Lead Vehicle HUD Display Switching Outside Mark Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies in head-up displays fail to provide clear indication when a following mark for a lead vehicle cannot be displayed within the set display region, leading to user insecurity due to uncertainty about lead vehicle detection.
Innovation Solution
Implement a display control system that performs first display when the following mark is within the set display region and second display when it falls outside, using techniques such as overlapping, adjacent positioning, or emphasizing elements like the meter display section's edge to indicate lead vehicle detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the following mark is displayed only within the set display region, then the display clarity is improved, but the user awareness of lead vehicle detection is lost when the mark falls outside the region
Solution Approach 1:
The display information is segmented into two distinct modes: first display for normal following mark presentation within the set display region, and second display for indicating lead vehicle detection when the mark falls outside the region. This segmentation allows each display mode to optimize for its specific purpose while maintaining overall system functionality.
Solution Approach 2:
The display control section dynamically switches between first display and second display based on the real-time position of the following mark relative to the set display region. This dynamic adaptation ensures that the display always provides appropriate information regardless of the lead vehicle's position.
2Device complexity
If the following mark is displayed at a position separated by a gap from the lead vehicle, then the display complexity is reduced, but the user's intuitive awareness of the mark's correspondence to the lead vehicle is diminished
Solution Approach 1:
The display system applies different display qualities and positions based on the specific situation. When the following mark can be displayed within the set display region, it is positioned to overlap or be adjacent to the lead vehicle for maximum intuitiveness. When outside the region, the second display mode is activated to maintain user awareness.
3Area of stationary object
If the following mark is displayed in the meter display region, then the display area is maximized, but the visibility of the meter display section is obstructed
Solution Approach 1:
The display area is segmented into a set display region and a meter display region. The following mark is restricted to the set display region, which excludes the meter display region where the meter display section is located. This segmentation prevents obstruction of the meter display section while still utilizing the available display area effectively.

AI summary
A display control device includes a display control section that is configured to: perform first display in cases in which a display position of a following mark corresponding to a lead vehicle detected by a lead vehicle detection section for detecting lead vehicles is within a set display region set in advance in a display area of a display device by displaying the following mark at the display position; and perform second display to indicate that the lead vehicle is being detected in cases in which the display position falls outside the set display region.
