An information control system 1 according to the first embodiment is mounted on a vehicle. The information control system 1 includes an inter-vehicle communication device 2, a distance sensor 3, a display device 4, and an information control device 10. The information control system 1 may be configured to independently include the inter-vehicle communication device 2, the distance sensor 3 and the display device 4, or the existing inter-vehicle communication device 2 mounted on the vehicle, the distance sensor 3, and The display 4 may be used.
Hereinafter, the target vehicle on which the information control system 1 is mounted will be referred to as the "own vehicle", and other vehicles located around the target vehicle will be referred to as the "surrounding vehicle". The user who uses the information control system 1 may be any occupant of the host vehicle, but here a driver is assumed.

  The inter-vehicle communication device 2 mounted on the host vehicle performs inter-vehicle communication with an inter-vehicle communication device mounted on a nearby vehicle to transmit and receive information. The inter-vehicle communication device 2 according to the first embodiment receives position information indicating the position of the nearby vehicle from a nearby vehicle capable of inter-vehicle communication located around the host vehicle.

  The distance sensor 3 measures the distance between the host vehicle and the surrounding vehicle, detects the position of the surrounding vehicle based on the measurement result, and outputs it as position information. The distance sensor 3 detects the positions of surrounding vehicles located in all directions of the host vehicle without distinction between communicable vehicles and non-communicable vehicles. The distance sensor 3 is, for example, an ultrasonic sensor, a radio wave sensor, or a stereo camera. In addition, the distance sensor 3 uses a camera for imaging the surroundings of the host vehicle and a recognition device for recognizing an object on an image captured by the camera, and the object detected by the ultrasonic sensor or the radio wave sensor is a vehicle or a walk. It may be recognized whether the person is a bicycle, a bicycle, a motorcycle or the like.

  The display device 4 is a display that displays an image. The display device 4 is installed at a position where a driver can view, such as a dashboard.

  The information control device 10 includes a first vehicle position acquisition unit 11, a second vehicle position acquisition unit 12, a communication availability determination unit 13, and a drawing unit 14.

  FIG. 2 is a flow chart showing an operation example of the information control system 1 according to the first embodiment of the present invention. The information control system 1 repeats the process shown in the flowchart of FIG.

  In step ST11, the first vehicle position acquisition unit 11 acquires, from the inter-vehicle communication device 2, the position information of a nearby vehicle located around the host vehicle and capable of inter-vehicle communication. The first vehicle position acquisition unit 11 outputs the acquired position information to the communication determination unit 13.

  In step ST12, the second vehicle position acquisition unit 12 acquires, from the distance sensor 3, position information of a surrounding vehicle located around the host vehicle. The second vehicle position acquisition unit 12 outputs the acquired position information to the communication determination unit 13.

  In step ST13, based on the difference between the position information received from the first vehicle position acquisition unit 11 and the position information received from the second vehicle position acquisition unit 12, the communication possibility determination unit 13 positions around the host vehicle. Vehicle is determined as a communicable vehicle and a communicable vehicle.

Here, the process of step ST13 will be described in detail with reference to FIG.
FIG. 3 is a flowchart showing the details of step ST13 of FIG.
The communication possibility determination unit 13 repeats the processes of steps ST131 to ST135 as many as the number A (A00) of the peripheral vehicles that have acquired the position information from the inter-vehicle communication device 2 in step ST11.
In the case of “A ≧ 1”, in step ST132, the communication possibility determination unit 13 determines that one of the one or more peripheral vehicles for which the position information has been acquired from the inter-vehicle communication device 2 is a communicable vehicle. , Register the vehicle information of the communicable vehicle. The vehicle information includes an ID assigned to the communicable vehicle and position information of the communicable vehicle. The ID is an arbitrary value that is different for each vehicle. Here, it is assumed that "ID: 001" is assigned to the communicable vehicle. The position information is position information acquired from the inter-vehicle communication device 2.

In step ST133, the communication possibility determination unit 13 determines that the position of the communicable vehicle to which “ID: 001” is assigned is any of 0 or more nearby vehicles for which the position information could be acquired from the distance sensor 3 in step ST12. It is determined whether or not it matches the position of the surrounding vehicle.
Communication permission determination unit 13 determines that the position of the communicable vehicle to which “ID: 001” is assigned is any one of 0 or more nearby vehicles for which the position information can be acquired from distance sensor 3 in step ST12. If the position matches (step ST133 "YES"), the process proceeds to step ST134.
On the other hand, the communication possibility determination unit 13 determines that any nearby vehicles among 0 or more nearby vehicles for which the position of the communicable vehicle to which “ID: 001” is assigned can obtain position information from the distance sensor 3 in step ST12. (Step ST133 "NO"), step ST134 is skipped.

  In step ST134, the communication possibility determination unit 13 matches the position of the communicable vehicle to which “ID: 001” is assigned among the 0 or more peripheral vehicles for which the position information can be acquired from the distance sensor 3 in step ST12. Delete the location information of surrounding vehicles.

