摘要
为了提高混合动力汽车的燃油经济性及降低汽车的尾气排放,从中国城市典型工况的动力需求出发,以单行星排10.5m城市公交客车为研究对象,采用MATLAB软件建立整车经济性计算模型;然后,对比分析客车在单一目标控制策略和双层筛选全局优化控制策略下的节油效果.研究结果表明:在中国城市典型工况下,客车采用双层筛选全局优化控制策略比采用单一目标控制策略节油效果更为显著,节油率高达4.4%.
In order to improve the fuel economy and reduce the exhaust emissions of hybrid vehicles,a single planetary row 10.5 m city bus was taken as the object to conduct the research.Starting from the dynamic demand of typical urban conditions in China,the MATLAB software was used to establish the economic calculation model of the whole vehicle.The fuel economy effect of the passenger car was comparatively analyzed under the single target control strategy and the double-layer screening global optimization control strategy.The analysis results showed that the fuel saving of the double-layer screening global optimization control strategy in typical urban conditions in China is 4.4%,which is more distinct than that of single target control strategy.
