Solution Overview

Problem

Existing vehicle travel control systems limit the reflection of user preference in determination data, leading to potential delays in activating the erroneous operation suppressing function.

Innovation Solution

An electronic control device that includes a travel experience determination unit, collective knowledge storage unit, empirical knowledge storage unit, combination ratio determination unit, and data generation unit, which combine collective knowledge information and empirical knowledge information based on travel experience and a determined combination ratio to generate control data for the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If collective knowledge information and empirical knowledge information are combined at a unique fixed ratio, then the system can provide consistent determination data, but the system cannot adequately reflect user preference and may delay activation of the erroneous operation suppressing function

Engineering Contradiction:

Improvereflection of user preferenceVSAvoidactivation timing of erroneous operation suppressing function

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The combination ratio determination unit dynamically adjusts the combination ratio between collective knowledge information and empirical knowledge information based on travel experience and travel environment. As the vehicle accumulates more travel experience at a particular location, the ratio shifts to emphasize empirical knowledge information, enabling the system to adapt to user preferences while maintaining safety through collective knowledge when experience is limited.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of combination ratio based on travel experience and travel environment. By modifying this parameter dynamically, the system can emphasize either collective knowledge information (for safety) or empirical knowledge information (for user preference) according to the specific situation, resolving the contradiction between reliability and adaptability.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If determination data is set to reflect user preference, then convenience is improved, but the activation timing of the erroneous operation suppressing function is delayed

Engineering Contradiction:

Improveuser preference reflectionVSAvoidactivation timing delay

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system dynamically adjusts the balance between collective knowledge and empirical knowledge based on travel experience. When travel experience is insufficient, collective knowledge is emphasized to ensure timely activation of safety functions. When travel experience is sufficient, empirical knowledge is emphasized to reflect user preference, thus reducing perceived delay while maintaining safety.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the erroneous operation suppressing function is activated based on collective knowledge alone, then safety is ensured, but user preference and convenience are not reflected

Engineering Contradiction:

Improvesafety of erroneous operation suppressing functionVSAvoiduser preference reflection

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system merges collective knowledge information from multiple vehicles with empirical knowledge information from the own vehicle's travel history. By combining these two types of knowledge with a dynamically adjusted ratio, the system simultaneously ensures safety through collective knowledge and reflects user preference through empirical knowledge, resolving the contradiction between reliability and ease of operation.

Inventive Principle:

Principle #5Merging (Combining)