As a result of repeating the processing of steps ST131 to ST135, the difference between the peripheral vehicle whose position information has been acquired from the inter-vehicle communication device 2 and the peripheral vehicle whose position information has been acquired from the distance sensor 3 is determined. That is, as a result of repeating the processing of steps ST131 to ST135, among the 0 or more peripheral vehicles for which the position information can be acquired from the distance sensor 3, the peripheral vehicles for which the position information can be acquired from the inter-vehicle communication device 2 are excluded. There remain peripheral vehicles for which the position information could not be acquired from the inter-vehicle communication device 2. Let B (B ≧ 0) be the number of remaining surrounding vehicles. The remaining surrounding vehicles are vehicles that can not communicate.
Further, as a result of repeating the processing of steps ST131 to ST135, vehicle information of each communicable vehicle located around the host vehicle is registered.

Subsequently, the communication possibility determination unit 13 repeats the processing of steps ST136 to ST138 for the number B of the remaining surrounding vehicles.
In the case of "B ≧ 1", in step ST137, the communication possibility determination unit 13 can not acquire the position information from the inter-vehicle communication device 2 among the one or more peripheral vehicles for which the position information has been acquired from the distance sensor 3 One of the surrounding vehicles is determined to be a non-communicable vehicle, and vehicle information of the non-communicable vehicle is registered. The vehicle information includes an ID assigned to the incommunicable vehicle and position information of the incommunicable vehicle. This position information is position information acquired from the distance sensor 3.

As a result of repeating the processing of steps ST136 to ST138, the vehicle information of each incommunicable vehicle located around the host vehicle is registered.
Finally, the communication possibility determination unit 13 outputs the vehicle information of the communicable vehicle and the vehicle information of the communicable information to the drawing unit 14.

  In step ST14 of FIG. 2, the drawing unit 14 displays the peripheral vehicles located around the host vehicle based on the vehicle information of the communicable vehicle received from the communication possibility determination unit 13 and the vehicle information of the communication impossible information. For drawing images. The drawing unit 14 outputs the drawn display image to the display device 4 for display. The drawing unit 14 may be included in the information control device 10 or may be included in the display device 4. When the display device 4 includes the drawing unit 14, the communication possibility determination unit 13 outputs the vehicle information of the communicable vehicle and the vehicle information of the communicable information to the display device 4.

  FIG. 4 is a diagram showing an example of screen display in the first embodiment of the present invention. On the screen of the display device 4, the host vehicle on the map, the communicable vehicle, and the communicable vehicle are displayed so that the positional relationship can be understood. Further, since the display mode differs between the communicable vehicle and the non-communicable vehicle, the driver can distinguish and recognize the communicable vehicle and the non-communicable vehicle located around the own vehicle. In addition, in order to distinguish a communicable vehicle and a non-communicable vehicle, the display mode may be different as long as the display color is different. Further, in this example, the IDs of the communicable vehicles and the communicable vehicles registered by the communication determination unit 13 are displayed.

  As described above, the information control device 10 according to the first embodiment includes the first vehicle position acquisition unit 11, the second vehicle position acquisition unit 12, and the communication availability determination unit 13. The first vehicle position acquisition unit 11 acquires, from the inter-vehicle communication device 2, position information of a nearby vehicle located around the target vehicle and capable of inter-vehicle communication. The second vehicle position acquisition unit 12 acquires, from the distance sensor 3, position information of a surrounding vehicle located around the target vehicle, which is detected by the distance sensor 3. Based on the difference between the position information acquired by the first vehicle position acquisition unit 11 and the position information acquired by the second vehicle position acquisition unit 12, the communication availability determination unit 13 is a peripheral vehicle located around the target vehicle Are determined as a communicable vehicle capable of inter-vehicle communication and a communicable vehicle not capable of inter-vehicle communication. Thereby, the information control device 10 can discriminate between the communicable vehicle and the non-communicable vehicle located around the target vehicle.

  Further, the information control system 1 according to the first embodiment includes an information control device 10 and a display device 4. The display device 4 distinguishes and displays the surrounding vehicles determined to be capable of inter-vehicle communication by the information control device 10 and the surrounding vehicles determined to be impossible. Thereby, the determination result can be provided to the occupant of the target vehicle.

Second Embodiment
The information control system 1 according to the second embodiment of the present invention transmits the intention or the like of the driver of the host vehicle to surrounding vehicles located around the host vehicle. The information control system 1 transmits information indicating the driver's intention or the like by inter-vehicle communication if the surrounding vehicle is a communicable vehicle, and emits light if the communicable vehicle.

