Description
Die Erfindung betrifft ein Verfahren zu einer Feststellbetätigung einer hydraulischen Fahrzeugbremsanlage mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a method for a locking operation a hydraulic vehicle brake system having the features of the preamble of Claim 1.
Stand der TechnikState of the art
Die
Offenlegungsschrift
Der Bremskraftverstärker der bekannten Fahrzeugbremsanlage ist ein elektromechanischer Bremskraftverstärker mit einem Elektromotor und einem Spindeltrieb zur Wandlung einer rotatorischen Antriebsbewegung des Elektromotors in eine translatorische Abtriebsbewegung zur Beaufschlagung des Hauptbremszylinders. Der bekannte Bremskraftverstärker ist steuerbar, womit gemeint ist, dass seine auf den Hauptbremszylinder ausübbare Verstärkerkraft unabhängig von einer Muskelkraftbetätigung des Hauptbremszylinders steuerbar ist. Das schließt eine Muskelkraftsteuerung des Hauptbremszylinders nicht aus.Of the Brake booster of the known vehicle brake system is an electromechanical brake booster with a Electric motor and a spindle drive for the conversion of a rotary drive movement of the electric motor in a translational output movement for acting of the master cylinder. The well-known brake booster is controllable, which means that its on the master cylinder exercisable amplifier power independently from a muscle power operation of the master cylinder is controllable. That includes a muscle strength control of the Master cylinder is not off.

Offenlegungsschrift
Offenbarung der ErfindungDisclosure of the invention
Mindestens eine Radbremse der Fahrzeugbremsanlage gemäß der Erfindung weist eine Feststelleinrichtung auf, mit der die Radbremse in betätigtem Zustand feststellbar ist. Das erfindungsgemäße Verfahren mit den Merkmalen des Anspruchs 1 sieht zu einer Feststellbetätigung vor, die Radbremse durch Betätigung des Hauptbremszylinders mit dem Bremskraftverstärker hydraulisch zu betätigen und in betätigtem Zustand festzustellen, so dass die Radbremse auch ohne hydraulischen Druck betätigt bleibt. Ein Vorteil der Erfindung ist, dass die Feststellbremsbetätigung mit dem Bremskraftverstärker erfolgt, dessen Lebensdauer für eine sehr große Betätigungszahl ausgelegt ist und der normalerweise während eines Kraftfahrzeugslebens weder getauscht noch repariert werden muss. Rückförderpumpen, also Hydropumpen von Fahrzeugbremsanlagen mit einer Schlupfregelung sind dafür nicht ausgelegt. Bei einem regelmäßigen Bremsdruckaufbau mit einer solchen Hydropumpe zur Feststellbetätigung einer Fahrzeugbremsanlage muss mit einem frühzeitigen Verschleiß und Defekt der Hydro-/Rückförderpumpe gerechnet werden. Ein weiterer Vorteil der Erfindung ist die vergleichsweise leise Betätigung der Fahrzeugbremsanlage mit dem Bremskraftverstärker, dessen Geräuschentwicklung in einem Fahrgastraum eines Kraftwagens nicht oder nur leise wahrnehmbar ist. Auch sind Druckpulsationen oder dgl., wie sie von Kolbenpumpen als Rückförderpumpen bekannt sind und die einen Fahrzeugführer irritieren können, einem Bremskraftverstärker fremd.At least a wheel brake of the vehicle brake system according to The invention has a locking device with which the wheel brake can be determined in the actuated state. The inventive method with the features of claim 1 provides for a locking operation before, the wheel brake by operating the master cylinder Hydraulic operation with the brake booster and to determine in the activated state, so that the wheel brake also remains actuated without hydraulic pressure. An advantage the invention is that the parking brake with the brake booster, whose life for a very large number of actuators is designed and that usually during a motor vehicle life must not be exchanged or repaired. Recirculating pumps, So hydraulic pumps of vehicle brake systems with a slip control are not designed for that. At a regular Brake pressure build-up with such a hydraulic pump for locking operation A vehicle brake system must be worn with early wear and tear Defective of the hydraulic / return pump can be expected. Another advantage of the invention is the comparatively quiet Actuating the vehicle brake system with the brake booster, its noise in a passenger compartment of a Motor car is not or only quietly perceptible. Also, pressure pulsations or the like are., as used by piston pumps as recirculation pumps are known and can irritate a driver, a brake booster alien.
Die Erfindung ist nicht auf einen elektromotorischen Bremskraftverstärker beschränkt, wie ihn eingangs genannter Stand der Technik offenbart, sondern es ist auch ein elektromagnetischer-, hydraulischer-, pneumatischer-, Unterdruck- oder sonstiger Bremskraftverstärker verwendbar, der steuerbar ist, d. h. dessen Verstärkerkraft unabhängig von einer Muskelkraftbetätigung steuerbar ist. „Steuern” im Sinne der Erfindung schließt ein „Regeln” ein. Zur Ausbildung eines herkömmlichen Unterdruckbremskraftverstärkers als steuerbaren Bremskraftverstärker kann dessen Arbeitskammer mit einem Ventil, beispielsweise einem Magnetventil und wegen der besseren Regelbarkeit einem Proportionalventil, belüftbar ausgebildet werden.The Invention is not on an electric motor brake booster limited, as him mentioned in the prior art but it is also an electromagnetic, hydraulic, pneumatic, vacuum or other brake booster usable, which is controllable, d. H. its amplifier power controllable independently of a muscle power operation is. "Taxes" within the meaning of the invention includes a "rules". To form a conventional Vacuum brake booster as a controllable brake booster can its working chamber with a valve, such as a Solenoid valve and for better controllability a proportional valve, be formed ventilated.
