Description

用于运行车辆制动装备的方法、控制器和车辆
技术领域
本发明涉及一种按照权利要求1的前序部分所述的用于运行车辆制动装备的方法。根据所述方法能够运行的车辆制动装备包括制动力放大器和电子的滑动调节装置，所述电子的滑动调节装置在所述制动力放大器失灵时能够被用作后备层级。
此外，本发明涉及一种控制器，所述控制器被设定用于实施按照本发明的方法。此外要求保护一种带有车辆制动装备和控制器的车辆，所述控制器被设定用于实施按照本发明的方法。
背景技术
上面所提到的类型的车辆制动装备示例性地由公开文献DE 10 2016 225 694 A1得知。该车辆制动装备不仅包括制动力放大器而且还包括滑动调节装置。所述滑动调节装置能够实现制动压力以轮个性化的方式分布到多个轮制动器上。在所述制动力放大器失灵时，所述滑动调节装置在此之外承担制动力放大。为此，借助于所述滑动调节装置的控制器检测主制动缸的压力腔室中的压力。当驾驶员操纵制动踏板时，主制动缸的压力腔室中的压力增大。
在失灵情况下、也就是说在没有通过所述制动力放大器进行制动力放大的情况下，最初通过驾驶员有待施加的力在操纵车辆制动装备时比正常情况下明显更高。此外，通常制动力支持只有当在主制动缸的压力腔室中构建一定的预压力时才能够通过所述滑动调节装置实现。
为了在失灵情况下减小用于激活所述滑动调节装置所必需的初始力并且为驾驶员提供更好的踏板感觉，在DE 10 2016 225 694 A1中提出了：在操控滑动调节装置的压力产生器时使用第一和第二输入信号。这两个输入信号——其中第一输入信号指明驾驶员的制动期望，并且第二制动信号代表所述主制动缸的压力腔室中的由驾驶员生成的制动压力——被再加工成分析信号，所述分析信号随后被相加成总和值，所述总和值对应于制动压力目标值。所述总和值又被转换成用于所述滑动调节装置的压力产生器的相应的操控信号。
基于上面所提到的现有技术应当提出一种用于运行车辆制动装备的方法，所述方法在制动力放大器失灵时即使驾驶员没有操纵制动踏板也能够通过滑动调节装置本身实现主制动缸的压力腔室中的压力构建。对于驾驶员操纵了制动踏板的情况而言，则应通过减小必需的初始力来实现踏板感觉的改善。
为了解决该任务提出了一种具有权利要求1的特征的方法。本发明的有利的改进方案能够从从属权利要求中得出。此外，提出了一种具有权利要求9的特征的控制器以及具有权利要求10的特征的车辆。
发明内容
提出了一种用于运行车辆制动装备的方法，所述车辆制动装备包括制动力放大器和电子的滑动调节装置。在所述方法中，滑动调节装置在所述制动力放大器失灵时被用作后备层级。按照本发明，在探测到所述制动力放大器失灵时求取加速踏板的位置，并且在所述加速踏板松开的前提下借助于所述滑动调节装置在所述车辆制动装备的主制动缸的压力腔室中构建预先给定的初始压力。以这种方式，即使驾驶员没有操纵制动踏板，也还是引起了车辆的减速。如果随后通过驾驶员操纵了制动踏板，则力耗费较小，因为已经借助于所述滑动调节装置生成了必需的初始力。因此作为结果实现了就驾驶员而言的踏板感觉的改善。
通过按照本发明仅仅在加速踏板松开的情况下、也就是说在加速踏板没有***纵的情况下进行主制动缸的压力腔室中的压力构建，能够在不涉及车辆的传动系的情况下执行所提出的方法。特别地，不必通过传动系来抑制加速以便实现所期望的减速。仅仅在车辆的制动***中进行该转换。
借助于所述滑动调节装置在主制动缸的压力腔室中所构建的初始压力能够例如是8巴（bar）。
