Description

[Technical Field]

[0001] The present invention relates to an information communication device, an information communication system, an information communication method, and a program. [Background technology]

[0002] In recent years, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications have become widespread, and various types of data are now being exchanged using V2X (Vehicle to Everything) communications technology. However, LTE-V2X PC5 communications cannot handle large-volume data transmissions such as video information. Furthermore, while large-volume data transmissions are possible using Uu communications such as the 5th generation mobile communications system (5G), communication is not possible unless information to identify the other vehicle, such as connection destination information, is known.

[0003] Patent Document 1 discloses that a management device transmits information to an on-board device of a vehicle regarding a section where congestion occurs and location information, network addresses, etc. of on-board devices located within the section where congestion occurs. Then, the on-board device of the vehicle selects candidate cameras to be candidates for camera video distribution based on the location information acquired from the management device.

[0004] Patent document 2 also discloses that, from among a plurality of vehicles, a vehicle that is currently located near the location where the user wishes to take a photograph, or a vehicle whose planned driving route overlaps with the location where the user wishes to take a photograph, is selected. [Prior art documents] [Patent documents]

[0006] As described above, in order to perform large-volume data communication using Uu communication such as 5G, information for identifying the other vehicle (on-board device) is required. In Patent Document 1, information on a section where congestion occurs and location information, network address, etc. of on-board devices located within the section where congestion occurs can be transmitted to the on-board device of the vehicle, but there is a possibility that an on-board device of a vehicle that meets the desired conditions cannot be identified.

[0007] In addition, in Patent Document 2, it is possible to select from multiple vehicles a vehicle that is currently located near the location where the user wishes to take a photo, but as with Patent Document 1, there is a possibility that it will not be possible to identify the on-board device of a vehicle that meets the desired conditions.

[0008] One aspect of the present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a technology that makes it possible to identify a vehicle that meets desired conditions and communicate with it. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Exemplary Embodiment 1 A first exemplary embodiment of the present invention will be described in detail with reference to the drawings. This exemplary embodiment is a basic form of the exemplary embodiments described below. Note that the drawing reference symbols added to this overview are added to each element for convenience as an example to facilitate understanding, and are not intended to limit the present invention to the illustrated form. Furthermore, connection lines between blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional lines. Unidirectional arrows are used to schematically indicate the flow of main signals (data) and do not exclude bidirectionality. Furthermore, the connection points of inputs and outputs of each block in the drawings may be configured to include ports or interfaces, but these configurations are not shown in the drawings.

[0016] <Information communication device 1 according to exemplary embodiment 1> 1 is a diagram showing the configuration of an information communication device 1 according to a first exemplary embodiment of the present invention, together with an exemplary vehicle and a server device. The information communication device 1 is mounted on each of a plurality of vehicles including a target vehicle. Here, the target vehicle refers to all vehicles within a V2X service area that are equipped with the information communication device 1. As shown in FIG. 1, the information communication device 1 according to this exemplary embodiment includes a receiving means 11, a determining means 12, and a transmitting means 13.

[0017] The first vehicle 31 is a vehicle that wishes to acquire predetermined information possessed by a second vehicle from the second vehicle, and transmits a communication request message specifying first identification information that identifies the second vehicle. For example, the first vehicle 31 transmits the communication request message to all vehicles within the V2X service area using C-V2X broadcast communication.

[0018] Both LTE C-V2X (LTE V2X) and 5G C-V2X (NR V2X) include two communication methods: direct communication (PC5 communication) and indirect communication (Uu communication). Uu communication is a method of communication via a base station, and is the same type of communication used by ordinary smartphones. Uu communication is a unicast type of communication, and is sometimes called V2N (Vehicle to Network) communication.

[0019] PC5 communication is a method of direct communication between vehicles or between roads and vehicles without going through a base station, and is also called V2V communication or V2I communication. PC5 communication is generally a broadcast type of communication, and is not suitable for large-volume communication due to limitations in bandwidth and wireless protocol specifications.

[0020] One of the aims of this invention is to acquire the Uu communication address of the communication partner using PC5 broadcast communication and perform large-volume communication by Uu communication using the acquired communication address. Hereinafter, unless otherwise specified, when simply written "C-V2X", it refers to PC5 communication.

