[0024] First Embodiment A transportation facility display system S1 according to a first embodiment will be described with reference to the drawings.

[0025] (Hardware configuration of the traffic facility display system S1) As shown in FIG. 1, a traffic facility display system S1 includes a traffic facility display device 10.

[0026] The traffic facility display device 10 includes a CPU (Central Processing Unit: processor) 20, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 24, a storage 26, and a communication interface (communication I / F) 28. Each component is connected to each other so as to be able to communicate with each other via an internal bus (not shown).

[0027] The CPU 20 is a central processing unit that executes various programs and controls each part. That is, the CPU 20 reads the programs from the ROM 22 or the storage 26, and executes the programs using the RAM 24 as a working area. The CPU 20 also controls each of the above components and performs various arithmetic processing according to the programs recorded in the ROM 22 or the storage 26.

[0028] The ROM 22 stores various programs and various data. The RAM 24 temporarily stores programs or data as a working area. The storage 26 is composed of an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 22 or the storage 26 stores programs for performing traffic facility display processing, etc.

[0029] The communication I / F 28 is an interface for the traffic facility display device 10 to communicate with the wearable device 12 and other devices, and uses standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0030] Here, the traffic facility display device 10 is electrically connected to a wearable device 12 as a display device. The wearable device 12 is a glasses-type device of a head-mounted display type that uses AR (Augmented Reality) technology to display content such as images and text by superimposing it on the scenery outside the vehicle.

[0031] As shown in FIG. 4, the wearable device 12 includes a pair of left and right temple portions 12A that are hung on the user's ears, a pair of left and right lens holding portions 12B that are connected to the temple portions 12A, and a bridge portion 12C that connects the lens holding portions 12B to each other.

[0032] As shown in FIG. 1, the wearable device 12 includes a control unit 13, a camera unit 30, a display unit 32, and a sensor unit .

[0033] The control unit 13 includes a CPU 21, a ROM 23, a RAM 25, a storage 27, and a communication interface (communication I / F) 29. Each component is connected to each other via an internal bus (not shown) so as to be able to communicate with each other.

[0034] The CPU 21 is a central processing unit that executes various programs and controls each part. The ROM 23 stores various programs and various data. The RAM 25 temporarily stores programs or data as a working area. The storage 27 is a non-temporary recording medium configured by an HDD or SSD that stores various programs including an operating system and various data. In this embodiment, the ROM 23 or the storage 27 stores programs for controlling the wearable device 12, etc. The communication I / F 29 is an interface that allows the wearable device 12 to communicate with the traffic facility display device 10 and other devices.

[0035] The camera unit 30 is provided on the left lens holding portion 12B, and includes a camera that captures an image of the front (see FIG. 4). Image information of the front image captured by the camera of the camera unit 30 is transmitted to the control unit 13.

[0036] As shown in Fig. 4, the display unit 32 includes a left display panel 32L held by the left lens holding portion 12B and a right display panel 32R held by the right lens holding portion 12B. The display unit 32 is made of a transparent material and is configured to be placed in front of the user's eyes when the user wears the wearable device 12. Specifically, the left display panel 32L of the display unit 32 is placed in front of the user's left eye, and the display panel 32R is placed in front of the user's right eye. The display unit 32 is configured so that the user can view the scenery ahead through the left display panel 32L and the display panel 32R.

[0037] Furthermore, the left display panel 32L and the right display panel 32R constituting the display unit 32 each include a display capable of displaying an image, and are capable of displaying predetermined image information superimposed on the scenery ahead.

[0038] 1, the sensor unit 34 is configured to include sensors mounted on the wearable device 12. For example, the sensor unit 34 includes a sensor that detects the position and orientation of the wearable device 12. The sensor unit 34 may also include a sensor that detects the line of sight of the user wearing the wearable device 12. In addition, the wearable device 12 is provided with a battery (not shown), and the battery can supply power to the camera unit 30, the display unit 32, and the sensor unit 34.

[0039] (Functional configuration of the traffic facility display device 10) The traffic facility display device 10 realizes various functions using the above hardware resources. The functional configuration realized by the traffic facility display device 10 will be described with reference to FIG.

[0040] 2, the traffic facility display device 10 includes, as functional components, a location information acquisition unit 40, a speed calculation unit 42, a user situation determination unit 44, a other user information acquisition unit 46, a traffic facility display unit 48, and an information display unit 50. Each functional component is realized by the CPU 20 reading and executing a program stored in the ROM 22 or the storage 26.

