Vehicle Notification Filtering for Driver Annoyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information providing systems frequently notify drivers of impediment events that are already visually confirmed or expected, leading to driver annoyance, as they provide notifications for all zones difficult for autonomous traveling, including familiar commuting routes.
Innovation Solution
An information providing apparatus for vehicles that selectively notifies drivers of impediment events with high notification necessity, using a data processing device to detect, extract, and calculate notification levels based on traffic information, driver history, and event characteristics, filtering out expected and repetitive notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system notifies the driver of all impediment events on the travel route, then the driver can recognize all potential hazards, but the driver becomes annoyed by receiving notifications of useless information such as familiar sites
Solution Approach 1:
The system extracts only the necessary subset of impediment events from the complete set of all events on the travel route. By calculating notification necessity levels and comparing them against thresholds, the system selectively notifies only those events that meet the criteria, filtering out familiar or low-priority events that would cause driver annoyance while maintaining comprehensive hazard awareness.
2Reliability
If the system provides notifications for all zones difficult for autonomous traveling, then the driver can prepare for all such zones, but the notification becomes less useful for general vehicles on familiar commuting routes
Solution Approach 1:
The system applies different notification strategies to different impediment events based on their local characteristics. By calculating notification necessity levels that consider event type, location, and driver behavior patterns, the system tailors notifications to each specific event's importance and the driver's familiarity with that area, making the notification system adaptable to both autonomous traveling zones and general commuting routes.
3Reliability
If the system notifies the driver of expected events such as junctions and grade separations on familiar routes, then the driver can maintain awareness, but the driver finds such notifications annoying
Solution Approach 1:
The system performs preliminary analysis of impediment events to determine their notification necessity before issuing notifications. By calculating notification necessity levels in advance and comparing them against thresholds, the system proactively identifies which events warrant notification and which should be filtered out, preventing annoying notifications before they reach the driver while maintaining necessary awareness.

AI summary
An information providing apparatus for a vehicle includes: a traffic information database in which traffic information data are recorded; and a data processing device that processes the traffic information data to provide a driver of an assisted vehicle with a notification. The data processing device executes: an event detection process that detects, based on the traffic information data, an impediment event that impediments vehicle running; an event extraction process that extracts the impediment event potentially encountered by the assisted vehicle; a determination value calculation process that calculates a notification necessity level for each impediment event; and a notification process that provides the driver of the assisted vehicle with the notification regarding the impediment event potentially encountered by the assisted vehicle and having the notification necessity level greater than a threshold.