[0021] Instead of PC5 communication, DSRC (Dedicated Short Range Communications), a wireless LAN-based vehicle-to-vehicle communication technology, may be used. DSRC is also a broadcast type of communication, and for example, specific information is transmitted via DSRC broadcast to obtain communication address information for LTE / 5G Uu communication from the target vehicle.

[0022] Furthermore, when server device 40 desires to acquire, from a second vehicle, predetermined information possessed by the second vehicle, server device 40 transmits a communication request message designating first identification information for identifying the second vehicle. For example, server device 40 transmits the communication request message to all vehicles within the V2X service area using C-V2X broadcast communication.

[0023] The receiving means 11 receives, using wireless communication, a communication request message that specifies first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40. For example, the receiving means 11 receives the communication request message from the first vehicle 31 or the server device 40 using C-V2X.

[0024] In C-V2X PC5 communication, communication is basically carried out by broadcast communication, so when communicating with a specific vehicle or server device, broadcast communication is carried out specifying the specific vehicle or server device.

[0025] Data exchanged using V2X communication technology includes road traffic information, data related to vehicle behavior, data related to platooning and following driving, data related to autonomous driving, etc. In this exemplary embodiment, among these data, data related to vehicle behavior, in particular information on the vehicle's driving area, location information, driving speed, driving distance, driving characteristics such as acceleration / deceleration and steering, and vehicle status, etc., can be used.

[0026] The first identification information is information for identifying the second vehicle that will be the communication partner of the first vehicle 31 or the server device 40, and is, for example, characteristic information indicating the characteristics of the second vehicle, location information of the second vehicle, etc.

[0027] 2 is a diagram illustrating an example of first identification information for identifying a second vehicle. In FIG. 2, the first vehicle corresponds to vehicle A31. At least vehicles B33 and C34 are equipped with the information communication device 1 according to this exemplary embodiment, and the second vehicle corresponds to vehicle B33 or vehicle C34.

[0028] A truck 32 is present ahead of a first vehicle, car A31, in the direction of travel, and the driver of car A31 is unable to see further ahead of the truck 32. If the driver of car A31 desires an image of the area ahead of the truck 32, the first identification information is characteristic information, location information, etc. indicating the characteristics of car B33 or car C34 that has an image of the area ahead of the truck 32. The driver of car A31 uses an in-vehicle terminal to transmit a communication request message specifying the first identification information via a communication network N using broadcast communication. The communication network N is, for example, V2X, a 5G (fifth generation mobile communication system) core network defined by 3GPP (3rd Generation Mobile Partnership Project), a 4G (fourth generation mobile communication system) core network, etc.

[0029] The determination means 12 determines whether the target vehicle is a second vehicle that is the target of the communication request by referring to the first identification information. For example, the information communication device 1 has characteristic information of the vehicle (target vehicle) on which the information communication device 1 is installed, and determines whether the target vehicle is a second vehicle depending on whether the first identification information matches the characteristic information of the target vehicle. For example, if the first identification information is the body color of the vehicle, it determines whether the target vehicle is a second vehicle depending on whether it matches the characteristic information (body color) of the target vehicle.

[0030] When the target vehicle is a second vehicle, the transmission means 13 transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. One example of the predetermined information possessed by the target vehicle is communication connection information of the information communication device 1 mounted on the target vehicle. The communication connection information may be, for example, an IP address or the like, and is not limited to this as long as it is information that can identify the communication partner.

[0031] The predetermined information possessed by the specific vehicle may be transmitted by unicast communication or broadcast communication by the transmitting means 13. For example, if the source IP address of the communication request message is included in the header portion or data portion of the communication request message, the information may be transmitted to the IP address by unicast communication.

[0032] Furthermore, when the identifier of the communication request message is included in the header or data portion of the communication request message, it may be transmitted by broadcast communication together with information indicating that it is a response to the identifier.

[0033] If the communication request message includes communication connection information of the first vehicle 31, the information communication device 1 can communicate with the first vehicle 31 using a communication network such as 5G or 4G.

[0034] Furthermore, if the predetermined information held by the target vehicle is an image captured by a camera mounted on the target vehicle, the information communication device 1 can communicate large amounts of data such as video information with the first vehicle 31 using a communication network such as 5G or 4G. Therefore, the car A31 can acquire an image of the area ahead of the truck 32.

