Abstract
Description
Die Erfindung bezieht sich auf eine Fahrzeugbremsanlage, umfassend Radbremsen, ein Bremspedal, eine Kraftübertragungseinrichtung zur Kopplung des Bremspedals mit den Radbremsen, und einen Pedalsimulator, wobei die Fahrzeugbremsanlage einen Betriebsmodus aufweist, in dem das Bremspedal von der Kraftübertragungseinrichtung entkoppelt ist und das Bremspedal mit dem Pedalsimulator zur Simulation eines definierten Kraft-Weg-Verlaufs am Bremspedal zusammenwirkt, und mindestens eine Rückfallebene, in der das Bremspedal mit der Kraftübertragungseinrichtung gekoppelt ist, um eine an dem Bremspedal anliegende Betätigungskraft mittels der Kraftübertragungseinrichtung an die Radbremsen zu übertragen.The invention relates to a vehicle brake system comprising wheel brakes, a brake pedal, a power transmission device for coupling the brake pedal with the wheel brakes, and a pedal simulator, wherein the vehicle brake system has an operating mode in which the brake pedal is decoupled from the power transmission device and the brake pedal with the pedal simulator to simulate a defined force-displacement curve on the brake pedal, and at least one fallback level in which the brake pedal is coupled to the power transmission device to transmit an applied to the brake pedal actuating force by means of the power transmission device to the wheel brakes.
Pedalsimulatoren sind als solche Stand der Technik. Sie werden überall dort benötigt, wo die Bremskraft einer Fahrzeugbremsanlage nicht mehr unmittelbar durch die vom Fahrer an einem Bremspedal aufgebrachte Betätigungskraft, sondern durch andere Energiequellen wie beispielsweise einen Elektromotor, einen Kompressor oder dergleichen erzeugt wird. Über den Pedalsimulator wird dem Fahrer beim Betätigen des Bremspedals eine haptische Rückmeldung in Form eines vorgegebenen Kraft-Weg-Verhaltens vermittelt, welche mit dem tatsächlichen Bremsverhalten der Fahrzeugbremsanlage korrespondiert, um dem Fahrer die Dosierung der Bremskraft zu erleichtern. Insbesondere kann mit dem vorgegebenen Kraft-Weg-Verhalten ein von herkömmlichen hydraulischen Fahrzeugbremsanlagen gewohntes Bremsgefühl simuliert werden. Es ist jedoch auch möglich, Kraft-Weg-Kennlinien zu realisieren, die von dem bisher gewohnten Bremsgefühl abweichen.As such, pedal simulators are state of the art. They are needed wherever the braking force of a vehicle brake system is no longer generated directly by the force applied by the driver to a brake pedal actuating force, but by other energy sources such as an electric motor, a compressor or the like. Via the pedal simulator, the driver is given a haptic feedback in the form of a predetermined force-displacement behavior when the brake pedal is actuated, which corresponds to the actual braking behavior of the vehicle brake system in order to make it easier for the driver to dose the braking force. In particular, with the given force-displacement behavior, a conventional brake application of conventional hydraulic brake systems can be simulated. However, it is also possible to realize force-displacement characteristics that deviate from the usual brake feel.
Pedalsimulatoren werden beispielsweise in Fahrzeugbremsanlagen eingesetzt, bei denen eine mechanische Kopplung zwischen dem Bremspedal und den Radbremsen in keinem Fall vorgesehen ist. Etwaigen Systemstörungen wird durch Mehrfachredundanzen vorgebeugt, so dass derartige Brake-by-wire Systeme aufwändig und teuer sind.Pedal simulators are used for example in vehicle brake systems, in which a mechanical coupling between the brake pedal and the wheel brakes is provided in any case. Any system disturbances are prevented by multiple redundancies, so that such brake-by-wire systems are complex and expensive.
Eine kostengünstigere Alternative stellen Fahrzeugbremsanlagen dar, bei denen in einem Betriebsmodus die vorgenannte mechanische Kopplung aufgehoben ist, bei einer Systemstörung jedoch automatisch zur Verfügung steht. Die vorliegende Erfindung steht im Kontext mit derartigen Fahrzeugbremsanlagen.A more cost-effective alternative is vehicle braking systems, in which the aforementioned mechanical coupling is canceled in an operating mode, but is automatically available in the event of a system fault. The present invention is in the context of such vehicle brake systems.
Um Interaktionen zwischen dem Betriebsmodus und der mechanischen Rückfallebene zu vermeiden, ist eine derartige Bremsanlage in der Regel derart ausgeführt, dass zwischen einem mit dem Bremspedal gekoppelten Betätigungselement und der Kraftübertragungseinrichtung ein Spiel besteht, das im normalen Betriebsmodus aufrechterhalten und zur Pedalsimulation genutzt wird, im Störungsfall jedoch durch den Fahrer überwunden werden kann. Entsprechende Fahrzeugbremsanlagen der eingangs genannten Art sind aus der
Davon ausgehend liegt der Erfindung die Aufgabe zu Grunde, eine Fahrzeugbremsanlage der eingangs genannten Art zu schaffen, welche einen einfachen Aufbau und eine hohe Funktionssicherheit aufweist.Based on this, the object of the invention to provide a vehicle brake system of the type mentioned, which has a simple structure and high reliability.
