Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting terminal devices like mobile phones to vehicle systems, such as USB wired connections, WiFi hotspot wireless connections, and WiFi direct connections, are either complex, unstable, or require manual user intervention, leading to poor performance and high power consumption.
Innovation Solution
A method that automatically establishes a WiFi direct connection between a mobile terminal and a car machine apparatus using a Bluetooth communication connection to negotiate and determine parameter information, allowing the terminal device to initiate a WiFi direct connection request without manual user selection, thereby reducing user operations and ensuring a stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If USB wired connection is used, then connection stability is improved, but operation complexity increases
Solution Approach 1:
The patent uses Bluetooth as an intermediary communication channel to establish WiFi direct connections. The Bluetooth connection serves as a mediator that enables automatic parameter negotiation and connection establishment between terminal devices and vehicle systems, eliminating the need for manual USB cable connections while maintaining connection stability.
2Ease of operation
If WiFi hotspot connection is used, then ease of operation is improved, but power consumption increases
Solution Approach 1:
The patent extracts the hotspot function from the terminal device and implements it within the vehicle system instead. By using WiFi direct connection established through Bluetooth negotiation, the terminal device does not need to activate its hotspot, thereby significantly reducing power consumption while maintaining ease of operation.
3Reliability
If WiFi direct connection is used, then connection stability is improved, but automation level decreases
Solution Approach 1:
The patent implements preliminary action by using Bluetooth to pre-negotiate all necessary connection parameters (SSID, authentication type, encryption keys) before establishing the WiFi direct connection. This preliminary parameter exchange through Bluetooth enables the WiFi connection to be automatically established without requiring user intervention, thereby increasing automation level while maintaining connection stability.
4Measurement precision
If manual device selection is required, then connection accuracy is improved, but time consumption increases
Solution Approach 1:
The patent implements feedback mechanism where the vehicle system actively sends its identification information and connection parameters to the terminal device through Bluetooth. The terminal device receives this feedback information and automatically matches it with available WiFi networks, eliminating the need for manual device selection while ensuring accurate connection to the correct vehicle system.

AI summary
The present application discloses a wireless connection establishment method, an apparatus, a device and a storage media, which is applied to artificial intelligence, Internet of Vehicles and intelligent transportation technologies in the field of computer technology. A specific implementation scheme is as follows: by before establishing a WiFi direct connection between a car machine apparatus and a terminal device, a Bluetooth communication connection between the two is established firstly, the car machine apparatus provides parameter information required to establish the WiFi direct connection with the car machine apparatus to the terminal device through the Bluetooth communication connection, then the terminal device can automatically send a WiFi direct connection request to the car machine apparatus based on the parameter information, and the car machine apparatus device establishes the WiFi direct connection with the terminal device in response to the WiFi direct connection request initiated by the terminal device without a manual search as well as a selection and confirmation of the WiFi device to be connected by the user, an automatic establishment of the WiFi direct connection between the car machine apparatus and the terminal device is realized, user operations are reduced, and would not affect other functions such as driving the vehicle or using the terminal device by the user.
