EEA4CCAM proposes in-vehicle electronic control architectures for Connected, Cooperative, and Automated Mobility (CCAM) applications, ensuring safe and cyber-secure deployment across diverse operating conditions. By integrating hardware and software co-design, EEA4CCAM enables smart data flows and secure operation through a centralized, upgradable architecture. The project aims to empower the safe and cyber-secure deployment of CCAM solutions through a novel, centralized, and upgradable in-vehicle electronic control architecture. This will be achieved by performing a paradigm shift in in-vehicle electronic control architectures, developing a centralized, upgradable, and open-source design that integrates HW and SW co-design, enables smart data flows, and ensures safe and cyber-secure operation. The project will foster international cooperation, harmonization, and standardization, promoting open-source interfaces and layouts, and facilitating the development and integration of CCAM applications through exemplarily deployment and validation methods. Five key objectives will be achieved: developing a new, centralized design; exemplarily deploying level 4 automation use cases; enabling safe and cyber-secure operation through system agility and distributed intelligence; realizing a paradigm shift to integrated, resource-efficient architectures; and setting up international cooperation for harmonized electronic control architecture layouts, promoting open-source interfaces and layouts. By achieving these objectives, EEA4CCAM will lay the foundation for the software-defined-vehicle, enabling the widespread adoption of CCAM applications and paving the way for a safer, more efficient, and more connected transportation system.
