Vehicle Control Device Voice Passenger Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack the ability to efficiently identify and authenticate passengers, leading to insecure access to personal information and vehicle functions, especially in shared vehicle scenarios where multiple users are involved.
Innovation Solution
A vehicle control device that utilizes voice recognition to identify passengers and customize user interfaces, allowing only authorized individuals to access personal information and vehicle functions without additional authentication processes, while enabling multiple passengers to control vehicle features through voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If voice recognition is used to identify passengers, then authentication speed and convenience are improved, but security against unauthorized access may be worsened
Solution Approach 1:
The patent combines multiple authentication methods (voice recognition, fingerprint recognition, and RFID card recognition) into a single integrated authentication system. The controller can select from multiple authentication results to determine whether to authenticate a user, thereby maintaining both speed and security by merging different biometric and cryptographic verification mechanisms.
Solution Approach 2:
The patent changes the authentication parameters by using different authentication methods for different scenarios. The controller can switch between voice recognition (fast but less secure), fingerprint recognition (moderate speed and security), and RFID card recognition (slow but highly secure with cryptographic verification), thereby adapting the security level to the specific access situation while maintaining authentication efficiency.
2Reliability
If multiple authentication methods are integrated, then security is improved, but device complexity is worsened
Solution Approach 1:
The controller serves multiple functions by being capable of performing voice recognition, fingerprint recognition, and RFID card recognition, as well as selecting from these different authentication results. This multi-functional design allows the system to maintain high security through multiple authentication methods while avoiding the need for separate control units for each method, thereby reducing overall system complexity.
3Ease of operation
If personalized user interfaces are provided, then user experience is improved, but information security risks are worsened
Solution Approach 1:
The system performs preliminary authentication (through voice, fingerprint, or RFID verification) before providing personalized user interfaces and information. The controller determines user identity through authentication first, then selectively provides appropriate user interfaces and information based on the authenticated identity, ensuring that personalization is only granted to authorized users and preventing unauthorized access to personal information.

AI summary
The present disclosure relates to a vehicle control device for a vehicle having a voice input unit, an audio output unit, and a display. The vehicle control device may include a communication unit configured to communicate with at least one of the voice input unit, the audio output unit, and the display, and a processor configured to control the communication unit to output a message for inducing an utterance of a passenger aboard the vehicle in at least one of an auditory manner and a visual manner when a preset event occurs, and identify the passenger based on receiving a response of the passenger to the message through the voice input unit, and perform a different function based on the identified passenger.
