Solution Overview
Problem
Current vehicle networking technologies face inefficiencies in establishing reliable and energy-efficient wireless direct connections between vehicle-mounted and mobile terminals, often requiring continuous scanning of surrounding devices, which consumes energy and hampers data transmission efficiency.
Innovation Solution
The method employs a short-range wireless communication protocol, specifically NFC, to acquire and transmit device information between mobile and vehicle-mounted terminals, enabling a point-to-point wireless direct connection without the need for continuous scanning, thereby establishing a more efficient and pertinent vehicle-machine interconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous scanning is used to establish wireless connections, then connection reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies preliminary action by having devices exchange connection information through NFC before establishing the actual data transmission channel. The mobile terminal and vehicle terminal perform near-field communication to share device identifiers and connection parameters in advance, so that when the wireless connection is established, both parties already have the necessary information to connect directly without scanning. This resolves the contradiction by preparing connection details beforehand, ensuring reliability while avoiding continuous scanning energy consumption.
2Ease of operation
If Bluetooth or WiFi scanning is used for device discovery, then connection establishment is achieved, but data transmission efficiency is reduced
Solution Approach 1:
The patent uses NFC to perform preliminary information exchange between the mobile terminal and vehicle terminal before establishing the main data transmission channel. During this preliminary phase, device identifiers, connection parameters, and channel information are shared through near-field communication. This allows the subsequent wireless connection to be established immediately without scanning delays, thus maintaining ease of operation while significantly improving data transmission efficiency by eliminating the scanning bottleneck.
Solution Approach 2:
The patent introduces NFC as an intermediary mechanism to facilitate the connection establishment process. Instead of using Bluetooth or WiFi scanning directly for device discovery, the system uses NFC as a mediator to exchange connection information first. This intermediary step enables both terminals to obtain each other's connection details through a different communication path, allowing the main data transmission channel to be established more efficiently without the overhead of continuous scanning.
3Stability of the object's composition
If wired connection is used for interconnection, then connection stability is improved, but user experience and convenience are reduced
Solution Approach 1:
The patent merges the advantages of wired connections with wireless convenience by combining NFC technology with wireless data transmission. The NFC component provides the stable, reliable connection establishment similar to wired connections, while the subsequent wireless channel (WiFi or Bluetooth) provides the convenience of wireless data transmission. This merging allows users to enjoy both connection stability and wireless ease of operation, eliminating the need for physical cables while maintaining connection reliability.

AI summary
The present disclosure provides a method and apparatus for interconnecting a vehicle and a machine, and relates to the field of communication technology, and specifically to the field of vehicle networking technology. A specific implementation comprises: acquiring device information used for a wireless direct connection first; then sending the device information to a vehicle-mounted terminal based on a short-range wireless communication protocol; and finally, receiving a connection request based on the device information, and establishing a wireless direct connection with the vehicle-mounted terminal sending the connection request. A vehicle-machine interconnection is implemented through the data transmission based on the short-range wireless communication protocol, without the need to continuously scan surrounding devices like a Bluetooth module, thereby saving the device energy consumption and improving the pertinence of the vehicle-machine interconnection.
