HUD Display Positioning for Vehicle Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control devices for HUDs can be annoying for drivers as they superimpose travel direction guides on the view of other paths, potentially obstructing the driver's sightline.
Innovation Solution
A display control device that acquires a vehicle's travel route and sets the display position of guidance displays based on the positional relationship between the current path and other paths to avoid superimposition on visible paths, using a processor to determine optimal display positions relative to the view ahead, thereby reducing annoyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guidance display is superimposed on the travel path to guide the vehicle, then the guidance function is improved, but the driver's sightline is obstructed causing annoyance
Solution Approach 1:
The patent applies local quality by differentiating the display position based on the specific road situation. When the other travel path exists inside the display region, the guidance display is positioned at the travel path side rather than centered, creating a localized adjustment that avoids obstructing the driver's view of the intersecting path while maintaining guidance effectiveness for the current travel path.
2Object-affected harmful factors
If the guidance display is positioned to avoid superimposition on other travel paths, then driver annoyance is reduced, but the guidance display effectiveness may be compromised
Solution Approach 1:
The patent implements dynamics by making the display position adaptive rather than fixed. The processor dynamically determines the optimal display position based on real-time road configuration data, adjusting between center position and travel path side position according to whether other travel paths exist inside or outside the display region, thereby maintaining both visibility and guidance effectiveness under varying conditions.

AI summary
A display control device includes a processor. The processor is configured to acquire a travel route of a vehicle, in a case in which the vehicle, traveling on a travel path, changes a travel direction to another travel path, set a display position of a guidance display that guides the travel direction with respect to a display region of a display unit, on the basis of a positional relationship between the display region and the other travel path, and display the guidance display, the display position of which has been set relative to a view ahead of the vehicle, so as to be superimposed on the display region.
