基于分段线性控制策略的回流式无级变速器起步仿真研究

Abstract

The dynamical model is established based on the analysis for starting process of continuously variable transmission system with reflux power.To achieve the goal of constant engine speed starting control,the target control table on the changing rate of electronic throttle opening and engagement pressure of the clutch are obtained,which will change with the objective oil pedal opening. Taking Matlab/Simulink as the platform,the starting process of continuously variable transmission system with reflux power is analyzed.The results indicate that jerk is less than 10m/s3by adopting piecewise linear control strategy of the changing rate of electronic throttle opening.
