Abstract

The speed control for the vehicle uses a servo motor linked to the carburettor by a servo clutch and operated by a remote throttle control. The system can be automatic speed control or a speed control for an invalid driven vehicle. The clutch is momentarily disengaged when the main clutch or brakes are applied. The system prevents the engine racing if the main clutch is applied, or the engine stalling if the brakes are rapidly applied. It enables the throttle setting to return to idling.

Description

Einrichtung zum Regeln der Fahrqeschwindiqkeit eines KraftfahrzeunsDevice for regulating the speed of a motor vehicle

Die Erfindung bezieht sich auf eine Einrichtung zum Regeln der Fahrgeschwindigkeit eines Kraftfahrzeugs mit einem vom Fahrzeugführer betätigbaren Stellglied, insbesondere einem Gaspedal, und einem elektrischen Regler, dessen Sulluierteingang mit dem Ausgangssignal eines ersten, mit dem Stellglied gekuppelten elektrischen Stellungsgebers und dessen Istwcrteingang mit dem Ausgangssignal eines zweiten elektrischen Stellungsgebers beaufschlagt ist, der mit einem starren Stellorgan gekuppelt ist, das einerseits mit dem das Kraftstoff-Luft-Gemisch beeinflussenden Element, insbesondere der Drosselklappe, und andererseits über eine elektrisch betätigbare Kupplungseinrichtung mit einem Stellmotor in Wirkverbindung steht, insbesondere nach Patent .... (Patentanmeldung P 27 14 113.5-21).The invention relates to a device for regulating the driving speed of a motor vehicle with an actuator that can be actuated by the vehicle driver, in particular an accelerator pedal, and an electrical controller, whose leveling input with the output signal a first electrical position transmitter coupled to the actuator and its Actual value input with the output signal of a second electrical position transmitter is acted upon, which is coupled to a rigid actuator that on the one hand with the element influencing the fuel-air mixture, in particular the throttle valve, and on the other hand via an electrically operated coupling device with a Servomotor is in operative connection, in particular according to patent .... (patent application P 27 14 113.5-21).

zSie im Hauptpatent ausgeführt ist, hat eine solche Einrichtung im Vergleich zu den bekannten Einrichtungen, bei denen das Gaspedal über ein Bowdenzug oder über ein Gestänge mit der Drosselklappe im Motorraum verbunden ist, den Vorteil, daß aufgrund der elektrischen Verbindung von Stellglicil bzw. Glspedal und dem die Drosselklappe betätigen den Stellmotor die Montage der Einrichtung wesentlich leichter ist.zIt is set out in the main patent, has such a device in Compared to the known devices in which the accelerator pedal is via a Bowden cable or is connected to the throttle valve in the engine compartment via a linkage, the advantage that due to the electrical connection of Stellglicil or Glspedal and the the Throttle valve actuate the servomotor making the assembly of the device much easier is.

Darüber hinaus ergeben sich Vorteile hinsichtlich der auf das Gaspedal auszuübenden Stellkräfte sowie hinsichtlich der Anbringungsmuglichkeiten des Gaspedals im Kraftfahrzeug.In addition, there are advantages in terms of the accelerator pedal actuating forces to be exerted as well as with regard to the possibilities of attaching the accelerator pedal in the motor vehicle.

Bei der Erfindung nach dem Hauptpatent wird bei Betätigen der Bremse des Fahrzeugs oder der Fahrzeugkupplung die Kupplungsein richtung zwischen dem Stellmotor und dem Stellorgan unwirksam geschaltet, d.h. die Kupplung trennt den Stellmotor vom Stellorgan, so daß die Drosselklappe ungehindert aufgrund der an ihr angreifenden Rückstellfeder in ihre Ruhestellung zuruckschwenken kann.In the invention according to the main patent, when the brake is operated of the vehicle or the vehicle coupling, the coupling device between the servomotor and the actuator are switched ineffective, i.e. the clutch disconnects the actuator from the actuator, so that the throttle valve is unimpeded due to the attack on it Return spring can pivot back into its rest position.

Beim Zurückschwenken der Drosselklappe wird durch diese auch das Stellorgan und der mit diesem in Verbindung stehende Stellungsgeber in seine Ruhestellung zurückbewegt.When the throttle valve is swiveled back, it also acts as the final control element and the position transmitter associated with this is moved back into its rest position.

