  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
First, the configuration of the multi-display control apparatus according to Embodiment 1 of the present invention will be described. In the following description, it is assumed that the multi-display control device is mounted in a vehicle.

  FIG. 1 is a block diagram illustrating an example of the configuration of the multi-display control device 1.

  As shown in FIG. 1, a multi-display control device 1 includes a map image generation unit 2, an information image generation unit 3, a related graphic generation unit 4, a display control unit 5, a map data storage unit 6, a navigation unit. 7, an information acquisition unit 8, and a display device arrangement management unit 9.

  The display controller 5 is connected to a CID (Center Information Display) 10, a HUD (Head-Up Display) 11, and an ICD (Instrumental Cluster Display) 12.

  The CID 10 has a function as a map display device that displays a map as a map image, and the HUD 11 and the ICD 12 have a function as an information display device that displays information other than a map as an information image.

  The map image generation unit 2 generates a map image based on the map data stored in the map data storage unit 6.

  The information image generation unit 3 generates guide information on the route as an information image based on the route searched by the navigation unit 7. Moreover, the information image generation part 3 produces | generates the road traffic information on a path | route as an information image based on the path | route searched in the navigation part 7, and the road traffic information which the information acquisition part 8 acquired from the outside.

  When the information other than the map and the position information on the map are related, the related graphic generation unit 4 is based on the arrangement relationship of the CID 10, the HUD 11, and the ICD 12 managed by the display device arrangement management unit 9. Thus, a related graphic indicating that the CID 10 is related to the HUD 11 or the ICD 12 is generated. Here, the information other than the map includes the above-described guidance information or road traffic information.

  The display control unit 5 controls to display the map image generated by the map image generation unit 2 on the CID 10, and controls to display the information image generated by the information image generation unit 3 on the HUD 11 or the ICD 12. Moreover, the display control part 5 is controlled to display a related figure on each of CID10 and HUD11 or ICD12, when information other than a map and the positional information on a map are related.

  The map data storage unit 6 stores map data.

  The navigation unit 7 searches for a route from the current position to the destination based on the destination and the current position set by the user (for example, the driver) before the start of driving. At this time, the navigation unit 7 may search for a route using the map data stored in the map data storage unit 6.

  The information acquisition unit 8 acquires road traffic information from, for example, an external road traffic information center.

  The display device arrangement management unit 9 manages the arrangement positions of the CID 10, the HUD 11, and the ICD 12. In the first embodiment, the display device arrangement management unit 9 stores information on the arrangement positions of the CID 10, the HUD 11, and the ICD 12 that are set in advance.

  CID10 displays a map as a map image. Further, when the information other than the map and the position information on the map are related, a related graphic is displayed. CID10 is installed in the front part between a driver's seat and a passenger seat.

  HUD11 and ICD12 display information other than a map as an information image. Further, when the information other than the map and the position information on the map are related, a related graphic is displayed. The ICD 12 is a display unit provided in an instrument panel.

  Next, the operation of the multi-display control device 1 will be described.

  FIG. 2 is a flowchart showing an example of the operation of the multi-display control device 1. FIG. 3 is a diagram illustrating an example of display on the CID 10, the HUD 11, and the ICD 12.

  In step S11, the display control unit 5 displays a map on the CID 10, and determines whether information other than the map is displayed on the HUD 11 and the ICD 12. If it is displayed, the process proceeds to step S12. On the other hand, if not displayed, the process ends.

  For example, as shown in FIG. 3, the CID 10 displays a map image generated by the map image generation unit 2.

  In addition, the HUD 11 displays a warning image indicating “100m ahead dangerous goods”. Specifically, when the information image generation unit 3 acquires the falling object (dangerous object) information acquired by the information acquisition unit 8, the information image generation unit 3 calculates the distance from the current position to the point where the falling object is falling. Is generated as a warning image (information image). The warning image generated by the information image generation unit 3 is displayed on the HUD 11.

  The ICD 12 displays a guidance image indicating a right turn. Specifically, the information image generation unit 3 generates guidance information such as a left or right turn at the nearest intersection from the current position on the route searched by the navigation unit 7 as a guidance image (information image). The guidance image generated by the information image generation unit 3 is displayed on the ICD 12.

  As described above, the information image displayed on the HUD 11 and the ICD 12 has more detailed information than the map image displayed on the CID 10.

