Hybrid Electric Vehicle Modeling and Analysis in Generic Modeling Environment

This paper introduces a new modeling methodology based on generic modeling environment (GME), a software suitable for modeling and analysis of physical systems. Once a metamodel is configured in GME using unified modeling language (UML) and object constraint language (OCL) for a specific engineering domain, application level system model can be constructed and analyzed. UML and OCL can facilitate domain experts' knowledge to be represented and enforced during design process. These concepts are illustrated through a domain-specific modeling environment for electric and hybrid electric vehicles. In particular, this environment is used to evaluate the dynamic performance of a battery electric vehicle design, as shown by some preliminary simulation results
