Description

Bremspedal Brake pedal
Beschreibung description
Die Erfindung betrifft ein Bremspedal für ein Kraftfahrzeug, umfassend einen Pedal arm, der im Bereich seines ersten Endes drehbar in dem Kraftfahrzeug gelagert ist, und eine Bedienplatte, die an einem dem ersten Ende entgegengesetzten zweiten Ende des Pedalarms angeordnet ist. The invention relates to a brake pedal for a motor vehicle, comprising a pedal arm which is rotatably mounted in the motor vehicle in the region of its first end, and a control panel which is arranged at a second end of the pedal arm opposite the first end.
Solche Bremspedale sind an sich bestens bekannt und werden in Kraftfahrzeugen verbaut, damit ein Fahrer das Kraftfahrzeug abbremsen und gegebenenfalls zum Still stand bringen kann. Bei bisher eingesetzten Bremspedalen wird bei deren Betätigung ein Kolben in einem Zylinder so bewegt, dass in einer zugehörigen hydraulischen Bremsanlage ein Bremsdruck entsprechend einer auf das Bremspedal ausgeübten Kraft aufgebaut wird; bei pneumatischen Systemen, die vorzugsweise in Lastkraftwa gen und Omnibussen verbaut werden, wird in der Bremsanlage ein Luftdruck entspre chend z.B. verringert. Such brake pedals are well known per se and are installed in motor vehicles so that a driver can brake the motor vehicle and, if necessary, bring it to a standstill. In brake pedals used up to now, when they are operated, a piston in a cylinder is moved in such a way that a brake pressure is built up in an associated hydraulic brake system in accordance with a force exerted on the brake pedal; In the case of pneumatic systems, which are preferably installed in trucks and buses, the air pressure in the brake system is reduced accordingly, for example.
Im Kraftfahrzeugbau besteht die Tendenz, möglichst viele Systeme mittels Elektronik zu überwachen und zu steuern. Auch Bremsanlage sollen derart betätigt werden. Hierfür muss das Bremspedal mit mindestens einem Sensor ausgestattet sein, damit die Bremskraft von der Elektronik entsprechend der Bedienung und/oder den Bedürf nissen gesteuert werden kann. In motor vehicle construction there is a tendency to monitor and control as many systems as possible using electronics. The brake system should also be operated in this way. For this, the brake pedal must be equipped with at least one sensor so that the braking force can be controlled by the electronics according to the operation and / or needs.
Aus der CN 103 481 878 A ist ein Bremspedal bekannt, bei dem ein Drehwinkelsensor zur Bestimmung eines Drehwinkels eines Pedalarms vorgesehen ist. Eine Anordnung zur Simulation des Verhaltens eines herkömmlichen Bremspedals ist über einen Stö ßel angeschlossen. Weiterhin ist in einer Bedienplatte, die aus zwei Einzelplatten zu sammengefügt ist und einen Hohlraum umschließt, ein Dehnungsmessstreifen zur Bestimmung einer Bremskraft angeordnet. Weitere Einzelheiten zu der Bedienplatte und der Bremskraftbestimmung sind nicht angegeben. Dehnungsmessstreifen sind relativ aufwändig sowie entsprechend teuer und daher für große Serien nicht geeignet. From CN 103 481 878 A, a brake pedal is known in which a rotation angle sensor is provided for determining a rotation angle of a pedal arm. An arrangement for simulating the behavior of a conventional brake pedal is connected via a tappet. Furthermore, a strain gauge for determining a braking force is arranged in a control panel, which is assembled from two individual panels and encloses a cavity. Further details on the control panel and the determination of the braking force are not given. Strain gauges are relatively complex and correspondingly expensive and therefore not suitable for large series.
Es ist daher die Aufgabe der Erfindung, ein Bremspedal zu schaffen, bei dem Mittel zur Bestimmung der Bremskraft einfach und preiswert gefertigt werden können. It is therefore the object of the invention to create a brake pedal in which means for determining the braking force can be manufactured simply and inexpensively.
