Abstract
Description
Die Erfindung betrifft eine Bremsbetätigungseinheit zur Betätigung einer Kraftfahrzeugbremsanlage vom Typ „Brake-by-wire", die aus
- • einem sowohl mittels eines Bremspedals als auch mittels einer elektronischen Steuereinheit fahrerwunschabhängig betätigbaren Bremskraftverstärker, wobei Mittel zur Entkopplung einer kraftübertragenden Verbindung zwischen dem Bremspedal und dem Bremskraftverstärker in der Betriebsart „Brake-by-wire" vorgesehen sind,
- • Mitteln zum Erfassen eines Fahrerverzögerungswunsches,
- • sowie einem mit dem Bremspedal zusammenwirkenden Pedalwegsimulator besteht, durch den in der Betriebsart „Brake-by-wire" eine auf das Bremspedal wirkende Rückstellkraft unabhängig von einer Betätigung des Bremskraftverstärkers simulierbar ist und der in der Betriebsart „Brake-by-wire" bei der Entkopplung der kraftübertragenden Verbindung zwischen dem Bremspedal und dem Bremskraftverstärker zuschaltbar und außerhalb der Betriebsart „Brake-by-wire" abschaltbar ist, wobei der Pedalwegsimulator durch eine Simulatorfeder gebildet ist, die wirkungsmäßig zwischen einem mit dem Bremspedal verbundenen Kraftübertragungshebel und einem Simulatorgehäuse angeordnet ist und die mit Mitteln zur Erzeugung einer Hysterese derart zusammenwirkt, dass mit steigendem Hub des Pedalwegsimulators zusätzlich zur Kraft der Simulatorfeder Reibkräfte erzeugt werden, die der am Bremspedal wirkenden Betätigungskraft entgegen wirken.
- A brake booster which can be actuated both by means of a brake pedal and by means of an electronic control unit, wherein means are provided for decoupling a force-transmitting connection between the brake pedal and the brake booster in the "brake-by-wire" operating mode,
- Means for detecting a driver deceleration request,
- • As well as cooperating with the brake pedal pedal travel simulator, through which in the operating mode "brake-by-wire" acting on the brake pedal restoring force is independent of an operation of the brake booster simulated and in the operating mode "brake-by-wire" in the Decoupling of the force-transmitting connection between the brake pedal and the brake booster can be switched off and outside the operating mode "brake-by-wire" can be switched off, the pedal travel simulator is formed by a simulator, which is operatively arranged between a connected to the brake pedal power transmission lever and a simulator housing and the cooperates with means for generating a hysteresis such that in addition to the force of the simulator spring frictional forces are generated with increasing stroke of the pedal travel simulator, which counteract the force acting on the brake pedal actuating force.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Betätigungseinheit der eingangs genannten Gattung weiter zu entwickeln, deren Pedalsimulator den eingeschränkten Bauraumverhältnissen im Fußraum des Fahrzeugführers angepasst ist.It is therefore an object of the present invention, an actuating unit to further develop the genus mentioned above, the pedal simulator the restricted space conditions in the footwell of the driver is adjusted.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Simulatorfeder als Flachbiegefeder ausgebildet ist und eine Bremspedallagerung zumindest teilweise umgreift.These Task is inventively characterized solved, that the simulator spring is designed as a flat spiral spring and a brake pedal bearing at least partially surrounds.
Bei einer vorteilhaften Weiterbildung ist vorgesehen, dass zum Umgreifen der Bremspedallagerung das Bremspedal mindestens zwei Ausnehmungen aufweist, durch die sich die Enden der Flachbiegefeder hindurch erstrecken. Durch diese Maßnahmen wird erreicht, dass das Reibglied des Pedalwegsimulators nahe an der Bremspedallagerung angeordnet werden kann. Dadurch kann das Gehäuse des Pedalwegsimulators wesentlich kleiner ausgebildet werden und besser an die beschränkten Bauraumverhältnisse angepasst werden.at an advantageous development is provided that for grasping the brake pedal bearing the brake pedal at least two recesses has, through which the ends of the flat spiral spring through extend. Through these measures is achieved that the friction member of the pedal travel simulator close to the brake pedal storage can be arranged. This can do that casing the pedal travel simulator are designed to be much smaller and better to the limited installation space conditions be adjusted.
Bei einer anderen vorteilhaften Weiterbildung Erfindungsgegenstandes dass die Flachbiegefeder in ihrem maximalen Biegemomentenbereich in zwei näherungsweise parallele Abschnitte geteilt ist.at Another advantageous development of the subject invention that the flat spiral spring in their maximum bending moment range in two approximate is divided into parallel sections.
Eine andere besonders vorteilhafte Ausführung des Erfindungsgegenstandes besteht darin, dass dass ein Vorsprung am Bremspedal ausgebildet ist, der mit dem Simulatorgehäuse derart zusammenwirkt, dass ein Endanschlag am Ende des Simulatorhubes für das Bremspedal realisiert wird.A Another particularly advantageous embodiment of the subject invention is that a projection on the brake pedal is formed, the one with the simulator housing cooperates such that an end stop at the end of Simulatorhubes for the Brake pedal is realized.
Eine weitere vorteilhafte Ausführung sieht vor, dass als Mittel zum Erfassen eines Fahrerverzögerungswunsches ein vorkalibrierter Drehwinkelsensor vorgesehen ist, der die Bewegung des Bremspedals erfasst. Dabei ist vorgesehen, dass die Verbindung zwischen einem Aufnehmer des Drehwinkelsensors und dem Bremspedal erst dann realisiert wird, wenn sich das Bremspedal in seiner Ruhestellung befindet.A further advantageous embodiment provides that as a means for detecting a driver deceleration request a pre-calibrated rotation angle sensor is provided which controls the movement of the brake pedal detected. It is envisaged that the connection between a transducer of the rotation angle sensor and the brake pedal is only realized when the brake pedal in its rest position located.
