Description
Die Erfindung betrifft eine elektronisch geregelte Fahrzeugbremsanlage mit Traktionskontrolle oder Fahrstabilitätsprogramm (ESP) wobei fahrerunabhängig an einer oder an mehreren Radbremsen ein Bremsdruck aufgebaut wird, um die Fahrstabilität oder die Traktion zu verbessern.The The invention relates to an electronically controlled vehicle brake system with traction control or driving stability program (ESP) being independent of the driver one or more wheel brakes a brake pressure is built up, about driving stability or to improve the traction.
In elektronisch geregelten Bremssystemen (EBS), wie insbesondere bei dem in Bild 1 dargestellten ESP-System, gibt es prinzipiell zwei Möglichkeiten, Bremsdruck aufzubauen. Bei Normalbremsungen wird der Bremsdruck von der Bremsenbetätigungseinheit bereitgestellt. Bei elektronisch gesteuerten, fahrerunabhängigen, Bremsungen kann – sofern die Bremsenbetätigungseinheit elektrisch steuerbar ist – ein Teil des benötigten Bremsdrucks von dieser bereitgestellt werden. Im wesentlichen und insbesondere wenn hohe Drücke benötigt werden wird der dieser Bremsdruck jedoch von der, in der EBS-Hydraulikeinheit enthaltenen Pumpe erzeugt. Dabei ist jedem von wenigstens zwei Bremskreisen wenigstens eine eigenständige Pumpe zugeordnet. Bei elektronisch gesteuerten Regelungsaktionen wie einem ESP- oder einem ARP-Eingriff (ARP=Anti-Rollover=Überschlagverhinderung) muss oft nur in einem Bremskreis und dabei oft auch nur in einer Radbremse Druck aufgebaut werden, um das Fahrzeug mit einem schnellen und gezielten radindividuellen Bremseingriff zu stabilisieren. Nach dem Stand der Technik ist es bekannt, für den Druckaufbau die Pumpe des betroffenen Bremskreises einzusetzen.In electronically controlled braking systems (EBS), in particular at In principle, the ESP system shown in Figure 1 has two Options, Build up brake pressure. In normal braking, the brake pressure from the brake operating unit provided. For electronically controlled, driver-independent, Braking can - provided the brake operating unit is electrically controllable - a Part of the needed Brake pressure be provided by this. Essentially and in particular when high pressures needed However, this brake pressure will be from the, in the EBS hydraulic unit generated pump generated. Each of at least two brake circuits is at least an independent one Pump assigned. For electronically controlled control actions such as ESP or ARP (ARP = anti-rollover) often only in a brake circuit and often only in a wheel brake Pressure to be built up to the vehicle with a fast and to stabilize targeted wheel-specific braking intervention. To In the prior art, it is known for the pressure buildup of the pump of the affected brake circuit.
Der Erfindung liegt die Aufgabe zu Grunde, eine Fahrzeugsbremsanlage mit einem Fahrstabilitätsprogramm zu verbessern. Die Dynamik des Systems soll im Interesse von Funktionen wie ARP, ADC (Automatic Distance Control = Abstandsregelung) oder zur Unfallverhinderung verbessert werden.Of the Invention is based on the object, a vehicle brake system with a driving stability program to improve. The dynamics of the system should be in the interest of functions like ARP, ADC (Automatic Distance Control) or to improve accident prevention.
Die Aufgabe wird erfindungsgemäß gelöst, indem für den Druckaufbau an einer Radbremse oder in einem Bremskreis die Pumpen von wenigstens zwei Bremskreisen eingesetzt werden.The The object is achieved according to the invention by for the Pressure buildup on a wheel brake or in a brake circuit the pumps be used by at least two brake circuits.
Die
In einer hydraulischen Verbindung zwischen dem Hauptbremszylinder und der Saugseite der Pumpe befindet sich ein, in der Grundstellung geschlossenes Umschaltventil, das in einen Leitungsabzweig eingesetzt ist, der jeweils zwischen Trennventil und dem Hauptbremszylinder an die zu den Radbremsen HR, VR, HL, VL führende hydraulische Verbindung angeschlossen ist. Zum Druckaufbau mit Hilfe der Pumpe wird der Hauptzylinder, durch Aktivieren des Trennventils, von der Druckseite der Pumpe abgetrennt. Gleichzeitig wird das Umschaltventil geöffnet, wodurch die Saugseite der Pumpe aus dem Hauptbremszylinder mit Druckmittel versorgt wird. So wird unabhängig vom Druckniveau des Hauptbremszylinders ein für fahrzeugstabilisierende Bremseingriffe vorgesehener Druck bereitgestellt, der mit Hilfe der dem betreffenden Fahrzeugrad zugeordneten Ein- und Auslassventile radindividuell dosiert werden kann.In a hydraulic connection between the master cylinder and the suction side of the pump is in, in the basic position closed diverter valve, which is inserted in a line branch is, between each isolation valve and the master cylinder to the hydraulic connection leading to the wheel brakes HR, VR, HL, VL connected. To build up pressure with the help of the pump is the Master cylinder, by activating the isolation valve, from the pressure side the pump is disconnected. At the same time the switching valve is opened, whereby the suction side of the pump from the master cylinder with pressure medium is supplied. This is how it becomes independent from the pressure level of the master cylinder for a vehicle-stabilizing brake interventions intended pressure provided by means of the relevant Vehicle wheel associated intake and exhaust valves individually can be dosed.
