Description
Die Erfindung betrifft ein Verfahren zum Unterstützen einer elektrischen Parkbremse eines Fahrzeugs in Betriebssituationen, in denen die von der Parkbremse aufgebrachte Spannkraft nicht ausreicht, um das Fahrzeug im Stillstand zu halten und Bremskreise einer hydraulischen Betriebsbremse zusätzlich aktiviert werden, indem mittels eines Druckmittels in den Hinterachsradbremsen Unterstützungsbremsdruck aufbaut wird.The The invention relates to a method for assisting an electric parking brake of a vehicle in operating situations in which the of the parking brake applied clamping force is insufficient to stop the vehicle to hold and brake circuits of a hydraulic service brake additionally activated be by means of a pressure medium in the Hinterachsradbremsen Support brake pressure is built up.
Im Allgemeinen ist die von elektrischen Parkbremsen aufgebrachte Spannkraft ausreichend, um ein Fahrzeug sicher im Stillstand zu halten. In kritischen Betriebssituationen ist jedoch eine hydraulische Unterstützung der elektrischen Parkbremse durch die Betriebsbremse erforderlich, um die notwendige Spannkraft aufzubringen.in the In general, the applied by electric parking brakes clamping force sufficient to keep a vehicle safely at a standstill. In However, critical operating situations is a hydraulic support of the electric parking brake required by the service brake to to apply the necessary clamping force.

dem zuvor beschriebenen Verfahren muss das Umschaltventil
Daher kann beim Anhalten an kritischen Steigungen und/oder bei hohen Beladungssituationen des Fahrzeugs, in denen der Fahrer hinreichend stark bremst und wo ein Unterstützungsbremsdruck eigentlich notwendig wird, dieser Unterstützüngsbremsdruck nicht sicher gewährleistet werden.Therefore can stop at critical slopes and / or in high loading situations Vehicle in which the driver brakes sufficiently strong and where a Support brake pressure actually becomes necessary, this assist brake pressure not sure assured become.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Unterstützen einer elektrischen Parkbremse durch einen Unterstützungsbremsdruck in den Hinterradbremsen eines Fahrzeugs zu schaffen, das bei kritischen Betriebssituationen, die ein Öffnen des Umschaltventils der Betriebsbremse nicht mehr erlauben, dennoch einen Aufbau eines Unterstützungsbremsdrucks der Parkbremse ermöglicht.Of the Invention is based on the object, a method for supporting a electric parking brake by a backup brake pressure in the rear wheel brakes of a vehicle to be used in critical operational situations, the one opening the changeover valve of the service brake no longer allow, nevertheless a structure of an assist brake pressure the parking brake allows.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass das Druckmittel den Vorderradbremsen entnommen und zum Aufbau des Unterstützungsbremsdrucks in die Hinterachsradbremsen transferiert wird.According to the invention this Task solved by that the pressure medium is taken from the front brakes and to build the backup brake pressure is transferred to the Hinterachsradbremsen.
Vorteilhaft kann dadurch, dass das Druckmittel den Vorderradbremsen entnommen und zum Aufbau des Unterstützungsbremsdrucks in die Hinterachsradbremsen transferiert wird, die Parkbremsfunktion auch in der genannten kritischen Betriebssituation sichergestellt werden. Die Parkbremse kann kleiner dimensioniert werden.Advantageous can by the fact that the pressure medium removed from the front brakes and to build up the assist brake pressure is transferred to the Hinterachsradbremsen, the parking brake function also ensured in the mentioned critical operating situation become. The parking brake can be made smaller.
Ferner wird die Aufgabe auch durch eine erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens nach einem der Verfahrensansprüche gelöst, wobei eine Bremsanlage mit diagonal aufgeteilten Bremskreisen vorgesehen ist, die Steuerungsmittel zum Aufbau vom Bremsdruck in den Radbremsen und einen Niederdruckspeicher sowie einen Drucksensor im Bremskreis enthält und wobei die Steuerungsmittel von einem elektronischen Regler angesteuert werden können. Dabei schaltet der elektronische Regler die Steuermittel so, dass in Abhängigkeit von dem in der Bremsanlage vorhandenen Bremsdruck der in den Vorderradbremsen vorhandene Bremsdruck in den Niederdruckspeicher und gleichzeitig von der Pumpe in die Hinderradbremsen gefördert wird.Further The object is also achieved by a device according to the invention for carrying out the method according to one of the method claims solved, wherein a brake system provided with diagonally split brake circuits is the control means to build up the brake pressure in the wheel brakes and a low-pressure accumulator and a pressure sensor in the brake circuit contains and wherein the control means are driven by an electronic controller can be. The electronic controller switches the control means so that in dependence of the brake pressure present in the brake system in the front brakes existing brake pressure in the low-pressure accumulator and at the same time is promoted by the pump in the Hinderradbremsen.
