Embodiments for Carrying Out the Invention

[0012] A display control device according to an aspect of the present disclosure includes a detection unit that detects a failed display among a plurality of displays, and when the failed display is detected, based on the display priorities set for each of a plurality of display contents that were displayed on the plurality of displays before the failed display was detected, a display content selection unit that selects one or more display contents with higher priorities among the plurality of display contents, and based on the tolerance of display position change set for each of the plurality of display contents, from the display contents with lower tolerances among the one or more display contents, the displacement with respect to the position where the same display content was displayed before the failed display was detected is made smaller, a display position determination unit that determines the display positions on one or more displays other than the failed display among the plurality of displays, and a display switching unit that causes each of the one or more display contents to be displayed at the display position of the display content.

[0013] According to this, one or more display contents with higher priority among a plurality of display contents can be selected, and the selected one or more display contents can be displayed on one or more displays other than the failed display. Therefore, when a failed display is detected, it is possible to easily display the display contents that are preferentially to be displayed among the plurality of display contents. Also, from the display contents with lower tolerance among the one or more display contents, the display position can be determined so that the displacement with respect to the position where the same display content was displayed before the failed display was detected becomes smaller. Therefore, before and after the detection of the failed display, it is possible to easily make the displacement of the display position of the display contents that are not desired to be changed as much as possible smaller. In this way, when a failed display is detected, it is possible to easily display the display contents that are preferentially to be displayed among the plurality of display contents, and at the same time, it is possible to easily make the displacement of the display position of the display contents that are not desired to be changed as much as possible smaller before and after the detection of the failed display.

[0014] Also, in the display control device according to one aspect of the present disclosure, the display content selection unit selects the one or more display contents such that the area of the one or more images indicating the one or more display contents, each of which has the same size as the image that showed the same display content before the failed display was detected, is equal to or less than the area of the display region of the one or more displays. The display position determination unit determines the position in the one or more displays so that the displacement with respect to the position where the image showing the display content with lower tolerance among the one or more images showed the same display content before the failed display was detected becomes smaller, thereby determining the display position of each of the one or more display contents. The display switching unit may display each of the one or more display contents at the determined position of the display content by displaying each of the one or more images at the determined position.

[0015] According to this, one or more images showing one or more display contents, each of which has the same size as the image that showed the same display content before the failure display was detected, can be used to easily select one or more display contents and easily determine the display position of each of the one or more display contents. Therefore, when a failure display is detected, it is possible to more easily display the display content that is preferentially to be displayed among the plurality of display contents, and it is possible to more easily make the displacement of the display position of the display content that is not desired to change the display position as much as possible before and after the detection of the failure display smaller.

[0016] Also, in the display control device according to one aspect of the present disclosure, the display content selection unit selects one or more images showing the one or more display contents, at least one of which is a reduced image reduced from the image that showed the same display content before the failure display was detected or an alternative image of the image that showed the same display content before the failure display was detected, so that the area of the one or more images is equal to or less than the area of the display region of the one or more displays, and the display position determination unit determines the position in the one or more displays so that the displacement from the position where the image showing the display content with the lower tolerance among the one or more images was displayed to the position where the image that showed the same display content before the failure display was detected is smaller, thereby determining the display position of each of the one or more display contents, and the display switching unit may display each of the one or more images at the determined position, thereby displaying each of the one or more display contents at the display position of the display content.

[0017] According to this, one or more images showing one or more display contents, at least one of which is a reduced image that is smaller than an image that showed the same display content before the malfunctioning display was detected or an alternative image of an image that showed the same display content before the malfunctioning display was detected, can be used to easily select one or more display contents and easily determine the display position of each of the one or more display contents. Therefore, when a malfunctioning display is detected, it is possible to more easily display the display content that is desired to be preferentially displayed among the plurality of display contents, and it is possible to more easily make the displacement of the display position of the display content for which it is not desired to change the display position as little as possible before and after the detection of the malfunctioning display smaller.

[0018] Also, in the display control device according to one aspect of the present disclosure, when the malfunctioning display is restored, the display switching unit may display each of the plurality of display contents at the position where it was displayed before the malfunctioning display was detected.

