摘　　要：以某款增程式电动客车作为研究对象,根据设计指标以及给定的基本参数,对增程式电动客车动力系统进行了选型和匹配。设计了基于逻辑门限值的控制策略,并利用CRUISE软件对整车的动力性和经济性进行了建模和仿真。仿真结果表明,汽车动力系统的参数选型和匹配以及控制策略的设计都是合理的。使用蚁群算法对控制策略关键参数进行了优化,优化后燃油经济性提高了9.74%。An extended range hybrid electric vehicle is taken as the research object. According to the specifications and the given basic parameters, the power system of the extended-range hybrid electric bus is selected and matched. Then a control strategy based on the regular logical gateway is created and CRUISE is used for modeling and simulation for the power and economy performance of the bus. The simulation results verify that the selection and matching of the power system are reasonable, as well as the design of the control strategy. The key parameters of the control strategy are optimized by the algorithm of ant colony, after which the fuel consumption of the bus is improved by 9.74%.
