Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle assistance technologies, such as HUD and augmented reality interfaces, primarily provide simple display or alarming information from vision sensors, lacking comprehensive driving-related guides that effectively assist drivers in preventing accidents and enhancing safety.
Innovation Solution
An electronic apparatus and method that generates and displays a driving-related guide on a specific region of an augmented reality road guide screen, including indicators for lane departure, forward vehicle collision prevention, signal change, and lane change guides, using information like signal type, line position, distance to other vehicles, and route information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple display or alarming information is provided from vision sensors, then device complexity is reduced, but driving assistance effectiveness deteriorates
Solution Approach 1:
The system segments driving assistance into multiple specialized modules: lane departure guide module, forward vehicle collision prevention module, signal change guide module, and lane change guide module. Each module processes specific aspects of driving safety independently, then integrates their outputs to provide comprehensive guidance without requiring a single complex system.
Solution Approach 2:
The patent transitions from traditional 2D display to 3D spatial positioning of guidance indicators on the road surface. By projecting virtual indicators into the third dimension (spatial location on road), the system provides more intuitive and effective driving assistance while maintaining manageable system complexity through software-based rendering.
2Reliability
If comprehensive driving-related guides are provided, then driving safety is improved, but information processing complexity increases
Solution Approach 1:
The vision sensor system is designed to perform multiple functions simultaneously: detecting lane markings, identifying forward vehicles, recognizing traffic signals, and determining road geometry. This multi-functional approach consolidates what would otherwise require separate sensors, reducing overall system complexity while providing comprehensive driving safety guidance.
Solution Approach 2:
The system performs preliminary processing of vision sensor data to extract essential driving parameters (lane position, vehicle distance, signal state) before generating guidance indicators. By pre-processing and structuring the data in advance, the system reduces the computational complexity required during real-time guidance generation.
3Loss of information
If multiple types of driving guides are displayed, then situational awareness is enhanced, but display complexity increases
Solution Approach 1:
Different types of driving guidance information are displayed at specific locations corresponding to their relevance: lane departure guides appear at lane boundaries, forward vehicle collision prevention indicators appear near the detected vehicle, signal change guides appear at intersection locations. This spatial organization reduces display complexity by placing each type of information where it is most contextually appropriate.
Solution Approach 2:
The system merges multiple guidance indicators into a unified visual display overlaid on the road view. By combining lane guides, collision prevention indicators, signal guides, and lane change guides into a single integrated display layer, the system enhances situational awareness while managing display complexity through unified rendering rather than separate displays.
