Description

用于运行制动系统的方法和装置以及制动系统
技术领域
本发明涉及一种用于运行机动车的液压的制动系统的方法，所述液压的制动系统具有至少一个能液压操纵的车轮制动器、带有用于预先给定目标-制动力矩的能操纵的制动踏板的制动踏板机构以及为了根据所述目标-制动力矩产生液压压力而被电操控的压力产生器，其中在正常运行中将所述压力产生器的运行电流限制到能预先给定的第一极限值。
此外，本发明涉及一种用于实施所描述的方法的装置以及一种具有这样的装置的制动系统。
背景技术
开头所提到的类型的方法、装置和制动系统已经从现有技术中为人所知。对于常规的制动系统来说利用制动踏板机构中的真空制动力放大器，以用于增强由驾驶员施加到制动踏板上的制动力并且将其导入到所述制动系统的液压回路中，而在此也知道下述制动系统，对于所述制动系统来说放弃真空制动力放大器并且换之使用能够电操控的压力产生器。所述压力产生器在没有与制动踏板机械地耦合的情况下产生液压压力。更确切地说，通过一个或者多个传感器来检测和监控对于所述制动踏板的操纵并且根据制动踏板操纵来操控所述压力产生器。所述压力产生器比如是泵，为该泵分配了电动马达，以用于以电液的方式来调节所述制动系统中的压力。在此，如此操控所述压力产生器，从而在所述制动系统的一个或者多个车轮制动器上设定由驾驶员通过对于所述制动踏板的操纵来要求的目标-制动力矩，以用于使机动车减速。
为了防止所述压力产生器或者其电动马达的过热，如此操控所述电动马达，从而在转速低的情况下将转矩并且由此将运行电流限制到第一极限值。
发明内容
所述按本发明的方法拥有以下优点：根据对于制动踏板的操纵的方式对制动踏板机构进行监控，并且在检测到高动态的操纵时取消对于所述运行电流的限制。所述按本发明的方法具有以下优点：在高动态的制动过程中在短暂的时间里向驾驶员提供所期望的制动力矩，然而其中保证，持久地防止所述压力产生器、尤其是其电动马达的过热。取消用于高动态的制动过程的限制，由此使用者能够在高动态的制动过程中在短暂的时间里查询制动力矩。因为高动态的制动过程没有待续长的时间，而是其特征尤其在于其时间的短暂，所以几乎排除了所述电动马达的、由于该电动马达的负荷的短时间的提高而引起的过热。
按照本发明的一种优选的改进方案来规定，如果所检测到的制动踏板操纵速度超过能预先给定的第二极限值，则断定高动态的操纵。为此，适当地对所述制动踏板的操纵速度进行监控并且将其与第二极限值进行比较。如果所检测到的速度超过所述第二极限值，那就取消前面所描述的、对所述运行电流的限制。尤其借助于配属于所述制动踏板的行程传感器来检测制动踏板操纵速度。通过所述行程信号的、关于时间的简单的求导能够计算所述制动踏板的运动速度，从而对于所述方法来说能够在短暂的时间里判断，所检测到的制动过程或者所检测到的制动踏板操纵是高动态的操纵还是正常的操纵。
此外优选规定，如果所检测到的制动踏板行程超过能预先给定的第三极限值，那就识别出高动态的操纵。在此，尤其在不取决于对于制动踏板操纵速度的考虑的情况下，将制动踏板行程与第三极限值进行比较。尤其如此选择所述第三极限值，从而防止虽然用高的速度进行的、但是仅仅要求小的制动力矩的制动踏板操纵没有被检测为高动态的制动踏板操纵。
此外优选规定，根据所述压力产生器的运行温度来预先给定所述第一极限值。由此实现以下优点：对所述压力产生器进行动态的操控，所述动态的操控取决于所述压力产生器的当前的运行温度。尤其将所述当前的运行温度与最大允许的运行温度进行比较，以用于确定，所述温度是否允许进一步升高。相应地改变所述第一极限值，从而可靠地防止超过极限温度。在此要认为，高动态的制动过程仅仅短时间地并且由此可忽略地提高所述运行温度。
