轿车混合动力传动系统排放特性的仿真

Exhaust Characteristics Simulation of the Hybrid Electric Car

节能和环保是新世纪人类急待解决的两大主要难题 由于轿车在全球汽车保有量中占有 80 %左右的比例 ,开发新型节能传动系统和清洁燃料已经成为当务之急 混合动力传动系统被认为是目前解决节能和环保问题的有效途径之一 本文在介绍总结传统混合动力传动系统的基础上 ,提出了一种新型的最小化形式轿车混合动力传动系统 介绍了其结构原理和控制策略 ,建立了最小化形式轿车混合动力传动系统排放特性的数学模型 利用编制的计算机仿真程序 ,对最小化形式混合动力传动系统轿车的排放特性进行了仿真 仿真结果显示 。

Saving energy and protecting the environment are regarded as two main problems f or the world . Because cars amount to about 80% of the existing automobiles in the world, it is urgent to develop new energy-saving powertrain and clear fuel. The hybrid powertrain is regarded as on e of the ways to save energy and protect the environment. When traditional hybr id powertrains are introduced, a new minimal hybrid electric car is proposed. Af ter its principle and its control strategy are introduced, its exhaust model is established. Also, a simulation is performed with the simulation program edited by the author. The simulation result shows that the minimal hybrid powertrain c an reduce exhaust significantly.