In der hydraulischen Verbindung zwischen Hauptbremszylinder und Radbremsen oder alternativ direkt am Hauptbremszylinder befindet sich ferner ein Drucksensor, der den Druck im Hauptbremszylinder erfaßt. Radbremsseitig können jeweils Drucksensoren vorgesehen werden, so dass eine radindividuelle Bremsdruckerfassung ermöglicht ist. Mit anderen Worten kann sowohl der von einem Fahrzeugführer eingesteuerte Vordruck, als auch der individuelle, radbremsseitig vorliegende Druck messtechnisch erfasst werden.In the hydraulic connection between master cylinder and wheel brakes or alternatively directly to the master cylinder is also a Pressure sensor that detects the pressure in the master cylinder. wheel brake can each pressure sensors are provided, so that a wheel-individual Brake pressure detection enabled is. In other words, both of the driver-controlled Form, as well as the individual, radbremsseitig present Pressure metrologically be detected.
Um im fremdbetätigten Modus die Pulsationen der Pumpe zu dämpfen, befindet sich auf jeder Druckseite der Pumpe jeweils eine Dämpfungskammer, welche druckseitige Pulsationen reduziert.Around in the externally operated Mode to dampen the pulsations of the pump is located on each pressure side the pump each have a damping chamber, which reduces pressure-side pulsations.
Radeinlass- und Radauslassventile erfordern keine nähere Erläuterung und ermöglichen eine radindividuelle Schlupfregelung, indem beispielsweise aus den Radbremsen HR, HL, VR, VL abgelassenes Überschuß-Druckmittelvolumen über den Druckmittelspeicher, über die jeweilige Pumpe und über die Dämpfungskammer in den Hauptbremszylinder zurück gefördert wird.Radeinlass- and Radauslassventile require no further explanation and allow a wheel-specific slip control, for example, from the wheel brakes HR, HL, VR, VL excess excess pressure fluid volume through the accumulator, via the respective pump and the damping chamber in the master cylinder to is promoted.

Der gebündelte Druckmittelvolumenstrom wird gezielt der gewünschten Radbremse zugeführt. Bei den bekannten Bremsanlagen basiert die eingesteuerte Druckerhöhung ausschließlich auf dem Fördervermögen der Pumpe desjenigen Bremskreises, in dem der Regelvorgang durchgeführt werden soll. Die Pumpe des anderen Bremskreises läuft leer. Erfindungsgemäß sind – entsprechenden Volumen- oder Druckbedarf vorausgesetzt – dagegen die Pumpenmittel aller Bremskreise eingebunden, um an einem der Räder einen Regeleingriff vorzunehmen. Damit eignet sich die Erfindung insbesondere für Bremsanlagen, deren Komponenten und Radbremsen eine hohe Volumenaufnahme aufweisen. Dies ist beispielsweise der Fall, wenn die Radbremsen ein hohes Lüftspiel aufweisen, oder wenn Elastizitäten einen Teil der aufgebrachten hydraulischen Stellenergie aufzehren. Dies kann besonders der Fall sein, wenn Radbremsbeläge weitgehend verschlissen sind, oder wenn große, schwere Kraftfahrzeuge (light trucks) mit entsprechend großen Bremskräften vorliegen.Of the bundled Pressure fluid flow is selectively fed to the desired wheel brake. at the known brake systems based on the controlled pressure increase exclusively the eligibility of the Pump of that brake circuit in which the control process is carried out should. The pump of the other brake circuit runs empty. According to the invention are - corresponding Required volume or pressure - on the other hand, the pumping means all brake circuits involved in order to make a control intervention on one of the wheels. In order to the invention is particularly suitable for brake systems whose components and wheel brakes have a high volume absorption. This is for example the case when the wheel brakes have a high clearance, or if Elasticities one Consume part of the applied hydraulic pressure energy. This may be particularly the case when wheel brake pads are largely worn out, or if big, heavy vehicles (light trucks) are present with correspondingly large braking forces.
