Abstract

The invention relates to a brake system for motor vehicles that can be actuated in a "brake-by-wire" operating mode both by the vehicle driver and independently of the vehicle driver, and that is operated preferably in the "brake-by-wire" operating mode, and that can be operated in at least one fallback operating mode wherein only operation by the vehicle driver is possible. The brake system comprises an electrohydraulic pressure generating device (5) outputting a brake system pressure, and a pressure modulation unit comprising one inlet value (6a - 6d) and one outlet valve (7a - 7d) per wheel brake (8, 9, 10, 11), tapped from the brake system pressure, wherein the inlet and outlet valves (6a - 6d, 7a - 7d) output or pass along the brake system pressure in the non-actuated state. In order to prevent irritations to the driver of the vehicle, particularly if the electrical on-board network of the motor vehicle fails, according to the invention, circular electrically actuated switching valves (37, 47) are connected between the pressure generating device (5) and the pressure modulation unit, said valve producing a hydraulic connection between the pressure generating device (5) and the pressure modulation unit in an actuated state.

Eine derartige Bremsanlage ist aus der EP 1 950 112 AI be¬ kannt. Als ein gravierender Nachteil der vorbekannten Brems anläge wird die Tatsache empfunden, dass bei einem Ausfall des elektrischen Antriebs der elektrohydraulischen Druckbereitstellungseinrichtung während eines Bremsvorgangs ein Zu rücksteilen deren Kolben eine erhebliche Verlängerung des Bremspedalweges zur Folge hat, die vom Fahrzeugführer als Bremsversagen wahrgenommen wird. Such a brake system is known from EP 1 950 112 AI ¬ known. As a serious drawback of the known brake anläge the fact is felt that in case of failure of the electric drive of the electrohydraulic pressure supply device during a braking process to back down the piston has a significant extension of the brake pedal travel result, which is perceived by the driver as brake failure.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Brems anläge der eingangs genannten Art dahingehend zu verbessern dass der Fahrzeugführer selbst bei einem Ausfall des elekt¬ rischen Bordnetzes des damit ausgerüsteten Kraftfahrzeuges nicht irritiert wird. It is therefore an object of the present invention to improve a brake Anläge of the type mentioned in that the driver is not irritated even in the event of a failure of the elekt ¬ cal electrical system of the vehicle equipped with it.

Die Eingangsanschlüsse der Einlassventile 6a-6d werden mittels Systemdruckleitungen 13a, 13b mit einem Druck versorgt, der als Systemdruck bezeichnet wird, wobei Drucksensoren 39, 49 zum Erfassen der in den Systemdruckleitungen 13a, 13b herrschenden Drücke vorgesehen sind. Rücklaufleitungen 14a, 14b, die an die Ausgangsanschlüsse der Auslassventile 7a-7d angeschlossen sind, verbinden die Aus¬ lassventile 7a-7d mit dem drucklosen Druckmittelvorratsbe¬ hälter 4.

Wie der Zeichnung weiterhin zu entnehmen ist, weist die hydraulische Kolben-Zylinderanordnung 2, die als eine Betäti¬ gungseinheit der erfindungsgemäßen Bremsanlage angesehen werden kann, in einem (Hauptbremszylinder-) Gehäuse 21 zwei hintereinander angeordnete hydraulische Kolben 15, 16 auf, die hydraulische Kammern bzw. Druckräume 17, 18 begrenzen, die zusammen mit den Kolben 15, 16 einen zweikreisigen As the drawing continues to show, the hydraulic piston-cylinder assembly 2, which can be regarded as an Actu ¬ supply unit of the brake system according to the invention in a (master cylinder) housing 21 two successively arranged hydraulic piston 15, 16, the hydraulic chambers or to limit pressure chambers 17, 18, the together with the piston 15, 16 a zweikreisigen
Hauptbremszylinder bzw. einen Tandemhauptzylinder bilden. Die Druckräume 17, 18 stehen einerseits über in den Kolben 15, 16 ausgebildete radiale Bohrungen 19, 20 mit dem Druck¬ mittelvorratsbehälter 4 in Verbindung, wobei diese durch eine Relativbewegung der Kolben 17, 18 im Gehäuse 21 absperrbar sind, und andererseits mittels hydraulischer Leitungen 22a, 22b mit den vorhin erwähnten Systemdruckleitungen 13a, 13b, in Verbindung, an die Eingangsanschlüsse der vorhin erwähnten Druckmodulations- bzw. Einlassventile 6a-6d ange¬ schlossen sind. In den hydraulischen Leitungen 22a, 22b sind je ein Trennventil 23a, 23b eingefügt, die als ein elekt¬ risch betätigbare, vorzugsweise stromlos offenes (SO-) 2/2- Wegeventile ausgebildet sind. Ein an den Druckraum 17 ange¬ schlossener Drucksensor 24 erfasst den im Druckraum 17 durch ein Verschieben des ersten Kolbens 15 aufgebauten Druck. Außerdem nehmen die Druckräume 17, 18 nicht näher bezeichnete Rückstellfedern auf, die die Kolben 15, 16 entgegen der Betätigungsrichtung vorspannen. Eine am Bremspedal 1 angekoppelte Kolbenstange 25 wirkt dabei mit dem ersten (Hauptzy¬ linder- ) Kolben 15 zusammen, wobei der Betätigungsweg des Bremspedals 1 von einem vorzugsweise redundant ausgeführten Wegsensor 26 erfasst wird.

A coupled to the brake pedal 1 piston rod 25 acts together with the first (Hauptzy ¬ linder-) piston 15, wherein the actuation of the brake pedal 1 is detected by a preferably redundantly designed displacement sensor 26.
Außerdem ist aus der zeichnerischen Darstellung der erfindungsgemäßen Bremsanlage ersichtlich, dass die vorhin genannte Wegsimulatoreinrichtung 3 hydraulisch ausgeführt ist und im Wesentlichen aus einer Simulatorkammer 27, einer Simulatorfederkammer 28 sowie einem die beiden Kammern 27, 28 voneinander trennenden Simulatorkolben 29 besteht.

Der erste Kolben 33 begrenzt einen ers¬ ten Druckraum 34, während ein in der Betätigungsrichtung dem ersten Kolben 33 nachgeschalteter zweiter Kolben 43 einen zweiten hydraulischen Druckraum 44 begrenzt. Ähnlich wie bei dem oben beschriebenen Hauptbremszylinder 2 stehen die beiden Druckräume 34, 44 einerseits über in den Kolben 33, 43 ausgebildete radiale Öffnungen 35, 45 bzw. zu den radialen Bohrungen 19, 20 der Hauptzylinderkolben 15, 16 führende Leitungsabschnitte 36, 46 mit dem Druckmittelvorratsbehälter 4 in Verbindung und sind andererseits durch Öffnen von elektrisch betätigbaren Zuschaltventilen 37,47, die in den vorhin erwähnten Systemdruckleitungen 13a, 13b eingefügt sind, mit den Eingangsanschlüssen der Einlassventile 6a - 6d verbindbar.
