Einrichtung zum Regeln der Fahrgeschwindigkeit eines Kraftfahrzeugs Die Erfindung bezieht sich auf eine Einrichtung zum Regeln der Fahrgeschwindigkeit eines Kraftfahrzeugs mit einem vom Fahrzeugführer bet3tigbaren Stellglied, insbesondere einem Gaspedal, und einem elektrischen Regler, dessen Sollwerteingang mit dem Ausgangssignal eines ersten, mit dem Stellglied gekuppelten elektrischen Stellungsgeber und dessen Istwerteingang mit dem Ausgangssignal eines zweiten elektrischen Stellungsgebers beaufschlagt ist, der mit einem 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 Wirkverb,ndung steht, insbesondere nach Patent ....., (Patentanmeldung P 27 14 113.5-21).Device for regulating the driving speed of a motor vehicle The invention relates to a device for regulating the driving speed of a motor vehicle with an actuator that can be operated by the driver, in particular an accelerator pedal, and an electrical controller, whose setpoint 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 an actuator that is on the one hand with the 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).
Wie im Hauptpatent ausgeführt ist, hat eine solche Einrichtung im Vergleich zu bekannten Einrichtungen, bei denen das Gaspedal uber einen Bowdenzug oder ein Gestänge mit der Drosselklappe im Motorraum verbunden ist, den Vorteil, daß aufgrund der elektrischen Verbindung von Gaspedal und den die Drosselklappe verstellenden Stellmotor die Montage der Einrichtung außerst einfach ist und sich insbesondere eine leichtgängige Verstellbarkeit des Gaspedals ergibt, die in weiten Grenzen an die jeweiligen Erfordernisse angepaBt werden kann. Zudem lassen sich die Neigung.des Gaspedals, der Abstand zum Fahrersitz und schlieBlich der Anbringungsort bei der Einrichtung nach dem Hauptpatent ebenfalls in weiten Grenzen an die unterschiedlichsten Erfordernisse anpassen.As stated in the main patent, such a device in Compared to known devices in which the accelerator pedal is via a Bowden cable or a linkage is connected to the throttle valve in the engine compartment, the advantage that due to the electrical connection of the accelerator pedal and the throttle valve adjusting servomotor, the assembly of the device is extremely simple and easy in particular, a smooth adjustability of the accelerator pedal results in wide Limits can be adapted to the respective requirements. In addition, the inclination of the accelerator pedal, the distance to the driver's seat and finally the location with the establishment according to the main patent also within wide limits to the most varied Adjust requirements.
Insbesondere die Möglichkeit, den Anbringungsort des Stellungsgebers, der sowohl ein Gaspedal als auch ein Handgriff oder dergleichen sein kann, nahezu beliebig wählen zu können, macht diese Einrichtung besonders geeignet für die Anwendung in Fahrzeugen für Behinderte.In particular, the possibility of determining the location of the position transmitter, the can be both an accelerator pedal and a handle or the like, almost any being able to choose makes this device particularly suitable for use in Vehicles for the disabled.
Bei der Einrichtung nach dem Hauptpatent wird bei Betätigen der Bremse des Fahrzeugs oder der Fahrzeugkupplung beispielsweise bei einem Schaltvorgang die Kupplungseinrichtung zwischen dem Stellmotor und dem Stellorgan unwirksam geschaltet, das heißt, die Kupplung trennt den Stellmotor vom Stellorgan, und durch die federbelastete Drosselklappe wird das Stellorgan und der mit ihm in Verbindung stehende Stellungsgeber in seine Ruhestellung verschwenkt.In the device according to the main patent, when the brake is operated of the vehicle or the vehicle clutch, for example during a shift Coupling device switched ineffective between the servomotor and the final control element, that is, the clutch separates the servomotor from the actuator, and through the spring-loaded one The throttle valve becomes the final control element and the position transmitter connected to it pivoted into its rest position.
Es hat sich nun gezeigt, daß insbesondere bei Schaltvorgängen, bei denen das Gaspedal bekanntlich rasch zurUckgenommen und anschließend sofort die Fahrzeugkupplung betätigt wird, aber auch bei Bremsvorgängen der Regler einem solchen Vorgang nur so stark zeitverzögert folgen kann, daß kurzzeitig eine un2rwünschte Drehzahlüberhöhung des Motors auftritt.It has now been shown that in particular when switching operations who, as is well known, quickly took back the accelerator and then immediately the Vehicle clutch is actuated, but also during braking the controller such Process can only follow with such a long delay that an undesired The engine speed increases.
