Vehicle Display Control for Low-Speed Icon Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
At low vehicle speeds, the distance between vehicles shortens, causing the following vehicle's icon to overlap with the host vehicle's icon on a display device, impairing the driver's visual recognition ability.
Innovation Solution
A vehicle display system that includes a vehicle detection device, a speed detection device, and a display control unit, which blanks out or displays transparently the following vehicle's icon when the host vehicle's speed is low, preventing overlap and maintaining visual recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device shows all detected vehicles including following vehicles, then the information completeness about surroundings is improved, but the visual recognition ability of the host vehicle deteriorates due to icon overlap at low speeds
Solution Approach 1:
The display control unit applies different display properties to different regions of the display device. Specifically, when a following vehicle is detected at low host vehicle speed, the control unit makes the following vehicle icon transparent or blanks it out only in the region where it would overlap with the host vehicle icon, while maintaining normal display of other vehicles and regions. This local differentiation resolves the contradiction by preserving information completeness overall while eliminating visual recognition interference in the critical overlap region.
2Adaptability or versatility
If the display device displays the following vehicle icon, then the monitoring of rear vehicles is improved, but the icon overlaps with the host vehicle icon at low speeds causing visual confusion
Solution Approach 1:
The display control unit dynamically adjusts the display state of the following vehicle icon based on real-time conditions, specifically host vehicle speed and the presence of a following vehicle. When the host vehicle speed is below a predetermined threshold and a following vehicle is detected, the control unit switches the following vehicle icon to a transparent or blanked-out state. This dynamic adaptation allows the system to maintain monitoring capability while ensuring visual clarity under specific operating conditions.
3Use of energy by moving object
If the host vehicle speed is low, then the fuel consumption is reduced, but the distance to following vehicles shortens causing icon overlap on display
Solution Approach 1:
The display control unit implements a preliminary anti-action by proactively blanking out or transparentizing the following vehicle icon when it is detected that the host vehicle is moving at low speed and a following vehicle is present. This preventive measure counteracts the potential harmful effect of icon overlap before it degrades visual recognition, allowing the host vehicle to maintain low-speed operation without compromising display clarity.

AI summary
A vehicle display system includes a vehicle detection device detecting at least one other vehicle present in surroundings of a host vehicle, a vehicle speed detection device detecting a speed of the host vehicle, a display device displaying the host vehicle and the at least one other vehicle respectively as vehicle icons, and a display control part configured to control a content of display of the display device. When the speed of the host vehicle is equal to or less than a predetermined value, the display control part is configured to blank out the display of or display transparently at least a part of a vehicle icon of a following vehicle detected by the vehicle detection device and positioned at a rear of the host vehicle in a driving lane of the host vehicle.
