面向未来的低碳出行社会，新型小型电动汽车（ev）近年来得到了积极的发展。为了降低各种实际驾驶条件下的能耗，需要考虑轮胎特性、机械损耗和电气损耗带来的整体运行阻力。本文介绍了一种新型电动汽车系统性能的基于模型的开发方法。利用Modelica软件建立了考虑车辆动力学和能耗的整车模型。采用整车模型，对整车部件的结构、规格和控制进行了研究，以寻求既满足整车能耗又满足整车动力学的解决方案。最后指出了采用直接偏航力矩控制在车辆稳定性和能量消耗之间以及驾驶员工作负荷和能量消耗之间的平衡。
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. In this paper, modelbased 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. Finally trade-off between vehicle stability and energy consumption and also between driver workload and energy consumption by using direct yaw moment control was indicated.
