Server V2V Feedback for Redundant Data Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telematics systems, redundant information about vehicles that cannot communicate with a server is often transmitted, leading to inefficiencies in data processing and increased resource consumption, which can hinder autonomous driving capabilities.
Innovation Solution
A system comprising a server, first vehicle, and second vehicle that communicates to prevent the transmission of redundant information by detecting when a third vehicle cannot communicate with the server and sending a message to the second vehicle to cease data transmission, utilizing sensors and communication modules for Vehicle-to-Vehicle (V2V) communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicles continuously transmit information about all sensed vehicles to the server, then the server receives comprehensive data for autonomous driving, but redundant information about vehicles that cannot communicate with the server increases data traffic and processing overhead
Solution Approach 1:
The server performs preliminary identification of vehicles that cannot communicate with the server based on reception status information. This preliminary action allows the server to proactively notify other vehicles to stop transmitting information about these non-communicating vehicles, preventing redundant data transmission before it occurs
Solution Approach 2:
The system implements a feedback mechanism where the server sends notifications to vehicles about which vehicles cannot communicate with the server. This feedback loop enables vehicles to adjust their information transmission behavior based on server instructions, reducing redundant data while maintaining necessary information flow
2Reliability
If the server processes all transmitted information from multiple vehicles, then comprehensive vehicle data is available, but server resources are wasted processing duplicate information about the same vehicles
Solution Approach 1:
The server performs preliminary filtering by identifying vehicles that cannot communicate with the server and notifying other vehicles to stop transmitting information about them. This preliminary action prevents duplicate data from reaching the server, improving processing efficiency while maintaining data accuracy for vehicles that can communicate
Solution Approach 2:
The system extracts and removes redundant information transmission by notifying vehicles to stop sending data about non-communicating vehicles. This extraction of unnecessary data transmission reduces server processing load while preserving essential information about vehicles that can communicate with the server
3Loss of information
If vehicles transmit information about all detected vehicles, then complete situational awareness is achieved, but energy consumption increases due to redundant transmission
Solution Approach 1:
Vehicles receive feedback from the server indicating which vehicles cannot communicate with the server. Based on this feedback, vehicles can stop transmitting information about these non-communicating vehicles, reducing communication energy consumption while maintaining situational awareness through continued transmission of information about vehicles that can communicate
Solution Approach 2:
The server provides preliminary information to vehicles about which vehicles cannot communicate with the server. This preliminary action enables vehicles to proactively reduce transmission of redundant information, conserving energy while maintaining necessary situational awareness
Data Source
AI summary
A server includes: a receiver configured to receive information, from a first vehicle, indicating that a third vehicle is unable to communicate with the server; and a transmitter configured to transmit a message, to a second vehicle that is able to sense the third vehicle, indicating that it is unnecessary to transmit information about the third vehicle, in response to the receiver receiving the information indicating that the third vehicle is unable to communicate with the server.
