Vehicle Occupant Social Credibility Evaluation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional evaluation systems cannot determine a driver's social reliability, as they only assess compliance with traffic rules and not sociability or manners, such as consideration for other drivers.
Innovation Solution
An evaluation system that acquires images and information about a vehicle occupant's behavior using in-vehicle cameras and sensors, assigns a social credibility score based on desirable or undesirable actions, and estimates accident occurrence to evaluate the occupant's social credibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional evaluation systems only assess compliance with traffic rules, then the evaluation process is simple and straightforward, but the evaluation cannot determine social reliability or sociability of the driver
Solution Approach 1:
The evaluation system segments the assessment into multiple dimensions: traffic rule compliance (traditional) and social reliability (new). The evaluation unit separately processes different types of behaviors - rule-based violations versus socially undesirable behaviors - and combines them into a comprehensive evaluation score, allowing precise measurement without overwhelming system complexity
Solution Approach 2:
The evaluation unit is designed to perform multiple functions: it evaluates both traffic rule compliance and social reliability using the same basic architecture. The system universally applies evaluation criteria across different behavior types, making the system versatile while maintaining manageable complexity through standardized processing
2Reliability
If the evaluation system uses multiple data sources including images, sensing results, and accident history, then the evaluation comprehensiveness is improved, but the system complexity increases
Solution Approach 1:
The evaluation unit merges multiple data sources - exterior images from acquisition units, sensing results from vehicle sensors, and accident history information - into a unified evaluation process. By combining these diverse inputs through a single evaluation unit that applies consistent criteria, the system achieves high reliability while controlling complexity through integrated processing
Solution Approach 2:
The evaluation unit acts as an intermediary that processes and synthesizes information from multiple sources. It mediates between the raw data from acquisition units/sensors and the final evaluation score, transforming diverse inputs into a unified assessment without requiring complex direct connections between all data sources
3Measurement precision
If the evaluation unit detects and classifies behaviors in patterns, then the evaluation accuracy is improved, but the processing time and complexity increase
Solution Approach 1:
The evaluation unit employs pre-defined behavior patterns and classification criteria that are established in advance. By having predetermined categories for desirable and undesirable behaviors, the system can quickly match observed behaviors to known patterns without requiring complex real-time analysis, thus improving accuracy while minimizing processing time

AI summary
An evaluation system includes: an acquisition unit that acquires an image acquired by imaging an exterior of a vehicle; and an evaluation unit that derives and assigns an evaluation point for evaluating social credibility of a vehicle occupant of the vehicle on the basis of the image acquired by the acquisition unit.