[0035] <Advantages of the information communication device 1 according to the first exemplary embodiment> As described above, according to the information communication device 1 of this exemplary embodiment, the determination means 12 refers to the first identification information to determine whether the target vehicle is a second vehicle that is the target of a communication request. If the target vehicle is a second vehicle, the transmission means 13 transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. Therefore, by the first vehicle 31 or the server device 40 transmitting a communication request message specifying the first identification information that identifies the second vehicle, it is possible to identify a vehicle that meets the desired conditions and communicate with it.

[0036] <Flow of information communication method by information communication device 1> The flow of the information communication method executed by the information communication device 1 configured as above will be described with reference to Fig. 3. Fig. 3 is a flow diagram showing the flow of the information communication method of the information communication device 1 according to the first exemplary embodiment of the present invention. As shown in Fig. 3, the information communication method includes steps S1 to S3.

[0037] First, the receiving means 11 receives, by wireless communication, a communication request message that specifies first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40 (S1). For example, the receiving means 11 receives the communication request message from the first vehicle 31 or the server device 40 by using C-V2X.

[0038] Next, the determination means 12 refers to the first identification information to determine whether the target vehicle is a second vehicle that is the target of the communication request (S2). For example, the information communication device 1 has characteristic information of the vehicle (target vehicle) in which the information communication device 1 is installed, and determines whether the first identification information is the second vehicle based on whether it matches the characteristic information of the target vehicle. If the target vehicle is not the second vehicle (S2, No), the process ends.

[0039] Furthermore, if the target vehicle is a second vehicle (S2, Yes), the transmission means 13 transmits (S3) predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. The predetermined information possessed by the target vehicle is, for example, communication connection information of the information communication device 1 mounted on the target vehicle.

[0040] <Effects of the information communication method of the information communication device 1 according to the exemplary embodiment 1> As described above, according to the information communication method of the information communication device 1 according to this exemplary embodiment, the first identification information is referenced to determine whether the target vehicle is a second vehicle that is the target of a communication request, and if the target vehicle is the second vehicle, predetermined information possessed by the target vehicle is transmitted to the first vehicle 31 or the server device 40. Therefore, by the first vehicle 31 or the server device 40 transmitting a communication request message specifying the first identification information that identifies the second vehicle, it is possible to identify a vehicle that meets the desired conditions and communicate with it.

[0041] <Configuration of Information Communication System 100> The configuration of an information communication system 100 according to this exemplary embodiment will be described with reference to Fig. 4. Fig. 4 is a block diagram showing the configuration of the information communication system 100 according to the first exemplary embodiment of the present invention. The information communication system 100 is an information communication system including an information communication device 1 mounted on a target vehicle, and as shown in Fig. 4, includes a first transmission means 21, a determination means 22, and a second transmission means 23.

[0042] The first transmitting means 21, the determining means 22, and the second transmitting means 23 are configured to be able to communicate with each other via a network N. Here, the specific configuration of the network N does not limit the present exemplary embodiment, but examples include the above-mentioned V2X, 5G core network, 4G core network, etc.

[0043] The first transmitting means 21 is disposed, for example, in the above-mentioned first vehicle 31 or server device 40, and uses broadcast wireless communication to transmit a communication request message specifying first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or server device 40. The first vehicle 31 and server device 40 are a vehicle and device that wish to obtain predetermined information possessed by the second vehicle from the second vehicle, and transmit a communication request message specifying the first identification information that identifies the second vehicle.

[0044] The determination means 22 is, for example, disposed in the information communication device 1, and determines whether the target vehicle is a second vehicle that is the target of the communication request by referring to the first identification information. For example, the information communication device 1 has characteristic information of the vehicle (target vehicle) in which the information communication device 1 is installed, and determines whether the vehicle is the second vehicle based on whether the first identification information matches the characteristic information of the target vehicle.

[0045] The second transmission means 23 is disposed in, for example, the information communication device 1 described above, and when the target vehicle is a second vehicle, transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. The predetermined information possessed by the target vehicle is, for example, communication connection information of the information communication device 1 mounted on the target vehicle.

[0046] <Flow of information communication method by information communication system 100> The flow of the information communication method executed by the information communication system 100 configured as above will be described with reference to Fig. 5. Fig. 5 is a flow diagram showing the flow of the information communication method of the information communication system 100 according to the first exemplary embodiment of the present invention. As shown in Fig. 5, the information communication method includes steps S11 to S13.

