Description
Die Erfindung betrifft eine Bremsanlage für Kraftfahrzeuge gemäß dem Oberbegriff von Anspruch 1.The invention relates to a brake system for motor vehicles according to the preamble of claim 1.
Aus der
Es ist daher Aufgabe der vorliegenden Erfindung, eine einfachere und damit kostengünstigere „Brake-by-wire“-Bremsanlage bereitzustellen, welche jedoch den gleichen Funktionsumfang bietet.It is therefore an object of the present invention to provide a simpler and thus more cost-effective "brake-by-wire" -Bremsanlage, but which offers the same range of functions.
Diese Aufgabe wird erfindungsgemäß durch eine Bremsanlage gemäß Anspruch 1 gelöst.This object is achieved by a brake system according to claim 1.
Der Erfindung liegt der Gedanke zugrunde, dass der Hauptbremszylinder einkreisig ausgeführt ist, wobei der Druckraum des Hauptbremszylinders über ein Trennventil mit einer Bremskreisversorgungsleitung trennbar verbunden ist, an welche alle Radbremsen angeschlossen sind und welche über ein Zuschaltventil mit der Druckbereitstellungseinrichtung trennbar verbunden ist. Somit sind nur zwei Ventile zum Trennen der Radbremsen von dem Hauptbremszylinder und der Druckbereitstellungseinrichtung zur Realisierung der „Brake-by-wire“-Betriebsart bzw. der Rückfallbetriebsart notwendig.The invention is based on the idea that the master cylinder is designed in a single-circuit, wherein the pressure chamber of the master cylinder is separably connected via a release valve to a brake circuit supply line, to which all wheel brakes are connected and which is separably connected via a Zuschaltventil with the pressure supply device. Thus, only two valves for separating the wheel brakes of the master cylinder and the pressure supply device for the realization of the "brake-by-wire" mode or the fallback mode are necessary.
Die Erfindung bietet den Vorteil, dass der einkreisige Hauptbremszylinder einfacher und kostengünstiger ist. Weiterhin ist es vorteilhaft, dass der Hauptbremszylinder kürzer als ein Tandemhauptbremszylinder ist, da so die Baulänge des Bremsaggregats in Fahrzeuglängsrichtung verringert werden kann. The invention offers the advantage that the single-circuit master cylinder is simpler and less expensive. Furthermore, it is advantageous that the master cylinder is shorter than a tandem master cylinder, since so the length of the brake assembly can be reduced in the vehicle longitudinal direction.
Bei einer im Vergleich zu einem Tandemhauptbremszylinder kürzeren Baulänge des Hauptbremszylinders der erfindungsgemäßen Bremsanlage kann vorteilafterweise die Rückstellfeder des Hauptbremszylinders, welche den Kolben des Hauptbremszylinders in einer Ausgangslage positioniert, länger als bei einem Tandemhauptbremszylinder ausgeführt sein. Hierdurch kann eine geringere Federsteifigkeit der Rückstellfeder gewählt werden, welche vorteilhaft ist, da so die Kraft-Weg-Charakteristik des Bremspedals der „Brake-by-wire“-Bremsanlage kostengünstig an die eines konventionellen Bremssystems mit Vakuumbremskraftverstärker angenähert werden kann.In a shorter compared to a tandem master cylinder length of the master cylinder of the brake system according to the invention may advantageously be performed longer than in a tandem master cylinder, the return spring of the master cylinder, which positions the piston of the master cylinder in a starting position. In this way, a lower spring stiffness of the return spring can be selected, which is advantageous because the force-travel characteristics of the brake pedal of the "brake-by-wire" -Bremsanlage can be approximated cost of a conventional brake system with vacuum brake booster.
In Bremsanlagen mit einer Entkopplung des Fahrzeugführers von den Radbremsen kann ein elektrischer Ausfall der Bremsanlage gerade dann stattfinden, wenn der Fahrzeugführer das Bremspedal stark betätigt hat, der Druck an allen Rädern aber sehr niedrig ist, weil z.B. eine Antiblockierregelung oder eine regenerative Bremsung stattfindet. In dieser Situation hat die erfindungsgemäße Bremsanlage den Vorteil, dass der Fahrzeugführer nach dem elektrischen Ausfall an allen vier Rädern Bremskraft aufbauen kann.In brake systems with a decoupling of the driver from the wheel brakes, an electrical failure of the brake system can take place just when the driver has pressed the brake pedal strongly, but the pressure on all wheels is very low, because e.g. an anti-skid control or regenerative braking takes place. In this situation, the brake system according to the invention has the advantage that the driver after the electrical failure on all four wheels can build up braking power.
