Various information necessary for displaying these contents is acquired from the external camera, CAN, and the like by the input device 3, and is output from the input device 3 to the display control unit 15. The content shown in FIG. 3 is an example, and the combination and display position of the content are arbitrary.

The vehicle display control device 11 includes a content storage unit 12, a line-of-sight detection unit 13, a content detection unit 14, and a display control unit 15.

The content storage unit 12 stores the display position, display size, and the like on the meter cluster panel 10 of each of the plurality of contents. When each content is displayed on the meter cluster panel 10 based on the display position, display size, etc. stored in the content storage unit 12, the content arrangement example shown in FIG. 3 shall be used.

The line-of-sight detection unit 13 detects where the driver 53 is looking by analyzing the image captured by the in-vehicle camera 2. The line-of-sight detection unit 13 outputs the direction (line-of-sight 54 in FIG. 2) that the detected driver 53 is looking at to the content detection unit 14 as line-of-sight information.

The content detection unit 14 acquires the display positions of the plurality of contents stored in the content storage unit 12 and the line-of-sight information detected by the line-of-sight detection unit 13. Based on the acquired information, the content detection unit 14 detects the first content visually recognized by the driver 53 from among the plurality of contents displayed on the meter cluster panel 10. Subsequently, the content detection unit 14 detects the second content that the driver 53 visually recognizes within a predetermined time after the first content is visually recognized based on the acquired information. The content detection unit 14 outputs the detected first content and the detection result indicating the second content to the display control unit 15.

The display control unit 15 acquires the display positions and the like of each of the plurality of contents stored in the content storage unit 12. The display control unit 15 causes the meter cluster panel 10 to display various information from the input device 3 according to the display position and the like acquired from the content storage unit 12. In this state, when the display control unit 15 acquires the detection result indicating the first content and the second content from the content detection unit 14, the display control unit 15 moves the first content in the direction of the second content and displays it. ..

FIG. 4 is a flowchart showing an operation example of the vehicle display control device 11 according to the first embodiment. For example, when the ignition switch of the vehicle 50 is turned on, the vehicle display control device 11 starts the operation shown in the flowchart of FIG. 4, and when the ignition switch is turned off, the operation shown in the flowchart of FIG. 4 ends. Further, it is assumed that the line-of-sight detection unit 13 always detects the line-of-sight information of the driver 53 while the vehicle display control device 11 is performing the operation shown in the flowchart of FIG.

In step ST1, the content detection unit 14 acquires the line-of-sight information detected by the line-of-sight detection unit 13, and determines whether or not the driver 53 has seen the meter cluster panel 10 based on the acquired line-of-sight information. When it is determined that the driver 53 has seen the meter cluster panel 10 (step ST1 “YES”), the content detection unit 14 performs the operation of step ST2. When the content detection unit 14 determines that the driver 53 is not looking at the meter cluster panel 10 (step ST1 “NO”), the content detection unit 14 repeats the operation of step ST1.

In step ST2, the content detection unit 14 selects the content displayed on the meter cluster panel 10 based on the display position of the content stored in the content storage unit 12 and the line-of-sight information acquired in step ST1. The content visually recognized by the driver 53 is detected, and the detected content is set as the first content.

In step ST3, the content detection unit 14 acquires the line-of-sight information detected by the line-of-sight detection unit 13, and whether or not the driver 53 sees the meter cluster panel 10 again within a predetermined time based on the acquired line-of-sight information. Is determined. When the driver 53 determines that the meter cluster panel 10 has been viewed again within a predetermined time (step ST3 “YES”), the content detection unit 14 performs the operation of step ST4. When it is determined that the driver 53 has not seen the meter cluster panel 10 within a predetermined time (step ST3 “NO”), the content detection unit 14 performs the operation of step ST1. The content detection unit 14 may determine whether or not the driver 53 continues to look at the meter cluster panel 10 for a predetermined time.

In step ST4, the content detection unit 14 selects the content displayed on the meter cluster panel 10 based on the display position of the content stored in the content storage unit 12 and the line-of-sight information acquired in step ST3. The content visually recognized by the driver 53 is detected, and the detected content is set as the second content.

The predetermined time is a time for detecting two contents having a high relevance between the contents, which is necessary for the driver 53 to perform a certain driving operation, and is about several seconds.

In step ST5, the content detection unit 14 determines whether or not the first content and the second content are the same. When the first content and the second content are different from each other (step ST5 “NO”), the content detection unit 14 outputs a detection result indicating the first content and the second content to the display control unit 15. The display control unit 15 that has received this detection result performs the operation of step ST6. When the second content and the second content are the same (step ST5 “YES”), the content detection unit 14 performs the operation of step ST3.

