Description

液压式车辆制动设备
技术领域
本实用新型涉及一种液压式车辆制动设备。
背景技术
从现有技术中已知用于控制车辆的操纵稳定性的系统、即所谓的ABS系统和ESP系统的各种实施方式。借助于这种系统，通过调节液压式车辆制动设备的车轮制动器的制动压力来影响车辆的行驶动作。在此涉及：防抱死控制(ABS)，其用于在制动过程期间防止单个车轮抱死；驱动防滑控制(ASR)，其用于防止驱动车轮打滑；电子制动力分配(EBV)，其用于调节在前桥和后桥之间的制动力分配；以及横摆力矩控制(ESP)，其用于在车辆围绕其车辆竖轴横摆时稳定车辆状态。
这种液压式制动设备原则上包括两个制动回路，这两个制动回路各自具有两个车轮制动器，所述车轮制动器通过相应的制动回路与可借助于制动踏板致动的制动主缸液压连接。为每个车轮制动器配设无电流时打开/常开的进入阀和无电流时关闭/常闭的排出阀，以用于调节在车轮制动器上的液压压力。在此，车轮制动器通过进入阀与制动主缸连接，而排出阀通向低压蓄能器。借助制动回路的隔离阀使车轮制动器与制动主缸液压分离，以便主动地借助于例如设计为活塞泵的压力供应装置在车轮制动器上产生制动压力，即无需驾驶员操作制动踏板。通过这种自主的压力形成，可以实现许多功能，例如ABS功能、ASR功能、ESP功能等。
制动助力器在制动过程中对由驾驶员在制动踏板上向制动主缸施加的力进行辅助。真空制动助力器和液压制动助力器是最常见的实施方式。
真空制动助力器或液压制动助力器的替代方案是所谓的机电制动助力器，其中，电机产生转矩，该转矩通过联接装置转换为制动助力器的辅助力。
实用新型内容
因此本实用新型的目的是，提供一种液压式车辆制动设备，通过该车辆制动设备以成本有利的方式实现对车辆的操纵稳定性控制。
在液压式车辆制动设备中，该液压式车辆制动设备具有可通过制动踏板经由机电的制动助力器致动的制动主缸、与制动主缸液压连接的液压单元、与液压单元液压连接的车轮制动器和ABS控制器，
-ABS控制器被构造成，为防止各车轮抱死而实施防抱死控制，
-ABS控制器被构造成，如此驱控机电的制动助力器，使得借助于液压单元产生车轮独有的制动压力，以用于实施横摆力矩控制。
在该方法中，借助于ABS控制器和与该ABS控制器共同作用的机电的制动助力器不仅能实现规定的功能，而且还实现了ESP功能，该ESP功能作为横摆力矩控制通过产生车轮独有的制动压力实现。机电的制动助力器的规定功能是根据由驾驶员操作的制动踏板的制动踏板行程或制动踏板压力而产生的制动力。ABS控制器的规定功能是根据车轮转速传感器的传感器信号实施防抱死控制。为了实施横摆力矩控制，如此设计ABS控制器，使得机电的制动助力器为此提供所需的制动压力以实现车轮独有的压力控制。
根据本实用新型的液压式车辆制动设备的优点在于，为了实现本液压式车辆制动设备除了ABS控制器外不需要ESP控制器，而是通过ABS控制器与机电的制动助力器的共同作用实现ESP功能。
本实用新型的特别有利的改进方案提出，ABS控制器被构造成，如此驱控机电的制动助力器，使得借助于液压单元产生车轮独有的制动压力用于实施驱动防滑控制(ASR控制)。这种ASR控制也是典型的ESP功能。
根据本实用新型的另一有利的设计方案，ABS控制器被构造成，在制动过程期间调节在车辆前桥和车辆后桥之间的制动力比例。由此电子的制动力控制(EBV)作为另外的典型的ESP功能实现。
根据本实用新型的另一个特别有利的改进方案，所述液压式车辆制动设备构造成，为了产生车轮独有的制动压力：
-在使机电的制动助力器建立制动压力期间，短暂地打开液压单元的为车轮配设的至少一个排出阀从而为液压单元的低压蓄能器填充液压流体，
-在关闭排出阀的情况下借助于液压单元的液压泵将液压流体从低压蓄能器输送回车轮的制动回路中从而提高压力。
