摘　　要：在根据性能要求对某款增程式电动客车进行参数匹配和部件选型的基础上,分别借助AVL cruise软件和Matlab/Simulink软件搭建整车模型和控制策略,根据设定条件对车辆的三种工作模式进行切换,通过PID控制对增程模式下发动机的转速进行控制,从而达到车辆运行需求功率与发动机发出功率的动态平衡。通过AVL cruise和Matlab/Simulink的联合仿真,对所搭建控制策略的可行性进行验证分析。仿真结果表明,所搭建的控制策略实现了对整车的控制,达到预设目标,为进一步研究增程式电动客车的控制策略提供了理论依据。On the basis of parameter matching and component selection of an extended-range electric bus,according to performance requirements,the vehicle model and control strategy are built by AVL cruise software and Matlab/Simulink software respectively.The three working modes of the vehicle are switched according to the set conditions.The PID control is used to control the engine speed in the extended range mode,so as to strike a dynamic balance between the vehicle running demand power and the engine output power.Through the joint simulation of AVL cruise and Matlab/Simulink,the feasibility of the established control strategy is verified.The simulation results show that the established control strategy can be used to realize the control of the whole vehicle,achieve the preset target.The theoretical basis is provided for further research on the control strategy of the extended-range electric bus.
