Composability in the Time–Triggered Architecture

The next generation of automotive control systems will consist of a set of networked electronic control units (ECUs) that operate in tight coordination to achieve the desired optimal control of the vehicle. The design of these systems must be guided by a composable system architecture that supports the constructive integration of the independently developed components. This paper discusses the four principles of composable architectures and shows how the interoperability of the ECUs is achieved in the time–triggered architecture.
