Abstract

为了检查助力车辆制动设备，本发明提出，两次在压力形成的意义上移动助力制动压力产生器（1）的活塞（3）并且在此之间使其返回移动优选更长的行程。如果在第二次移动时的活塞行程延长，那么由于制动液储存容器（16）中太低的制动液水平而可以推断出在所述助力制动压力产生器（1）的缸（3）中存在空气。

Description

用于检查助力车辆制动设备的方法
技术领域
本发明涉及一种具有权利要求1的前序部分的特征的用于检查助力车辆制动设备的方法。
背景技术
一种助力车辆制动设备从国际专利申请WO 2012/150 120 A1中已知。已知的车辆制动设备具有带有活塞-缸单元的助力制动压力产生器，所述活塞-缸单元的活塞为了产生制动压力而能够借助于电动马达通过螺纹驱动装置在缸中移动。
如果空气进入到这样的助力车辆制动设备的制动液中，这对于车辆驾驶员来说是不能得知的，因为助力制动压力产生器的活塞的移动行程（Verschiebeweg）在没有对例如脚制动踏板或者手制动杆的反作用的情况下或者在没有其它对驾驶员来说能够识别的影响下延长。
发明内容
根据本发明的具有权利要求1的特征的方法被设置用于检查具有带有活塞-缸单元的助力制动压力产生器的助力车辆制动设备，所述活塞-缸单元的缸与尤其无压力的制动液储存容器连通。为了产生制动压力，活塞-缸单元的、也能够理解为助力制动压力产生器的活塞的活塞能够借助于电动马达通过螺旋齿轮传动机构在缸中移动，其中反过来缸也能够在活塞上移动。螺旋齿轮传动机构比如是滚珠丝杠传动装置。也能够取代螺旋齿轮传动机构而使用其它的旋转-平移-转换传动机构。在电动马达与螺旋齿轮传动机构之间能够布置机械的减速传动机构。电动马达、螺旋齿轮传动机构以及可能的减速传动机构是助力制动压力产生器的组成部分。
助力制动压力产生器的缸通过第一和/或第二制动液管路与制动液储存容器连通。第一制动液管路能够通过缸中的活塞在制动压力形成的意义上离开基础位置移动这种方式来闭锁。第二制动液管路具有能够朝缸的方向通流的止回阀。
助力制动压力产生器的缸通过一个或多个隔离阀（Trennventil）与助力车辆制动设备的其他部件、特别是与液压的车轮制动器相连接，并且能够通过所述一个或多个隔离阀的关闭在液压方面与助力车辆制动设备的其他部件分离。压力传感器被连接到助力制动压力产生器的缸上 。
为了根据本发明检查助力车辆制动设备而即将关闭或关闭一个或多个隔离阀并且闭锁第一制动液管路，使得制动液积被围在助力制动压力产生器的缸中。两次制动压力形成的意义上在缸中移动助力制动压力产生器的活塞并且在此期间将该活塞返回移动不一样的行程，使得活塞在压力形成的意义上进行的第一次移动开始时在缸中具有与在压力形成的意义上进行的第二次移动开始时不同的位置。尤其在两次在制动压力形成的意义上进行的移动之间使所述活塞在所述缸中返回移动，返回移动的幅度大于在制动压力形成的意义上在第一次移动时已经使其移动的幅度。
在活塞移动的期间或结束时，测量助力制动压力产生器的缸中的压力。如果出现与常见的、所计算的或可预料的压力或压力变化曲线的偏差，则可以推断出助力车辆制动设备中的误差。在活塞在缸中的位置或者移动方面对助力制动压力产生器的缸中的压力进行评估。
如果比如在为了产生特定的压力而在压力形成的意义上使该活塞在其第二次移动时的移动行程比在其第一次移动时长，那么在返回移动时可能空气进入到助力制动压力产生器的缸中，这可以推断出制动液储存容器中的太低的制动液水平。没有排除其他的误差或原因。
