ROS–AUTOSAR Communication via Data Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data collection and driving status visualization tool software developed on one platform, such as ROS, cannot be used together with intelligent driving software developed on another platform like AUTOSAR Adaptive Platform, leading to development complexity and high maintenance costs due to the need for high-risk open-source software integration.
Innovation Solution
A communication method and apparatus that enables cross-communication middleware and cross-device communication by converting data formats and using a data packet header to facilitate communication between devices using different platforms, such as AUTOSAR and ROS, without requiring high-risk open-source software installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tool software is developed based on ROS platform, then the software can be easily developed and used, but the software cannot be used with AUTOSAR Adaptive Platform due to different communication middleware
Solution Approach 1:
The patent introduces a data conversion module as an intermediary component that translates data formats between ROS and AUTOSAR protocols. This converter acts as a mediator layer, allowing tool software developed on ROS to communicate with AUTOSAR platforms without requiring the software to be rewritten for the target platform, thus resolving the compatibility issue while preserving development ease
Solution Approach 2:
The patent creates a universal communication interface that can handle both ROS and AUTOSAR protocols through a single data conversion module. This multi-functional converter enables the same tool software to operate on different platforms (ROS and AUTOSAR) without modification, achieving cross-platform versatility while maintaining the original development simplicity
2Reliability
If different communication middleware are used for different platforms, then each platform can use its own optimized communication system, but integration between platforms becomes complex and maintenance costs increase
Solution Approach 1:
The patent segments the communication system into distinct protocol handlers (ROS protocol layer and AUTOSAR protocol layer) and a conversion layer. This segmentation allows each platform to maintain its own optimized communication middleware while the conversion layer handles the integration, reducing overall system complexity by isolating platform-specific details
3Adaptability or versatility
If high-risk open-source software is installed to enable cross-platform communication, then compatibility can be achieved, but security risks and maintenance costs increase
Solution Approach 1:
The patent employs a lightweight data conversion module that can be easily implemented and removed without long-term maintenance commitments. This disposable conversion layer provides the necessary cross-platform compatibility through simple protocol translation rather than requiring complex, high-risk open-source software frameworks, thus reducing security risks while maintaining adaptability
Data Source
AI summary
A communication method includes a first device that determines second data based on first data, where the first data and the second data meet a data type mapping relationship, and the data type mapping relationship includes a conversion relationship between data formats of different protocols; the first device generates third data based on the second data, where the third data includes the second data and description information of the second data; and the first device sends a first message to a second device, where the first message includes a data packet header and the third data.