In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass die Trennkolbeneinheiten elektronisch gesteuert sperrbar ausgebildet ist, und dass die Sperrung vorzugsweise hydraulisch mittels Elektromagnetventilen erfolgt. Bei der in Bild 4 dargestellten Bremsanlage wird für jede Förderleistungsübertragungsrichtung eine separate Kombination aus einer Trennkolbeneinheit und einem Trennventil eingesetzt. Die stromlos geschlossenen Trennventile sind so angeordnet, dass sie eine Förderleistungseinleitung aus dem abgebenden Bremskreis in die Trennkolbeneinheit verhindern können, falls ein Übertrag in dieser Richtung nicht gewünscht ist. Für eine Förderleistungsübertragung in die andere Richtung kann unabhängig davon das andere Trennventil geöffnet werden. Fall nur die Pulsationsdämpfungsfunktion gefragt ist, beispielsweise im normalen ABS-Rückförderbetrieb, sind beide Trennventile geschlossen. Mit diesen Maßnahmen wird eine umfassende Steuerbarkeit der Förderleistungen der Pumpen ermöglicht. Beispielsweise kann mit einer solchen Schaltung vermieden werden, dass eine besonders dynamische Beaufschlagung der Radbremse einer Vorderachse auch zu einer addierten Druckaufbauwirkung bei einem Hinterrad führt. Denn Hinterräder sind für den Erhalt der Seitenführungskraft unerlässlich, so dass an dieser Stelle meist ein feinfühligerer Druckaufbau mit der Förderleistung nur einer Pumpe bevorzugt wird. Sollte dennoch – beispielsweise für einen ESP-Eingriff – ein Druckaufbau mit doppelter Förderleistung gewünscht sein, so ist dies ebenfalls möglich. Damit ermöglicht die Erfindung eine feinfühlige, graduelle Anpassung von Regeleingriffen zwecks Anpassung an den jeweiligen Anwendungsfall.In Another embodiment of the invention is proposed that the Separating piston units formed electronically controlled lockable is, and that the blockage preferably hydraulically by means of solenoid valves he follows. For the brake system shown in Figure 4 is for each conveying power transmission direction a separate combination of a separating piston unit and a Separating valve used. The normally closed isolation valves are arranged so that they have a flow introduction prevent the donating brake circuit in the separating piston unit, if a carry not desired in this direction is. For a delivery power transfer in the other direction, regardless of the other isolation valve be opened. Case only the pulsation damping function is required is, for example, in the normal ABS recirculation mode, are both isolation valves closed. With these measures a comprehensive controllability of pump capacities is made possible. For example can be avoided with such a circuit that a particular dynamic loading of the wheel brake of a front axle too an added pressure build-up effect on a rear wheel leads. Because rear wheels are for maintaining the cornering power essential so that at this point usually a more sensitive pressure build-up with the output only one pump is preferred. Should nevertheless - for example for an ESP intervention - a pressure build-up with double capacity required this is also possible. This allows the invention a sensitive, gradual Adaptation of control interventions to adapt to the respective Application.
Die Funktion von Dämpfungskammern kann in allen aufgeführten Fällen von den hydraulischen Druckkammern der Trennkolbeneinheiten wahrgenommen werden. Die im Stand der Technik bekannten Dämpfungskammern können daher prinzipiell entfallen.The Function of damping chambers can be listed in all make perceived by the hydraulic pressure chambers of the separating piston units become. The known in the art damping chambers can therefore eliminated in principle.
Die Komponenten und Funktionen des erfindungsgemäßen Aggregates haben keinen störenden Einfluss auf die üblichen Funktionen einer elektronisch geregelten Bremsanlage. Die Erfindung ist insbesondere für die Verwendung im Zusammenhang mit Schaltventilen beziehungsweise analogisierten Schaltventilen wie auch in Verbindung mit Analogventilen sowie in Verbindung mit Sensoren für THZ- und Radbremsdrücke verwendbar.The components and functions of the unit according to the invention have no disturbing influence on the usual functions of an electronically controlled brake system. The invention is particularly suitable for use in connection with switching valves or analogized switching valves as well as in conjunction with analog valves and in conjunction with sensors for THZ sensors. and wheel brake pressures usable.
Vorteile der ErfindungAdvantages of invention
Für einen fahrerunabhängigen Druckaufbau in nur einer Radbremse werden alle in der Hydraulikeinheit vorhandenen Pumpen – insbesondere auch diejenige(n) eines nicht betroffenen Bremskreises – eingesetzt. Die Erfindung eignet sich ganz besonders für Bremsanlagen, welche mehr als zwei Fördervorrichtungen aufweisen, um die Aktivität dieser Fördervorrichtungen an den jeweiligen Anwendungsfall anzupassen. Die Medientrennung der beiden hydraulischen Bremskreise bleibt erhalten.For one driver-independent Pressure build-up in just one wheel brake will all be in the hydraulic unit existing pumps - in particular also that (s) of an unaffected brake circuit - used. The invention is particularly suitable for brake systems, which more as two conveyors exhibit the activity these conveyors to adapt to the particular application. The media separation the two hydraulic brake circuits is maintained.
Wesentlich ist eine Bremsenhydraulik mit zusammenschaltbaren Pumpenkreisen, wobei mit Hilfe von Trennkolben die Medientrennung der beiden Bremskreise erreicht wird. Unmittelbar nach einem Druckaufbau mit zusammengeschalteten Kreisen kann – auch wenn der Regelungsvorgang noch andauert – durch geeignetes Ansteuern von Ventilen kann der Anfangszustand der Trennkolbenpositionen und damit eine ausgeglichene Volumenbilanz beider Kreise hergestellt werden.Essential is a brake hydraulics with interconnectable pump circuits, wherein with the help of separating piston, the media separation of the two brake circuits is reached. Immediately after a pressure build-up with interconnected Circling can - too if the regulation process still lasts - by suitable driving of valves, the initial state of the separating piston positions and thus produced a balanced volume balance of both circles become.