如果在助力制动压力产生器的活塞的两次在制动压力形成的意义上进行的移动之间使活塞进一步在缸中返回移动，返回移动的幅度比在其在制动压力形成的意义上进行第一次移动时已经移动的幅度大，那么制动液就从制动液储存容器通过第二制动液管路和布置在其中的止回阀流入到所述缸中，只要助力车辆制动设备正常并且具有完全的功能能力。为了产生相同的制动压力，在这种情况下，活塞必须在其两次在制动压力形成的意义上进行的移动中在缸中移动得一样远。因为活塞在其两次在制动压力形成的意义上进行的移动之间已经返回移动，返回移动的幅度比在其在制动压力形成的意义上进行第一次移动时大，所以活塞在其在制动压力形成的意义上进行第二次移动时不再在缸中到达与在其在制动压力形成的意义上进行第一次移动时相同的位置。如果活塞的、在其在制动压力形成的意义上进行第二次移动时的移动行程更长并且压力梯度（压力变化与活塞的移动行程的比例）与在第一次移动时相同或相似，那么这就可以推断出在活塞返回移动时没有制动液或有太少的制动液从制动液储存容器流入到助力制动压力产生器的缸中，也就是说第二制动液管路或止回阀具有减小的通流量或没有通流量。
从属权利要求的主题是在独立权利要求中所说明的发明的改进方案和有利的设计方案。
所有在说明书和附图中所公开的特征都能够单个地本身或者以原则上任意的组合在本发明的实施方式中得到实现。原则上能够实现本发明的以下实施方式，所述实施方式不是具有权利要求的全部特征而是具有其一个或多个特征。
附图说明
接下来借助于在附图中所示出的实施方式对本发明进行详细解释。其中：
图1示出了用于执行根据本发明的方法的助力车辆制动设备的简化的液压线路图；
图2示出了活塞行程曲线图；并且
图3示出了压力曲线图。
具体实施方式
图1所示出的助力车辆制动设备具有带有活塞-缸单元2的助力制动压力产生器1，所述活塞-缸单元的活塞3为了产生制动压力而能够借助于电动马达4通过螺旋齿轮传动机构在中间连接减速传动机构的情况下在活塞-缸单元2的缸5中移动。电动马达4具有旋转角传感器6，利用该旋转角传感器能够测量电动马达4的转子的或马达轴的旋转位置。电动马达4的转子的或马达轴的旋转与活塞3在缸5中的位移成比例，因此根据电动马达4的转子的或者马达轴的旋转位置和旋转角能够计算活塞3在缸5中的位置和移动行程。助力制动压力产生器1的活塞-缸单元2的活塞3和缸5也能够被理解为助力制动压力产生器1的活塞3和缸5。
压力传感器7被连接到助力制动压力产生器1的缸5上。
通过隔离阀8和进口阀9，一个或多个液压的车轮制动器10被连接到助力制动压力产生器1的活塞-缸单元2的缸5上。
能用人力操纵的主制动缸11通过助力制动压力产生器1的隔离阀8与车轮制动器10的进口阀9之间的隔离阀12被连接到车辆制动设备上。主制动缸11在助力制动时用作用于有待用助力制动压力产生器1来产生的制动压力和/或车轮制动器10中的有待用进口阀9和出口阀13来调节的车轮制动压力的目标值设定器（Sollwertgeber）。因此，主制动缸11具有踏板行程传感器14和/或压力传感器15。在助力制动中，主制动缸11的隔离阀12关闭并且主制动缸11由此在液压方面与助力车辆制动设备的其他部件液压分离、特别是与车轮制动器10和助力制动压力产生器1分离。
为了进行助力制动而打开助力制动压力产生器8的隔离阀8并且用助力制动压力产生器1来产生制动压力。在助力制动压力产生器1发生故障或失灵的情况下，能够利用能用人力操纵的主制动缸11来操纵助力车辆制动设备。
图1示出了单回路车辆制动设备。能够考虑作为双回路或多回路车辆制动设备的实施方式，其方法是，将多个车轮制动器10通过多个隔离阀8在液压方面并联地连接到助力制动压力产生器1的缸5上并且通过多个隔离阀12在液压方面并联地连接到主制动缸11上（未示出）。
助力制动压力产生器1的隔离阀8和车轮制动器10的出口阀13在其无电流的基础位置中关闭，并且主制动缸11的隔离阀12和车轮制动器10的进口阀9在其无电流的基础位置中是打开的2/2换向磁阀。能够考虑其它实施方式。
主制动缸11具有无压力的制动液储存容器16，车轮制动器10也通过出口阀13被连接到所述制动液储存容器上。制动液储存容器16具有填充水平传感器17，利用该填充水平传感器能够测量制动液储存容器16的填充水平或者能够确定低于所规定的最低填充水平的情况。每个车轮制动器10都具有进口阀9和出口阀13，利用所述入口阀和出口阀能够调节每个车轮制动器10中的车轮制动压力并且能够以本身已知的方式执行滑转调节。这样的滑转调节尤其是防抱死调节、驱动滑转调节和行驶动力调节/电子稳定程序，对其而言通常使用缩写ABS、ASR和FDR/ESP。
