V2X Vehicle Communication Device for Non-V2X Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where vehicles capable of performing V2X communication interact with those incapable of doing so, the latter are often unrecognized, posing a risk due to lack of information, which hampers autonomous driving systems.
Innovation Solution
A communication apparatus that transmits and receives recognition information for vehicles unable to perform V2X communication, enabling vehicles capable of V2X to share and display necessary information like presence, location, and speed, allowing for safer navigation.

Engineering Contradiction Analysis
1Reliability
If V2X communication is implemented to share information between vehicles, then safety and awareness of surrounding vehicles is improved, but vehicles incapable of performing V2X communication cannot be detected or recognized
Solution Approach 1:
The patent introduces an intermediary mechanism where V2X-capable vehicles act as mediators to transmit information about non-V2X vehicles. When a V2X-capable vehicle detects a non-V2X vehicle through its sensors, it generates and transmits a message containing the non-V2X vehicle's information (position, speed, direction) to other V2X-capable vehicles, enabling indirect awareness of vehicles that cannot communicate directly.
Solution Approach 2:
The patent creates a virtual copy or representation of the non-V2X vehicle's information through structured messages. The detected physical characteristics and state of the non-V2X vehicle are converted into a standardized data format that can be transmitted and processed by the V2X network, allowing other vehicles to perceive and respond to the non-V2X vehicle as if it were part of the communication network.
2Loss of information
If proxy messages are transmitted for non-equipped vehicles, then information sharing is improved, but communication efficiency deteriorates when multiple vehicles transmit redundant proxy messages
Solution Approach 1:
The patent implements a feedback mechanism where V2X-capable vehicles monitor and track the transmission status of proxy messages. When a vehicle transmits a proxy message for a non-V2X vehicle, other vehicles that receive and process this information can provide feedback to avoid redundant transmissions, thereby maintaining information sharing while improving communication efficiency.
Solution Approach 2:
The patent allows for selective transmission of proxy messages based on situational necessity. Rather than requiring every V2X-capable vehicle to continuously transmit proxy messages for all non-V2X vehicles, the system transmits information partially or excessively only when needed for safety or when the non-V2X vehicle enters a relevant detection zone, optimizing communication resource usage.

AI summary
Disclosed is a communication apparatus for a vehicle, including: an interface unit configured to receive sensing information regarding a first other vehicle located in a vicinity of the vehicle and incapable of performing vehicle-to-vehicle communication; a transmitter configured to transmit information to a second other vehicle capable of performing vehicle-to-vehicle communication; and a processor configured to generate recognition information for the first other vehicle based on the sensing information, and transmit the recognition information for the first other vehicle to the second other vehicle through the transmitter.
