Vehicle Notification System Confidence-Based Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information providing systems lack the ability to dynamically adjust notifications based on the confidence level of detected impediment events, potentially leading to misleading or incomplete information for drivers, and do not continuously collect data on zones where autonomous driving is challenging, resulting in uniform and inadequate notifications.
Innovation Solution
An information providing apparatus for vehicles that includes a traffic information database and a data processing device capable of detecting impediment events, extracting relevant information, and generating notifications based on the confidence level of analysis results, ensuring that only reliable and detailed information is provided to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notification contents are made detailed and specific, then driver preparedness and handling capability improve, but reliability decreases when confidence level is low
Solution Approach 1:
The notification system dynamically adjusts its information content based on the confidence level of the impediment event detection. When confidence is high, detailed information is provided; when confidence is low, notifications are withheld or generalized. This dynamic adaptation resolves the contradiction by making the system flexible rather than static in its information provision strategy.
Solution Approach 2:
The system changes the parameter of notification detail level based on the confidence level parameter. By establishing a relationship between confidence level (threshold) and information content (output parameter), the system optimizes both information completeness and reliability simultaneously through parameter-based control.
2Device complexity
If uniform notifications are provided for all impediment events, then system complexity is reduced, but driver assistance effectiveness deteriorates
Solution Approach 1:
Instead of applying a uniform notification approach to all impediment events, the system applies different notification strategies based on local conditions - specifically the confidence level of each detected event and the specific type of impediment. This local quality approach tailors notifications to individual event characteristics, improving driver assistance effectiveness without requiring overly complex system architecture.
3Measurement precision
If data collection continues to accumulate more information on impediment events, then measurement precision improves, but loss of time for processing increases
Solution Approach 1:
The system performs preliminary data collection and analysis during normal operation, building confidence levels and event profiles before notifications are needed. By continuously accumulating data in the background and pre-processing information, the system reduces the time required for real-time decision-making while maintaining high measurement precision through accumulated knowledge.
Data Source
AI summary
An information providing apparatus includes a traffic information database and a data processing device. The data processing device detects, based on the traffic information data, an impediment event. The data processing device extracts the impediment event potentially encountered by an assisted vehicle. The data processing device provides a driver of the assisted vehicle with a notification regarding the impediment event potentially encountered by the assisted vehicle. The data processing device generates, based on the traffic information data, item data regarding a detailed item defined with respect to the impediment event. The data processing device generates, based on the item data, an analysis result regarding the detailed item and a confidence level of the analysis result. The data processing device changes, depending on the confidence level, contents regarding the analysis result to be included in the notification.