[0041] The position information acquisition unit 40 acquires position information of the wearable device 12, which is a display device. Specifically, the position information acquisition unit 40 acquires the position information based on a signal from the sensor unit 34 of the wearable device 12. Note that, if it is clear that the user is a vehicle occupant, the position information of the wearable device 12 may be acquired indirectly based on a signal from a GPS (Global Positioning System) device mounted on the vehicle.

[0042] The speed calculation unit 42 calculates the speed of the user wearing the wearable device 12 based on the position information acquired at predetermined time intervals. The user status determination unit 44 determines whether the user is a pedestrian or a vehicle occupant from the user's speed calculated by the speed calculation unit 42. For example, the user status determination unit 44 may determine that the user is a pedestrian when the user's average speed in a predetermined time is equal to or less than a predetermined threshold. The user status determination unit 44 may also determine that the user is riding a two-wheeled vehicle such as a bicycle.

[0043] The other user information acquisition unit 46 acquires position information of other users around the user wearing the wearable device 12. The "other users" here refer to users wearing a similar wearable device 12. For example, the other user information acquisition unit 46 may acquire position information of other users by receiving signals transmitted from similar wearable devices within a predetermined range centered on the position of the user wearing the wearable device 12.

[0044] The traffic facility display unit 48 displays on the display unit 32 traffic facility images relating to traffic facilities pre-stored in the storage 26 as a memory unit so as to be superimposed in the user's line of sight. Here, the traffic facility display unit 48 displays traffic facility images corresponding to the user's current location information and direction. In addition, the traffic facility display unit 48 of the present embodiment displays traffic facility images such as roads, traffic signals, signs, lanes, and guardrails, as examples.

[0045] The information display unit 50 displays other information that does not correspond to transportation facility images on the display unit 32. Here, an example of the display contents displayed by the transportation facility display unit 48 and the information display unit 50 will be described with reference to Figs. 3 and 4.

[0046] Fig. 3 shows the front of the vehicle as seen from inside the vehicle cabin. As shown in Fig. 3, vehicles V1, V2, and V3 traveling ahead can be seen through a windshield glass 52 from inside the vehicle cabin.

[0047] Also, a building H can be seen to the right front of the vehicle, and a tree T can be seen to the left front of the vehicle. Here, in this embodiment, the road on which the vehicle is traveling is not well-maintained, and traffic facilities such as roads and traffic signals are not provided. In addition, reference numeral 54 in Fig. 3 indicates an instrument panel, and reference numeral 56 indicates a steering wheel.

[0048] 4, on the left display panel 32L (display unit 32), traffic facility images M1, M2, and M3 are displayed by the traffic facility display unit 48. In addition, on the left display panel 32L, a mark M4 that does not correspond to a traffic facility image is displayed by the information display unit 50.

[0049] The traffic facility image M1 is an image that mimics a road, and is displayed superimposed on the scenery ahead of the vehicle. Therefore, the traffic facility image M1 is displayed in a virtual three-dimensional space so that the road appears narrower in the distance than closer to the user. The traffic facility image M1 also includes an image of a road that branches off to the left, and the user can turn left along this road.

[0050] The traffic facility image M2 is an image that imitates a traffic signal, and is displayed with its color changing based on a predetermined lighting pattern. Here, the lighting pattern of the traffic facility image M2 is displayed so that the color changes at the same timing as seen by surrounding users. In addition, in this embodiment, as an example, the traffic facility image M2 is displayed in a floating state, but this is not limited thereto, and it may be displayed as if it is standing on the ground like an actual traffic signal.

[0051] The traffic facility image M3 is an image that imitates a sign indicating a speed limit, and is an image that is displayed only when the user is a vehicle occupant. In the present embodiment, as an example, the traffic facility image M3 is displayed in a state of floating in the air, but the present invention is not limited to this, and the image may be displayed as if it is standing on the ground like an actual sign. In addition, the traffic facility display unit 48 may display a stop line (not shown) or the like.

[0052] Mark M4 is superimposed on vehicle V1 and vehicle V3. Specifically, mark M4 is a mark for displaying the position information of other users in the vicinity, and in the state shown in Fig. 4, it can be seen that vehicle V1 and vehicle V3 are vehicles using similar wearable devices. On the other hand, since mark M4 is not displayed on vehicle V2, it can be seen that the occupant of vehicle V2 is not using a wearable device.

[0053] In this manner, the traffic facility images M1, M2, and M3 are displayed by the traffic facility display unit 48, and the mark M4 is displayed by the information display unit 50. In addition, the traffic facility display unit 48 changes the display mode of the traffic facility images based on the position information of other users present around the user.

