Lane Display Aspect Adjustment for Odd-Even Road Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for route guidance information impair visibility due to frequent changes in display position caused by changes in road shape and vehicle position.
Innovation Solution
A display system that adjusts the display aspect of lanes based on whether the road has an odd or even number of lanes, positioning the center lane accordingly and maintaining consistent display aspects during lane changes, using a road shape acquirer, number-of-lanes determiner, and display aspect controller to generate and display images on a HUD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display position of route guidance information is adjusted frequently to match changes in road shape and vehicle position, then the accuracy of route guidance is improved, but the visibility and stability of the displayed image deteriorates
Solution Approach 1:
The patent applies parameter changes by adjusting the display aspect ratio of lanes based on whether the number of lanes is odd or even. When the number of lanes changes, the system modifies the aspect ratio parameter to maintain proper visualization, resolving the contradiction between accurate route guidance and stable image display
Solution Approach 2:
The system dynamically adjusts the display aspect ratio based on real-time lane configuration data. The display controller continuously monitors the number of lanes and modifies the aspect ratio accordingly, enabling the system to adapt to changing road conditions while maintaining stable and visible display output
2Adaptability or versatility
If the display aspect ratio of lanes is adjusted to accommodate changes in the number of lanes, then the adaptability of the display system is improved, but the complexity of the control system increases
Solution Approach 1:
The patent implements adaptability through parameter changes by modifying the display aspect ratio based on the detected number of lanes. The system uses a simple odd/even determination logic to adjust the aspect ratio parameter, achieving high adaptability to different lane configurations without requiring complex control algorithms
Solution Approach 2:
The system applies local quality by making targeted adjustments only to the aspect ratio parameter when lane configuration changes are detected. Rather than redesigning the entire display system, the patent modifies only the necessary local parameter (aspect ratio) to accommodate different lane scenarios, thereby maintaining system simplicity while improving adaptability

AI summary
A display system includes a display configured to display an image, a road shape acquirer configured to acquire a shape of a road around a vehicle, and a display controller configured to cause an image including the road shape acquired by the road shape acquirer to be displayed on the display, and the display controller changes a display aspect of lanes to be displayed on the display, on the basis of whether the number of lanes of the road around the vehicle is an odd number or an even number.
