Description

DCT离合器的接合点查找方法
技术领域
本发明涉及一种DCT离合器的接合点查找方法。
背景技术
在通过离合器接收发动机动力的变速器系统中，通常，以TS(Torque-Stroke；转矩-行程)特性曲线(以下称“TS曲线”)为基准来实现控制，所述TS曲线是表示离合器转矩对离合器位置(Stroke)的变化。因此，为了执行高可靠性的控制，需要对根据控制环境(离合器温度等)而变化的TS曲线进行学习。
在所述TS曲线中，接合点是离合盘(clutch plate)和发动机盘(engine plate)对接而向离合器传递发动机的动力的TS曲线的起始点，是具有重要意义的控制要素。
DCT(Dual Clutch Transmission；双离合变速器)主要对两个离合器中未驱动的离合器轴的接合点进行周期性学习，从而能够学习TS曲线。
换句话说，DCT具备能够通过致动器(actuator)而自动控制动力的离合器，在以干式型使用离合器的情况下，由于离合器的温度变化、磨损等，离合器的作为工作起始点的接合点发生变化，因此为了确保离合器的稳定工作性，需要对接合点进行恰当的学习。
就现有的接合点查找而言，通常在确认非驱动轴的空档状态后加载离合器，以此时形成的中立轴的速度变化值为基准实现查找。
但是，就双离合变速器(DCT)而言，具有如下优点：针对当前未驱动的离合器也对齿轮进行先连接，从而能够与下一变速进行对比。但是，存在如下缺点：在齿轮先连接的情况下，无法通过现有的方法查找接合点，如果持续其区间，则无法保证下一变速时的控制质量等等。
发明内容
要解决的问题
本发明涉及离合器的接合点查找方法，更为详细地，目的在于提供能够在非驱动轴齿轮连接的状态下查找接合点的离合器的接合点查找方法。
本发明的目的不限于以上所提及的目的，未提及的本发明的其他目的及优点通过以下说明能够得到理解，通过本发明的实施例能够更明确地理解。此外，能够了解到本发明的目的及优点通过权利要求书中所体现的装置及其组合能够实现。
解决问题的方案
用于达到这种目的的本发明提供一种DCT离合器的接合点查找方法，为离合器的接合点查找方法，包括如下步骤：(a)确认非驱动离合器及驱动离合器的接合点查找条件是否充分；(b)当在所述步骤(a)中查找条件充分时，向发动机加载非驱动离合器的位置值后，检测发动机的加速度值与驱动离合器的加速度值之间的差的绝对值超过基准值的查找点；以及(c)将与所述查找点相对应的非驱动离合器的位置决定为接合点。
在此，也可以是，在所述步骤(c)中，向与所述查找点相对应的非驱动离合器的位置，相加与发动机的转矩值相对应的接合点偏移补偿值，从而决定所述接合点。
此外，也可以是，所述步骤(a)的进入条件是，所述非驱动离合器为齿轮连接状态，并且所述驱动离合器为滑动控制状态。
在此，也可以是，在所述步骤(b)中，当虽然向发动机加载了非驱动离合器的位置值，但发动机的加速度值无变化时，停止接合点查找。
发明效果
根据如上所述的本发明，具有如下优点：在查找离合器接合点时，对齿轮未连接的非驱动轴也进行离合器接合点的查找，由此增加学习接合点的机会，能够提高TS曲线的可靠性。
由此，可得到如下效果：通过齿轮的先连接而变速时，只通过离合器转矩的切换就能够实施较快变速，从而能够发挥出DCT的优点。
附图说明
图1是用于说明本发明的实施例的DCT离合器的接合点查找方法的动作曲线。
图2是表示本发明的一实施例的DCT离合器的接合点查找方法的流程图。
具体实施方式
下文将参照附图对上文所述的目的、特征及优点进行详细说明，由此本发明所属技术领域内具有一般知识的人员能够轻易实施本发明的技术构思。在说明本发明时，如果判断为与本发明相关的公知技术的具体说明有可能会不必要地混淆本发明的主旨，则省略详细说明。以下，参照附图，对本发明的优选实施例进行详细说明。附图中相同的附图标记指代相同或类似的构成要素。
图1是用于说明本发明的实施例的DCT离合器的接合点查找方法的动作曲线。
通常在行驶状况下，离合器分为接收发动机动力的驱动离合器(离合器1)和与发动机动力切断的非驱动离合器(离合器2)。此时，非驱动离合器通过与预测的下一档位的先连接以基于车辆速度的齿轮比进行旋转。