  In step S <b> 12, the related graphic generation unit 4 determines whether or not the position information on the map displayed on the CID 10 and the information displayed on the HUD 11 and the ICD 12 are related. If so, the process proceeds to step S13. On the other hand, if it is not related, the process is terminated.

  In step S <b> 13, the related graphic generation unit 4 generates related graphic 19 and 20. Specifically, the related graphic generation unit 4 uses the latitude / longitude information (that is, the position where the falling object exists) used when the information image generation unit 3 generates the information image (warning image). Information), and the latitude and longitude scale information of the map generated by the map image generation unit 2 is acquired. And the position coordinate of the fallen object on the map image produced | generated by the map image production | generation part 2 is produced | generated. Thereafter, a triangular figure having the position coordinates of the falling object as the apex and the HUD 11 side and the bottom side displaying the information of the falling object is generated as the related figure 19 (see FIG. 3). That is, the related graphic generation unit 4 generates the related graphic 19 indicating that the information content of the warning image displayed on the HUD 11 is more detailed than the map image displayed on the CID 10.

  In addition, the related graphic generation unit 4 includes latitude / longitude information (here, position information of an intersection performing a right turn guide) included in the guide information used when the information image generation unit 3 generates the information image (guide image). And the latitude / longitude scale information of the map generated by the map image generation unit 2 is acquired. Then, the position coordinates of the intersection on the map image generated by the map image generation unit 2 are generated. Thereafter, a triangular figure with the position coordinates of the intersection as the vertex and the ICD 12 side displaying the right turn guidance information as the base is generated as the related figure 20 (see FIG. 3). That is, the related graphic generation unit 4 generates the related graphic 20 indicating that the information content of the guide image displayed on the ICD 12 is more detailed than the map image displayed on the CID 10.

  As described above, when the related graphic generation unit 4 generates the related graphic 19 and 20 for each of the information displayed on the HUD 11 and the information displayed on the ICD 12, each related information can be distinguished. Alternatively, a color set in advance may be applied to each of the related figures 19 and 20. The color applied to the related figures 19 and 20 may be set according to the type of related information (for example, red for fallen object information and yellow for guidance information).

  In step S <b> 14, the display control unit 5 controls the related graphics 19 and 20 generated by the related graphic generation unit 4 to be displayed on the CID 10, the HUD 11, and the ICD 12 (see FIG. 3).

  From the above, according to the first embodiment, it is possible to understand the positional relationship between CID10, HUD11, and ICD12, and to accurately and easily determine the relevance of information displayed on each of CID10, HUD11, and ICD12. It becomes possible to grasp. Moreover, the content of information can be easily grasped by setting the color of the related graphic according to the type of related information.

<Embodiment 2>
FIG. 4 is a block diagram showing an example of the configuration of the multi-display control apparatus 1 according to the second embodiment of the present invention.

  As shown in FIG. 4, the second embodiment is characterized by including a gaze target determination unit 13 and an input device 14. Other configurations are the same as those of the first embodiment (see FIG. 1), and thus description thereof is omitted here.

  Examples of the input device 14 include a line-of-sight acquisition camera that acquires the line of sight of the user (operator), and a selection unit that allows the user to select any one of CID10, HUD11, and ICD12. Examples of the selection unit include a hard key provided in the input device 14, and the user may select a display device (any one of CID10, HUD11, and ICD12) to be watched.

  The gaze target determination unit 13 determines which of the CID 10, HUD 11, and ICD 12 is the gaze target. For example, when the input device 14 is a line-of-sight acquisition camera, the gaze target determination unit 13 determines a gaze target based on the user's line of sight acquired by the line-of-sight acquisition camera. When the input device 14 is a selection unit, the gaze target determination unit 13 determines a gaze target based on the selection by the selection unit.

  FIG. 5 is a flowchart showing an example of the operation of the multi-display control device 1. FIG. 6 is a diagram illustrating an example of display on the CID 10, the HUD 11, and the ICD 12. In addition, since step S21-step S24 of FIG. 5 perform the process similar to step S11-step S14 of FIG. 2, detailed description is abbreviate | omitted here.

  In step S21, the display control unit 5 displays a map on the CID 10, and determines whether information other than the map is displayed on the HUD 11 and the ICD 12. If it is displayed, the process proceeds to step S22. On the other hand, if not displayed, the process ends.

