Vehicles are evolving from hardware-centric machines into software-defined vehicles (SDVs)—connected, automated, and continuously adapting socio-technical systems. While new technical capabilities and market pressures drive rapid innovation, the industry's real challenge is reinventing vehicles to extend far beyond basic human transportation.


This book argues that fully realizing the potential of SDVs requires treating user-centered design as a core guiding principle rather than a mere development feature, ensuring integrated experiences that truly fit users' daily lives.


To this end, the book examines SDVs from a user-centered perspective to build a comprehensive Human Systems Integration (HSI) framework for R&D. This framework aims to help automotive ecosystems transition into dynamic, evolving platforms that align with individual and societal needs.
