Tak ing mechan ical and electrical drive system for an electric car as an examp le, sofwt areADVISOR w as emp loyed to conduct smi ulation analy sis of drive cycle of the dynam ic and econom ic perform ance; the resu ltw as in accordancew ith actual data. Both the smi u la tion result and test data ind icated that dynam ic and econom ic perform ance of the vehicle cou ld m eet the requ irem ents; there w as no resonance of the powertrain system; feasib ility m atch m ethod w as verified.
