  • Publication number: 20220016980
    Abstract: In a display control device for a head-up display of a vehicle, a schedule notification content indicating a fulfillment schedule of a lane change is displayed on a road surface in a foreground in a superimposing manner. When the schedule notification content overreaches an angle of view, a non-superimposition content indicating the fulfillment schedule of the lane change independent of a superimposition target may be displayed, or the schedule notification content may be hidden. In a case where an arrow-shaped schedule notification content, having a tip portion indicating an adjacent lane as a destination of the lane change, is displayed in a superimposing manner on a road surface in the foreground, when the tip portion of the schedule notification content in a reference shape overreaches the angle of view, the schedule notification content may be transformed so that the tip portion is positioned within the angle of view.

  • Publication number: 20220018678
    Abstract: In a display control device for a head-up display of a vehicle, it is determined whether a lane change control unit is in a standby state waiting for a lane change of the vehicle. When it is determined that the lane change control unit is not in the standby state, a fulfillment notification content indicating an execution state of the lane change is displayed on a road surface in a foreground in a superimposing manner. When it is determined that the lane change control unit is in the standby state, a standby notification content in a mode different from the fulfillment notification content is displayed on the road surface of the foreground in a superimposing manner, or a standby notification content in a mode associated with the fulfillment notification content is displayed as a non-superimposition content independent of a superimposition target.