在这些功能中，低压蓄能器与液压泵共同作用其起关键作用，用于在由制动助力器引起的压力建立期间通过由机电的制动助力器产生的液压压力增加制动压力。为此，在制动过程期间为车轮制动器配设的排出阀短暂地打开，例如打开20ms，由此基于由机电的制动助力器产生的最大压力以液压流体来影响低压蓄能器。在关闭排出阀之后，借助于液压泵将液压流体从低压蓄能器中输送到所述车轮制动器的制动回路中，由此通过由机电的制动助力器产生的液压压力使制动回路中的压力升高。机电的制动助力器的“回压”——即液压泵不对抗机电的制动助力器的驱动电机进行输送——由于机电的制动助力器的机械驱动的受限的效率而受到阻碍。因此通过机电的制动助力器所产生的液压压力的大小由机电的制动助力器的效率决定。由于在机电的制动助力器中的机械损耗，在制动回路中产生的液压压力比无机械损耗时能产生的液压压力低。在相反的情况下，从制动回路向机电的制动助力器的驱动电机流动能量时也出现相同的机械损耗，也就是说，机电制动助力器所能抵抗的液压压力大于制动回路中由机电的制动助力器实际产生的液压压力并且取决于机电的制动助力器的效率值。基于效率因数的平方，由机电制动助力器在制动回路中产生的液压压力比导致机电的制动助力器回移的液压压力低。
借助于所填充的低压蓄能器与液压泵的共同作用所产生的压力提升优选被用于制动衰减补偿(Fading-Kompensation)。制动衰减(Fading)被理解为，在由车辆驾驶员发出制动过程期间由于车轮制动器的制动衬片过热而造成的制动作用减弱。
根据本实用新型，这种液压式车辆制动设备仅包括机电的制动助力器与制动踏板和制动主缸的组合以及具有用于实现ESP功能的ABS控制器。
附图说明
下面参照附图根据实施例描述本实用新型。
图1示出用于描述根据本实用新型的实施例的液压式车辆制动设备。
具体实施方式
在图1中示出的车辆的液压式车辆制动设备1包括连同制动踏板2.2和驱动电机2.1的机电的制动助力器2.1以及制动主缸2.3，该制动主缸与液压单元3液压连接，该液压单元自身通过第一制动回路3.1与左前方的车轮FL和右后方的车轮RR的车轮制动器4.1液压连接，并通过第二制动回路3.2与右前方的车轮FR和左后方的车轮RL的车轮制动器4.2液压连接。
左前轮FL和右后轮RR的液压单元3的第一制动回路3.1通过液压管路L1与制动主缸2.3连接。右前轮FR和左后轮RL的液压单元3的第二制动回路3.2通过另一液压管路L2与制动主缸2.3连接。
液压式车辆制动设备1还具有ABS控制器3.3，该ABS控制器根据传感器信号控制液压单元3的进入阀和排出阀。制动力控制器2.1的制动助力器控制器2.10通过控制和数据线路L与ABS控制器连接。
根据由传感器检测到并由制动助力器控制器2.10评估的、由对制动踏板2.2的操作而产生的操作变量(例如踏板行程、踏板力)，制动助力器2.1的通过传动机构致动制动主缸2.3的驱动电机2.11如此被制动助力器控制器2.10驱控，使得在液压管路L1和L2中产生表明操作变量的液压压力，该液压压力被进一步传递给至少一个车轮制动器4.1或4.2。
因此，例如，借助于制动助力器2.1产生的液压压力被输送到第一制动回路3.1的打开的进入阀3.10和3.11以及第二制动回路3.2的打开的进入阀3.20和3.21的入口侧，从而在车轮FL、RR、FR和RL的车轮制动器4.1和4.2上形成与被操作的制动踏板2.2相应的液压制动压力。进入阀3.10和3.11以及3.20和3.21在无电流时是打开的。
第一制动回路3.1的无电流时关闭的排出阀3.12和3.13将车轮制动器4.1与低压蓄能器3.14连接，该低压蓄能器3.14进而与作为压力源的液压泵3.41的吸入侧连接，其中液压泵3.41在压力侧通过阻尼腔3.5与制动主缸2.3连接。相应地，第二制动回路3.2的无电流时关闭的排出阀3.22和3.23将车轮制动器4.2与低压蓄能器3.24连接，该低压蓄能器又与作为压力源的液压泵3.42的吸入侧连接，其中该液压泵3.42也通过阻尼腔3.5与制动主缸2.3连接。
随着对制动踏板2.2的操作，第一制动回路3.1的排出阀3.12和3.13以及第二制动回路3.2的排出阀3.22和3.23关闭。
因此，利用该制动助力器2.1与制动踏板2.2和制动主缸2.3的共同作用实现了制动助力器的规定功能，即，在车辆驾驶员操作制动踏板2.2时在制动回路3.1和3.2中形成液压压力，该液压压力在车轮制动器4.1和4.2上引起预期的制动力。
