For future low carbon mobility society, new-type small electric vehicles (EVs) are developed actively in recent period. To reduce the energy consumption in various actual driving conditions, considering overall running resistance from tire characteristics, mechanical losses and electrical losses is necessary. Also, to cope with reduced stability against external disturbances because of the light weight, it is necessary to apply vehicle dynamics control utilizing direct yaw moment control. In this paper, model-based development of system performance of a new EV is described. Full vehicle model considering both vehicle dynamics and energy consumption was developed using Modelica. Research for both structure and specification of components of the vehicle and also of the control were performed to find the solution to satisfy both energy consumption and vehicle dynamics by using the full vehicle model.
