Dual-Line Wireless Communication Control for Vehicle Data Links
Solution Overview
Problem
Existing wireless communication systems in vehicles face issues with unreliable connections and high communication costs due to limited coverage of wireless LAN access points and unpredictable interruptions, leading to inefficiencies and increased data loss.
Innovation Solution
A wireless communication control device and method that utilizes a dual-line communication approach, using a first line for data transmission (e.g., Wi-Fi) and a second line for communication status sharing (e.g., cellular communication) to maintain connection stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless LAN access point connection is used for vehicle communication, then communication cost is reduced, but connection reliability deteriorates due to limited coverage and high vehicle speed
Solution Approach 1:
The communication system is segmented into two independent lines: the first line (Wireless LAN) is dedicated to data transmission to reduce costs, while the second line (cellular communication) is dedicated to communication status sharing to ensure reliability. This segmentation allows each line to perform its specialized function optimally without interference.
Solution Approach 2:
The second line acts as an intermediary for communication status sharing between the transmission source and destination. By using cellular communication as a mediator to exchange status information independently from the data transmission path, the system maintains connection reliability even when the primary data transmission line experiences interruptions.
2Device complexity
If single line communication is used, then device complexity is reduced, but communication efficiency deteriorates due to inability to maintain status sharing during interruptions
Solution Approach 1:
The communication functions are segmented into data transmission (first line) and status sharing (second line), allowing the system to maintain efficient operations by dedicating each line to its specific purpose.
Solution Approach 2:
The dual-line configuration provides multi-functionality where the system can simultaneously perform data transmission and communication status sharing through different lines, enhancing overall communication efficiency and reliability.
3Speed
If data transmission continues on unstable connection, then data transfer speed is maintained, but data loss increases due to unpredictable interruptions
Solution Approach 1:
The system implements feedback mechanisms through the second line that continuously monitor and share communication status between transmission source and destination. This feedback allows the system to detect interruptions and manage data transmission accordingly, reducing data loss while maintaining efficient transfer speeds through the first line.
Solution Approach 2:
The second line performs preliminary actions by establishing and maintaining communication status sharing independently before data transmission interruptions occur. This preliminary status management enables the system to prepare for and respond to interruptions more effectively, minimizing data loss.
Data Source
AI summary
A control unit is for controlling a wireless communication device usable in a mobile body. The wireless communication device is configured to use first line and second line which are different for a connection to a wireless network, and to transmit and receive data to and from the wireless network via wireless communication. The wireless communication device includes: a data communication processor for performing data communication, which is transmission of data on the first line; and a communication controller for performing communication control for sharing a communication status indicating a progress of data transmission between a transmission source and a transmission destination.