In step ST6, the display control unit 15 moves the first content in the direction of the second content based on the display position of the content stored in the content storage unit 12 and the detection result from the content detection unit 14. The meter cluster panel 10 is controlled so as to be displayed in the vicinity of the second content. The display control unit 15 may move the first content in the direction of the second content as described above, and may leave the first content at the original display position. In this case, the display control unit 15 may leave the first content at the original display position as it is, duplicate the first content, and display it in the vicinity of the second content.

In step ST7, the display control unit 15 determines whether or not the driver 53 has instructed to release the movement display. For example, the input device 3 acquires the voice recognition result of the movement display release instruction uttered by the driver 53 from the voice recognition device and outputs it to the display control unit 15. Further, for example, the input device 3 acquires the result of the driver 53 operating the switch provided on the steering wheel 52 or the like from the switch and outputs the result to the display control unit 15. When the display control unit 15 receives the voice recognition result of the movement display release instruction or the switch operation via the input device 3, it is determined that the driver 53 has instructed the movement display release (step ST7 “YES”). The operation of step ST8 is performed. In other cases, the display control unit 15 determines that the driver 53 has not instructed to release the movement display (step ST7 “NO”), and repeats the operation of step ST7.

The display control unit 15 intends to release the movement display to the driver 53 when the driver 53 does not look at the meter cluster panel 10 for a long time based on the line-of-sight information of the driver 53 detected by the line-of-sight detection unit 13. It may be presumed that there is, and it may be determined that the movement display is canceled.

In step ST8, the display control unit 15 moves the meter cluster panel 10 to the original display position based on the display position of the content stored in the content storage unit 12. Control.

Next, a specific example will be described.
As an example, it is assumed that the driver 53 is visually recognizing the right rear image display unit 61 of the meter cluster panel 10 in order to make a right turn after this. Therefore, the content detection unit 14 detects the right rear image display unit 61 as the first content. After that, the driver 53 shall visually recognize the navigation display unit 66 in order to confirm the place to turn right. When the driver 53 visually recognizes the right rear image display unit 61 and then visually recognizes the navigation display unit 66 within a predetermined time, the content detection unit 14 detects the navigation display unit 66 as the second content. In the above case, the display control unit 15 controls the meter cluster panel 10 so as to move the right rear image display unit 61, which is the first content, to the vicinity of the navigation display unit 66, which is the second content.

FIG. 5 is a diagram showing an example of content arrangement of the meter cluster panel 10 in the first embodiment, and is an example in which the right rear image display unit 61a is moved. The display control unit 15 moves the display position of the right rear image display unit 61 in FIG. 3 to the display position of the right rear image display unit 61a in FIG. The driver 53 can turn right at a planned intersection while simultaneously visually recognizing the navigation display unit 66, which is the second content, and the right rear image display unit 61a, which is the first content. After turning right, the driver 53 no longer needs to visually recognize the navigation display unit 66 and the right rear image display unit 61a at the same time, and therefore instructs the driver 53 to cancel the movement display. The display control unit 15 returns the display position of the right rear image display unit 61a to the display position of the right rear image display unit 61 in FIG. 3 in accordance with the movement display release instruction.

When the display control unit 15 moves the first content to the vicinity of the second content, the display control unit 15 changes the display position of the content around the destination of the movement of the first content to increase the display space of the first content. You may secure it. Although not shown, the display control unit 15 replaces the display position of the right rear image display unit 61 with the display position of the engine speed display unit 65, so that the display control unit 15 has the first content, the right rear image display unit 61. You may secure the display space of the moving destination of.

As described above, the vehicle display device 1 according to the first embodiment includes a meter cluster panel 10 and a vehicle display control device 11 for controlling the contents to be displayed on the meter cluster panel 10. The vehicle display control device 11 includes a content storage unit 12, a line-of-sight detection unit 13, a content detection unit 14, and a display control unit 15. The content storage unit 12 stores the display positions of the plurality of contents on the meter cluster panel 10. The line-of-sight detection unit 13 detects the line-of-sight 54 of the driver 53. The content detection unit 14 has a plurality of contents displayed on the meter cluster panel 10 based on the display positions of the plurality of contents stored in the content storage unit 12 and the line of sight 54 detected by the line of sight detection unit 13. The first content visually recognized by the driver 53 is detected from among the contents, and after the first content is visually recognized, the second content visually recognized within a predetermined time is detected. The display control unit 15 moves the first content in the direction of the second content. In this way, when the driver 53 visually recognizes two different contents of the meter cluster panel 10 within a predetermined time, the vehicle display device 1 arranges the contents close to each other, so that the driver 53 The amount of movement of the line of sight is reduced. Further, by reducing the amount of movement of the line of sight, the driver 53 can easily visually recognize the content on the meter cluster panel 10 in a short time. Further, since the time until the line-of-sight movement between the contents with low relevance occurs is longer than the time until the line-of-sight movement between the contents with high relevance occurs, the vehicle display device 1 is determined in advance. By determining whether or not the line-of-sight movement has occurred within the set time, it is possible to move only the content having a high relevance between the contents from the plurality of contents displayed on the meter cluster panel 10. Further, the vehicle display device 1 can prevent the content having low relevance from moving against the intention of the driver 53.

