Die Erfindung betrifft ein Antiblockierregelsystem mit den Merkmalen desOberbegriffs des Anspruchs 1.The invention relates to an anti-lock control system with the Features of the preamble of claim 1.
Ein solches Antiblockierregelsystem ist bekannt, so z.B. aus der DE-OS 31 26 102.Such an anti-lock control system is known, e.g. DE-OS 31 26 102.
Die derzeitig bekannten Antiblockierregelsysteme schalten im Störungsfall die ABS-Funktion ab. Dann ist die normale Brem- η se vorwirksam. Wegen der notwendigen Fahrstabilität im vorgenannten Fehlerfall verwenden viele Fahrzeuge, insbesondere frontgetriebene Fahrzeuge, für die Hinterachse einen Bremsdruckminderer. Da bei abgeschaltetem ABS die Vorderachse vor der Hinterachse instabil wird, steigert der Fahrer meistens beim Blockieren der Vorderachse den Bremsdruck nicht weiter, so daß die blockierfreie Hinterachse dann die Fahrstabilität sichert. Eine entsprechende Auslegung der Bremsen ist in vielen Ländern vom Gesetzgeber vorgeschrieben.The currently known anti-lock control systems switch in Deactivate the ABS function in the event of a malfunction. Then the normal brake η se pre-effective. Because of the necessary driving stability in the aforementioned In the event of a fault, many vehicles, especially front-wheel drive vehicles, use a brake pressure reducer for the rear axle. Since the front axle in front of the rear axle becomes unstable when the ABS is switched off, the driver usually increases the speed When the front axle is locked, the brake pressure is no longer applied, so that the locking-free rear axle then improves driving stability secures. A corresponding design of the brakes is required by law in many countries.
Die erfindungsgemäße Verwendung eines nicht gebremsten Hinterrads, z.B. durch ein stromlos gesperrtes ABS-Ventil in einem Hinterachskreis, vorzugsweise bei diagonaler Bremskreisaufteilung, verhindert im Störungsfall des Antiblockierreglers,The inventive use of a non-braked rear wheel, E.g. through a currentless blocked ABS valve in a rear axle circuit, preferably with diagonal brake circuit distribution, prevents in the event of a malfunction of the anti-lock controller,

daß das Hinterrad Bremsdruck erhält. Damit ist eine Blockierung des Rads ausgeschlossen. Bei diagonaler Bremskreisaufteilung, welche besonders vorteilhaft geeignet ist zur Ausführung des Lösungsgedankens, bremst also im Störungsfall ein Hinterrad nicht, was eine geringfügige Reduzierung der Bremswirkung zugunsten der Fahrstabilität zur Folge hat. In Anbetracht der hohen Zuverlässigkeit von ABS-Systemen ist diese Einschränkung statthaft.that the rear wheel receives braking pressure. This prevents the wheel from locking. With diagonal brake circuit distribution, which is particularly advantageously suitable for implementing the solution idea, so brakes a rear wheel in the event of a malfunction not, which results in a slight reduction in the braking effect in favor of driving stability. Considering the high reliability of ABS systems is this limitation permissible.
Es sind seit längerem auch Fahrzeuge mit einer Bremskreis- aufteilung in Produktion bei denen je ein Bremskreis auf zwei Vorderräder und ein Hinterrad wirkt und welche im Fehlerfan dasselbe Bremsergebnis bringen. For a long time, there have also been vehicles with a brake circuit distribution in production in which one brake circuit acts on two front wheels and one rear wheel and which bring the same braking result in the error fan.
