Zur Erfassung des dem Vorderradbremskreis zugeführten Hauptbremszylinderdrucks ist zwischen dem Einlassventil und dem Hauptbremszylinder am Vorderradbremskreis ein erster Drucksensor angeordnet. Ein zweiter Drucksensor erfasst den Radbremsdruck in einer am Hinterradbremskreis angeschlossenen Hinterradbremse. Zusätzlich kann auch ein den Hauptbremszylinderdruck im Hinterradbremskreis erfassender Drucksensor in Nähe des die Hinterradbremse betätigenden Hauptbremszylinders vorgesehen sein. Die Drucksensorsignale werden u. a. zur Einstellung der gewünschten elektronischen Bremskraftverteilung zwischen Vorder- und Hinterradbremse genutzt.For detecting the master brake cylinder pressure supplied to the front wheel brake circuit, a first pressure sensor is arranged between the inlet valve and the master brake cylinder on the front wheel brake circuit. A second pressure sensor detects the wheel brake pressure in a rear brake connected to the rear wheel brake circuit. In addition, a pressure sensor detecting the master cylinder pressure in the rear wheel brake circuit may also be provided in the vicinity of the master cylinder actuating the rear wheel brake. The pressure sensor signals are u. a. used to set the desired electronic brake force distribution between front and rear brake.

Grundsätzlich gilt:
- 1. Eine Blockierneigung des Vorder- bzw. des Hinterrades wird mittels nicht abgebildeter Raddrehzahlsensoren und deren Signalauswertung im Steuergerät
8 sicher erkannt. Das im Vorderrad- bzw. imHinterradbremskreis 4 ,10 angeordnete Einlassventil6 wird über das Steuergerät8 elektromagnetisch geschlossen, um einen weiteren Druckaufbau im Vorderrad- bzw.Hinterradbremskreis 4 ,10 zu unterbinden. - 2. Sollte zur Reduzierung der Blockierneigung zusätzlich ein weiterer Druckabbau im Vorderrad- bzw.
Hinterradbremskreis 4 ,10 erforderlich sein, so wird dies durch das Öffnen des jeweilsmit dem Niederdruckspeicher 16 verbindbaren, normalerweise stromlos geschlossenen Auslassventil12 erreicht.Das Auslassventil 12 wird geschlossen, sobald die Radbeschleunigung wieder über ein bestimmtes Maß hinaus anwächst. In der Druckabbauphase bleibt das entsprechende Einlassventil6 geschlossen, so dass sich der im Vorderrad- bzw.Hinterradbremskreis 4 ,10 erzeugte Hauptbremszylinderdruck nicht auf den Vorderrad- bzw.Hinterradbremskreis 4 ,10 fortpflanzen kann. - 3. Wenn die ermittelten Schlupfwerte wieder einen Druckaufbau im Vorderrad- bzw.
Hinterradbremskreis 4 ,10 erlauben, wird das Einlassventil6 entsprechend der Anforderung des im Steuergerät8 integrierten Schlupfreglers zeitlich begrenzt geöffnet. Das für den Druckaufbau erforderliche Hydraulikvolumen wird von der Pumpe9 zu Verfügung gestellt.

That in the front wheel or in the rearwheel brake circuit 4 .10 arranged inlet valve6 is via the control unit8th Electromagnetically closed to another pressure build-up in the front andrear brake 4 .10 to prevent. - 2. Should reduce the blocking tendency additionally further pressure reduction in the front and
rear brake circuit 4 .10 Be required, this is done by opening each with thelow pressure accumulator 16 connectable normally normally closedexhaust valve 12 reached. Theoutlet valve 12 is closed as soon as the wheel acceleration increases again beyond a certain level. In the pressure reduction phase, the corresponding inlet valve remains6 closed, so that in the front orrear brake 4 .10 generated master cylinder pressure not on the front andrear brake circuit 4 .10 can reproduce. - 3. If the determined slip values again a pressure build-up in the front wheel or rear
wheel brake circuit 4 .10 allow, the inlet valve6 according to the requirement of the control unit8th integrated slip control open for a limited time. The hydraulic volume required for pressure buildup is provided by thepump 9 made available.
