Description

避免对机动车驱动系的混合动力模块中的分离离合器进行危及安全性的操纵的方法
技术领域
本发明涉及一种根据权利要求1前序部分的、用于避免对在机动车驱动系的混合动力模块中的分离离合器进行危及安全性的操纵的方法。在这样的方法中，混合动力模块在内燃机和变速器之间起作用并且具有电驱动装置、分离离合器和自由轮，其中，分离离合器用于通过由与用于纯电动行驶的电驱动装置或者驱动系的力锁合连接传递由电驱动装置或者驱动系所提供的转矩来起动内燃机。
背景技术
由DE102012206680A1已知用于机动车的动力系统的混合动力模块。该混合动力模块布置在内燃机和变速器之间并且具有电驱动装置、分离离合器和自由轮，其中，分离离合器和自由轮相对于彼此平行地分别设置用于从内燃机向变速器的方向的转矩传递。自由轮将来自内燃机的转矩向变速器方向传递并且在转矩反向地定向的情况下打开，使得机动车能选择性地由内燃机或者电驱动装置或者组合地同时通过两者来驱动。在此，分离离合器具有这样的任务：通过由内燃机和电驱动装置或者说驱动系的力锁合的连接传递电驱动装置或者说驱动系所提供的转矩来起动内燃机或者使内燃机与驱动系脱耦，以便纯电动地运行机动车或者在混合动力行驶运行中传递内燃机牵引力矩和内燃机滑移力矩。
因此，从电动到混合动力的行驶运行的更换需要分离离合器的闭合，以便起动内燃机。尤其在通过进行转动的驱动系的动能起动或者说再起动时，由于分离离合器的闭合和静止的内燃机的与之相联系的加速而导致相应的制动力矩。在功能安全性的意义中，在电动的、电子的或者可编程的电分离系统发生功能性故障的情况下可以想象车辆和车辆乘客的危险情况。特别在分离离合器系统无意的闭合的情况下，例如在电动的曲线行驶期间，危险可能性特别高。为了在故障情况下及时地作出反应并且因此能够避免分离离合器的对安全性至关重要的闭合，在分离离合器系统中在离合器位置“打开”的方向上需要一段安全距离，以便能够满足为故障识别和引入适当的补救措施所需要的时间段。在安全距离固定地设定的情况下，尽管如此，由于离合器操纵系统出现的故障可能发生分离离合器的无意的闭合，这可能引起机动车的危及安全性的情形。
发明内容
因此，本发明的任务在于，说明一种用于避免对在机动车驱动系的混合动力模块中的分离离合器进行危及安全性的操纵的方法，在该方法中，离合器操纵系统的故障被补偿。
根据本发明，该任务由此解决：基于机动车的环境条件和/或车辆边界条件调节设定打开的分离离合器的要维持的安全距离。在此，打开的离合器的安全距离应理解为在考虑分离离合器打开时的分离行程的情况下的摩擦衬片的间距。通过在选择安全距离时考虑环境条件调节设定足够大的安全距离，在所述安全距离中，在离合器操纵系统故障的情况下也可靠地禁止分离离合器的无意闭合。在此，机动车系统不必总体在过安全(übersicher)的范围内运行，所述过安全的范围满足所有想得到的情况，但是，尽管如此，它呈现出尽可能高的系统动态性、系统可用性和系统安全性。
有利地，基于与机动车的环境条件和/或车辆边界条件相关的临界的干扰力矩来调节设定安全距离。在此，所述考虑基于，在环境条件差的情况下安全距离由于小的要容忍的干扰力矩而必须较大，反之，在环境条件较好的情况下，安全距离由于较大的可容忍的干扰力矩而设置得较小。考虑，在技术性能方面也可能出现故障，其中，必须确保，安全距离总是考虑离合器的充分打开的位置。
