摘要
混合动力汽车的节能减排潜力取决于动力系统匹配的合理与否。为兼顾目标工况和动力性指标对动力系统的要求,对常用的理论匹配法进行了分析,提出了工况匹配法。基于Cruise进行了前向仿真,理论匹配法目标工况跟随较差,工况匹配法既能满足动力性指标要求,在目标工况上运行又具备优异的跟随性能和良好的燃油经济性。
The ability of fuel economy with reduced emissions for hybrid electric vehicle strongly depends on their powertrain.In order to match the powertrain that operates efficiently on the target driving cycle,the popular theoretic matching method is analyzed.According to simulation results with forwards simulation platform of Cruise from AVL,the powertrain matched with the theoretic matching method is able to meet the requirements of economic performance,but is not able to meet the requirements of the target driving cycle.The matching method based on driving cycle proposed in this paper not only meets requirements of the dynamic performance,but also operates efficiently on the target driving cycle.
