Overview (resum en anglès):
The work presented focuses on research on the implementation of Ethernet networks in a vehicle, with the aim of overcoming the limitations of the protocols that have been used in recent years in terms of data transmission capacity. With the constant growth in the incorporation of multimedia devices and advanced driver assistance systems, such as cameras and GNSS systems, Ethernet appears as a viable alternative to improve connectivity and manage larger volumes of information within vehicles. In addition, the project aims to develop tools for the analysis of CAN frames encapsulated in Ethernet frames, using open source software to reduce costs and increase flexibility in its implementation.

The methodology used has consisted of an exhaustive analysis of the most relevant tools and communication protocols in the automotive sector, such as Vector CANoe, Pcan Explorer and Vehicle Spy. In terms of protocols, CAN, CAN-FD and FlexRay, among others, are investigated. In parallel, the development of customized tools using Python has been carried out, as well as the modification of the Wireshark dissectors, in order to facilitate the analysis and visualization of vehicle data. These tools include a generator of DBC files form xlsx files, used to interpret CAN, CAN-FD, LIN and Ethernet messages, another script to decapsulate CAN frames contained in Ethernet frames and a tool to verify the reliability of the captures, which has allowed this type of information to be captured and analysed in Wireshark.

The results obtained help to understand the implementation of Ethernet in a vehicle, showing the usefulness of the tools developed. They allow a deeper and more detailed analysis of vehicular traffic, favoring the integration of open and collaborative solutions in the automotive field. With this, a solid base is established to continue researching the optimization of vehicular networks and the evolution towards more advanced and efficient architectures.