Embodiment 2.
FIG. 6 is a block diagram showing a configuration example of the vehicle display device 1 according to the second embodiment.

FIG. 7 is a diagram showing an example of the positional relationship between the meter cluster panel 10 and the steering wheel 52 in the second embodiment. Due to the increase in size of the meter cluster panel 10 or the difference in the physique or posture of the driver 53, the line of sight 54 of the driver 53 facing the meter cluster panel 10 may be blocked by the steering wheel 52. Therefore, the vehicle display device 1 of the second embodiment realizes the content movement in the meter cluster panel 10 in consideration of the influence of the steering wheel 52. In FIG. 7, it is assumed that the initial display positions of the plurality of contents are set so as not to overlap the steering wheel 52 and are stored in the content storage unit 12.

The shielding determination unit 20 includes a steering wheel information storage unit 21 and a steering wheel angle detection unit 22. The steering wheel information storage unit 21 stores information related to the steering wheel 52, such as the mounting position and shape of the steering wheel 52. The steering wheel angle detection unit 22 acquires information indicating the rotation angle of the steering wheel 52 from the input device 3.
An operation example of the shielding determination unit 20 is shown below.

FIG. 8 is a flowchart showing an operation example of the vehicle display control device 11 according to the second embodiment. The operation of steps ST1 to ST8 in the flowchart of FIG. 8 is the same as the operation of steps ST1 to ST8 in the flowchart of FIG.

In step ST21 following step ST5, the shielding determination unit 20 determines whether or not the line of sight 54 of the driver 53 who sees the first content of the moving destination is shielded by the steering wheel 52.

Specifically, the shielding determination unit 20 acquires the detection result indicating the first content and the second content from the content detection unit 14. The shielding determination unit 20 calculates the display position and display size of the movement destination of the first content based on the display position and display size of each of the plurality of contents stored in the content storage unit 12, and the first content of the movement destination. The line of sight 54 of the driver 53 who sees the content of 1 is estimated. Then, the shielding determination unit 20 is based on the mounting position and shape of the steering wheel 52 stored in the steering wheel information storage unit 21, and the rotation angle of the steering wheel 52 detected by the steering wheel angle detection unit 22. It is determined whether or not the line of sight 54 of the driver 53 who sees the first content of the movement destination is blocked by the steering wheel 52. The shielding determination unit 20 may use the line-of-sight 54 directed to the second content detected in step ST3 as the line-of-sight 54 of the driver 53 who sees the first content at the destination. Further, the shielding determination unit 20 sees the first content of the moving destination based on the position of the eyes detected when the line-of-sight detection unit 13 detects the line-of-sight 54 of the driver 53. May be calculated.

When it is determined that the line of sight 54 of the driver 53 who sees the first content of the moving destination is shielded by the steering wheel 52 (step ST21 “YES”), the shielding determination unit 20 performs the operation of step ST22. In step ST22, the shielding determination unit 20 calculates a display position near the second content where the line of sight 54 of the driver 53 is not shielded by the steering wheel 52 as a destination for moving the first content. Alternatively, the shielding determination unit 20 shields the driver 53's line of sight 54 from the steering wheel 52 in place of the calculation of the unshielded display position or in addition to the calculation of the unshielded display position for the first content of the movement destination. The display size to be reduced may be calculated so as not to be reduced. The shielding determination unit 20 outputs at least one of the calculated display position and display size of the first content to the display control unit 15. In this case, the display control unit 15 controls the meter cluster panel 10 so as to change the display of the first content based on the display position or display size calculated by the shielding determination unit 20 in step ST6.

When the shielding determination unit 20 determines that the line of sight 54 of the driver 53 who sees the first content at the destination is not shielded by the steering wheel 52 (step ST21 “NO”), the first content detection unit 14 acquires the first content. The detection result indicating the content and the second content is output to the display control unit 15. In this case, in step ST6, the display control unit 15 moves the first content in the direction of the second content and displays it in the vicinity of the second content, as in the first embodiment. 10 is controlled.

FIG. 9 is a diagram showing an example of arranging the contents of the meter cluster panel 10 in the second embodiment, and is an example in which the right rear image display unit 61b is moved to a position not shielded by the steering wheel 52. In this example, the first content is the right rear image display unit 61, and the second content is the navigation display unit 66. According to the information from the shielding determination unit 20, the display control unit 15 sets the display position of the right rear image display unit 61 in FIG. 7 to the display position of the right rear image display unit 61b in FIG. 9 so as not to be shielded by the steering wheel 52.

