Driving Support Setting Confirmation for Voice Recognition Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing setting change assist apparatuses for vehicle driving support control may erroneously change the setting state due to incorrect voice recognition, leading to unintended changes in driving support control settings.
Innovation Solution
A setting change assist apparatus that includes a controller for voice recognition, an operating device for driver input, and a notification device to confirm setting change requests, ensuring that the driver approves intended changes before altering the setting state, thereby preventing erroneous changes.
Engineering Contradictions & Design Principles
Engineering 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
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, resolving the contradiction by maintaining ease of voice-based operation while improving reliability through driver verification
Solution Approach 2:
The system performs preliminary action by notifying the driver of the setting change request before actually changing the setting state. The notification device displays confirmation information in advance, allowing the driver to confirm or cancel the requested change, thus preventing erroneous changes while maintaining voice recognition convenience
2Reliability
If confirmation information is displayed before setting change, then reliability is improved, but loss of time increases due to additional confirmation step
Solution Approach 1:
The system applies partial action by only requiring confirmation when a setting change is requested through voice recognition. The notification device displays confirmation information selectively based on the type of setting change request, rather than requiring confirmation for all operations, thus improving reliability while minimizing time loss

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.
