Description

用于车辆的与轮胎相关的参量的测量和监控装置
技术领域
本发明涉及一种用于测量和/或监控车辆的与轮胎相关的测量参量的装置，所述装置包括用于发射、接收和处理信号的传感器单元，其中，由传感器单元的天线单元朝测量对象的方向可发出发射信号并且由测量对象反射的反射信号可被接收和可被评估，传感器单元具有发射/接收设备，借助所述发射/接收设备，可测量反射系数，所述反射系数作为在测量对象上反射的反射信号和发射信号的商构成，并且借助所述反射系数，可确定谐振频率和/或发射信号与反射信号之间的相位差。
背景技术
由DE 24 61 212 A1已知一种用于测量车辆的轮胎的压力装置，所述装置具有发射/接收设备，其包括用于产生微波频域的发射信号的振荡器。此外，发射/接收设备具有天线单元，通过所述天线单元，可以朝在车轮的轮辋底上设置的可压缩的测量对象的方向发出发射信号。此外发射/接收设备具有评估单元和接收天线，从而在可压缩的测量对象伸展时可以识别反射信号的频率变化。可压缩的测量对象具有依赖于轮胎的空气压力的可伸出的区段，所述区段导致反射信号的频率的改变并且由此可以导出轮胎压力变化。在已知的装置中不利的是，易受干扰性基于改变的环境条件相对大。
由DE 10 2009 013 458 A1已知一种用于测量和/或监控车辆的与轮胎相关的参数的装置，所述装置具有包括发射/接收设备的传感器单元以及评估单元和天线单元。发射信号从天线单元朝测量对象的方向发射。借助由测量对象反射的反射光束可以推断出测量对象与天线单元的距离。为此形成发射的功率与反射的功率的比。测量对象的当前的状态由此不可以被探测到。
发明内容
因此，本发明的任务是，这样进一步构成用于测量和/或监控车辆的与轮胎相关的参量的装置，使得确保与车辆相关的参量、尤其是轮胎压力的长期稳定的并且准确的测量。
为了解决该任务，本发明结合权利要求1的前序部分的特征在于，发射/接收设备具有矢量的网络分析仪和评估单元，从而通过检测发射信号和反射信号之间的相位差可确定与测量对象的距离。
按照本发明设置矢量的网络分析仪(VNA)，借助网络分析仪确保测量对象的便宜的并且鲁棒的监控或测量。有利地可以以一个并且相同的测量检测多个测量参数。测量数据传输在微秒范围中进行。此外按照本发明的装置具有小的重量。
按照本发明的进一步构成，可以将网络分析仪用于，检测轮胎压力、回转速度、车轮转向角、压缩深度、道路湿气以及轮胎中金属的杂质。
按照本发明的一种进一步构成，发射/接收设备设置在车辆的车轮罩中。测量对象构成为可压缩的结构元件，所述结构元件在通过轮胎和车轮的轮辋限定的内部空间内沿车轮的周向设置。发射/接收设备的天线单元定向到可压缩的结构元件上。仅检测可压缩的结构元件的区域。因为结构元件是压敏的，所以当轮胎压力改变时，所述结构元件进行径向的变形。材料常数εr因此改变。通过在可压缩的结构元件的径向的变形改变时形成入射的波(发射信号)和反射的波(反射信号)之间的相位差，可以推断出轮胎当前的压力。
按照本发明的一种进一步构成，可压缩的结构元件在外侧设有一定数量的反射器元件，从而可以改善结构元件的径向的变形的检测。优选地，反射器元件沿结构元件的周向加金属镀层或由金属材料制成。
按照本发明的一种进一步构成，发射/接收设备由控制单元借助伪随机数生成器操控，从而确保在分别配置给轮胎的发射/接收单元之间的干扰抑制。在相同的或其他的车辆上安装的各发射/接收单元之间的不希望的干扰的可能性由此减小。
按照本发明的一种实施形式，结构元件构成为微波空腔吸收器，从而通过确定谐振频率可导出轮胎的空气压力的改变。测量对象因此不是压力填充的基体。有利地，可以由此使信号处理变得容易。对集成到微波空腔吸收器中的柔性的膜片可以提出关于扩散特性相对小的要求。
