Vehicle Display Control for Lane Marking Attention Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane change assistance systems fail to inform drivers why attention is not called when approaching a lane marking, leading to uncertainty about the satisfaction of predetermined conditions.
Innovation Solution
A vehicle display control system that displays lane markings in different styles based on whether predetermined conditions for attention are satisfied, including varying display intensity and adding warning images when necessary, to inform drivers about the reason for attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays lane marking images in uniform style regardless of condition, then the display system is simple, but the driver cannot comprehend whether predetermined conditions are satisfied
Solution Approach 1:
The patent applies local quality by varying the display style of lane marking images based on the satisfaction of predetermined conditions. When conditions are satisfied, the system displays enhanced visual information (e.g., different colors, patterns, or brightness) to indicate that calling attention should occur. This localized variation in display quality provides the driver with information about condition satisfaction without requiring a completely different display system.
Solution Approach 2:
The patent utilizes color changes as a specific implementation of visual variation. By changing the color or visual characteristics of lane marking images based on condition satisfaction, the system communicates status information to the driver. For example, different colors may indicate whether the vehicle is approaching a lane marking at a speed that requires driver attention, providing intuitive feedback without complex additional hardware.
2Loss of information
If the system provides detailed information about condition satisfaction, then driver comprehension improves, but the information processing complexity increases
Solution Approach 1:
The patent segments the information presentation by separating the display of lane marking images from additional information about condition satisfaction. The system first displays the basic lane marking image, and then selectively adds or modifies visual information based on whether predetermined conditions are met. This segmentation allows the system to provide detailed information when needed while maintaining simplicity when conditions are not satisfied.
Solution Approach 2:
The patent applies partial action by providing additional information about condition satisfaction only when necessary - specifically when the vehicle is approaching a lane marking and the driver needs to understand why attention is or is not being called. The system does not continuously display all possible information, but rather provides partial information (just the relevant condition status) to avoid unnecessary processing complexity while still improving driver comprehension when needed.
Data Source
AI summary
A vehicle display control device includes a processor. The processor detects a lane marking in an object lane in which a vehicle is traveling. When the vehicle is approaching the lane marking, the processor displays a lane marking image representing the lane marking in different display styles depending on whether a predetermined condition for calling attention is satisfied or not.
