Display control device and non-transitory computer-readable storage medium for display control on head-up display

A display control device for a vehicle to control a display on a head-up display, the display control device comprising:

• a control information acquisition unit that acquires driving control information related to a driving control of the vehicle, from a lane keeping control unit that controls an in-lane traveling of the vehicle to cause the vehicle to travel in a lane;
• a change information acquisition unit that acquires lane change information related to a lane change of the vehicle, from a lane change control unit that controls the lane change of the vehicle;
• and
• a display control unit that displays an estimated trajectory content indicating an estimated trajectory of the in-lane traveling to be superimposed on a road surface as a superimposition target, based on the driving control information, wherein
• in response to acquiring the lane change information during the in-lane traveling, the display control unit begins to display a lane change content indicating an estimated trajectory of the lane change based on the lane change information, after terminating display of the estimated trajectory content.

A display control device for a vehicle to control a display on a head-up display, the display control device comprising:

• a change information acquisition unit that acquires lane change information related to a lane change of the vehicle, from a lane change control unit that controls the lane change of the vehicle;
• and
• a display control unit that displays a lane change content indicating an estimated trajectory of the lane change to be superimposed on a road surface as a superimposition target, based on the lane change information, in response to acquiring the lane change information, wherein
• when an execution section of the lane change by the lane change control unit is within an angle of view of the head-up display, the display control unit displays the lane change content to be superimposed on the road surface including at least a part of the execution section, and
• when the execution section is outside the angle of view, the display control unit displays a change standby content indicating that the lane change is to be performed in a mode different from the lane change content that is displayed when the execution section is within the angle of view.

A non-transitory computer-readable storage medium which stores program instructions for controlling a head-up display of a vehicle, the program instructions configured to cause one or more processors to:

• acquire driving control information related to a driving control of the vehicle, from a lane keeping control unit that controls an in-lane traveling of the vehicle to cause the vehicle to travel in a lane;
• display an estimated trajectory content indicating an estimated trajectory of the in-lane traveling to be superimposed on a road surface as a superimposition target, based on the driving control information;
• acquire lane change information related to a lane change of the vehicle from a lane change control unit that control the lane change of the vehicle;
• and
• in response to acquiring the lane change information during the in-lane traveling, display a lane change content indicating an estimated trajectory of the lane change together with the estimated trajectory content, based on the lane change information.
