Abstract

A vehicle brake system is proposed, which is equipped with a servo pressure supply device (17) and with a master cylinder (1) to which a travel simulator (7) is assigned, by means of which the pedal force travel characteristic is predetermined. This travel simulator (7) can be switched off in order to lose no pedal travel should the servo pressure fail. The travel simulator (7) is switched on and off by a solenoid valve (20), which is connected to an electronic brake unit (11) or a combination of the latter with an electronic antilock control unit (25). At the same time it may be arranged parallel to an antilock multi position valve (12) or separately from this. The vehicle brake system is preferably designed as a hydraulic brake device and is used in passenger motor vehicles. <IMAGE>

Description

FahrzeugbremsanlageVehicle braking system

Stand der Technik Die Erfindung geht aus von einer Fahrzeugbremsarlage nach der Gattung des Hauptanspruchs. Eine derartige Bremsanlage ist bekannt (DE-OS 23 27 508).PRIOR ART The invention is based on a vehicle brake system according to the genre of the main claim. Such a brake system is known (DE-OS 23 27 508).

Bei solchen bekannten Bremsanlagen arbeitet der Geberzylinder (Hauptzylinder) mit einem Wegsimulator zusammen, der die Aufgabe hat, eine bestimmte Pedalkraftwegcharakteristik vorzugeben. Ein solcher Wegsimulator wird, wie bei technisch hochwertigen Systemen bekannt, im Falle der Störung der Servodruckbeschaffung ausgeschaltet, damit keine unnötige Volumenaufnahme erfolgt und damit das vom Geberzylinder verdrängte Volumen in einem solchen Schadensfall noch voll zur Verfügung steht. Dabei wird die Wegsimulator-Ausschaltung mit Ventilen durchgeführt, die entweder vom Speicherdruck der Servoeinrichtung oder vom Steuerdrck des Verstärkers geschaltet werden. Bei solchen Schaltungen gibt es aber Probleme, wenn z.B.In such known brake systems, the master cylinder (master cylinder) works together with a travel simulator, which has the task of defining a certain pedal force travel characteristic to pretend. Such a path simulator is used, as is the case with technically high-quality systems known, switched off in the event of a malfunction of the servo pressure acquisition, so none unnecessary volume uptake takes place and thus the volume displaced by the master cylinder is still fully available in such a case of damage. The path simulator is switched off carried out with valves either from the accumulator pressure of the servo device or can be switched by the control pressure of the amplifier. With such circuits there are but problems if e.g.

Grenzbedingugnen wie Ausfall und/oder Wiederherstellen des Servodruckes während des Bremsvorgangs auftreten.Boundary conditions such as failure and / or restoration of the servo pressure occur during braking.

Vorteile der Erfindung Die Fahrzeugbremsanlage mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß kritische Störungen im System keinen Einfluß mehr haben auf die Ein- oder Ausschaltung des Wegsimulators.Advantages of the invention The vehicle brake system with the characterizing Features of the main claim has the advantage that critical disturbances in the system no longer have any influence on the activation or deactivation of the path simulator.

Gemäß den kennzeichnenden Merkmalen der Unteransprüche wird eine vorteilhafte Wieterbildung der Fahrzeugbremse dadurch erreicht, daß mittels elektronischer Schaltmittel eine Speicherung einer Störung durchgeführt wird.According to the characterizing features of the subclaims, an advantageous one Further formation of the vehicle brake is achieved by means of electronic switching means a fault is saved.

Bei Störung wird der Wegsimulator ausgeschaltet. Auch wenn die Störung in der Zwischenzeit wieder verschwunden ist, wird der Simulator nicht gleich wieder eingeschaltet. Erst wenn nicht gebremst wird, erfolgt seine Wiedereinschaltung. Außer diesem speziellen Fall sind auch noch andere Störfälle denkbar, die mit der Erfindung sicher abgedeckt werden.The path simulator is switched off in the event of a fault. Even if the disorder has disappeared again in the meantime, the simulator will not return immediately switched on. It is only switched on again if there is no braking. In addition to this special case, other incidents are also conceivable, which with the Invention can be safely covered.

Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description.