按照本发明的一种进一步构成，可以在测量对象上沿周向设置沿不同的方向取向的反射器元件，优选以90°彼此错开，从而附加地确保车轮的回转角度测量。
按照本发明的一种进一步构成，发射/接收设备具有附加天线，所述附加天线的偏振平面相对于天线转动90°。由此可以同时检测两个反射信号，借此一方面确保轮胎压力并且另一方面确保车轮的回转角度测量。
按照本发明的一种进一步构成，发射/接收设备具有另一个天线，所述另一个天线定向到轮辋和/或车轮的宽度上，从而通过反射信号相对于发射信号的相位差，可确定在轮胎上或轮胎中的杂质。有利地可以因此确定，例如是否在轮胎中带入钉。
由其他的从属权利要求得出本发明其他的优点。

具体实施方式
用于测量和/或监控车辆的与轮胎相关的测量参数的装置具有传感器单元1，所述传感器单元主要具有集成在车辆(机动车)的车轮罩3中的发射/接收设备2。传感器单元1可以与位置远地、优选在车辆中设置的控制单元4通过信号线、例如CAN总线连接。为了测量或监控车辆的车轮5的轮胎压力，结构元件6作为测量对象设置在通过轮胎7和通过车轮5的轮辋8限定的内部空间9中。
按照根据图2的本发明的第一实施形式，结构元件6构成为可压缩的结构元件，所述结构元件定位或固定在轮辋8的轮辋底10上。
如由图1可看出的，发射/接收设备2具有矢量的网络分析仪VNA、评估单元11、在评估单元11和网络分析仪VNA之间设置的数字的信号处理器单元DSP以及包含发射/接收天线13和接收天线14的天线单元12。
网络分析仪VNA具有振荡器，所述振荡器产生在例如从300MHz至300GHz的微波频域中的正弦形的测量信号，优选在6.0和8.5GHz之间。发射/接收设备2具有用于信号处理和控制的微处理器，以及总线开关电路，所述总线开关电路用于通过与分散的或中央的位置远地设置的控制单元4的总线连接的导线连接的数据传输。优选地，发射/接收设备2附加地还具有DC-DC转换单元。网络分析仪VNA此外具有处理器以及测量门，其中，处理器通过定向耦合器与测量门连接。因此网络分析仪VNA可以产生发射信号S，所述发射信号通过天线单元12的发射/接收天线13传输到可压缩的结构元件6上。借助发射/接收天线3，接收在可压缩的结构元件上反射的反射信号R并且其在评估单元11中在确定发射信号S和反射信号R之间的相位差的情况下被评估。
为了提高测量精度，构成为圆形的连续软管的可压缩的结构元件6在外侧具有一定数量的沿周向取向地设置的第一反射器元件15，所述连续软管沿车轮5的周向在贴靠在轮辋底10上的情况下延伸。这些第一反射器元件15彼此成距离地沿周向设置。第一反射器元件15的长度确定发射信号S的工作效率或频率。可压缩的结构元件6可以构成为橡胶软管，而第一反射器元件15可以由金属材料制成。第一反射器元件15由吸收微波的材料制成。这引起，第一反射器元件15在反射测量的量方面显著相对于轮辋底10的否则强烈反射的背景中出现。这基于，在如下频率情况下，对于所述频率，反射器元件15具有大约λ/2的长度l1，波主要由所述反射器元件反射。未由该共振的第一反射器元件15反射的波的部分在其在轮辋底10上反射时由吸收微波的材料15两次传送，并且与此对应地减弱。因此可以由此作为干扰参量显著减少轮辋反射。此外可以由此简化加窗并且提高有效的信噪比。此外，在S11测量的量中被动的反射器元件15的工作频率的精确的确定也是可能的。对反射器元件15的制造精确性的要求可以由此减少。由S11测量的局部的最大值能够确定用于相位测量的精确的频率点。
为此有意义的是，发射/接收天线13仅定向到结构元件6或第一反射器元件15上。沿轴向方向最大的检测范围通过结构元件6的宽度b1限定。当轮胎压力仅利用结构元件6、而不利用第一反射器元件15测量，该条件适用。
如果轮胎压力的测量在包含结构元件6上以λ/2的长度l1设置的条状的反射器元件15的情况下进行，则发射/接收天线13的检测宽度限定为条状的反射器元件15的宽度b2。有利地，传感器单元1在该变型中能除了轮胎压力也测量车轮或轮胎的速度。
