Description
Die Erfindung betrifft eine Bremsanlage mit mindestens zwei Drucksignalgebern zum Erzeugen von Bremsdrücke wiedergebenden Signalen.The The invention relates to a brake system with at least two pressure sensors for generating brake pressures reproducing signals.
Bei Fahrzeugen mit ESP (Elektronisches Stabilitäts-Programm) Bremsanlagen werden bei einer ESP Regelung Einlassventile geschlossen und somit einzelne Räder vom Fahrer getrennt. Falls der Fahrer während ESP aktiv die Fahrzeugverzögerung erhöhen möchte, muss diese Anforderung von dem Regler erkannt und die Komponenten der Hydraulikeinheit entsprechend geschaltet werden, damit der Bremsdruck in die Radbremse eingesteuert werden kann. Es ist somit wesentlich eine zuverlässige und sichere Erkennung „Fahrer bremst" zu haben.at Vehicles with ESP (Electronic Stability Program) will be braking systems with an ESP regulation inlet valves closed and thus individual Wheels from Driver separately. If the driver wants to increase the vehicle deceleration actively during ESP, then this requirement is recognized by the controller and the components of the Hydraulic unit to be switched accordingly, so that the brake pressure can be controlled in the wheel brake. It is therefore essential a reliable one and safe detection "driver slowing down ".
Auch Assistenzfunktionen wie ACC (Adaptive Cruise Control = Fahrzeuggeschwindigkeitsregelung), AVH (Automatic Vehicle Hold) usw. sind von einer zuverlässigen Information „Fahrer bremst" abhängig, um die Funktion zu deaktivieren bzw. zu aktivieren. In den bekannten Bremsanlagen wird diese Information deswegen redundant aus zwei Signalen gebildet, d.h. aus einem Signal des Bremslichtschalters BLS und einem Signal des THZ (Tandem-Haupt-Zylinder) Sensors. Beide Signale werden verwendet um „Fahrer bremst" zu detektieren.Also Assistance functions such as ACC (Adaptive Cruise Control), AVH (Automatic Vehicle Hold) etc. are from a reliable driver information brakes "dependent, um disable or enable the feature. In the known Brake systems, this information is therefore redundant from two Signals are formed, i. from a signal from the brake light switch BLS and a signal from the THZ (tandem master cylinder) sensor. Both Signals are used to "driver slows down "to detect.

Der Erfindung liegt die Aufgabe zugrunde, eine Bremsanlage an zugeben, die ohne das Signal des Bremslichtschalters eine sichere und zuverlässige Erkennung einer Fahrerbremsung ermöglicht.Of the Invention is based on the object to admit a brake system, which without the signal of the brake light switch safe and reliable detection a driver's braking allows.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass anhand von mindestens zwei Signalen der Drucksignalgeber festgestellt wird, ob der Fahrer bremst, wobei die Bremsanlage keinen Bremslichtschalter aufweist.According to the invention this Task solved by that determined by at least two signals of the pressure signal generator whether the driver brakes, with the brake system no brake light switch having.
Diese Aufgabe wird auch durch ein gattungsgemäßes Verfahren zum Ermitteln einer Fahrerbremsung ohne Bremslichtschalter gelöst, indem die Fahrerbremsung mittels mindestens zwei Drucksignalen festgestellt wird.These Task is also determined by a generic method for determining a driver's braking without brake light switch solved by the driver's braking is detected by at least two pressure signals.
In neueren Bremsanlagen mit einem Druckssignalgeber des Hauptbremszylinders und einem oder mehreren Raddrucksignalgebern kann eine Fahrerbremsung über mehrere Drucksignalgeber (z.B. 5) detektiert werden, wenn keine Regelung oder keine Assistenzfunktion aktiv ist. Dabei kann das Signal eines dem Hauptbremszylinder zugeordneten Drucksensors über die Signale der Raddrucksensoren und/oder über anderweitig generierte Drucksignale umfangreich plausibilisiert werden, so dass ein unbemerkter Defekt im Drucksensor des Hauptbremszylinders praktisch ausgeschlossen werden kann. Andersweitig generierte Drucksignale können z.B. durch jedem Bremskreis zugeordnete Drucksignalgeber ermittelt werden, die den Hauptbremszylinderdruck redundant erfassen, oder durch einen dem Hauptbremszylinder zugeordneten Drucksignalgeber, der ein elektrisch redundantes Signal erzeugt. Durch dieses erhöhte Maß an Redundanz besteht die Möglichkeit auf den Bremslichtschalter Schalter zu verzichten und ein Kostenersparnis pro Fahrzeug zu erzielen.In newer brake systems with a pressure transducer of the master cylinder and one or more Raddrucksignalgebern a driver's braking over several Pressure sensors (e.g., 5) are detected when no control or no assistance function is active. The signal of a the master cylinder associated pressure sensor via the Signals of the wheel pressure sensors and / or otherwise generated Pressure signals are extensively plausibilized, leaving an unnoticed Defective in the pressure sensor of the master cylinder practically impossible can be. Differently generated pressure signals may e.g. determined by each brake circuit associated pressure signal generator, which detect the master cylinder pressure redundant, or by a the master cylinder associated pressure sensor, which is an electrical generated redundant signal. This increased level of redundancy makes it possible to dispense with the brake light switch switch and a cost savings to achieve per vehicle.
