Achsmodulator) noch eine verlässliche Verzögerung/Abbremsung des damit ausgestatteten Fahrzeugs gewährleistet ist. Die vorliegende Erfindung trägt somit erheblich zur Steigerung eines Sicherheitsstandards des jeweiligen mit dem entsprechenden elektro-pneumatischen Bremssystem ausgestatteten Fahrzeugs bei. Außerdem schafft die vorliegende Erfindung eine vorteilhafte Aufteilung von (herkömmlichen) elektro-pneumatischen Advantages of the invention The present invention provides electro-pneumatic brake systems, by means of which even in the event of failure of one of several (here two) electrical power supply device or a component of the brake system (eg. Axle modulator) is still a reliable deceleration / deceleration of the vehicle equipped with it guaranteed. The present invention thus contributes significantly to the enhancement of a safety standard of the respective vehicle equipped with the corresponding electro-pneumatic brake system. In addition, the present invention provides an advantageous distribution of (conventional) electro-pneumatic
Bremssystemkomponenten auf unabhängige Energieversorgungsvorrichtungen. Brake system components on independent power supply devices.
In einer vorteilhaften Ausführungsform des elektro-pneumatischen In an advantageous embodiment of the electro-pneumatic
Bremssystems ist die mindestens eine erste Modulationskomponente des ersten Bremskreises elektrisch an der ersten elektrischen Brake system, the at least one first modulation component of the first brake circuit is electrically connected to the first electrical
Energieversorgungsvorrichtung angebunden und die mindestens eine zweite Modulationskomponente des zweiten Bremskreises ist elektrisch an der zweiten elektrischen Energieversorgungsvorrichtung angebunden. Man kann dies auch damit umschreiben, dass bei diesem elektro-pneumatischen Bremssystem die Modulationskomponenten Achsmodulatoren mittels voneinander unabhängiger elektrischer Energieversorgungsvorrichtungen mit Energie versorgt werden. Deshalb ist an diesem elektro-pneumatischen Bremssystem redundante Energieversorgung geschaffen, weshalb das elektro-pneumatische Bremssystem eine im Vergleich mit dem Stand der Technik verbesserte Rückfallebene aufweist.  Power supply device attached and the at least one second modulation component of the second brake circuit is electrically connected to the second electrical power supply device. One can also rewrite this with the fact that in this electro-pneumatic brake system, the modulation components axle modulators are powered by means of independent electrical power supply devices with energy. Therefore, redundant power supply is provided to this electro-pneumatic brake system, which is why the electro-pneumatic brake system has an improved fallback level in comparison with the prior art.
Optionaler Weise kann auch die elektronische Parkbremse elektrisch an der zweiten elektrischen Energieversorgungsvorrichtung angebunden sein.

Energieversorgungsvorrichtung angebunden. Optionaler Weise kann eine zweite Steuervorrichtung, mittels welcher die mindestens eine zweite Modulationskomponente des zweiten Bremskreises ansteuerbar ist, elektrisch an der zweiten elektrischen Energieversorgungsvorrichtung angebunden sein. Liegt eine derartige elektrische Architektur an dem elektro-pneumatischen Power supply device connected. Optionally, a second Control device, by means of which the at least one second modulation component of the second brake circuit can be controlled, be electrically connected to the second electrical power supply device.

Somit kann die erste Steuervorrichtung im Normalfall (d.h. vor einem Ausfall/einer Beeinträchtigung einer der elektrischen Energieversorgungsvorrichtungen) sowohl die mindestens eine erste Modulationskomponente des ersten Brake system before, it is advantageous if the first control device, a master status and the second control device is assigned a slave status, wherein the at least one second modulation component of the second brake circuit can also be controlled by means of the first control device. Thus, in the normal case (i.e., prior to failure / impairment of any of the electric power supply devices), the first control device may receive both the at least one first modulation component of the first
Bremskreises als auch die mindestens eine zweite Modulationskomponente des zweiten Bremskreises ansteuern, und damit leicht Funktionsweisen aller Control the brake circuit and the at least one second modulation component of the second brake circuit, and thus easily functioning of all

