Vehicle Surroundings Display With Primary-Object Highlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems that position large displays high in front of the driver can obstruct the view through the windshield, limiting visibility of the vehicle's surroundings.
Innovation Solution
A method and display system that classifies objects in the vehicle's surroundings as primary or secondary based on their relevance to the driving situation, depicting primary objects in real form and secondary objects in altered form, allowing the display to be partially transparent to maintain visibility and provide additional information as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large display panel is positioned high in front of the driver to improve readability and information display, then the display visibility and information provision are improved, but the view through the windshield is obstructed, reducing driver visibility of surroundings
Solution Approach 1:
The display panel is divided into multiple zones (first display zone and second display zone) with different transparency characteristics. The first display zone has higher transparency to maintain windshield visibility, while the second display zone has lower transparency for better information display. This segmentation allows simultaneous optimization of both visibility and information provision.
Solution Approach 2:
Different regions of the display panel are assigned different optical properties (transparency levels) based on their functional requirements. The local quality varies across the display surface, with transparency being higher in areas requiring visibility and lower in areas prioritizing information display, thus resolving the contradiction between these two requirements.
2Object-affected harmful factors
If the display panel is made fully transparent to maintain visibility through the windshield, then driver visibility is improved, but the display contrast and information readability deteriorate
Solution Approach 1:
The display panel is segmented into zones with different transparency levels. The second display zone has lower transparency to ensure adequate display contrast and information readability, while the first display zone maintains higher transparency for visibility. This segmentation enables both visibility and readability to be optimized in their respective zones.
Solution Approach 2:
The transparency property is made local rather than uniform across the entire display panel. Each zone's transparency is optimized for its specific function: the second zone prioritizes readability with lower transparency, while the first zone prioritizes visibility with higher transparency, thus resolving the contradiction.
3Loss of information
If all objects in the surroundings are displayed in real form to provide complete information, then information completeness is improved, but driver distraction and cognitive load increase, reducing reaction time to critical events
Solution Approach 1:
Different visual processing qualities are applied to different objects based on their relevance to driving. Primary objects receive full-detail real-form display for complete information, while secondary objects receive simplified altered-form display. This differential approach maintains information completeness for critical objects while reducing distraction from non-critical objects.
Solution Approach 2:
The display system dynamically adjusts the level of detail and processing applied to different objects based on their classification as primary or secondary. This dynamic adaptation allows the system to optimize the balance between information completeness and driver focus in real-time based on driving conditions.

AI summary
An approach is described for representing surroundings of a vehicle, the vehicle being in a specific driving situation, on at least one display panel of the vehicle, wherein the surroundings are captured by at least one exterior camera of the vehicle, wherein a check is made to establish whether or not at least one object in the captured surroundings is relevant to the specific driving situation, wherein at least one object which is relevant to the specific driving situation is classified as at least one primary object and at least one object which is irrelevant to the specific driving situation is classified as at least one secondary object, wherein the display panel is divided into at least one primary zone for the at least one primary object and at least one secondary zone for the at least one secondary object, wherein the at least one primary zone is depicted in real form and the at least one secondary zone is depicted in modified form by means of the at least one display panel.