优选地，借助于所述滑动调节装置从时间上控制构建到主制动缸的压力腔室中的初始压力上的压力构建。所述从时间上的控制能够实现：不依赖于主制动缸的压力腔室中的预压力地并且因此不依赖于车辆制动装备的制动踏板的位置地将压力构建到初始压力上。也就是说，不必首先在主制动缸的压力腔室中构建一定的预压力。
优选地，在执行所述方法时、也就是说在加速踏板松开的情况下求取车辆制动装备的制动踏板的位置。对于探测到对所述制动踏板的操纵的情况而言，在主制动缸的压力腔室中进行压力构建时能够考虑在主制动缸的压力腔室中通过操纵所述制动踏板所生成的预压力。所述压力构建而后优选与所生成的预压力成比例地进行，更确切地说以系数x、例如以系数3来放大。
此外优选地，在探测到对所述制动踏板的操纵时，借助于所述滑动调节装置在主制动缸的压力腔室中构建压力，所述压力对应于以系数x放大的预压力加上初始压力。因此，主制动缸的压力腔室中的最小压力对应于借助于所述滑动调节装置所生成的初始压力。
为了求取制动踏板的位置，优选测量主制动缸的压力腔室中的压力。相应的传感器装置通常已经存在，从而能够在此被采用。更确切地说，必须首先生成一定的预压力，由此借助于所述传感器装置来检测所述预压力。因为按照本发明不依赖于对所述制动踏板的操纵地实现将压力构建到初始压力上，所以是在构建一定的预压力的同时探测所述制动踏板的操纵还是从构建了一定的预压力起才探测所述制动踏板的操纵并不重要。
在本发明的改进方案中提出了：例如在使用按照开头所提到的现有技术的二进制信息的情况下实现另一后备层级。通过附加的后备层级能够实现对车辆制动装备的制动特性的进一步改善。
有利的是，在将压力构建到主制动缸的压力腔室中的初始压力上之后重新求取所述加速踏板的位置。如果在将压力构建到初始压力上之后探测到对所述加速踏板的操纵，则降低主制动缸的压力腔室中的压力。所述压力降低应当能够在之前所引起的车辆减速之后实现车辆的重新加速。在此，优选借助于所述滑动调节装置从时间上控制所述压力降低。
优选地，借助于所述滑动调节装置的控制器探测所述制动力放大器的失灵，所述控制器为此以数据传输的方式、例如通过CAN总线与所述制动力放大器连接。所述失灵而后能够通过所述制动力放大器的相应的消息被传达给所述控制器。如果所述制动力放大器以不再能够发送相应的消息这样的方式失灵，则能够识别到通信故障上的失灵。如果所述制动力放大器是负压制动力放大器，则也能够通过分析负压传感器来探测失灵。
因为优选地在执行按照本发明的方法时使用一种控制器，所以此外提出了一种控制器，所述控制器被设定用于实施按照本发明的方法。该装置例如能够包括计算机程序的加载，所述计算机程序包含程序代码，当所述计算机程序在所述控制器上运行时，所述程序代码实施所述方法。
此外，提出一种带有车辆制动装备和控制器的车辆，其中所述控制器被设定用于实施按照本发明的方法。之前结合所述方法所说明的优点也能够利用所述车辆来实现。特别地，在所述制动力放大器故障时能够提高就车辆的驾驶员而言的制动舒适度。
附图说明
本发明在下文中借助于附图被更详细地解读。其中：
图1示出了用于图解地展示按照本发明的方法的典型的过程的流程图；
图2示出了按照现有技术和按照本发明的第一实施方式的关于加速踏板位置或者说制动踏板位置的减速特性和加速特性的示意性的示图；并且
图3示出了按照现有技术以及按照本发明的第一和第二实施方式的关于加速踏板位置或者说制动踏板位置的减速特性和加速特性的示意性的示图。
具体实施方式
