The complexity of automotive powertrains is increasing. As a result it’s becoming increasingly difficult for engineers to determine the optimum specification for the system. The proliferation of control systems also adds to the complexity of the task and increasingly simulation is being used to assist in the development of new products.
A model has been developed to enable component parameter studies and desktop calibration of driveability attributes using Dymola and Modelica. The model included the automatic translation of an existing, validated engine model from Simulink into Modelica using Simelica. The correlation process used is described and the results presented.
