Vehicle Display Content Control Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling display content in vehicles do not adequately consider additional influencing factors such as passenger states and geographic conditions, leading to potential driver distraction and safety issues during varying degrees of automation.
Innovation Solution
A method and device that detect additional state variables like geodata, user interaction, and driver conditions to dynamically adjust display content on vehicle output means, ensuring appropriate content is displayed based on the degree of automation, geographic conditions, and passenger interactions, thereby enhancing driver attention and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display content is approved based only on degree of automation, then the control system is simple, but driver distraction and safety issues occur due to not considering passenger states and geographic conditions
Solution Approach 1:
The control system segments the approval decision into multiple independent evaluation dimensions: degree of automation level, geographic conditions, driver state, and passenger state. Each dimension is assessed separately and combined to determine final display content approval, allowing comprehensive safety consideration without requiring a monolithic complex system
Solution Approach 2:
The system dynamically adjusts display content approval by continuously monitoring changing conditions such as automation level transitions, geographic location changes, driver state variations, and passenger interactions. The approval status is not static but adapts in real-time as conditions change, optimizing safety while maintaining system manageability
2Adaptability or versatility
If more display content is approved during automated driving, then passenger entertainment is improved, but driver attention may be compromised
Solution Approach 1:
The system applies different approval criteria to different output means based on their location and function. Displays directed at or accessible to the driver receive stricter approval criteria, while displays for passengers receive more lenient criteria. This localized quality control allows versatile content delivery while protecting driver attention through differentiated approval standards
3Reliability
If display content is limited during critical driving situations, then driver attention is maintained, but passenger entertainment options are reduced
Solution Approach 1:
The system introduces an intermediary evaluation layer that assesses the interaction between driver state, geographic conditions, and requested display content. This intermediary mechanism determines whether content approval should be restricted, blocked, or permitted, enabling nuanced control that maintains driver focus while preserving passenger entertainment options where safe

AI summary
Content on a display of a vehicle is controlled based on a degree of automation of a driving state of the vehicle and at least one further state variable of the vehicle or of a passenger.