  FIG. 5 is a block diagram showing an example of the configuration of an information control system 1 according to Embodiment 2 of the present invention. The information control system 1 according to the second embodiment is the same as the information control system 1 according to the first embodiment shown in FIG. 1 except that the transmission information determination unit 21, the irradiation position determination unit 22, the irradiation control unit 23, and the input device 24. And the light irradiation device 25 is added. Further, in the second embodiment, the vehicle information of the communicable vehicle and the vehicle information of the non-communicable vehicle are output from the communication possibility determination unit 13 to the irradiation position determination unit 22. Parts in FIG. 5 that are the same as or correspond to those in FIG. The information control system 1 may be configured to independently include the input device 24 and the light irradiation device 25, or may be configured to use the existing input device 24 and the light irradiation device 25 mounted on the vehicle. It is also good.

  The input device 24 receives an operation input of the driver of the host vehicle, and outputs information indicating the received content to the transmission information determination unit 21. The input device 24 is a touch panel, a button installed on a handle, a remote controller, a voice recognition device, or the like. Also, for example, the display of the display device 4 and the touch panel of the input device 24 may be integrated.

The light irradiation device 25 irradiates light to at least one of the bonnet of the host vehicle, the rear glass, and the road surface around the host vehicle. Although it is desirable that the light irradiation device 25 for irradiating light to the road surface can irradiate light to the road surface in all directions of the host vehicle, the present invention is not limited thereto. Just do it. The light irradiation device 25 is a laser device mounted on the host vehicle, a light emitting diode (LED) light irradiation device, a projector device, or the like. In addition, the brightness of the light which the light irradiation apparatus 25 irradiates is taken as the brightness which the driver | operator of a surrounding vehicle can visually recognize regardless of the surrounding brightness.
The distance from the host vehicle to the irradiation position farthest from the host vehicle when the light irradiation device 25 applies light to the road surface around the host vehicle is referred to as “irradiation limit distance”.

  FIG. 6 is a flowchart showing an operation example of the information control system 1 according to the second embodiment of the present invention. Steps ST11 to ST14 in FIG. 6 are the same processing as steps ST11 to ST14 in FIG.

  In step ST21, the input device 24 receives, by the operation of the driver of the own vehicle, the peripheral vehicles to which the driver wishes to transmit the intention and the information to be transmitted. The surrounding vehicles to which transmission is to be performed are called "transmission destination vehicles", and the information to be transmitted is called "transmission information". The input device 24 inputs the transmission destination vehicle and the transmission information to the transmission information determination unit 21. The transmission information determination unit 21 receives the transmission destination vehicle and the transmission information from the input device 24, and outputs the transmission destination determination unit 21 to the irradiation position determination unit 22.

Here, an example in which the driver inputs the transmission destination vehicle and the transmission information will be described using FIGS. 4 and 7. FIG. 7 is a diagram showing an example of screen display in the second embodiment of the present invention.
In this example, it is assumed that a touch panel as the input device 24 is integrated with a display as the display device 4. The display device 4 displays a screen as shown in FIG. 4, and the driver selects a transmission destination vehicle from among the peripheral vehicles of “ID: 001” to “ID: 005”. For example, it is assumed that the driver selects a nearby vehicle of “ID: 005” located behind the host vehicle as a transmission destination vehicle. In that case, the transmission information determination unit 21 instructs the drawing unit 14 to display the screen of the transmission information candidate list 201 to be transmitted to the rear vehicle as shown in FIG. 7. The driver selects a desired transmission information icon 202 from the transmission information candidate list 201. The driver registers the transmission information to be displayed as the transmission information icon 202 in advance in the transmission information determination unit 21 when not in operation, so that the transmission information icon 202 is selected from the transmission information candidate list 201. Transmission information can be input by a simple operation of selecting. Note that the driver can use different transmission information depending on the position of the transmission destination vehicle with respect to the host vehicle, such as a candidate list of transmission information when the transmission destination vehicle is a backward vehicle and a candidate list of transmission information when it is a forward vehicle. A candidate list may be registered. In addition, when the input device 24 includes a voice recognition device, the driver can input the transmission information by a simple operation of uttering the transmission information. By these input methods, the driver can input transmission information even while driving.

  Alternatively, when the inter-vehicle communication device 2 receives traffic information from a nearby vehicle by inter-vehicle communication, the transmission information determination unit 21 may display the traffic information in the transmission information candidate list 201. Further, when the content of the traffic information is highly urgent, etc., the transmission information determination unit 21 irradiates the traffic information regardless of the driver's intention so as to automatically transmit it to the surrounding vehicles. It may be output to the position determination unit 22. The traffic information is information on events that occur around the vehicle, such as one-way traffic restrictions, traffic congestion, and accidents. In the example of FIG. 7, the transmission information icon “forward ahead with one-way restriction” is traffic information. The traffic information transmitted and received by the inter-vehicle communication is the information provided by the vehicle actually traveling the place, and thus the traffic information provided by VICS (Vehicle Information and Communication System, VICS is a registered trademark), etc. It is more immediate and more accurate than.

