Description

用于避免对机动车的传动系的混合动力模块中的分离离合器进行危及安全的操作的方法
技术领域
本发明涉及一种用于避免对机动车的传动系的混合动力模块中的分离离合器进行危及安全的操作的方法，其中，混合动力模块在内燃机与变速器之间起作用并且具有电驱动器、分离离合器和超越离合器，而且分离离合器被用于以通过与电驱动器或者传动系的力锁合的连接来传递由电驱动器或者传动系提供的转矩的方式启动内燃机，或者被用于为了纯电动行驶而将内燃机从传动系上脱开。
背景技术
由文献DE102012206680A1公知了一种用于车辆的驱动系的混合动力模块。混合动力模块布置在内燃机与变速器之间并且具有电驱动器、分离离合器和超越离合器，其中，分离离合器和超越离合器彼此并联地设置，分别用以从内燃机到变速器的转矩传递。该超越离合器将转矩从内燃机到变速器传递并且在转矩指向相反的情况下打开，从而使车辆能够可选地要么通过内燃机来驱动，要么通过电动机来驱动，要么同时通过两者相结合地来驱动。分离离合器在此具有下述任务，即，以通过内燃机与电驱动器或者传动系的力锁合的连接来传递由电驱动器或者传动系提供的转矩的方式启动内燃机，或者将内燃机从传动系上脱开，以便以纯电动的方式运行机动车或者在混合动力的行驶运行下传递内燃机的牵引力矩和推车力矩。
因此，从电动行驶运行切换到混合动力行驶运行需要闭合分离离合器，以便启动内燃机。特别是在通过转动的传动系的动能进行启动或者再启动时，由于闭合分离离合器以及与之相关地对内燃机的加速而产生相应的制动力矩，该制动力矩还被称作干扰力矩。该干扰力矩在一定的环境影响下可能导致机动车的危及安全的情况发生。
发明内容
因此，本发明的任务在于提出一种用于避免对机动车的混合动力模块中的分离离合器进行危及安全的操作的方法。
根据本发明，该任务通过如下方式解决，即，依赖于机动车的环境条件和/或车辆边界条件调整分离离合器的临界的干扰力矩，用以调整出对打开的分离离合器的要保留的安全间距。打开的离合器的安全间距应当理解为在考虑打开的分离离合器时的分离距离的情况下的摩擦片的间距。在不良的环境条件下，由于较小的、要容忍的干扰力矩而将安全间距调整得较大，而在良好的环境条件下，由于较大的、能容忍的干扰力矩而将安全间距调整得较小。基于干扰力矩与安全间距之间的间接联系，在机动车行驶运行的任何情况下都确保了尽可能高的系统动力学性能和安全性。在此，车辆系统不必通常在超安全区域运行，该超安全区域涵盖了所有能想到的情况，然而尽管如此还是提供了尽可能最高的系统动力性能、系统可供性和系统安全性。
有利地，临界的干扰力矩依赖于车轮的摩擦系数来确定。特别是在被雨淋湿的道路和结冰道路上，摩擦系数发生变化，从而使干扰力矩依赖于不同的摩擦值发生变化，以便禁止对分离离合器的危及安全的操作，这是因为，在道路上出现了轮胎的差别化的力传递。
在一个设计方案中，针对机动车的外部温度的范围来说，摩擦系数为恒定值。因而可以例如在小于3℃的外部温度下以及大于3℃的外部温度下确定摩擦系数，以便对轮胎与道路之间的力传递进行分级。
在一个变型方案中，临界的干扰力矩依赖于机动车的横向加速度来确定。在此，特别是在以恒定的行驶速度进行曲线行驶时，考虑能容忍的干扰力矩与道路附着系数、变速传动比和行驶速度或者与此相联系的横向加速度的大小的依赖性，以便确保车辆安全性。
在一个改进方案中，在超过临界的干扰力矩时，通过预定的转矩导入用于降低临界的干扰力矩的行驶动力学措施，以便确保车辆安全性。对于此种行驶动力学措施，可以例如挂入更高挡，或者在启动内燃机之前将内燃机与传动系分离，或者避免在低过限定的横向加速度界限之后启动内燃机。
在一个设计方案中，关于环境条件和/或车辆边界条件的信息经由机动车的通信线路来提供。由此，那些由本身位于机动车中的传感器提供的数据也被用于禁止对分离离合器进行危及安全的操作。
