In-Vehicle Stop Cause Display for Intersection Passage Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display systems fail to notify occupants of the reason for a stoppage when the vehicle stops due to causes other than traffic regulations, leading to anxious feelings among occupants.
Innovation Solution
The system acquires an intersection area where another moving object can move, recognizes the travel environment, determines if the vehicle can pass through the intersection, and notifies occupants using a display device to emphasize the cause of the stoppage by adjusting the display contrast.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops due to causes other than traffic regulations (e.g., obstacles), then the vehicle can avoid collisions and ensure safety, but the occupants feel anxious because they are not informed of the reason for stoppage
Solution Approach 1:
The system provides feedback to occupants by displaying the cause of stoppage on a display device. The notification unit notifies occupants of the reason for stoppage (e.g., obstacle detection results) when the vehicle stops due to causes other than traffic regulations, thereby reducing anxiety through information feedback.
2Loss of information
If the system notifies occupants of all stoppage causes, then occupant awareness is improved, but the complexity of the notification system increases
Solution Approach 1:
The system applies local quality by providing differentiated notification based on stoppage cause. It selectively notifies occupants only when the stoppage is due to causes other than traffic regulations (e.g., obstacles), while not notifying for routine traffic-related stops. The display also differentiates between intersection areas and other areas, providing targeted information rather than universal notifications.
3Loss of information
If the display emphasizes the cause of stoppage, then occupant understanding is improved, but the display contrast and visual hierarchy become more complex
Solution Approach 1:
The display device applies local quality by differentiating display characteristics between intersection areas and other areas. When the vehicle stops in an intersection area, the display shows the cause with different contrast or emphasis compared to stops in other areas, helping occupants quickly understand the reason for stoppage while maintaining a relatively simple display structure.

AI summary
An information providing device includes an acquisition unit configured to acquire an intersection area on a travel route, the intersection area intersecting with an area in which another moving object can move; a recognition unit configured to recognize a travel environment around a vehicle; a determination unit configured to determine, based on the travel environment, whether or not the vehicle can pass through the intersection area; and a notification unit configured to notify an onboard terminal and/or an electronic terminal in the vehicle of a cause of the vehicle being unable to pass through the intersection area when the determination unit determines that the vehicle cannot pass through the intersection area. When notifying the cause using a display device, the notification unit lowers a contrast of a display portion of the intersection area relative to a display portion of the travel route and increases a degree of emphasizing a display portion of the cause.