  Alternatively, when the distance sensor 3 detects an object such as a vehicle, a pedestrian, a bicycle, or a motorcycle, the transmission information determination unit 21 acquires the position information of the object from the distance sensor 3, and based on the position information of the object Transmission information may be generated. For example, when the distance sensor 3 detects a pedestrian located around the host vehicle, the transmission information determination unit 21 generates transmission information such as “Pedestrian attention!” And causes the transmission information candidate list 201 to be displayed. . Further, when the content of the generated transmission information is highly urgent, etc., the transmission information determination unit 21 generates the transmission regardless of the driver's intention so as to automatically transmit it to the surrounding vehicles. Information may be output to the irradiation position determination unit 22.

In step ST22, the irradiation position determination unit 22 receives the transmission destination vehicle and the transmission information from the transmission information determination unit 21, and also transmits the vehicle information of the communicable vehicle and the vehicle information of the non-communicable vehicle from the communication possibility determination unit 13. receive. The irradiation position determination unit 22 uses these pieces of information to determine whether the transmission destination vehicle can communicate with each other.
The irradiation position determination part 22 progresses to step ST23, when a transmission destination vehicle is a communication possible vehicle (step ST22 "YES"). On the other hand, when the transmission destination vehicle is the non-communicable vehicle (step ST22 “NO”), the irradiation position determination unit 22 proceeds to step ST24.

  In step ST23, the irradiation position determination unit 22 instructs the inter-vehicle communication device 2 to transmit the transmission information to the transmission destination vehicle. When the inter-vehicle communication device 2 receives the instruction from the irradiation position determination unit 22, the inter-vehicle communication device 2 transmits the transmission information to the transmission destination vehicle by the inter-vehicle communication. When the transmission destination vehicle receives the transmission information from the own vehicle by the inter-vehicle communication, the transmission destination vehicle transmits the transmission information to the driver of the transmission destination vehicle by displaying or outputting voice.

  When the transmission destination vehicle is a communicable vehicle, it is assumed that transmission information is directly transmitted to the transmission destination vehicle by inter-vehicle communication, so the information control system 1 basically does not emit light. However, the information control system 1 may light-emit the transmission information in step ST24 described later exceptionally, when the transmission destination vehicle does not have the display device or the voice output device or can not be used. In addition, information such as whether or not the transmission destination vehicle is equipped with a display device or the like, or whether or not it can be used, for example, is notified from the transmission destination vehicle to the host vehicle by inter-vehicle communication.

  In step ST24, the irradiation position determination unit 22 determines the shape of light representing the content of the transmission information and the position to which the light is irradiated, and outputs the determination result to the irradiation control unit 23. The irradiation control unit 23 controls the light irradiation device 25 based on the shape of the light received from the irradiation position determination unit 22 and the irradiation position, and light of a shape representing the content of the transmission information is a part of the vehicle or the periphery of the vehicle Irradiate the road surface.

Here, the process of step ST24 will be described in detail with reference to FIG.
FIG. 8 is a flowchart showing the details of step ST24 of FIG. In FIG. 8, the transmission destination vehicle is a non-communicable vehicle.
In step ST241, the irradiation position determination unit 22 refers to the vehicle information of the transmission destination vehicle to acquire the distance between the host vehicle and the transmission destination vehicle.

In step ST 242, the irradiation position determination unit 22 determines that the distance between the host vehicle and the transmission destination vehicle is less than one vehicle, or more than one vehicle, or less than the irradiation limit distance. Determine if
When the distance between the host vehicle and the destination vehicle is less than one vehicle, there is no space for emitting light between the host vehicle and the destination vehicle. Therefore, the irradiation position determination unit 22 proceeds to step ST243, and determines the irradiation position of light as the bonnet or rear glass of the host vehicle. For example, when the transmission destination vehicle is a rear vehicle, the irradiation position determination unit 22 determines the irradiation position of light to the rear glass. Further, for example, when the transmission destination vehicle is an oncoming vehicle, the irradiation position determination unit 22 determines the irradiation position of the light as the bonnet.
In the above example, the distance used to determine whether there is a space for emitting light between the host vehicle and the destination vehicle is set to one vehicle, but the distance is not limited to this value. , May be any value. For example, the irradiation position determination unit 22 has blind spot data for each vehicle type of the transmission destination vehicle, and based on the blind spot data corresponding to the vehicle type of the transmission destination vehicle recognized by the recognition device using the captured image of the camera. From this, it may be determined whether or not the irradiation can be performed at a position other than the dead angle, and whether the distance between the host vehicle and the transmission destination vehicle is less than the irradiation limit distance.

In step ST244, the irradiation position determination unit 22 determines the shape of light according to the content of the transmission information. For example, if the transmitted information is "sudden brake warning!", The irradiation position determination unit 22 may determine the character string "sudden brake warning!" To be the shape of light, or "sudden brake warning!" Symbols or figures representing contents may be determined as the shape of light. The irradiation position determination unit 22 may store in advance the correspondence between the content of the transmission information and the shape of the light.
The irradiation position determination unit 22 outputs the information on the determined irradiation position of light and the shape of the light to the irradiation control unit 23.