Bevorzugt ist die Simulationseinrichtung mittels eines Simulatorfreigabeventils zu- und abschaltbar ausgeführt. Das Simulatorfreigabeventil ist besonders bevorzugt in der hydraulischen Verbindung zwischen der Simulationseinrichtung und dem Hauptbremszylinder angeordnet.The simulation device is preferably designed to be switched on and off by means of a simulator release valve. The simulator release valve is particularly preferably arranged in the hydraulic connection between the simulation device and the master brake cylinder.
Zur Überwachung der Bremsanlage, z.B. auf Leckagen, ist es bevorzugt, dass der Druckraum des Hauptbremszylinders über ein Diagnoseventil mit einem dem Hauptbremszylinder zugeordneten, unter Atmosphärendruck stehenden Druckmittelvorratsbehälter trennbar verbunden ist. Damit ein Abfließen von Druckmittel im Falle einer Bremspedalbetätigung durch den Fahrzeugführer sicher verhindert wird, wird die hydraulische Verbindung zwischen Druckraum und Diagnoseventil besonders bevorzugt durch eine Betätigung des Bremspedals getrennt.For monitoring the brake system, e.g. On leaks, it is preferred that the pressure chamber of the master cylinder is connected via a diagnostic valve with a master cylinder associated with the cylinder, under atmospheric pressure pressure medium reservoir is separably connected. So that a drainage of pressure medium in the event of a brake pedal actuation by the driver is reliably prevented, the hydraulic connection between the pressure chamber and the diagnostic valve is particularly preferably separated by an actuation of the brake pedal.
Bevorzugt umfasst die Bremsanlage pro Radbremse ein Einlassventil sowie ein Auslassventil zum Einstellen radindividueller Bremsdrücke, die aus dem Bremskreisversorgungsdruck in der Bremskreisversorgungsleitung abgeleitet werden, wobei im nicht angesteuerten Zustand die Einlassventile den Bremskreisversorgungsdruck zu den Radbremsen weiterleiten und die Auslassventile ein Abströmen von Druckmittel aus den Radbremsen sperren.The brake system per wheel brake preferably comprises an inlet valve and an outlet valve for adjusting wheel-specific brake pressures which are derived from the brake circuit supply pressure in the brake circuit supply line, wherein in the non-actuated state, the intake valves forward the brake circuit supply pressure to the wheel brakes and the exhaust valves block outflow of pressure medium from the wheel brakes ,
Besonders bevorzugt sind alle Auslassventile über eine gemeinsame hydraulische Verbindung mit einem dem Hauptbremszylinder zugeordneten, unter Atmosphärendruck stehenden Druckmittelvorratsbehälter verbunden.With particular preference, all the outlet valves are connected via a common hydraulic connection to a pressure medium reservoir associated with the master brake cylinder and under atmospheric pressure.
Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Bremsanlage umfasst die Bremsanlage genau zwölf elektrisch betätigbare Ventile, nämlich das zwischen dem Druckraum und der Bremskreisversorgungsleitung angeordnete Trennventil, das zwischen der Druckbereitstellungseinrichtung und der Bremskreisversorgungsleitung angeordnete Zuschaltventil, ein Simulatorfreigabeventil zum Zu– und Abschalten der Simulationseinrichtung, ein zwischen dem Druckraum und einem Druckmittelvorratsbehälter angeordnetes Diagnoseventil sowie ein Einlassventil und ein Auslassventil je einer der vier Radbremsen zum Einstellen radindividueller Bremsdrücke. Durch die Reduzierung der Anzahl der Ventile auf zwölf wird es möglich, einen bereits bekannten Ventiltreiber-Mikrochip (IC: integrierter Schaltkreis oder integrated circuit) einer konventionellen Bremsanlage mit Vakuum-Bremskraftverstärker und Fahrdynamikregelung, welche im Ganzen zwölf Ventile umfasst, für die „Brake-by-wire“-Bremsanlage zu verwenden. So fallen keine zusätzlichen Kosten für die Entwicklung eines neuen Ventiltreiber- Mikrochips zur Ansteuerung von mehr als zwölf Ventilen oder für die Verwendung von mehr als einem Ventiltreiber- Mikrochip an.According to a preferred embodiment of the brake system according to the invention, the brake system comprises exactly twelve electrically actuated Valves, namely the separating valve arranged between the pressure chamber and the brake circuit supply line, the connection valve arranged between the pressure supply device and the brake circuit supply line, a simulator release valve for connecting and disconnecting the simulation device, a diagnosis valve arranged between the pressure chamber and a pressure medium reservoir, and an inlet valve and an outlet valve one each the four wheel brakes for adjusting wheel-specific brake pressures. By reducing the number of valves to twelve, it becomes possible to use an already known valve driver microchip (integrated circuit or integrated circuit) of a conventional brake system with vacuum brake booster and vehicle dynamics control, which comprises a total of twelve valves, for the "brake" by-wire "brake system to use. There is no additional cost to develop a new valve driver microchip to drive more than 12 valves or to use more than one valve driver microchip.