[0019] According to this, when the malfunctioning display is restored, each of the plurality of display contents can be displayed at the position where it was displayed before the malfunctioning display was detected.

[0020] Also, in the display control device according to one aspect of the present disclosure, the plurality of displays may include at least one of a display arranged in front of the driver's seat of the vehicle and displaying two or more of the plurality of display contents, a display arranged in front of the passenger seat of the vehicle and displaying two or more of the plurality of display contents, a display included in the electronic side mirror on the right side of the vehicle and displaying one of the plurality of display contents, a display included in the electronic side mirror on the left side of the vehicle and displaying one of the plurality of display contents, a display included in the electronic rearview mirror of the vehicle and displaying one of the plurality of display contents, and a display arranged for the rear seats of the vehicle and displaying one or more of the plurality of display contents.

[0021] According to this, when a failed display is detected from any one of a plurality of displays including a display disposed in front of the driver's seat of a vehicle, a display disposed in front of the passenger seat of the vehicle, a display included in an electronic side mirror on the right side of the vehicle, a display included in an electronic side mirror on the left side of the vehicle, a display included in an electronic rearview mirror of the vehicle, and a display disposed for a rear seat of the vehicle, among one or more displays other than the failed display, it is possible to easily display the display content that is preferentially to be displayed among the plurality of display contents, and it is possible to easily make the displacement of the display position of the display content that is not desired to change the display position as little as possible before and after the detection of the failed display.

[0022] Further, a display control method according to an aspect of the present disclosure includes a detection step of detecting a failed display among a plurality of displays, and when the failed display is detected, based on the display priority set for each of the plurality of display contents displayed on the plurality of displays before the failed display is detected, a display content selection step of selecting one or more display contents having a higher priority among the plurality of display contents, and based on the allowable degree of display position change set for each of the plurality of display contents, from the display contents having a lower allowable degree among the one or more display contents, a display position determination step of determining the display position in one or more displays other than the failed display among the plurality of displays so that the displacement with respect to the position where the same display content was displayed before the failed display is detected becomes smaller, and a display switching step of displaying each of the one or more display contents at the display position of the display content.

[0023] According to this, the same operational effects as those of the above-described display control device are achieved.

[0024] Further, a program according to an aspect of the present disclosure is a program for causing a computer to execute the above-described display control method.

[0025] According to this, the same operational effects as those of the above-described display control device are achieved.

[0026] Hereinafter, embodiments will be specifically described with reference to the drawings.

[0027] Note that all of the embodiments described below are examples showing comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, the components not described in the independent claims are described as optional components. Also, each figure is a schematic diagram and is not necessarily drawn precisely. Also, in each figure, the same constituent members are denoted by the same reference numerals.

[0028] (Embodiment) FIG. 1 is a schematic diagram showing a plurality of displays 1a to 1d according to an embodiment. FIG. 1 schematically shows a state of viewing the plurality of displays 1a to 1d from the rear side of a vehicle in which the plurality of displays 1a to 1d are installed. First, with reference to FIG. 1, the plurality of displays 1a to 1d will be described.

[0029] The plurality of displays 1a to 1d are installed in a vehicle. For example, the vehicle is an automobile or the like.

[0030] The display 1a is disposed in front of the driver's seat of the vehicle. The display 1a displays display contents toward the rear side of the vehicle. Here, the display 1a displays two or more of the plurality of display contents, and the two or more display contents are displayed side by side in the left-right direction of the vehicle. The two or more display contents are contents related to an odometer, contents related to a speedometer, and contents related to a fuel gauge.

[0031] Display 1b is arranged in front of the passenger seat of the vehicle and to the left of Display 1a. Display 1b displays the display content towards the rear side of the vehicle. Here, Display 1b is displaying two or more of the plurality of display contents, and the two or more display contents are arranged side by side in the left - right direction of the vehicle. The two or more display contents are contents related to the air conditioner, contents related to navigation, and contents related to the radio.

[0032] Display 1c is included in the electronic side mirror on the right side of the vehicle and is arranged to the right of Display 1a. Display 1c displays the display content towards the rear side of the vehicle. Here, Display 1c is displaying one of the plurality of display contents. The one display content is the content of the image taken of the rear right side of the vehicle.

