Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems face inefficiencies in network resource utilization and increased risk of communication failure or delay due to the growing number of electronic control modules and data traffic in vehicle networks.
Innovation Solution
Implementing an edge communication node that receives and protocol converts or routes diagnostic messages, reducing external channel connections and optimizing transmission frequency based on diagnostic results to enhance network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic control modules and data traffic in vehicle networks increases to support advanced vehicle technology, then diagnostic capability and monitoring coverage are improved, but network resource utilization efficiency deteriorates and communication failure or delay risk increases
Solution Approach 1:
The patent segments the vehicle network into multiple communication domains (e.g., powertrain domain, chassis domain, body domain) with domain controllers managing each segment. This segmentation reduces the complexity of the overall network, improves resource utilization efficiency within each domain, and enhances communication reliability by isolating potential failures to specific segments rather than affecting the entire network.
2Measurement precision
If diagnostic messages are transmitted frequently to ensure comprehensive diagnostic coverage, then diagnostic precision is improved, but network resource consumption increases and communication delay risk increases
Solution Approach 1:
The patent implements periodic action by transmitting diagnostic messages at optimized intervals rather than continuously. The system determines appropriate transmission timing based on diagnostic requirements and network conditions, achieving comprehensive diagnostic coverage while reducing unnecessary message transmissions that consume network resources and increase communication delay risk.
Solution Approach 2:
The patent employs feedback mechanisms where the diagnostic system monitors network resource utilization and communication conditions, then adjusts diagnostic message transmission frequency accordingly. When network resources are abundant and diagnostic accuracy requirements are met, transmission frequency is reduced to conserve resources. When diagnostic precision needs improvement or resources are available, transmission frequency increases, thus optimizing the balance between diagnostic precision and network resource consumption.
