測(cè)量 Carrying out the measurement
為了分析測(cè)試車輛中的電路，汽車制造商、開發(fā)服務(wù)提供商和供應(yīng)商通常使用MULTI-8測(cè)量模塊，即具有8個(gè)并聯(lián)獨(dú)立輸入的毫伏表。用于電流、電壓和溫度測(cè)量的不同探頭可以連接到所有輸入端。這些探針由測(cè)量模塊自動(dòng)識(shí)別。為了在計(jì)算測(cè)量值時(shí)達(dá)到盡可能高的精度，相應(yīng)樣品的校準(zhǔn)值被傳輸?shù)綔y(cè)量模塊并用于計(jì)算。測(cè)量數(shù)據(jù)通過CAN和/或以太網(wǎng)傳輸，每個(gè)通道最多可輸出8 kHz。例如，多種配置選項(xiàng)可以通過不同的操作模式減少數(shù)據(jù)量，并對(duì)測(cè)量值進(jìn)行平均。
這些模塊優(yōu)選安裝在車輛內(nèi)部，例如通過車輛保險(xiǎn)絲盒直接連接到電路中，見圖1。
為了防止極其昂貴的測(cè)試車輛發(fā)生可能的短路，測(cè)量電路受到原裝車輛保險(xiǎn)絲的保護(hù)。測(cè)量分流器在獨(dú)立外殼中的布置確保了測(cè)量值不會(huì)因熱效應(yīng)而失真。這種測(cè)量技術(shù)也用于實(shí)驗(yàn)室車輛的測(cè)量，在實(shí)驗(yàn)室車輛中，使用原始線束在所謂的電路板結(jié)構(gòu)中復(fù)制完整的電氣/電子系統(tǒng)。
For the analysis of individual consumers or circuits in the test vehicle, automobile manufacturers, development service providers and suppliers often use MULTI-8 measuring modules, a millivoltmeter with 8 parallel, independent inputs. Different probes for current, voltage and temperature measurements can be connected to all inputs. These probes are automatically identified by the measurement module. In order to achieve the highest possible accuracy when calculating the measured value, the calibration value of the respective sample is transferred to the measuring module and used for the calculation. The measurement data is transmitted via CAN and/or Ethernet, a maximum of 8 kHz can be output per channel. A wide range of configuration options enable, for example, the reduction of the data volume via different operating modes and the averaging of measured values.
These modules are preferably installed in the vehicle interior and, for example, looped directly into a circuit via the vehicle fuse box - see Figure 1.
In order to protect the extremely expensive test vehicle against possible short circuits, the measuring circuits are protected by the original vehicle fuse. The arrangement of the measuring shunt in a separate housing ensures that the measured values are not falsified by thermal effects. This measurement technology is also used for measurements on laboratory vehicles, in which the complete electrical/electronic system is reproduced using the original wiring harnesses in a so-called board structure.
數(shù)據(jù)評(píng)估 Evaluation
除了測(cè)量的電流和電壓值之外，通常還會(huì)記錄許多其他測(cè)量數(shù)據(jù)，這些數(shù)據(jù)可以使用商用測(cè)量數(shù)據(jù)軟件進(jìn)行評(píng)估。獨(dú)立于CAN總線的帶有其自身時(shí)間戳的測(cè)量值的傳輸使得測(cè)量值能夠根據(jù)時(shí)間來分配并且與其他測(cè)量數(shù)據(jù)相關(guān)聯(lián)。
由于這種高分辨率測(cè)量技術(shù)，能夠在非常寬的范圍內(nèi)精確測(cè)量電量，即使是最小的耗電大戶也能被識(shí)別出來。由于一輛汽車中有多達(dá)180個(gè)控制單元，這帶來了巨大的優(yōu)化潛力。
Along with the measured current and voltage values, a number of other measurement data are often recorded, which are evaluated using commercially available measurement data software. The transmission of the measured values with its own time stamp, independent of the CAN bus, enables the measured values to be assigned in terms of time and correlated with other measured data.
Thanks to this high-resolution measurement technology, which enables the precise measurement of electrical quantities over a very wide range, even the smallest power guzzlers can be identified. With up to 180 control units in a premium class vehicle, this results in considerable optimization potential.
