Description

本発明は、車両用電空制動制御装置、及び２つの車軸制動圧力調整器の間のデータ伝送回線を監視する方法に関する。  The present invention relates to an electropneumatic braking control device for a vehicle and a method for monitoring a data transmission line between two axle braking pressure regulators.

商用車両の電空制動制御装置は、データバスを介して互いに組合わされる複数の制御器を持っている。特に制動圧力調整器は異なる車軸に対して設けられ、中央モジュールと通信し、場合によっては互いに通信する。データバスのために一部では星形カッドケーブルが使用され、アース導線及び供給電圧導線が両方のデータ導線又は信号導線を包囲するか、又は互いに撚られている。この場合アース導線は遮蔽のため外側に延びている。  The electropneumatic braking control device for a commercial vehicle has a plurality of controllers combined with each other via a data bus. In particular, the braking pressure regulator is provided for different axles and communicates with the central module and possibly also with each other. A star quad cable is used in part for the data bus, and the ground conductor and the supply voltage conductor surround both data or signal conductors or are twisted together. In this case, the ground wire extends outward for shielding.

この場合データ伝送回線は故障し易い。特に車両の外側に延びるか又は環境の影響を受けるデータ伝送回線は、電磁放射の影響を受けるか、又は機械的にも損傷される。車両配線にあって信号分配に用いられる相互接続プラグ装置も、同様に故障し易い。  In this case, the data transmission line is prone to failure. In particular, data transmission lines that extend outside the vehicle or are affected by the environment are affected by electromagnetic radiation or are also mechanically damaged. The interconnection plug device used for signal distribution in the vehicle wiring is also prone to failure as well.

すべての導線の完全な検査は、一般に費用がかかる。従ってデータ伝送回線の一部は、伝送欠陥が生じた場合にのみ、信頼できないものと認められる。  A complete inspection of all conductors is generally expensive. Therefore, a part of the data transmission line is recognized as unreliable only when a transmission defect occurs.

複数の制御器を持つ電子システムにある多重アース導線では、アース導線特に高速データ伝送区間の導線破断の識別は殆ど不可能である。しかも原則的に、関係する導線の電位を読取ることができる。しかし一般に機器供給用のアース導線がまだ存在するので、この値又はこのような検査から、欠陥のある接触を識別することはまだできない。  With multiple earth conductors in electronic systems with multiple controllers, it is almost impossible to identify conductor breaks in the earth conductor, particularly in high speed data transmission sections. Moreover, in principle, the potential of the relevant conductor can be read. However, since there is generally still a ground wire for equipment supply, it is not yet possible to identify defective contacts from this value or from such an inspection.

アース導線により形成されるデータケーブルの遮蔽アースが裂ける際、特に高周波伝送区間では、電磁不整合が起こる可能性がある。  When the shield ground of the data cable formed by the ground conductor is torn, electromagnetic mismatch may occur, particularly in a high-frequency transmission section.

本発明の基礎になっている課題は、比較的少ない費用で高い安全性又は良好な監視を可能にする電空制動制御装置及びデータ伝送回線の監視方法を提供することである。  The problem underlying the present invention is to provide an electropneumatic braking control device and a data transmission line monitoring method that enable high safety or good monitoring at a relatively low cost.

この課題は、請求項１に記載の制動制御装置及び請求項１５に記載の方法によって解決される。従属請求項は好ましい展開を記載している。この場合特に本発明による電空制動制御装置を持つ商用車両が考慮されている。  This problem is solved by the braking control device according to claim 1 and the method according to claim 15. The dependent claims describe preferred developments. In this case, in particular, commercial vehicles having an electropneumatic braking control device according to the invention are considered.