  In step S <b> 22, the related graphic generation unit 4 determines whether the position information on the map displayed on the CID 10 and the information displayed on the HUD 11 and the ICD 12 are related. If so, the process proceeds to step S23. On the other hand, if it is not related, the process is terminated.

  In step S23, the related graphic generation unit 4 generates a related graphic.

  In step S24, the display control unit 5 controls to display the related graphic generated by the related graphic generation unit 4 on the CID 10, the HUD 11, and the ICD 12.

  In step S25, the gaze target determination unit 13 determines whether the gaze target is the ICD 12. If the gaze target is the ICD 12, the process proceeds to step S26. On the other hand, when the gaze target is not the ICD 12, the process ends.

  In step S26, the display control unit 5 performs control so as not to display the related graphic displayed on the HUD 11 that is not the target of gazing and the related graphic displayed on the CID 10 related to the related graphic (see FIG. 6). . That is, the display control unit 5 controls to display the related graphic 21 only on the CID 10 and the ICD 12.

  In step S27, the gaze target determination unit 13 determines whether or not the gaze target has changed from ICD 12 to CID 10. When the gaze target is changed to CID10, the process proceeds to step S28. On the other hand, if the gaze target has not changed to CID10, the process ends. The time required to determine whether or not the gaze target has changed from ICD 12 to CID 10 may be set in advance.

  In step S <b> 28, the related graphic generation unit 4 highlights and displays position information (points) on the map displayed on the CID 10. Specifically, an intersection (guidance point) on the map corresponding to the right turn guidance image displayed on the ICD 12 is highlighted. As a highlighting method, for example, an animation display that enlarges / reduces a point (a black dot) shown on an intersection may be used, but any method can be used as long as a point on a map can be highlighted. . In other words, after the related graphic 21 is displayed for the CID 10 and the ICD 12 that is determined to be the gaze target, the related graphic generation is performed when the gaze target determination unit 13 determines that the gaze target has been changed from the ICD 12 to the CID 10. The unit 4 emphasizes the position information displayed on the CID 10.

  From the above, according to the second embodiment, the positional relationship of each of CID10, HUD11, and ICD12 is known, and the relevance of information displayed on each of CID10, HUD11, and ICD12 is determined according to the first embodiment. It becomes possible to grasp more accurately and easily. In addition, particularly when there are a plurality of display devices such as CID10, HUD11, and ICD12, only the information required by the user can be displayed, so that the relevance of information can be grasped more accurately and easily. It becomes. Moreover, since the related graphic regarding the information which the user is not paying attention is not displayed, the processing load for displaying the related graphic can be reduced.

<Embodiment 3>
The third embodiment of the present invention is characterized in that the related graphic generation unit 4 generates an icon as a related graphic. Note that the configuration of the multi-display control apparatus 1 according to the third embodiment is the same as that of the first embodiment (see FIG. 1), and thus the description thereof is omitted here.

  FIG. 7 is a flowchart showing an example of the operation of the multi-display control device 1. 8 and 9 are diagrams showing an example of display on the HUD 11. In addition, since step S31 and step S32 of FIG. 7 perform the process similar to step S11 and step S12 of FIG. 2, detailed description is abbreviate | omitted here.

  In step S <b> 31, the display control unit 5 displays a map on the CID 10 and determines whether information other than the map is displayed on the HUD 11. If it is displayed, the process proceeds to step S32. On the other hand, if not displayed, the process ends.

  In step S <b> 32, the related graphic generation unit 4 determines whether the position information on the map displayed on the CID 10 and the information displayed on the HUD 11 are related. If so, the process proceeds to step S33. On the other hand, if it is not related, the process is terminated.

  In step S33, the related graphic generation unit 4 generates an icon as the related graphic. Specifically, the related graphic generation unit 4 stores in advance icons indicating the characteristics of the CID 10, the HUD 11, and the ICD 12, and uses the stored icons. Examples of the icon include an icon that indicates the arrangement relationship between CID10, HUD11, and ICD12, and an icon that mimics the shape characteristics of CID10, HUD11, and ICD12.

  In step S <b> 34, the display control unit 5 controls to display the icon generated by the related graphic generation unit 4 on the HUD 11.