Die Aufgabe ist dadurch gelöst, dass die Bedienplatte kippbar an dem zweiten Ende befestigt ist und dass ein Positionssensor angeordnet ist zur Bestimmung eines lich ten Abstandes zwischen der Bedienplatte und einer Verlängerung, die an dem zweiten Ende des Pedalarms angeordnet ist. Die Kippbarkeit der Bedienplatte bewirkt, dass diese bei Betätigung des Bremspedals um eine Achse gekippt wird, die zwischen dem zweiten Ende und der Bedienplatte liegt. Hierbei ist ein Widerstand gegen das Kippen festgelegt, damit ein Kippwinkel in Abhängigkeit von einer auf die Bedienplatte ausge übten Kraft definiert ist und somit eine feste, vorzugsweise lineare Beziehung zwi schen der Kraft und dem Kippwinkel besteht. Eine entsprechende Bewegung eines freien Endes der Bedienplatte wird mittels des Positionssensors bestimmt und für eine Plausibilitätsprüfung eines Verhältnisses„Bremspedal-Winkel zu Kraft, die auf das Bremspedal wirkt“ genutzt werden. Hierdurch kann z.B. eine mechanische Blockie rung des Bremspedals durch einen Fremdkörper ermittelt werden. Der Positions sensor kann einfach und preiswert ausgeführt sein, so dass das Bremspedal insge samt kostengünstig gefertigt werden kann. The object is achieved in that the control panel is tiltably attached to the second end and in that a position sensor is arranged to determine a distance between the control panel and an extension which is arranged at the second end of the pedal arm. The tiltability of the control panel means that when the brake pedal is actuated, it is tilted about an axis that lies between the second end and the control panel. Here, a resistance to tilting is defined so that a tilt angle is defined as a function of a force exerted on the control panel and thus there is a fixed, preferably linear relationship between the force and the tilt angle. A corresponding movement of a free end of the control panel is determined by means of the position sensor and used for a plausibility check of the ratio “brake pedal angle to force acting on the brake pedal”. In this way, for example, a mechanical blockage of the brake pedal by a foreign body can be determined. The position sensor can be designed simply and inexpensively so that the brake pedal can be manufactured inexpensively overall.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung. The subclaims relate to the advantageous embodiment of the invention.
In einer Ausgestaltung ist die Bedienplatte einstückig mit dem Pedalarm gefertigt, wo bei die Kippbarkeit durch Materialschwächung bewirkt ist. Dies vereinfacht die Ferti gung. In one embodiment, the control panel is made in one piece with the pedal arm, where the tiltability is caused by a weakening of the material. This simplifies production.
In einer alternativen Ausgestaltung ist die Bedienplatte separat von dem Pedalarm ge fertigt und mittels einer elastischen Platte an dem ersten Ende befestigt. Hierdurch ist der Widerstand gegen das Kippen einfach und genau festlegbar, was sich positiv auf die Bremssteuerung auswirkt. In einer weiteren Ausgestaltung umfasst der Positionssensor einen Hallsensor und einen Magneten. Hallsensoren sind vielfach und preiswert auf dem Markt verfügbar. In an alternative embodiment, the control panel is manufactured separately from the pedal arm and attached to the first end by means of an elastic plate. As a result, the resistance to tilting can be easily and precisely determined, which has a positive effect on the brake control. In a further embodiment, the position sensor comprises a Hall sensor and a magnet. Hall sensors are widely available and inexpensive on the market.
Alternativ ist z.B. ein induktiver Positionssensor einsetzbar. Alternatively, e.g. an inductive position sensor can be used.
In einer weiteren Ausgestaltung sind der Pedalarm und die Bedienplatte aus Kunst stoff gefertigt. So kann das Bremspedal z.B. aus preiswertem Material im Spritzguss gefertigt werden, was die Fertigung vereinfacht und die Kosten reduziert. In a further embodiment, the pedal arm and the control panel are made of plastic. For example, the brake pedal can be made of inexpensive material using injection molding, which simplifies production and reduces costs.
In einer weiteren Ausgestaltung ist die Platte aus Federstahl gefertigt. Hierbei ist der Widerstand gegen das Kippen besonders gut festlegbar. In a further embodiment, the plate is made of spring steel. The resistance to tilting can be determined particularly well here.