[0047] First, the first transmission means 21 uses broadcast wireless communication to transmit a communication request message specifying first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40 (S11). For example, the first transmission means 21 uses C-V2X broadcast communication to transmit the communication request message to all vehicles within the V2X service area.

[0048] Next, the determination means 22 refers to the first identification information to determine whether the target vehicle is a second vehicle that is the target of the communication request (S12). For example, the information communication device 1 has characteristic information of the vehicle (target vehicle) in which the information communication device 1 is installed, and determines whether the first identification information matches the characteristic information of the target vehicle to determine whether the target vehicle is the second vehicle. If the target vehicle is not the second vehicle (S12, No), the process ends.

[0049] Furthermore, if the target vehicle is a second vehicle (S12, Yes), the second transmission means 23 transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40 (S13). The predetermined information possessed by the target vehicle is, for example, communication connection information of the information communication device 1 mounted on the target vehicle.

[0050] <Advantages of the information communication system 100 according to the first exemplary embodiment> As described above, according to the information communication system 100 of this exemplary embodiment, the determination means 22 refers to the first identification information to determine whether the target vehicle is a second vehicle that is the target of a communication request. If the target vehicle is a second vehicle, the second transmission means 23 transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. Therefore, by the first transmission means 21 transmitting a communication request message specifying the first identification information that identifies the second vehicle, it is possible to identify a vehicle that meets the desired conditions and communicate with it.

[0051] Exemplary Embodiment 2 A second exemplary embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same functions as those described in the first exemplary embodiment are given the same reference numerals, and their description will be omitted as appropriate.

[0052] <Information communication device 1A according to exemplary embodiment 2> 6 is a diagram showing the configuration of an information communication device 1A according to a second exemplary embodiment of the present invention. As shown in FIG. 6, the information communication device 1A according to this exemplary embodiment includes a receiving means 11, a determining means 12, a transmitting means 13, a receiving means 14, and a storage means 15.

[0053] The receiving means 11 receives, using wireless communication, a communication request message that specifies first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40. For example, the receiving means 11 receives the communication request message from the first vehicle 31 or the server device 40 using C-V2X.

[0054] The first identification information includes at least one of the license plate information, the vehicle model, and the body color of the second vehicle.

[0055] In the storage means 15, at least one of the license plate information, the vehicle model, and the body color is registered in advance as characteristic information of the target vehicle.

[0056] The determination means 12 determines whether the target vehicle is a second vehicle based on whether at least one of the first identification information matches pre-registered information. For example, if the first identification information is the body color of the vehicle, the determination means 12 determines whether the target vehicle is a second vehicle based on whether it matches characteristic information (body color) of the target vehicle pre-registered in the storage means 15.

[0057] Furthermore, if the first identification information is the license plate information of the target vehicle, the determination means 12 determines whether the target vehicle is a second vehicle based on whether part or all of the license plate information of the target vehicle pre-registered in the storage means 15 matches.

[0058] Furthermore, if the first identification information is location information of a second vehicle, the determination means 12 determines whether the target vehicle is the second vehicle based on whether the location information of the target vehicle matches the location information of the second vehicle. For example, the information communication device 1 can acquire location information of vehicles present within a V2X service area using V2X, and thus can acquire the location information of the target vehicle. The determination means 12 determines whether the target vehicle is the second vehicle based on whether the acquired location information of the target vehicle matches the location information of the second vehicle, which is the first identification information. Note that if the distance between the location indicated by one piece of location information and the location indicated by the other piece of location information is equal to or less than a predetermined distance, the location information is determined to match.

[0059] As described above, the match of the position information is not limited to a perfect match. For example, if the difference between the position information of the target vehicle and the position information of the second vehicle is equal to or less than a predetermined value, the position information may be considered to match. This predetermined value may be determined based on the speed of the second vehicle. Specifically, the faster the speed of the second vehicle, the larger the predetermined value may be set. Furthermore, the direction of movement may also be taken into consideration. This is to determine whether the direction of the error matches the vehicle's traveling direction.

[0060] The accepting unit 14 accepts a selection by the user. The accepting unit 14 is configured by an input device such as a keyboard, and accepts from the user whether or not to respond to the communication request message.

