5、odel Architecture and Interfaces Recommended Practice for Ground Vehicle System and Subsystem Dynamical Simulation RATIONALE Increasingly, global vehicle engineering teams span domains of engineering and physics within organizations and include external collaborations between commercial businesses (

6、original equipment manufacturers (OEMs), and suppliers), government agencies, and research institutions. For increased efficiency, reduced costs, faster design iterations, and fewer hardware prototypes, these teams use math-based engineering methods to build and test virtual ground vehicles in simul

7、ation environments. These types of inter-organizational engineering collaborations require a common shared simulation model for an entire ground vehicle system and/or the related subsystems of which it is composed. Use of dynamical modeling and simulation for virtual engineering development and test

8、ing of the functional performance of ground vehicles by inter-organizational teams has increased and resulted in a need for standardizing the architecture and interfaces of a ground vehicle system model by partitioning it into subsystem models to enable plug-and-play of subsystem simulation models.

9、A standardized ground vehicle system model with an architectural structure partitioned into subsystem models, and with defined subsystem model interfaces enables: (1) model reuse, (2) division of modeling tasks across multifunctional teams, (3) parallel model development, verification and validation

10、, and (4) rapid and efficient integration of subsystem models for reduced development time and costs. The recommended practice for model architecture and interfaces will: (1) create a common language, (2) increase productivity of processes, (3) promote uniform testing, (4) permit common interfaces,

11、and (5) reduce costs. FOREWORD The word system is not an absolute term; it is a relative term, depending upon how it is used. Since, a system is an integration of parts assembled to perform a common functional purpose, and systems can be integrated together to form a larger system or to perform a gr

12、eater purpose; then, a system taken as a whole unit or module can be called a system or a subsystem depending upon the context in which it is used. Thus, the use of the words system model and subsystem model are context or application sensitive, relative to where the model of a system module is used

13、 in a simulation model. If a system model module describes or models everything that is being simulated; it is the top-level model and the main subject of the simulation. Then, it is called a system model or the top-level system model. And, if it is one of the many interconnected supporting system m

14、odel modules that contribute to the functionality of the entire simulation model under study; then, it is called a subsystem model. In general, an architectural description for a simulation model of a system is a description of the structural organization of the fundamental building blocks from whic

15、h it is assembled. The architecture description defines all of the fundamental subsystem building blocks, the purpose and function of the subsystems, and the connections between subsystems. Subsystem interfaces define the physical quantities and information that are passed between the subsystems. To

16、gether, the description of the model architecture and interfaces defines how to assemble and connect these subsystem blocks together in order to construct or build the overall system model.
