Vehicle Communication Relay via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In accident or dangerous situations, vehicle communication is hindered due to the lack of communication technology in all vehicles, making it difficult for vehicles to warn each other effectively.
Innovation Solution
A method where a first vehicle transmits data to a server using a specific communication protocol, allowing the server to relay this information to a second vehicle, which then forwards it to a third vehicle using a different protocol, enabling communication without the first vehicle needing direct communication capabilities with the third vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a first vehicle transmits data directly to other vehicles using vehicle-to-vehicle communication technology, then communication between vehicles is achieved, but this requires all vehicles to have communication technology which is not the case in reality
Solution Approach 1:
The patent introduces a server as an intermediary between vehicles. The first vehicle transmits data to the server, which then relays the information to a second vehicle that has communication capabilities, enabling the second vehicle to forward warnings to the third vehicle. This mediator approach allows communication between vehicles regardless of their individual communication technology status.
2Reliability
If the server transmits data to multiple vehicles individually, then all vehicles can receive information, but this increases the server's communication burden and complexity
Solution Approach 1:
The patent makes the second vehicle serve multiple functions: it receives data from the server and simultaneously acts as a relay to transmit warnings to the third vehicle. This multi-functionality reduces the server's burden as it only needs to communicate with the second vehicle, which then handles distribution to other vehicles.
3Adaptability or versatility
If all vehicles are equipped with communication technology to enable direct vehicle-to-vehicle communication, then communication capability is improved, but this increases device complexity and cost
Solution Approach 1:
The patent segments the communication function across different vehicles and a server. Not all vehicles need full communication technology - only those that will be relaying messages (like the second vehicle). The server handles communication with vehicles that lack capabilities, dividing the communication burden and reducing requirements for individual vehicles.

AI summary
The invention relates to a method for vehicle communication, in which a first vehicle provides first data (DATA_1) for communication with a server. The first data (DATA_1) is transmitted to a server by radio technology using a first communication protocol. The server transmits second data (DATA_2) to a second vehicle by radio technology using the first communication protocol, said second data (DATA_2) being determined depending on the first data (DATA_1). Depending on the second data (DATA_2), third data (DATA_3) is transmitted by the second vehicle to a third vehicle by radio technology using a second communication protocol.