[0061] The transmitting means 13 transmits predetermined information possessed by the target vehicle when the determining means 12 determines that the target vehicle is a second vehicle and when the user selects to respond to the communication request message by the receiving means 14. Furthermore, even when the determining means 12 determines that the target vehicle is a second vehicle, the transmitting means 13 does not transmit the predetermined information possessed by the target vehicle when the user selects not to respond to the communication request message by the receiving means 14.

[0062] In the above description, the transmitting means 13 performs the determination process of whether or not to transmit the specified information according to the above conditions, but for example, the determination process may be performed by the determining means 12.

[0063] The predetermined information possessed by the target vehicle is, for example, communication connection information of the target vehicle in wireless communication. When the on-board terminal of vehicle A31 receives the communication connection information from vehicle B33 or vehicle C34, which is the target vehicle, it becomes possible to perform large-volume data communication of video information and the like with vehicle B33 or vehicle C34 using a communication network such as 5G or 4G. Therefore, vehicle A31 can acquire video of the area ahead of truck 32.

[0064] Furthermore, the predetermined information possessed by the target vehicle may be sensing information acquired by a sensing device 50 mounted on the target vehicle. The sensing device 50 is, for example, a visible light camera, an infrared sensor, an ultrasonic sensor, a LiDAR (Light Detection and Ranging), a millimeter wave radar, etc. If the sensing device 50 is an imaging device such as a visible light camera, the transmission means 13 transmits image information captured by the imaging device to the first vehicle 31.

[0065] <Advantages of the information communication device 1A according to the second exemplary embodiment> As described above, according to the information communication device 1A of this exemplary embodiment, the determination means 12 determines whether the target vehicle is a second vehicle based on whether at least one of the first identification information (the license plate information, vehicle type, and body color of the second vehicle) matches pre-registered information. Therefore, by the first vehicle 31 transmitting a communication request message specifying the first identification information that represents the characteristics of the second vehicle, it is possible to identify a vehicle that meets the desired conditions and communicate with it.

[0066] Furthermore, the determination means 12 determines whether the target vehicle is the second vehicle based on whether the location information of the target vehicle matches the location information of the second vehicle. Therefore, when the first vehicle 31 transmits a communication request message specifying the location information of the second vehicle, it is possible to identify a vehicle that meets the desired conditions and communicate with it.

[0067] Furthermore, even if the target vehicle is a second vehicle, if the user selects not to respond to the communication request message, the transmission means 13 does not transmit the predetermined information possessed by the target vehicle. Therefore, the user of the target vehicle can decide whether or not to respond to the communication request message.

[0068] Furthermore, since the predetermined information held by the target vehicle is the communication connection information of the target vehicle in wireless communication, the first vehicle 31 can perform large-volume data communication with the target vehicle.

[0069] Furthermore, since the specified information possessed by the target vehicle is sensing information acquired by the sensing device 50 mounted on the target vehicle, even if there is a vehicle in front of the first vehicle 31 that blocks the view, information regarding the area in front of the vehicle that blocks the view can be acquired.

[0070] [Modification of Exemplary Embodiment 2] A modified example of the second exemplary embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same functions as those described in the second exemplary embodiment will be given the same reference numerals, and their description will be omitted as appropriate.

[0071] In the second exemplary embodiment, the receiving means 11 is configured to receive a communication request message specifying first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40. In this modified example, the receiving means 11 is configured to receive a communication request message that specifies first identification information and second identification information that identify a second vehicle that will be a communication partner of the first vehicle 31 or the server device 40. This modified example will be described using FIG. 6.

[0072] The communication request message further includes second identification information regarding the behavior of the second vehicle. The second identification information is information regarding the behavior of the vehicle, such as turning left, turning right, stopping, going straight, etc. For example, if the first identification information indicates that the body color is "red" and the second identification information indicates that the vehicle is "turning right," the information for identifying the second vehicle is "a red vehicle that turned right."

[0073] The information communication device 1A can acquire information about the behavior of the target vehicle by referring to the V2X information. For example, the information communication device 1A acquires blinking operation information of the target vehicle or operation information of the steering wheel, so that the determination means 12 can determine whether the target vehicle is turning right or left. Furthermore, the information communication device 1A acquires speed information of the target vehicle, so that the determination means 12 can determine whether the target vehicle is stopped.

