Automatic Driving Status Alerts for Notification Failure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic travelling control systems fail to correctly notify users of abnormalities in the notification of the status of automatic travelling functions, leading to user concern about potential functional abnormalities.
Innovation Solution
An automatic travelling control system that includes a function determiner, first and second notifiers, a manual driving capability determiner, and a manual driving requester to detect and notify abnormalities in the notification of the status of automatic travelling functions, and request manual driving when necessary, using various equipment types for notification based on priority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system notifies abnormalities in the notification of automatic travelling functions, then user awareness of actual system status is improved, but user anxiety and confusion increase due to unclear distinction between notification abnormalities and functional abnormalities
Solution Approach 1:
The notification system is segmented into distinct types: first notifications for functional status and second notifications for notification abnormalities. Each type uses different display characteristics (e.g., different colors, positions, or patterns) to clearly distinguish between functional issues and notification issues, preventing user confusion while maintaining complete information transparency.
Solution Approach 2:
A distinction indicator or intermediary visual element is introduced to mediate between the abnormality notification and the user. This intermediary clearly marks that the abnormality pertains to the notification system itself rather than the automatic travelling function, reducing user anxiety by providing clear contextual information.
2Loss of information
If the system provides detailed notification about abnormalities, then information completeness is improved, but notification complexity and user cognitive load increase
Solution Approach 1:
The notification system segments information into hierarchical levels: essential information (what is abnormal), cause information (why it is abnormal), and detailed information (technical specifics). Users can access complete information when needed while receiving simplified summaries during normal operation, balancing completeness with cognitive load.
Solution Approach 2:
Different parts of the notification interface provide different levels of detail. The main display area shows essential information with simple characteristics, while detailed information is available in expandable sections or separate displays. This local differentiation of information quality reduces overall notification complexity while maintaining completeness.

AI summary
An automatic travelling control system includes: a function determiner that determines a status of a function used for automatic travelling of a vehicle; a first notifier that provides a notification of the status of the function; a first abnormality detector that detects an abnormality in the notification of the status of the function; a second notifier that provides a predetermined notification when the abnormality in the notification of the status of the function is detected and it is determined that the function is normal; a second abnormality detector that detects an abnormality in the predetermined notification; a manual driving capability determiner that determines whether a user on board the vehicle can drive the vehicle manually; and a manual driving requester that requests the user to drive the vehicle manually when the second notifier provides the predetermined notification and it is determined that the user can drive the vehicle manually.