[0033] Display 1d is included in the electronic side mirror on the left side of the vehicle and is arranged to the left of Display 1b. Display 1d displays the display content towards the rear side of the vehicle. Here, Display 1d is displaying one of the plurality of display contents. The one display content is the content of the image taken of the rear left side of the vehicle.

[0034] Figure 2 is a block diagram showing the functional configuration of the display control device 10 and the like according to the embodiment. Next, with reference to Figure 2, the functional configuration of the display control device 10 and the like will be described.

[0035] As shown in Figure 2, the display control device 10 includes a failure detection unit 11, a priority setting unit 12, priority data 13, a display content selection unit 14, a tolerance setting unit 15, tolerance data 16, a display position determination unit 17, and a display switching unit 18. For example, the failure detection unit 11 is composed of a sensor or the like, and the priority setting unit 12, the display content selection unit 14, the tolerance setting unit 15, the display position determination unit 17, and the display switching unit 18 are composed of a processor, a memory, and the like. In this embodiment, the display control device 10 is installed in the vehicle.

[0036] The failure detection unit 11 detects a failed display, which is one of the plurality of displays 1a to 1d. For example, the failure detection unit 11 is connected to each of the plurality of displays 1a to 1d, and when any one of the plurality of displays 1a to 1d cannot display the display content normally, the display that cannot display the display content normally is detected as the failed display.

[0037] The priority setting unit 12 sets the priority of the display input from the priority setting screen 2 and outputs priority data 13 indicating the set priority. For example, the priority setting screen 2 is displayed on the display 1a or the display 1b, accepts the input of the priority of each of the plurality of display contents, and the priority setting unit 12 sets the priority of each of the plurality of display contents.

[0038] When the failed display is detected, the display content selection unit 14 selects one or more display contents with higher priority among the plurality of display contents based on the priority of the display set for each of the plurality of display contents displayed on the plurality of displays 1a to 1d before the failed display is detected. That is, the display content selection unit 14 selects one or more display contents in descending order of the priority among the plurality of display contents. For example, when the display content selection unit 14 selects three display contents among the plurality of display contents, the display content with the highest priority, the display content with the second highest priority, and the display content with the third highest priority among the plurality of display contents are selected.

[0039] For example, the display content selection unit 14 selects one or more display contents such that the area of one or more images indicating one or more display contents, each of which has the same size as the image that showed the same display content before the failed display was detected, is less than or equal to the area of the display area of one or more displays.

[0040] Further, for example, the display content selection unit 14 selects one or more images indicating one or more display contents, at least one of which is a reduced image smaller than an image that showed the same display content before the failure display was detected or an alternative image of an image that showed the same display content before the failure display was detected, such that the size of the one or more images is equal to or less than the size of the display area of the one or more displays.

[0041] The tolerance setting unit 15 sets the tolerance of the display position change input from the tolerance setting screen 3 and outputs tolerance data 16 indicating the set tolerance. For example, the tolerance setting screen 3 is displayed on the display 1a or the display 1b, accepts input of the tolerance for each of a plurality of display contents, and the tolerance setting unit 15 sets the tolerance for each of the plurality of display contents.

[0042] The display position determination unit 17 determines the display positions on one or more displays other than the failed display among the plurality of displays 1a to 1d so that, based on the tolerance of the display position change set for each of the plurality of display contents, the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller for the display content with a lower tolerance among the one or more display contents selected by the display content selection unit 14. That is, the display position determination unit 17 determines the display positions in ascending order of the low tolerance among the one or more display contents. For example, when three display contents are selected by the display content selection unit 14, the display position determination unit 17 determines the display position of the display content with the lowest tolerance among the three display contents so that the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller, then determines the display position of the display content with the second lowest tolerance so that the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller, and then determines the display position of the display content with the third lowest tolerance so that the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller. The display position determination unit 17 determines the display position so that, for each of the one or more display contents, if it can be displayed at the same position as the position where the same display content was displayed before the failed display was detected, it is displayed at the same position. Also, the display position determination unit 17 determines the display position so that, for each of the one or more display contents, if it cannot be displayed at the same position as the position where the same display content was displayed before the failed display was detected, it is displayed at a position as close as possible to the same position.

