Vehicle Event Recorder Triggering Specialized Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle event recorders lack an efficient mechanism to trigger specialized data collection modes in response to external indications of anomalous events, such as dangerous driver behavior or route deviations, which limits their ability to quickly convey critical vehicle state data to a server for analysis.
Innovation Solution
A system that includes an input interface to receive external trigger indications, a processor to determine the necessity of entering a specialized data collection mode, and an output interface to instruct the vehicle event recorder to collect and transmit relevant data, such as video or sensor data, to a vehicle data server, which can initiate a specialized data collection mode based on external triggers like incorrect driver ID, dangerous behavior, or geozone deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle event recorder continuously monitors all sensor data, then complete event information is captured, but data transmission time and bandwidth consumption increase
Solution Approach 1:
The patent extracts and transmits only the specific sensor data elements relevant to the triggered event type, rather than transmitting all sensor data. The server requests only the necessary data subsets based on the event category, reducing transmission time while maintaining complete event information for analysis.
Solution Approach 2:
The system implements partial data collection by gathering only the specific sensor data needed for the particular event type that was triggered. This partial action approach reduces the overall data volume transmitted while ensuring all necessary information for that specific event is captured.
2Loss of information
If the vehicle event recorder transmits all sensor data immediately upon event detection, then complete information is available for analysis, but network bandwidth consumption increases
Solution Approach 1:
The system extracts and transmits only the specific sensor data elements relevant to the triggered event type. The server determines which data subsets are necessary based on the event category, extracting only what is needed for analysis rather than transmitting all available sensor data.
Solution Approach 2:
The patent changes the parameter of data transmission by implementing a selective data subset approach. Instead of transmitting all sensor data with uniform priority, the system adjusts the data transmission parameters to send only event-specific data elements, optimizing bandwidth usage while maintaining information completeness.
3Productivity
If the system implements a selective data collection mode triggered by external indications, then data transmission efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements a universal trigger mechanism that handles multiple event types and data subsets through a single coordinated system. The server-side trigger logic can recognize various event indications and appropriately request relevant data subsets, providing multi-functionality without requiring separate dedicated systems for each event type.
Solution Approach 2:
The server acts as an intermediary between the event detection system and the data collection system. The server receives trigger indications, determines the appropriate data subsets to request, and coordinates the selective data collection, thereby simplifying the overall system architecture while maintaining selective data collection efficiency.
Data Source
AI summary
A system for triggering a specialized data collection mode of a vehicle event recorder comprises an input interface, a processor, and an output interface. The input interface is configured to receive a trigger indication from an external trigger source. The processor is configured to determine whether the trigger indication comprises an indication to enter into a specialized data collection mode and, in the event that the trigger indication comprises the indication to enter into the specialized data collection mode, to determine a vehicle event recorder associated with the trigger indication. The output interface is configured to provide a specialized data collection mode indication to enter the specialized data collection mode to the vehicle event recorder in the event that the trigger indication comprises the indication to enter into the specialized data collection mode.