此外，按照一种有利的改进方案来规定，仅仅在转速低于第四极限值时通过所述第一极限值对所述运行电流进行限制。由此考虑到，尤其对于低的转速来说所述用于驱动压力产生器的转矩是高的，从而刚好在这里出现高的运行电流，所述高的运行电流导致所述压力产生器、尤其是其电动马达的变热。但是，如果所述压力产生器在具有高的转速的转速范围内工作，在所述转速范围内同样需要高的运行电流，那么由于高的转速而需要小的转矩，因而加热程度更小并且就此而言能够取消限制到所述第一极限值的做法。
尤其规定，根据在进行长时间制动时所述压力产生器的允许的运行温度来预先给定所述第一极限值。在这种情况中，尤其固定地并且不是动态地预先给定所述第一极限值，并且所述第一极限值相应于下述运行电流，在进行长时间制动时最大可以出现所述运行电流，而所述压力产生器的运行温度没有超过临界的数值。
按照本发明的一种优选的改进方案来规定，所述制动踏板机构根据所述制动踏板操纵的所检测到的方式来产生状态信息并且将其发送给对所述压力产生器进行操控的控制器。所述制动踏板机构由此将是否进行了高动态的制动踏板操纵的信息自己发送给所述控制器，所述控制器而后根据这种信息来操控所述压力产生器或者取消或者设定通过所述第一极限值进行的限制。
所述按本发明的装置的特征在于一种控制器，该控制器专门被安排用于在按照规定地使用时实施所述按本发明的方法。在此产生已经提到的优点。
所述按本发明的制动系统的特征在于所述按本发明的装置。由此产生已经提到的优点。
另外的优点和优选的特征以及特征组合尤其从前面所作的描述和优选实施例中产生。
附图说明
下面要借助于附图对本发明进行详细探讨。为此：
图1以示意图示出了机动车的液压的制动系统；
图2示出了用于对一种有利的用来运行制动系统的方法进行解释的流程图；并且
图3示出了在正常运行中并且在高动态的制动过程中所述压力产生器的电动马达的转矩特性曲线。
具体实施方式
图1以简化的图示示出了一种用于在这里未详细示出的机动车的制动系统1。所述制动系统1具有多个车轮制动器2，所述车轮制动器能够由所述机动车的驾驶员通过作为行车制动器的制动踏板机构3来操纵。所述车轮制动器2在此通过LR、RF、LF和RR来表示，由此对其在所述机动车上的位置或者分配进行解释，其中LR代表着左后，RF代表着右前，LF代表着左前并且RR代表着右后。在所述制动踏板机构3与所述车轮制动器2之间构造了两条制动回路4和5，其中所述制动回路4配属于所述车轮制动器LF和RR并且所述制动回路5配属于所述车轮制动器LR和RF。所述两条制动回路4和5相同地构造，因而下面要借助于所述制动回路4对两条制动回路4、5的构造进行详细解释。
所述制动回路4首先与所述制动踏板机构3的主制动缸6相连接，其中所述主制动缸6在此构造为双活塞缸或者串联式缸，并且其中所述制动踏板机构3此外具有能够由驾驶员操纵的制动踏板7。所述制动回路4具有转换阀8，所述转换阀紧跟在所述主制动缸6之后。所述转换阀8构造为无电流地打开的结构并且允许所述制动回路的液压介质、也就是制动液朝两个方向流动。此外，所述转换阀8在分别中间连接进口阀10的情况下与所述两个车轮制动器2相连接，所述进口阀构造为无电流地朝两个方向打开的结构。此外，为所述制动回路4的车轮制动器2分别分配了构造为无电流地关闭的结构的出口阀11。