Energieversorgungsvorrichtung die zweite Steuervorrichtung und die mindestens eine zweite Modulationskomponente des zweiten Bremskreises noch zum verlässlichen Verlangsamen/Abbremsen des Fahrzeugs eingesetzt werden. Außerdem können bei einem Ausfall/einer Beeinträchtigung der zweiten elektrischen Energieversorgungsvorrichtung noch die erste Steuervorrichtung und die mindestens eine erste Modulationskomponente des ersten Bremskreises ein Verlangsamen/Abbremsen des Fahrzeugs verlässlich bewirken.  Power supply device, the second control device and the at least one second modulation component of the second brake circuit are still used for reliable deceleration / deceleration of the vehicle. In addition, in case of failure / impairment of the second electric power supply device, the first control device and the at least one first modulation component of the first brake circuit can reliably effect deceleration / deceleration of the vehicle.
In einer weiteren vorteilhaften Ausführungsform des elektro-pneumatischen Bremssystems sind die mindestens eine erste Modulationskomponente des ersten Bremskreises und die mindestens eine zweite Modulationskomponente des zweiten Bremskreises elektrisch an der ersten elektrischen In a further advantageous embodiment of the electro-pneumatic brake system, the at least one first modulation component of the first brake circuit and the at least one second modulation component of the second brake circuit are electrically connected to the first electrical
Energieversorgungsvorrichtung angebunden und die elektronische Parkbremse ist elektrisch an der zweiten elektrischen Energieversorgungsvorrichtung angebunden. Ein Ausfall/eine Beeinträchtigung der ersten elektrischen Power supply device attached and the electronic parking brake is electrically connected to the second electrical power supply device.

Bei einem Ausfall/einer Beeinträchtigung der ersten elektrischen In this case, it is advantageous if a control device of the electro-pneumatic brake system, by means of which the at least one first modulation component of the first brake circuit and the at least one second modulation component of the second brake circuit can be controlled, is electrically connected to the first electrical power supply device. In case of failure / impairment of the first electrical
Energieversorgungsvorrichtung kann das Fahrzeug in diesem Fall noch mittels der elektronischen Parkbremse verlangsamt/abgebremst werden. Gleichzeitig ist das Fahrzeug bei einem Ausfall/einer Beeinträchtigung der zweiten elektrischen Energieversorgungsvorrichtung mittels aller Radbremszylinder des ersten Bremskreises und des zweiten Bremskreises unter zusätzlicher Ausnutzung der Steuervorrichtung verlangsambar/abbremsbar. Power supply device, the vehicle can still be slowed down / decelerated in this case by means of the electronic parking brake. At the same time, if the second electric power supply device fails or is impaired by means of all the wheel brake cylinders of the first brake circuit and the second brake circuit, the vehicle can be slowed down / braked with additional use of the control device.

Vorzugsweise sind alle erste Modulationskomponenten 10 des ersten Power supply device 14, to which at least the at least one first modulation component 10 of the first brake circuit (directly or indirectly) is electrically connected. The electrical connection of the at least one first modulation component 10 of the first brake circuit to the first electrical power supply device 14 is implemented such that at least the at least one first modulation component 10 of the first brake circuit can be supplied with power by means of the first power supply device 14. Preferably, all first modulation components 10 of the first
Bremskreises an der ersten elektrischen Energieversorgungsvorrichtung 14 elektrisch angebunden. Damit kann auch eine Bestromung aller erster  Brake circuit to the first electric power supply device 14 electrically connected. This can also be an energization of all first

Bevorzugter Weise sind alle zweite Modulationskomponenten 12 des ersten Bremskreises an der zweiten elektrischen EnergieversorgungsvorrichtungIn addition, the electro-pneumatic brake system also has a second electrical power supply device 16, to which the at least one second modulation component 12 of the second brake circuit is electrically connected (directly or indirectly). This electrical connection of the at least one second modulation component 12 of the second brake circuit to the second electrical energy supply device 16 is created so that a current flow from the second electrical energy supply device 16 to the at least one second modulation component 12 of the second brake circuit is possible.

Außerdem kann selbst bei einem kompletten Ausfall der ersten elektrischen Energieversorgungsvorrichtung 14 mittels der zweiten elektrischen Modulation component 10 of the first brake circuit advantageously control.

Hierzu kann eine vorab festgelegte Bremstrajektorie, welche selbst bei einem kompletten Ausfall der zentralen Steuervorrichtung 18 noch ausführbar ist, für den zweiten Bremskreis hinterlegt sein. In einer alternativen Ausführungsform kann das elektro-pneumatische Modulation component 12 of the second brake circuit an automatic braking of the vehicle are still running. For this purpose, a predetermined braking trajectory, which is still executable even in the event of complete failure of the central control device 18, can be stored for the second brake circuit.

