Hinterradbremskreis wonach das in den beiden Hauptbremszylindern
Grundsätzlich gilt für die Funktionsweise:
- 1. Eine Blockierneigung einer
der beiden Radbremsen
5 ,14 wird mittels geeigneter Raddrehzahlsensoren und deren Signalauswertung im Steuergerät sicher erkannt. Das Einlassventil17 wird – wie eingangs erwähnt – jeweils über das Steuergerät34 elektromagnetisch geschlossen, um einen weiterer Druckaufbau im hydraulisch beaufschlagten Vorderrad- und/oder Hinterradbremskreis zu unterbinden. - 2. Sollte zur Reduzierung der Blockierneigung zusätzlich ein
weiterer Druckabbau im Vorderrad- bzw. Hinterradbremskreis erforderlich
sein, so wird dies durch das Öffnen
des mit dem Niederdruckspeicher
19 verbindbaren, normalerweise stromlos geschlossenen Auslassventils18 in jedem Bremskreis erreicht. Das Auslassventil18 wird wieder geschlossen, sobald die Radbeschleunigung wieder über ein bestimmtes Maß hinaus anwächst. In der Druckabbauphase bleibt das Einlassventil17 geschlossen, so dass sich der vom Handbremshebel bzw. dem Bremspedal erzeugte Hauptzylinderdruck nicht auf den Vorderrad- bzw. Hinterradbremskreis fortpflanzen kann. - 3. Wenn die ermittelten Schlupfwerte wieder einen Druckaufbau
in dem jeweils hydraulisch betätigten
Bremskreis erlauben, wird das Einlassventil
17 entsprechend der Anforderung eines im Steuergerät integrierten Schlupfreglers zeitlich begrenzt geöffnet. Das für den Druckaufbau erforderliche Bremsflüssigkeitsvolumen wird vom Druckraum des jeweils manuell betätigten Hauptbremszylinders7 entnommen. Hierbei verändert sich je nach entnommenem Volumen der Arbeitskolbenhub, d.h. der jeweils manuell betätigte Hauptbremszylinder7 ersetzt in den Druckaufbauphasen eine Förderpumpe zur Druckversorgung für den daran angeschlossenen Bremskreis.
- 1. A blocking tendency of one of the two wheel brakes
5 .14 is reliably detected by means of suitable wheel speed sensors and their signal evaluation in the control unit. The inlet valve17 is - as mentioned above - in each case via the control unit34 Electromagnetically closed to a further pressure build-up in the hydraulically acted front and / or rear wheel to prevent the brake circuit. - 2. Should be required to reduce the blocking tendency in addition, a further pressure reduction in the front and rear brake, this is done by opening the low-pressure accumulator
19 connectable normally normally closed exhaust valve18 reached in each brake circuit. The outlet valve18 is closed again as soon as the wheel acceleration increases again beyond a certain level. In the pressure reduction phase, the inlet valve remains17 closed, so that the master cylinder pressure generated by the hand brake lever or the brake pedal can not propagate to the front wheel or rear wheel brake. - 3. If the determined slip values again allow pressure to build up in the respectively hydraulically actuated brake circuit, the inlet valve becomes
17 opened according to the requirement of a built-in slip controller in the control unit for a limited time. The brake fluid volume required for the pressure buildup is from the pressure chamber of the respective manually operated master cylinder7 taken. In this case, depending on the volume removed, the working piston stroke, ie the respectively manually actuated master cylinder, varies7 replaced in the pressure build-up phases a feed pump for pressure supply for the connected brake circuit.

Das in den Arbeitskammern vorhandene Reservevolumen ist in der Regel derart gewählt, dass ein voller Druckaufbau bzw. die für Krafträder gesetzlich vorgeschriebene Mindestverzögerung des Bremssystems gewährleistet ist.The in the working chambers existing reserve volume is usually chosen so that a full pressure build-up or the legally prescribed for motorcycles minimum delay of the brake system is.

In der weiteren Ausgestaltung des Erfindungsgedankens ist vorgesehen, dass bei einem mangelhaften Entlüftungszustand der hydraulischen Bremsanlage die Motorleistung des Kraftrades zwangsweise über ein geeignetes Motorsteuergerät automatisch reduziert wird. Zur Reduzierung der Motorleistung wird vorgeschlagen, dass ein im Motorsteuergerät des Kraftrades abgelegtes Zündkennfeld und/oder Einspritzkennfeld verändert oder auf ein hierfür geeignetes Notlaufprogramm umgeschaltet wird, sobald mittels des elektrischen Wegschalters oder durch den Wegsensor ein mangelhafter Entlüftungszustand der Bremsanlage erkannt wird.In the further embodiment of the inventive concept is provided that in case of a poor ventilation state the hydraulic brake system, the engine power of the motorcycle forcibly on a suitable engine control unit automatically is reduced. To reduce engine power, it is proposed that one in the engine control unit of the motorcycle stored ignition map and / or Injection map changed or on one for this suitable emergency program is switched as soon as using the electric Wegschalters or through the displacement sensor is a poor ventilation state the brake system is detected.
Durch die Erfindung ist somit sichergestellt, dass sowohl durch passive als auch aktive Sicherheitsvorkehrungen gute Voraussetzungen für einen hinreichenden Schutz der Verkehrsteilnehmer vorliegen.By The invention is thus ensured that both passive as well as active security precautions for a sufficient Protection of road users present.
