Off-Road Vehicle Network Translation Device for Diagnostic Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicle networks lack standardization for diagnostic communication, leading to inefficiencies in data transmission and compatibility issues with on-road vehicle diagnostic tools, as each manufacturer uses proprietary systems, making remote diagnostics and data interpretation challenging and costly.
Innovation Solution
An off-road vehicle network translation device that converts manufacturer-specific messages into ISO 15031 standard messages, enabling transmission via Bluetooth, Wi-Fi, or wired connections, allowing compatibility with on-road vehicle diagnostic tools and interpreting messages in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturer-specific proprietary communication systems are used for off-road vehicle networks, then each manufacturer can optimize their own system performance, but compatibility with standard diagnostic tools and lack of standardized communication protocols results in increased device complexity and reduced adaptability
Solution Approach 1:
The patent introduces a translation device as an intermediary component that sits between the off-road vehicle's proprietary communication network and standard diagnostic tools. This translation device receives messages from the vehicle's control units via the proprietary network, translates them into standardized ISO 15031-4 format messages, and forwards them to diagnostic tools. This mediator approach maintains the reliability of the original manufacturer-specific system while enabling compatibility with standard diagnostic equipment, resolving the contradiction between system optimization and adaptability.
2Loss of information
If entire configuration files are transmitted from central processing center to vehicle electronics for remote diagnostics, then comprehensive diagnostic data can be obtained, but communication channel efficiency is reduced and data transmission time increases
Solution Approach 1:
The translation device extracts and translates only the specific diagnostic information needed from the vehicle's control units rather than transmitting entire configuration files. It selectively retrieves relevant diagnostic data such as error codes, system status, and sensor readings, converting them to standardized format for transmission. This extraction approach maintains complete diagnostic capability while significantly reducing the volume of data transmitted, thereby decreasing communication time and improving channel efficiency.
3Adaptability or versatility
If distinct software payloads are used to accommodate both local and remote connection requirements, then both connection types can be supported, but processing capability is overloaded due to duplicate software
Solution Approach 1:
The translation device serves as an external intermediary that handles the complexity of multiple communication protocols and connection types. Instead of requiring the vehicle's electronics to run duplicate software payloads for different connection methods, the translation device externally manages protocol translation between proprietary and standardized formats. This externalizes the software complexity, allowing the vehicle's processing systems to remain lightweight while still supporting both local and remote diagnostic connections through the same hardware interface.
