Solution Overview

Problem

Conventional speech recognition systems in vehicles fail to provide customized services to multiple passengers, often outputting incorrect results or performing actions based on a single passenger's input, neglecting the preferences of others.

Innovation Solution

A vehicle control apparatus and method that recognizes passengers through weight sensors and cameras, activates microphones and speakers based on age, and provides customized services by re-querying each passenger based on their speech recognition results, ensuring each passenger receives intended services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional speech recognition system processes voice query from one passenger, then system simplicity is maintained, but service customization for multiple passengers deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidservice customization

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system segments the service processing by identifying individual passengers and their respective preferences. It divides the service domain into passenger-specific segments, allowing customized service delivery to each passenger based on their identified preferences without requiring complete system redesign.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-storing preferences for multiple passengers before service delivery. When a voice query is received, the system has already prepared passenger identification data and preference information, enabling rapid customization without adding complex real-time processing.

Inventive Principle:

Principle #10Preliminary action

2Speed

If speech recognition result is applied immediately without additional query, then response speed is improved, but service accuracy for multiple passengers deteriorates

Engineering Contradiction:

Improveresponse speedVSAvoidservice accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The system implements feedback by querying other passengers after initial speech recognition. This feedback mechanism allows the system to verify whether the recognized voice query and intended service match other passengers' preferences, improving service accuracy while maintaining relatively fast response through selective querying.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system applies partial action by selectively querying only when multiple passengers are present and when service customization is needed. It avoids excessive full-system queries by applying the additional query mechanism only in specific scenarios, thus balancing response speed and accuracy.

Inventive Principle:

Principle #16Partial or excessive action

3Adaptability or versatility

If additional queries are performed for each passenger, then service customization is improved, but system complexity increases

Engineering Contradiction:

Improveservice customizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements self-service by using automatically captured passenger data (weight sensor information, face recognition results) to identify passengers and retrieve their preferences without manual input. This reduces system complexity by eliminating the need for complex passenger registration and manual preference setting mechanisms.

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If passenger identification through weight sensor and camera is implemented, then service personalization is improved, but device complexity increases

Engineering Contradiction:

Improveservice personalizationVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system applies universality by using weight sensors and cameras for multiple purposes: passenger presence detection, passenger identification, and preference retrieval. These devices serve universal functions across different service scenarios, reducing the need for specialized equipment and lowering overall system complexity despite enhanced personalization capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A vehicle control apparatus and method use speech recognition and include: a passenger recognizing device configured to recognize passengers including a first passenger and at least one second passenger in a vehicle; a voice recognizing device configured to receive and to recognize a voice utterance by the first passenger or the at least one second passenger and to output a speech recognition result based on the received voice utterance; and a processor configured to additionally query the at least one second passenger or the first passenger based on the speech recognition result of the voice utterance of the first passenger or the at least one second passenger, respectively, to provide each of the first passenger and the at least one second passenger with a customized service.