Der ersten Steuervorrichtung, mittels welcher sowohl die mindestens eine erste Modulationskomponente 10 des ersten Bremskreises als auch die mindestens eine zweite Modulationskomponente 12 des zweiten Bremskreises ansteuerbar sind, kann ein Master-Status (gegenüber der zweiten Steuervorrichtung) zugeordnet sein. Demgegenüber kann der zweiten Have control device. The first control device, by means of which both the at least one first modulation component 10 of the first brake circuit and the at least one second modulation component 12 of the second brake circuit can be controlled, may be assigned a master status (in relation to the second control device). In contrast, the second
Steuervorrichtung, mittels welcher zumindest die mindestens eine zweite Modulationskomponente 12 des zweiten Bremskreises ansteuerbar ist, ein Slave-Status (gegenüber der ersten Steuervorrichtung) zugeordnet sein. Auch mittels einer derartigen Steuerung des elektro-pneumatischen Bremssystems können hinterlegte Bremstrajektorien bei einem Ausfall einer der beiden Control device, by means of which at least the at least one second modulation component 12 of the second brake circuit can be controlled, a slave status (compared to the first control device) to be assigned. Also by means of such a control of the electro-pneumatic brake system deposited brake trajectories in case of failure of one of the two
Energieversorgungsvorrichtungen 14 und 16 zum Ausführen einer automatischen Bremsung genutzt werden. Power supply devices 14 and 16 are used to perform an automatic braking.
In einer möglichen Weiterbildung des elektro-pneumatischen Bremssystems der Fig. 1 kann noch eine (nicht skizzierte) elektronische Parkbremse elektrisch an der ersten elektrischen Energieversorgungsvorrichtung 14 und/oder an der zweiten elektrischen Energieversorgungsvorrichtung 16 angebunden sein. In diesem Fall kann bei einer Beeinträchtigung/einem Ausfall einer der beiden elektrischen Energieversorgungsvorrichtungen 14 oder 16 auch die elektronische Parkbremse zusätzlich zum Verlangsamen/Abbremsen des Fahrzeugs eingesetzt werden. Wie anhand von Fig. 1 jedoch erkennbar ist, ist eine In one possible development of the electro-pneumatic brake system of FIG. 1, an electronic parking brake (not shown) may be electrically connected to the first electric power supply device 14 and / or to the second electric power supply device 16. In this case, in case of deterioration / failure of either of the two electric power supply devices 14 or 16, the electronic parking brake may be used in addition to decelerating / decelerating the vehicle. However, as can be seen from Fig. 1, is a
Ausstattung des elektro-pneumatischen Bremssystems mit der elektronischen Parkbremse optional. Equipment of the electro-pneumatic brake system with the electronic parking brake optional.
Fig. 2 zeigt eine schematische Schaltungsstruktur zum Erläutern einer zweiten Ausführungsform des elektro-pneumatischen Bremssystems. Fig. 2 shows a schematic circuit structure for explaining a second embodiment of the electro-pneumatic brake system.
Bei dem elektro-pneumatischen Bremssystem der Fig. 2 sind sowohl die mindestens eine erste Modulationskomponente 10 des ersten Bremskreises als auch die mindestens eine zweite Modulationskomponente 12 des zweiten Bremskreises (direkt oder indirekt) an der ersten elektrischen In the electro-pneumatic brake system of FIG. 2, both the at least one first modulation component 10 of the first brake circuit as also the at least one second modulation component 12 of the second brake circuit (directly or indirectly) at the first electrical
Energieversorgungsvorrichtung 14 elektrisch angebunden. Diese elektrische Anbindung der Modulationskomponenten 12 und 14 beider Bremskreise an die erste elektrische Energieversorgungsvorrichtung 14 ist so geschaffen, dass ein Stromfluss von der ersten elektrischen Energieversorgungsvorrichtung 14 an (alle) Modulationskomponenten 12 und 14 beider Bremskreise möglich ist. Power supply device 14 electrically connected. This electrical connection of the modulation components 12 and 14 of both brake circuits to the first electrical power supply device 14 is created so that a flow of current from the first electrical power supply device 14 to (all) modulation components 12 and 14 of both brake circuits is possible.
Das elektro-pneumatischen Bremssystem der Fig. 2 hat auch eine elektronische Parkbremse 22. Unter der elektronischen Parkbremse 22 ist eine elektrische Vorrichtung zu verstehen, mittels welcher ein Wegrollen des The electro-pneumatic brake system of Fig. 2 also has an electronic parking brake 22. The electronic parking brake 22 is an electrical device to understand, by means of which a rolling of the
