Guidelines and challenges for composing and synchronizing real-time software components through virtual platforms in vehicular systems

This work investigates the composition of interdependent software components on a shared platform from a timing perspective. Because we consider software components for vehicular systems, which are often sensitive to timing, the individual components and the composed system require timing analysis. In order to support independent development of components, the real-time systems community proposed hierarchical scheduling frameworks (HSFs). HSFs in essence provide a virtual platform to individual components, including well-defined protocols for their synchronization. In this paper, we give an overview of recent research for applying HSFs into in-vehicle technology standards and we look ahead to some future challenges regarding the safety certification of such systems.
