Solution Overview

Problem

Existing vehicle-to-vehicle communication systems face challenges in smoothly promoting the giving action, such as lane changes or merging, due to inefficiencies in token exchange mechanisms.

Innovation Solution

A control device for vehicles is developed, incorporating a control unit, communication unit, and storage unit, which sets the vehicle to a token-related mode and facilitates token exchange between vehicles via communication, thereby promoting smooth giving actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If token exchange mechanisms are used to promote giving actions in vehicle-to-vehicle communication, then the motivation for giving way is improved, but the smoothness of promoting the giving action deteriorates

Engineering Contradiction:
Improvemotivation for giving actionVSAvoidsmoothness of giving action
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control device determines in advance whether the own vehicle should be given way based on travel direction, position, and lane information before the actual giving action occurs. This preliminary determination simplifies the real-time decision-making process and makes the token exchange mechanism more efficient by pre-identifying giving scenarios.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the driver through output devices (displays, speakers) when a giving action is determined necessary. This feedback loop allows the driver to understand why the giving action is being prompted and creates a more transparent and smooth interaction between the system and user.

Inventive Principle:
Principle #23Feedback

2Reliability

If complex token exchange protocols are implemented, then the reliability of vehicle communication is improved, but the complexity of the communication system increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcommunication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control device separates the giving action determination process from the token exchange mechanism. The determination unit handles the complex logic of when giving is needed based on vehicle data, while the communication unit simply executes the token exchange based on determined results, dividing the system into manageable functional segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control device acts as an intermediary between the vehicle's operational data and the token exchange system. It processes raw vehicle data (position, lane, direction) and translates it into meaningful giving action determinations, mediating between the physical vehicle operations and the digital token economy.

Inventive Principle:
Principle #24Intermediary (Mediator)
