Vehicle Communication Control for Abnormal-Situation Data Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face pressure on communication lines and power consumption during abnormal situations like natural disasters or accidents, which can strain fundamental facilities.
Innovation Solution
A vehicle equipped with an in-vehicle communication device that restricts data communication based on predefined communication conditions received from a server apparatus, allowing it to reduce data transmission and search for alternatives, thereby conserving power and communication resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous distributed network communication is used during abnormal situations, then communication capability is maintained, but pressure on communication lines and power consumption increases
Solution Approach 1:
The patent applies partial action by selectively transmitting only essential data during abnormal situations. The communication control device determines whether to transmit data based on abnormality information, transmitting only when necessary (e.g., when abnormality occurs in a specific direction or affects vehicle operation). This reduces overall communication frequency and power consumption while maintaining critical communication capabilities.
Solution Approach 2:
The patent changes communication parameters dynamically based on abnormality conditions. The communication control device adjusts transmission behavior by comparing abnormality information with predetermined conditions, changing parameters such as transmission frequency, data type, and communication mode. This allows the system to maintain reliability when needed while reducing power consumption during normal operations.