传感器单元1适合用于测量车轮5的压缩深度。为此相位评估通过网络分析仪VNA进行。
发射/接收设备2发射具有频率fi(i：运行指标)的正弦信号至轮胎。在轮胎的表面上，该正弦信号以不无显著的部分反射，即返回辐射。发射/接收设备2接收反射的并且在相位方面改变的正弦形的信号并且评价相位该测量在其他的频率情况下实施。由该相位通过发射频率然后能够确定距离信息。
在高频和微波范围中，对于在自由空间中的传播适用传播系数
β(fi)＝βi＝(2πfi)/cO， (1)
其中c0给出光速([6]：Heuermann，H.，Hochfrequenztechnik.LineareKomponenten hochintegrierter Schaltungen，Vieweg出版，ISBN 978-3-8348-07969-4，2.2009年五月版)。
因此对于反射测量在距离lx上的整个相位旋转对于在输入端和接收机上的频率点f1适用：
其中rx是轮胎表面的已知的反射系数。
该相位只在明确范围360°中测量。因此对于rg的整个的相位值依赖于相位rm的测量值适用：
Phase(rg)＝Phase(rm)+n·2π， (3)
其中n是整数，其此外还要被确定。
反射系数的测量值从下面的频率flu直至上面的频率flo作为rum和rom的相位值。在不同的测量点之间应该不给出相位突变，其在实际的数学中也能够简单地去除。
由这两个测量值和已知的所属的频率点能够确定相位关于频率的斜率：
在任意的频率fi时基于斜率给出基本相位旋转
方程(5)也能够以fo＝fi和fu＝0Hz和所属的相位值由方程(4)导出。通过接着的条件
180°＜abs(Phase(rim)+n·2π-fi S) (6)
找到用于n的正确的值。
对于每个频率点，基于方程(2)对于距离lx的长度确定适用的是：
除了精确的求解之外，rx也能够通过在已知的长度时的一次的测量确定。在实际中，方程(7)对于每个被测量的频率点被评估，借此通过随后的平均最小化随机的误差。
该测量的精确性随着带宽(f1o-f1u)和测量的数量升高。
现在计算的距离lx与压缩深度成比例。
该值此外也在其他的测量中需要，如在段落“加窗”中还要解释的。
为了确定轮胎压力，反射信号R的相位(S11测量)与发射信号S的相位比较。如果例如构成为橡胶软管的结构元件6不被压缩，则比在压缩的状态中显著更多的橡胶处于无线路程中。通过电介质的材料的改变的量，相位测量结果改变，其因此与压力成比例。结构元件6的变形的测量通过施加的反射器元件15简化，因为在反射器元件15的谐振频率情况下，所述反射器元件能够针对性地被考虑以用于相位测量。由此可以提高测量的精确性或减少对网络分析仪VNA的测量精度要求。
污物或其他干扰参量如轮辋反射、通过轮胎的相位旋转、在发射/接收设备2的壳体上的湿气薄膜在大小和相位方面改变传输特性。该干扰的效果可以通过对于所有测量的加窗去除。为此设置评估方法，使得反射信号R通过反傅立叶变换转换到时域中，然后已知的时域(壳体的表面被给定并且是固定的且轮胎距离被测量)被加窗出来并且于是因此被滤波的S11信号通过离散傅立叶变换转换回到频域中。现在在轮辋8的表面上产生的复杂的反射特性是占支配地位的信号。该方法首先通过按照大小和相位、即矢量地检测测量值而实现。
按照本发明的另一种实施形式，可压缩的结构元件6可以附加地具有第二反射器元件16，所述第二反射器元件沿轮胎7或轮辋8的轴向方向取向地设置。第二反射器元件16因此垂直于第一反射器元件15设置或具有与第一反射器元件15相同的长度l2＝λ/2。因为其以90°旋转，所以确保水平的位置并且借助第一反射器元件15确保垂直的极化。由此可以附加地还测量车轮5的回转角度。
