Vehicle Display Control for Selective Intersection Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems do not adequately consider conditions for displaying guide marks, leading to potential confusion for vehicle occupants.
Innovation Solution
A display control system that acquires intersection information from a planned travel route and selectively displays animations or static images in front of the vehicle occupant, based on predetermined conditions such as intersection type, visibility, and reliability of position information, to prevent confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If guide marks are displayed in a superimposed manner on the road surface, then the vehicle occupant can intuitively grasp the position of the intersection, but the vehicle occupant may become confused due to the displaying of guide marks
Solution Approach 1:
The system changes the display parameters (animation type, superimposition position, visibility) based on the intersection category and vehicle state to optimize information presentation while avoiding confusion
Solution Approach 2:
Different display strategies are applied to different intersection categories (e.g., ordinary intersections vs. complex intersections), providing localized optimization for each scenario
2Loss of information
If animations are displayed for all intersections, then the vehicle occupant can grasp the position of intersections, but the processing load increases and clarity may be reduced
Solution Approach 1:
The system extracts and identifies specific intersection categories from the planned travel route, then selectively applies display animations only to appropriate intersection types, removing unnecessary display operations
Solution Approach 2:
The display control is segmented into different strategies based on intersection category, with ordinary intersections receiving animation display and complex intersections receiving different treatment

AI summary
A display control device for a vehicle, includes: an intersection information acquiring section that acquires, from a planned travel route of a vehicle that is set in advance, information of an intersection through which passage is planned; and an image display section that, if the intersection is not an intersection satisfying a predetermined condition, in a case in which the vehicle approaches the intersection, causes display of an animation that heads toward the intersection in a display region provided in front of a vehicle occupant and in a manner of being superimposed on a foreground, and, if the intersection is an intersection satisfying the predetermined condition, does not cause display of the animation.
