混合动力汽车行驶工况的仿真分析

Simulation Analysis on Driving Cycle of a Hybrid Electric Vehicle

汽车的实际行驶条件对汽车性能具有直接影响。对于混合动力汽车,其部件的选型以及控制策略的制定都与道路行驶工况密切相关。文章对汽车行驶工况做了相应的分析,利用GT-DRIVE软件对某微型混合动力汽车进行了建模与仿真。仿真结果表明,在经济性方面混合动力汽车比传统汽车有明显的优势。如何更好地分配混合动力汽车功率将是混合动力汽车研究的重点。

Vehicle performance is influenced by actual driving condition directly.For a hybrid electric vehicle,selection of its componemnts and formulation of control strategy are closely related to road driving cycle.Driving cycle of a vehicle is analyzed in this paper.modeling and simulation of a mini hybrid electric vehicle is comducted by using GT-DRIV.The simulation results show that the hybrid electric vehicle has obvious advantages than traditional vehicle in fuel economy.Better electric distribution will be the key point in hybrid electric vehicle design.
