Powertrain system modeling and performance simulation about parallel-series hybrid electric vehicle

为了更好地评价电动汽车各种性能,在对传统轿车驱动系统的方案和传递路线进行设计和动力源优化匹配的基础上,依据整车结构,通过对传动系统进行设计、优化和匹配的同时,对电机组件进行选型与匹配,利用Matlab/Simulink软件,对混合动力电动汽车的传动系统和控制策略进行仿真建模,在CYC_UDDS和CYC_1015循环工况下对整车动力性和排放性能进行了仿真研究。结果表明:在保证原有车型动力性的前提下,节油率分别可以达到24%和30%,排放性能也得到了极大的改善。这对中国开展电动汽车仿真研究具有一定参考作用。

In order to better evaluate the various performance of the electric vehicle,based on the design of traditional vehicle driving system and transmission line and its power optimisation,the motor component was selected and matched after the design,optimization and match of the driving system according to the vehicle structure,and then the drive system and control strategy of the hybrid electric vehicle were modeled and simulated in Matlab/Simulink environment.The performance of the power and emission was simulated and researched under the CYC_UDDS and CYC_1015cycle conditions.The results show that the premise of dynamic performance,oil saving rate can reach to 24%and 30%respectively,and the emission performance has been greatly improved in the original models.It provides some references for the study on the simulation of electric vehicle in our country.6tabs,20 rigs,11refs.
