Vehicle HUD Navigation Display Switching for Clearer Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-up display systems for vehicles, users may misunderstand navigation guidance due to sudden switches between different navigation images, impairing convenience, especially when the angle of view is limited.
Innovation Solution
A display control device and method that generates non-superimposed content with the same meaning as superimposed content and displays it before switching to superimposed content, ensuring the content is visible within the vehicle's view angle, thereby reducing user misunderstanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If superimposed navigation guide images are displayed directly when distance to intersection is less than predetermined distance, then navigation information can be provided, but user misunderstanding occurs due to sudden switching between different navigation images
Solution Approach 1:
The system displays non-superimposed navigation guide images before switching to superimposed images. This preliminary display action allows users to understand the navigation information in advance without the complexity of superimposed images, preventing sudden switches that cause misunderstanding while ensuring accurate navigation guidance is provided.
2Loss of time
If navigation information is displayed early with limited view angle, then timely guidance can be provided, but information clarity is reduced due to restricted visibility
Solution Approach 1:
The system adapts the display quality and type based on the current view angle conditions. When the view angle is limited, non-superimposed images are displayed with optimized characteristics suitable for restricted visibility. As the view angle expands, the system transitions to superimposed images that provide enhanced information clarity, thus maintaining both timely response and information clarity across different viewing conditions.

AI summary
When the display is controlled by the head-up display used in the vehicle, prior to the display of the superimposed contents to be superimposed and displayed on the specific superimposed object existing in the foreground of the vehicle, the non-superimposed content which has substantially the same meaning as the superposed content to be superimposed and displayed on the foreground in a non-superimposed state on the superimposed object is superimposed and displayed on the foreground.
