Vehicle Device Automatic Mobile Terminal Connection via Cabin Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle hands-free systems struggle to automatically connect to the correct mobile terminal when a new driver enters the vehicle, leading to inconvenience and potential safety issues due to the inability to use hands-free functions.
Innovation Solution
A vehicle device equipped with a camera to capture the inside of the cabin, a passenger detector to identify passengers and their boarding positions, a determiner to assess the connectivity of associated mobile terminals, a decider to select the appropriate mobile terminal based on passenger positions, and a communication controller to establish a near-field communication connection with the selected mobile terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the hands-free device automatically connects to the most recently connected mobile terminal, then the connection is simple and fast, but it cannot adapt when a new driver enters the vehicle
Solution Approach 1:
The system performs preliminary actions by capturing images of passengers before they operate the vehicle, identifying them in advance, and determining their associated mobile terminals. This allows the hands-free device to be pre-configured with the correct connection information before the driver needs to use it, eliminating the need for manual reconfiguration when drivers change.
Solution Approach 2:
The system uses feedback from the camera to detect passenger presence and from the image recognition algorithm to identify passengers. This feedback loop continuously monitors the cabin, detects when a new driver enters, and automatically triggers the connection switching process, enabling the system to adapt dynamically to changes in the driving situation.
2Reliability
If manual selection of mobile terminal is required for each driver, then connection accuracy is high, but operation complexity and time consumption increase
Solution Approach 1:
The system performs self-service by automatically detecting passengers, identifying them through image recognition, determining their mobile terminals, and establishing connections without requiring any manual intervention. The hands-free device serves itself by autonomously managing the connection switching process based on passenger detection and identification results.
3Speed
If driver's seat camera is used for face recognition, then identification speed is fast, but it cannot detect passengers in other seats
Solution Approach 1:
The camera system is designed with multi-functionality to serve multiple purposes: it not only captures images for driver identification but also detects passengers in various seats throughout the cabin. By making the camera universal in its detection capability, the system can identify any passenger regardless of their seating position and manage connections for different users.
Solution Approach 2:
The system transitions from a single-point detection approach (driver's seat only) to a multi-dimensional detection approach by positioning cameras to capture the entire cabin space. This dimensional expansion allows simultaneous monitoring of multiple seating positions, enabling the system to detect and identify passengers anywhere in the vehicle.
4Reliability
If the system waits for driver to notice and manually connect, then connection reliability is high, but convenience and safety are reduced
Solution Approach 1:
The system performs preliminary connection setup by detecting the driver, identifying them, and establishing the connection to their mobile terminal before the driver needs to use the hands-free function. This preliminary action ensures that the connection is already in place and verified, maintaining reliability while eliminating the need for manual operation at the moment of use.

AI summary
A passenger detector identifies biometric information of a passenger on board a vehicle from a video captured by a camera that captures the inside of the cabin of the vehicle and specifies the boarding position of the passenger. A determiner determines whether or not a mobile terminal associated with the biometric information identified by the passenger detector is in a state of being connectable by near field communication. In a case where there is a plurality of mobile terminals determined by the determiner to be in a state of being connectable by near field communication, a decider decides a mobile terminal to be connected by near field communication on the basis of boarding positions of a plurality of passengers specified by a plurality of pieces of biometric information associated with the plurality of mobile terminals. A communication controller connects the mobile terminal decided by the decider and the vehicle device by near field communication.
