On-Vehicle Bluetooth Connection via Driver Face Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hands-free communication systems in vehicles using Bluetooth technology lack secure and efficient methods to ensure that only the driver's device connects, potentially leading to inconvenience and safety risks due to unauthorized device connections during driving.
Innovation Solution
A method and apparatus that utilize face recognition to identify the driver and establish a Bluetooth connection based on a unique face identifier, ensuring that only the driver's device connects to the vehicle's Bluetooth system, thereby enhancing user experience, driving efficiency, and Bluetooth connection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional Bluetooth connection methods are used in vehicles, then ease of operation is improved (hands-free communication), but reliability deteriorates (unauthorized devices can connect)
Solution Approach 1:
The system performs face recognition and establishes the Bluetooth connection mapping before actual driving occurs. The driver's face is captured during a preset period (e.g., when the vehicle is started but before driving begins), and the corresponding Bluetooth device is pre-bound to this face identifier. This preliminary action ensures that only the authorized driver's device can connect during driving, resolving the security issue while maintaining ease of operation.
2Reliability
If face recognition technology is added to Bluetooth connection system, then connection security is improved, but device complexity increases
Solution Approach 1:
The vehicle's existing camera system, originally designed for other purposes (e.g., monitoring, assistance), is repurposed to perform face recognition for Bluetooth connection authorization. By making the camera multi-functional, the system adds security capabilities without requiring separate dedicated hardware, thus minimizing the increase in device complexity while achieving reliable connection security.
3Measurement precision
If face recognition is performed during driving, then connection accuracy is improved, but loss of time increases (affecting driving efficiency)
Solution Approach 1:
The system performs face recognition and Bluetooth device binding during a preset period before driving begins (e.g., when the vehicle is started but the driver has not yet begun driving). This preliminary establishment of the face-Bluetooth mapping ensures that during actual driving, no additional face recognition processing is needed, thereby maintaining high identification accuracy while avoiding any loss of driving time.

AI summary
A method and an apparatus for connecting through on-vehicle Bluetooth, and a storage medium includes: acquiring a first face image of a driver in response to an on-vehicle Bluetooth apparatus being on; determining a first face identifier corresponding to the driver by performing face recognition on the first face image; querying a first correspondence according to the first face identifier, in which the first correspondence indicates a correspondence between face identifiers and Bluetooth identifiers of terminals; in response to determining a first Bluetooth identifier matching the first face identifier, establishing, according to the first Bluetooth identifier, a Bluetooth connection between the on-vehicle Bluetooth apparatus and a first terminal Bluetooth apparatus corresponding to the first Bluetooth identifier.
