Rationale: Increasingly, global vehicle engineering teams span domains of engineering and physics within organizations and include external collaborations between commercial businesses (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 simulation 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 testing 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. 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, 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, and (5) reduce costs.