In einer weiteren Ausgestaltung ist ein Drehwinkelsensor zur Bestimmung eines Drehwinkels des Pedalarms angeordnet. Hierdurch wird die Bremssteuerung weiter verbessert. In a further embodiment, a rotation angle sensor is arranged for determining a rotation angle of the pedal arm. This further improves the brake control.
Anhand der beigefügten schematischen Zeichnung wird die Erfindung nachfolgend näher erläutert. Dabei zeigen: The invention is explained in more detail below with reference to the attached schematic drawing. Show:
Figur 1 einen Längsschnitt durch ein Bremspedal und Figure 1 shows a longitudinal section through a brake pedal and
Figur 2 eine Draufsicht auf das Bremspedal. Figure 2 is a plan view of the brake pedal.
Wie aus den Figuren ersichtlich umfasst ein Bremspedal 1 einen Pedalarm 2 und eine Bedienplatte 3. As can be seen from the figures, a brake pedal 1 comprises a pedal arm 2 and an operating panel 3.
Der Pedalarm 2 ist im Bereich seines ersten, bei in einem Kraftfahrzeug montiertem Zustand oberen Endes 2.1 gelenkig lagerbar. Hierfür ist in einem Bereich des ersten Endes 2.1 eine Durchgangsbohrung 4 eingelassen, in der ein Lagerbolzen positio nierbar ist. Eine Drehachse des Pedalarms 2 ist senkrecht zu einer Längsachse des Pedalarms 2 und parallel zu einer Bedienebene der Bedienplatte 3. Für eine Ermitt lung eines Drehwinkels des Pedalarms 2 ist ein Drehwinkelsensor angeordnet. An einem zweiten, dem ersten Ende 2.1 entgegengesetzten Ende 2.2 des Pedalarms 2 ist eine fingerartige Verlängerung 5 derart angeformt, dass zwischen gegenüber lie genden Flächen der Verlängerung 5 und der Bedienplatte 4 ein erster Spalt gebildet ist; dieser erste Spalt definiert einen lichten Abstand zwischen der Bedienplatte 3 und der Verlängerung 5. The pedal arm 2 can be articulated in the area of its first end 2.1, which is at the top when it is mounted in a motor vehicle. For this purpose, a through hole 4 is let into a region of the first end 2.1, in which a bearing pin can be positioned. An axis of rotation of the pedal arm 2 is perpendicular to a longitudinal axis of the pedal arm 2 and parallel to an operating plane of the control panel 3. For a determination of an angle of rotation of the pedal arm 2, a rotation angle sensor is arranged. At a second end 2.2 of the pedal arm 2 opposite the first end 2.1, a finger-like extension 5 is formed in such a way that a first gap is formed between the opposite lying surfaces of the extension 5 and the control panel 4; this first gap defines a clear distance between the control panel 3 and the extension 5.
In einem von dem zweiten Ende 2.2 entfernten Endbereich der Verlängerung 5 ist ein Hallsensor 6 als Positionssensor 6 befestigt. Der Hallsensor 6 wirkt mit einem Magne ten 7 zusammen, der jenem gegenüberliegend an der Bedienplatte3 befestigt ist. In an end region of the extension 5 remote from the second end 2.2, a Hall sensor 6 is attached as a position sensor 6. The Hall sensor 6 interacts with a magnet 7 which is attached to the control panel 3 opposite it.
Alternativ zu dem Hallsensor 6 und dem Magneten 7 ist ein anderer Positionssensor einsetzbar, der z.B. auf Induktivität oder Kapazität beruht. As an alternative to the Hall sensor 6 and the magnet 7, another position sensor can be used that is based on inductance or capacitance, for example.
Der Positionssensor 6 ist elektrisch mittels Kabel 9 mit einer Steuereinrichtung für eine Bremsanlage des Kraftfahrzeugs verbunden. The position sensor 6 is electrically connected by means of a cable 9 to a control device for a brake system of the motor vehicle.