  For example, in FIG. 8, an icon indicating an arrangement relationship with the CID 10 displaying the map image is displayed on the HUD 11. At this time, the arrangement relationship between the CID 10 and the HUD 11 is, for example, the arrangement relationship illustrated in FIG.

  In FIG. 9, an icon simulating the shape of the instrument panel provided with the ICD 12 is displayed on the HUD 11. In this case, it is assumed that a map image is displayed on the ICD 12.

  Although the case where an icon is displayed on the HUD 11 has been described above, an icon may be displayed on the CID 10 or the ICD 12 as well.

  From the above, according to the third embodiment, the positional relationship between CID10, HUD11, and ICD12 can be understood, and the relevance of information displayed on each of CID10, HUD11, and ICD12 can be accurately and easily determined. It becomes possible to grasp.

<Embodiment 4>
FIG. 10 is a block diagram showing an example of the configuration of the multi-display control apparatus 1 according to Embodiment 4 of the present invention.

  As shown in FIG. 10, the fourth embodiment is characterized in that a display device connection state monitoring unit 15 is provided. Other configurations are the same as those of the first embodiment (see FIG. 1), and thus description thereof is omitted here.

  The display device connection status monitoring unit 15 monitors the connection status of the CID 10, the HUD 11, and the ICD 12. Here, the connection state refers to a state in which the power of the CID 10, the HUD 11, and the ICD 12 is ON / OFF (electrical ON / OFF state), or a state in which no information other than a map or map is displayed on the CID 10, the HUD 11, and the ICD 12 Functional ON / OFF state). That is, when the connection state is ON, information other than the map and the map is displayed, and when the connection state is OFF, the information other than the map and the map is not displayed. Therefore, the display device connection state monitoring unit 15 monitors the display / non-display state of the map and information other than the map in the CID 10, the HUD 11, and the ICD 12.

  The display control unit 5 controls display or non-display of related graphics based on monitoring by the display device connection state monitoring unit 15.

  FIG. 11 is a flowchart showing an example of the operation of the multi-display control device 1. 12 and 13 are diagrams showing examples of display on the CID 10, the HUD 11, and the ICD 12. Since steps S41 to S44 in FIG. 11 perform the same processes as steps S11 to S14 in FIG. 2, detailed description thereof is omitted here.

  In step S41, the display control unit 5 displays a map on the CID 10, and determines whether information other than the map is displayed on the HUD 11 and the ICD 12. If it is displayed, the process proceeds to step S42. On the other hand, if not displayed, the process ends.

  In step S42, the related graphic generation unit 4 determines whether or not the position information on the map displayed on the CID 10 and the information displayed on the HUD 11 and the ICD 12 are related. If so, the process proceeds to step S43. On the other hand, if it is not related, the process is terminated.

  In step S <b> 43, the related graphic generation unit 4 generates related graphic 22 and 23.

  In step S44, the display control unit 5 controls the related graphics 22 and 23 generated by the related graphic generation unit 4 to be displayed on the CID 10, the HUD 11, and the ICD 12 (see FIG. 12).

  In step S45, the display device connection state monitoring unit 15 determines whether or not the HUD 11 is in a non-display state. When the HUD 11 is in the non-display state, the process proceeds to step S46. On the other hand, if the HUD 11 is not in the non-display state, the process is terminated.

  In step S46, the display control unit 5 controls not to display the related graphic 22 displayed on the CID 10 related to the related graphic 22 displayed on the HUD 11 (see FIG. 13).

  Although the case where the HUD 11 is in the OFF state has been described above, the same applies to the case where the ICD 12 is in the OFF state. Further, when the CID 10 is turned off, the display control unit 5 performs control so that the related graphics 22 and 23 are not displayed on the HUD 11 and the ICD 12.

  As described above, according to the fourth embodiment, it is possible to accurately and easily grasp the relevance of information displayed on each of the CID 10, the HUD 11, and the ICD 12. Further, since the related graphic is displayed only on the display device whose connection state is ON, it is possible to suppress useless movement of the line of sight by the user.

  Note that the display device connection state monitoring unit 15 may monitor whether the map display device (here, CID 10) has a split view function. In this case, when the display device connection state monitoring unit 15 determines that the CID 10 has the split view function, the display control unit 5 can display the related graphic only from one direction side (for example, the driver side) of the CID 10. The display may be controlled so that can be seen, and the same effect as described above can be obtained.
