This book offers a complete yet approachable guide to software-defined vehicles (SDVs), explaining how modern cars are evolving from fixed-function, hardware-centric machines into continuously updatable software, data, and service platforms. It shows what that transformation means for engineers, architects, product leaders, researchers, and educators, beginning with SDV fundamentals and tracing the industry’s shift from legacy ECU-heavy designs to domain, zonal, and centralized architectures. From there, the book explores the technologies that make SDVs possible: automotive silicon, operating systems and middleware—from AUTOSAR and RTOS to Linux and Android Automotive—in-vehicle networking, V2X communication, cloud and edge platforms, digital twins, CI/CD workflows, OTA update pipelines, and the growing role of AI in perception, analytics, personalization, and fleet-scale learning. It also examines the disciplines required to make SDVs viable in production, including functional safety, SOTIF, cybersecurity, software update governance, and global regulatory compliance. Beyond engineering, the book shows how telemetry, connected services, subscriptions, data-driven offerings, and platform ecosystems are reshaping the automotive business model and creating new paths to monetization. Real-world OEM and Tier-1 examples, worked exercises, design checklists, and "Critic’s Notes" ground each topic in practical trade-offs, while the closing chapters map emerging career and skills pathways across engineering, research, and business. You Will: Understand the full SDV stack—from E/E architectures and automotive silicon to middleware, networking/V2X, cloud/edge platforms, AI/data pipelines, and OTA update systems Evaluate the trade-offs behind zonal and centralized architectures, digital-first development, safety-security co-engineering, and compliance with ISO 26262, ISO 21448, ISO/SAE 21434, UNECE WP.29, and ISO 24089 Analyze how SDV platforms create value through connected services, telemetry, digital twins, subscriptions, data-driven business models, and the emerging roles and skills required across engineering, research, and business This book is for: Embedded, software, systems, middleware, cloud/DevOps, safety, and cybersecurity engineers; E/E and platform architects; automotive product and program managers; and graduate students, researchers, and educators seeking a system-level view of software-defined vehicles.