两个液压泵3.41和3.42被电机3.4驱动，该电机能由ABS控制器3.3进行电控。在此，以这样的方式驱控电机3.4，使得液压泵3.41和3.42可以通过在吸入侧从低压蓄能器3.14和3.24吸入制动介质而在高压侧形成制动压力。由液压泵3.41和3.42建立的制动压力分别由传感器确定。电机3.4的转速传感器用于确定所输送的压力介质体积。为车轮制动器4.1和4.2提供液压泵3，以便在由ABS控制器3.3发出的ABS干预的情况下，将在自主压力形成时进入低压蓄能器3.14或3.24中的制动介质再次输送回第一制动回路3.1和/或第二制动回路3.2。
除了ABS控制器3.3的规定功能、即借助于液压单元3实现防抱死控制之外，该ABS控制器3.3还被构造成，执行横摆力矩控制，以产生在调节车辆的操纵稳定性的意义下的ESP功能。
为了在横摆力矩控制的意义上实现ESP功能而在制动回路3.1和/或3.2中自主地形成制动压力时，就是说，独立于驾驶员对制动踏板的操作，ABS控制器3.3根据传感器信号生成用于制动助力器控制器2.10的控制信号，该制动助力器控制器本身与控制信号相应地驱控驱动电机2.11，以产生ABS控制器3.3所要求的制动压力。通过由ABS控制器3.3同时控制液压单元3的排出阀和进入阀，产生了用于执行横摆力矩控制的车轮独有的制动压力。
通过产生这种车轮独有的制动压力，还可以产生驱动防滑控制(ASR控制)和电子制动力控制(EBV)。
因此，用于这些ESP功能的制动助力器2.1会根据ABS控制器3.3的要求提供所需的制动压力。
现在可能是这样的情况，例如在制动衰减时，由制动助力器2.1产生的制动压力的大小小于ABS控制器3.3所要求的制动压力。
然而为了提高在制动回路3.1或3.2之一中由制动助力器2.1产生的制动压力，使用低压蓄能器3.14或3.24。为此，ABS控制气3.3被设计为用于实施以下功能。
首先，借助于制动助力器2.1，在制动回路3.1或3.2中建立最大压力，并通过短暂打开排出阀3.12和3.13或3.22和3.23同时为低压蓄能器3.14或3.24填充液压流体。排出阀3.12和3.13或3.22和3.23的打开时间取决于低压蓄能器3.14或3.24的体积大小以及液压流体流过排出阀3.12、3.13或3.22、3.23的流速，例如打开时间为20毫秒。
随着排出阀3.12和3.13或3.22和3.23的关闭，通过由ABS控制器3.3适当地驱控电机3.4，液压泵3.41或3.42将液压流体从低压蓄能器3.14或3.24输送回制动回路3.1或3.2中，由此制动回路3.1或3.2中的液压压力升高。
但是，压力升高的程度不得导致机电的制动助力器2.1的“回压”。
根据制动助力器2.1的有限的效率，可以设定压力增加，使得液压泵3.41或3.42不会对抗驱动电机2.11进行输送。由于机电的制动助力器2.1中的机械损耗，在制动回路3.1或3.2中产生的液压压力低于在无机械损耗时可以产生的液压压力。即使在相反的情况下，能量也从制动回路3.1或3.2流向机电的制动助力器2.1的驱动电机2.11时，也发生相同的机械损耗，就是说，机电的制动助力器2.1可以抵抗的液压压力大于由机电的制动助力器2.1在制动回路中实际产生的液压压力，并且取决于机电的制动助力器2.1的效率值。基于效率因数的平方，由机电的制动助力器2.1在制动回路3.1或3.2中产生的液压压力比导致机电的制动助力器2.1的回推的液压压力低。
因此，借助于液压泵3.41或3.42将制动流体的一定的体积从低压蓄能器3.14或3.24输送到制动回路3.1或3.2中，使得由此在制动回路3.1或3.2中增加的压力不超过上述因数。
在图1中作为示例性实施例描述的车辆制动设备1可以成本有利地实现，这是因为为此仅需要ABS控制器3.3和制动力控制器2.1。为了产生ESP功能，仅需要ABS控制器3.3的软件适配。这意味着除ABS控制器外，不需要ESP控制器。
