新型电控液驱车辆燃油经济性计算与分析

Fuel Economic Analysis for a New Vehicle with Electronic Control and Hydrostatic Transmission

利用系统辨识的原理建立发动机数学模型,建立了电控液驱车辆不同行驶状态下的燃油经济性计算模型。采用基于MATLAB/Simulink语言编写计算程序进行仿真分析,通过实例计算得出了电控液驱车辆不同行驶工况下的燃油消耗指标,与传统车辆进行比较,电控液驱车辆具有明显的节能效果。

By using the identification principle, the engine fuel consumption models were established. Then, the fuel economy calculations with various operating models were carried out. The simulation and calculation programs including those of the engine fuel consumption model and the various driving models were written in MATLAB/Simulink. An index of fuel consumption has been obtained by calculating with the vehicle of hydrostatic transmission in different driving models. Compared with that of traditional transmission the effect for saving fuel has been proved good.
