Solution Overview

Problem

Conventional driving assistance systems may impair driver skills due to overdependence and fail to provide comprehensive feedback on vehicle behavior, leading to inefficiencies in fuel consumption and increased risk of accidents.

Innovation Solution

A driving skill improvement device that detects a driver's operation state and vehicle motion, computes an acceleration indicator, and presents information to the driver to improve skills through a combination of drive assist, information, and evaluation modes, allowing drivers to select the most suitable mode for their needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If driving assistance systems automatically control inter-vehicle distance and driving within lanes, then driving load of driver is reduced, but driving skill of driver is impaired due to system overdependence

Engineering Contradiction:
Improvedriving loadVSAvoiddriving skill
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system provides real-time feedback to the driver through presentation of acceleration indicators and driving state information. This feedback mechanism allows drivers to understand the relationship between their operations and vehicle behavior, maintaining skill development while benefiting from assistance systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables drivers to self-evaluate their driving skills through presentation of objective driving information and acceleration indicators. Drivers can independently assess their performance and improve their skills without external intervention, maintaining autonomy while reducing driving load.

Inventive Principle:
Principle #25Self-service

2Device complexity

If driving assistance systems provide limited information on deceleration before curves, then system complexity is reduced, but comprehensive feedback on vehicle behavior is insufficient

Engineering Contradiction:
