Vehicle Voice Command Authentication Using Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle voice command systems require physical button activation and preprogrammed nomenclature, limiting authorization and natural language usage, especially when multiple occupants with varying authorization levels are present.
Innovation Solution
A vehicle command system using multi-modal technology for occupant authentication and natural language processing, combining voice and image recognition to determine authorized commands based on occupant identity and vehicle context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical button activation is required for voice commands, then system authorization control is improved, but ease of operation deteriorates and accessibility for all occupants worsens
Solution Approach 1:
The patent replaces the mechanical button-pressing system with an acoustic recognition system. The vehicle system captures voice commands through microphones and uses audio processing to identify authorized occupants, eliminating the need for physical button activation while maintaining authorization control through voice biometrics and occupant identification algorithms.
Solution Approach 2:
The patent introduces voice recognition technology as an intermediary between the occupant and the vehicle system. Instead of direct mechanical interaction, the voice command serves as a mediator that transmits the occupant's intent to the system while simultaneously verifying authorization through audio analysis and occupant identification.
2Measurement precision
If preprogrammed nomenclature is required for commands, then system control precision is improved, but adaptability to natural language deteriorates
Solution Approach 1:
The patent changes the parameter of command recognition from fixed preprogrammed nomenclature to dynamic natural language processing. The system processes varied speech patterns, dialects, and phrasings by converting audio signals into standardized command interpretations, maintaining accuracy through context-aware algorithms while accepting diverse natural language inputs.
Solution Approach 2:
The patent creates a universal command interface that handles multiple forms of expression for the same intent. The natural language processing system recognizes various ways occupants may phrase commands (e.g., 'open the window,' 'roll down the window,' 'lower the window') and translates them into standardized vehicle control actions, making the system adaptable to different speech styles while maintaining precise control.
3Device complexity
If uniform authorization is applied to all voice commands, then system simplicity is improved, but adaptability to different authorization levels deteriorates
Solution Approach 1:
The patent applies different authorization levels to different vehicle functions and occupants. The system identifies specific occupants through voice recognition and seat position detection, then applies appropriate authorization levels based on the function being accessed and the identified occupant's permissions, enabling fine-grained control without requiring complex manual configuration.
Data Source
AI summary
Systems and methods are disclosed herein for implementation of a vehicle command operation system that may use multi-modal technology to authenticate an occupant of the vehicle to authorize a command and receive natural language commands for vehicular operations. The system may utilize sensors to receive data indicative of a voice command from an occupant of the vehicle. The system may receive second sensor data to aid in the determination of the corresponding vehicular operation in response to the received command. The system may retrieve authentication data for the occupants of the vehicle. The system authenticates the occupant to authorize a vehicular operation command using a neural network based on at least one of the first sensor data, the second sensor data, and the authentication data. Responsive to the authentication, the system may authorize the operation to be performed in the vehicle based on the vehicular operation command.
