Abstract

The investigation studies about increasing powertrain efficiency and reducing exhaust emissions and fuel consumptions have been focused on for hybrid vehicles in few decades. However, the investigations are related with improvement of an individual powertrain component or energy management strategy for hybrid vehicles. Therefore, this study investigates the effects of the layout of the three-speed transmission and various gear selection procedures on vehicle performance, component efficiency and exhaust emissions for same vehicle parameters, gear ratios and capacity of the components in a parallel hybrid powertrain. Three design alternatives have been modelled and powertrain simulations have been performed according to the three different drive cycles as New European Drive Cycle (NEDC), Federal Test Procedure (FTP-72) and Istanbul Drive Cycle (IDC) using MATLAB® - Simulink® environment. The main simulation results are given for vehicle performance (acceleration, grading capacity and maximum speed) and component efficiencies (battery and electric motor), brake specific fuel consumption and exhaust emissions of the engine as CO2, CO, HC and NOx during the operation on the three-drive cycle. The simulation results showed that better vehicle performance, fuel consumption and exhaust emissions can be achieved separately by changing the layout of the transmission in parallel hybrid vehicles.
并联混合动力汽车变速器布局对动力系统效率、性能和废气排放影响的研究
近几十年来,提高动力系统效率、降低尾气排放和燃油消耗的研究一直是混合动力汽车的研究热点。然而,这些调查与改进单个动力总成组件或混合动力汽车的能源管理策略有关。因此,本研究考察了在相同车辆参数、传动比和并联混合动力系统中,三速变速器布局和不同档位选择程序对车辆性能、部件效率和废气排放的影响。采用MATLAB®- Simulink®环境,对三种设计方案进行了建模,并根据新欧洲驱动循环(NEDC)、联邦测试程序(FTP-72)和伊斯坦布尔驱动循环(IDC)三种不同的驱动循环进行了动力系统仿真。给出了车辆性能(加速、分级能力和最大速度)和部件效率(电池和电动机)、制动比油耗和发动机在三驱循环运行过程中的CO2、CO、HC和NOx等废气排放的主要仿真结果。仿真结果表明,通过改变并联混合动力汽车的变速器布局,可以分别获得更好的整车性能、油耗和尾气排放。
