Abstract: The intelligent vehicle cyber-physical system (IVCPS) is a system-of-systems with evolving and emergent properties, demanding robust architectural design. To develop a feasible, verifiable, and scalable IVCPS architecture, the Scenario-oriented Model-and-Simulation-based System-of-Systems Engineering approach is proposed. This method examines IVCPS’s structure and evolution, adopting the Unified Architecture Framework Modeling Language to build a distributed framework maintaining consistent models across scenario task systems. The architecture is developed from seven viewpoints and validated via simulations. A standard model library is established to enable quick adaptation to new scenarios, while integrated multi-resolution simulations ensure positive system emergence. The system layer adopts MBSE for modeling and simulation. A case study of the demonstrates the first-stage IVCPS architecture. Simulations validate its logic and parameters, confirming the capacity to address system development needs, facilitate design transitions, identify hidden collaborative requirements, and quickly assemble new scenario architectures.
