Longitudinal Vehicle Dynamics Modeling on the Basis of Engine Modeling

Today, an increasing emphasis is being placed on vehicle transient operation improvement to accomplish better drivability and lower emission and fuel consumption. In this regard, dynamic simulatory model of powertrain-vehicle is a stepping-stone on the path to achieve this goal.In this study, a complete powertrain-vehicle model has been developed to predict vehicle performance and fuel consumption, with careful attention given to the engine dynamics (dynamic of air and fuel flows into the intake manifold, and crankshaft transient response). The model has been experimentally identified and validated for “Paykan 1600i”.Since there is a good agreement between vehicle test and simulation results, the model proposed in this study can be used in design and performance evaluation of vehicle powertrain system.
