Multi-objective Optimization Method for Powertrain Parameters of Electric Vehicle

  • 摘要: 提出一种以电动汽车的综合性能需求为驱动,基于质量功能展开和径向基函数的动力系统参数多目标优化方法。以包含成本、工况能耗和续驶里程等的综合性能最优为目标、以动力系统部件特征参数为设计变量,建立动力系统参数多目标优化的数学模型;基于质量功能展开建立整车性能需求和技术特性指标的耦合模型,确定子目标函数的权重系数;基于Modelica建立整车性能仿真模型并构建工况仿真的径向基函数响应面模型;采用模拟退火算法进行动力系统参数的综合目标优化设计。以某款电动汽车进行实例验证,优化方案的车辆综合性能提升了6%,证明了研究方法的有效性。
