance, and the like, and a display 14 composed of a liquid crystal display for displaying a guidance image, a map image, etc. necessary for guidance processing by the terminal device SS, , Is configured. At this time, the interface 1 corresponds to an example of the acquisition unit 1 according to the embodiment.

  The processing unit 10 includes the prediction unit 2 according to the embodiment, the example of the “determination unit” according to the present application, and the example of the “calculation unit” according to the present application, and the support unit according to the embodiment. And a support unit 3 corresponding to an example of 3. At this time, each of the prediction unit 2 and the support unit 3 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 prediction unit 2 and the support unit 3 of the processing unit 10 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 other terminal devices SS under the control of the processing unit 10. The recording unit 11 temporarily stores data necessary for the processing unit 10 to execute the driving support process according to the embodiment, records the map data, and the like, and causes the map data to be read 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 prediction unit 2 and the support unit 3 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 SS 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). In addition, when a common matter is described for the own vehicle C0 to the vehicle Cn, it is simply indicated as “vehicle C”.

  In other words, as shown in FIG. 4, for example, when the start operation is performed, the processing unit 10 first performs a communication between the terminal device SS 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) (step S1). The data acquired from the other terminal device SS in step S1 includes, for example, transmission source identification data, destination identification data, current position data, type data, shape data, intersection data, trajectory data, distance data, blinker data, and hazards. Data etc. are included. 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 SS 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 SS 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. is there. The trajectory data is data indicating a travel history (travel trajectory) of the vehicle Cn. Further, the distance data indicates the distance between the vehicles C on which the terminal device SS is mounted (for example, the distance between the vehicles when the host vehicle C0 and the other vehicles Cn are traveling in the same direction on the same road). It is the data shown. The type data, shape data, and intersection data are transmitted because the vehicle Cn on which the terminal device SS is mounted records map data for guidance processing. Finally, the blinker data and the hazard data are data indicating whether the blinker switch and the hazard switch in the other vehicle Cn are turned on or off, respectively. At this time, the winker data also includes data indicating the direction in which the winker is being emitted in the left or right direction of the vehicle Cn.

  When reception of various data is started in step S1, the predicting unit 2 of the processing unit 10 next sets a predetermined range in front of the traveling direction of the host vehicle C0 in which the other vehicle Cn that is the transmission source of the various data is. (Hereinafter referred to as “front region”) (step S2). And in determination of step S2, when the other vehicle Cn does not exist in a front area (step S2; NO), the prediction part 2 transfers to step S8 mentioned later.

  Here, the determination in step S2 is executed by comparing the current position data transmitted from another vehicle Cn and the current position data of the host vehicle C0 output from the sensor unit 13, for example. . The forward region at this time is specifically, for example, 90 ° left and right (180 ° in total left and right) with the current position of the host vehicle C0 as the center and the traveling direction of the host vehicle C0 as the central axis (symmetric axis). And a radius of, for example, a 250-meter sector-shaped front region. Further, the processing unit 10 determines whether or not another vehicle Cn exists for each divided area obtained by dividing the fan-shaped front area every 20 meters along the road on which the host vehicle C0 is traveling. In the following description, the divided area is referred to as a “count area”. Each count area according to the embodiment does not start from the current position of the host vehicle C0. For example, as an intersection, a branch point, an inflow point, or map data in front of the road on which the host vehicle C0 is traveling. Set by the processing unit 10 starting from the node.

  Here, the front area and the count area according to the embodiment will be described more specifically with reference to FIG. In FIG. 5A, for example, when the host vehicle C0 is traveling on the road R0, the count area A1 and the count area A2 are set by the processing unit 10 of the host vehicle C0 as illustrated. In the following description, when the matters common to the count area A1 and the count area A2 are described, they are simply indicated as “count area A”. The width of one count area A (the length in the left-right direction in FIG. 5) is, for example, 20 meters in the case of the front area. Further, as illustrated in FIG. 5A, when there is a road R1 adjacent to the road R0 on which the host vehicle C0 travels, the vehicles C1 to C6 that are in each count area A with the vehicles Cn traveling on the road R1. Is determined in step S2 that the vehicles C1 to C6 are present in the front area of the host vehicle C0 (step S2; YES). As shown in FIG. 5 (b), when there is an intersection CR (more specifically, a branch point or a junction) in the front area set for the own vehicle C0, the count area A includes the intersection CR. It is set so that a total of 20 meters becomes one count area A before and after sandwiching (see count area A2 in FIG. 5B).

