Semi-Transparent Driver Assistance Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems overlay additional graphical information onto recorded environmental data, causing parts of the original image to be covered and reducing visibility, which hinders optimal driver support.
Innovation Solution
Displaying both recorded environmental data and graphic additional information semi-transparently, with adjustable transparency levels, allowing both to be visible simultaneously and configurable based on vehicle parameters or environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional graphic information is overlaid on recorded environmental data, then driver support is enhanced, but visibility of the original image is reduced
Solution Approach 1:
The patent applies transparency adjustments to the additional graphic information, allowing it to be displayed with varying degrees of opacity. This enables the original environmental image to remain visible while still presenting the additional information, thus resolving the contradiction between enhancing driver support and maintaining image visibility.
Solution Approach 2:
The system dynamically adjusts the transparency of overlay elements based on driving conditions, such as speed, ambient light, and situation complexity. This dynamic adaptation ensures optimal visibility of both the original image and additional information across different operating scenarios, preventing information loss while maintaining effective driver support.
2Measurement precision
If additional information is displayed in large size, then recognizability is improved, but coverage of the original image increases
Solution Approach 1:
By adjusting the transparency of additional information elements, the system allows larger text and graphics to be displayed without completely blocking the original image. The transparency parameter enables both large recognizable information and visible environmental data to coexist on the display.
Solution Approach 2:
The system applies different transparency levels to different regions of the display based on local requirements. Critical areas of the original image maintain higher visibility while less critical areas can have more opaque overlays, optimizing both information recognizability and environmental visibility in their respective zones.
