Real-Time Event Data Capture for Autonomous Vehicle Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient and robust system and method to support real-time review of events associated with the operation of an autonomous vehicle in various scenarios, as existing technologies require waiting for the vehicle to complete its operational run and return to a facility for data upload and analysis.
Innovation Solution
A system and method that provide a framework for specifying triggers indicating incident occurrences and automatically capturing and uploading specific data sets in real-time as an autonomous vehicle operates, allowing for immediate access and review of relevant data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is uploaded and analyzed only after the vehicle returns to a facility, then data completeness is improved, but review time is worsened
Solution Approach 1:
The patent segments the data upload and review process into two modes: real-time upload of selected event data during vehicle operation, and comprehensive upload of all data when the vehicle returns to the facility. This allows partial data to be reviewed immediately while maintaining the option for complete data analysis later, thus resolving the contradiction between data completeness and review time.
2Productivity
If all sensor data is uploaded in real-time, then review speed is improved, but data transmission volume is worsened
Solution Approach 1:
The patent extracts and uploads only selected event data (specific sensor readings related to particular events of interest) in real-time, rather than uploading all sensor data. This extraction approach enables fast review of relevant events while minimizing data transmission volume, thus resolving the contradiction between review speed and data transmission volume.
3Loss of time
If real-time data upload is implemented, then event analysis speed is improved, but system complexity is worsened
Solution Approach 1:
The patent implements a dynamic data upload system that can switch between real-time upload mode (for events of interest) and batch upload mode (when the vehicle returns to the facility). This dynamic approach allows the system to optimize between fast event analysis and reduced system complexity by adjusting the upload frequency and data volume based on operational context.

AI summary
A system and method including receiving an indication of an occurrence of an event associated with the operation of an autonomous vehicle; determining at least one action to be performed, the at least one action including a data request for a specified subset of stored data associated with the operation of the autonomous vehicle from a memory; generating an output including the specified subset of data; and transmitting the specified subset of data to a remote monitoring system.
