  • control unit 25 acquires speed information of the vehicle 1 (STEP 21).
  • the control unit 25 acquires speed information, for example, at predetermined time intervals.
  • the control unit 25 determines whether the vehicle speed V is greater than or equal to the threshold value Vth (STEP 22). If it is determined that the vehicle speed V is less than the threshold value Vth (NO in STEP 22), the control unit 25 does not change the display positions of the information I1 and I2.
  • the threshold Vth can be appropriately set, for example, based on the speed of the vehicle at which the focal position of the occupant is assumed to be farther than the display distance of the virtual image object Ia. For example, the threshold Vth is 60 km/h.
  • the control unit 25 determines whether or not an instruction from the occupant of the vehicle 1 has been obtained (STEP 23). For example, the control unit 25 notifies the occupant of the vehicle 1 that the information displayed in the virtual image object Ia will be displayed in the virtual image object Ib. The notification may be displayed on the virtual image object Ib, or may be notified by an audio output device or the like arranged in the vehicle 1 . For example, if the occupant does not wish to change the display position of the information displayed on the virtual image object Ia, the occupant instructs to that effect via the voice input device 30 arranged in the vehicle 1 .
  • control unit 25 When it is determined that the command from the passenger of the vehicle 1 has been acquired (YES in STEP 23), the control unit 25 does not change the display positions of the information displayed on the virtual image objects Ia and Ib. If there is no command from the occupant within a predetermined period of time after the display position change notification (NO in STEP 23), the control unit 25 outputs a control signal for displaying the information displayed on the virtual image object Ia on the virtual image object Ib. is output to the image generator 24 (STEP 24).
  • the display position of the information displayed in the virtual image object Ia is changed when there is no instruction from the passenger.
  • the display position may be changed.
  • the positions and ranges of the information displayed on the virtual image objects Ia and Ib are not limited to the forms shown in FIGS. 4, 5, 7, and 9-11.
  • the information I1 displayed in the virtual image object Ia is displayed in the virtual image object Ib based on the speed information of the vehicle 1, the position information of the vehicle 1, or the remaining amount of fuel information of the vehicle 1.
  • the information I1 displayed in the virtual image object Ia may be displayed in the virtual image object Ib based on the information related to the traveling of the vehicle different from these information.
  • the information I2 displayed on the virtual image object Ib is displayed on the virtual image object Ia based on the target object information.
  • the information I2 displayed in the virtual image object Ib may be displayed in the virtual image object Ia based on the information related to the running of the vehicle, which is different from the target object information.
  • the light for generating the virtual image object Ia and the light for generating the virtual image object Ib are emitted from one image generation unit 24 .
  • the HUD 20 includes a plurality of image generators, and can be configured such that the light for generating the virtual image object Ia and the light for generating the virtual image object Ib are emitted from different image generators.