  On the other hand, when the distance between the host vehicle and the destination vehicle is one vehicle or more and less than the irradiation limit distance in step ST242, there is a space for emitting light between the host vehicle and the destination vehicle. Therefore, the irradiation position determination unit 22 proceeds to step ST245, and determines the irradiation position of light as a road surface around the host vehicle. For example, when the transmission destination vehicle is a rear vehicle, the irradiation position determination unit 22 determines the irradiation position of light as the road surface behind the host vehicle. As described above, the irradiation position determination unit 22 determines the position of the road surface on which the light is irradiated, according to the positional relationship between the host vehicle and the transmission destination vehicle.

In step ST246, the irradiation position determination unit 22 determines the shape of light according to the content of the transmission information. In addition, the irradiation position determination part 22 may change the shape of light with the case where it irradiates on the bonnet or rear glass of the own vehicle, and the case where it irradiates on a road surface, and may make it the same.
The irradiation position determination unit 22 outputs the information on the determined irradiation position of light and the shape of the light to the irradiation control unit 23.

  In step ST 247, the irradiation control unit 23 controls the light irradiation device 25 based on the irradiation position of the light received from the irradiation position determination unit 22 and the shape of the light, and causes the light irradiation device 25 to emit light.

  FIG. 9 is a view showing an example of light irradiation in the second embodiment of the present invention, in which the light irradiation device 25 irradiates the rear glass 222 of the vehicle 221 with light. This figure expresses the field of vision of the driver of the transmission destination vehicle located behind the host vehicle 221. For the driver of the transmission destination vehicle, the windshield 211, the rearview mirror 212 and the steering wheel 213 of the transmission destination vehicle are I can see it. The light irradiation device 25 of the own vehicle 221 irradiates the rear glass 222 with light of a character string “sudden braking attention!” Representing the content of the transmission information. The driver of the transmission destination vehicle visually recognizes the character string of "sudden braking attention!" Through the windshield 211. By the light irradiation, the intention of the driver of the host vehicle 221 is transmitted to the driver of the transmission destination vehicle.

  FIG. 10 is a diagram showing an example of light irradiation in the second embodiment of the present invention, in which the light irradiation device 25 irradiates light to the road surface behind the host vehicle 221. In FIG. The light irradiation device 25 of the own vehicle 221 irradiates the irradiation position 223 of the rear road surface with a figure representing the contents of the transmission information of "sudden braking attention!" The driver of the transmission destination vehicle 214 located behind the host vehicle 221 visually recognizes the figure irradiated to the irradiation position 223 through the windshield. By the light irradiation, the intention of the driver of the host vehicle 221 is transmitted to the driver of the transmission destination vehicle 214.

  On the other hand, when the distance between the host vehicle and the transmission destination vehicle is equal to or greater than the irradiation limit distance in step ST242, the light irradiation device 25 of the host vehicle can not emit light to a position visible to the driver of the transmission destination vehicle. Therefore, the irradiation position determination unit 22 proceeds to step ST248 and notifies the driver of the own vehicle that the transmission information can not be transmitted to the transmission destination vehicle. The notification method may be any method such as display or voice output. For example, the irradiation position determination unit 22 instructs the drawing unit 14 to display on the display device 4 a screen indicating that the transmission information can not be transmitted to the transmission destination vehicle.

  As described above, the information control device 10 according to the second embodiment includes the irradiation position determination unit 22 and the irradiation control unit 23. The irradiation position determination unit 22 determines the shape of light representing the content of the transmission information to be transmitted to the incommunicable vehicle determined by the communication determination unit 13, and at least one of a part of the target vehicle and the road surface. Is determined to be an irradiation position for irradiating light. The irradiation control unit 23 controls the light irradiation device 25 mounted on the target vehicle to irradiate the light of the shape determined by the irradiation position determination unit 22 to the irradiation position. The information control device 10 can transmit the transmission information to the non-communicable vehicle by irradiating the light of the shape representing the content of the transmission information to a part of the host vehicle or the road surface. Also, conventionally, only the headlights are lighted, blinked or passed, only a small amount of information can be transmitted, and only simple contents can be transmitted. On the other hand, in the second embodiment, since the shape of light is changed according to the content of transmission information, the amount of information that can be transmitted is large, and detailed content can be transmitted.

  Further, the irradiation position determination unit 22 of the second embodiment is configured to determine the shape of light based on the traffic information received by the inter-vehicle communication device 2. With this configuration, the information control apparatus 10 can not only communicate with the intention of the driver of the target vehicle, but also with traffic information received by vehicle-to-vehicle communication such as "with one-way traffic restriction ahead". Can be transmitted to

Third Embodiment
The driver basically recognizes the light in front because he looks at the front and drives, but it is difficult to recognize the light in side and rear. Therefore, the information control system 1 according to the third embodiment of the present invention is located around the transmission destination vehicle in a situation where the transmission destination vehicle incapable of inter-vehicle communication is in a position where it is difficult to notice the light emitted from the own vehicle. In cooperation with the communicable vehicle, light is emitted from the communicable vehicle to the destination vehicle.

