混合动力系统参数优化匹配研究

Research of Parameters Match,Optimization and Simulation for Power System of Hybrid Electric Bus

以XMQ6103GF2城市公交客车为改造对象,为提高并联混合动力车辆(PHEV)动力系统的内燃机、电池、电机之间工作的协调性,解决整车的动力性、经济性、排放性及车辆成本问题,提出一种以动力系统功率最小化为目标,动力性能指标为约束条件的参数优化匹配方法。该参数匹配方法包括初步设计、参数优化和性能校核三个部分。在MATLAB平台下,采用ADVISOR的电辅助控制策略进行仿真,仿真结果验证了该方法的有效性。

With XMQ6103GF2 urban bus as the research object, to improve harmony of engine, batteries and electromotor of Parallel Hybrid Electric Vehicle （PHEV） and to achieve economical fuel and low emission for vehicle, the method of parameters match is studied. Requiring minimizing power and performance index, a method to match and optimize the parameters is introduced. The design is composed primary calculation, optimization and simulation. Use MATLAB and ADVISOR to simulate and analysis. From the simulation results, the control strategy is proved to be more effective.