Auch die Feststelleinrichtung der Radbremse ist nicht auf einen Spindeltrieb beschränkt, wie ihn der eingangs erläuterte Stand der Technik offenbart. Die Feststelleinrichtung kann stattdessen beispielsweise eine Rasteinrichtung oder eine Klemmeinrichtung aufweisen, mit der die Radbremse in betätigtem Zustand feststellbar ist. Der festgestellte Zustand sollte vorzugsweise, allerdings nicht zwingend, energielos stabil sein.Also the locking device of the wheel brake is not on a spindle drive limited, as him the stand explained above disclosed in the art. The locking device may instead For example, have a locking device or a clamping device, with the wheel brake in the actuated state lockable is. The detected condition should preferably, but not mandatory, be energy-free stable.
Die Muskelkraftbetätigung des Hauptbremszylinders kann wie im eingangs erläuterten Stand der Technik per Fuß oder per Hand beispielsweise über einen (Hand-)Bremshebel oder in sonstiger Weise erfolgen.The Brake force of the master cylinder can be like in the above-explained prior art by foot or by hand, for example via a (hand) brake lever or done in any other way.
Die Unteransprüche haben vorteilhafte Ausgestaltungen und Weiterbildungen der im Anspruch 1 angegebenen Erfindung zum Gegenstand.The Subclaims have advantageous refinements and developments the invention specified in claim 1 to the subject.
Anspruch
2 sieht einen elektromechanischen Bremskraftverstärker
vor, weil dieser bauartbedingt steuerbar und für die Ausführung
der Erfindung geeignet ist.
Eine Ausgestaltung der Erfindung sieht eine Prüfung der Feststellung der Radbremse in betätigtem Zustand vor. Dazu wird eine oder werden mehrere Größen, evtl. in Abhängigkeit von einer oder mehreren anderen Größen, während der Feststellbetätigung gemessen, deren Verlauf bei einer Fehlfunktion, insbesondere bei einer Nichtfunktion der Feststellung der Radbremse in betätigtem Zustand vom Verlauf bei einer normalen Funktion abweicht. Der bei einer Feststellbetätigung gemessene Verlauf wird zur Prüfung mit dem Normalverlauf verglichen. Es wird beispielsweise der Verlauf des hydraulischen Drucks im Hauptbremszylinder, in einem oder mehreren Radbremszylindern oder an sonstiger Stelle der hydraulischen Fahrzeugbremsanlage in Abhängigkeit von beispielsweise einem Kolbenweg im Hauptbremszylinder während der Feststellbetätigung der Fahrzeugbremsanlage mit dem Bremskraftverstärker gemessen. Bei einem elektromechanischen Bremskraftverstärker mit einem Elektromotor kann ein Drehwinkel des Elektromotors, der dem Kolbenweg im Hauptbremszylinder proportional ist, anstelle des Kolbenwegs gemessen werden. Bei einem elektronisch kommutierten Elektromotor ist der Drehwinkel ohne zusätzlichen Sensor verfügbar. Auch kann der hydraulische Druck in Abhängigkeit von einer Stromaufnahme des Elektromotors des Bremskraftverstärkers gemessen werden. Insbesondere der Druckabfall des Hydraulikdrucks in der Fahrzeugbremsanlage bei einem Rückstellen des Bremskraftverstärkers nach der Betätigung unterscheidet sich, wenn die Feststellung der Radbremse in betätigtem Zustand wirksam ist vom Druckverlauf des Druckabfalls, wenn die Radbremse nicht festgestellt ist. Deswegen kann der Druckverlauf des Druckabfalls zur Prüfung der Wirksamkeit der Feststellung der Radbremse in betätigtem Zustand herangezogen werden. Durch die hydraulische Betätigung ist die Radbremse mechanisch vorgespannt. Wird die mechanische Vorspannung durch die Feststellung der Radbremse mit der Feststelleinrichtung zumindest teilweise aufrecht erhalten, ist der Verlauf des Druckabfalls beim Rückstellen des Bremskraftverstärkers anders als wenn die Radbremse nicht festgestellt ist und sich die mechanische Vorspannung der Radbremse deswegen abbaut.A Embodiment of the invention provides an examination of the finding the wheel brake in the pressed state before. This will be a or become several sizes, possibly in dependence of one or more other sizes while the locking operation measured, the course of a Malfunction, especially in case of non-function of the determination the wheel brake in the actuated state of the course at a normal function deviates. The one with a locking operation measured course becomes the test with the normal course compared. It will, for example, the course of the hydraulic pressure in the master cylinder, in one or more wheel brake cylinders or elsewhere in the hydraulic vehicle brake system in Dependence on, for example, a piston stroke in the master brake cylinder during the parking operation of the vehicle brake system measured with the brake booster. In an electromechanical Brake booster with an electric motor can be a rotation angle of the electric motor, which is proportional to the piston travel in the master cylinder is measured instead of the piston travel. At an electronic Commutated electric motor is the rotation angle without additional Sensor available. Also, the hydraulic pressure in dependence from a current consumption of the electric motor of the brake booster be measured. In particular, the pressure drop of the hydraulic pressure in the vehicle brake system when resetting the brake booster after the actuation differs when the finding the wheel brake in the actuated state is effective from the pressure curve the pressure drop when the wheel brake is not detected. therefore can the pressure gradient of the pressure drop to test the effectiveness the determination of the wheel brake used in the actuated state become. By the hydraulic actuation is the wheel brake mechanically prestressed. Is the mechanical preload by the Determining the wheel brake with the locking device at least partially maintained, is the course of the pressure drop during Resetting the brake booster differently if the wheel brake is not detected and the mechanical Pretension of the wheel brake therefore degrades.
