Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Transmitting all support information to support target vehicles increases communication load and may not be effective due to unstable behavior detection in existing information processing systems.

Innovation Solution

An information processing system that transmits support information only when the area corresponding to the support target vehicle is in a moving body encounter situation, determined by calculating the total number and staying number of moving objects in predefined areas, using target vehicle data and object detection information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all support information is transmitted to support target vehicle, then support completeness is improved, but communication load increases

Engineering Contradiction:

Improvesupport information completenessVSAvoidcommunication load

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system transmits support information selectively rather than completely. The transmission is triggered only when the estimated probability of unstable behavior exceeds a predetermined threshold, meaning only partial information transmission occurs when necessary, reducing overall communication load while maintaining adequate support coverage

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If support information is transmitted frequently, then support effectiveness is improved, but communication load increases

Engineering Contradiction:

Improvesupport effectivenessVSAvoidcommunication load

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system uses periodic evaluation of transmission necessity based on probability thresholds. Instead of continuous or frequent transmission, the system periodically assesses whether transmission is needed by comparing the estimated probability of unstable behavior against a threshold, creating a rhythmic, conditional transmission pattern that balances effectiveness with load reduction

Inventive Principle:

Principle #19Periodic action

3Loss of energy

If support information is transmitted only when probability threshold is exceeded, then communication load is reduced, but support information completeness may be insufficient

Engineering Contradiction:

Improvecommunication loadVSAvoidsupport information completeness

Core Design Contradiction:

Loss of energyVSLoss of information

Solution Approach 1:

The system changes the parameter of transmission timing based on probability thresholds. By monitoring the estimated probability of unstable behavior and comparing it against a predetermined threshold, the system dynamically determines when transmission should occur, optimizing the balance between communication load and information completeness through parameter-based decision making

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processing system for transmitting support information to a support target vehicle based on target vehicle data, the information processing system comprising: a moving body encounter situation estimating unit that estimates whether or not a situation of the area is a moving object encounter situation based on target vehicle data in a preset area; and a vehicle support unit that transmits support information to the support target vehicle when a situation of an area in which the support target vehicle is located is a moving object encounter situation, and does not transmit support information to the support target vehicle when a situation of an area in which the support target vehicle is located is not a moving object encounter situation.