Fahrzeugs/Kraftfahrzeugs zuverlässig verhinderbar ist. Beispielsweise wirkt ein (mittels eines Handbremsventils der elektronischen Parkbremse 22) bewirkter pneumatischer Druck auf die Hinterachse des Fahrzeugs dem unerwünschten Wegrollen des Fahrzeugs/Kraftfahrzeugs entgegen. Wahlweise kann die elektronische Parkbremse 22 (z.B. mittels eines Tastendrucks) manuell aktivierbar sein oder für eine automatische Aktivierung (insbesondere sobald ein Motor des Fahrzeugs/Kraftfahrzeugs ausgeschaltet ist) ausgelegt sein. Vehicle / motor vehicle is reliably prevented. For example, a pneumatic pressure applied to the rear axle of the vehicle (by means of a manual brake valve of the electronic parking brake 22) counteracts the undesirable rolling away of the vehicle / motor vehicle. Optionally, the electronic parking brake 22 may be manually activated (e.g., by a keystroke) or may be configured for automatic activation (particularly once an engine of the vehicle / motor vehicle is turned off).
Vorteilhafterweise ist bei dem elektro-pneumatischen Bremssystem der Fig. 2 die elektronische Parkbremse 22 an der zweiten elektrischen Advantageously, in the electro-pneumatic brake system of FIG. 2, the electronic parking brake 22 on the second electrical
Energieversorgungsvorrichtung 16 (direkt oder indirekt) elektrisch angebunden. Selbst bei einer Beeinträchtigung/einem Ausfall der ersten elektrischen Power supply device 16 (directly or indirectly) electrically connected. Even if there is an impairment / failure of the first electrical
Energieversorgungsvorrichtung 14 ist somit eine Bestromung der elektronischen Parkbremse 22 mittels der zweiten elektrischen Energieversorgungsvorrichtung 16 noch möglich. Deshalb kann die elektronische Parkbremse 22 selbst bei einem kompletten Ausfall der ersten elektrischen Energieversorgungsvorrichtung 14 noch kontrolliert eine (automatische) Bremsung des Fahrzeugs/Kraftfahrzeugs einleiten. In der Regel ist eine Intelligenz/Ansteuerlogik der elektronischen Parkbremse 22 in einem eigenen Steuergerät der elektronischen Parkbremse 22 hinterlegt. Eine Anpassung der Intelligenz/Ansteuerlogik der elektronischen Parkbremse 22 zum Bewirken der (automatischen) Bremsung des Power supply device 14 is thus an energization of the electronic parking brake 22 by means of the second electrical power supply device 16 is still possible. Therefore, the electronic parking brake 22 even under a complete failure of the first electric power supply device 14 still controlled (automatic) braking of the vehicle / motor vehicle initiate. As a rule, an intelligence / control logic of the electronic parking brake 22 is stored in a separate control unit of the electronic parking brake 22. An adaptation of the intelligence / control logic of the electronic parking brake 22 to effect the (automatic) braking of the
Fahrzeugs/Kraftfahrzeugs bei einer Beeinträchtigung/ einem Ausfall der ersten elektrischen Energieversorgungsvorrichtung 14 ist bei dem elektro- pneumatischen Bremssystem der Fig. 2 damit leicht umsetzbar. In der Ausführungsform der Fig. 2 ist beispielhaft eine zentrale Steuervorrichtung 18 des elektro-pneumatischen Bremssystems, mittels welcher die mindestens eine erste Modulationskomponente 10 des ersten Bremskreises und die mindestens eine zweite Modulationskomponente 12 des zweiten Bremskreises ansteuerbar sind, elektrisch an der ersten elektrischen Vehicle / motor vehicle in the event of impairment / failure of the first electric power supply device 14 is thus easily implementable in the electro-pneumatic brake system of FIG. 2. In the embodiment of FIG. 2, by way of example, a central control device 18 of the electro-pneumatic brake system, by means of which the at least one first modulation component 10 of the first brake circuit and the at least one second modulation component 12 of the second brake circuit can be controlled, electrically to the first electrical
Energieversorgungsvorrichtung 14 angebunden. Es ist völlig ausreichend, die elektronische Handbremse 22 nur über einen Fahrzeugbus 20 (z.B. einen CAN oder einen LIN) mit der zentralen Steuervorrichtung 18 zu verbinden. Selbst bei einem kompletten Ausfall der zentralen Steuervorrichtung 18 ist aufgrund der unabhängigen Versorgung der elektronischen Parkbremse 22 mit Strom noch eine Rückfallebene für einen sicheren Halt des Fahrzeugs gewährleistet. Power supply device 14 connected. It is quite sufficient to connect the electronic handbrake 22 to the central control device 18 only via a vehicle bus 20 (e.g., a CAN or a LIN). Even with a complete failure of the central control device 18 is due to the independent supply of the electronic parking brake 22 with power still a fallback level for a secure fit of the vehicle guaranteed.