FIG. 11 is a block diagram showing an example of the configuration of an information control system 1 according to Embodiment 3 of the present invention. An information control system 1 according to the third embodiment has a configuration in which an irradiation vehicle determination unit 31 is added to the information control system 1 of the second embodiment shown in FIG. Parts in FIG. 11 identical to or corresponding to those in FIG.
Further, in the third embodiment, not only the own vehicle but also the communicable vehicles located around the own vehicle are provided with the information control system 1.

  FIG. 12 is a flowchart showing an operation example of the information control system 1 according to the third embodiment of the present invention. Steps ST11 to ST14 and ST21 to ST24 in FIG. 12 are the same processes as steps ST11 to ST14 and ST21 to ST24 in FIG. However, in Steps ST21 and ST22 of the third embodiment, it is assumed that a non-communicable vehicle located in front of the host vehicle is selected as the transmission destination vehicle. The transmission information is, for example, the driver's intention such as "Be careful because there is overtaking" and traffic information such as "Attention to approach the motorcycle from the left rear".

  FIG. 13 is a diagram showing an example of the irradiation possible position 311 of the vehicle 301, the irradiation possible position 313 of the communicable vehicle 303, and the ideal irradiation position 312 of the transmission destination vehicle 302 in the third embodiment of the present invention. The “ideal irradiation position” is the front of the transmission destination vehicle 302, for example, the ideal irradiation position 312 on the road surface in front of the transmission destination vehicle 302 or the rear glass of the communicatable vehicle 303 located in front of the transmission destination vehicle 302 is there. Since the driver of the destination vehicle 302 basically looks forward and can drive, the light irradiated to the ideal irradiation position 312 can always be recognized, but there is a high possibility that the light irradiated to the side and the rear can not be recognized.

In FIG. 13, the driver of the host vehicle 301 wants to safely overtake the destination vehicle 302 ahead. Since the transmission destination vehicle 302 is a non-communicable vehicle, the information control system 1 of the own vehicle 301 can not transmit the driver's intention to the transmission destination vehicle 302 by inter-vehicle communication. Further, even if the information control system 1 of the host vehicle 301 emits light representing the driver's intention, the transmission destination vehicle 302 becomes an obstacle, and the light can not be emitted to the ideal irradiation position 312.
On the other hand, the communicable vehicle 303 located in front of the transmission destination vehicle 302 can emit light to the ideal irradiation position 312. Therefore, the information control system 1 of the own vehicle 301 cooperates with the information control system 1 of the communicable vehicle 303 to irradiate light from the communicable vehicle 303 to the rear ideal irradiation position 312. By the light irradiation from the communicable vehicle 303, the driver's intention of the own vehicle 301 is transmitted to the driver of the transmission destination vehicle 302.
Further, for example, when a communicable vehicle (not shown) is present in the lane next to the destination vehicle 302 on a road having two or more lanes, the information control system 1 of the vehicle 301 cooperates with the information control system 1 of the communicatable vehicle. Alternatively, light may be emitted from the communicable vehicle to the ideal illumination position 312 on the side.

In step ST31, the irradiation vehicle determination unit 31 refers to the registered vehicle information and extracts one or more communicable vehicles located around the transmission destination vehicle.
In step ST32, the irradiation vehicle determination unit 31 compares the position of the host vehicle, the position of the transmission destination vehicle, and the positions of one or more communicable vehicles extracted in step ST31, and emits light to the transmission destination vehicle. Decide which vehicles to The irradiation vehicle determination part 31 determines the vehicle which irradiates light with respect to a transmission destination vehicle by the method shown, for example in FIG. The inter-vehicle communication device 2 may receive the irradiable position of the communicable vehicle from the communicable vehicle by the inter-vehicle communication, or the standard irradiable position may be set in the irradiation vehicle determination unit 31 in advance. . When the irradiation vehicle determination unit 31 extracts a plurality of communicable vehicles in step ST31, the irradiation vehicle determination unit 31 selects one communicable vehicle at a position closest to the own vehicle, for example, in step ST32 You may compare the positional relationship with.

In step ST33, the irradiation vehicle determination unit 31 notifies the irradiation position determination unit 22 that the own vehicle is a vehicle that emits light, when the own vehicle can emit light to the ideal irradiation position of the transmission destination vehicle. The irradiation position determination part 22 which received this notification progresses to step ST24.
If the communicable vehicle located around the host vehicle can emit light to the ideal irradiation position of the transmission destination vehicle, the irradiation vehicle determination unit 31 proceeds to step ST34.
When neither the own vehicle nor the communicable vehicle can irradiate the light to the ideal irradiation position of the transmission destination vehicle, the irradiation vehicle determination unit 31 proceeds to step ST35.