Unter Umständen kann es nun geschehen, daß beispielsweise bei einer Vereisung des Ansaugsystems die Drosselklappe durch die an ihr angreifende Feder nicht aus ihrer verschwenkten Stellung in ihre Ruhestellung zurückgezogen werden kann, so daß sich ein unerwünschtes anormales Betriebsverhalten des Motors ergeben kann. Ein derartiger anormaler Betriebszustand kann zwar auch bei den bekannten Einrichtungen auftreten, bei denen das Gaspedal uber einen Bowdenzug oder über ein Gestänge mit der Drosselklappe verbunden ist, Jedoch besteht dort die Möglichkeit, durch Ziehen des Gaspedals die Drosselklappe wieder in ihre Ruhestellung zuruckbewegen zu können.Under certain circumstances it can now happen that, for example, with a Icing of the intake system, the throttle valve due to the spring acting on it not be withdrawn from their pivoted position into their rest position may result in undesirable abnormal performance of the engine can. Such an abnormal operating condition can also occur in the known Facilities occur in which the accelerator pedal is via a Bowden cable or via a Linkage is connected to the throttle valve, but there is the possibility of by pulling the accelerator pedal, move the throttle valve back to its rest position to be able to.

Dieser Nachteil soll durch die Erfindung überwunden werden. Es ist daher Aufgabe der Erfindung, die Einrichtung nach dem Hauptpatent so zu verbessern, daß ein derartiges anormales Betriebsverhalten nicht mehr auftreten kann.This disadvantage is intended to be overcome by the invention. It is therefore the object of the invention to improve the device according to the main patent so that that such abnormal performance can no longer occur.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Mittel vorgeschen sind, die bei Betätigen der Fahrzeugbremse, der Fahrzeugkupplung und/oder eines anderen ein Nullstellsignal erzeugenden Elements die Kupplungseinrichtung nur kurzzeitig unwirksam schalten.This object is achieved according to the invention in that means are provided are that when the vehicle brake, the vehicle clutch and / or a other element generating a zero setting signal, the clutch device only briefly switch to ineffective.

Durch diese Maßnahme wird erreicht, daß bei nichterfolgtem Rücklauf der Drosselklappe während des kurzzeitigen Unwirksamschaltens diese danach beim Wiederwirksamschalten der Kupplungseinrichtung zwangsweise durch den Stellmotor in ihre Ruhelage zurückbewegt wird. Wie Versuche gezeigt haben, genügt es, die Kupplungseinrichtung für etwa 0,2 Sekunden unwirksam zu schalten, d.h. die Verbindung zwischen Stellmotor und Stellorgan zu trennen. Während dieser Zeit ist ein Zurückkippen der Drosselklappe in ihre Ausgangsstellung ohne weiteres möglich. Selbstverständlich kann die Zeitdauer, während der die Kupplungseinrichtung unwirksam geschaltet wird, auch länger sein, jedoch besteht dann die Gefahr, daß sich insbesondere bei Schaltvorgängen störende Wirkungen im Regel ablauf ergeben.This measure ensures that if the return does not take place the throttle valve during the short-term ineffective switching this thereafter forcibly by the servomotor when the coupling device is switched back on is moved back to its rest position. As tests have shown, it is sufficient to use the coupling device to be deactivated for about 0.2 seconds, i.e. the connection between the servomotor and actuator to separate. During this time there is a tilting back of the throttle valve in their starting position easily possible. Of course, the length of time during which the coupling device is switched ineffective, also be longer, however, there is then the risk that disruptive switching operations, in particular, will occur Results in the normal course of action.

Gemäß einer AusführJJngsform der Erfindung ist ein monostabiler Multivibrator vorgesehen, der bei Betätigen der Fahrzeugbremse, der Fahrzeugkupplung und/oder eines anderen ein Nullstellsignal erzeugenden Elements in seinen quasistabilen Zustand gesteuert ist und während dieses Zustandes die Kupplungseinrichtung ausschaltet. Die Ansteuerung des monostabilen Multivibrators kann unmittelbar von dem von der Fahrzeugbremse, der Fahrzeugkupplung und/oder dem Element aus erfolgen.According to one embodiment of the invention is a monostable multivibrator provided that when the vehicle brake, the vehicle clutch and / or another element generating a zeroing signal into its quasi-stable state is controlled and switches off the clutch device during this state. The monostable multivibrator can be controlled directly by the Vehicle brake, the vehicle clutch and / or the element made.

Die Kippzeit wird so bemessen, daß die zwangsläufige Rückführung der Drosselklappe in ihre Ruhestellung erst dann erfolgt, wenn die normale Abregelzeit abgelaufen ist; die zwangsläufige Rückführung greift in diesem Fall also nicht in den normalen Abregelvorgang ein.The tilting time is measured in such a way that the inevitable return of the Throttle valve in its rest position only takes place when the normal down regulation time has expired; the inevitable return does not apply in this case the normal curtailment process.

