装备单环路系统的整车行驶动力学研究
Research on Driving Dynamics for Vehicles Equipped With a Single Loop Systems
摘要
Abstract
Power split structure scheme of the single loop system was given,bond graph model of the vehicle which equipped with XP and PX type power split continuously variable transmission was established,and the state equation of the system was deduced.Taking MATLAB/Simulink as a platG form,the simulation model of the vehicle was established.Given UDDS driving cycles,using the best fuel economy control strategy for the economics selection of the XP type and PX type power split sinG gle loop system,the XP type single loop system has better economy.When the driving cycle acceleraG tion rapidly changing,the engine torque and the single loop system transmission ratio has abrupt variaG tion,which leads to the vibration of the basic component of the differential gear train.关键词