Dieser Nachtell soll durch die Erfindung überwunden werden Es ist daher Aufgabe der Erfindung, die Einrichtung nach dem }iauptpatent so zu verbessern, daß eine Drehzahlüberhöhung bei einem Schaitvorgang oder auch bei einem Bremsvorgang nicht stattfindet.This disadvantage is to be overcome by the invention It is Hence the object of the invention to improve the device according to the main patent in such a way that that an increase in speed during a shifting process or also during a braking process not taking place.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß vor Betätigung der Fahrzeugkupplung undisoer der Fahrzeugbremse die Kupplungseinrichtung im Sinne eines Trennens angesteuert ist.According to the invention, this object is achieved in that prior to actuation the vehicle clutch undisoer the vehicle brake the clutch device in the sense a disconnection is controlled.
Gemaß einer Ausführungsform der Erfindung kann dies dadurch geschehen, daB die Rückstellgeschsindigkeit des Stellgliedes erfaßt und bei Überschreiten einer bestimmten vorgegebenen uckstellgeschwindigkeit die Kupplungseinrichtung im Sinne eines Trennens angesteuert ist.According to one embodiment of the invention, this can be done by that the restoring speed of the actuator is detected and when a certain predetermined reset speed the Coupling device is controlled in the sense of a separation.
Hierbei wird also das zur Ansteuerung der Kupplungseinrichtung benötigte Signal von der Rnckstellgeschwindigkeit des Gaspedals abgeleitet, die ja bei einem Schaltvorgang wie auch bei einem plötzlich erforderlich werdenden Bremsvorgang besonders hoch ist und somit als Kriterium für einen solchen Schalt- bzw. Bremsvorgang herangezogen werden kann. Die Erfassung und Auswertung der RUckstellgeschwindigkeit kann in vorteilhafter Weise dadurch erfolgen, daß der Ausgang des mit dem Stellglied gekuppelten Stellungsgebers Uber ein Differenzierglied mit einem Schwellwertschalter verbunden ist, der den Steuerstromkreis der Kupplungseinrichtung ansteuert. Es wird hierbei also die Ånderungsgeschwindigkeit des vom Stellungsgeber kommenden Signals erfaßt. Bei einer bestimmten Größe der Signaländerung spricht der Schwellwertschalter an und steuert die Kupplungseinrichtung im Sinne eines Trennens an.This is what is required to control the clutch device Signal derived from the reset speed of the accelerator pedal, which is true for a Shifting process as well as a braking process that suddenly becomes necessary is high and is therefore used as a criterion for such a switching or braking process can be. The detection and evaluation of the reset speed can be advantageous Wise done in that the output of the position transmitter coupled to the actuator A differentiator is connected to a threshold switch that controls the Controls the control circuit of the clutch device. So here it becomes the rate of change of the signal coming from the position transmitter. With a certain size of the The threshold switch responds to a signal change and controls the coupling device in the sense of a separation.
Gemäß einer anderen Ausführungsform der Erfindung ist die Kupplungseinrichtung im Sinne eines Trennens angesteuert, wenn eine bestimmte vorgegebene Differenz zwischen Sollwert und Istwert erreicht ist.According to another embodiment of the invention, the coupling device controlled in the sense of a disconnection when a certain predetermined difference between Setpoint and actual value are reached.
Hierbei wird die Ublicherweise vorhandene Trägheit des Reglers als Kriterium für das nachfolgende Betätigen der Fahrzeugkupplung oder der Fahrzeugbremse benutzt. In einer sich darauf beziehenden vorteilhaften Realisierungsform ist ein vom Ausgangssignal des Reglers gespeister Schwellwertschalter vorhanden, der den Steuerstromkreis der Kupplungseinrichtung ansteuert.Here, the usually existing inertia of the controller as Criterion for the subsequent actuation of the vehicle clutch or the vehicle brake used. In an advantageous implementation form relating to this, a There is a threshold value switch fed by the output signal of the controller, which controls the Controls the control circuit of the clutch device.
Die Erfindung sei anhand der Zeichnung, die Ausfuhrungsbeispiele enthält, näher erläutert. Es zeigen Figur 1 ein Blockschaltbild einer Einrichtung,bei der das Steuersignal für die Kupplungseinrichtung von der Rückstellgeschwindigkeit des Stellgliedes gewonnen wird und Figur 2 ein Blockschaltbild einer Einrichtung, bei der das Steuersignal für die Kupplungseinrichtung aus der Ist-Soll-Wert-Differenz gewonnen wird.The invention is based on the drawing, which contains exemplary embodiments, explained in more detail. FIG. 1 shows a block diagram of a device in which the control signal for the clutch device from the return speed of the Actuator is obtained and Figure 2 is a block diagram of a device at the control signal for the clutch device from the actual / target value difference is won.