Dazu wird/werden vorteilhaft:
- • Die Einlassventile der Vorderachse geschlossen
- • Die Trennventile geschlossen
- • Das Volumen der Vorderachse wird über die Auslassventile bedarfsgerecht in den Niederdruckspeicher abgebaut und
- • mit der Pumpe in die Hinterradsättel gepumpt.
- • The inlet valves of the front axle are closed
- • The isolation valves are closed
- • The volume of the front axle is reduced via the exhaust valves as needed in the low-pressure accumulator and
- • Pumped into the rear wheels with the pump.
Dies kann insbesondere dann getan werden, wenn man erkennt, dass eine kritische Betriebssituation es erfordert.This can be done especially if one recognizes that one critical operating situation requires it.
Oder man wählt die Methode bewusst, um den Fahrerfuß vom Pulsieren beim Druckaufbau zu entkoppeln.Or you choose The method is aware of the driver's foot from pulsing during pressure build-up to decouple.
Vorteilhaft wird das Druckmittel den Vorderradbremsen in Abhängigkeit von dem in der Betriebsbremse herrschenden Bremsdruck entnommen. Dadurch wird sichergestellt, dass ein Unterstützungsbremsdruck in den Hinterradbremsen bei kritischen Be triebssituationen sichergestellt wird, ohne dass ein Öffnen des Umschaltventils erforderlich ist.Advantageous the pressure medium is the front brakes depending on the in the service brake prevailing brake pressure taken. This will ensure that a support brake pressure ensured in the rear brakes in critical Be operating situations will, without any opening the changeover valve is required.
Empirische Untersuchungen ergaben, dass der in der Betriebsbremse herrschenden kritischen Bremsdruck in Abhängigkeit von Kennzahlen wiedergegeben werden kann, die die Spulentemperatur des Umschaltventils und/oder die Bordnetzspannung darstellen. Dabei besteht eine Korrelation zwischen dem kritischen Bremsdruck und der Spulentemperatur des Umschaltventils sowie der Bordnetzspannung. Die Werte für die Spulentemperatur des Umschaltventils und der Bordnetzspannung, bei denen ein Öffnen des Umschaltventils nicht mehr möglich ist, können in einem Kennfeld aufgeführt werden.empirical Investigations showed that the ruling in the service brake critical brake pressure depending can be reproduced by key figures that the coil temperature represent the changeover valve and / or the vehicle electrical system voltage. there there is a correlation between the critical brake pressure and the coil temperature of the changeover valve and the vehicle electrical system voltage. The values for the coil temperature of the changeover valve and the vehicle electrical system voltage, where an opening the change-over valve is no longer possible, can listed in a map become.
Weiterhin ist es vorteilhaft, dass die Bremskreise diagonal aufgeteilt sind.Farther It is advantageous that the brake circuits are divided diagonally.
Dadurch dass der Betriebsbremsdruck überwacht und in einen kritischen Betriebsbremsdruck und einen unkritischen Betriebsbremsdruck, bei dem ein Öffnen des Umschaltventils sicher gewährleistet ist, unterteilt wird, kann unterhalb des in der Betriebsbremse herrschenden kritischen Bremsdrucks das Druckmittel einem Hauptzylinder entnommen und zum Aufbau des Unterstützungsbremsdrucks in die Hinterachsradbremsen transferiert werden.Thereby that monitors the service brake pressure and in a critical service brake pressure and a non-critical Service brake pressure at which an opening the switching valve is ensured is subdivided below the ruling in the service brake Critical brake pressure, the pressure medium removed from a master cylinder and to build up the assist brake pressure be transferred to the Hinterachsradbremsen.
