< action >
Next, the operation of the display control device 4 will be described.
Fig. 4 is a flowchart showing an example of the operation of the display control apparatus 4.
In step S1, when the vehicle drives the engine, the following processing is performed.
In step S2, the control unit 11 determines whether or not wind information is displayed. Specifically, the control unit 11 determines whether or not the user has performed an operation indicating that wind information is displayed via the operation input unit 18. When the wind information is displayed, the process proceeds to step S3. On the other hand, if the wind information is not displayed, the process proceeds to step S11.
In step S3, the basic information acquiring unit 5 acquires basic information. Specifically, the weather information acquiring unit 2 acquires weather information including at least one of the wind direction and the wind intensity.
In step S4, the own vehicle information acquisition unit 7 acquires own vehicle information. Specifically, the vehicle information acquisition unit 7 acquires at least information related to the vehicle speed and information related to the current position of the vehicle.
In step S5, the vehicle periphery information acquiring unit 6 acquires the vehicle periphery information. Specifically, the vehicle periphery information acquiring unit 6 acquires a video captured by the camera 15.
In step S6, the traveling road specifying unit 9 specifies the current position of the vehicle. Specifically, the travel road specifying unit 9 specifies the current position of the vehicle on the map based on the current position of the vehicle acquired by the vehicle information acquiring unit 7 and the map data stored in the map data storage unit 8.
In step S7, the traveling road specifying unit 9 specifies a traveling road as a road on which the vehicle is traveling. Specifically, the traveling road specifying unit 9 specifies the traveling road based on the current position of the vehicle on the map specified in step S6 and the map data stored in the map data storage unit 8.
In step S8, the display information generation unit 12 performs a display information generation process for generating display information. In addition, details of the display information generation processing will be explained later.
In step S9, the display information generator 12 performs a display combining process of combining the display information generated in step S8. Specifically, when the display information is displayed on the HUD16, the display information generation unit 12 performs display combination processing so that the display information is displayed at a predetermined position of the HUD 16. When the display information is displayed on the monitor 17, the display information generating unit 12 performs display combining processing so that the display information is displayed at a predetermined position on the monitor 17.
In step S10, the HUD output control unit 13 performs control to output the display information generated by the display information generation unit 12 to the HUD 16. The monitor output control unit 14 also performs control to output the display information generated by the display information generation unit 12 to the monitor 17.
In step S11, the control unit 11 determines whether or not the engine of the vehicle is stopped. When the engine of the vehicle is stopped, the process is ended. On the other hand, if the engine of the vehicle is not stopped, the process proceeds to step S2.
< display information generating processing >
Next, the display information generation process performed by the display information generation unit 12 in step S8 in fig. 4 will be described. Hereinafter, a case where the display information generating unit 12 generates wind information as the display information will be described. The display information generating unit 12 generates wind information that is three-dimensionally displayed on at least one of the HUD16 and the monitor 17.
Here, differences between the two-dimensional display and the three-dimensional display will be described with reference to fig. 5 to 7. As shown in fig. 5 to 7, in the case of two-dimensional display, an arrow is formed from left to right along the X-axis direction. On the other hand, when three-dimensional display is performed, an arrow having a depth from the point Cs to the point Ce with the point Cm as the center is formed. In the example of fig. 5, the depth direction is the Y-axis direction.
Fig. 8 to 11 are diagrams showing an example of the wind information generated by the display information generating unit 12.
In the example of fig. 8, the display information generation unit 12 generates the 1 st object 21, which is one-dimensional of an arrow, as wind information. As shown in fig. 8, the 1 st object 21 indicates the wind direction, and has a depth from the point Cs to the point Ce with the point Cm as the center.
In the example of fig. 9, the display information generating unit 12 generates the 1 st object 21 as an arrow and the 2 nd two-dimensional object 22 attached to the 1 st object 21 as wind information. As shown in fig. 9, the 1 st object 21 indicates the wind direction, and has a depth from the point Cs to the point Ce with the point Cm as the center. The 2 nd object 22 is 3 circular rings arranged in parallel to the 1 st object 21.
