Vehicle Display Controller Branch Merge Lane Alert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing driving support systems, important information for drivers is often overlooked when various types of information are displayed as images, making it difficult for drivers to easily recognize critical guidance for lane changes and route navigation.
Innovation Solution
A display device and method that distinguishes between branch and merge lanes by displaying specific images indicating the presence of branch or merge points ahead, using distinct arrow directions and colors to alert the driver, ensuring they recognize important lane change information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If various types of information for driving support are displayed as an image, then the driver receives comprehensive route and road information, but the driver may overlook important information in the image
Solution Approach 1:
The display device segments information by displaying only the most critical element (branch/merge point ahead) when the vehicle is in a branch or merge lane, rather than showing all route and road information simultaneously. This segmentation allows the driver to immediately recognize the most important safety-critical information without being overwhelmed by other details.
Solution Approach 2:
The system applies local quality by changing the display mode specifically for the second image (branch/merge point indication) when the vehicle is in a branch or merge lane, while maintaining the first image display for other situations. This localized change in display quality ensures that critical information receives enhanced visual attention exactly where needed.
2Loss of information
If the display shows detailed route information including multiple elements, then the driver receives comprehensive navigation guidance, but the driver may overlook critical lane change information
Solution Approach 1:
The system extracts the most critical information element (branch/merge point ahead) from the complete set of route and road information and displays it separately as a second image with enhanced visibility. This extraction ensures that the most safety-critical information is prominently displayed and cannot be overlooked, while the first image can still show other route information if needed.
Solution Approach 2:
The display device uses color changes or visual emphasis to differentiate the second image (branch/merge point indication) from the first image (route information). This visual differentiation through color or display mode changes ensures that critical lane change information stands out and captures the driver's attention reliably.
3Adaptability or versatility
If the display device shows all route and road information simultaneously, then the driver has access to complete navigation data, but the driver cannot easily recognize important information for driving support
Solution Approach 1:
The display device dynamically changes the display mode based on the vehicle's lane status. When the vehicle is in a branch or merge lane, the system automatically switches to displaying the second image with enhanced visibility. This dynamic adaptation ensures that the most relevant information is always prominently displayed according to the current driving context, making information recognition easier without sacrificing completeness.

AI summary
A display device includes a display that displays an image, a display controller that causes the display to display a first image indicating at least one of route information and road information on a route to a destination of a vehicle, and a determiner that determines that a traveling lane in which the vehicle is present among one or a plurality of lanes included in the route is a branch lane which branches from the route or a merge lane which merges into another lane, wherein the display controller causes the display to display a second image indicating that a branch point or a merge point is present ahead in a travel direction of the vehicle without displaying the first image when the determiner has determined that the traveling lane is the branch or merge lane.
