And the main control apparatus 11 displays the simple information of the information currently displayed on the non-recognition display unit to which the highest priority was given to the specified display unit. For example, in a situation where the driver's line of sight does not overlap the head-up display 13 displaying the blind spot screen, and the driver's line of sight faces the center display 12, the main controller 11 displays the center display 12 on the center display 12. Then, information that simply indicates the contents of the blind spot screen, for example, character information such as “a vehicle is present at the right rear” is displayed.

  • the main control device 11 outputs the name of the non-cognitive display unit to which the highest priority is given from a speaker (not shown) by voice. That is, for example, when the driver's line of sight does not overlap the head-up display 13 displaying the blind spot screen and the driver's line of sight is not directed to any of the other display units 12 and 14, the main control is performed.

  • the main control device 11 may be configured to execute either one of the guidance processes B and C.
  • the driver when the driver does not recognize the non-recognized display unit to which the highest priority is given, a guidance process is executed. You can be directed to the display unit with the highest priority. Accordingly, the driver can preferentially recognize the display unit displaying important information to be recognized.
  • the display unit when the driver's line of sight overlaps the display units 12, 13, and 14 in the state of displaying information, the display unit is specified as the cognitive display unit. That is, even if the display unit that does not display information is visually recognized, the driver cannot recognize the information. According to the present embodiment, even when a display unit in a state where information is not displayed is visually recognized by the driver, the display unit can be prevented from being set as a recognition display unit. The displayed information can be surely recognized by the driver.
  • the non-recognizing display unit is specified as the cognitive display unit. That is, by re-setting the non-recognition display unit that is visually recognized by the driver as the recognition processing unit, it is possible to reduce the number of display units to be subjected to the guidance process as needed. Accordingly, it is possible to guide the driver's line of sight one after another to display units that are not visually recognized. Moreover, although it is a display unit which the driver has recognized, it is possible to avoid the waste of guiding the line of sight again to the recognized display unit. In addition, since the display units that are the targets of the guidance process can be successively reduced, the processing load can be gradually reduced.
  • the guidance process is executed when the priority given to the non-recognizing display unit is equal to or higher than a predetermined value. Therefore, by setting a predetermined value in advance in association with the safety of the vehicle occupant, it is possible to preferentially guide the driver's line of sight to the display unit that displays information important for safety.
  • the direction in which the non-recognition display unit to which the highest priority order, in this case, the highest priority order is given exists in the display unit where the driver's line of sight overlaps by the guidance process. Indicated. Accordingly, the driver can smoothly move the line of sight to the non-recognition display unit on which information to be recognized is displayed.
  • the guidance unit displays the display unit on which the driver's line of sight overlaps with the higher priority, in this case, the non-recognition display unit with the highest priority. Simple information is displayed. Therefore, although it is simple, the driver can immediately recognize important information to be recognized.
  • the name of the non-recognition display unit to which the higher priority, in this case the highest priority is given is output by voice by the guidance process.
  • the driver can immediately and audibly recognize which display unit displays the information to be recognized.
  • the line of sight can be smoothly moved to the display unit.
  • the information displayed on the non-recognition display unit to which the highest priority, in this case, the highest priority is given is output by voice by the guidance process.
  • the driver can recognize the information which should be recognized also auditorily. For example, when the vehicle is traveling, it may be difficult for the driver to move the line of sight to the display unit. In such a case, the information that should be recognized can be audibly recognized, and there is no risk of impairing safe driving.
