Vehicle Traffic Scene Parameter Conversion for Lower Server Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing software update systems face significant processing loads and congestion issues due to the large data size of traffic scene information collected from vehicles, especially with the widespread adoption of advanced driving support systems, which can lead to network and server overload, and the need for efficient data reduction is essential.
Innovation Solution
An information processing apparatus that aggregates and simulates vehicle-specific scene information, determines scene adaptation, and converts it into smaller parameters for traffic scene reproduction, reducing data size and processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the interval of time steps to be recorded is short and the entire recording time is long, then the accuracy of traffic scene information is improved, but the data size increases
Solution Approach 1:
The patent extracts and transmits only essential traffic scene information (problem scene data) rather than complete continuous data. The system identifies and extracts key events and parameters from the traffic scene, transmitting only this extracted information to the server, thereby reducing data size while maintaining accuracy for problem analysis.
Solution Approach 2:
The patent segments the continuous traffic scene data into discrete problem scenes based on detected problems. Instead of transmitting all continuous data at short time intervals, the system divides the data into meaningful segments (problem scenes) and transmits only these segmented portions, reducing overall data volume while preserving essential information.
2Adaptability or versatility
If the number of vehicles connected to the server increases, then the coverage of traffic scene collection is improved, but the processing load on network and server increases
Solution Approach 1:
The patent applies data extraction at the vehicle end before transmission. Each vehicle extracts and transmits only essential problem scene information rather than complete traffic scene data. This extraction process significantly reduces the data volume that needs to be transmitted and processed by the server, enabling the system to handle a larger number of connected vehicles without proportionally increasing network and server processing loads.
3Duration of action of moving object
If the entire recording time is long, then the completeness of traffic scene information is improved, but the data size increases
Solution Approach 1:
The patent segments long recording periods into discrete problem scenes based on detected traffic problems. Instead of transmitting all data throughout the entire recording period, the system identifies specific problem scenes within the recording period and transmits only data related to these segmented problem events, maintaining completeness for problem analysis while reducing overall data size.
Solution Approach 2:
The patent extracts only the essential problem scene data from the entire recording period. The system identifies and extracts information related to detected problems (accidents, near misses, traffic violations) from the long recording period, transmitting only this extracted problem-related information rather than all continuous data, thereby reducing data size while maintaining completeness for problem analysis.

AI summary
An information processing apparatus in an information collection system that collects information from a plurality of vehicles, the information processing apparatus including: a receiving unit that receives specific scene information including scene type data, sensor data, control data, and position data; a scene adaptation determination unit that performs simulation of a behavior of the vehicle on the basis of the received specific scene information and determines whether or not a result of the simulation adapts to a traffic scene indicated by the scene type data; a parameter conversion unit that converts the specific scene information determined that a result of the simulation adapts to the traffic scene and generates a parameter for reproducing the traffic scene in another information processing apparatus; and a transmission unit that transmits the generated parameter to the another information processing apparatus.
