Vehicle Voice Interaction State Adaptation

Solution Overview

Problem

Autonomous vehicles face challenges in voice interaction accuracy and privacy protection due to varying occupant and vehicle states, leading to decreased service request delivery and potential privacy invasions.

Innovation Solution

A voice interaction method that monitors real-time states of both the vehicle and occupant, using a personal terminal as an assisting device to adjust the presence and settings of voice interactions, ensuring accurate communication and privacy protection by activating or deactivating voice interactions based on these states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If voice interaction is continuously activated in autonomous vehicles, then occupant convenience is improved, but privacy invasion risk increases and voice recognition accuracy decreases due to varying occupant states

Engineering Contradiction:

Improveoccupant convenienceVSAvoidvoice recognition accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts voice interaction settings based on real-time monitoring of occupant states (sitting, standing, sleeping, etc.) and vehicle states. The voice interaction is activated or deactivated, and settings are modified according to the current state, making the system adaptive rather than static.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system continuously monitors occupant and vehicle states and uses this feedback to adjust voice interaction behavior. The monitoring results feed back into the control logic to determine whether voice interaction should be active and what settings should be applied, creating a closed-loop control system.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If voice interaction is activated regardless of occupant state, then service availability is improved, but privacy protection deteriorates as voice input content is exposed to other occupants

Engineering Contradiction:

Improveservice availabilityVSAvoidprivacy invasion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts voice interaction settings based on real-time monitoring of occupant states (sitting, standing, sleeping, etc.) and vehicle states. The voice interaction is activated or deactivated, and settings are modified according to the current state, making the system adaptive rather than static.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different voice interaction settings are applied based on the specific occupant state. When an occupant is in a private state (e.g., sleeping), the system applies stricter privacy protection settings or deactivates voice interaction entirely, while maintaining service availability when appropriate.

Inventive Principle:

Principle #3Local quality

3Device complexity

If voice interaction settings remain fixed, then system complexity is reduced, but voice interaction accuracy decreases according to varying occupant and vehicle states

Engineering Contradiction:

Improvesystem complexityVSAvoidvoice interaction accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts voice interaction settings based on real-time monitoring of occupant states (sitting, standing, sleeping, etc.) and vehicle states. The voice interaction is activated or deactivated, and settings are modified according to the current state, making the system adaptive rather than static.

Inventive Principle:

Principle #15Dynamics

AI summary

A voice interaction method and a vehicle using the same are disclosed. A voice interaction method according to an embodiment of the present invention activates a personal terminal through which a voice signal of an occupant is received as a voice interaction assisting device between the vehicle and the occupant and changes presence or absence of a voice interaction between the vehicle and the occupant and voice interaction settings according to states of the vehicle and the occupant.
