This paper outlines the development and implementation of a vehicle model architecture for hybrid vehicle modeling. The architecture is based on the VehicleInterfaces library with significant extensions to enable more flexible; configurable implementations for hybrid vehicle applications. Additional elements are added to the interfaces and architecture to allow more flexible electrical system modeling and more detailed thermal modeling. Four different hybrid vehicles are implemented as sample applications using the newly-developed architecture. The scheme and canonical library structure for the component; subsystem; and system models is also discussed to document a mechanism for user-friendly handling of parameterized models and fully-implemented models in a complex model architecture with extensive model data. Models and simulation results are shown for the Toyota Prius; Lexus RX400h; a concept hybrid sedan; and a concept hybrid sport utility vehicle (SUV). Extensions to VehicleInterfaces are also proposed to enhance the library to include additional features to improve support for future conventional and hybrid vehicle modeling efforts.
