Driver Performance History Recording and Scoring Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle event recording systems lack automated means to associate captured data with the vehicle operator, requiring manual intervention for data manipulation and reporting, and are inaccessible to parties without specific software, limiting remote reporting and analysis capabilities.
Innovation Solution
A system that automatically collects and processes data to form a driver performance history report by associating vehicle event records with the operator, using an associator to connect event records with operator identification information, and applying algorithms to produce a single value performance score, enabling long-term storage and remote analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual intervention is used to manipulate and report vehicle event data, then data accuracy can be maintained, but labor time and operational complexity increase
Solution Approach 1:
The system automatically associates event data with operator information without requiring manual intervention. The associator component autonomously links event records to operator identification data, eliminating the need for manual data manipulation while maintaining data accuracy through automated processes.
Solution Approach 2:
The patent introduces an associator as an intermediary component that bridges event data and operator information. This mediator automatically performs the association function, reducing system complexity by encapsulating the automation logic in a dedicated component rather than requiring complex manual procedures.
2Ease of operation
If specialized software is required to access vehicle event data, then data security is improved, but accessibility and ease of operation deteriorate
Solution Approach 1:
The system generates standardized reports that can be accessed and processed by multiple parties without requiring specialized software. The report format is designed to be universally readable, allowing insurance companies, employers, and other stakeholders to access performance data through standard interfaces while maintaining security through controlled data generation and distribution.
3Measurement precision
If comprehensive vehicle event data is collected and stored, then performance analysis accuracy improves, but data storage requirements and processing time increase
Solution Approach 1:
The system extracts only the essential performance metrics and event data needed for accurate performance measurement, rather than storing and processing all possible vehicle data. The associator selectively associates relevant event data with operator information, reducing data volume while maintaining measurement precision by focusing on critical performance indicators.
4Loss of time
If real-time performance monitoring is implemented, then operational feedback is improved, but energy consumption and system complexity increase
Solution Approach 1:
The system implements periodic performance monitoring and reporting rather than continuous real-time monitoring. Event data is collected and associated at defined intervals or upon specific triggering events, reducing energy consumption while still providing timely performance feedback. The associator processes data periodically to generate performance reports without requiring constant system operation.

AI summary
A driver history report may include many factors to express performance or quality of driver service. Vehicle event recorders are coupled to systems which form an association between collected data and the vehicle operator in command of the vehicle at the event moment. Systems provide means for long-term storage of data particularly data in a structure which preserves the association between a driver and event records attributed to him. Special recall operations executed against stored data yields operator performance reporting—including a single value performance score indicative of a vehicle operator's performance and safety history. An analyzer system operates to recall data, particularly data from a plurality of events all associated with a single operator but recorded over an extended period of time. Data is arranged such that mathematical analysis may be applied independently to various data elements or data “fields” to produce performance metrics and ratios which reflect performance.
