基于ADVIS0R的混合动力SUV

Hybrid SUV Based on ADVISOR

在我国SUV保有量迅速增加,油耗高且污染严重,而混合动力技术可以弥补这方面的缺陷。文章以国内某SUV为例,对其改为混合动力后的驱动型式、动力总成参数的确定及性能预测等方面进行了研究并对仿真软件ADVISOR进行二次开发以便于四轮驱动的仿真分析。结果表明,与原车相比,混合动力SUV最高车速提高了32%,最大爬坡度提高了37%,油耗降低了29%,同时能在纯电动模式下以50km/h的速度行驶43.8km。指出改进后的混合动力SUV具有更好的动力性和经济性。

With the increase of domestic SUV population, increasing fuel consumption and serious pollution, hybrid technology can remedy the defect. Taking a domestic SUV for an example, the drive mode, power assembly parameter determination and performance prediction after modification of powertrain to hybrid drive is studied. And the simulation software ADVISOR is redeveloped for the simulation of a four-wheel drive hybrid vehicle. The results show that compared with the conventional vehicle, the hybrid SUV＇s maximum speed is improved 32% and grade-climbing ability is increased 37%, and fuel consumption is reduced 29%. Meanwhile in the mode of pure electric drive, it can run 43.8 kilometer at the speed of 50km/h. The result shows that the hybrid SUV has better driving performance and fuel economy, so the design requirement is met.
