湿式DCT离合器半结合点自学习控制策略研究

Research of Clutch Kiss-point a Daption Control Strategy for Wet DCT

文章介绍了一种湿式双离合器自动变速箱离合器半结合点自学习控制策略。通过变速箱实际工作时,离合器压力控制阀的压力和电流特性在半结合点附近的非线性关系,以离合器压力斜率为判断依据,找到准确的半结合点,并通过整车测试验证,证明了该策略的快速、准确和稳定的特点。

This document introduces a kind of wet dual clutch automatic transmission kiss-point adaption control strategy.The pressure and current characteristic curves of clutch pressure control valve is nonlinear relationship near the kiss-point during the gearbox is normally working,according to the clutch pressure gradient,find the correct kiss-point finally,the strategy has already tested on the vehicle,and proved the quickness,accuracy and stability of the strategy.
