To cope with demands for future low carbon society; development of new-type small electric vehicles (EVs) becomes very active. To reduce the energy consumption in various actual driving conditions; considering overall running resistance such as aero-dynamic resistance; tire rolling resistance including cornering drag; mechanical and electrical losses; etc. will be necessary. On the other hand; to cope with reduced stability against external disturbances such as side wind because of the light weight; it was clarified that additional control of direct yaw moment is effective. In this paper; model-based development of a new electric vehicle using Modelica is described. Full vehicle model considering both vehicle dynamics and energy consumption was developed and utilized to investigate the best possible solutions for both basic design of the vehicle and design of the control system.
