Driving Support Setting Approval After Voice Recognition Requests

Solution Overview

Problem

Existing setting change assist apparatuses for driving support control in vehicles may erroneously change settings due to incorrect voice recognition, leading to unintended changes in driving support control states.

Innovation Solution

A setting change assist apparatus that performs voice recognition, notifies the driver of potential changes, and requires explicit approval operations through specific vehicle controls to confirm and execute setting changes, thereby preventing erroneous changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If voice recognition processing is used to change setting state, then ease of operation is improved, but reliability deteriorates due to erroneous recognition

Engineering Contradiction:

Improveease of operationVSAvoidreliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The notification device provides feedback to the driver by displaying confirmation information about the recognized setting change request. This allows the driver to verify whether the voice recognition was correct before the setting state is actually changed, thereby maintaining ease of operation while improving reliability through error detection and correction.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary voice recognition processing and displays the recognized content to the driver before actually changing the setting state. This preliminary action allows the driver to confirm the accuracy of voice recognition, preventing erroneous changes while maintaining convenient voice-based operation.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If voice recognition processing is used to change setting state, then productivity is improved, but measurement precision deteriorates due to recognition errors

Engineering Contradiction:

ImproveproductivityVSAvoidmeasurement precision

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The notification device provides feedback to the driver by displaying confirmation information about the recognized setting change request. This allows the driver to verify whether the voice recognition was correct before the setting state is actually changed, thereby maintaining ease of operation while improving reliability through error detection and correction.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary voice recognition processing and displays the recognized content to the driver before actually changing the setting state. This preliminary action allows the driver to confirm the accuracy of voice recognition, preventing erroneous changes while maintaining convenient voice-based operation.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If confirmation information is displayed requiring approval operation, then reliability is improved, but device complexity increases

Engineering Contradiction:

ImprovereliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The notification device serves multiple functions: it notifies the driver of setting change requests, displays confirmation information, and receives approval operations. By making the notification device multi-functional, the system improves reliability through confirmation without adding separate dedicated components, thereby minimizing the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Provided is a setting change assist apparatus for a vehicle configured to: determine whether a setting change request for changing a setting state of driving support control is issued; when determining that the setting change request is issued, notify a driver of confirmation information including information on a content of the setting change request and information on a predetermined approval operation with respect to the setting change request; and change the setting state of the driving support control in accordance with the setting change request when the driver performs the approval operation.