[0043] For example, the display position determination unit 17 determines the display position of each of the one or more display contents by determining the position in the one or more displays such that the displacement with respect to the position where the image showing the same display content was displayed before the failure display was detected is smaller from the image showing the display content with a lower tolerance among the one or more images showing the one or more display contents. For example, when three display contents are selected by the display content selection unit 14, the display position determination unit 17 determines the position of the image showing the display content with the lowest tolerance among the three images showing the three display contents such that the displacement with respect to the position where the image showing the same display content was displayed before the failure display was detected is smaller, and then determines the position of the image showing the display content with the second lowest tolerance such that the displacement with respect to the position where the image showing the same display content was displayed before the failure display was detected is smaller, and then determines the display position of the image showing the display content with the third lowest tolerance such that the displacement with respect to the position where the image showing the same display content was displayed before the failure display was detected is smaller.

[0044] Also, for example, the display position determination unit 17 sets the number of the one or more display contents as N, sets each of the one or more display contents as display content i (1 ≤ i ≤ N), sets the position of the display content i before the failure display is detected as (x i , y i ), sets the position of the display content i after the failure display is detected as (x' i , y' i ), and when the tolerance of the display content i is a i , determines the position of the display content i after the failure display is detected such that the evaluation function L represented by the following formula (1) is minimized.

[0045]

Equation

[0046] The display switching unit 18 causes each of one or more pieces of display content selected by the display content selection unit 14 to be displayed at the display position of the corresponding display content determined by the display positioning unit 17.

[0047] For example, the display switching unit 18 causes each of one or more pieces of display content to be displayed at the display position of the corresponding display content by causing each of one or more images indicating the one or more pieces of display content to be displayed at the determined position.

[0048] Also, for example, when it is determined that each of one or more images indicating one or more pieces of display content is to be an alternative image, the display switching unit 18 causes the alternative image to be displayed at the determined position, when it is determined to be reduced, causes it to be displayed reduced at the determined position, and when it is determined to remain as the image, causes the image to be displayed as it is at the determined position, thereby causing each of the one or more pieces of display content to be displayed at the display position of the corresponding display content.

[0049] Also, for example, when the failure display is restored, the display switching unit 18 causes each of a plurality of pieces of display content to be displayed at the position where it was displayed before the failure display was detected.

[0050] FIG. 3 is a flowchart showing an example of a display control method by the display control device 10 of FIG. 1. Next, with reference to FIG. 3, an example of a display control method by the display control device 10 will be described.

[0051] As shown in FIG. 3, the priority setting unit 12 sets the priority of each of a plurality of pieces of display content (step S1). The tolerance setting unit 15 sets the tolerance of each of the plurality of pieces of display content (step S2). Note that step S1 may be performed before step S2.

[0052] The display content selection unit 14 determines whether a failure display has been detected by the failure detection unit 11 (detection step) (step S3).

[0053] When the failure display is not detected by the failure detection unit 11 (No in step S3), the display content selection unit 14 determines again whether the failure display has been detected by the failure detection unit 11 (step S3).

[0054] When the failure display is detected by the failure detection unit 11 (Yes in step S3), the display content selection unit 14 selects, as candidates, one or more display contents with higher priorities among the plurality of display contents displayed on the plurality of displays 1a to 1d before the failure display is detected, based on the display priorities set for each of the plurality of display contents (step S4). For example, the display content selection unit 14 may select one or more display contents excluding the display content with the lowest priority among the one or more display contents selected in step S4.

[0055] The display content selection unit 14 determines whether all of the one or more images indicating the one or more display contents selected as candidates can be arranged on the one or more displays (step S5). That is, the display content selection unit 14 determines whether the one or more images indicating the one or more display contents selected as candidates fit within the display areas of the one or more displays.

