Hierarchical Driver Identification for Real-Time Safety Event Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for real-time safety event detection in vehicles face inefficiencies and inaccuracies due to the need to process and store large volumes of data from diverse driver assignment sources, leading to delays in identifying the correct driver associated with the event.
Innovation Solution
A driver identification module that utilizes a hierarchical plurality of driver assignment categories, combining sensor and non-sensor data sources to efficiently and accurately identify the driver by prioritizing data based on assignment categories, reducing the time required to associate safety events with the correct driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data from diverse driver assignment sources is processed to identify the driver associated with a safety event, then measurement precision of driver identification is improved, but loss of time in determining the driver increases
Solution Approach 1:
The patent segments driver assignment data into multiple hierarchical categories (e.g., primary assignment sources, secondary assignment sources, tertiary assignment sources). Each category contains specific data types from diverse sources such as telematics devices, mobile devices, and vehicle systems. This segmentation allows the system to process and evaluate different data sources independently, improving identification accuracy by systematically comparing categorized data while managing processing time through structured hierarchy.
2Loss of time
If simple alerts are used for real-time safety events, then loss of time in providing alerts is reduced, but measurement precision of driver identification deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-processing and categorizing driver assignment data into hierarchical structures before safety events occur. The system establishes predetermined categories and data sources in advance, so that when a safety event is detected, the system can quickly query pre-organized data rather than processing raw data from multiple sources in real-time. This enables faster alert response while maintaining accurate driver identification through the pre-established hierarchical framework.
3Measurement precision
If comprehensive data from multiple driver assignment sources is collected, then measurement precision of driver identification is improved, but device complexity increases
Solution Approach 1:
The patent introduces a hierarchical categorization dimension to organize driver assignment data from multiple sources. Instead of treating all data sources as a single complex set, the system adds a categorical dimension with multiple levels (primary, secondary, tertiary assignment sources). This dimensional organization simplifies the processing logic by providing a structured framework for evaluating data from diverse sources, reducing system complexity while maintaining comprehensive data collection for accurate driver identification.
Data Source
AI summary
A management server system may obtain data associated with a vehicle. The management server system may obtain the data from a plurality of data sources associated with the vehicle. The data may include a plurality of subsets of data that each correspond to correspond to a particular driver assignment category. Each subset of data may identify a particular persona as a driver of a vehicle. The management server system may determine a driver of the vehicle based on each subset of data and a hierarchical plurality of driver assignment categories. Based on the determination of the driver of the vehicle, the management server system can dynamically map the driver to a particular event. The management server system may generate a user interface identifying the driver and the event.