借助于在图1中所示出的流程图首先说明按照本发明的方法的典型的方法过程。
从状态10开始——在所述状态10中车辆制动装备仍然无故障地工作——在步骤20中发现所述车辆制动装备的制动力放大器的失灵。随着失灵的出现，在下一步骤30中求取加速踏板的位置，以便检验：是驾驶员操纵了所述加速踏板还是所述加速踏板是松开的。因为在操纵所述加速踏板时车辆被加速，从而使得车辆的减速仅仅在涉及传动系的情况下才能够实现。然而这在此应当被避免，从而在操纵所述加速踏板时在步骤40中没有压力会借助于滑动调节装置在主制动缸的压力腔室中被构建。如果在重新的检验50时确定了现在加速踏板是松开的，则在步骤60中首先求取制动踏板的位置。如果由于主制动缸的压力腔室中的不足的预压力而假设所述制动踏板是松开的，则在步骤70.1中在主制动缸的压力腔室中从时间上受控地将压力构建到预先给定的初始压力上、例如构建到8巴上。如果构建好所述初始压力或者说达到状态80，则在步骤90中重新求取制动踏板的位置，以便检验：驾驶员现在是否已经操纵所述制动踏板。如果是这种情况，则在步骤70.2中借助于所述滑动调节装置在主制动缸的压力腔室中生成另一压力构建，所述另一压力构建对应于由驾驶员通过操纵所述制动踏板而引起的预压力乘以系数x加上初始压力。如果在步骤100中所执行的对制动踏板位置的重新检验得出了所述制动踏板是松开的，则将所述压力腔室中的压力下降到初始压力上，从而重新到达状态80。随后重复步骤30，以便确定是否重新操纵所述加速踏板。如果是这种情况，则在步骤40中不仅不在所述压力腔室中构建压力，而且还主动地降低压力，以便能够实现所述车辆的加速。
借助于按照本发明的方法能够实现车辆的制动特性的积极的变化，所述变化表现在就驾驶员而言提高了的制动舒适度中。在此，所述车辆的加速特性保持不变。
如示例性地在图2中所示出的那样，所述车辆在操纵所述加速踏板时与所述加速踏板的位置成比例地被加速（参见图2的右半部分上的曲线图1、2）。如果探测到所述制动力放大器的失灵，则首先检验：是所述加速踏板***纵了还是所述加速踏板松开了。如果是后者这种情况，则能够根据所提的按照本发明的方法执行制动力放大。为此，首先借助于所述滑动调节装置促使压力构建到初始力上，也就是说不依赖于所述制动踏板是否同时***纵。所述初始压力被选择得如此高，以引起所述车辆的明显的减速（参见图2的中间的曲线图2的垂直的走向）。如果所述制动踏板被驾驶员操纵，则这逐渐地导致了所述主制动缸的压力缸中的另一压力构建，然而所述另一压力构建相比于已经构建的初始压力较小并且因此几乎不对所述车辆的减速产生影响（参见图2的左半部分中的曲线图2的略微下降的走向）。只有当到达确定的预压力时，所述另一压力构建才被检测并且借助于所述滑动调节装置以确定的系数x被放大（参见图2的左半部分中的曲线图2的陡峭地下降的走向）。
借助于曲线图1示出了现有技术。在此，车辆的减速依赖于通过驾驶员进行的对制动踏板的操纵。也就是说，驾驶员必须操纵制动踏板并且必须首先在主制动缸的压力腔室中实现一定的预压力，直到借助于所述滑动调节装置能够实现压力放大。
由图3能够得出本发明的一种改进方案。在图3中，曲线图3表示在使用二进制信息的情况下所实现的另一后备层级。在此，这能够例如是与位移相关的信息，通过所述与位移相关的信息能够推导出制动踏板位置。借助于所述制动力放大器的位移传感器能够执行必需的测量。然而这以下述情况为前提：失灵没有已经导致所述制动力放大器的完全故障。
