混合动力汽车制造商在考虑成本和驾驶性能的情况下，面临发动机小型化和电动混合动力的多目标非平凡优化问题。这个大小问题的解决方案通常是通过启发式设计方法来实现的。然而，为了获得全局最优解，在优化理论设置中形式化的设计方法是必要的。在本文中，我们提出了一个框架的最优尺寸的混合动力传动系统部件。这个框架是在标准优化理论中构建的。此外，它是灵活的，以便轻松地包括任何数量的目标，如最小化燃料消耗，混合动力成本，排放水平和（或）加速性能最大化。基于这个框架，我们展示了许多技术和工具来分析、接受、改进或拒绝针对最优规模问题提出的解决方案。
Automotive manufacturers of hybrid electric vehicles are confronted with the multi-objective non-trivial optimization problem of engine downsizing and electric hybridization under consideration of cost and drivability. Solutions to this sizing problem are typically reached by heuristic design methodologies. However, a design approach formalized in an optimization theoretical setting is necessary in order to obtain globally optimal solutions. In this paper, we present a framework for optimal sizing of hybrid electric drivetrain components. This framework is cast within standard optimization theory. Moreover, it is flexible in order to easily include any number of objectives, such as minimization of fuel consumption, cost of hybridization, emission levels and (or) maximization of acceleration performance. Based on this framework, we demonstrate a number of techniques and tools to analyze, accept, improve, or reject the proposed solutions to the optimal sizing problem.