従って本発明に撚れば、車軸制動圧力調整器の間のデータ伝送回線にある少なくとも１つのアース導線が、起こり得る欠陥を監視される。この場合本発明によれば、特にこの分散データ伝送回線が傷つき易いことがわかる。なぜならば、このデータ伝送回線の一部は車両の外側に延びていることがあるので、遮蔽に役立つそのアース導線が環境の影響及び機械的負荷を受けるからである。  Thus, according to the present invention, at least one earth conductor in the data transmission line between the axle braking pressure regulators is monitored for possible defects. In this case, according to the present invention, it can be seen that this distributed data transmission line is particularly easily damaged. This is because part of this data transmission line may extend outside the vehicle, so that its grounding conductor, which serves as a shield, is subject to environmental influences and mechanical loads.

この場合このデータ伝送回線のために、４導体導線特に星形カッドケーブルが有利に使用され、通常アース導線、供給電圧導線及び２つのデータ導線を含んでいる。この場合供給電圧導線はアースに置かれるので、本発明によれば２つのアース導線が遮蔽に役立ち、データ導線又は信号導線の周りに設けられ、例えば編み線又は巻き線として撚られる。  In this case, for this data transmission line, a four conductor conductor, in particular a star quad cable, is advantageously used, usually including a ground conductor, a supply voltage conductor and two data conductors. In this case, since the supply voltage conductor is placed at ground, according to the invention, two earth conductors serve for shielding and are provided around the data or signal conductors, for example twisted as knitted or wound wires.

従って本発明によれば、制動圧力調整器の間の分散データ伝送回線のこれらのアース導線の動作能力を検査する検査回路装置の使用が提案され、その際検査回路装置の送信装置がアース導線へ検査信号を送出し、他方の制動圧力調整器に設けられる受信装置がこれらの検査信号を読出し、続いて評価するか又は評価装置へ送る。  Therefore, according to the present invention, it is proposed to use an inspection circuit device for inspecting the operating capacity of these earth conductors of the distributed data transmission line between the braking pressure regulators, in which case the transmitter of the inspection circuit device is connected to the earth conductor. Sending inspection signals, a receiving device provided on the other braking pressure regulator reads these inspection signals and subsequently evaluates them or sends them to the evaluation device.

検査信号は特にミリ秒範囲即ち１ｋＨｚの範囲又はそれ以下の所にあり、従って伝送されるデータに関して低周波である。直流電位が存在していてもよい。  The test signal is in particular in the millisecond range, i.e. in the range of 1 kHz or below, and is therefore low frequency with respect to the transmitted data. A direct current potential may be present.

本発明によれば、検査回路装置は制動圧力調整器のデータバス駆動回路に直接設けられる。この場合一体の送信装置及び受信装置を複数の制動圧力調整器に設けることができ、従ってそれぞれ１つのアース導線又はアースに置かれる供給電圧導線を検査することができる。  According to the invention, the inspection circuit device is provided directly in the data bus drive circuit of the braking pressure regulator. In this case, an integral transmitter and receiver can be provided in a plurality of braking pressure regulators, so that it is possible to inspect one earth conductor or the supply voltage conductor placed on earth, respectively.

検査回路は所定の低周波インピーダンス及びアース導線の遮蔽機能に合わされる高周波インピーダンスを持つ検査電圧を、データインタフェースの信号アース導線へ送出する。目標装置の受信装置において、アース導線が所定の入力インピーダンスへ導かれ、入力レベルが検査される。  The test circuit sends a test voltage having a predetermined low frequency impedance and a high frequency impedance adapted to the shielding function of the ground conductor to the signal ground conductor of the data interface. In the receiving device of the target device, the ground conductor is led to a predetermined input impedance and the input level is checked.

インピーダンスの設計は、例えば分路インピーダンスが配線又は供給個所における湿気によって監視レベルの誤励起を生じないように、選ばれる。  The impedance design is chosen, for example, so that the shunt impedance does not cause monitoring level misexcitation due to moisture in the wiring or supply location.

The braking pressure regulators 3 and 4 are provided with second bus drive circuits 3-2 and 4-2 for the distributed data transmission line 14. In this case, both outer conductors 14a, 14b are interchangeably connected to the terminals of both modules 3, 4 and both are placed at signal ground. These outer conductors are used to shield both the inner data conductors 14c, 14d and are provided around the data conductors 14c, 14d as a knitted or wound wire.