Beschreibung des Ausführungsbeispiels Eine Fahrzeugbremsanlage hat eipen hydraulischen Hauptzylinder 1-, der als Tandemhauptzylinder ausgebildet ist.Description of the exemplary embodiment Has a vehicle brake system eipen hydraulic master cylinder 1-, which is designed as a tandem master cylinder.

Er wird über ein Bremspedal 2 betätigt und versorgt zwei Bremskreise I und II, deren jedem ein Hauptzylinderkolben 3 und 4 zugeordnet ist.It is operated via a brake pedal 2 and supplies two brake circuits I and II, each of which is assigned a master cylinder piston 3 and 4.

Eine zum Bremskreis 1 gehörende Bremsleitung 5 führt vom Hauptzylinder 1 zu einem Radbremszylinder 6. An diese Bremsleitung 5 ist eine Zweigleitung 19 angeschlossen, die zu einem Wegsimulator 7 führt, der dem Fahrer ein besseres Bremsgefühl vermittelt. Desweiteren ist eine Zweigleitung 8 vorgesehen, die zu einer elektrischen Druckmeßeinrichtung 9 führt, die als elektrischer Druckgeber ausgebildet ist und die über eine Steuerleitung 10 an ein elektronisches Bremsgerät 11 angeschlossen ist.A brake line 5 belonging to the brake circuit 1 leads from the master cylinder 1 to a wheel brake cylinder 6. A branch line 19 is attached to this brake line 5 connected, which leads to a path simulator 7, which gives the driver a better braking feeling conveyed. Furthermore, a branch line 8 is provided, which leads to an electrical Pressure measuring device 9 leads, which is designed as an electrical pressure transmitter and which is connected to an electronic braking device 11 via a control line 10 is.

Die Druckmeßeinrichtung 9 ist mechanisch mit dem Wegsimulator 7 gekoppelt.The pressure measuring device 9 is mechanically coupled to the travel simulator 7.

Hinter dem Anschluß für die Zweigleitung 8 zur Druckmeßeinrichtung 9 ist in die Bremsleitung 5 ein Mehrstellungsventil 12 eingesetzt, das über einen Magneten 13 betätigt vier Stellungen einnehmen kann. Es hat vier Anschlüsse, zwei für die Bremsleitung 5, einen für die Druckseite einer aus Pumpe 14, Speicher 15 und Reservoir 16 bestehenden Servodruckbeschaffungseinrichtung 17 und einen für eine Verbindung zum Reservoir 16. In einer dritten Stellung sind alle Anschlüsse abgeriegelt, und eine vierte Stellung ermöglicht ein Verbinden des Bremszylinders 6 mit dem Reservoir 16. Der Magnet 13 des Mehrstellungsventils 12 wird über eine Leitung 18 vom elektronischen Bremsgerät 11 angesteuert.Behind the connection for the branch line 8 to the pressure measuring device 9, a multi-position valve 12 is used in the brake line 5, which has a Magnet 13 actuated can occupy four positions. It has four connections, two for the brake line 5, one for the pressure side, one from pump 14, memory 15 and reservoir 16 existing servo pressure acquisition device 17 and one for a connection to the reservoir 16. All connections are in a third position locked, and a fourth position enables the brake cylinder to be connected 6 with the reservoir 16. The magnet 13 of the multi-position valve 12 is via a Line 18 controlled by the electronic braking device 11.

Das elektronische Bremsgerät 11 ist über drei Leitungen 22, 23, 24 an ein elektronisches Blockierschutzsteuergerät 25 angeschlossen. Die drei Leitungen 22, 23, 24 liefern die Schaltsignale für den Magneten 13 entsprechend den Stellungen 2, 3 und 4 für Druckerhöhung, Druckhalten und Druckabsenkung des Mehrstellungsventils 12. Schließlich ist noch zu bemerken, daß der Druck im Speicher 15 über einen Schalter 26 und eine Leitung 27 an das elektronische Bremsgerät 11 gemeldet wird und daß ein Stellungsschalter 28 am Bremspedal 2 vorgesehen ist, der über eine Leitung 29 ebenfalls an das Bremsgerät 11 angeschlossen ist.The electronic braking device 11 is via three lines 22, 23, 24 connected to an electronic anti-lock control device 25. The three lines 22, 23, 24 supply the switching signals for the magnet 13 according to the positions 2, 3 and 4 for pressure increase, pressure maintenance and pressure reduction of the multi-position valve 12. Finally, it should be noted that the pressure im Storage 15 to the electronic braking device 11 via a switch 26 and a line 27 is reported and that a position switch 28 is provided on the brake pedal 2, the is also connected to the braking device 11 via a line 29.