FIG. 10 is a diagram showing a content arrangement example of the meter cluster panel 10 according to the second embodiment, and is an example in which the right rear image display unit 61c reduced to a display size not shielded by the steering wheel 52 is moved. Similar to FIG. 9, in FIG. 10, the first content is the right rear image display unit 61, and the second content is the navigation display unit 66. According to the information from the shielding determination unit 20, the display control unit 15 sets the display size of the right rear image display unit 61 in FIG. 7 to the display size of the right rear image display unit 61c in FIG. 10 so as not to be shielded by the steering wheel 52. After reducing the size, the image is moved to the display position of the right rear image display unit 61c.

The shielding determination unit 20 has a configuration in which at least one of the display position and the display size of the first content is changed so as not to be shielded by the steering wheel 52, but the present invention is not limited to this. For example, the shielding determination unit 20 may secure a display space for the first content by changing the display position of the content around the destination of the movement of the first content. In the examples of FIGS. 9 and 10, the shielding determination unit 20 replaces the display position of the right rear image display unit 61 with the display position of the engine speed display unit 65 to display the right rear image, which is the first content. A display space for the destination of the movement of the unit 61 is secured.

As described above, the vehicle display control device 11 according to the second embodiment includes the shielding determination unit 20. The shielding determination unit 20 determines whether or not the line of sight 54 of the driver 53 facing the first content after the movement is shielded by the steering wheel 52 when the first content is moved in the direction of the second content. When the determination is made and it is determined that the line of sight 54 of the driver 53 is shielded by the steering wheel 52, at least one of the display position and the display size that is not shielded by the steering wheel 52 is calculated. When the shielding determination unit 20 determines that the line of sight 54 of the driver 53 is shielded by the steering wheel 52, the display control unit 15 is based on at least one of the display position and the display size calculated by the shielding determination unit 20.

Is determined. The content already displayed at the destination of the first content is referred to as the "third content".

The display control unit 15 performs the operation of step ST42 when there is a third content at the destination of moving the first content (step ST41 “YES”). In step ST42, the display control unit 15 has a higher priority than the lower priority content based on the priority added to the first content and the priority added to the third content. The overlapping order of the first content and the third content is calculated so that the contents are displayed in an overlapping manner. In this case, the display control unit 15 moves the first content in the direction of the second content in step ST6, and overlaps the first content and the third content based on the overlapping order calculated in step ST42. In addition, the meter cluster panel 10 is controlled.

In step ST42, the display control unit 15 reduces the display size of the content having the lower priority based on the priority added to the first content and the priority added to the third content. May be calculated, and the display positions of the first content and the third content in the vicinity of the second content may be calculated. In this case, in step ST6, the display control unit 15 reduces the content having the lower priority so as to have the display size calculated in step ST42, and at the same time, the first content and the first content and the first content are placed at the display position calculated in step ST42. The meter cluster panel 10 is controlled so as to move the contents of 3.

When there is no third content at the destination of moving the first content (step ST41 “NO”), the display control unit 15 uses the first content as the second content in step ST6, as in the first embodiment. The meter cluster panel 10 is controlled so as to move in the direction of and display in the vicinity of the second content.

Since the priority of the right rear image display unit 61 is level 1 and the priority of the engine speed display unit 65 is level 2, the engine speed display unit 65 has a higher priority than the right rear image display unit 61. Low. Therefore, the right rear image display unit 61d after movement is displayed superimposed on the engine speed display unit 65.

FIG. 14 is a diagram showing an example of arranging the contents of the meter cluster panel 10 in the fourth embodiment, and is an example in which the engine speed display unit 65e is reduced. Similar to FIG. 13, in FIG. 14, the first content is the right rear image display unit 61, the second content is the navigation display unit 66, and the third content is the engine speed display unit 65. Since the engine speed display unit 65 has a lower priority than the right rear image display unit 61, the display size of the engine speed display unit 65 is reduced to the display size of the engine speed display unit 65e. Further, the right rear image display unit 61e is displayed in the space vacated by the reduction of the engine speed display unit 65e.

As described above, the content storage unit 12 of the fourth embodiment stores the display position on the meter cluster panel 10 of each of the plurality of contents and the priority of each of the plurality of contents. When the third content is already displayed at the destination of the first content, the display control unit 15 sets the high-priority content among the first content and the third content as the low-priority content. A display space for high-priority content is secured by displaying the content on top of it or reducing the low-priority content. As a result, the vehicle display device 1 can prevent the content arrangement of the meter cluster panel 10 from becoming complicated, and can realize the content arrangement that is easy for the driver 53 to recognize.
