摘要
针对燃料电池汽车研发中的动力系统参数匹配问题,基于整车动力性和经济性同步提升的目标,提出多指标的整车动力系统参数匹配设计方法。为了加快计算经济性指标,针对燃料电池汽车提出了快速动态规划算法,通过缩小搜索域和降低维度,使得计算耗时由传统动态规划算法的393. 33 min缩短到12. 52 min。以燃料电池汽车的动力性能和经济性能作为设计指标,通过计算初步确定动力系统参数范围,并利用正交试验法进行参数匹配优化设计。试验结果表明,按照所设计的动力系统参数,各项性能指标相比原车均有明显提升。
In view of powertrain parameter matching of Fuel Cell Electric Vehicles(FCEV),a multi-index parameter matching design method of the powertrain was discussed based on the goal of optimizing the vehicle dynamic performance and economic efficiency.In order to accelerate calculation of economic performance,the fast dynamic programming algorithm was proposed.By narrowing the search domain and dimensionality reduction,the time of calculation was shortened from 393.33 minutes to 12.52 minutes.Taking dynamic and economic performance as indicators,the range of the powertrain parameters was preliminarily determined.Then the orthogonal table was designed based on orthogonal optimal design theoretic.The results show that according to the parameters designed,the dynamic and economic performance are obviously improved compared with the original vehicle.
