Continuous Power Shift Control Strategy of Continuously Variable Transmission System with Reflux Power
摘要
Abstract
In order to avoid power loss of continuously variable transmission system with reflux power and reduce vehicle jerk,a continuous power shift control strategy of continuously variable transmission system with reflux power was put forward.Aimed at shifting process,transmission efficiency and the opposite direction of continuously variable unit had impact on transmission output torque,a dynamics model of clutch engagement and disengagement course was established, and the range of clutch torque change ratio was calculated. Taking MATLAB/Simulink as the platform,simulation study of shifting process was carried out, the results indicate that jerk is less than 5m/s^3 by adopting continuous power shift control strategy of continuously variable transmission system with reflux power.关键词
