The automotive industry is undergoing a significant transformation towards Software Defined Vehicles (SDVs), necessitating a flexible system architecture. Container orchestration emerges as a promising solution for managing software in distributed systems, allowing for the full utilization of service-oriented architectures (SOA). Additionally, PCIe facilitates efficient data transfer across host borders, achieving higher data rates than Ethernet-based systems while simultaneously reducing CPU overhead. Integrating container orchestration within SOA and utilizing PCIe enables portable software solutions without network constraints. This study evaluates the application of containers and PCIe in modern SDV architectures, aiming to enhance flexibility and efficiency in software integration and management.

The Software-Defined Vehicle paradigm is disrupting the automotive domain by introducing DevOps processes in a product-oriented industry. In this context, the European project CODE4EV targets to accelerate vehicle development by establishing a collaborative development framework addressing the entire lifecycle and aiming at improving efficiency, safety, and scalability across vehicle categories. A distinctive feature is its support for distributed testing in an agent based setup to lever geographically dispersed partners and lab infrastructures. Target of this paper is to introduce the framework along the three automotive industrial use cases, and deployed for passenger cars, two-wheelers and heavy-duty trucks.

Legacy Meets Future: SOA Migration and Signal-to-Service Integration for Automotive HPCs

Software-Defined Vehicles (SDVs) drive a shift from hardware-centric systems to flexible, connected platforms powered by Service-Oriented Architecture (SOA). However, Legacy Electronic Control Units (ECUs) with signal-based communication pose challenges in transitioning to SDV-ready E/E architectures. To overcome these challenges, this paper introduces a unified modernization strategy that combines SOA migration workflows with a Signal-to-Service (S2S) translation framework, enabling seamless coexistence between legacy ECUs and next-generation High-Performance Computing (HPC) platforms. For cases where direct migration is not feasible, a scalable S2S gateway translates CAN signals to Ethernet service interfaces, ensuring interoperability across domains while meeting automotive-grade latency, safety, and security requirements.

A Semantics-Preserving Master Scheduler for Mixed-Criticality Control in Lingua Franca

Yutaka Matsubara (Nagoya University)･Wenhung Kevin Huang･Akihito Iwai (DENSO)

We designed and evaluated a scheduler for a container-based consolidated ECU that guarantees deterministic process execution order in a mixed environment of Lingua Franca–compliant real-time applications and non-LF applications.

Software Updates as Enabler for Cyber Security in the CV Domain
-From Regulations to Processes to a One-Stop System Solution-

Alexander Roy･Gila-Marie Achenbach (IAV)･Dennis Kengo Oka (IAV Japan)

Increasing digitalization in commercial vehicles makes cybersecurity and software updates critical. Secure update mechanisms are essential for compliance as regulations tighten. While major OEMs have implemented Software Update Management Systems (SUMS), smaller companies face challenges as exemptions end. Regulations require automated, traceable processes beyond manual updates. SUMS offers a holistic approach, including version control, approval workflows, and risk assessment. IAV's modular, cloud-based SUMS enables OEMs and suppliers to deliver secure, scalable updates and integrate seamlessly into existing environments—reducing complexity and accelerating deployment.
