Necessary devices may be appropriately added according to the contents to be displayed on the monitor.

(Monitors M1 to M6)
The monitors M1 to M6 are provided in the host vehicle 20 and display predetermined information (for example, information acquired by the camera 13, the position information acquisition unit 14, various sensors 15, and the like).

(Example of arrangement of monitors M1 to M6)

  In this embodiment, the case where six monitors M1 to M6 are provided in the host vehicle 20 is described as an example. However, the present invention is not limited to this, and an arbitrary number of two or more monitors is provided. What is necessary is just to be provided.

(Monitor control device 10)
The monitor control device 10 displays information acquired by the camera 13, the position information acquisition unit 14, and the various sensors 15 on the monitors M1 to M6. Furthermore, when the monitor control device 10 detects a failure of the monitors M1 to M6, the monitor control device 10 displays information to be displayed on the failed monitor on another monitor that has not failed.

  Specifically, the monitor control device 10 includes a monitor control unit 11 and a failure detection unit 12. The monitor control unit 11 may include a storage unit. In addition, the configuration is not limited thereto, and the monitor control unit 11 may be configured to have a separate storage unit.

  The failure detection unit 12 is a unit that detects each failure of the monitors M1 to M6. There are various failure detection methods. For example, the failure detection unit 12 periodically transmits a request signal to each of the monitors M1 to M6, and the failure is detected depending on whether there is a response from each of the monitors M1 to M6. Done. Of course, a monitor that does not need to detect a failure may be excluded from the failure detection target.

  The monitor control unit 11 causes the monitors M1 to M6 to display information acquired from an external device such as the camera 13 in a normal state where no failure is detected. Further, when a failure is detected in any one of the monitors M1 to M6 by the failure detection unit 12, the monitor control unit 11 sets a part or all of information to be displayed on the failed monitor to the failed monitor. Display on the nearest monitor (hereinafter also referred to as alternative monitor).

  For example, when a failure of the monitor M1 is detected by the failure detection unit 12, the monitor control unit 11 displays information such as the vehicle speed, the engine speed, and the remaining amount of fuel to be displayed on the failed monitor M1. Is displayed on the monitor M3 closest to. Accordingly, the driver can grasp information to be displayed on the failed monitor M1 while minimizing a change in line of sight before and after the monitor failure.

  The setting of the monitor closest to the failed monitor will be specifically described. The monitor closest to the failed monitor is, for example, a monitor having a center position with the shortest linear distance from the center position of the failure monitor on the X, Y, and Z axes shown in FIG.

  The monitor that is closest to the failed monitor is set by previously storing a table that defines the correspondence between each monitor and its alternative monitor in the storage unit of the monitor control device 10 and referring to the table. Also good. For example, when the monitor closest to the monitor M1 is the monitor M2, the correspondence relationship that the alternative monitor when the monitor M1 breaks down is the monitor M2 is determined as a table, and the alternative monitor is referred to by referring to the table. It may be set.

  Furthermore, instead of storing a table that defines the correspondence relationship in advance, a table that defines the correspondence relationship may be created by an image processing technique using a camera. For example, a camera is installed above the driver's seating position. This camera is connected to the monitor control device 10. The monitor control device 10 outputs test signals to the monitors M1 to M6, and displays test images such as numbers 1 to 6 on the monitors M1 to M6, respectively. The camera shoots the monitors M1 to M6 on which 1 to 6 are displayed, and the monitor control device 10 displays test images such as numbers 1 to 6 by pattern matching and triangulation using luminance values and the like. The positions of the monitors M1 to M6 are analyzed. By this analysis, the positional relationship between the monitors M1 to M6 can be grasped, and a table that defines the correspondence between the failure monitor and the alternative monitor can be created. By referring to this table, the monitor closest to the failure monitor can be specified. Note that the above-described camera is preferably a twin-lens camera in order to measure positions in the three axes of the X axis, the Y axis, and the Z axis shown in FIG. According to this configuration, the monitor closest to the failed monitor can be identified even if the monitor mounting position or display position is not fixed but varies.

  The monitor control unit 11 may display only a part of information to be displayed on the failure monitor on the alternative monitor. For example, the monitor control unit 11 may cause the monitor M3 to display only speed information having a high degree of importance among information to be displayed on the failed monitor M1.

  The monitor control unit 11 controls the display format of the alternative monitor according to the failure monitor. In other words, the monitor control unit 11 controls the display format of the alternative monitor according to which of the monitors M1 to M6 has failed.

  For example, when the monitor M1 breaks down, the monitor control unit 11 in the monitor M3 closest to the monitor M1 displays information (video information) displayed on the monitor M3 from the beginning and information to be displayed on the failed monitor M1 (video information) Speed information, etc.) are superimposed and displayed.

