Description

Kombiniertes FahrpedalCombined accelerator pedal

Beschreibung.Description.

1. Allgemein:1 General:

Mit dem „Kombinierten Fahrpedal" wird bei einem PKW oder LKW sowohl die Antiebskraft als auch die Bremskraft geregelt, Der Vorteil liegt darin, daß der Bedienungsfuß nicht mehr vom Pedal abgehoben werden muß. Die sogenannte Reaktionszeit ,als die Zeit,die vom Erkennen eines plötzlichen Hindernisses bis zum Einsetzen der Bremswirkung vergeht, wird kurzer, weil mit dem Fuß kein Pedalwechsel mehr erfolgt, sondern nur ein „Absatzkick".The "combined accelerator pedal" is used to regulate both the driving force and the braking force in a car or truck. The advantage is that the operating foot no longer has to be lifted off the pedal. The so-called reaction time, i.e. the time that passes from the detection of a sudden obstacle to the onset of the braking effect, is shorter because the foot no longer changes pedal, but only a "heel kick".

Der effektive Zeitgewinn ist individuell verschieden. Die Gefahr des Abrutschern vom Bremspedal beim schnellen Pedalwechsel wird vermieden.The effective time saved varies from person to person. The risk of slipping off the brake pedal when changing pedals quickly is avoided.

2. Funktion:2. Function:

Ein Fußpedal ( Zeichnung 1, Pos. 1) ist im Fußraum eines Fahrzeuges so angeordnet und ca. mittig gelagert, daß von einer Mittelrast des Pedals aus die Bewegung der Pedalspitze nach vorn die Antriebskraft regelt und die Rückwärtsbewegung mit dem Absatz die Bremsen betätigt. (Zeichnung 1.). Dies wird erfindungsgemäß so gelöst, daß die Bremskraft abhängig vom Fußdruck von einem durch elektrische Signale angesteuerten Bremskraftverstärker verstärkt wird. Dazu ist auf der Achse des Kolbens des Hauptbremszylinders eine „Druckdose" mit piezoelektrischen Gebern angeordnet. (Zeichnung 1, Pos. 2.). Mit der Rückwärtsbewegung und dem Absatzdruck wird die Kraft über die Druckdose auf den Kolben des Hauptbremszylinders geleitet. Die piezoelektrischen Geber in der Druckdose verändern druckproportional eine elektrische Primärspannung, die nach einer Verstärkung den Bremskraftverstärker steuert. Mit zunehmendem Pedaldruck wird auch die Bremskraftverstärkung größer. Da die piezoelektrischen Geber praktisch nur auf Druck reagieren, ist dieBremskraft- bzw. die Bremskraftverstärkung nur vom Pedaldruck abhängig, was eine sehr sensible Bremskraftdosierung erlaubt. Bei Wegnahme des Pedaldruckes führt eine Rückholfeder die Achse des Bremskolbens mit der Druckdose und dem Stößel in die Ausgangslage zurück und das' Pedal in die Mittellage.A foot pedal (Drawing 1, Item 1) is arranged in the footwell of a vehicle and mounted approximately centrally so that the movement of the pedal tip forwards from a central notch of the pedal regulates the driving force and the backward movement with the heel activates the brakes. (Drawing 1.) This is solved according to the invention in such a way that the braking force is increased depending on the foot pressure by a brake booster controlled by electrical signals. For this purpose, a "pressure cell" with piezoelectric sensors is arranged on the axis of the piston of the master brake cylinder. (Drawing 1, item 2.). With the backward movement and the heel pressure, the force is transferred via the pressure cell to the piston of the master brake cylinder. The piezoelectric sensors in the pressure cell change an electrical primary voltage proportional to the pressure, which controls the brake booster after amplification. As the pedal pressure increases, the brake force amplification also increases. Since the piezoelectric sensors practically only react to pressure, the brake force or the brake force amplification is only dependent on the pedal pressure, which allows very sensitive brake force dosing. When the pedal pressure is removed, a return spring returns the axis of the brake piston with the pressure cell and the tappet to the starting position and the pedal to the middle position.

Bei der Vorwärtsbewegung des Pedals wird ausgehend von der Mittellage nur die Antriebskraft in bekannterweise geregelt; die Bremse wird nicht betätigt.When the pedal is moved forwards, starting from the middle position, only the drive force is regulated in the usual way; the brake is not applied.

3. Schlußbemerkung:3. Concluding remark:

Mit dem"Kombinierten Fahrpedal" wird die Fahrsicherheit durch Verkürzung der Reaktionszeit erhöht. „Fehltritte" und „Abrutschen" werden verhindert. Der Bedienungskomfort wird durch die Einfußbedienung erhöht. The "combined accelerator pedal" increases driving safety by shortening reaction times. "Missteps" and "slipping" are prevented. Operating comfort is increased by one-foot operation.
