Vehicle Information Display Relocation Under Adverse Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driver assistance technologies face challenges in ensuring optimal visibility of vehicle information on displays like outside rear-view mirrors and transparent heads-up displays due to adverse conditions such as glare, weather, and user mobility, which can impede the user's perception of critical information.
Innovation Solution
A system utilizing sensors, cameras, and AI or ML algorithms to detect adverse visibility conditions and dynamically reposition vehicle information from a default display to an additional secondary location, such as an infotainment display or instrument panel, to maintain user awareness of vital information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle information is displayed in a default location (outside rear-view mirror or TD-HUD), then the display is compact and integrated, but visibility deteriorates under adverse conditions such as glare, weather, or user mobility issues
Solution Approach 1:
The system dynamically switches the display location of vehicle information between the default location (outside rear-view mirror or TD-HUD) and an alternative location (instrument panel or infotainment display) based on detected adverse visibility conditions. This dynamic adaptation ensures information remains visible regardless of environmental factors such as glare, weather, or user mobility issues.
Solution Approach 2:
The system introduces an intermediary display mechanism that provides an alternative path for information delivery. When the primary display location becomes unreliable due to adverse conditions, the information is routed through a secondary display location, ensuring continuous visibility and maintaining the reliability of critical vehicle information.
2Reliability
If vehicle information is displayed on multiple display locations, then visibility reliability improves under adverse conditions, but device complexity increases
Solution Approach 1:
The display system is designed with multi-functionality, where the same vehicle information can be displayed across multiple locations (outside rear-view mirror, TD-HUD, instrument panel, or infotainment display). This universal display capability allows the system to maintain reliability by switching locations without requiring entirely separate systems for each display point.
Solution Approach 2:
The system employs dynamic switching logic that activates multiple display locations only when adverse visibility conditions are detected. During normal conditions, information is displayed solely in the default location, maintaining simplicity. When glare, weather, or mobility issues are detected, the system dynamically adds alternative display locations to ensure visibility.
Data Source
AI summary
A system and method transmits a first signal to display vehicle information in a default location of a vehicle upon an occurrence of a condition, receives data indicative of an adverse visibility condition causing suboptimal perception of the vehicle information in the default location, and transmits a second signal to display the vehicle information in a secondary location.