在一种构型中，安全距离被限定为在从临界的干扰力矩的位置出发的离合器特征曲线上的常数。通过打开的分离离合器自临界的干扰力矩的恒定的距离确保，在临界的行驶状况的情况下，由于技术性能的故障，离合器不会无意地转换到闭合的状态中。通过包括离合器特征曲线进行在故障情况下出现的离合器动态的考虑，这改进了要调节设定的安全距离的准确性。
在一种变型中，基于车辆车轮的摩擦系数确定临界的干扰力矩。尤其在被雨淋湿的车道中或者在冰面光滑的情况下摩擦系数改变，使得基于不同的摩擦系数改变干扰力矩，以便禁止对分离离合器的危急安全性的操纵，因为出现轮胎到车道上的有差异的力传递。
在一种拓展方案中，摩擦系数对于机动车的外部温度的一预先给定的范围而言构造为常数。因此，摩擦系数例如可在外部温度<3℃和外部温度>3℃时确定，以便对在轮胎和车道之间的摩擦传递进行分类。
在另一实施方式中，基于机动车的横向加速度确定临界的干扰力矩。在此，尤其在以恒定的行驶速度的曲线行驶的情况下考虑可容忍的干扰力矩与参量、即道路附着系数、挡位传动比和行驶速度或者说与其相关的横向加速度的相关性，以确保车辆安全性。
在一种变型中，基于分离离合器的歧点(Tastpunkt)可变地调节设定安全距离。歧点值应理解为离合器的如下分离行程，在所述分离行程中离合器开始接触配合(greifen)，并且转矩从内燃机传递到驱动系上。因为该歧点依赖于驱动系的结构性的构造并且遭受老化效应，所以它必须持续地重新估算。
在一种构型中，基于分离离合器的歧点的最后已知的位置调节设定安全距离，其中，考虑歧点的温度相关性。通过基于所述歧点对安全距离进行调节设定来确保，在离合器打开的位置中总是存在足够的距离，所述距离在离合器操纵系统的功能有缺陷时防止分离离合器无意地闭合。
在一种构型中，通过机动车的通信线提供关于环境条件和/或车辆边界条件的信息。由此也将存在于机动车中的传感器所提供的数据用于禁止对分离离合器的危急安全性的操纵。
附图说明
本发明允许多种实施方式。根据在附图中所示出的图详细解释其中之一。
附图示出：
图1具有混合动力模块的机动车的驱动系的示意性示图，
图2临界的干扰力矩作为摩擦附着力、挡位和车辆速度的函数的概况。
图3根据本发明的方法的第一实施例，
图4根据本发明的方法的第二实施例。
具体实施方式
图1示意性地示出机动车的动力系统，其具有内燃机1、附接在内燃机1曲轴2上的振动减振器3、具有自由轮5和分离离合器6的混合动力模块4以及具有电驱动装置的转子7和定子8、变速器9、差速器10和未以细节示出的车轮。在内燃机1和变速器9之间设置有两个并行的转矩传递线路。第一转矩传递线路包括分离离合器6，第二转矩传递线路包括自由轮5。自由轮5将转矩从内燃机1传递到变速器9上并且在转矩流方向从变速器9到内燃机1的情况下打开。在分离离合器6闭合的情况下转矩能从变速器9向内燃机1的方向传递。这尤其涉及通过电动行驶起动内燃机1以及在电池满的情况下传递滑移力矩。
在动力系统的内燃机式的运行中，分离离合器6保持闭合，使得它根据其附有的转矩传递容量分别按份额地与自由轮5一起传递可被内燃机1传递的力矩。分离离合器6的功能由与上一级的车辆控制器12连接的控制器11控制。在此，控制器11和车辆控制器12通过车辆通信线、优选CAN总线15相互连接并且与传感器13和驾驶员辅助系统14连接。
