On the basis of the System Engineering concept, a methodology is developed in order to create a standard procedure for the design of a system. The approach uses the Hybrid V-cycle and the Modular Technical Model. The Hybrid V-cycle is a guideline for the development process composed of different steps that have to be executed considering the appropriate computing platform: DWS (Development Workstation), RCP (Rapid Control Prototyping) platform and VMU (Vehicle Management Unit) . The Modular Technical Model is a tool that is used along with the Hybrid V-cycle. It aims at decomposing the system into its parts (modules) to differentiate the various disciplines involved into the design process.
