Solution Overview

Problem

Existing technologies face challenges in accurately identifying and specifying the user who is driving a vehicle, which is crucial for determining car insurance rates based on driving skill and safety.

Innovation Solution

The system employs a learning model that estimates the group of users on board a vehicle by comparing terminal positions with vehicle positions, and generates a model using identification information, driving attributes, and vehicle attributes as training data to specify the driver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If terminal position data and vehicle position data are collected and compared to identify on-board users, then user identification accuracy is improved, but system complexity and data processing burden increase

Engineering Contradiction:
Improveuser identification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the user identification process into distinct functional modules: a terminal position data acquisition unit that collects terminal location information, a vehicle position data acquisition unit that collects vehicle location information, and an on-board user identification unit that compares these datasets to determine which terminals are on-board users. This segmentation allows each module to perform a specific function, improving identification accuracy while managing system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If comprehensive training data including user identification information, driving attributes, and vehicle attributes is collected to generate learning models, then driver specification accuracy is improved, but data processing time and computational resources increase

Engineering Contradiction:
Improvedriver specification accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary data collection and organization by gathering terminal position data, vehicle position data, user identification information, driving attributes, and vehicle attributes in advance. This pre-collected comprehensive dataset is then used to generate learning models, which reduces the computational burden and processing time required during actual driver specification operations, as the model generation can be performed offline or in advance.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple data sources including terminal data and vehicle data are integrated for on-board user estimation, then identification reliability is improved, but information processing load increases

Engineering Contradiction:
Improveidentification reliabilityVSAvoidinformation processing load
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system introduces an on-board user identification unit as an intermediary component that receives and processes both terminal position data and vehicle position data. This intermediary unit compares the datasets and generates identification results, thereby integrating multiple data sources to improve reliability while managing the information processing load through a dedicated specialized component rather than distributed processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Learning model generating unit 332 generates a learning model using a user ID of a user estimated by driver estimating unit 331 and driving attributes of the user, as training data. Specifically, learning model generating unit 332 generates a learning model in which the driving attributes are an explanatory variable and the user ID of a user is an objective variable. When various driving attributes are input to this driving behavior model, the user ID of a driver specified by the attributes is output.
