Vehicle Terminal Data Transmission Control via V2V Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent transportation systems, vehicles transmit similar data to a traffic information center, leading to data overload and inefficiency due to individual data transmission, causing server malfunctions and inefficient data sending.
Innovation Solution
A vehicle terminal that collects driving information, uses vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication to compare and share data, controlling data transmission by transmitting only unique information within an allowable error range, thereby reducing data overload and improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each vehicle transmits its individually collected driving information to the traffic information center, then each vehicle can independently contribute data, but the server experiences data overload and malfunction due to redundant similar information from vehicles performing group driving
Solution Approach 1:
The patent merges data from multiple vehicles by having the traffic information center collect driving information from multiple vehicles and identify similar information patterns. When similarity exceeds a threshold, the system combines these similar data points into a single representative data set, thereby reducing redundant transmissions to the server while maintaining data coverage.
Solution Approach 2:
The patent extracts only the unique or significantly different portions of driving information for transmission. By comparing data across vehicles and identifying similarities, the system extracts and transmits only the necessary unique data elements, leaving redundant similar information to be represented by other vehicles' transmissions.
2Ease of operation
If vehicles transmit individually collected information to the server, then data collection is simple and direct, but data transmission becomes inefficient with overlapping redundant data being sent multiple times
Solution Approach 1:
The patent implements a feedback mechanism where the traffic information center continuously monitors and compares driving information from multiple vehicles. This feedback loop enables the system to identify similar information patterns and adjust transmission decisions dynamically, preventing redundant transmissions while maintaining operational simplicity for individual vehicles.
Solution Approach 2:
The traffic information center serves multiple functions: it collects data from vehicles, performs similarity comparison analysis, identifies redundant information patterns, and manages transmission decisions. This multi-functional approach maintains ease of operation for individual vehicles while significantly improving overall data transmission efficiency through centralized intelligence.

AI summary
A vehicle terminal includes a data collector for collecting driving information of a vehicle, a first communicator for performing wireless communication with other vehicle terminals, a second communicator for performing wireless communication with roadside terminals positioned at roadsides, and a controller for generating corresponding vehicle transmission data using the driving information, wherein the controller compares other vehicle transmission data provided from the other vehicle terminals and the corresponding vehicle transmission data with each other and transmits identification information assigned to the corresponding vehicle transmission data through the second communicator when an error between the other vehicle transmission data and the corresponding vehicle transmission data is within an allowable error range.
