Vehicle Door Gesture Control With Face Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door control systems fail to securely prevent unauthorized access, as they can be opened by gestures from both registered and non-registered individuals, compromising vehicle security while aiming to enhance user convenience.
Innovation Solution
A vehicle control system that includes a vehicle outside image acquisition unit, first and second detection units for identifying and authenticating registered users based on predetermined motions and facial recognition, and a door control unit that performs door opening control only when the detected motion is from a registered user, ensuring secure and convenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door opening control is enabled based on gesture detection, then user convenience is improved, but vehicle security deteriorates because third parties can also open the door
Solution Approach 1:
The door opening control function is segmented into two independent authentication pathways: gesture-based control for convenience and face recognition authentication for security. The system divides the single door control function into multiple sub-functions that can be independently activated, allowing users to benefit from both convenience and security without compromise.
Solution Approach 2:
The face recognition authentication unit acts as an intermediary between the gesture detection and door opening control. When a third party attempts to use gesture control, the face recognition unit intercepts and validates the user's identity before allowing door opening, thereby preventing unauthorized access while maintaining the convenience of gesture-based operation for registered users.
2Reliability
If face recognition authentication is added to verify registered users, then vehicle security is improved, but device complexity increases
Solution Approach 1:
The image processing unit serves multiple functions: it processes images for both gesture detection and face recognition authentication. By making this component multi-functional, the system avoids adding separate hardware for each function, thereby improving security through face recognition while minimizing the increase in device complexity.
Solution Approach 2:
The face recognition authentication unit is integrated with the existing gesture detection system rather than being implemented as a completely separate subsystem. The control unit merges the logic of gesture-based door control with face recognition verification, creating a unified control system that reduces overall complexity compared to having entirely separate systems.

AI summary
A control system includes: a vehicle outside image acquisition unit configured to acquire a vehicle outside image; a first detection unit configured to detect a vehicle outside person based on the vehicle outside image; a second detection unit configured to detect a predetermined motion of the detected vehicle outside person; a first authentication unit configured to authenticate whether or not the detected vehicle outside person is a registered user of the vehicle based on a predetermined part of the detected vehicle outside person; and a door control unit configured to perform door opening control of the vehicle. The door control unit performs the door opening control in a first mode based on the predetermined motion, when the detected predetermined motion is the predetermined motion of the vehicle outside person authenticated as the registered user.
