Vehicle Display Overlay Control for Priority Notification Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display apparatuses interfere with the recognition of important information when notifying the driver of information more critical than obstructions, as the display of obstruction detection ranges can obscure important notifications.
Innovation Solution
A vehicle display control apparatus that uses an obstruction detector to convert obstruction information into a virtual marker image and important information into a notification image, allowing simultaneous display while adjusting the display format to prioritize the notification image's visibility, ensuring the driver recognizes critical information without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the obstruction sensor operates and displays detection range information, then the driver can understand the detection range, but the display interferes with the recognition of important notification information
Solution Approach 1:
The display controller dynamically adjusts the display format of the virtual marker image based on the presence of notification information. When notification information is detected, the system automatically changes the display format (e.g., from solid to dotted lines, or reduces brightness) to reduce interference. This dynamic adaptation resolves the contradiction by making the display system flexible rather than static.
Solution Approach 2:
The system changes display parameters such as line style, color, or transparency of the virtual marker image when notification information is present. These parameter changes allow the obstruction detection range to remain visible while reducing its visual dominance, thereby preventing interference with important notifications while maintaining situational awareness.
2Loss of information
If the display shows both obstruction information and notification information simultaneously, then comprehensive information is provided, but the important notification information may be obscured
Solution Approach 1:
The display controller applies different visual qualities to different regions of the display based on information importance. The notification information region receives enhanced visual treatment (higher contrast, brightness, or prominence) while the obstruction detection range receives reduced visual treatment. This local differentiation ensures that important information stands out without completely hiding other relevant information.
Solution Approach 2:
The display format changes dynamically based on the priority and presence of different information types. When high-priority notification information appears, the system automatically adjusts the visual properties of concurrent obstruction information to maintain visibility hierarchy. This dynamic reconfiguration allows comprehensive information display while preventing obscuration of critical notifications.

AI summary
A display controller converts a detection target region contained within a detection range of an obstruction sensor group and extending from a vehicle to the periphery thereof into a virtual marker image and causes a virtual image to be displayed by superimposing the image over a scene in front of the vehicle. When the relative position of an obstruction is within the detection target region, the display controller causes an arc-shaped ripple spreading in a direction based on the relative position of the obstruction to be displayed in a region, of the virtual marker image, located in a direction based on the relative position of the obstruction. The display controller converts the important information into a notification image and causes the notification image to be displayed in a display medium. The display controller changes the display format of at least one of the virtual marker image or the notification image.
