Vehicle Object Display Control With Adaptive Distance Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems uniformly display objects around a vehicle without considering specific conditions, leading to unnecessary early display of objects that do not require immediate attention.
Innovation Solution
A display control apparatus that adjusts the distance threshold for displaying objects based on vehicle position and time conditions, allowing early display of critical objects only when these conditions are met, and adjusts thresholds based on object type and presence of obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the distance threshold is uniformly increased for all objects, then early display of objects is achieved, but unnecessary early display of non-critical objects occurs
Solution Approach 1:
The patent applies local quality by setting different distance thresholds for different objects based on their attributes. Critical objects (e.g., children, pedestrians) receive a larger distance threshold for early display, while non-critical objects maintain the standard threshold. This resolves the contradiction by making the threshold increase localized to specific object types rather than uniform across all objects.
Solution Approach 2:
The patent changes the distance threshold parameter dynamically based on object attributes and vehicle conditions. The display control apparatus adjusts the threshold value selectively for different object types, enabling early display of critical objects without triggering unnecessary early displays of non-critical objects. This parameter change approach resolves the contradiction between early display and display accuracy.
2Loss of time
If the distance threshold is increased for early display, then critical objects are displayed earlier, but display information increases for all objects
Solution Approach 1:
The patent applies local quality by selectively increasing the distance threshold only for critical object types (such as children and pedestrians) while maintaining the standard threshold for other objects. This ensures that display information volume increases only for relevant critical objects rather than all objects, resolving the contradiction between early detection and information volume.
3Ease of operation
If uniform early display is applied to all objects, then detection simplicity is maintained, but attention focus is diluted
Solution Approach 1:
The patent applies local quality by implementing different display control strategies for different object types. Critical objects receive enhanced early display with larger distance thresholds, while non-critical objects use standard thresholds. This maintains operational simplicity through automated attribute-based classification while preserving attention focus on critical objects, resolving the contradiction between simplicity and attention priority.

AI summary
A display control apparatus includes: an object recognition unit configured to recognize an object around a vehicle based on a detection result of an external sensor mounted on the vehicle; a display target specification unit configured to specify the object present within a predetermined distance threshold around the vehicle as a display target object; and a display control unit configured to display the display target object on a display unit. The display target specification unit sets the distance threshold when a predetermined vehicle position condition or a predetermined time condition related to a predetermined object for early display is satisfied to be greater than the distance threshold when the vehicle position condition and the time condition are not satisfied.