所述出口阀11在出口侧与液压储箱9相连接，所述液压储箱向所述主制动缸6供给液压介质。此外，在出口侧所述出口阀11与泵13的吸入侧相连接，所述泵在压力侧在所述转换阀8与所述进口阀10之间与所述制动回路4相连接。所述泵13在此构造为活塞泵并且与电动马达14机械地耦合，其中所述泵13和所述电动马达14一起形成所述制动系统1的压力产生器15。在此规定，所述电动马达14配属于两条制动回路3、4和5的泵13。作为替代方案，也能够规定，每条制动回路4、5具有自身的电动马达14。此外，为所述主制动缸6分配了液压的踏板感觉模拟器12。
如果关闭所述制动回路4、5的两个转换阀8，那么所述液压压力就留在所述制动回路4、5的处于所述转换阀后面的区段中，也就是被关在或者被维持在所述转换阀与所述车轮制动器2之间，即使而后通过驾驶员给所述制动踏板7卸荷。为了进行制动力放大而操控所述压力产生器15，从而附加于对于所述制动踏板7的操纵而通过所述压力产生器15在所述制动系统1中自动化地提高所述液压压力，使得驾驶员能够以小的力的消耗来产生高的制动力矩。
图2示出了用于对一种有利的用来运行所述制动系统的方法进行解释的简化的流程图。随着对于所述制动机构3的制动踏板7的操纵，在第一步骤S1中开始所述方法。在紧随此后的询问S2中检查，所述制动踏板操纵是不是高动态的制动踏板操纵。为此要检测所述制动踏板7的操纵速度或者操纵行程并且将其相应地与极限值进行比较。如果所检测到的制动踏板行程超过所分配的极限值并且所述操纵速度高于相应的极限值，那就断定，进行了高动态的制动操纵（是）。但是，如果所述操纵速度小于所述极限值并且/或者所述制动踏板没有运动超过通过所属的极限值允许的踏板行程，那就断定，不存在高动态的制动踏板操纵（否）并且进行到步骤S3。在这个步骤中，将用于所述压力产生器15的运行电流限制到允许的第一极限值。
为了防止所述压力产生器15的过热或者所述压力产生器15的电动马达的过热，在此规定，在正常运行中通过第一极限值来限制所述压力产生器的运行电流。这一点要借助于在图2中示出的方法来进行详细解释。
而后，用如此受到限制的运行电流在步骤S4中操控所述压力产生器15，以用于产生液压压力。但是，如果在步骤S2中发现，所述制动踏板操纵是高动态的制动踏板操纵（是），那就从步骤S2继续进行到步骤S4，从而不进行或者说取消对于所述运行电流的限制。由此，能够在高动态的制动过程中向所述压力产生器15供给提高的运行电流，使得其在转速低时也提供高的转矩，从而在所述制动系统1中在极短的时间里形成所述液压压力。仅仅对高动态的制动过程来说取消所述限制，由此在正常运行中保证不超过所述运行温度。在高动态的制动过程中，热负荷取决于所述运行电流的水平和持续时间。因为在进行高动态的制动时，尤其如果还存在低的转速，所述运行电流就仅仅在短暂的时间里是高的，所以对于运行温度的损害在这个短暂的时间里能够忽略。相应地，允许通过所描述的方法来有利地将所述运行电流提高到超过所述第一极限值。由此，在高动态的制动过程中就像在正常的制动过程中一样提高所述电动马达14的转矩，其中精确的大小或者转矩升高取决于所述电动马达的尺寸设计和所实现的电流极限。
图3为此示范性地以图表关于转速n作为转矩Md示出了在正常运行中（k1）并且在高动态的制动过程中（k2）所述压力产生器15的电动马达14的转矩特性曲线。可以看出，在高动态的制动过程中允许比在转速低时高的转矩，而对于高于2000转的较高的转速来说特性曲线k1和k2则彼此叠放。