[0074] Furthermore, the identification information may include lane information in which the second vehicle is traveling, such as the first travel lane, the second travel lane, or the passing lane. The lane information may be included in the first identification information or the second identification information. Furthermore, the lane information may be used as the third identification information, and the determination means 12 may determine whether the target vehicle is the second vehicle based on the first identification information, the second identification information, and the third identification information.

[0075] The determination means 12 combines the first identification information and the second identification information to determine whether the target vehicle is the second vehicle. For example, if the first identification information indicates that the body color is "red" and the second identification information indicates that the vehicle is "turning right," the determination means 12 first refers to the first identification information to determine whether the body color of the target vehicle is "red."

[0076] If the body color of the target vehicle is "red," the determination means 12 refers to the history of V2X information and determines whether the target vehicle has made a right turn within a predetermined time. Note that information regarding the behavior of the target vehicle is stored in the storage means 15, and the determination means 12 can refer to the history of the behavior of the target vehicle.

[0077] If the determination means 12 determines that the target vehicle is a "red vehicle that turned right" and the user selects to respond to the communication request message, the transmission means 13 transmits specified information possessed by the target vehicle to the first vehicle 31.

[0078] <Advantages of the Information Communication Device 1A According to the Modification of the Second Exemplary Embodiment> As described above, according to the information communication device 1A of this modified example, the determination means 12 combines the first specific information and the second specific information to determine whether the target vehicle is the second vehicle, so that a vehicle meeting the desired conditions can be specified in more detail.

[0079] Exemplary Embodiment 3 A third exemplary embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same functions as those described in the first exemplary embodiment are given the same reference numerals, and their description will be omitted as appropriate.

[0080] <Information and Communication System 100A According to Exemplary Embodiment 3> 7 is a diagram showing the configuration of an information communication system 100A according to a third exemplary embodiment of the present invention. As shown in FIG. 7, the information communication system 100A according to this exemplary embodiment includes an information communication device 1B, a server device 60, and a first vehicle 31.

[0081] The first vehicle 31 includes a first transmitting means 21. The information communication device 1B includes a receiving means 24, a determining means 22, and a second transmitting means 23. The server device 60 includes a receiving means 25, a storage means 26, and a third transmitting means 27. The first transmitting means 21, the receiving means 24 and 25, the determining means 22, the second transmitting means 23, and the third transmitting means 27 are configured to be able to communicate with each other via a network N, for example. Here, the specific configuration of the network N does not limit the present exemplary embodiment, but examples include the above-mentioned V2X, a 5G core network, a 4G core network, etc.

[0082] The first transmitting means 21 of the first vehicle 31 uses broadcast wireless communication to transmit a communication request message specifying first identification information that identifies a second vehicle with which the first vehicle 31 will communicate.

[0083] The receiving means 24 of the information communication device 1B receives, by wireless communication, a communication request message that specifies first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31. For example, the receiving means 11 receives the communication request message from the first vehicle 31 or the server device 60 by using C-V2X.

[0084] The determination means 22 determines whether the target vehicle is a second vehicle that is the target of the communication request by referring to the first identification information. For example, the information communication device 1 has characteristic information of the vehicle (target vehicle) in which the information communication device 1 is installed, and determines whether the first identification information is the second vehicle based on whether it matches the characteristic information of the target vehicle.

[0085] When the target vehicle is a second vehicle, the second transmission means 23 of the information communication device 1B transmits predetermined information possessed by the target vehicle to the first vehicle 31 or the server device 40. The predetermined information possessed by the target vehicle is, for example, communication connection information of the information communication device 1 mounted on the target vehicle.

[0086] The storage means 26 of the server device 60 stores the first identification information corresponding to each vehicle included in the vehicle group and the communication connection information of each vehicle in association with each other.

[0087] The receiving means 25 of the server device 60 receives a communication request message from the first vehicle 31, which designates the first identification information that identifies the second vehicle.

[0088] When the first specific information contained in the communication request message received by the receiving means 25 is stored in the memory means 26 of the server device 60, the third transmitting means 27 acquires communication connection information corresponding to the second vehicle from the memory means 26 and transmits the communication connection information to the first vehicle or the server device 40.

[0089] Furthermore, if the first specific information contained in the communication request message received by the receiving means 25 is not stored in the storage means 26, the third transmitting means 27 transfers the communication request message using broadcast wireless communication.