Entsprechend dem Lösungsvorschlag der Erfindung wird die Magnetventil anordnung über die Auswerteschaltung eingeschaltet, ist also während der gesamten Fahrt oder auch nur während des Bremsvorgangs erregt und gibt somit dem Fahrzeug die volle Bremswirkung. Durch diese Venti1 schaltung kann auf den Druckminderer für die Hinterachse verzichtet werden; insbesondere bei Fahrzeugen mit diagonaler Bremskreisaufteilung und zwei Druckminderern stellen diese einen nennenswerten Aufwand dar.According to the proposed solution of the invention, the solenoid valve arrangement is switched on via the evaluation circuit, is therefore excited during the entire journey or only during the braking process and thus gives the vehicle the full braking effect. This valve circuit can open the pressure reducer for the rear axle can be dispensed with; especially for vehicles with diagonal brake circuit division and two pressure reducers, these represent a considerable effort.

Im Bremskreis II ist eine übliche Ventilanordnung eingeschaltet, die in stromlosem Zustand durchlässig ist. Im Gegensatz dazu ist die Ventilanordnung 3 im Bremskreis I in stromlosem Zustand geschlossen. Der Radbremszylinderanschluß ist mit einem drucklosen Rücklauf R verbunden. .Die zweite Schaustellung der Ventileinrichtung 3 dient der Druckkonstanthaltung in der Radbremse. In der dritten Schaltstellung ist ein freier Durchgang vom Hauptbremszylinder 5 zum Radbremszylinder bei geschlossenem Rücklauf gegeben. Diese Ventilanordnung 3 wird von einer Auswerteschaltung 4 eingeschaltet und ist während der normalen Fahrt erregt. Zur Einsparung des Stromverbrauchs kann die Einschaltung des Ventils in die 3. Schaltstellung ohne ABS-Funktion auch über den Bremslichtschalter BS erfolgen. Bei ABS-Betrieb wechseln die Schaltstellungen 1-3 zwecks Druckabbau, Druckaufbau und Konstanthaltung. Bei ABS-Abschaltung gehen die Ventilanordnungen 3 und 4 in die Schaltstellung 1, in der das Rad 2 gebremst werden kann, jedoch nicht das Rad 1.In the brake circuit II, a conventional valve arrangement is switched on, which is permeable in the de-energized state. In contrast for this purpose, the valve arrangement 3 in the brake circuit I is closed in the de-energized state. The wheel brake cylinder connection is with a pressureless return R connected. The second display of the valve device 3 is used to keep the pressure constant in the wheel brake. In the third switch position is a Free passage from the master cylinder 5 to the wheel brake cylinder given when the return is closed. This valve arrangement 3 is switched on by an evaluation circuit 4 and is aroused during normal driving. To save power consumption, the valve can be switched on in the 3. Switch position without ABS function also via the brake light switch BS take place. During ABS operation, the switch positions 1-3 change for the purpose of pressure reduction, pressure build-up and maintenance. When the ABS is switched off, the valve assemblies 3 and 4 go into switching position 1, in which the wheel 2 is braked but not wheel 1.
Fig. 2 zeigt anstelle des Dreistellungsventils 3 eine Ventilkonfiguration, welche aus zwei Zweistellungsventilen 5 und 7 besteht, welche ebenfalls dem Stand der Technik entsprechen. Bei dieser Ventilkonfiguration wird das Ventil 7 von der Auswerteschaltung 4 im Normalfall eingeschaltet. (Stellung 2). Im Störungsfall ist die Verbindung vom Hauptbremszylinder 5 zum Radbremszylinder des Rads 1 gesperrt (Stellung 1). Der Radzylinder ist dann mit dem Rücklauf R verbunden. Die ABS-Funktion wird durch die kombinierte Ansteuerung beider Ventile 6 und 7 erreicht:FIG. 2 shows a valve configuration instead of the three-position valve 3, which consists of two two-position valves 5 and 7 exists, which also correspond to the state of the art. With this valve configuration, the valve 7 is controlled by the evaluation circuit 4 normally switched on. (Position 2). In the event of a malfunction, the connection from the master brake cylinder 5 locked to the wheel brake cylinder of wheel 1 (position 1). The wheel cylinder is then connected to the return line R. The ABS function is achieved by the combined control of both valves 6 and 7:
