Exploring Protocol Diversity in In-Vehicle Networks: Simulated Data Revelation

Modern vehicles heavily rely on various Electronic Control Units (ECUs) to ensure proper operation, safety and efficiency. In-Vehicle Network (IVN) facilitates communication and the flow of information between ECUs. Commonly used IVN protocols include Controller Area Network (CAN), Local Interconnect Network (LIN), FlexRay, Ethernet, Media Oriented System Transport (MOST), and CAN with flexible data transfer (CAN-FD). Understanding the effect of these protocols on data generation, transfer, and ECU behaviour is critical to improving communication and enhancing the safety and security features of automotive communication systems. This work focuses on using the Vector CANoe tool to simulate real-world scenarios and analyse the complexities of IVN protocols. The research aims to improve automotive communication systems by examining the performance of these protocols in virtual environments. The findings from this work offer valuable insights for enhancing in-vehicle communications through simulation and testing.
