Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems face challenges in displaying high-quality, seamless images across multiple displays without data transmission delays and maintaining consistent image quality, particularly in advanced driver assistance systems (ADAS) and autonomous driving applications.
Innovation Solution
A vehicle control device and method that generate and synthesize images for multiple displays, such as a head-up display (HUD), cluster, and center information display (CID), dividing the synthesized images to ensure consistent and high-quality visuals across all displays without data transmission delays and image quality discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple displays are used to provide comprehensive driving information, then information completeness is improved, but data transmission delays and image quality differences occur
Solution Approach 1:
The system divides the comprehensive driving information into multiple separate image streams, with each image stream containing specific information suitable for particular displays (e.g., critical safety information for HUD, detailed navigation for CID). This segmentation allows each image to be processed and transmitted independently, reducing overall transmission delays while maintaining information completeness across the multi-display system.
2Loss of information
If multiple displays are used to provide comprehensive driving information, then information completeness is improved, but image quality consistency deteriorates
Solution Approach 1:
The system applies different image processing parameters and quality settings to different image streams based on the specific requirements of each display and the type of information being conveyed. Critical safety information displayed on the HUD receives optimized processing for immediate visibility, while less time-sensitive information on the CID can use different quality parameters. This local quality approach maintains consistency within each display's context while accommodating the diverse requirements of the multi-display system.
3Adaptability or versatility
If separate controllers generate images for multiple displays, then display independence is improved, but system complexity increases
Solution Approach 1:
The system merges the image generation functions into a single centralized controller that produces all image streams. This unified approach reduces system complexity by eliminating multiple separate controllers while maintaining display independence through the segmentation of image content. The single controller coordinates all displays, ensuring consistent timing and quality standards across the system.