[0056] When all of the one or more images indicating the one or more display contents selected as candidates cannot be arranged on the one or more displays (No in step S5), the display content selection unit 14 changes the one or more display contents selected as candidates (step S6). For example, the display content selection unit 14 changes to one or more display contents excluding the display content with the lowest priority among the one or more display contents selected in step S4.

[0057] When all of the one or more images indicating the one or more display contents selected as candidates can be arranged on the one or more displays (Yes in step S5), the display content selection unit 14 selects the one or more display contents selected as candidates as the one or more display contents to be displayed on the one or more displays (step S7).

[0058] In this way, when the display content selection unit 14 can select one or more pieces of display content as candidates and arrange all of the one or more images indicating the one or more pieces of display content selected as candidates on one or more displays, the one or more pieces of display content selected as candidates are selected as one or more pieces of display content to be displayed on one or more displays (display content selection step) (steps S4 to S7).

[0059] The display position determination unit 17 determines the display position of each of the one or more pieces of display content based on the allowable degree of display position change set for each of the plurality of pieces of display content (display position determination step) (step S8). Specifically, the display position determination unit 17 determines, based on the allowable degree of display position change set for each of the plurality of pieces of display content, the display position on one or more displays other than the failed display among the plurality of displays 1a to 1d such that the displacement with respect to the position where the same piece of display content was displayed before the failed display was detected is smaller starting from the piece of display content with a lower allowable degree among the one or more pieces of display content.

[0060] The display switching unit 18 displays each of the one or more pieces of display content at the display position of the display content (display switching step) (step S9), and ends the process.

[0061] FIG. 4 is a flowchart showing an example of the operation in step S4 of FIG. 3. Next, with reference to FIG. 4, an example of the operation in step S4 of FIG. 3 will be described.

[0062] As shown in FIG. 4, the display content selection unit 14 acquires the area of the display region of one or more displays (step S11). For example, the area of each display region of the plurality of displays 1a to 1d is stored in advance, such as being input to the display control device 10.

[0063] The display content selection unit 14 acquires the areas of one or more images indicating one or more display contents (step S12). For example, the display content selection unit 14 acquires the area of each of one or more images indicating one or more display contents from image data or the like for forming each of one or more images indicating one or more display contents. Note that step S12 may be performed before step S11.

[0064] The display content selection unit 14 selects, as candidates, one or more display contents such that the areas of one or more images indicating one or more display contents are equal to or less than the area of the display region of one or more displays (step S13), and ends the process.

[0065] FIG. 5 is a flowchart showing an example of the operation in step S8 of FIG. 3. Next, with reference to FIG. 5, an example of the operation in step S8 of FIG. 3 will be described.

[0066] As shown in FIG. 5, the display position determination unit 17 determines whether there is any display content among one or more display contents for which the display position has not been determined (step S21).

[0067] If there is any display content among one or more display contents for which the display position has not been determined (Yes in step S21), the display position determination unit 17 determines the position of the display content with the lowest tolerance among the display contents for which the display position has not been determined (step S22). Specifically, the display position determination unit 17 determines the display position of the display content such that the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller.

[0068] If there is no display content among one or more display contents for which the display position has not been determined (No in step S21), the display position determination unit 17 ends the process.

[0069] FIG. 6 is a first explanatory diagram for explaining an example of the operations shown in FIGS. 4 and 5. FIG. 7 is a second explanatory diagram for explaining an example of the operations shown in FIGS. 4 and 5. FIG. 8 is a table showing an example of priorities and tolerances. Next, with reference to FIGS. 7 to 9, an example of the operations shown in FIGS. 4 and 5 will be described.

[0070] As shown in FIG. 6(a), when the display 1c malfunctions, the failure detection unit 11 detects the display 1c as a failed display.

[0071] As shown in FIG. 7(a), when a failed display is detected, the display content selection unit 14 acquires the areas of the display regions of one or more displays 1a, 1b, 1d. Also, as shown in FIG. 7(b), the display content selection unit 14 acquires the area of each of a plurality of images showing a plurality of display contents. Here, as shown in FIG. 8, priorities and tolerances are set. The smaller the number, the higher the priority. Also, the smaller the number, the lower the tolerance. Returning to FIG. 7, the display content selection unit 14 determines one or more display contents such that the area of one or more images is less than or equal to the area of the display regions of one or more displays 1a, 1b, 1d. Since the area of one or more displays 1a, 1b, 1d is 22, the display content selection unit 14 selects six display contents (contents of an image taken of the rear right side of the vehicle, contents of an image taken of the rear left side of the vehicle, contents related to the speedometer, contents related to the odometer, contents related to the fuel gauge, and contents related to the air conditioner) with higher priorities such that the area is 22 or less.

