Description
Die Erfindung bezieht sich auf eine Bremsanlage gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a Brake system according to the generic term of claim 1.

Es ist die Aufgabe der vorliegenden Erfindung, eine derartige Bremsanlage dahingehend zu erweitern, daß die steuerbare Druckquelle zur Betätigung einer Kupplung genutzt werden kann.It is the task of the present Invention to expand such a brake system that the controllable pressure source for actuation a clutch can be used.
Diese Aufgabe wird für eine Bremsanlage der gattungsbildenden Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is for a brake system generic type by the characterizing features of the claim 1 solved.
Weitere Ausgestaltungen der Erfindung können den Unteransprüchen entnommen werden.Further refinements of the invention can the subclaims be removed.
Die Erfindung soll im folgenden anhand eines Ausführungsbeispieles näher erläutert werden.The invention is based on the following of an embodiment are explained in more detail.
Es zeigt:It shows:

Entscheidend ist, daß ein Pedalsensor
Zusätzlich kann, was in dieser Figur nicht dargestellt ist, der Pedalsensor einen Kraftsensor enthalten, der die auf das Pedal ausgeübte Kraft mißt.Additionally, what's in this Figure is not shown, the pedal sensor contain a force sensor, the one exercised on the pedal Strength measures.

Im Verstärkermodus wird in Abhängigkeit von
den Signalen des Pedalsensors, insbesondere von den Signalen des
Wegsensors ein Druck für

Um den in der Steuereinheit
Die mit den Radbremsen
Die Radsensoren ermöglichen es, den Schlupf der Räder zu ermitteln, so daß für den Fall, daß eine oder mehrere Räder zu blockieren drohen, eine Bremsschlupfregelung stattfinden kann.The wheel sensors enable it, the slip of the wheels to determine, so that in the event that one or several wheels blockage, a brake slip control can take place.
Dazu werden Steuersignale an die
hydraulische Steuereinheit
Eine Bremsschlupfregelung läuft dabei

von der Steuerung der Antriebseinheit
Die hydraulische Steuereinheit
Die Besonderheit der Bremsanlage
liegt somit darin, daß sowohl
im Fall einer Pedalbetätigung als
auch im Falle einer Fremdbetätigung

Der von der Pumpe zur Verfügung gestellt Druck
liegt bei ca 50 bar. Dies ist ein üblicher Betätigungsdruck für Kupplungen
in Personenkraftwagen, der es ermöglicht Stellzylinder aus Kunststoff
zu verwenden. Die Antriebseinheit

Die Steuereinheit
Das beschriebene System ist insbesondere dann von Interesse, wenn im Fahrzeug auf ein Kupplungspedal verzichtet wird, und die Kupplung somit nicht vom Fahrer sondern automatisch aufgrund von Signalen einer entsprechenden Sensorik betätigt wird. Auf diese Weise kann ein halbautomatisches Getriebe realisiert werden.The system described is particularly then of interest if there is no clutch pedal in the vehicle and the clutch therefore not automatically by the driver is actuated on the basis of signals from a corresponding sensor system. In this way, a semi-automatic transmission can be realized.
Für den eingangs erwähnten Verstärkermodus hat es sich als vorteilhaft herausgestellt, mit zwei Pedalsensoren zu arbeiten, wobei der eine Sensor als Wegsensor und der andere Sensor als Kraftsensor ausgebildet ist.For the one mentioned at the beginning amp mode it turned out to be advantageous with two pedal sensors to work, one sensor as a displacement sensor and the other Sensor is designed as a force sensor.
Eine übliche Pedalcharakteristik ist nämlich dadurch gekennzeichnet, daß in einer Anfangsphase große Pedalwege zurückgelegt werden, ohne daß der Druck in den Bremskreisen überproportional ansteigt. Sobald aber ein bestimmter Druck aufgebaut worden ist, lassen sich schon mit kleinen zusätzlichen Pedalwegen überproportionale Drucksteigerungen erreichen.A common pedal characteristic is because of that characterized in that in an initial phase great Pedal travel be without the Disproportionate pressure in the brake circuits increases. But as soon as a certain pressure has been built up, can be disproportionate with small additional pedal travel Achieve pressure increases.
Die Drucksteuerung bzw -Regelung im Verstärkermodus läßt sich damit am einfachsten durchführen, indem bei kleinen Drücken die Steuerung auf die Weginformation aufbaut, während bei hohen Drücken die Kraftinformation genutzt wird.The pressure control or regulation in amplifier mode let yourself the easiest way to do that by at small pressures the control is based on the route information, while at high pressures the Power information is used.