  When any vehicle Cn exists in the front area in the determination in step S2 (step S2; YES), the prediction unit 2 next selects the vehicle Cn that has taken out the blinker among the existing vehicles Cn. In the case of the vehicle Cn taking out the turn signal, the direction of the turn signal relative to the traveling direction is detected (step S3). The determination in step S3 is executed based on the turn signal data transmitted from another vehicle Cn, for example. For example, as shown in FIG. 6 (a), the prediction unit 2 detects the vehicle C2, the vehicle C4, and the vehicle C2 that have a turn signal W out of the vehicles Cn existing in the count area A. C5 and vehicle C6 are counted. At this time, in the case illustrated in FIG. 6A, the prediction unit 2 counts “one vehicle C with a turn signal on the right” for the count area A1. Further, for the count area A2 that is farther from the count area A1 when viewed from the host vehicle C0, the count is “three vehicles C that have blinkers on the right”. For example, when three or more vehicles Cn are taking out the winkers W in the same direction, the processing unit 10 has the winkers because the three vehicles are approaching a specific point (for example, an inflow point or an intersection CR). Recognize that W is issued. When there is no vehicle Cn which has taken out the turn signal W in the determination in step S3 (step S3; NO), the processing unit 10 proceeds to step S8 described later.

  On the other hand, if it is determined in step S3 that there is a vehicle Cn that is emitting the blinker W and a method for ejecting the blinker W is detected (step S3; YES), the prediction unit 2 then records, for example, Based on the map data or the like recorded in the section 11, it is determined whether there is another road connected in front of the road on which the host vehicle C0 is traveling (step S4). Here, the other road is connected to the road on which the vehicle C0 is traveling, for example, at an intersection CR, a branch point, or an inflow point. In the following description, the other connected road is referred to as a unit “connection road”. When the connecting road is not ahead in the determination in step S4 (step S4; NO), the support unit 3 of the processing unit 10 determines that the vehicle Cn that has emitted the turn signal W in the count of step S3 is driven by the host vehicle C0. In order to avoid obstacles such as falling objects on the road, it is determined that the turn signal W has been put out, and guidance processing such as alerting to that effect is executed using the display 14, for example (step S9). In this case, the support unit 3 displays a warning such as “There is a possibility of a falling object in the front. Thereafter, the processing unit 10 proceeds to Step S8 described later.

  On the other hand, if it is determined in step S4 that the connection road is ahead (step S4; YES), the prediction unit 2 determines that the current position of the host vehicle C0 relates to the connection road based on the current position data from the sensor unit 13, for example. It is determined whether or not it is near the branch point (step S5). At this time, as illustrated in FIG. 6B, for example, the prediction unit 2 turns the blinker W in both the count area A2 including the front intersection CR and the count area A1 adjacent to the count area A2. When there is a vehicle C2 to a vehicle C5 that has issued the vehicle, it is determined that the current position of the host vehicle C0 is near the branch point (intersection CR). If it is determined in step S5 that the current position of the vehicle C0 is near the branch point (step S5; YES), the support unit 3 proceeds to step S8 described later without executing any guidance processing. On the other hand, if it is determined in step S5 that the current position of the host vehicle C0 is not near the branch point (step S5; NO), the predicting unit 2 next determines that the connecting road whose presence is determined in the determination in step S4 is ahead. It is determined whether the road is a connecting road that flows into the road on which the vehicle C0 travels with the intersection CR as an inflow point (step S6). The determination in step S6 is performed by a method similar to the method for determining whether or not the vehicle is near the branch point in step S5. In addition, in the determination in step S6, the prediction unit 2 determines whether or not the vehicle Cn has a turn signal W on the opposite side to the direction in which the connection road is connected, in addition to whether or not the connection road flows in front. Judge whether there is any. That is, for example, when there is a connecting road connected from the left in the traveling direction, the predicting unit 2 is a vehicle Cn that emits a blinker W in the right direction in the vehicle Cn existing in the front area at that time. Whether or not there is is determined together.

  If it is determined in step S6 that there is an inflowing connection road (step S6; YES), the support unit 3 provides a merge guidance indicating that the connection road exists in accordance with the direction in which the connection road flows. Execute (Step S10). In this step S10, for example, if there is a connecting road flowing in from the left (see step S6; YES), the support unit 3 “There is a merge from the left. Please move to the right lane. Is displayed on the display 14 together with a symbol mark indicating a connecting road flowing in from the left side, for example.

  On the other hand, if it is determined in step S6 that there is no incoming connecting road (step S6; NO), the prediction unit 2 next determines that the point where the turn signal W is emitted in the forward vehicle Cn is within the forward junction point. It is determined whether it is before the merge point (step S7). In the determination in step S7, when the point where the turn signal W is emitted in the vehicle Cn ahead is in the front junction or in front of the junction (step S7; YES), the support unit 3 performs the above step S10. The same merging guidance is executed. On the other hand, in the determination of step S7, when the point where the turn signal W is emitted in the vehicle Cn ahead is not within the front junction point and before the junction point (step S7; NO), the prediction unit 2 next For example, it is determined whether or not the driving support process according to the embodiment is to be ended due to the power of the terminal device SS being turned off (step S8). When the driving support process is continued in the determination in step S8 (step S8; NO), the prediction unit 2 returns to step S1. On the other hand, when the driving support process according to the embodiment is ended in the determination in step S8 (step S8; YES), the prediction unit 2 ends the driving support process as it is.

