Synchronized Driver-Vehicle Data Recording for Cause Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability to effectively analyze the cause of abnormal driver behavior, such as falling asleep, by not synchronizing and reproducing relevant vehicle and driver behavior data for comprehensive analysis.
Innovation Solution
An information recording and reproduction system that synchronizes and accumulates driver and vehicle behavior data from onboard devices, allowing for synchronized reproduction and analysis of abnormal behaviors, enhancing data usefulness for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driver behavior data and vehicle behavior data are recorded separately without synchronization, then data storage is simpler, but the ability to analyze the cause of abnormal driver behavior is insufficient
Solution Approach 1:
The patent merges driver behavior data and vehicle behavior data into a unified synchronized data structure by integrating multiple data sources (camera images, sensor data, vehicle state information) with unique identification and timing information, enabling comprehensive cause analysis while maintaining manageable system complexity through standardized data integration protocols
2Loss of information
If multiple types of behavior data are accumulated without synchronized reproduction, then data accumulation is faster, but data usefulness for analysis is reduced
Solution Approach 1:
The patent applies preliminary action by embedding synchronization timestamps and unique identification information in each data record at the moment of data generation, rather than performing synchronization during data processing. This pre-synchronization approach preserves data correlation for analysis while maintaining efficient data processing and storage operations
Data Source
AI summary
An information recording and reproduction device includes a processor including hardware and configured to: acquire first information indicating information relating to a behavior of a driver from a first device mounted in a vehicle; acquire second information indicating information relating to a behavior of the vehicle from a second device mounted in the vehicle; and accumulate the first information and the second information in a memory in a synchronously reproducible manner.