In the example of fig. 10, the display information generating unit 12 generates the 1 st object 21 as an arrow and the 2 nd object 22 attached to the 1 st object 21 as wind information. As shown in fig. 10, the 1 st object 21 indicates the wind direction, and has a depth from the point Cs to the point Ce with the point Cm as the center. The 2 nd object 22 is arranged orthogonally to the 1 st object 21, and is 3 circular rings arranged in a direction orthogonal to the 1 st object 21. The 3 rings are centered on the 1 st object 21.
In the example of fig. 11, the display information generating unit 12 generates the 1 st object 21 as an arrow and the 2 nd object 22 attached to the 1 st object 21 as wind information. As shown in fig. 11, the 1 st object 21 indicates the wind direction, and has a depth from the point Cs to the point Ce with the point Cm as the center. The 2 nd object 22 is arranged orthogonally to the 1 st object 21, and is 3 circular rings arranged in a direction parallel to the 1 st object 21. The 3 rings are larger in size as they are oriented in the direction of the wind shown by the wind direction with the 1 st object 21 as the center.
When the wind information shown in fig. 8 to 11 is three-dimensionally displayed as the wind information shown in fig. 8 and 9, the direction indicated by the arrow may not be easily known from the angle of observation, and it may be difficult to appropriately display the wind information. On the other hand, the wind information shown in fig. 10 and 11 clearly shows three dimensions, and therefore, has an advantage of being easily understood when three-dimensional display is performed.
In fig. 9 to 11, the 2 nd object 22 is shown as 3 rings, but the present invention is not limited thereto, and at least 1 or more rings may be used. The 2 nd object 22 may have an arbitrary shape, not a circular ring.
The 1 st object 21 shown in fig. 8 to 11 may have any shape as long as it shows the wind direction, and may have a shape shown in fig. 12 and 13, for example. Fig. 12 is a view of the 1 st object 21 as viewed from above, and fig. 13 is a view of the 1 st object 21 as viewed from the lateral direction.
Fig. 14 is a diagram showing an example of the display of the wind information shown in fig. 10, and shows an observation mode of the wind information observed from the driver. In fig. 14, as the intensity of the wind increases, the length of the 1 st object 21 is increased and the color thereof is changed, and the color of the 2 nd object 22 is changed. The intensity of the wind is divided into 3 levels, each level being distinguished based on a predetermined threshold value of the wind speed. Thus, the driver can easily grasp the wind direction and the intensity of the wind regardless of the direction of the wind. In fig. 14, the color of the tip of the arrow is made darker to make the wind direction easier to see.
Fig. 15 is a diagram showing an example of the display of the wind information, and shows the manner of observation of the wind information as seen from the driver. In fig. 15, as the intensity of the wind increases, the colors of the 1 st object 21 and the 2 nd object 22 change. The intensity of the wind is divided into 3 levels, each level being distinguished based on a predetermined threshold value of the wind speed. Thus, the driver can easily grasp the wind direction and the intensity of the wind regardless of the direction of the wind. In fig. 15, the color of the tip of the arrow is made darker to make the wind direction easier to see.
Fig. 16 is a diagram showing an example of the display of the wind information shown in fig. 11, and shows an observation mode of the wind information observed from the driver. As shown in fig. 16, the 2 nd object 22 is constituted by circular rings a, b, c. The intensity of the wind is divided into 3 levels, each level being distinguished based on a predetermined threshold value of the wind speed. In fig. 16, as the intensity of the wind increases, the color of the 2 nd object 22 changes. Specifically, the color of the circle a is changed when the wind is the strongest, the color of the circle b is changed when the wind is the 2 nd strongest, and the color of the circle c is changed when the wind is the weakest. The wind information shown in fig. 16 is compared with the wind information shown in fig. 15, and the wind direction and the intensity of the wind can be presented in an easily understandable manner even if the angle at which the driver observes the wind information changes.
In fig. 14 to 16, the intensity of the wind of 3 levels is shown, but the present invention is not limited thereto, and the intensity of the wind of a plurality of levels may be shown. In this case, in fig. 16, the 2 nd object 22 needs to be the same number of rings as the number of levels of the wind intensity.
