Vehicle Information Sampling for Lower Communication Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems collect vehicle information only when abnormalities occur, leading to insufficient vehicle operation verification and analysis, and result in excessive communication with vehicles.
Innovation Solution
An information collection system that includes a vehicle registration information acquisition unit, communication control unit, required number setting unit, information acquisition target vehicle extraction unit, and vehicle use information acquisition unit, which efficiently collects useful vehicle information by setting a required number of vehicles based on predetermined conditions and preferential extraction criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If information is transmitted from vehicle to system only when abnormality occurs, then communication amount is reduced, but vehicle operation verification and analysis become insufficient
Solution Approach 1:
The patent applies partial action by transmitting vehicle information selectively rather than continuously. The system determines presence/absence of abnormality and transmits only when abnormality is detected, or transmits a limited number of pieces of information even during normal operation. This resolves the contradiction by reducing communication amount while still collecting sufficient vehicle operation information for verification and analysis.
2Loss of information
If vehicle use information is collected from all vehicles, then comprehensive data is obtained, but communication load increases excessively
Solution Approach 1:
The system collects information from only a predetermined number of vehicles even when multiple abnormalities are detected. This partial action approach ensures comprehensive enough data for analysis while preventing excessive communication load by limiting the quantity of vehicles from which information is collected.
Solution Approach 2:
The patent applies local quality by differentiating information collection strategies based on abnormality conditions. When abnormalities are detected, the system collects information from a predetermined number of vehicles; when no abnormalities are detected, it collects information from fewer vehicles. This localized adaptation resolves the contradiction between data completeness and communication load.
