| 摘 要： | 对基于超级电容的混合动力客车(hybrid electric bus,HEB)进行了混合动力传动系多目标参数优化设计。通过CRUISE建立HEB整车仿真模型和传动系多目标参数优化模型,以等效燃油消耗量和加速时间为优化目标,同时运用带精英策略的非支配排序遗传算法(NSGA-Ⅱ)和iSIGHT优化软件对HEB传动系参数进行多目标优化,并进行了HEB性能仿真分析。结果表明，与优化前相比,优化后的等效燃油消耗量降低了 7.8%，连续换挡加速时间减少了6.5%。 |

| Abstract: | Based on the characteristics analyses of a HEB of super capacitor,a multi-objective parameter optimization for HEB powertrain was designed.The multi-objective optimization model for HEB powertrain was established via CRUISE.Taking fuel consumption and acceleration time of HEB as targets of the optimization,the elitist non-dominated sorting genetic algorithm(NSGA-Ⅱ) was applied to optimize the powertrain parameters of HEB by a optimization software iSIGHT.The performance simulations were carried on an instance HEB,the results show that the fuel consumption is reduced by 7.8% and acceleration time is reduced by 6.5%,compared with the road testing of the instance HEB. |
| Keywords: | hybrid electric bus(HEB) powertrain multi-objective genetic algorithm parameter optimization |