  When the driving support processing according to the embodiment illustrated in FIG. 4 is summarized, when it is determined that the current position of the host vehicle C0 is in the vicinity of the front branch point in the front area set for the host vehicle C0 (FIG. 4 step S5; refer to YES) Even if it is determined that the turn signal W has been issued in the other vehicle Cn (see step S3 in FIG. 4; YES), the support unit 3 does not perform the corresponding merge guidance or the like. On the other hand, when it is determined that the turn signal W is being emitted from the vehicle Cn on the connecting road that flows in front (see step S6 in FIG. 4; YES), the support unit 3 executes necessary guidance processing ( (See step S10 in FIG. 4).

  On the other hand, even when there is no connecting road flowing in front (step S6 in FIG. 4; refer to NO), when it is determined that the turn signal W is emitted from the vehicle Cn existing on the road before the junction (step S7 in FIG. 4). ; Refer to YES), the support unit 3 executes necessary guidance processing (see step S10 in FIG. 4). On the other hand, when it is determined that there is no connecting road flowing forward, and it is determined that the turn signal W is being emitted from the vehicle Cn existing on the road that is not in front of the junction (front) (step in FIG. 4). S7; refer to NO), the support unit 3 does not perform the corresponding merge guidance or the like.

  Further, when there is no intersection CR or branch point ahead, and it is determined that the turn signal W has been issued in the nearby vehicle Cn (see step S4 in FIG. 4; NO), the support unit 3 falls. If there is an object or lane restriction, guidance processing to that effect is executed (see step S9 in FIG. 4).

  As described above, according to the operation of the inter-vehicle communication system CS according to the embodiment, it is based on the winker data and the current position data (hereinafter simply referred to as “winker data etc.”) acquired from the other vehicle Cn. Thus, the situation of the front area of the host vehicle C0 is predicted, and necessary guidance processing is performed based on the situation (see step S9 and step S10 in FIG. 4). Therefore, the winker obtained from the other vehicle Cn existing in the front area. Since the guidance process is performed based on the situation of the front area predicted using data or the like, the vehicle C0 can travel with a margin by predicting the situation ahead in some degree in advance.

  In addition, since winker data and the like are obtained for each count area A along the traveling direction of the host vehicle C0 and the front situation is predicted, the front situation can be predicted in more detail for each count area A.

  Furthermore, when it is determined that guidance processing for the predicted situation is necessary, the guidance processing is performed for the driver of the host vehicle C0 and the like, and thus the driver caused by unnecessary guidance processing being performed. It is possible to guide the predicted situation ahead while reducing the troublesomeness of the above.

  Furthermore, the number of other vehicles Cn flowing into a point ahead in the traveling direction is calculated based on the blinker data acquired from the other vehicles Cn ahead in the traveling direction, and the calculated number and each vehicle Cn Since the forward situation is predicted based on the data, necessary guidance processing can be performed in advance for the forward point where the vehicle flows.

  In addition, since it is predicted whether or not there is a need to change the lane ahead of the traveling direction based on the blinker data or the like, the driver or the like can recognize the necessity of changing the lane in advance.

  In the embodiment described above, the front area according to the embodiment may be narrowed down to an area that can be traced from the current position on the road on which the vehicle C0 is traveling.

  Further, the hazard data may be received from the other vehicle Cn in addition to the blinker data, and thereby the guidance process may be performed for a traffic jam existing in front of the host vehicle C0. In this case, for example, whether there is only one vehicle Cn that has received the hazard data or whether the hazard data has been received from a large number of vehicles Cn, is it a traffic jam (hazard data has been received from a large number of vehicles Cn) Or if accidents are accidentally used due to other reasons such as failure (when hazard data is received from only one vehicle Cn), and guide processing is performed according to the determination result. What is necessary is just to comprise.

  Further, whether the guidance process using voice (when close) or the guidance process using alarm sound (when far) is used depending on whether the distance to the forward vehicle Cn to be changed is close or far. ), Can be configured to be switched.

  Further, in the above-described embodiments, the case where the present application is applied to the inter-vehicle communication system CS using the inter-vehicle communication has been described, but other than 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). In this case, the terminal devices SS exchange data while identifying each other using the transmission source identification data and the like.

  Further, the map data or the like recorded in the recording unit 11 according to the embodiment is not recorded in the recording unit 11 but is acquired whenever necessary via a network such as the Internet. Also good.

  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.