  In step ST34, the irradiation vehicle determination unit 31 outputs the vehicle information of the transmission destination vehicle and the transmission information to the inter-vehicle communication device 2. The inter-vehicle communication device 2 transmits the vehicle information and the transmission information of the transmission destination vehicle received from the irradiation vehicle determination unit 31 to the communicable vehicle selected in step ST33.

  FIG. 14 is a diagram showing an example of light irradiation in the third embodiment of the present invention, which is an example of irradiating light to the road surface in front of the destination vehicle 302. The communicable vehicle 303 is mounted with the information control system 1 in the same manner as the host vehicle 301. When the information control system 1 of the communicable vehicle 303 receives the vehicle information and transmission information of the transmission destination vehicle 302 from the own vehicle 301 by inter-vehicle communication, the information control system 1 uses the received vehicle information and transmission information of the transmission destination vehicle 302 The processing of step ST24 of FIG. 12, that is, steps ST241 to ST247 of FIG. 8 is executed. As a result, the communicable vehicle 303 irradiates the light of the figure representing the content of the transmission information "Please be careful because there is overtaking" received from the host vehicle 301 to the irradiation position 304 of the road surface ahead of the transmission destination vehicle 302. . Thereby, the driver's intention of the own vehicle 301 is transmitted to the driver of the transmission destination vehicle 302.

  If the information control system 1 of the communicable vehicle 303 can not emit light to the transmission destination vehicle 302 in step ST 242, the information control system 1 can not transmit information to the information control system 1 of the own vehicle 301 in step ST 248 of FIG. To notify. When the information control system 1 of the own vehicle 301 receives the notification that the information can not be transmitted from the information control system 1 of the communicable vehicle 303, for example, with respect to another communicable vehicle extracted in step ST31 of FIG. Execute the process of

  In step ST35, the irradiation vehicle determination unit 31 notifies the driver of the own vehicle that the transmission information can not be transmitted to the transmission destination vehicle. The notification method may be any method such as display or voice output.

  In the above example, the information control system 1 of the own vehicle transmits the vehicle information and transmission information of the transmission destination vehicle to the information control system 1 of the communicable vehicle by inter-vehicle communication, and the transmission destination vehicle from the communicable vehicle Light was emitted. On the other hand, the information control system 1 of the own vehicle receives the vehicle information and the transmission information of the transmission destination vehicle from the information control system 1 of the communicable vehicle by the inter-vehicle communication, and causes the transmission destination vehicle to emit light. It can also be done. Specifically, in the information control system 1 of the own vehicle, the inter-vehicle communication device 2 outputs the received information to the transmission information determination unit 21 when the vehicle information and transmission information of the transmission destination vehicle are received from the communicatable vehicle. Do. The transmission information determination unit 21 outputs the vehicle information of the transmission destination vehicle and the transmission information to the irradiation position determination unit 22. The irradiation position determination unit 22 and the irradiation control unit 23 execute the process of step ST24 of FIG. 12, that is, steps ST241 to ST247 of FIG. 8 using the vehicle information and the transmission information of the transmission destination vehicle.

  As described above, the information control device 10 according to the third embodiment includes the irradiation vehicle determination unit 31. The irradiation vehicle determination unit 31 determines a communicable vehicle equipped with a light irradiation device capable of irradiating light to a position where an occupant of the non-communicable vehicle can visually recognize from among the communicable vehicles determined by the communication possibility determination unit 13 The inter-vehicle communication device 2 transmits the vehicle information indicating the incommunicable vehicle and the transmission information transmitted to the incommunicable vehicle to the determined communicable vehicle. With this configuration, when the information control device 10 of the target vehicle can not transmit the transmission information to the non-communicable vehicle by light irradiation, the occupant of the non-communicable vehicle from the light irradiation device mounted in the communicable vehicle around the target vehicle The light having a shape representing the content of the transmitted information can be emitted to a position where the image can be viewed.

According to this configuration, the information control apparatus 10 causes the communicable vehicle to emit light not only to the driver's intention of the target vehicle but also to traffic information received by inter-vehicle communication such as “with one-way restriction at the front”. Can be transmitted to a vehicle that can not communicate.
Further, the transmission information determination unit 21 may be configured to determine the transmission information to be transmitted to the incommunicable vehicle based on the position information of the object located around the target vehicle detected by the distance sensor 3. With this configuration, the information control apparatus 10 can not communicate by causing the communicable vehicle to emit light to traffic information detected not only by the driver of the target vehicle but also by the target vehicle such as “Pedestrian attention!” It can be transmitted to the vehicle.

  In addition, the information control device 10 according to the third embodiment includes the irradiation position determination unit 22 and the irradiation control unit 23. The irradiation position determination unit 22 determines the shape of light representing the content of the transfer information based on the vehicle information indicating the incommunicable vehicle received by the inter-vehicle communication device 2 and the transfer information to be transferred to the non-communicable vehicle. In addition, at least one of the part of the target vehicle and the road surface is determined to be the irradiation position for irradiating light. The irradiation control unit 23 controls the light irradiation device 25 mounted on the target vehicle to irradiate the light of the shape determined by the irradiation position determination unit 22 to the irradiation position. According to this configuration, the transmission information received from the communicable vehicle can be transmitted to the non-communicable vehicle by light irradiation.

