Dynamic Computer Simulation of a Vehicle with Electronic Engine Control

A computer model which simulates the dynamic interactions among the components of the engine, electronic control system, and drive train is described. The model consists of a combination of experimental data and mathematical submodels representing components and physical phenomena. The model also contains a simulation of the human driver which can follow the FTP speed trace, and which can perform a variety of other tests. Use of the model is demonstrated with a study of air/fuel transients due to manifold filling.