[0072] As shown in FIG. 6(b), the display position determination unit 17 determines the display positions on one or more displays 1a, 1b, 1d such that the displacement with respect to the position where the same display content was displayed before the failed display was detected is smaller from the image showing the display content with a lower tolerance among one or more images.

[0073] First, the display position determination unit 17 determines the position of the image showing the content captured at the right rear with the lowest tolerance such that the displacement with respect to the position (display 1c) where the image showing the same display content was displayed before the failure is smaller. The position is determined to be the position where the image showing the content related to the odometer and the image showing the content related to the speedometer are displayed on display 1a. Also, the display position determination unit 17 determines the position of the image showing the content related to the left rear with the lowest tolerance such that the displacement with respect to the position (display 1d) where the image showing the same display content was displayed before the failure is minimized. The position is determined to be on display 1d. Next, the display position determination unit 17 determines the position of the image showing the content related to the speedometer with the second lowest tolerance such that the displacement with respect to the position where the image showing the same display content was displayed before the failure is smaller. The position is determined to be the position where the image showing the content related to the fuel gauge is displayed on display 1a. Similarly, the display position determination unit 17 determines the positions of the images showing the content related to the odometer, the fuel gauge, and the air conditioner in this order.

[0074] The display switching unit 18 causes the six images showing the six display contents to be displayed at the determined positions, thereby displaying the six display contents on one or more of displays 1a, 1b, and 1d. When display 1c is restored, the display switching unit 18 causes each of the plurality of display contents to be displayed at the position where it was displayed before the failure display was detected, as shown in Fig. 6(a).

[0075] Fig. 9 is a third explanatory diagram for explaining an example of the operations shown in Figs. 4 and 5. Fig. 10 is a fourth explanatory diagram for explaining an example of the operations shown in Figs. 4 and 5. Fig. 11 is a table showing another example of priorities and tolerances. Next, with reference to Figs. 8 to 11, an example of the operations shown in Figs. 4 and 5 will be described.

[0076] Here, as shown in FIG. 11, priorities and tolerances are set. Also, for each of a plurality of display contents, in addition to the area of the image (original area) that displayed the display content before a failure display was detected, the minimum value of the area that can be reduced (reducible area) when the image is reduced and displayed is stored. The image may be reduced to any area as long as the area is equal to or larger than the reducible area. In other words, the image is not reduced when the area becomes less than the reducible area.

[0077] As shown in FIG. 9(a), when the display 1c fails, the failure detection unit 11 detects the display 1c as a failure display.

[0078] As shown in Fig. 10(a), when a failure display is detected, the display content selection unit 14 acquires the areas of the display regions of one or more displays 1a, 1b, 1d. Also, as shown in Fig. 10(b), the display content selection unit 14 acquires the area of each of a plurality of images showing a plurality of display contents. Here, for the images showing each of the three display contents with lower priority (contents related to radio, contents related to navigation, and contents related to air conditioner), they are reducible (see Fig. 11), and the size of the reduced image, which is smaller than the image showing the same content before the failure display was detected, is acquired. The display content selection unit 14 determines one or more display contents so that the area of one or more images including the reduced image is less than or equal to the area of the display regions of one or more displays 1a, 1b, 1d. Note that when the reduced image of the target image is less than the reducible area, the display content selection unit 14 determines that the target image will not be displayed as a reduced image. Here, since the area of one or more displays 1a, 1b, 1d is 22, the display content selection unit 14 selects eight display contents with higher priority (contents of a rear right view of the vehicle, contents of a rear left view of the vehicle, contents related to the speedometer, contents related to the odometer, contents related to the fuel gauge, contents related to the air conditioner, contents related to navigation, and contents related to radio) so that the area becomes 22 or less. Note that the image showing the contents related to radio may not be included in one or more images, and the image showing the contents related to the air conditioner or the image showing the contents related to navigation may be displayed slightly larger.