助力制动压力产生器1的缸2通过第一制动液管路18和第二制动液管路19与制动液储存容器16相连接。如果使活塞3在制动压力形成的意义上从基础位置移动一小段距离，所述第一制动液管路18就被活塞3闭锁。在第二制动液管路19中布置有能够朝缸5的方向通流的止回阀20。
为了根据本发明来检查助力车辆制动设备，将助力制动压力产生器1的活塞3移到缸5中的以下位置中，在所述位置中活塞将第一制动液管路18闭锁。这个位置在图2的曲线图中用I来表示。缸5无压力，这一点能够通过以下方式来实现，即：打开助力制动压力产生器1的隔离阀8，使得活塞3通过助力制动压力产生器1的打开的隔离阀8、主制动缸11的打开的隔离阀12并且通过主制动缸11将制动液排挤到无压力的制动液储存容器16中。作为替代方案或补充方案，能够打开至少一个车轮制动器10的出口阀13，使得助力制动压力产生器1的活塞3通过助力制动压力产生器1的隔离阀8和一个或多个车轮制动器10的进口阀9和出口阀13将制动液排挤到制动液储存容器16中。
在检查开始时，关闭助力制动压力产生器1的隔离阀8，使得制动液被围在助力制动压力产生器1的缸5中，因为活塞3将第一制动液管路18闭锁。制动液只能通过第二制动液管路19中的止回阀20流入到助力制动压力产生器1的缸5中。使活塞3返回移动一段距离到在图2中用II表示的位置中，以用于确保缸5没有压力。位置II本身是在检查开始时活塞3的起始位置。
从缸5没有压力的位置II开始，第一次在制动压力形成的意义上使助力制动压力产生器1的活塞3移动所规定的行程或者一直移动直至达到缸5中的所规定的压力。活塞3的、在压力形成的意义上进行的第一次移动结束时的位置在图2中用III来表示。助力制动压力产生器1的缸5中的压力升高在图3的曲线图中示出。
在活塞3的、用于保持压力的、在“IV”处结束的停止状态阶段之后，使缸5中的活塞3朝与压力形成相反的方向返回移动到在图2中用V表示的位置中。活塞3的返回移动优选长于在压力形成的意义上从位置II到位置III中的第一次移动。由于更长的返回移动，活塞3通过第一制动液管路19和止回阀20将制动液从制动液储存容器16吸到缸5中。活塞3没有如此远地返回移动到其打开第一制动液管路18的程度。
在返回移动之后，在压力形成的意义上在缸5中第二次移动活塞3，并且更确切地说特别是使其移动与在压力形成的意义上进行第一次移动时相同的行程或者直至达到相同的压力。在压力形成的意义上使活塞3进行的第二次移动的结束在图2中用VI表示，紧接着重新出现活塞3的停止状态阶段，以用于保持缸5中的压力，此后能够将活塞3移回到其基础位置中，在所述基础位置中该活塞打开第一制动液管路18。在所描述的检查期间，活塞3从未到达这个基础位置中，而是第一制动液管路18总是保持被闭锁的状态。
如果活塞3在其在压力形成的意义上进行从位置V到位置VI的第二次移动时需要更长的行程，以用于产生所规定的压力，或者在移动行程相同时压力形成水平比在压力形成的意义上进行的第一次移动时低，那就可以认为，在活塞3在两次在压力形成的意义上的移动之间返回移动时来自制动液储存容器16的空气通过第二制动液管路19和止回阀20进入到助力制动压力产生器1的缸5中 。其原因可能是制动液储存容器16中的太低的制动液水平。如果填充水平传感器17在与此一致的情况下显示出太低的制动液水平，则应该补加制动液。如果填充水平传感器17显示出足够的制动液水平，则应该检查和/或更换填充水平传感器17。
在活塞3在压力形成的意义上进行第二次移动时出现较低的压力形成水平和/或较长的活塞行程的另一个原因是止回阀20没有打开或者没有完全打开，从而在活塞3返回移动时没有制动液或者太少的制动液进入到缸5中。尤其如果在活塞3在压力形成的意义上进行第二次移动时必须将所述活塞3移到和在活塞在压力形成的意义上进行第一次移动时相同的位置中，尽管返回移动更长，那么这就暗示了可能没有打开的止回阀20。如果在所述两次移动中的压力梯度相同或者相似，这一点尤其适用。压力梯度是压力变化与移动行程的比例。
