The project framework involves a Gateway Simulator acting as the central node, interfacing with both the DoCan Tester and the DoIP Tester via CAN and Ethernet connections, respectively. The ECU nodes are connected through the CAN interfaces, emphasizing the Gateway Simulator's role in routing and managing communications within the automotive body network. Given the complexity and scale of communication between actual vehicle nodes, this project will focus on the routing function of diagnostic communication. This means we will concentrate our efforts on developing and optimizing the data transmission paths related to vehicle diagnostics, ensuring efficient and reliable transfer of diagnostic information between different Electronic Control Units (ECUs). Through this approach, we aim to simplify the complex communication network and enhance the efficiency and accuracy of the diagnostic process. Please refer to the simple pic of architecture for better understanding.

The reason choose rt-thread
-
I strongly agree with the concept of the RTThread project. The abstract and modular features will bring about a very good software architecture.
-
Since graduated, I have been working in automotive electronics and have not had any exposure to rtos other than AutosarOS. This is also a great opportunity to broaden my horizons
-
RTThread is a very friendly project. The community is very active and friendly. I can get help from the community very quickly.