In der Zweigleitung 19 zum Wegsimulator 7 ist ein Magnet-Ventil 20 mit einem Magneten 21 angeordnet, mit dem die Verbindung der Bremsleitung 5 zum Wegsimulator 7 entweder herstellbar oder trennbar ist. Bei intakter Anlage ist die Verbindung Bremsleitung 5 - Wegsimulator 7 hergestellt. Der Magnet 21 ist über die Leitung 18 an das Bremsgerät 11 angeschlossen.In the branch line 19 to the path simulator 7 there is a solenoid valve 20 arranged with a magnet 21, with which the connection of the brake line 5 to Path simulator 7 is either producible or separable. If the system is intact, the Connection between brake line 5 and travel simulator 7 established. The magnet 21 is on the Line 18 is connected to the braking device 11.

Wirkungsweise Beim Betätigen des Bremspedals 2 wird im Tandemhauptzylinder 1 für beide Bremskreise I und II ein Druck erzeugt. Der Wegsimulator 7 gewährleistet einen gefühlvollen Druckanstieg. Der in der Bremsleitung 5 entstehende Bremsdruck wird von der Druckmeßeinrichtung 9 an das elektronische Bremsgerät 11 gemeldet, dort verglichen und in Schaltsignale für den Magneten 13 umgewandelt; dabei wird über ebenfalls im Bremsgerät 11 vorgesehene Leistungsendstufen der Magnet 13 des Mehrstellungsventils 12 angesteuert. Das elektronische Bremsgerät 11 empfängt zusätzlich ein Schaltsignal über die Leitung 27 und den Schalter 26, wenn die Servodruckbeschaffungseinrichtung 17 ausfällt. Das elektronische Bremsgerät 11 wirkt mit dem elektronischen Blokkierschutzsteuergerät 25 zusammen, damit das Mehrstellungsventil 12 die Blockierschutzschaltstellungen übermittelt bekommt. Entsprechende Schaltsignale werden dem Blockierschutzsteuergerät 25 von nicht dargestellten Radsensoren zugeleitet.Mode of operation When the brake pedal 2 is depressed, the tandem master cylinder 1 generates a pressure for both brake circuits I and II. The path simulator 7 guarantees a soulful increase in pressure. The brake pressure generated in the brake line 5 is reported by the pressure measuring device 9 to the electronic braking device 11, compared there and converted into switching signals for the magnet 13; thereby will Via power output stages also provided in the braking device 11, the magnet 13 of the Multi-position valve 12 activated. The electronic braking device 11 also receives a switching signal via line 27 and switch 26 when the servo pressure supply device 17 fails. The electronic braking device 11 works with the electronic anti-lock control device 25 together so that the multi-position valve 12 has the anti-lock switch positions gets transmitted. Corresponding switching signals are sent to the anti-lock control device 25 supplied from wheel sensors, not shown.

Es ist zu erkennen, daß das Mehrstellungsventil 12 samt Elektronik sowohl für die Bremskraftverstärkung als auch für die Blockierschutzfunktion verwendet ist. Bei intakter Einrichtung dient der Hauptzylinderdruck nur als Steuerdruck. Die Druckeinspeisung zum Bremszylinder erfolgt nach elektronischem Druckvergleich der beiden Drücke vor und hinter dem Mehrstellungsventil 12, eventuell gekuppelt mit dem Signal vom Pedalstellungs-Schalter 28. Entsprechend der gewünschten Verstärkung wird das Signal der Druckmeßeinrichtung 9 verstärkt.It can be seen that the multi-position valve 12 including electronics used both for the brake force boost and for the anti-lock function is. If the device is intact, the master cylinder pressure is only used as a control pressure. The pressure feed to the brake cylinder takes place after an electronic pressure comparison of the two pressures upstream and downstream of the multi-position valve 12, possibly coupled with the signal from the pedal position switch 28. According to the desired gain the signal of the pressure measuring device 9 is amplified.

