Vehicle Access System Using Face and Gesture Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle access methods, such as smart keys and digital keys, may fail to allow entry if the user does not have the key, and face authentication can be unreliable, especially under varying conditions like changes in appearance or lighting, potentially leading to unauthorized access or locked vehicles.
Innovation Solution
A vehicle system equipped with a camera for face and gesture image acquisition, a communication module for mobile device interaction, and a processor for performing user authentication, which allows unlocking via emergency access signals, driver identification, or arbitrary authentication numbers and gestures when face authentication fails, ensuring secure and convenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face authentication is used for vehicle access, then user convenience is improved (access without key), but reliability deteriorates (authentication failures due to appearance changes or lighting conditions)
Solution Approach 1:
The system pre-registers multiple authentication methods (face images, gestures, emergency access codes) and communication protocols with the mobile device before authentication failures occur. When face authentication fails, the system has already prepared alternative verification channels through which the user can access the vehicle, eliminating the need for re-registration or system reconfiguration during emergency situations.
Solution Approach 2:
The mobile device serves as an intermediary between the user and the vehicle authentication system. When face authentication fails, the system communicates with the user's mobile device to verify identity through alternative methods (emergency access signals, pre-registered gestures), allowing authentication to proceed through a mediating channel rather than direct face recognition alone.
2Reliability
If multiple authentication methods are provided, then reliability is improved (backup access methods), but device complexity increases (multiple cameras, communication modules, processors)
Solution Approach 1:
The camera system performs multiple functions: capturing face images for primary authentication, detecting gestures for alternative authentication, and monitoring for emergency access procedures. The communication module handles multiple protocols and communication scenarios (normal operation, authentication failures, emergency access). This multi-functionality reduces the need for separate dedicated components for each authentication method, thereby managing complexity while maintaining reliability.
Solution Approach 2:
The system combines face recognition, gesture recognition, and mobile device communication into a unified authentication framework controlled by a single processor. Rather than implementing separate independent systems for each authentication method, the patent merges these functions into an integrated system where components work together, sharing hardware resources and processing capabilities, thus reducing overall system complexity.

AI summary
A vehicle may include a camera configured to acquire a face image of a user approaching from outside the vehicle and a gesture image of the user; a communication module configured for communicating with a mobile device; a door locking device configured to lock a door of the vehicle or unlock the door of the vehicle; and a processor configured to perform user authentication based on the user's surface image, and unlock the door when the user authentication is successful, and the processor may be configured to control the communication module to transmit the user's face image to a pre-registered mobile device when the user authentication fails a preset number of times, control the communication module to receive an emergency access signal from the pre-registered mobile device, and control the door locking device to unlock the door when a user's gesture image satisfies an unlock condition.
