An Architectural Framework for Virtual Prototyping of Next Generation Combat Vehicles

Project started September 2019.

The proposed research aims to facilitate the exploration of new architectures for Next Generation Combat Vehicles (NGCV) through virtual prototyping. By using a formal modeling language (i.e., SysML) for capturing the architectures of vehicles, commonality between vehicle systems and their corresponding simulation models can be exploited to compose models of subsystems and components —both hardware and software—into a full vehicle-level virtual prototype. This would allow for the exploration of a larger number of vehicle architectures by significantly reducing the amount of time and effort needed to generate a virtual prototype, or alternatively, allow for a more thorough analysis and virtual validation of any given vehicle system. In addition, by referencing all models to a “single source of truth” (i.e., the architecture model) one can avoid inconsistencies in the simulation model increasing the confidence that the simulation results can be trusted as representative of the actual vehicle system.

The research objectives of this project are to determine the scope and limitations of model composition, and the compositionality of a SysML-based architectural description language for autonomous vehicles, as applied to Next Generation Combat Vehicles. This work is expected to result also in an infrastructure framework that can be used to generate virtual prototypes at reduced effort and time, and in a way that guarantees internal consistency. Since the architecture and simulation models are both generated from a single source of truth, inconsistencies can be avoided. It is anticipated that this infrastructure could also be used to perform tradestudies across the space of system architectures, and once a systems architecture has been selected, in a continuous integration tool (such as Jenkins) to perform virtual validation of system requirements.
