Abstract

As the complexity of automotive Electronic Control Units (ECU) constantly increases with functionalities such as Autonomous Driving (AD), Advanced Driving Assistance Systems (ADAS), and Augmented Reality (AR), new trends emerge in automotive ECU network topologies and software engineering. Centralized ECU architectures are gaining traction, consolidating more vehicle functions into fewer ECUs to reduce network load and improve efficiency, in comparison to traditional de-centralized ECU architectures. However, this shift introduces new challenges, particularly in terms of security and the continual operation of critical functions. A major challenge is that a potential security breach and the subsequent ECU compromise would impact numerous vehicle functionalities. Therefore, ensuring the reliability and security of these systems requires innovative solutions. This paper proposes an approach that addresses these challenges by presenting the concept of “vehicle functions migration” to alternative or auxiliary ECUs, enhancing the overall system’s robustness and security. Finally, the implementation and demonstration of this approach within the EU funded project “REWIRE” is presented.