In fig. 14 to 16, the threshold value of the wind intensity may be changed according to the vehicle speed. For example, when the vehicle speed is fast, the threshold value of the intensity of the wind is lowered. The threshold value of the intensity of the wind may be changed according to the wind direction. For example, when there is a wind lateral to the vehicle, the threshold value of the intensity of the wind is lowered.
Fig. 17 to 20 are diagrams showing an example of the display of the wind information, and show a case where only the 1 st object 21 is displayed.
In the example of fig. 17, the wind direction is emphasized by vibrating the 1 st object 21. In addition, the wind information shown in fig. 17 may be directly displayed. In this case, for example, the color of the 1 st object 21 indicating the wind direction may be made dark, and the color of the other 21 st objects 21 may be made light.
In the example of fig. 18, the 1 st object 21 is oscillated in an arc shape along the double arrow. Further, the larger the change in wind, the larger the amplitude of the vibration. In addition, the wind information shown in fig. 18 may be directly displayed. That is, the 1 st object 21 may be displayed together with the double arrow. In this case, the length of the double arrow may be changed according to the change of the wind.
In the example of fig. 19, as the wind becomes stronger, the length of the 1 st object 21 is lengthened. In the example of fig. 20, the intensity of a predetermined wind is used as a reference d1Changing the wind to a reference d1D is the amount of change when the strength is required2To be presented. Specifically, the ratio is a predetermined reference d1When the wind of (1) th object 21 is blown by the wind of which the intensity is strong, the length of the object is extended by the change amount d2。
< example >
Next, an example of actually displaying the display information generated by the display information generating unit 12 will be described.
Fig. 21 and 22 are diagrams showing an example of display of wind information. Fig. 21 shows a case where wind blows at a constant intensity. Fig. 22 shows a case where the intensity of wind varies depending on the location.
As shown in fig. 21, 22, wind information is shown in HUD 16. The driver who operates the steering wheel 24 to drive sees the wind information as a virtual image superimposed on the scene seen across the front windshield 23. The wind information is displayed at points 10m, 100m, and 200m from the current position of the vehicle in the traveling direction.
The interval of the positions at which the wind information is displayed may be changed according to the vehicle speed. For example, if the vehicle speed is faster, the wind information may be displayed at the points 10m, 500m, and 1000m from the current position, and if the vehicle speed is slower, the wind information may be displayed at the points 5m, 50m, and 100m from the current position. This processing is performed by the display control unit 3.
In fig. 21 and 22, the wind information at 3 points is shown, but not limited thereto. It is sufficient that wind information is displayed for at least 1 place.
In fig. 21 and 22, wind information at a predetermined point is displayed based on a route along which the vehicle will travel in the future. The route on which the vehicle will travel in the future may be the route searched by the route searching unit 10, but if the route search is not performed, the route on which the vehicle will travel in the future may be estimated based on the trajectory of the current position of the vehicle and the map data.
Fig. 23 and 24 are diagrams showing an example of a case where the wind information is displayed as an animation. Fig. 23 shows a trajectory of the 1 st object 21 as wind information. Fig. 24 is a diagram obtained by dividing the track of fig. 23 every 1 frame. The display information shown in fig. 24 is sequentially displayed in succession, thereby providing the animation display shown in fig. 23. By performing animation display, the driver can easily grasp the flow of wind.
Fig. 25 to 27 are diagrams showing an example of a case where wind information is displayed as a moving image. Fig. 25 is a diagram showing the wind information shown in fig. 21 in animation. Fig. 26 is a diagram showing the wind information shown in fig. 22 in animation. Fig. 27 shows a case where the flow of the wind is not stable. As shown in fig. 27, even when the flow of wind has no stability, the driver can easily grasp the flow of wind.
Fig. 28 is a diagram showing an example of display of wind information in consideration of geographical conditions. As shown in fig. 28, wind information is not displayed for a place where the building 25 exists in front of the vehicle, and wind information is displayed only for a place where the building 25 does not exist. The information of the building is stored in the map data storage unit 8. In addition, although the building 25 is shown as an example in fig. 28, the building is not limited to this, and may be any object as long as it is an obstacle that blocks the wind. In the case where there is an obstacle such as the building 25, wind is often not blown to such an extent that the influence of the vehicle is eliminated, and it is not necessary to display wind information in such a place. As shown in fig. 28, the driver can easily grasp the wind information by displaying the wind information only for the places that affect the vehicle.
