摘　　要：为了提高整车经济性和降低排放,设计适合于城市工况的P-HEV客车动力系统的控制策略。首先进行P-HEV客车动力系统关键部件设计,并在AVL Cruise软件中构建P-HEV客车的整车模型。通过分析车辆在各个工作模式下的能量流动,设计基于规则的逻辑门限值的控制策略,在Matlab/Simulink中建立P-HEV客车动力系统控制策略的仿真模型。最后通过Cruise与Matlab/Simulink的联合仿真,检验控制策略的效果。仿真结果表明,与HEV相比,在满足动力性要求的基础上,能量消耗减少了38.45%,尾气中HC,CO和NOX的排放分别减少了33.39%,41.48%和36.54%。To meet the goal of improving economic performance and reducing emissions of the vehicle, the control strategy of P-HEV bus power system which is suitable for urban conditions is designed. Firstly, the key components of the P-HEV bus power system are designed and the P-HEV bus model in software AVL Cruise is built. Rule-based logic threshold control strate- gy is designed through the analysis of the energy flow of vehicles in each operating mode, and simulation model of the P-HEV bus power system control strategy is established in Matlab/Simulink. Finally, a Cruise and Matlab/Simulink simulation is built to inspect and control the effects of the strategy. The simulation results show that, compared with HEV, energy consumption is re- duced by 38.45%, among exhaust gas, the emissions of HC, CO and NOx are respectively reduced by 33.39%, 41.48% and 36.54% on the basis of meeting the power requirements.
