Route Guidance Image Positioning for Overlapping Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving route guidance systems, such as HUD apparatuses, struggle to accurately guide drivers when multiple routes are close together, as the displayed route guidance images overlap with the front scenery, making it difficult for drivers to distinguish the intended route.
Innovation Solution
A moving route guidance device that includes display control means to adjust the content and position of the route guidance image based on the vehicle's position information, using route identification images corresponding to the visually recognized positions of multiple routes and associating them with route instructing images to clearly indicate the guided route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the route guidance image is displayed to overlap the front scenery in the moving body advancing direction, then the driver can visually recognize the route guidance image through the windshield, but it becomes difficult for the driver to accurately recognize which of multiple close movable routes is the guided route
Solution Approach 1:
The route guidance image is segmented into multiple route identification images, each corresponding to a different movable route. When multiple routes are close to each other, the system divides the guidance information into separate visual elements (first route identification image and second route identification image) that are displayed at different positions on the windshield, allowing the driver to distinguish between closely spaced routes while maintaining overlap with the front scenery.
2Device complexity
If a single route guidance image is displayed for multiple close routes, then the display apparatus remains simple, but the driver cannot distinguish which specific route is being guided
Solution Approach 1:
When multiple routes are close to each other in the horizontal direction, the system displays route identification images at different vertical positions on the windshield. This dimensional transformation allows the driver to distinguish between routes that are close horizontally by using vertical separation in the display, thereby improving route position discrimination without adding complex hardware.
3Device complexity
If the route guidance image is displayed at a fixed position, then the display control is simple, but the guidance accuracy decreases when the vehicle position changes
Solution Approach 1:
The display control unit dynamically adjusts the position and content of route identification images based on the vehicle's current position and the spatial relationship between multiple routes. As the vehicle moves closer to an intersection or when routes are at different distances, the system modifies which route identification images are displayed and at what positions, ensuring accurate guidance while maintaining relatively simple display control logic.

AI summary
The moving route guidance device includes: display control means configured to execute display control to change at least one of a content and a display position of the route guidance image based on position information of the moving body. The route guidance image includes: a plurality of route identification images respectively corresponding to the plurality of the movable routes that are close to each other and displayed in a manner to correspond to a visually recognized position relationship between the plurality of the movable routes by the driver or a predetermined reference position; and an route instructing image displayed in association with the route identification image that corresponds to the moving route guided by the route guidance image of the plurality of the movable routes.
