Abstract

A method for automatically generating a multi-component multilevel model for simulation of an automotive propulsion system and/or subsystem. The method comprises a capture component and a build component. The capture component operates to automatically parse all relevant information of an existing model and to generate one or more files indicative of the systems and subsystems of the model. The files are created such that they may be efficiently searched, manipulated, and applied for subsequent use in various user defined models created through the build component. The build component obtains the information in the one or more files and additional user defined files based on user selections to automatically create an executable model ready for analysis.

converting the automotive propulsion information from a first format to a second format;

for each level of the plurality of levels;

storing the information describing the configuration of each of the one or more automotive subsystems and each of the one or more peripherals contained within the each level in the second format in a configuration file associated with the each level; and

storing the information describing the layout of each of the one or more automotive subsystems and each of the one or more peripherals contained within the each level in the second format in a layout file associated with the each level;
