并联式混合动力汽车最优控制方法

Optimal Control Method for Parallel Hybrid Electric Vehicle

首次将ADVISOR和AMESim软件联合进行建模仿真,根据并联式混合动力汽车的发动机和驱动电机的各项参数,在ADVISOR和AMESim中搭建并联式混合动力汽车的模型并进行仿真分析,使用AMESim中的混合优化工具HOT(Hybrid Optimization Tool)对并联式混合动力汽车模型进行优化,在NEDC工况下对优化后模型进行仿真。结果表明:并联式混合动力汽车的燃油经济性、动力性和乘坐舒适性都得到了提升,与优化前相比最高车速和燃油经济性显著提高,此优化方法对后续串联式和功率分流式混合动力汽车的优化有一定的参考意义。

For the first time,the ADVISOR and AMESim software were combined for modeling and simulation according to the engine and drive motor parameters of the parallel hybrid electric vehicle.According to the parameters of the engine and driving motor of the parallel hybrid electric vehicle,the model of the parallel hybrid electric vehicle was built and simulated in ADVISOR and AMESim.Then,HOT(Hybrid Optimization Tool)in AMESim was used to optimize the model of parallel hybrid electric vehicle,and then simulate the optimized model under NEDC conditions.The simulation results show that the fuel economy,power and ride comfort of parallel hybrid vehicles have been improved.Compared with before optimization,the maximum speed and fuel economy have been significantly improved.This optimization method has certain reference significance for the subsequent optimization of series and power split hybrid vehicles.
