What if Cars could be as Easy to Program as Smartphones are Today?

This paper approaches the development of Software-Defined Vehicles from the angle of efficient software development. We analyze the requirements for Software-Defined Vehicles, analyze state-of-the-art and discuss current challenges and illustrate these using the automotive development V-cycle as an example. We propose a common cross-domain as SDK as the solution to improve the efficiency of software development and as the enabler for a common mobility digital ecosystem.
