Autonomous Driving Route Display for Safety Check Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing on-vehicle display devices struggle to intuitively convey the range for which safety checks have been completed during autonomous driving.
Innovation Solution
A display control device and method that acquire a travel route and surrounding information, performing safety checks, and display a travel route image distinguishing completed and incomplete safety check ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a stop indication is displayed extending upward from the road surface, then the stopped state of the vehicle can be indicated, but it is difficult for viewers to intuitively grasp the range for which safety check has been completed
Solution Approach 1:
The travel route is segmented into multiple ranges: a first range where safety check is completed (displayed in green) and a second range where safety check is not yet completed (displayed in yellow). This segmentation allows viewers to intuitively grasp which portions of the route have been verified for safety, directly resolving the problem of unclear safety check completion range information.
Solution Approach 2:
Different colors are used to represent different safety check statuses: green indicates completed safety check areas while yellow indicates areas pending safety check. This color-coding system enhances the intuitive understanding of the safety check completion range, making the information immediately comprehensible to viewers.
2Loss of information
If the travel route is displayed with detailed safety check information, then the safety check completion range can be clearly shown, but the display complexity increases
Solution Approach 1:
The route is divided into discrete segments (first range and second range) with clear boundaries. This segmentation simplifies the display processing by allowing the system to handle each segment independently, reducing overall complexity while still providing comprehensive safety check information.
Solution Approach 2:
Different visual qualities (colors) are applied to different portions of the route based on their safety check status. This local differentiation allows the display to convey detailed safety information without requiring complex overall processing, as each segment is handled with its own specific visual characteristics.

AI summary
A display control device includes a controller (30). The controller (30) acquires a travel route of a subject vehicle having an autonomous traveling function, acquires information on a state of surroundings of the subject vehicle, performs, based on the state of surroundings of the subject vehicle, safety check required for the subject vehicle to travel on the travel route by autonomous traveling, and causes a display device (31) to display a travel route image including a first range being completed in safety check and a second range other than the first range that are distinguished on the travel route.