  The information control system 1 of the target vehicle in the third embodiment is configured to transmit the vehicle information indicating the transmission destination vehicle and the transmission information to the information control system 1 of the communicable vehicle by inter-vehicle communication. The information control system 1 of the communicable vehicle is configured to determine the shape of the light and the irradiation position based on the vehicle information indicating the transmission destination vehicle received from the information control system 1 of the target vehicle and the transmission information. The Rather than the configuration, for example, the information control system 1 of the target vehicle transmits information including the ideal irradiation position of the transmission destination vehicle and the shape of light representing the content of the transmission information to the information control system 1 of the communicable vehicle It may be configured to transmit by communication. In the latter case, based on the information received from the information control system 1 of the target vehicle, the information control system 1 of the communicable vehicle emits light of a shape representing the content of the transmission information to the ideal irradiation position of the transmission destination vehicle.

Fourth Embodiment
The information control system 1 according to the fourth embodiment of the present invention automatically warns a rear vehicle having a short inter-vehicle distance so as to increase the inter-vehicle distance.

  An information control system 1 according to the fourth embodiment of the present invention has the same configuration as that of the information control system 1 of the second embodiment shown in FIG. Therefore, FIG. 5 is used below.

  FIG. 15 is a flowchart showing an operation example of the information control system 1 according to the fourth embodiment of the present invention. Steps ST11 to ST13 in FIG. 15 are the same processing as steps ST11 to ST13 in FIG. In addition, since steps ST242 to ST247 in FIG. 15 are the same processes as steps ST242 to ST247 in FIG. 8, the description will be omitted.

  In step ST41, the irradiation position determination unit 22 refers to the vehicle information of the rear vehicle located immediately behind the host vehicle to acquire the distance between the host vehicle and the rear vehicle. This rear vehicle is a transmission destination vehicle that can not communicate between vehicles.

  In step ST42, the irradiation position determination unit 22 determines whether the distance between the host vehicle and the rear vehicle is less than the distance necessary for the inter-vehicle communication device 2 to emit light. Here, the distance necessary for the inter-vehicle communication device 2 to emit light is taken as the distance for two vehicles.

  In step ST42, when the distance between the host vehicle and the rear vehicle is less than two vehicles, the inter-vehicle distance is short. Therefore, the irradiation position determination unit 22 proceeds to step ST43, and determines that a warning is required to increase the inter-vehicle distance to the rear vehicle. The irradiation position determination unit 22 sets the warning as transmission information, and executes the processing of steps ST242 to ST247 with the rear vehicle as the transmission destination vehicle. As a result, light of a shape representing the content of the warning is emitted to a part of the host vehicle or the road surface between the host vehicle and the rear vehicle. Thus, the information control system 1 can automatically warn the rear vehicle having a short inter-vehicle distance to increase the inter-vehicle distance. Further, the information control system 1 automatically warns when the inter-vehicle distance is less than two cars in step ST42, thereby shortening the inter-vehicle distance and making it possible to warn before the irradiation position on the road surface can not be secured. It can emit light.

  In step ST42, when the distance between the host vehicle and the rear vehicle is two or more vehicles, the inter-vehicle distance is long. Therefore, the irradiation position determination unit 22 proceeds to step ST44 and determines that the warning to the rear vehicle is unnecessary.

  In the above example, the distance used to determine whether to warn the driver to increase the inter-vehicle distance is set to two vehicles. However, the distance is not limited to this value and may be an arbitrary value. This distance may be set according to, for example, the size of the irradiation position (the irradiation position 223 or the like in FIG. 10) at which the inter-vehicle communication device 2 irradiates the road surface with light. It may be set according to an appropriate inter-vehicle distance based on the speed of the rear vehicle calculated from the transition of the distance to the rear vehicle. By setting this distance in accordance with the appropriate inter-vehicle distance based on the speed of the rear vehicle, it is determined that a warning is unnecessary when traffic jams or waiting for traffic lights.

  As described above, in the irradiation position determination unit 22 of the fourth embodiment, the inter-vehicle distance between the target vehicle and the non-communicable vehicle located behind the target vehicle is less than the distance necessary for the light irradiation device 25 to emit light. If so, the light representing the content for warning the inter-vehicle distance to be increased to the non-communicable vehicle is determined, and at least one of the target vehicle and the road surface is determined to be the irradiation position for emitting light. Configuration. With this configuration, the information control device 10 can automatically warn the rear vehicle to increase the inter-vehicle distance. In addition, the information control device 10 can secure the irradiation position on the road surface when the inter-vehicle distance between the target vehicle and the rear vehicle is short.