Die Einrichtung nach Figur 1 enthält einen elektrischen Regler 1, der im wesentlichen aus einem Ueroleicher 2, einem diesem nachgeschalteten Verstärker 3 und einer Stelivorrichtung 4 besteht, die aus einem elektrischen Servomotor 5, einem 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 Vergleichers 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 Widerstand ausgebildet und mit dem Gaspedal 10 des Kraftfahrzeugs gekuppelt ist. Der Ausgang des Stellungsgebers 9 ist des weiteren an ein Differenzierglied 16 angeschlossen, dem ein Schwellwertschalter 17 nachgeschaltet ist. Der Ausgang des Schwellwertschalters 17 steuert einen Transistor 18, in dessen Emitter-Kollektor-Strecke die Erregerwicklung 19 der elektromagnetischen Kupplung 7 lIegt.The device according to Figure 1 contains an electrical controller 1, which essentially consists of a Ueroleicher 2, a downstream amplifier 3 and a positioning device 4, which consists of an electric servo motor 5, an actuator 6 and an interposed electromagnetic clutch 7 is constructed. The controller 1 also contains a position transmitter 8, which with the actuator 6 is connected and one of the respective position of the position transmitter 8 outputs proportional voltage to one input of the comparator. At the other Input of the comparator 2, for example, from a series connection of two Resistors are built up at their free ends with the signals to be compared are acted upon and their interconnected ends the comparator output form, is the position transmitter 9, which is designed as a variable resistor and is coupled to the accelerator pedal 10 of the motor vehicle. The output of the position transmitter 9 is also connected to a differentiating element 16, which is a threshold switch 17 is connected downstream. The output of the threshold switch 17 controls a transistor 18, in whose emitter-collector path the excitation winding 19 of the electromagnetic Coupling 7 is in place.
Zur Erläuterung der Strkungsweise der Einrichtung sei davon ausgegangen, daß das Gaspedal 10 um einen bestimmten Betrag aus seiner Ruhelage verschwenkt ist und mithin der Stellungsgeber 9 ein diesem Verschwenkwinkel entsprechendes Signal an den lergleicher2 des Reglers 1 abgibt Demzufolge ist auch die Drnsselklappe 15 verschwenkt und zwar um einen dem s uenkuflnkel des Gaspedais entsprechenden Serto Der rotor dreht daher mit einer bestimmtenDrehzahl Erfolgt nun aufgrund eines Schaltvorgangs eine Rückstellung des Gaspedals 10 in seine Ruhestellung, so ändert sich das vom Stellungsgeber 9 abgegebene Ausgangssignal mit der bei einer solchen Gaspedalruckstellung typischen Änderungsgeschwindigkeit. Dieses sich ändernde Signal wird in dem Differenzierglied 16 differenziert und danach dem Schwellwertschalter 17 zugefUhrt, der den Transistor 18, der normalerweise in DurchlaBrichtung geschaltet ist, in seine Sperrrichtung steuert. Die Folge ist, daß die Kupplung 7 im Sinne eines Trennens betätigt wird. Diese Betätigung erfolgt vor einer Betätigung der Kupplung 7 Uber den Kupplungsschalter 2fl bzw. den Bremsschalter 21.To explain the strength of the facility, it is assumed that that the accelerator pedal 10 is pivoted by a certain amount from its rest position and consequently the position transmitter 9 sends a signal corresponding to this pivot angle to the equalizer 2 of the controller 1 pivoted around a serto corresponding to the lower angle of the accelerator pedal The rotor therefore rotates at a certain speed. This is now due to a switching process a return of the accelerator pedal 10 to its rest position, it changes from Position transmitter 9 output signal with that of such a Accelerator pedal position typical rate of change. This changing signal is differentiated in the differentiator 16 and then the threshold switch 17 fed to the transistor 18, which is normally switched in the forward direction is, controls in its blocking direction. The result is that the clutch 7 in the sense a disconnection is operated. This actuation takes place before actuation of the Clutch 7 via the clutch switch 2fl or the brake switch 21.
Die in Figur 2 dargestellte Einrichtung besitzt bis auf die Ansteuerung des Transistors 18 den gleichen Aufbau wie die Einrichtung nach Figur 1. Wie ersichtlich, ist an den Ausgang des Vergleichers 2 ein Schwellwertschalter 22 angeschlossen, dessen Ausgangssignal den Transistor 18 steuert. Die Ansteuerung des Transistors 18 erfolgt, wenn zwischen dem Sollwert und dem Istwert, die beide dem Vergleicher 2 zugeführt sind, eine Differenz auftritt, die einen bestimmten vorgegebenen Wert, der durch den Schwellwertschalter 22 festlegbar ist, überschritten wird.The device shown in Figure 2 has except for the control of transistor 18 has the same structure as the device according to FIG. 1. As can be seen, a threshold switch 22 is connected to the output of the comparator 2, the output signal of which controls the transistor 18. The control of the transistor 18 takes place when between the setpoint and the actual value, both the comparator 2 are supplied, a difference occurs which has a certain predetermined value, which can be set by the threshold switch 22 is exceeded.
