Solution Overview

Problem

Existing on-vehicle systems face challenges in efficiently requesting and communicating image captures of target spots between vehicles located in remote places via direct wireless communication, particularly in forming effective inter-vehicle networks for image sharing.

Innovation Solution

The system enables vehicles to perform vehicle-to-vehicle direct communication using technologies like 700 MHz and 5.8 GHz bands, forming an inter-vehicle network to request and transmit image captures of target spots, with vehicles determining their proximity and capability to capture images based on predefined ranges and 3D map data, ensuring efficient image sharing even when direct capture is not possible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If direct wireless communication between vehicles is used for image capture requests and transmission, then communication speed and efficiency are improved, but communication reliability deteriorates when vehicles are in remote locations

Engineering Contradiction:

Improvecommunication speedVSAvoidcommunication reliability

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent introduces intermediate vehicles as mediators in the communication path. When a requesting vehicle cannot directly communicate with the target vehicle, the system automatically routes requests through intermediate vehicles that can relay data between the two parties, ensuring communication reliability while maintaining efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the communication path into multiple hops through intermediate vehicles. Instead of requiring a single direct connection, the communication is divided into multiple segments that can be transmitted through different vehicles, improving reliability in remote areas where direct communication may fail

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple intermediate vehicles are used to relay communication requests, then communication coverage is improved, but communication delay increases

Engineering Contradiction:

Improvecommunication coverageVSAvoidcommunication delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent dynamically selects intermediate vehicles based on real-time conditions such as vehicle location, communication status, and proximity to the target. The system adapts the number and identity of intermediaries used, minimizing relay hops when possible to reduce delay while maintaining coverage when direct communication is unavailable

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where intermediate vehicles report their status and the system continuously optimizes the relay path. This allows the system to learn from communication experiences and select the most efficient intermediate vehicles, reducing delay while maintaining broad coverage

Inventive Principle:

Principle #23Feedback

3Productivity

If vehicles continuously broadcast request information, then image capture capability is improved, but energy consumption increases

Engineering Contradiction:

Improveimage capture capabilityVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic broadcasting instead of continuous broadcasting. Vehicles broadcast request information at predetermined intervals, which maintains image capture capability by ensuring requests are transmitted regularly while significantly reducing energy consumption compared to continuous transmission

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system enables vehicles to self-manage their broadcasting behavior based on their own state and needs. Vehicles adjust their broadcasting frequency and timing based on their current requirements, reducing unnecessary transmissions and optimizing energy usage while maintaining capture capability

Inventive Principle:

Principle #25Self-service

AI summary

A control device is provided, including a request-information receiving section that receives request information being for requesting transmission of a captured image of an image-capturing target spot and including spot location information indicating the image-capturing target spot and transmitting source information indicating a transmitting source of the request information; a vehicle location information acquiring section that acquires vehicle location information indicating a location of the first vehicle; and a transmission control section that transmits, to the transmitting source indicated by the transmitting source information, a captured image of the image-capturing target spot captured by an image capturing section included in the first vehicle when the first vehicle is located within a predetermined range with the image-capturing target spot as a reference, and broadcasts the request information to a vehicle other than the first vehicle when the first vehicle is located outside the predetermined range, based on the vehicle location information.