Diese Aufgabe wird durch eine Fahrzeugbremsanlage gemäß Patentanspruch 1 gelöst. Die erfindungsgemäße Fahrzeugbremsanlage zeichnet sich insbesondere dadurch aus, dass eine Abstützeinrichtung mit einer Kammer vorgesehen ist, deren Volumen durch eine Schaltventileinrichtung öffenbar und absperrbar ist, und dass der Pedalsimulator an der Abstützeinrichtung abgestützt ist, wobei die Schaltventileinrichtung im Betriebsmodus die Kammer absperrt, in der mindestens einen Rückfallebene hingegen öffnet.This object is achieved by a vehicle brake system according to claim 1. The vehicle brake system according to the invention is particularly characterized in that a support device is provided with a chamber whose volume can be opened and shut off by a switching valve device, and that the pedal simulator is supported on the support device, wherein the switching valve device shuts off the chamber in the operating mode, in the at least a fallback, however, opens.
Durch die erfindungsgemäße Konfiguration wird die in der
Durch eine Entlastung der Abstützeinrichtung lässt sich das Spiel schnell und wirkungsvoll abbauen, um einen mechanischen Durchgriff, d. h. eine Übertragung der Pedalkraft des Fahrers an die Radbremsen zu ermöglichen.By relieving the support device, the game can be quickly and effectively reduced to a mechanical penetration, d. H. to allow a transmission of the pedal force of the driver to the wheel brakes.
Die Abstützeinrichtung lässt sich konstruktiv einfach bewerkstelligen und günstig am Fahrzeugaufbau unterbringen.The support means can be structurally easy to accomplish and accommodate cheap on the vehicle body.
Vorzugsweise arbeitet die Abstützeinrichtung hydraulisch. Eine pneumatische Variante ist jedoch ebenfalls möglich, wobei dann allerdings die Kompressibilität des Arbeitsmediums mit berücksichtigt werden muss.Preferably, the support device operates hydraulically. However, a pneumatic variant is also possible, in which case, however, the compressibility of the working medium must be taken into account.
In einer vorteilhaften Ausgestaltung ist die Schaltventileinrichtung stromlos offen, so dass bei einer Störung der Fahrzeugelektrik die mechanische Rückfallebene automatisch zur Verfügung steht. Es ist jedoch auch möglich, beispielsweise bei einem erkannten Fehler in der Erfassung der Betätigung des Bremspedals die Schaltventileinrichtung gezielt zu öffnen.In an advantageous embodiment, the switching valve device is normally open, so that in the event of a fault in the vehicle electrics, the mechanical fallback level is automatically available. It However, it is also possible to selectively open the switching valve device, for example, in a detected error in the detection of the operation of the brake pedal.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen angegeben.Further advantageous embodiments of the invention are specified in the patent claims.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in:The invention will be explained in more detail with reference to an embodiment shown in the drawing. The drawing shows in:

Fahrzeugbremsanlagen der vorstehend erläuterten Art eignen sich insbesondere für Fahrzeuge, die mit einem Elektroantrieb ausgestattet sind, sei es als Hybridfahrzeug mit einer Kombination aus Elektro- und Verbrennungsmotor oder als reines Elektrofahrzeug. Bei einer Bremsung wird über den Elektroantrieb versucht, kinetische Energie in elektrische Energie zu verwandeln, um diese z. B. für einen späteren Beschleunigungsvorgang zu nutzen. Zur optimalen Rekuperation wird daher bei einer Bremsung zunächst der Elektroantrieb genutzt, während möglichst wenig mit den Radbremsen verzögert wird. Da Elektroantriebe nicht beliebige Leistungen rekuperieren können, wird in Abhängigkeit der Fahrgeschwindigkeit ein Überblenden zwischen elektrischer Abbremsung und Reibungsbremsung über die Radbremsen vorgenommen. Mit der vorstehend erläuterten Konfiguration wird vermieden, dass solche Überblendvorgänge am Bremspedal spürbar sind.Vehicle brake systems of the type described above are particularly suitable for vehicles that are equipped with an electric drive, be it as a hybrid vehicle with a combination of electric and combustion engine or as a pure electric vehicle. During braking, the electric drive is trying to transform kinetic energy into electrical energy to this z. B. for a later acceleration process to use. For optimal recuperation, the electric drive is therefore initially used during braking, while as little as possible is delayed with the wheel brakes. Since electric drives can not recuperate any services, a cross-fading between electrical braking and friction braking on the wheel brakes is made depending on the driving speed. With the above-described configuration, it is avoided that such cross-fading operations on the brake pedal are noticeable.
Die Erfindung wurde vorstehend anhand eines Ausführungsbeispiels näher erläutert. Sie ist jedoch nicht hierauf beschränkt, sondern umfasst alle durch die Patentansprüche definierten Ausgestaltungen.The invention has been explained above with reference to an embodiment. However, it is not limited thereto, but includes all the embodiments defined by the claims.
