Dual-Radio Vehicle Communication for Bidirectional Link Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to quickly and efficiently determine a PCP that optimizes the range for successful inter-vehicle or roadside-to-vehicle communication, especially in dynamic environments like intersections or congested lanes where traffic conditions change frequently.
Innovation Solution
A radio communication apparatus and method that utilize two radio devices: a first device scans for a connection destination on one side of a moving object (front or back), and a second device transmits signals to detect a connection destination on the opposite side, enhancing the success rate of radio connections in moving object-to-moving object or roadside apparatus-to-moving object communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single radio device is used to scan for connection destinations, then the device complexity is reduced, but the reliability of radio connection decreases in dynamic environments
Solution Approach 1:
The radio communication apparatus is divided into multiple radio devices (first radio device and second radio device), each responsible for scanning in different directions. This segmentation allows simultaneous multi-directional scanning, improving connection success rate while distributing the complexity across multiple specialized components rather than one complex device
2Adaptability or versatility
If radio devices scan only in one direction, then the device complexity is reduced, but the adaptability to dynamic traffic conditions deteriorates
Solution Approach 1:
The scanning mechanism transitions from single-directional to multi-directional by adding spatial dimension. The first radio device scans in one direction while the second radio device scans in another direction, creating comprehensive angular coverage without requiring a single device to perform complex omnidirectional scanning
3Reliability
If multiple radio devices are deployed to scan different directions, then the reliability of communication is improved, but the loss of time for signal detection increases
Solution Approach 1:
Multiple radio devices perform scanning operations simultaneously and continuously in different directions rather than sequentially. This parallel continuous scanning ensures that connection detection occurs without interruption across all directions, maintaining reliability while minimizing detection time through concurrent operations

AI summary
The present invention improves the success rate of wireless connection in communications between moving objects or roadside unit-to-moving object communications. A wireless communication device (100) includes a first radio (101) and a second radio (102). The first radio (101) scans, at one of the front and rear of a moving object (10), a first connection destination detecting signal for first moving object-to-moving object communication or first roadside unit-to-moving object communication. The second radio (102) transmits, toward the other of the front and rear of the moving object (10), a second connection destination detecting signal for second moving object-to-moving object communication or second roadside unit-to-moving object communication.
