Solution Approach 1:

The patent combines multiple data sources (acceleration data from sensors and sound evaluation data from operators) into a unified evaluation system. The map generation process integrates both automated driving data and human operator assessments, merging objective sensor measurements with subjective human evaluations to achieve comprehensive evaluation while maintaining manageable processing complexity through structured data integration.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple data sources are integrated for comprehensive evaluation, then the evaluation reliability improves, but the data processing complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent segments the evaluation process into distinct components: automated driving data extraction from sensors, sound evaluation data collection from operators, and integrated analysis. By dividing the comprehensive evaluation into modular segments that can be processed independently and then combined, the system achieves thorough evaluation coverage while keeping processing complexity manageable through structured segmentation of data sources and analysis steps.

Inventive Principle:

Solution Approach 1:

The patent implements a self-service approach where operators naturally provide sound evaluation data through their normal driving interactions and feedback mechanisms. The system captures operator evaluations during regular operation without requiring separate dedicated data collection sessions or complex intervention protocols. This allows accurate problem identification through genuine operator insights while minimizing the complexity of data collection infrastructure.

Inventive Principle:
Principle #25Self-service

AI summary

A processing method, which is executed by a processor to execute a process associated with automated driving of a moving body, includes: extracting, from dynamic data embedded in association with traveling points of the moving body on a digital map, automated driving data representing an automated driving state of the moving body at an analysis traveling point and sound evaluation data representing evaluation by a sound from an operator regarding the automated driving state at the analysis traveling point; and generating, based on the automated driving data, factor analysis data correlated with the sound evaluation data as a result of analyzing a factor of the automated driving state at the analysis traveling point. The generating of the factor analysis data includes: selecting the automated driving data correlated with the sound evaluation data; and generating the factor analysis data based on the selected automated driving data.
