In-Vehicle Distance Display Layout to Prevent Icon Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems can confuse occupants by overlapping icons and bar graphs when inter-vehicle distances change rapidly, leading to inaccurate perception of the situation.
Innovation Solution
An information processing device that dynamically adjusts the position and size of vehicle icons and bar graphs based on inter-vehicle distances to prevent overlap, ensuring clear and accurate representation of the inter-vehicle distance on the in-vehicle display.

Engineering Contradiction Analysis
1Loss of information
If the other vehicle icon is displayed on the front side of the bar graph in the traveling direction, then the inter-vehicle distance information is visually represented, but the icon overlaps with the bar graph when the inter-vehicle distance becomes small, causing occupant confusion
Solution Approach 1:
The display device dynamically adjusts the position and size of the other vehicle icon based on the current inter-vehicle distance. When the distance is large, the icon is displayed at a normal position and size. When the distance becomes small, the icon is automatically repositioned and resized to prevent overlap with the bar graph, thereby maintaining clear information representation without causing occupant confusion
Solution Approach 2:
The system changes the display parameters (position coordinates and size dimensions) of the other vehicle icon according to the detected inter-vehicle distance. By adjusting these parameters in real-time, the system ensures that the icon remains visible and accurate without overlapping the bar graph, resolving the contradiction between information clarity and visual interference

AI summary
An information processing device includes a control unit that displays, when another vehicle that is running in front of an own vehicle in a traveling direction is detected by a detection unit, a graphic image in which information related to inter-vehicle time required for the own vehicle to reach a position at which the other vehicle exists is schematized on a display unit in the own vehicle, and another vehicle image in which the other vehicle is shown in a position at which an inter-vehicle distance between the own vehicle and the other vehicle is reflected on a front side of the graphic image in the traveling direction without being overlapped with the graphic image.