本发明的目的在于提出如下新方法：为了对连接了齿轮的非驱动离合器轴进行接合点的查找，驱动离合器进行滑动(slip)控制，从而以与发动机转矩近似的转矩点启动齿轮时，向发动机施加非驱动离合器的转矩，由此将发动机和驱动轴的滑动变化量用作查找点。
换句话说，参照图1，示出有与空档状态(Neutral)的非驱动离合器(离合器2)连接齿轮(In gear)的同时，RPM增加的过程(I)。此外，由于正接收发动机的动力的驱动离合器(离合器1)处于滑动控制状态，因此可确认到发动机转矩(II)与驱动离合器转矩(III)具有近似的位置值。
在如此查找条件充分的状态下，换句话说，在驱动离合器为滑动控制状态，非驱动离合器为齿轮连接状态下，向发动机加载非驱动离合器的转矩(位置值)时，即如果向发动机加载从空档状态向齿轮连接状态转变的非驱动离合器的位置值，则能够确认到发动机的加速度值(IV)发生瞬间变动。并且，通过附图能够确认到利用如此发生的变动信息来能够查找非驱动离合器的接合点。
换句话说，可以将通过向发动机加载非驱动离合器的位置值所产生的发动机加速度值(IV)与滑动控制状态下维持一定水平的驱动离合器的加速度值(V)的差(|发动机加速度-离合器1加速度|)超过临界值(threshold)的瞬间(图1的竖直虚线)的非驱动离合器的位置(VI)决定为接合点。
此时，为了决定更准确的接合点，可优选构成为，相加与发动机的转矩(torque)相对应的适当的偏移(offset)补偿值(接合点-偏移；图1的水平虚线)而得到的位置被决定为接合点。
图2是表示本发明的一实施例的DCT离合器的接合点查找方法的流程图。
参照图2，可确认到本发明的一实施例的DCT离合器的接合点查找方法包括如下步骤：确认接合点查找条件是否充分S210；向发动机加载非驱动离合器的位置值S220；以及检测查找点S240等等。
确认接合点查找条件是否充分的步骤S210可包括如下两个详细过程：确认驱动离合器是滑动控制状态，确认非驱动离合器是齿轮连接状态。
当通过所述步骤210判断为接合点查找条件充分时，执行向发动机加载非驱动离合器的位置值的步骤S220。其与在前说明相同，向发动机加载从空档状态向齿轮连接状态转变的非驱动齿轮的位置值，从而使发动机的加速度值发生变化。
通过所述步骤S220向发动机加载非驱动离合器的位置值，由此，在发动机的加速度值发生变化的情况下S230，能够执行检测查找点的步骤S240。
查找点是发动机的加速度值与驱动离合器的加速度值之间的差的绝对值超过临界值(基准值)的起点。换句话说，就查找点而言，满足[|(发动机的加速度值)-(驱动离合器的加速度值)|＞临界值]的位置为查找点。
虽然可以将与通过查找点检测步骤S240所检测到的查找点相对应的非驱动离合器的位置决定为接合点，但是更为优选的是，通过在与检测到的查找点相对应的其非驱动离合器的位置，相加与发动机的转矩值相对应的接合点偏移补偿值(接合点-偏移)的补偿步骤S250，决定更准确的接合点S260。
在此，在通过所述的判断接合点查找条件是否充分的步骤S210判断出结果为其条件不充分的情况下，换句话说，驱动离合器不是滑动控制状态或非驱动离合器不是齿轮连接状态的情况下，如附图所示，可停止对非驱动离合器的接合点查找过程。
此外，也可以是，虽然向发动机加载了非驱动离合器的位置值S220，但发动机加速度值不发生变化的情况下S230，也不再进一步执行接合点查找过程。
即，虽然向发动机加载了非驱动离合器的位置值S220，但发动机的加速度值不发生变化的状态下，离合器的位置值达到设定的最大值的情况下，可能会发生锁定(interlock)状况，因此在本发明中，通过增加所述工序，能够实现接合点查找的停止。
如以上所说明那样，本发明提供一种离合器的接合点查找方法，在非驱动轴齿轮连接状态下滑动控制驱动轴时，通过加载非驱动轴的离合器的位置值来对查找点进行查找。
并且，由此能够提供如下各种效果：通过对非驱动离合器的接合点查找而增加学习接合点的机会，从而其结果，不仅能够提高TS曲线的可靠性，而且由此在通过齿轮的先连接实施的变速过程中，只通过离合器转矩的切换就能够实施较快变速，从而能够使DCT的优点最大化等等。
本发明所属技术领域内具有一般知识的人员在不脱离本发明的技术构思的范围内能够作出各种置换、变形及变更，因此所述的本发明不受所述实施例及附图的限定。