Bevorzugt wird die Druckbereitstellungseinrichtung durch eine Zylinder-Kolben-Anordnung mit nur einem hydraulischen Druckraum gebildet, deren Kolben durch einen elektromechanischen Aktuator betätigbar ist. So ist eine präzise und schnelle Druckstellung möglich.Preferably, the pressure-providing device is formed by a cylinder-piston arrangement with only one hydraulic pressure chamber whose piston can be actuated by an electromechanical actuator. So a precise and fast print position is possible.
Bevorzugt umfasst die Bremsanlage an den Rädern mindestens einer Achse auch ein regeneratives Bremssystem.The brake system preferably also comprises a regenerative braking system on the wheels of at least one axle.
Gemäß einer anderen bevorzugten Ausführungsform der erfindungsgemäßen Bremsanlage umfasst diese pro Radbremse lediglich ein Einlassventil zum Einstellen radindividueller Bremsdrücke, die aus dem Bremskreisversorgungsdruck in der Bremskreisversorgungsleitung abgeleitet werden. Die Bremsanlage wird dann im sogenannten Multiplex-Verfahren betrieben. Diese Ausführungsform bietet den Vorteil, dass weniger elektrisch ansteuerbare Ventile notwendig sind. Besonders bevorzugt umfasst die Bremsanlage genau die folgenden acht elektrisch betätigbaren Ventile: das zwischen dem Druckraum und der Bremskreisversorgungsleitung angeordnete Trennventil, das zwischen der Druckbereitstellungseinrichtung und der Bremskreisversorgungsleitung angeordnete Zuschaltventil, ein Simulatorfreigabeventil zum Zu- und Abschalten der Simulationseinrichtung, ein zwischen dem Druckraum und einem Druckmittelvorratsbehälter angeordnetes Diagnoseventil sowie ein Einlassventil je einer von vier Radbremsen zum Einstellen radindividueller Bremsdrücke.According to another preferred embodiment of the brake system according to the invention, this per wheel brake comprises only one inlet valve for setting wheel-specific brake pressures, which are derived from the brake circuit supply pressure in the brake circuit supply line. The brake system is then operated in the so-called multiplex process. This embodiment offers the advantage that less electrically controllable valves are necessary. Particularly preferably, the brake system comprises exactly the following eight electrically actuatable valves: the separating valve arranged between the pressure chamber and the brake circuit supply line, the connection valve arranged between the pressure supply device and the brake circuit supply line, a simulator release valve for connecting and disconnecting the simulation device, between the pressure chamber and a pressure medium reservoir arranged diagnostic valve and an intake valve each one of four wheel brakes for adjusting wheel-specific brake pressures.
Um den Vorteil einer geringeren Anzahl von Ventilen bei jedoch nicht zu großen Mehrkosten aufgrund von multiplexfähigen Einlassventilen zu erzielen, umfasst die Bremsanlage nach einer weiteren bevorzugten Ausführungsform pro Radbremse der ersten Fahrzeugachse ein Einlassventil sowie ein Auslassventil zum Einstellen radindividueller Bremsdrücke und pro Radbremse der zweiten Fahrzeugachse lediglich ein Einlassventil zum Einstellen radindividueller Bremsdrücke, die aus dem Bremskreisversorgungsdruck in der Bremskreisversorgungsleitung abgeleitet werden.In order to achieve the advantage of a smaller number of valves but not too large additional costs due to multiplexable intake valves, the brake system according to a further preferred embodiment per wheel brake of the first vehicle axle, an intake valve and an exhaust valve for adjusting wheel-individual brake pressures and per wheel brake of the second vehicle axle only an intake valve for adjusting wheel-specific brake pressures derived from the brake circuit supply pressure in the brake circuit supply line.
