Description
Die Erfindung betrifft ein Verfahren zur Überwachung von Drucksensoren in Bremsanlagen eines Kraftfahrzeugs und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for monitoring pressure sensors in brake systems of a motor vehicle and to an apparatus for carrying out the method.
Bremsanlagen für Kraftfahrzeuge dienen u. a. zur Kontrolle der Fahrstabilität des Fahrzeugs.Braking systems for motor vehicles serve u. a. to control the driving stability of the vehicle.
Unter dem Begriff Fahrstabilitätsregelung vereinigen sich eine Vielzahl von Prinzipien zur Beeinflussung des Fahrverhaltens eines Fahrzeugs mittels vorgebbarer Drücke in einzelnen Radbremsen und mittels Eingriff in das Motormanagement des Antriebsmotors. Dabei kann es sich um eine Bremsschlupfregelung (ABS), welche während eines Bremsvorgangs das Blockieren einzelner Räder verhindern soll, um eine Antriebsschlupfregelung (ASR), welche das Durchdrehen der angetriebenen Räder verhindert, um eine elektronische Bremskraftverteilung (EBV), welche das Verhältnis der Bremskräfte zwischen Vorder- und Hinterachse des Fahrzeugs regelt, sowie um eine Giermomentenregelung (GMR), welche für stabile Fahrzustände beim Durchfahren einer Kurve sorgt, handeln. Eine Giermomentenregelung ist auch unter dem Begriff elektronisches Fahrstabilitätsprogramm (ESP) bekannt. Eine Möglichkeit, eine Fahrstabilitätsregelung mit einem elektronischen Fahrstabilitätsprogramm zu realisieren, besteht darin, zunächst ein Zusatzgiermoment zu berechnen und dieses in eine Ansteuerung der Bremsvorrichtungen der einzelnen Räder umzusetzen. Zum Beispiel kann aus dem Wert für das Zusatzgiermoment mittels einer Verteilungslogik die in den Radbremsen einzustellenden Drücke errechnet werden. Über einen im Bremskreis vorgesehenen Drucksensor werden die Ist-Druckwerte, die der Fahrer während der Fahrstabilitätsregelung in die Bremsleitung einsteuert, erfasst und in das elektronische Fahrstabilitätsprogramm rückgekoppelt. Eine plausible Regelung setzt voraus, dass der Drucksensor den vom Fahrer eigesteuerten Ist-Druckwert korrekt wiedergibt. Dies ist bei elektronischen Fahrstabilitätsprogrammen (ESP) in extremen Fahrsituationen, in denen eine Regelabweichung schon innerhalb einer sehr kurzen Zeit ausgeregelt werden muss, besonders wichtig. Aus diesem Grunde muss bei einem elektronischen Fahrstabilitätsprogramm auch der Drucksensor ständig überwacht werden. Bekannte Bremsanlagen stellen dies über eine Plausibilitätsüberwachung sicher, die die Fahrzeugverzögerung über den Bremsdruck betrachten. Dies hat den Nachteil, dass sehr hohe Schwellenwerte für die Fahrzeugverzögerung notwendig sind, um zum Beispiel nicht bereits bei einer Verzögerung durch externe Fahrwiderstände, wie sie durch eine Bergauffahrt oder im Tiefschnee erfolgen kann, eine Fehlermeldung zu generieren. Ein Überschreiten dieser Schwellenwerte wird im Normalfahrbetrieb unter Umständen nicht oder nur sehr schwer erreicht.The term driving stability control unites a variety of principles for influencing the driving behavior of a vehicle by means of specifiable pressures in individual wheel brakes and by engaging in the engine management of the drive motor. This can be a brake slip control (ABS), which is intended to prevent the locking of individual wheels during a braking operation, a traction control (ASR), which prevents the spinning of the driven wheels, an electronic brake force distribution (EBV), which determines the ratio of braking forces between the front and rear axle of the vehicle, as well as a yaw moment control (GMR), which ensures stable driving conditions when driving through a curve act. A yaw moment control is also known as electronic driving stability program (ESP). One way to realize a driving stability control with an electronic driving stability program, is to first calculate a Zusatzgiermoment and implement this in a control of the braking devices of the individual wheels. For example, from the value for the additional yaw moment by means of a distribution logic, the pressures to be set in the wheel brakes can be calculated. By means of a pressure sensor provided in the brake circuit, the actual pressure values that the driver controls during the driving stability control in the brake line are detected and fed back into the electronic driving stability program. A plausible regulation presupposes that the pressure sensor correctly reproduces the actual pressure value controlled by the driver. This is particularly important in electronic driving stability programs (ESP) in extreme driving situations in which a control deviation must be corrected within a very short time. For this reason, in an electronic driving stability program and the pressure sensor must be constantly monitored. Known brake systems ensure this via a plausibility monitoring, which consider the vehicle deceleration via the brake pressure. This has the disadvantage that very high threshold values for the vehicle deceleration are necessary in order, for example, not to generate an error message even in the event of a deceleration due to external driving resistances, such as can occur through uphill driving or in deep snow. Exceeding these threshold values may not or only with great difficulty be achieved in normal driving.
Man hat weiterhin bereits eine redundante Überprüfung durch einen zweiten Drucksensor realisiert. Eine derartige Lösung ist jedoch mit hohen Kosten verbunden.It has also been realized a redundant check by a second pressure sensor. However, such a solution is associated with high costs.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Überwachung von Drucksensoren zu schaffen, das/die eine insbesondere für ein elektronisches Fahrstabilitätsprogramm (ESP) für Fahrzeuge kostengünstige Funktionsüberprüfung ermöglicht.The invention is therefore based on the object of providing a method and a device for monitoring pressure sensors, which enables a cost-effective functional check, in particular for an electronic driving stability program (ESP) for vehicles.

- e) comparing the evaluated pressure signal with a predetermined threshold value and / or a predetermined course of the pressure signal and generating an error message if the pressure signal does not reach the threshold value or a correction value if the pressure signal does not correspond to the predetermined course
Desweiteren ist es vorteilhaft, dass das Verfahren ein Teil eines elektronischen Fahrstabilitätsprogrammes (ESP) ist.Furthermore, it is advantageous that the method is part of an electronic driving stability program (ESP).
Es ist zweckmäßig, dass das Verfahren außerhalb einer Fahrstabilitätsregelung (ABS, ASR, ESP und dergleichen) abläuft und das elektronische Fahrstabilitätsprogramm (ESP) deaktiviert, wenn die Fehlermeldung (F) erzeugt wird.It is expedient that the method runs outside a driving stability control (ABS, ASR, ESP and the like) and deactivates the electronic driving stability program (ESP) when the error message (F) is generated.
Es ist weiterhin zweckmäßig, dass das Verfahren außerhalb einer Fahrstabilitätsregelung (ABS, ASR, ESP und dergleichen) abläuft und den Drucksensor bezüglich einer Nullpunktabweichung korrigiert, wenn ein Korrekturwert erzeugt wird.Furthermore, it is expedient for the method to run outside a driving stability control (ABS, ASR, ESP and the like) and to correct the pressure sensor for a zero deviation when a correction value is generated.
Um eine Einbremsung während der Überwachung der Drucksensoren in die Bremsanlage zu ermöglichen, ist es vorteilhaft, dass bei einer zweikreisigen Bremsanlage der Systemdruck nur in einem der Bremskreise erzeugt wird.In order to enable a braking during the monitoring of the pressure sensors in the brake system, it is advantageous that in a dual-circuit brake system, the system pressure is generated only in one of the brake circuits.
