基于车速跟踪的商用车燃油经济性建模与仿真
Modeling and Simulation of Commercial Vehicle Fuel Economy Based on Vehicle Speed Tracking
摘要
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 mod-eling method was proposed based on longitudinal vehicle speed tracking.On the premise of the estab-lishment of vehicle longitudinal dynamics model,driving intention model,engine and transmission sys-tem 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 re-sults 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 ve-hicles with various powertrain configuration can be carried out conveniently and quickly.关键词