[0079] As shown in Fig. 9(b), the display position determination unit 17 determines the display positions on one or more displays 1a, 1b, 1d so that the displacement with respect to the position where the same display content was displayed before the failure display was detected is smaller, from the images showing the display contents with lower tolerance among one or more images.

[0080] Here, the display position determination unit 17 determines the positions of each of the three images indicating the display contents with lower priorities such that the displacement with respect to the position where the images indicating the same contents were displayed before the failure is smaller, to the position where the image indicating the content related to radio in the display 1b is displayed. The display position determination unit 17 determines the positions of each of the three images such that the three images are arranged vertically.

[0081] The display switching unit 18 causes the eight images indicating the eight display contents to be displayed at the determined positions, thereby displaying the eight display contents on one or more of the displays 1a, 1b, and 1d. When the display 1c is restored, the display switching unit 18, as shown in Fig. 9(a), causes each of the plurality of display contents to be displayed at the position where it was displayed before the failed display was detected.

[0082] In addition, for each of the plurality of display contents, if there is an alternative image for the image that indicated the display content before the failed display was detected, the area of the alternative image may be stored. In this case, for example, the display content selection unit 14 acquires the area of the alternative image for the display content with an alternative image, and determines one or more display contents such that the area of one or more images including the alternative image is less than or equal to the area of the display areas of one or more of the displays 1a, 1b, and 1d. The area of the alternative image is different from the area of the image that indicated the same display content before the failed display was detected. If the area of one or more images including the alternative image is not less than or equal to the area of the display areas of one or more of the displays 1a, 1b, and 1d, the display content selection unit 14 does not perform display with the alternative image.

[0083] Also, for each of the plurality of display contents, if there are a reduced image and an alternative image, either one may be preferentially selected, or the smaller one may be selected, or either one may be selected by a predetermined method.

[0084] The display control device 10 according to this embodiment includes a failure detection unit 11 that detects a failed display among a plurality of displays 1a to 1d, and when a failed display is detected, based on the display priorities set for each of the plurality of display contents that were displayed on the plurality of displays 1a to 1d before the failed display was detected, a display content selection unit 14 that selects one or more display contents with higher priorities among the plurality of display contents, and based on the allowable degree of display position change set for each of the plurality of display contents, from the display contents with a lower allowable degree among the one or more display contents, a display position determination unit 17 that determines the display positions on one or more displays other than the failed display among the plurality of displays 1a to 1d so that the displacement with respect to the position where the same display content was displayed before the failed display was detected becomes smaller, and a display switching unit 18 that displays each of the one or more display contents at the display position of the display content.

[0085] According to this, one or more display contents with higher priorities among the plurality of display contents can be selected, and the selected one or more display contents can be displayed on one or more displays other than the failed display. Therefore, when a failed display is detected, the display content that is desired to be preferentially displayed among the plurality of display contents can be easily displayed. Also, the display positions can be determined so that the displacement with respect to the position where the same display content was displayed before the failed display was detected becomes smaller from the display contents with a lower allowable degree among the one or more display contents. Therefore, before and after the detection of the failed display, the displacement of the display positions of the display contents for which it is not desired to change the display positions as much as possible can be easily made smaller. In this way, when a failed display is detected, the display content that is desired to be preferentially displayed among the plurality of display contents can be easily displayed, and the displacement of the display positions of the display contents for which it is not desired to change the display positions as much as possible before and after the detection of the failed display can be easily made smaller.

[0086] Also, in the display control device 10 according to the present embodiment, the display content selection unit 14 selects one or more images indicating one or more display contents, each of which has the same size as the image that showed the same display content before the failure display was detected, such that the area of the one or more images is equal to or less than the area of the display regions of the one or more displays. The display position determination unit 17 determines the positions in the one or more displays such that, for the image indicating the display content with a lower tolerance among the one or more images, the displacement from the position where the image that showed the same display content before the failure display was detected was displayed is smaller, thereby determining the display position of each of the one or more display contents. The display switching unit 18 displays each of the one or more images at the determined position, thereby displaying each of the one or more display contents at the display position of the display content.

