V2V Communication Terminal Position-Based Target Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-vehicle communication systems, there is a need to efficiently identify communication targets, especially in scenarios where broadcast communication is used to optimize resource usage, but existing methods lack effective target identification mechanisms.
Innovation Solution
A control method and system that utilize a transmission-side terminal to acquire and transmit identification information specifying a position range, allowing a reception-side terminal to determine if it is within that range, thereby controlling communication accordingly using cameras and sensors for position acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If broadcast communication is used to share channels efficiently, then communication resource usage is optimized, but the ability to identify specific communication targets becomes difficult
Solution Approach 1:
The patent segments the broad broadcast communication into targeted segments by dividing the communication area into multiple regions and assigning different identification information to each region. This allows the system to maintain efficient channel sharing while enabling precise identification of communication targets within specific geographic segments.
Solution Approach 2:
The patent applies local quality by making identification information location-dependent. Each communication area region has its own specific identification information, allowing the system to optimize for both broad resource sharing and local target identification needs. The reception terminal can determine whether to respond based on its current location matching the identification information.
2Measurement precision
If direct specification of communication targets is implemented, then target identification accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent implements self-service by enabling the reception terminal to automatically determine whether it is a communication target based on its current position and the identification information in received signals. The terminal autonomously compares its location with the specified communication area and decides whether to respond, eliminating the need for manual target specification by the user.
Solution Approach 2:
The patent introduces identification information as an intermediary that bridges the gap between broadcast communication and target identification. This intermediary element carries location-based information that allows automatic determination of communication targets without requiring direct user specification or complex manual operations.
3Area of stationary object
If communication area is expanded to cover more regions, then communication coverage is improved, but the precision of identifying specific targets within the area deteriorates
Solution Approach 1:
The patent segments the large communication area into multiple smaller regions, each with its own identification information. This segmentation allows the system to maintain broad overall coverage while enabling precise target identification within each sub-region. The reception terminal can determine its specific location and match it with the appropriate regional identification information.
Solution Approach 2:
The patent adds a spatial dimension to target identification by using geographic location as an additional criterion beyond just communication signal reception. This dimensional approach allows the system to maintain large coverage areas while achieving precise target identification through location-based discrimination.

AI summary
The transmission-side terminal acquires a position of the reception-side terminal, using at least one of a camera and a sensor; and transmits identification information in which an identification range including the position of the reception-side terminal is specified. The reception-side terminal acquires the position of the reception-side terminal; determines whether the position of the reception-side terminal is included in the identification range specified in the identification information transmitted; and performs control to continue communication with the transmission-side terminal, if it is determined that the position of the reception-side terminal is included in the identification range, and performs control to end communication with the transmission-side terminal, if it is determined that the position of the reception-side terminal is not included in the identification range.