[0054] Specifically, when there are no other users around the user, that is, when the vehicles V1 and V3 are not traveling in Fig. 4, the traffic facility display unit 48 changes the display mode of the traffic facility image. For example, the traffic facility display unit 48 may display the traffic facility image M1 simulating a road with a wider vehicle width. In addition, the traffic facility display unit 48 may display the traffic facility image M2 simulating a traffic signal in a color that allows constant progress.

[0055] Also, for example, in a situation where many other users are present around the user, the display mode may be changed so as to increase the number of lanes in the traffic facility image M1 simulating a road.

[0056] Next, another example of the display contents displayed by the transportation facility display unit 48 and the information display unit 50 will be described with reference to FIG.

[0057] As shown in FIG. 5, a building H and a tree T are visible ahead of a user who is a pedestrian wearing a wearable device 12.

[0058] Here, on the left display panel 32L (display unit 32), traffic facility images M5 and M6 are displayed by the traffic facility display unit 48. In addition, on the left display panel 32L, a mark M7 that does not correspond to a traffic facility image is displayed by the information display unit 50.

[0059] The traffic facility image M5 is an image that imitates a traffic signal, and is displayed with a color that changes based on a predetermined lighting pattern. The lighting pattern of the traffic facility image M5 is displayed so that the color changes at the same timing as seen by surrounding users.

[0060] The traffic facility image M6 is an image that imitates a pedestrian crossing, and is an image that is displayed only when the user is a pedestrian. That is, in this embodiment, the traffic facility display unit 48 changes the display mode of the image depending on whether the user is a pedestrian or a vehicle occupant.

[0061] Mark M7 is displayed on the right edge of the left display panel 32L and is an image of a vehicle pictogram and a rightward arrow. Mark M7 is a mark to alert the user that a vehicle is approaching from the right side.

[0062] (action) Next, the operation of this embodiment will be described.

[0063] (Transportation facility display processing) An example of a traffic facility display process by the traffic facility display device 10 will be described with reference to the flowchart shown in Fig. 6. This display process is executed by the CPU 20 reading a display program from the ROM 22 or the storage 26, expanding it in the RAM 24, and executing it.

[0064] In step S102, the CPU 20 acquires the location information. Specifically, the CPU 20 acquires the user's location information directly or indirectly using the function of the location information acquisition unit 40.

[0065] The CPU 20 calculates the speed in step S104. Specifically, the CPU 20 calculates the average speed of the user by using the function of the speed calculation unit .

[0066] In step S106, the CPU 20 determines whether the user is a pedestrian. Specifically, when the average speed is equal to or less than a predetermined threshold value by the function of the user status determination unit 44, the CPU 20 determines that the user is a pedestrian and proceeds to processing in step S108.

[0067] The CPU 20 displays an image in step S108. Specifically, the CPU 20 uses the function of the traffic facility display unit 48 to display a traffic facility image corresponding to the user's current location on the display unit 32 of the wearable device 12. At this time, the image displayed on the display unit 32 is only an image displayed to pedestrians, and no image is displayed to vehicle occupants. The CPU 20 also uses the function of the information display unit 50 to display other marks and the like that do not correspond to the traffic facility image on the display unit 32 of the wearable device 12. Then, the CPU 20 ends the traffic facility display process.

[0068] On the other hand, if the CPU 20 determines in step S106 that the user is not a pedestrian, the process proceeds to step S110. The CPU 20 displays an image in step S110. Specifically, the CPU 20 uses the function of the traffic facility display unit 48 to display a traffic facility image corresponding to the user's current location on the display unit 32 of the wearable device 12. At this time, the image displayed on the display unit 32 is only an image displayed to the vehicle occupants, and no image for pedestrians is displayed. The CPU 20 also uses the function of the information display unit 50 to display other marks and the like that do not correspond to the traffic facility image on the display unit 32 of the wearable device 12. Then, the CPU 20 ends the traffic facility display process.

[0069] As described above, in the traffic facility display device 10 according to this embodiment, the traffic facility image corresponding to the position information of the wearable device 12 is displayed on the display unit 32 so as to overlap with the user's line of sight. This makes it possible to build a traffic system even in an area where roads, traffic signals, and the like are not yet fully developed.

[0070] In addition, in this embodiment, when a user is driving a vehicle, if there are many users around, the display mode is changed to increase the number of lanes on the road, thereby making it possible to avoid congestion. Conversely, if there are no users around, the display mode is changed to change the display of the traffic lights so that the user does not have to stop, thereby improving convenience.