按照本发明的按照图4的另一种实施形式，可以代替可压缩的结构元件6设置微波空腔吸收器17，所述微波空腔吸收器可以由开孔的泡沫层18覆盖，在所述泡沫层的外侧上设置所述一定数量的第一反射器元件15和/或第二反射器元件16。微波空腔吸收器17如泡沫层18环形地设置。微波空腔吸收器17直接贴靠在轮辋8的轮辋底10中。如由图5和6可看出的，微波空腔吸收器17具有包含纵向壁20的壳体19，所述纵向壁环形地沿轮辋底10延伸。微波空腔吸收器17部分圆形地沿周向延伸，其中，在两个端侧的柔性的膜片21之间的距离通过谐振频率预定。微波空腔吸收器17的长度l因此为λ/2。在壳体19的与轮辋底10背离的一侧上，在纵向壁20的外侧延伸有天线22。天线22通过纵向壁20的缝隙23在纵向壁20的内侧上触点接通。天线22通过隔离部24固定在壳体19的纵向壁20上。就此提供与压力相关的微波共振器，其谐振频率依赖于轮胎7的压力。柔性的膜片21可以例如由双轴向取向的聚对苯二甲酸乙二酯材料或膜片(bo-PET、Mylaer)形成。天线22构成为平面的天线。
为了使该测量***具有发射信号和接收机之间的需要的串扰隔离，必需一次地在生产中实施***误差校正，如在每个可购买的VNA中的情况。然而该***误差校正必须在自由空间中实施。为此可以考虑的方法在如下文件“Heuermann,H.,Sichere Verfahren zurKalibrierung von Netzwerkanalysatoren für koaxiale und planareLeitungssysteme,博士论文,高频技术研究所,鲁尔大学，波鸿,1995,ISBN 3-8265-1495-5)”中发表。优选能够使用双门方法(Zweitorverfahren)LNN。备选地，能够由描述的S-3-R-方法引出Μ-3-R-方法，其同样对于自由空间测量能够被使用。
在M-3-R-方法中实施四个单门测量：
1)M-测量：天线朝天空(或吸收器)的方向定向。
2)3-R-测量：在三垂面反射器上的反射在3个部位中以已知的距离测量。
由这些校准测量对于每个频率点计算3-项-方法的3个复杂的误差系数。利用这3个复杂的误差系数或项，纠正测量值并且此外计算发射和接收支路之间的串扰。
该VNA校准在所述加窗之前实施。
按照本发明的按照图7的另一种实施形式，也可以利用发射/接收设备2，以便发射和接收具有微波空腔吸收器17的工作范围外的频率的发射信号S，以用于车轮参数测量。微波空腔吸收器17相对于共振器反射缓冲该频率的反射信号R'。借此可以在测量结果中较容易地发现共振器。
第一反射器元件15和第二反射器元件16引起，在车轮的直线运行(没有转向偏转)时只有由第一反射器元件15的反射被检测。在转向偏转时，出现在第二反射器元件16上的附加的反射。在45°的转向偏转时，第一反射器元件15和第二反射器元件16的反射份额大小相等。
为了测量转向角，发射/接收设备2备选地也可以具有附加的接收天线14，所述接收天线的偏振平面以90°相对于接收天线13转动。在直线运行时，天线14没有接收信号。随着逐步的转向偏转，接收天线14的信号变得更大并且在接收天线13上变得更小。由第一接收天线13和第二接收天线14的两个确定的反射信号R之间的相位差获得是向右还是向左转向的方向。
如果传感器单元应该可以识别在轮胎7中或上的杂质，则必须检测轮胎7的整个宽度。发射/接收天线13必须具有方向特性，其一方面在宽度中覆盖整个轮胎并且另一方面被检测的部段沿轮胎7的周向尽可能窄。因此可以沿周向进行轮胎7的扫描。在轮胎7的一个部段中存在外来的物体、例如钉时，得出另一个不同于轮胎7的其他的沿周向被检测的部段的反射值R。
传感器单元1的操控优选借助伪随机数生成器进行，从而分别配置给车轮5的发射/接收设备2时移地***控并且相互的干扰被避免。
