Communication Node Protocol Packing for Diagnosis Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of communication nodes relaying failure diagnosis communication increases, the communication time required for failure diagnosis communication also increases, and using a dedicated bus for failure diagnosis communication leads to an increase in communication channels and buses.
Innovation Solution
A communication system is configured with communication nodes that determine whether current communication is for failure diagnosis and pack a first communication frame of a first communication protocol into a second communication frame of a second communication protocol with higher speed, thereby reducing communication time without using a dedicated bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of communication nodes relaying failure diagnosis communication increases, then the system can perform failure diagnosis communication between more devices, but the communication time required for failure diagnosis communication increases
Solution Approach 1:
The communication system dynamically adjusts the communication protocol based on the type of data being transmitted. For failure diagnosis communication, the system automatically selects a higher-speed protocol (such as Ethernet) instead of using a dedicated slow bus, thereby reducing communication time while maintaining system connectivity through multiple nodes
Solution Approach 2:
The system changes the communication parameter (protocol speed) based on the communication type. By detecting that the communication is for failure diagnosis purposes, the system switches to a higher-speed protocol, effectively changing the transmission speed parameter to reduce communication time without sacrificing connectivity
2Loss of time
If a dedicated bus is installed for failure diagnosis communication, then communication time for failure diagnosis is reduced, but communication channels and buses increase
Solution Approach 1:
The communication system uses existing multi-functional communication buses (such as Ethernet buses used for general vehicle communication) to also handle failure diagnosis communication. This eliminates the need for a dedicated dedicated bus, reducing overall system complexity while still providing fast communication speeds for diagnosis purposes
Solution Approach 2:
The system merges failure diagnosis communication with existing vehicle communication infrastructure. By combining both functions into a single communication bus system, the patent reduces the total number of communication channels while maintaining fast communication speeds through protocol optimization

AI summary
A communication system comprises a plurality of communication nodes that relay failure diagnosis communication of a diagnosis request and a diagnosis result between a request source of a failure diagnosis and a request destination of the failure diagnosis. At least one of the communication nodes is configured to determine whether current communication is the failure diagnosis communication, and to pack a first communication frame of a first communication protocol whose use is defined in a communication standard of the failure diagnosis into a second communication frame of a second communication protocol having a higher communication speed than the first communication protocol.
