Software Defined Vehicles (SDV) represent a paradigm shift in automotive engineering, with varying interpretations from architecture changes to hardware-software separation. While SDV aims to leverage software development methodologies in the automotive industry, this alone cannot address today’s mounting challenges. Modern vehicles face unprecedented complexity with interconnected systems, stringent regulations, and cybersecurity mandates. Engineering efficiency improvements have fallen short of actual requirements by a factor of 3-8, as highlighted by recent industry studies.