[0087] According to this, one or more images indicating one or more display contents, each of which has the same size as the image that showed the same display content before the failure display was detected, can be used to easily select one or more display contents and easily determine the display position of each of the one or more display contents. Therefore, when a failure display is detected, it is possible to more easily display the display content that is desired to be preferentially displayed among the plurality of display contents, and it is possible to more easily make the displacement of the display position of the display content that is not desired to change the display position as much as possible before and after the detection of the failure display smaller.

[0088] Also, in the display control device 10 according to the present embodiment, the display content selection unit 14 selects one or more images indicating one or more display contents, at least one of which is a reduced image reduced from an image that showed the same display content before the failure display was detected or an alternative image of an image that showed the same display content before the failure display was detected, such that the area of the one or more images is equal to or less than the area of the display regions of the one or more displays. The display position determination unit 17 determines the positions in the one or more displays such that, from among the images indicating the display contents with lower tolerance, the displacement with respect to the position where the image that showed the same display content before the failure display was detected was displayed is smaller, thereby determining the display positions of each of the one or more display contents. The display switching unit 18 displays each of the one or more images at the determined positions, thereby displaying each of the one or more display contents at the display positions of the respective display contents.

[0089] According to this, it is possible to easily select one or more display contents using one or more images indicating one or more display contents, at least one of which is a reduced image reduced from an image that showed the same display content before the failure display was detected or an alternative image of an image that showed the same display content before the failure display was detected, and it is possible to easily determine the display positions of each of the one or more display contents. Therefore, when a failure display is detected, it is possible to more easily display the display content that is desired to be preferentially displayed among the plurality of display contents, and it is possible to more easily make the displacement of the display position of the display content that is not desired to change the display position as much as possible before and after the detection of the failure display smaller.

[0090] Also, in the display control device 10 according to the present embodiment, when the failure display is restored, the display switching unit 18 displays each of the plurality of display contents at the positions where they were displayed before the failure display was detected.

[0091] According to this, when the failure display is restored, each of the plurality of display contents can be displayed at the position where it was displayed before the failure display was detected.

[0092] Also, in the display control device 10 according to the present embodiment, the plurality of displays 1a to 1d include a display 1a disposed in front of the driver's seat of the vehicle and displaying two or more of the plurality of display contents, a display 1b disposed in front of the passenger seat of the vehicle and displaying two or more of the plurality of display contents, a display 1c included in the electronic side mirror on the right side of the vehicle and displaying one of the plurality of display contents, and a display 1d included in the electronic side mirror on the left side of the vehicle and displaying one of the plurality of display contents.

[0093] According to this, when a failure display is detected among the display 1a disposed in front of the driver's seat of the vehicle, the display 1b disposed in front of the passenger seat of the vehicle, the display 1c included in the electronic side mirror on the right side of the vehicle, and the display 1d included in the electronic side mirror on the left side of the vehicle, in one or more displays other than the failure display, it is possible to easily display the display content that is preferentially displayed among the plurality of display contents, and it is possible to easily make the displacement of the display position of the display content that is not desired to change the display position as little as possible before and after the detection of the failure display.

[0094] In addition, the display control method according to the present embodiment includes a detection step (step S3) of detecting a failed display among a plurality of displays 1a to 1d, and when the failed display is detected, based on the display priorities set for each of the plurality of display contents displayed on the plurality of displays 1a to 1d before the failed display was detected, a display content selection step (steps S4 to S7) of selecting one or more display contents with higher priorities among the plurality of display contents, and based on the allowable degree of display position change set for each of the plurality of display contents, from the display contents with a lower allowable degree among the one or more display contents, a display position determination step (step S8) of determining the display positions on one or more displays other than the failed display among the plurality of displays 1a to 1d so that the displacement with respect to the position where the same display content was displayed before the failed display was detected becomes smaller, and a display switching step (step S9) of displaying each of the one or more display contents at the display position of the display content.