在图2中示出临界的干扰力矩作为摩擦系数、挡位以及车辆速度的函数的概况。如从图2可推断出，在第二挡位中以30km/h在雪地或者说冰面光滑的车道(假设摩擦系数μ＝0.3)的情况下行驶曲线时，>55nm的干扰力矩已经能够导致在轮胎和驱动轴旁的车道之间可能的危及安全性的附着破坏(Haftabriss)。
在因下雨而淋湿的车道中，摩擦系数μ提高到大约0.7，这允许直至大约150nm的可容忍的干扰力矩。通过考虑在故障情况下出现的离合器动态，可基于需要的故障公差时间限定需要的要维持的安全性距离。即，在环境条件坏的情况下，安全性距离由于较小的可容忍的干扰力矩而必须变得较大。从该事实得出依赖于环境条件的不同的安全性距离，所述安全性距离一方面有助于功能安全性而且有助于系统的可能的可用性。
为了设定安全性距离，确定临界的干扰力矩Mkrit，这如下求取。
其中，μ代表摩擦系数且v2/r代表横向加速度。也可以基于歧点T的最后已知的位置求取所求取的临界的干扰力矩Mkrit的所属的位置。在此，考虑或者说附加地维持歧点T例如由于温度影响的变动。现在，在临界的干扰力矩Mkrit的这样计算出的位置上可限定必需的位置“可靠地打开”，在内燃机1脱耦的情况下必须操纵并且保持分离离合器6直至所述必需的位置。
通过离合器特征曲线的知识，可基于传感器13所提供的信息、例如在外部温度<3℃的情况下可能的滑动危险和/或所测量的横向加速度而与安全距离s的依赖于整个系统的故障公差时间组合地限定存在的驾驶员辅助系统14。
在图3中示出离合器特征曲线，在该特征曲线中示出关于分离离合器6的分离行程的要传递的转矩。在图3中所示出的情形中，从30km/h的车辆速度和μ＝0.7的摩擦系数出发，这与湿的车道相似。在这种情形中，存在155nm的容许的干扰力矩Mkrit，因此不出现轮胎与车道的附着破坏。假设100ms的故障公差时间，在所述故障公差时间内允许出现的故障。此外，假设在故障情况下30mm/s的平均的致动器动力，分离离合器6的致动器以所述致动器动力向闭合方向运动。
从该假设得出s＝v*t＝3mm的必需的安全性距离s。该安全性距离s作为常数加到相应于临界的干扰力矩Mkrit的分离行程上，所述干扰力矩基于环境条件而改变，附加到离合器的分离行程上。通过打开的分离离合器6现在占用的该安全性距离s，在离合器操纵系统故障的情况下分离离合器6也在“可靠地打开”的位置中，在该位置中可靠地禁止分离离合器6的无意的闭合。在此，离合器操纵系统的歧点T可靠地位于所求取的安全性距离s以内，使得由此推测不出现离合器的闭合。
在图4中所示出的第二种情形中，根据离合器特征曲线推测：机动车具有30km/h的速度且摩擦系数μ＝0.2，这与雪覆盖和冰覆盖的车道相提并论。容许的临界的干扰力矩MKrit被限制在25nm，在所述临界的干扰力矩的情况下车轮与车道的附着破坏不出现。假设故障公差时间100ms，在该故障公差时间以内允许控制器11的故障，而假设在故障情况下用于使分离离合器6运动的平均的致动器动力为30mm/s。
也在这种给定的条件下确定s＝v*t＝3mm的必需的安全性距离s。在转矩低的情况下，基于机动车的如摩擦系数和外部温度这样的环境条件而改变的临界的干扰力矩MKrit位于此。在这里，在分离离合器6的相应于临界的干扰力矩MKrit的分离行程上附加3mm的安全性距离s，以便因此确保分离离合器6的“可靠地打开”位置。在这种给定条件下，分离离合器6的歧点T可靠地位于由安全性距离s撑开的分离行程以内。然而，在一替代方案中，也可以基于歧点T可变地限定安全性距离s。
