In-Vehicle Voice Control Override by Occupant Authority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle speech control systems lack the ability to effectively restrict unintended operations, such as mischievous or erroneous actions, by children or other occupants.
Innovation Solution
A control apparatus that detects voices uttered by multiple occupants in a vehicle and controls vehicle functions based on these voices. The apparatus determines the attributes of the occupants who utter activation and cancellation commands, allowing it to interrupt the control if a higher authority occupant issues a cancellation command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech control is allowed for all occupants, then ease of operation is improved, but unintended operations by children or less dominant occupants cannot be restricted
Solution Approach 1:
The system applies preliminary anti-action by detecting cancellation speech from other occupants before the control function is fully executed. When cancellation speech is detected, the system interrupts and prevents the activation of the control function, thereby counteracting potential unintended operations before they can cause harm.
Solution Approach 2:
The control apparatus acts as an intermediary between speech input and function activation. It introduces an intermediate verification step that checks for cancellation speech from other occupants with higher dominance, mediating between the desire for easy speech-based operation and the need to prevent unintended operations.
2Object-affected harmful factors
If cancellation is allowed for any occupant, then unintended operations can be restricted, but conflicts between multiple occupants may occur
Solution Approach 1:
The system applies local quality by assigning different dominance levels to different occupants based on their attributes (e.g., adult vs. child). This creates a hierarchical structure where cancellation rights are localized to specific occupants with higher dominance, allowing restriction of unintended operations while avoiding conflicts by clearly defining who can override whom.
3Object-affected harmful factors
If attribute-based restriction is applied, then unintended operations can be prevented, but operations by legitimate users may be interrupted
Solution Approach 1:
The system applies dynamics by making the cancellation authority dynamic rather than static. Instead of permanently restricting certain occupants, the system dynamically evaluates cancellation requests in real-time based on the relative dominance attributes of the initiating and canceling occupants, ensuring that legitimate operations are not interrupted while still preventing unintended ones.

AI summary
A control apparatus includes a controller that, upon detecting a first voice having been uttered by a first occupant, among occupants, as a command to activate a function, determines, as a first attribute, an attribute of the first occupant, upon detecting, after the first voice has been detected and before the function is activated, a second voice that is different from the first voice and has been uttered as a command to cancel the activation of the function, determines, as a second attribute, an attribute of a second occupant who has uttered the second voice, and determines, according to the result of a comparison between the first and second attributes, whether to interrupt control to be performed based on the first voice.
