Drive Recorder Driver Habit Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive recorders are unable to accurately determine driving habits of individual drivers as they do not account for variations in driving characteristics such as braking and acceleration styles.
Innovation Solution
A situation information management system that includes a drive recorder and a server, which sets customized transmission determination ranges based on driver characteristics by analyzing acceleration data, allowing for the identification of unique driving habits and adjusting transmission criteria accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed transmission determination ranges are used for all drivers, then the system is simple to operate, but it cannot accurately determine individual driving habits
Solution Approach 1:
The system performs preliminary learning of driver characteristics by collecting and analyzing acceleration patterns during an initial period. This preliminary action establishes a baseline of each driver's normal driving behavior before actual transmission determination begins, enabling accurate individualized assessment without requiring complex real-time analysis
Solution Approach 2:
The system implements feedback by comparing actual acceleration data against learned driver characteristics and automatically adjusting transmission determination ranges. The server receives acceleration information, analyzes deviations from normal patterns, and dynamically modifies transmission thresholds to match individual driving styles, improving accuracy while maintaining operational simplicity
2Measurement precision
If transmission determination ranges are customized for each driver, then driving habit determination accuracy improves, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that handles all complex customization operations. It receives acceleration data from the drive recorder, performs sophisticated analysis of driver characteristics, calculates personalized transmission determination ranges, and sends control parameters back to the recorder. This intermediary approach enables accurate customization while keeping the in-vehicle device simple
Solution Approach 2:
The system segments the transmission determination process into distinct phases: a learning phase where driver characteristics are collected and analyzed, and an operational phase where customized ranges are applied. This segmentation allows the system to establish accurate individualized parameters without requiring complex simultaneous processing, reducing overall system complexity

AI summary
A drive recorder is disposed in a vehicle, and includes a situation information transmitter, a character information transmitter, and an updater. The situation information transmitter transmits situation information to a server upon determining that an acceleration of the vehicle is within a transmission determination range that is stored in a storage device, which is indicative that the acceleration of the vehicle is within the transmission detection range. The character information transmitter transmits character information indicative of a character of a driver of the vehicle regarding a drive operation which at least includes the acceleration of the vehicle. The updater (i) receives, from the server, a character reflection range regarding a range of the acceleration of the vehicle being set based on the character information and (ii) updates the transmission determination range stored in the storage device based on the received character reflection range.
