Solution Overview

Problem

Current drive recorders are not adequately developed to handle vehicles with switching functions between manual and autonomous driving modes, lacking the necessary technology for recording and displaying driving information effectively across different modes.

Innovation Solution

A driving information recording apparatus and method that records driving conditions, including image information, in association with the driving mode at the time of the condition, and a display processing system that displays this information on a map with route history, allowing for specific location playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large number of pieces of driving information are accumulated in the storage unit, then the information can be used for various analyses and retrials, but the storage unit may become full and prevent new information from being stored

Engineering Contradiction:
Improvequantity of driving informationVSAvoidstorage capacity availability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system automatically discards driving information that has been determined to have low importance (through evaluation criteria) when the storage unit is full, while preserving high-importance information. This allows continuous operation and storage of valuable data without being constrained by fixed storage capacity, effectively recovering storage space for new information while maintaining data quality.

Inventive Principle:
Principle #34Discarding and recovering

2Quantity of substance

If all driving information is displayed on the display unit, then the driver can access complete information, but important information may be lost among a large number of pieces of information

Engineering Contradiction:
Improvequantity of displayed informationVSAvoidinformation identification accuracy
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The display unit presents driving information with differentiated visual characteristics based on importance level. High-importance information is displayed with distinctive visual properties (such as highlighting, larger font, or different color) to make it easily identifiable, while lower-importance information is displayed with standard characteristics. This allows the driver to quickly identify critical information without being overwhelmed by the total volume of data.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the storage unit stores a large amount of driving information, then various analyses and retrials can be performed, but the system complexity increases

Engineering Contradiction:
Improveanalysis capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The evaluation unit performs preliminary assessment of driving information importance at the time of storage, assigning importance levels before data is saved. This pre-categorization allows the storage system to efficiently manage data without requiring complex real-time analysis during retrieval, simplifying the overall system architecture while maintaining versatile analysis capabilities across different scenarios.

Inventive Principle:
Principle #10Preliminary action