  For example, when the monitor M4 breaks down, the monitor control unit 11 uses the monitor M5 closest to the monitor M4 to display the information (position information and surrounding information of the own vehicle 20) displayed on the monitor M5 from the beginning, and the failed monitor. Information to be displayed on M4 (video information) is displayed separately.

  Specifically, combinations of each monitor and the display format of information displayed on the monitor are stored in advance in the storage unit of the monitor control device 10 as a table. Based on this table, the monitor control unit 11 may change the display format.

  The monitor control unit 11 may control the display format of the alternative monitor according to the alternative monitor as well as the failure monitor. In other words, the monitor control unit 11 displays the display format of the alternative monitor according to which monitor of the monitors M1 to M6 displays an alternative display as well as which of the monitors M1 to M6 has failed. May be controlled.

  Specifically, combinations of the failure monitor, the alternative monitor, and the display format are stored in advance in the storage unit of the monitor control device 10 as a table. Based on this table, the monitor control unit 11 may change the display format.

  Furthermore, the monitor control unit 11 is not limited to the configuration for controlling the display format of the alternative monitor according to the failure monitor or the alternative monitor, but the type of information to be displayed on the fault monitor or the type of information displayed on the alternative monitor. The display format of the alternative monitor may be controlled accordingly.

  For example, when the monitor M1 fails, the monitor control unit 11 checks the type of information to be displayed on the failed monitor M1 and the type of information displayed from the beginning on the monitor M3 closest to the monitor M1. . Here, the type of information to be displayed on the failed monitor M1 is character information such as speed information, and the type of information displayed on the monitor M3 from the beginning is video information captured by the camera 13a. . For this reason, the monitor control unit 11 determines that there is a low possibility of confusion with these, and displays them in a superimposed manner.

  For example, when the monitor M4 fails, the monitor control unit 11 checks the type of information to be displayed on the failed monitor M4 and the type of information displayed on the monitor M5 closest to the monitor M4. Here, the type of information to be displayed on the failed monitor M4 is video information captured by the camera 13b, and the type of information displayed on the monitor M5 from the beginning is map information. Therefore, the monitor control unit 11 determines that there is a high possibility that they will be confused, and displays them separately.

  Hereinafter, an embodiment in which the monitor control unit 11 controls the display format of the alternative monitor according to the type of information to be displayed on the failure monitor and the type of information displayed on the alternative monitor will be described more specifically.

  In the storage unit of the monitor control device 10, signals output to the monitors are classified and stored in advance based on the type of information to be displayed. Further, the storage unit of the monitor control device 10 stores the type of information to be displayed on the failure monitor and the combination of the type of information to be displayed on the alternative monitor and the display format in association with each other. And the monitor control part 11 changes a display format based on the correspondence.

  For example, a signal for displaying information such as vehicle speed, engine speed, and remaining amount of fuel is set as type A, and a signal for displaying information such as position information and surrounding information of the host vehicle 20 is set as type B. A signal for displaying the captured video information is classified as type C and stored in the storage unit of the monitor control device 10. Here, it is assumed that a signal classified into the type A is output to the failure monitor and a signal classified into the type C is output to the alternative monitor. In this case, the monitor control unit 11 determines the information (video information) displayed from the beginning on the alternative monitor and the failure from the correspondence relationship between the type A and type C stored in the storage unit and the display format by the combination thereof. Information to be displayed by the monitor (speed information, etc.) is superimposed and displayed. The method for controlling the display format of the alternative monitor according to the failure monitor or the alternative monitor is the same except that the display format is classified according to the type of monitor instead of the type of information.

  If the monitor closest to the failure monitor cannot replace the failure monitor for some reason (such as its own failure), the monitor control unit 11 displays information to be displayed on the failure monitor on the monitor closest to the failure monitor. Let A monitor closer to the failure monitor is selected as an alternative monitor with higher priority.

  For example, when the monitor M1 fails but the monitor M3 cannot replace the monitor M1, the monitor control unit 11 displays information to be displayed on the monitor M1 on the monitor M4 that is the second closest to the monitor M1.

  More specifically, the storage unit of the monitor control device 10 stores a combination of each monitor, the substitute monitor, the substitute monitor, and the nearest monitor in a table. Information that should be displayed on the fault monitor on the monitor closest to the alternative monitor in which the failure is detected based on this table when the fault detection unit 12 cannot detect the fault with the alternative monitor, such as when the fault monitor detects a fault on the alternative monitor. Is displayed. Further, when creating a table in which the correspondence relationship is determined by the above-described image processing technique, the position of each monitor is calculated, and the table is created based on the position.