[0090] In this case, the receiving means 25 receives communication connection information corresponding to the second vehicle from the second vehicle, and the storage means 26 stores the communication connection information corresponding to the second vehicle in association with the first identification information that identifies the second vehicle.

[0091] <Flow of information communication method by information communication system 100A> The flow of the information communication method executed by the information communication system 100A configured as above will be described with reference to Fig. 8. Fig. 8 is a flow diagram showing the flow of the information communication method of the information communication system 100A according to the third exemplary embodiment of the present invention. As shown in Fig. 8, the information communication method includes steps S21 to S27.

[0092] First, the first transmission means 21 of the first vehicle 31 uses broadcast wireless communication to transmit a communication request message specifying first identification information that identifies a second vehicle that will be a communication partner of the first vehicle 31 (S21). For example, the first transmission means 21 transmits the communication request message using C-V2X broadcast communication.

[0093] Next, the determination means 22 of the information communication device 1B refers to the first identification information included in the communication request message received by the receiving means 24 and determines whether the target vehicle is a second vehicle that is the target of the communication request (S22). If the target vehicle is not the second vehicle (S22, No), the process ends. If the target vehicle is the second vehicle (S22, Yes), the second transmission means 23 transmits communication connection information of the target vehicle to the first vehicle 31 and the server device 60 (S23).

[0094] On the other hand, when the receiving means 25 of the server device 60 receives a communication request message from the first vehicle 31 (S24), it determines whether or not the first specification information included in the communication request message is stored in the storage means 26 (S25). If the first specification information included in the communication request message is stored in the storage means 26 (S25, Yes), the third sending means 27 acquires communication connection information corresponding to the second vehicle from the storage means 26 and sends the communication connection information to the first vehicle (S27).

[0095] Furthermore, if the first identification information included in the communication request message is not stored in the storage means 26 (S25, No), the storage means 26 stores the communication connection information corresponding to the second vehicle in association with the first identification information that identifies the second vehicle (S26).

[0096] <Advantages of the information communication system 100A according to the third exemplary embodiment> As described above, according to the information communication system 100A according to this exemplary embodiment, when the first identification information corresponding to the second vehicle is stored in the storage means 26, the third transmission means 27 acquires the communication connection information corresponding to the second vehicle from the storage means 26 and transmits the communication connection information to the first vehicle 31 or the server device 40. Therefore, the second transmission means 23 of the information communication device 1B does not need to transmit the communication connection information to the first vehicle 31 or the server device 40, and the processing time can be shortened.

[0097] [Software implementation example] Some or all of the functions of the information communication devices 1, 1A, 1B and the information communication systems 100, 100A may be realized by hardware such as an integrated circuit (IC chip), or may be realized by software.

[0098] In the latter case, the information communication devices 1, 1A, and 1B and the information communication systems 100 and 100A are realized, for example, by a computer that executes instructions of a program, which is software that realizes each function. An example of such a computer (hereinafter referred to as computer C) is shown in FIG. 9. The computer C includes at least one processor C1 and at least one memory C2. The memory C2 stores a program P for operating the computer C as the information communication devices 1, 1A, and 1B and the information communication systems 100 and 100A. In the computer C, the processor C1 reads and executes the program P from the memory C2, thereby realizing each function of the information communication devices 1, 1A, and 1B and the information communication systems 100 and 100A.

[0099] The processor C1 may be, for example, a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), a micro processing unit (MPU), a floating point number processing unit (FPU), a physics processing unit (PPU), a microcontroller, or a combination thereof. The memory C2 may be, for example, a flash memory, a hard disk drive (HDD), a solid state drive (SSD), or a combination thereof.

[0100] The computer C may further include a RAM for expanding the program P during execution and for temporarily storing various data. The computer C may also include a communication interface for transmitting and receiving data to and from other devices. The computer C may also include an input / output interface for connecting input / output devices such as a keyboard, mouse, display, and printer.

[0101] Furthermore, the program P can be recorded on a non-transitory tangible recording medium M that can be read by the computer C. Such a recording medium M can be, for example, a tape, a disk, a card, a semiconductor memory, or a programmable logic circuit. The computer C can acquire the program P via such a recording medium M. The program P can also be transmitted via a transmission medium. Such a transmission medium can be, for example, a communication network or broadcast waves. The computer C can also acquire the program P via such a transmission medium.
