摘　　要：以一款10.5 m的混合动力公交客车作为研究对象,目的在于保证整车动力性的前提下提高整车燃油经济性。采用基于规则的逻辑门限控制方法,以Matlab/Simulink为平台,设计了以整车需求转矩和模式判别及转矩分配为主要模块的控制策略,并在AVL CRUISE平台中搭建了整车模型以及与控制策略相应接口的模块,在中国典型城市公交循环工况(CCBC)下进行了联合仿真。结果表明了,所设计的混合动力公交客车的控制策略能够在保证整车动力性要求的基础上,使得整车有较好的节油率,经济性良好。This paper takes a 10.5m hybrid bus as the research object,aiming to improve the vehicle fuel economy under the premise of ensuring the vehicle dynamic performance.Based on the rule-based logic threshold control method,a control strategy is designed based on the MATLAB/Simulink platform.The vehicle model and the corresponding interface module with the control strategy are built in the AVL cruise platform,and the joint simulation is carried out under the CCBC of typical Chinese cities.The simulation results show that the control strategy of hybrid electric bus designed in this paper can ensure the vehicle power requirements,make the vehicle has a good fuel saving rate and good economy.