Die Erfindung sei anhand der Zeichnung, die ein Ausführungsbeispiel enthält, näher erläutert.The invention is based on the drawing, which shows an embodiment contains, explained in more detail.

Die Einrichtung enthält einen elektrischen Regler 1, der im wesentlichen aus einem Vergleicher 2, einem diesem nachgeschalteten Verstärker 3 und einer Stellvorrichtung 4 besteht, die aus einem elektrischen Servomotor 5, einem starren Stellorgan 6 und einer dazwischengeschalteten elektromagnetischen Kupplung 7 aufgebaut ist. Der Regler 1 enthält des weiteren einen Stellungsgeber 8, der mit dem Stellorgan 6 verbunden ist und eine der jeweiligen Position des Stellungsgebers 8 proportionale Spannung an den einen Eingang des Verglei chers 2 abgibt. Am anderen Eingang des Vergleichers 2, der beispielsweise aus einer Reihenschaltung zweier Widerstände aufgebaut ist, die an ihren freien Enden mit den zu vergleichenden Signalen beaufschlagt sind und deren miteinander verbundene Enden den Vergleicherausgang bilden, liegt der Stellungsgeber 9, der als veränderlicher Widesstand ausgebildet und mit dem Gaspedal 10 des Kraftfahrzeugs gekuppelt ist.The device contains an electrical controller 1, which is essentially from a comparator 2, an amplifier 3 connected downstream of this and an adjusting device 4 consists of an electric servo motor 5, a rigid actuator 6 and an interposed electromagnetic clutch 7 is constructed. The regulator 1 also contains a position transmitter 8, which is connected to the actuator 6th is connected and one of the respective position of the position transmitter 8 proportional Voltage to one input of the comparator 2 outputs. At the other entrance of the Comparator 2, which for example consists of a series connection of two resistors is constructed, which is acted upon at its free ends with the signals to be compared and their interconnected ends form the comparator output the position transmitter 9, which is designed as a variable Widesstand and with the Accelerator pedal 10 of the motor vehicle is coupled.

Zur Erläuterung der Wirkungsweise der Einrichtung sei davon ausgegangen, daß sich das Gaspedal 10 in einer Stellung außerhalb seiner Ruhelage befinde und mithin der Motor mit einer oberhalb der Leerlaufdrehzahl liegenden Drehzahl läuft. Die Drosselklappe 15 befindet sich in einer dieser Drehzahl entsprechenden Stellung. Die Erregerspule 16 ist mit Strom beaufschlagt und die Kupplung in ihrer eingerückten Stellung, in der sie das Stellorgan 6 mit dem Motor 5 verbindet.To explain how the device works, it is assumed that that the accelerator pedal 10 is in a position outside of its rest position and consequently the engine is running at a speed above the idling speed. The throttle valve 15 is in a position corresponding to this speed. The excitation coil 16 is energized and the clutch is engaged Position in which it connects the actuator 6 to the motor 5.

Sobald die Bremse oder die Kupplung des Fahrzeugs betätigt und mithin der der Bremse zugeordnete Schalter 17 bzw. der der Kupplung zugeordnete Schalter 18 geschlossen wird, wird der in dem Erregerstrom kreis der Kupplung liegende Transistor 19 gesperrt und die Kupplung im Sinne einer Trennung betätigt, da der monostabile Multivibrator 20 in seinen quasistabilen Zustand gesteuert und der Transistor 21 in Sperrichtung geschaltet wird. Nach Zurückkippen des monostabilen Multivibrators 20 wird der Transistor 21 wieder leitend und steuert dadurch den Transistor 19 in seinen leitenden Zustand. Die Erregerspule 16 wird wieder mit Strom beaufschlagt, und die Kupplung verbindet wieder das Stellorgan 6 mit dem Motor 5, der die zwangsläufige Rückführung der Drosselklappe 15 in ihre Ruhestellung vornimmt, falls sie zuvor nicht zurückgekippt ist.As soon as the brake or the clutch of the vehicle is actuated and therefore the switch 17 assigned to the brake or the switch assigned to the clutch 18 is closed, the transistor lying in the excitation circuit of the clutch is 19 locked and actuated the clutch in the sense of a separation, since the monostable Multivibrator 20 is controlled in its quasi-stable state and transistor 21 is switched in the blocking direction. After tilting back the monostable multivibrator 20, the transistor 21 becomes conductive again and thereby controls the transistor 19 in its conducting state. The excitation coil 16 is energized again, and the coupling again connects the actuator 6 with the motor 5, which is the inevitable Returns the throttle valve 15 to its rest position, if they did before has not tilted back.
