Modeling and Simulation of Commercial Vehicle Fuel Economy Based on Vehicle Speed Tracking

Abstract

Abstract:

Most of the fuel economy simulation models can only calculate fuel consumption of the vehicle in modal cycles.To solve the problem,a new method for commercial vehicle fuel economy modeling method was proposed based on longitudinal vehicle speed tracking.On the premise of the establishment of vehicle longitudinal dynamics model,driving intention model,engine and transmission system model,a commercial vehicle fuel economy simulation model was built with MATLAB/Simulink.Taking a bus as an example,a comparison was made between vehicle test and model simulation,the results of which show that:the simulation model can follow any driving cycle of commercial vehicle very well,and calculate the commercial vehicle fuel consumption in the driving cycle accurately.By changing the vehicle related parameters in the simulation model, simulation of fuel economy for commercial vehicles with various powertrain configuration can be carried out conveniently and quickly.

Key words: commercial vehicle, fuel economy, vehicle speed tracking, simulation model

摘要：

针对燃油经济性仿真模型仅能计算车辆在模态工况下的燃油消耗量的问题，提出了一种基于车速跟踪的燃油经济性仿真模型的建模方法。在建立车辆纵向动力学模型、驾驶意图模型和发动机与传动系统模型的基础上，利用MATLAB/Simulink搭建了商用车燃油经济性仿真模型，并以某客车为例进行了试验与仿真对比。对比结果表明：所建模型能对商用车的任意行驶工况进行较好的车速跟踪,并能对商用车在该行驶工况下的燃油消耗量进行较为准确的仿真计算。通过更改仿真模型中的相关车辆参数，可以方便快速地进行不同动力总成配置的商用车的燃油经济性仿真计算。
