Powertrain Simulation for Coaxial Series-Parallel Hybrid Electric Vehicle Based on Advisor

以同轴式混联混合动力汽车为对象,在分析其动力系统运行模式及控制策略的基础上,进行了动力部件参数匹配计算,基于Advisor软件的二次开发建立了动力性能仿真系统.在选定的城市循环工况下,对车辆动力性能和燃油经济性进行仿真.通过分析SOC值变化和动力部件转矩关系,验证动力系统的可行性及仿真系统的准确性,为同轴式混联混合动力汽车开发提供技术支持.

Using the coaxial series-parallel hybrid electric vehicle as the object and on the basis of the power train structure analysis, the operating mode and control strategy are introduced. The basic parameters of power components are calculated and the power train simulation system is established based on the secondary devel- opment of Advisor. Then the simulation of the vehicle dynamic performance and fuel economy are completed under the selected urban cycle condition. The result analysis of SOC value change and power unit torque relations verifies the feasibility of the power train and the accuracy of the simulation system, and provides the tech- nical support for the coaxial series-parallel hybrid electric vehicle development.
