Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle infotainment systems automatically connect to the most recently connected terminal, which may not be the terminal that needs connection at the current time, leading to inconvenience for drivers.
Innovation Solution
A communication connection method that detects wireless signals from terminals in a vehicle, determines their position relative to the vehicle-mounted device using angle and distance information, and establishes a connection only to the driver terminal, ensuring the vehicle-mounted device connects to the terminal that needs it most.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle-mounted device automatically connects to the most recently connected terminal, then the connection establishment is simple and fast, but the connected terminal may not be the driver terminal that needs connection at the current time
Solution Approach 1:
The system performs preliminary actions by detecting wireless signals and determining terminal positions before establishing connections. The vehicle-mounted device proactively identifies the driver terminal based on position information (angle and distance) rather than waiting for manual selection or relying on connection history, ensuring the correct terminal is connected from the start
Solution Approach 2:
The patent replaces manual terminal selection (mechanical/user-driven system) with automatic position-based identification (sensor-driven system). By using wireless signal detection and position calculation algorithms, the system automatically determines which terminal is at the driver position, substituting human judgment with automated spatial awareness
2Measurement precision
If the vehicle-mounted device uses position-based terminal identification, then the connection accuracy is improved, but the system complexity increases due to signal detection and position calculation
Solution Approach 1:
The wireless signal detection system serves multiple functions: it not only determines terminal position for connection purposes but also provides spatial awareness of all terminals in the vehicle. The same detection mechanism supports both connection establishment and potential future features like terminal location tracking or presence detection
Solution Approach 2:
The system uses the terminals' own transmitted wireless signals (which they emit for other purposes like communication or identification) to determine their positions. The terminals serve themselves by providing the very signals needed for the vehicle-mounted device to identify and connect to the correct terminal without requiring additional dedicated positioning hardware

AI summary
Embodiments of this application provide a communication connection method, an apparatus, and a storage medium. A wireless signal sent by at least one terminal in a vehicle is detected. Position information of the at least one terminal relative to a vehicle-mounted device is determined based on the wireless signal sent by the at least one terminal. In addition, a driver terminal in the at least one terminal is determined based on the position information of the at least one terminal relative to the vehicle-mounted device, and a communication connection is established to the driver terminal. Compared with the conventional technology in which the vehicle-mounted device is preferentially automatically connected to a terminal that is most recently connected to the vehicle-mounted device, this method can avoid a problem that the vehicle-mounted device is still connected to the terminal that is most recently connected to the vehicle-mounted device when the terminal is not a current driver terminal. In other words, the vehicle-mounted device is connected only to the driver terminal each time. To be specific, the vehicle-mounted device is connected only to a terminal that most needs to be connected to the vehicle-mounted device each time. This reduces a connection operation of a driver, and improves convenience of connecting the driver terminal to the vehicle-mounted device.
