使用Modelica进行物理建模所带来的真实的强大功能和灵活性源于将非因果方法与各种工程领域中的标准连接器定义相结合来制定物理连接。这些特性很重要，因为它们有助于避免先验因果关系假设（促进组件的重用），并确保连接之间的物理兼容性。然而，复杂系统通常是由几个复杂的，多域的子系统与众多的连接器。这样的系统还受益于具有标准化的子系统接口定义。本文将集中在车辆系统应用的车辆模型架构的初步建议。最后，我们希望其他小组对这一建议的反馈进行车辆建模，将导致一个共识，适当的子系统接口，使我们能够实现相同的灵活性和可重用性水平的车辆子系统模型，我们目前与组件级模型。
The real power and flexibility that comes from using Modelica for physical modeling stems from the combination of the acausal approach to formulating physical connections combined with sets of standard connector definitions in various engineering domains. These features are important because they help avoid a priori causality assumptions (which promotes reuse of components) and ensure physical compatibility across connections. However, complex systems are generally made up of several complex, multidomain subsystems with numerous connectors. Such systems also benefit from having standardized subsystem interface definitions. This paper will focus on an initial proposal for a vehicle model architecture for vehicle system applications. Ultimately, we hope that feedback on this proposal from other groups doing vehicle modeling will lead to a consensus on the appropriate subsystem interfaces such that we can achieve the same level of flexibility and reusability for vehicle subsystem models that we currently have with component level models.