Fig. 29 and 30 are diagrams showing an example of display of wind information when a vehicle enters or exits a tunnel. Fig. 29 shows wind information near the entrance of the tunnel. Fig. 30 shows wind information near the exit of the tunnel. The information of the tunnel is stored in the map data storage unit 8. The wind direction and the intensity of the wind are often different between the inside and the outside of the tunnel, and it is useful for the driver to display the wind information shown in fig. 29 and 30. In addition, no wind information is displayed within the tunnel.
Fig. 31 is a diagram showing an example of display of wind information when wind blows from above. Fig. 32 is a diagram showing an example of display of wind information when wind blows upward from below. Even in this case, the driver can easily grasp the wind information.
Fig. 33 and 34 are diagrams showing an example of changing the color of a predetermined display area of the HUD16 corresponding to the direction in which the vehicle is windy. In fig. 33, the color change of the right end region of the HUD16 is shown, and wind blows from the right side of the vehicle at a point 10m ahead of the current position of the vehicle. Fig. 34 shows a color change in the upper right end area of the HUD16, and the wind blows from the upper right of the vehicle at a point 10m ahead of the current position of the vehicle. In this way, the driver can easily grasp the wind direction by changing the color of the predetermined display area so that the wind direction can be recognized. In fig. 33 and 34, the direction in which the vehicle receives wind at a point 10m ahead of the current position of the vehicle is described, but the present invention is not limited to this, and the direction in which the vehicle receives wind at an arbitrary point ahead of the current position of the vehicle may be used.
Fig. 35 is a diagram showing an example of a display of a simulation result of the wind direction and the wind intensity received by the vehicle when the vehicle travels a predetermined distance from the current position of the vehicle. Fig. 36 to 43 show an example of the simulation result displayed on the monitor 17. 44-57 illustrate one example of simulation results displayed on the display area 27 of the HUD 16.
As shown in fig. 35, the simulation result of the wind direction and the wind intensity received when the vehicle has traveled 10m from the current position is displayed on the predetermined display area 27 of the HUD 16. The simulation result is displayed on the monitor 17 in superimposition with the video in front of the vehicle captured by the camera 15. At this time, the monitor 17 is switched to enable three-dimensional display.
Fig. 36 shows a case where the vehicle receives wind from the right. Fig. 37 shows a case where the vehicle receives wind from the front. Fig. 38 shows a case where the vehicle receives wind from the left. Fig. 39 shows a case where the vehicle receives wind from the front left. Fig. 40 shows a case where the vehicle receives wind from the front right. Fig. 41 shows a case where the vehicle receives wind from diagonally upper left. Fig. 42 shows an animation of a case where wind is received from the right side of the vehicle. Fig. 43 shows a case where the vehicle receives wind from behind.
Fig. 44 and 45 show a state where the vehicle receives wind from the right. Fig. 46 and 47 show a case where the vehicle receives wind from the front. Fig. 48 and 49 show the case where the vehicle receives wind from the left. Fig. 50 and 51 show a case where the vehicle receives wind from the front left. Fig. 52 and 53 show a case where the vehicle receives wind from the front right. Fig. 54 and 55 show a case where the vehicle receives wind from diagonally upper left. Fig. 56 and 57 show a case where the vehicle receives wind from behind.
As shown in fig. 36 to 57, a square or rectangular plate is displayed in a direction perpendicular to the wind direction received by the vehicle. By displaying the panel, the driver can easily grasp the wind direction.
In fig. 35 to 57, a case where simulation results of the wind direction and the wind intensity received when the vehicle travels 10m from the current position are displayed is described as an example, but the present invention is not limited thereto, and simulation results of the wind direction and the wind intensity received when the vehicle travels an arbitrary distance from the current position may be displayed.
As described above, according to the present embodiment, the wind direction in the depth direction is presented by three-dimensionally displaying wind information, and therefore, the driver can intuitively grasp the wind direction. Further, by displaying wind information of a predetermined point from the current position of the vehicle, the driver can know the wind information of the travel destination in advance.
