Modelica Usage in Automotive Problem at Chalmers

Modelica, and previously Dymola, has been used at Chalmers University of Technology, at Machine & Vehicle Design (MVD) and at Control & Automation Laboratory (CAL), for automotive engineering research for some years, 1995-2000. Primarily it has been used for automotive powertrain engineering, both fuel consumption and emissions analyses and faster transients, like take-offs, gearshifts, shunt and shuffle etc. The paper presents the basic motives for equation oriented modelling at Chalmers, both in research projects as well as in undergraduate/graduate education. The paper also gives an introduction to some of the present research projects involving Modelica. The research projects includes mainly powertrain modelling of both conventional powertrains as well as hybrid powertrains. The paper tries to point out how Modelica have been used and what future use that could been foreseen. In undergraduate teaching Modelica/Dymola has been used for studying vehicle handling and will be introduced in modelling courses at CAL this winter.