有利地，在获知离合器特征曲线的情况下通过观察关于环境条件和/或车辆边界条件的信息来调整出打开的分离离合器的安全间距。通过引入离合器特征曲线来实现考虑在有误差情况下出现的离合器动力学特性，这改善了要调整出的安全间距的精确性。
附图说明
本发明允许了多种多样的实施方式。借助在附图中示出的图示进一步阐明其中一个实施方式。在附图中：
图1示出带有混合动力模块的机动车驱动系的示意性图示；
图2示出作为静摩擦力、挡和车速的函数的临界的干扰力矩的概览图。
具体实施方式
图1示意性示出了带有内燃机1的机动车驱动系、连接在内燃机1的曲轴2上的减振器3、带有超越离合器5和分离离合器6以及带有电驱动器的定子7和转子8的混合动力模块4、变速器9、差速器10和未详细示出的车轮。在内燃机1与变速器9之间布置有两个并联的转矩传递系。第一转矩传递系包含分离离合器6，而第二转矩传递系包含超越离合器5。超越离合器5在从内燃机1到变速器9的转矩传递时进行传递并且在从变速器9到内燃机1的转矩流向的情况下打开。在离合器闭合的情况下，能传递从变速器9到内燃机1的转矩。这特别是涉及在电动行驶中启动内燃机1以及在电池充满的情况下传递推车力矩。在驱动系的以内燃机驱动的运行中，分离离合器6保持闭合，从而分离离合器根据其带有的转矩传递能力分别按比例分配的方式与超越离合器一起传递能由内燃机1传递的转矩。分离离合器6的功能在此通过控制器11来控制，该控制器与上级的车辆控制器12连接。控制器11和车辆控制器12在此通过车辆通信线路，优选是CAN总线15，彼此连接并且与传感器13和驾驶辅助系统14连接。
在图2中示出了临界的干扰力矩作为静摩擦力、挡和车速的函数的概览图。如从图2可以看出：在雪地或者结冰的道路上(假设摩擦系数μ＝0.3)在以30km/h且第二挡的行驶曲线的情况下，大于55Nm的干扰力矩已经导致在驱动轴上出现可能的危及安全的轮胎与道路之间的附着力中断。为了禁止机动车的这种临界状况，控制器11以如下方式驱控分离离合器6，即，依赖于环境条件或者由车辆边界条件来确定打开的离合器的预定的安全间距。为了调整出该安全间距而确定临界的干扰力矩(M临界)，这以如下方式来获知：
其中，
μ是摩擦系数
ν2/r是横向加速度
依赖于在小于3℃的外部温度下和/或在通过驾驶辅助系统14测得的横向加速度下附加地检测的信息，例如可能的打滑风险，来调整临界的干扰力矩M临界，相当于依赖于该环境条件和/或该车辆边界条件来调整。如果上级的车辆控制器12的预定的转矩期望高于获知的临界的干扰力矩M临界，就采取使行驶运行稳定化的措施，例如挂入到更高的挡或者与内燃机1的传动系分离，或者不启动内燃机1直至低过要限定的横向加速度界限之后。因而禁止了危及安全的行驶状态。同样，对于直线驾驶的情况，亦即几乎没有横向力的行驶，依赖于温度来实施内燃机的启动，以便避免危及安全的车轮打滑。没有横向力影响的情况下，临界的干扰力矩M临界设计为摩擦系数或者所挂入的挡的函数，并且几乎不依赖于行驶速度地设计为水平的线(图2)。
在被雨淋湿的道路上，摩擦系数μ提高到大约0.7，这允许了直至大约150Nm的能容忍的干扰力矩。通过考虑在误差情况下出现的离合器动力学性能，可以依赖于所需要的误差容忍时间限定出必需的、要保留的打开的分离离合器6的安全间距。对于更差的环境条件，由于更小的能容忍的干扰力矩而安全间距因此更大。由于该事实，得出了依赖于环境条件的、不同的安全间距，其首先用于系统的功能安全性以及可能的系统可用性。通过获知离合器特征曲线，可以依赖于在小于3℃的外部温度和/或由驾驶辅助系统测得的横向加速度的情况下下进一步检测到的信息(例如可能的打滑温度)，可以与依赖于整个系统的误差容忍时间相结合地来限定安全间距。