Die Bedienplatte 3 ist an dem zweiten Ende 2.2. des Pedalarms 2 mittels einer Platte 8 befestigt. Die Platte 8 ist z.B. in einem Bereich des zweiten Endes 2.2 und und ei nem benachbarten Bereich der Bedienplatte 2 so eingegossen, dass zwischen dem zweiten Ende 2.2 und der Bedienplatte 3 ein zweiter Spalt gebildet ist. Hierdurch ist eine Kippbarkeit der Bedienplatte3 relativ zu den Pedalarm 2 und somit eine Verände rung einer Weite des ersten Spalts bei Einwirkung einer Kraft gewährleistet. Eine Ach se der Kippbewegung befindet sich zwischen dem ersten Ende 2.1 sowie der Bedien platte 3 und ist parallel zu dem Lagerbolzen. The control panel 3 is at the second end 2.2. of the pedal arm 2 is fastened by means of a plate 8. The plate 8 is, for example, cast in an area of the second end 2.2 and an adjacent area of the control panel 2 so that a second gap is formed between the second end 2.2 and the control panel 3. This ensures that the control panel 3 can be tilted relative to the pedal arm 2 and thus a change in the width of the first gap when a force is applied. An Ach se the tilting movement is located between the first end 2.1 and the control plate 3 and is parallel to the bearing pin.
Der Pedalarm 2 und die Bedienplatte 3 sind z.B. aus Kunststoff im Spritzguss gefer tigt. Die Platte 8, der Hallsensor 6 und der Magnet 7 sind vor dem Guss vorzugsweise in eine Spritzform eingelegt. Die Platte 8 ist z.B. aus Federstahl. The pedal arm 2 and the control panel 3 are, for example, made of plastic by injection molding. The plate 8, the Hall sensor 6 and the magnet 7 are preferably placed in an injection mold before casting. The plate 8 is made of spring steel, for example.
Alternativ sind der Pedalarm 2 und die Bedienplatte 5 aus Stahl gefertigt, wobei die Bedienplatte 3 einen rutschhemmenden Überzug aufweist. Alternatively, the pedal arm 2 and the control panel 5 are made of steel, the control panel 3 having an anti-slip coating.
Im Betrieb des Kraftfahrzeugs muss dieses gebremst werden. Hierfür tritt ein Fahrer auf die Bedienplatte 3, was jeweils ausgehend von einer Grundposition einerseits ein Verschwenken des gesamten Bremspedals 1 um den Lagerbolzen und andererseits ein Kippen der Bedienplatte 3 um die Achse der Kippbewegung bewirkt. Das Ver schwenken des Bremspedals 1 wird durch den Drehwinkelsensor registriert und als Signal an die Steuereinrichtung weitergeleitet. Durch das Kippen wird der erste Spalt, also der lichte Abstand zwischen der Verlängerung 5 und der Bedienplatte 3, verklei nert. Diese Verkleinerung wird durch den Positionssensor 6 bestimmt und durch das Kabel 9 als Signal an die Steuereinrichtung übermittelt, die die Signale auswertet und in entsprechende Steuerbefehle an die Bremsanlage ausgibt. When the motor vehicle is in operation, it must be braked. For this purpose, a driver steps on the control panel 3, which occurs on the one hand starting from a basic position Pivoting the entire brake pedal 1 around the bearing pin and, on the other hand, tilting the control panel 3 around the axis of the tilting movement. The United swing the brake pedal 1 is registered by the rotation angle sensor and forwarded as a signal to the control device. By tilting the first gap, so the clear distance between the extension 5 and the control panel 3, is reduced. This reduction in size is determined by the position sensor 6 and transmitted as a signal through the cable 9 to the control device, which evaluates the signals and outputs corresponding control commands to the brake system.
Das Treten auf die Bedienplatte 3 erfolgt gegen eine Kraft, die eine Betätigung eins herkömmlichen Bremspedals simuliert und vorzugsweise mit dem Weg ansteigt. Stepping on the control panel 3 takes place against a force which simulates an actuation of a conventional brake pedal and preferably increases with the travel.
Beim Loslassen des Bremspedals 1 gehen das Bremspedal 1 und die Bedienplatte 3 in ihre Ausgangspositionen zurück, was der Positionssensor 6 bestimmt und als zu geordnete Signale an die Steuereinrichtung übermittelt. Diese gibt Steuerbefehle zum Lösen der Bremsanlage aus. When the brake pedal 1 is released, the brake pedal 1 and the control panel 3 return to their starting positions, which the position sensor 6 determines and transmits to the control device as associated signals. This issues control commands to release the brake system.
