Solution Overview

Problem

Automatic driving technologies fail to consider the state of the vehicle cabin, leading to monotonous and uncomfortable driving experiences for passengers, as they do not allow diverse driving styles that cater to passenger preferences or circumstances.

Innovation Solution

An automatic driving assistance device that acquires information on the vehicle cabin state using cameras and audiovisual systems, modifying traveling characteristics such as acceleration, deceleration, and steering to enhance passenger comfort, including features like earlier braking, slow acceleration, and quiet operation based on passenger presence and activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automatic driving is implemented without considering cabin state, then automation level is improved, but passenger comfort and hospitality deteriorate

Engineering Contradiction:

Improveautomatic driving capabilityVSAvoidadaptability to passenger preferences and circumstances

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The automatic driving control device dynamically adjusts traveling characteristics (acceleration, deceleration, steering) based on real-time cabin state information detected by various sensors. This allows the system to adapt its driving behavior to different passenger conditions, such as providing gentler acceleration when passengers are sleeping or present infants, thereby resolving the contradiction between high automation and adaptability to passenger needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback by continuously monitoring cabin state through sensors (camera, microphone, temperature sensors) and using this information to adjust driving characteristics. The detected cabin state feeds back to the automatic driving control device, which modifies traveling parameters accordingly, enabling the system to maintain both high automation and responsiveness to passenger circumstances.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If diverse driving styles are allowed in manual driving, then passenger comfort is improved, but driving operation complexity increases

Engineering Contradiction:

Improvediverse driving stylesVSAvoiddriver operation requirements

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The automatic driving control device performs the function of selecting and adjusting driving characteristics based on cabin state without requiring driver intervention. The system serves itself by automatically detecting passenger conditions and modifying traveling parameters accordingly, eliminating the need for drivers to manually adjust settings while still providing diverse, comfortable driving styles.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces manual driver operations with automated electronic control. Instead of requiring drivers to physically adjust driving behavior based on passenger needs, the electronic automatic driving control device substitutes mechanical driver actions with automated sensor-based detection and control algorithms, providing diverse driving styles without increasing operational complexity for the driver.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If standard automatic driving control is used, then system simplicity is improved, but passenger hospitality and comfort deteriorate

Engineering Contradiction:

Improvecontrol system structureVSAvoidresponse to cabin conditions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The automatic driving control device integrates multiple functions within a single system: it performs standard automatic driving control while simultaneously detecting cabin state and adjusting traveling characteristics. This multi-functional approach allows the system to maintain relative simplicity while providing adaptive response to various cabin conditions, resolving the contradiction between system simplicity and hospitality capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs preliminary detection of cabin state conditions and proactively adjusts traveling characteristics before passengers experience discomfort. By detecting conditions such as sleeping passengers or infants in advance and preemptively modifying acceleration and deceleration patterns, the system provides enhanced hospitality without requiring complex real-time reactions, thereby maintaining system simplicity while improving comfort.

Inventive Principle:

Principle #10Preliminary action
