摘　　要：介绍了混合度的概念及它对设计混合动力车的重要作用。以某种并联型混合动力车为研究对象,根据该车的特点选择了适合于它的控制策略,并用系统仿真软件MATLAB/Simulink建立了该车的仿真模型,输入循环工况研究其速度特性、动力性、油耗及SOC的变化规律。结果表明,仿真车速能够很好的跟踪循环工况,从而验证了仿真模型的正确性。该模型可以为混合动力车的进一步优化设计奠定基础。The paper presents the concept of DOH (Degree of Hybridization) and it playing AN important role in designing Hybrid Electric Vehicle (HEV). Based on the configuration and control strategy of a kind of parallel hybrid electric vehicle, a simulation system has been developed utilizing the Matlab/Simulink toolbox. Simulation results, including the speed of the vehicle, dynamic characteristics, fuel consumption and the state of charge (SOC) of the battery, etc over the EPA Urban Dynamometer Driving Schedule demonstrate the correctness and potential of the simulation model. This study lays a foundation for further optimal design of a hybrid electric vehicle.