[0071] Furthermore, in this embodiment, when the user is a pedestrian, the annoyance can be reduced by displaying information on approaching vehicles and pedestrian crossings while hiding signs that are only necessary for the driver of the vehicle, as shown in Fig. 5. On the other hand, when the user is a passenger of the vehicle, the vehicle can be driven safely by displaying speed limit signs, as shown in Fig. 4.

[0072] Furthermore, in this embodiment, by looking at the mark M4, the user can grasp the position information of other users, and therefore can indirectly recognize non-users who are not using the traffic facility display device 10. This allows the user to behave in a manner that is conscious of non-users who cannot see the traffic facility image. For example, since the vehicle V2 in FIG. 4 is a non-user who cannot see the traffic facility image, it can be determined that the vehicle V2 is highly likely to proceed even if the traffic signal is emitting light in a color indicating a stop. On the other hand, since the other vehicles are traveling in a line, the occupants of the vehicle V2 can follow the other vehicles and travel in an orderly manner, even if they are non-users who are not using the traffic facility display device 10.

[0073] In this embodiment, the wearable device 12 that can be worn on the head of the occupant is used as a display device, so that the traffic facility image can be displayed following the line of sight of the occupant. Furthermore, even if the user gets off the vehicle and is walking, the traffic facility image can be viewed without any special operation by keeping the wearable device 12 attached.

[0074] <Second embodiment> Next, a transportation facility display system S2 according to a second embodiment will be described with reference to the drawings. Note that the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted as appropriate.

[0075] 7, a traffic facility display system S2 of the present embodiment includes a traffic facility display device 10 similar to that of the first embodiment. Here, the traffic facility display device 10 is electrically connected to a forward camera 62 and a display device 64.

[0076] The front camera 62 is mounted on the vehicle and is a camera that captures an image in front of the vehicle. The display device 64 is mounted on the vehicle and includes a display unit disposed in front of the driver's seat, and is a device that displays content such as images and characters using AR technology. For example, the display device 64 may be a head-up display device that projects an image on the windshield glass 52. Also, for example, the display device 64 may be a transparent display device equipped with a light control unit inside the windshield glass.

[0077] 8, a display unit 66 on which a traffic facility image is displayed by a display device 64 is provided on the windshield glass 52. For ease of explanation, the boundary of the display unit 66 is illustrated, but in reality, the display unit 66 is transparent and the boundary cannot be seen.

[0078] Traffic facility images M1, M2, and M3 are displayed on the display unit 66, as in the first embodiment. Also, a mark M4 is displayed above the vehicles V1 and V3. The traffic facility images M1, M2, and M3 are displayed by the function of the traffic facility display unit 48, and the mark M4 is displayed by the function of the information display unit 50.

[0079] (action) Next, the operation of this embodiment will be described.

[0080] In this embodiment, by disposing the display unit 66 of the display device 64 at the front of the vehicle interior including the driver's seat, it is possible to visually recognize images of traffic facilities in front of the vehicle without wearing a dedicated device such as a wearable device. Other operations are the same as those of the first embodiment.

[0081] Although the traffic facility display systems S1 and S2 according to the first and second embodiments have been described above, it is needless to say that the present invention can be embodied in various forms without departing from the gist of the present invention. For example, in the above embodiment, a traffic facility image resembling a traffic signal is displayed in a place where there is no traffic signal, but the present invention is not limited to this. That is, an image may be superimposed on a broken traffic signal. Specifically, the operation status of the traffic signal may be acquired, and if there is a traffic signal that is not working, the image of the traffic signal may be superimposed on the position of the traffic signal. This makes it possible to maintain the traffic system even in a situation where the traffic signal does not function due to a power outage or the like.

[0082] In the above embodiment, as shown in Fig. 4, the mark M4 indicating other surrounding users has been described, but the present invention is not limited thereto. For example, the position information of non-users who are not equipped with the traffic facility display device 10 and are present around the user may be displayed. That is, in Fig. 4, a mark similar to the mark M4 may be placed on the vehicle V2, which is a non-user. In this case, the user can intuitively grasp the vehicle to be careful of, compared to the case where a mark is placed on the user.

[0083] Furthermore, in the above embodiment, the information display unit 50 displays images that do not correspond to traffic facility images as the marks M4 and M7, but may display other images. For example, the information display unit 50 may display disaster information, etc. on the display unit 32 in the event of a disaster. [Explanation of symbols]
