Abstract
The automotive landscape is experiencing a paradigm shift, driven by the pervasive integration of artificial intelligence (AI) across all functional layers, the availability of previously unattainable data-processing capabilities, and an increasingly tight convergence of sensors, actuators, and advanced communication technologies. This perspective article explores the evolution from connected vehicles to Software (SW)-defined vehicles (SDVs), focusing on the emerging frontier of AI-defined vehicles (AIDVs) as a self-evolving architecture that integrates generative AI (GenAI) for scenario synthesis and agentic AI for autonomous decision-making.