Der Steuerdruck vom Haupt zylinder 1 bewirkt über die Elektronik die Ansteuerung des Magneten 13 des M1irstellungsventils 12, das von der Servodruckbeschaffungseinrichtung 17 so lange Druck zum Radbremszylinder 6 einspeist, bis dort der gewünschte Bremsdruck erreicht ist. Bei einer Reduzierung des Steuerdrucks vom Hauptzylinder 1 aus geht das Mehrstellungsventil 12 in seine vierte Stellung, in der es den Radzylinder-Bremsdruck reduziert.The control pressure from the master cylinder 1 causes the electronics to Activation of the magnet 13 of the setting valve 12, which is provided by the servo pressure supply device 17 feeds pressure to the wheel brake cylinder 6 until there is the desired brake pressure is reached. When the control pressure is reduced from the master cylinder 1 the multi-position valve 12 in its fourth position, in which it the wheel cylinder brake pressure reduced.

Bei Störung der Servodruckbeschaffungseinrichtung 17 versorgt der Tandem-Hauptzylinder in gewöhnlicher Weise die Bremskreise I und II. Dabei wird aber der Wegsimulator 7 von der Bremsleitung 5 über das Magnetventil 20 getrennt.In the event of a fault in the servo pressure acquisition device 17, the supplies Tandem master cylinder in the usual way the brake circuits I and II but the travel simulator 7 is separated from the brake line 5 via the solenoid valve 20.

Auf diese Weise wird dann mittels elektronischer Schaltmittel im Bremsgerät 11 und im Blockierschutzsteuergerät 25 der Wegsimulator 7 blockiert. Die Störung wird elektronisch gespeichert und selbst wenn sie mittlerweise verschwunden ist, wird die BLockierung des Simulators 7 erst wieder entriegelt, wenn z.B. nicht gebremst wird.In this way, electronic switching means in the braking device 11 and the path simulator 7 blocked in the anti-lock control device 25. The disorder is stored electronically and even if it has disappeared in the meantime, the BLocking of the simulator 7 is only unlocked again if, for example, there is no braking will.

Dazu kommt, daß Systeme mit elektronischer Verstärkung eine solche Blockiermöglichkeit des Wegsimulators 7 benötigen, da unabhängige Störungen in der elektronischen Ansteuerung des Stellgliedes für die elektronische Verstärkung oder der Energieversorgung vorliegen können. Ist z.B. die Energieversorugng intakt und die Überwachungsschaltung für die elektronische Verstärkung erkennt eine Störung in der Ansteuerung des Mehrstellungsventils 12, so wird das System abgeschaltet. Der Hauptzylinder 1 liefert dann eine Notfunktion, der Wegsimulator 7 wird abgeschaltet, damit kein Druckmittel nutzlos verdrängt wird.In addition, systems with electronic amplification are such Need to block the path simulator 7, as independent disturbances in the electronic control of the actuator for the electronic amplification or the energy supply can be present. For example, is the energy supply intact and the monitoring circuit for the electronic amplification detects a malfunction in the control of the multi-position valve 12, the system is switched off. The master cylinder 1 then provides an emergency function, the path simulator 7 is switched off, so that no pressure medium is uselessly displaced.

In der Zeichnung ist eine Bauart dargestellt, bei der die beiden Magnete 13 und 21 des Mehrstellungsventils 12 und des Magnetventils 20 parallel über die Leitung 18 angesteuert werden. Es ist aber auch möglich, sie getrennt anzusteuern.In the drawing, a design is shown in which the two magnets 13 and 21 of the multi-position valve 12 and the solenoid valve 20 in parallel via the Line 18 can be controlled. But it is also possible to control them separately.

Außerdem ist zu bemerken, daß das Magnetventil 20 auch mit einem Rastmagneten 21' versehen sein kann, der mit einem Kolben 7' des Wegsimulators 7 zusammenarbeitet.It should also be noted that the solenoid valve 20 is also provided with a detent magnet 21 'can be provided, which cooperates with a piston 7' of the travel simulator 7.

Eine derartige ausbildung ist einfacher, sie ist in der Zeichnung gestrichelt dargestellt.Such a training is easier, it is in the drawing shown in dashed lines.
