Vehicle Wireless Linkage Control Using GPS Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular AVNT systems fail to reliably release wireless communication linkage with mobile terminals when they are outside the vehicle, leading to inconvenience and errors in maintaining or releasing connections.
Innovation Solution
A wireless communication linkage control apparatus that uses a communicator, position signal receiver, and controller to determine the position of a mobile terminal based on GPS information and vehicle state information, releasing the linkage when the terminal is outside the vehicle, employing methods like high-frequency sound, trilateration, and fingerprinting technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication linkage is maintained automatically when mobile terminal enters vehicle, then convenience for user is improved, but wireless communication linkage error occurs when terminal is outside vehicle
Solution Approach 1:
The system continuously monitors the position of the mobile terminal using GPS information and compares it with the vehicle's position. This feedback mechanism allows the system to detect when the terminal moves outside the vehicle and automatically release the wireless linkage, resolving the contradiction between maintaining convenient automatic connection and preventing erroneous connections when the terminal is outside the vehicle.
2Reliability
If wireless communication linkage is released when mobile terminal moves outside vehicle, then wireless communication linkage error is reduced, but inconvenience occurs when terminal should remain connected
Solution Approach 1:
The system pre-establishes connection criteria based on vehicle state information (engine on/off, door open/closed) before determining whether to release the wireless linkage. This preliminary assessment of vehicle context allows the system to make intelligent decisions about connection release, ensuring that connections are only released when the terminal is truly outside the vehicle and not when temporary disconnections are acceptable.
3Measurement precision
If position determination method is determined based on vehicle state information, then position determination accuracy is improved, but device complexity increases
Solution Approach 1:
The system dynamically changes the position determination method based on vehicle state parameters (engine status, door status, GPS availability). When GPS is available and vehicle is moving, it uses GPS-based positioning; when vehicle is stationary or GPS is unavailable, it uses other methods like Wi-Fi positioning or cellular tower triangulation. This parameter-based adaptation improves position determination accuracy without requiring a single complex positioning system.

AI summary
An embodiment wireless communication linkage control apparatus is configured to determine a position determination technique of a mobile terminal based on state information of a vehicle, to determine the current position of the mobile terminal, thereby controlling maintenance or release of wireless communication linkage with the mobile terminal depending on the position of the mobile terminal.
