Abstract
Description
Einrichtung zum Regeln der Fahrgeschwindigkeit eines KraftfahrzeugsDevice for regulating the driving speed of a motor vehicle
Die Erfindung bezieht sich auf eine Einrichtung zum Regeln der Fahrge schwindigkeit eines Kraftfahrzeugs mit einem vom Fahrzeugführer betätigbaren Stellglied, insbesondere einem Gaspedal, und einem elektrischen Regler, dessen Sollwerteingang mit dem Ausgangssignal eines ersten, mit dem Stellglied gekuppelten elektrischen Stellungsgebers und dessen Istwerteingang mit dem Ausgangssignal eines zweiten elektrischen Stellung gebers beaufschlagt ist, der mit einem Stellorgan gekuppelt ist, das einerseits mit dem das Kraftstoff-Luft-Gemisch beeinflussenden Element, insbesondere der Drosselklappe, und andererseits Uber 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 vehicle speed of a motor vehicle with an actuator that can be actuated by the driver, in particular an accelerator pedal, and an electrical controller, whose setpoint input with the output signal of a first electrical one coupled to the actuator Position transmitter and its actual value input with the output signal of a second electrical Position sensor is applied, which is coupled to an 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).
Wie im Hauptpatent ausgeführt ist, hat eine solche Einrichtung im Vergleich zu den bekannten Einrichtungen, bei denen das Gaspedal über einen Bowdenzug oder über ein Gestänge mit der Drosselklappe im Motorraum verbunden ist, den Vorteil, daß aufgrund der elektrischen Verbindung von Stellglied bzw. Gaspedal und dem die Drosselklappe betätigenden Stellmotor die Montage der Einrichtung wesentlich leichter durchzuführen ist.As stated in the main patent, 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 the actuator or accelerator pedal and the Throttle valve actuating servomotor makes the assembly of the device much easier is to be carried out.
Darüber hinaus ergeben sich Vorteile hinsichtlich der auf das Gaspedal auszuübenden Stellkräfte sowie hinsichtlich der Anbringungsmöglichkeiten 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 mounting options of the accelerator pedal in the motor vehicle.
Bei der Erfindung nach dem Hauptpatent wird bei Betätigen der Bremse des Fahrzeugs oder der Fahrzeugkupplung die Kupplungseinrichtung zwischen dem Stellmotor und dem Stellorgan unwirksam geschaltet, das heißt die Kupplung trennt den Stellmotor vom Stellorgan, so daß die Drosselklappe ungehindert aufgrund der an ihr angreifenden Rückholfeder in ihre Rbhestellung zurückschwenken kann. Beim Zurückschwenken der Droselklappe wird durch diese auch das Stellorgan und der mit diesem in Verbindung stehende zweite Stellungsgeber in seine Ruhestellung zurijckbEwcgt.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 switched ineffective, that is the coupling separates the servomotor from the actuator so that the throttle valve is unimpeded due to the return spring acting on it can pivot back into its position. When the throttle flap is pivoted back, the actuator and the with this connected second position transmitter 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 anomales Betriebsverhalten des Motors ergibt. Zur Beseitigung dieses anomalen Betriebsverhaltens ist bereits vorgeschlagen worden, die Kupplungseinrichtung des Reglers bei Betätigen der Fahrzeugbremse oder der Fahrzeugkupplung nur kurzzeitig unwirksam zu schalten und danach durch Wiedereinschalten der Kupplung die eventuell nicht in ihre Ruhelage zurückverschwenkte Drosselklappe durch den Stellmotor zuruckzubewegen. Hierzu ist es erforderlich, daS der Stellmotor ein gewisses Mindestdrehmoment erzeugt, mit der die Drosselklappe in ihre Ausgangsstellung zurückbewegt werden kann. Ist die Vereisung zu stark oder ist das zwischen der Drosselklappe und dem Stellmotor vorhandene Gestänge verklemmt oder ist gar die Kupplungseinrichtung zwischen dem Stellmotor und dem Gestänge nicht in Ordnung, so ist eine Zurückführung der Drosselklappe in ihre Ausgangsstellung durch den Motor nicht möglich. Insbesondere wenn die Drosselklappe in ihrer Vollgasstellung oder in einer dieser Stelle benachbarten Stellung hängenbleibt, können sich gefährliche Uerkehrssituationen ergeben, die unter Umständen sogar zu einem VErkehrsunfall führen 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. To eliminate this abnormal operating behavior, it has already been proposed that the clutch device of the controller when the vehicle brake or the vehicle clutch is actuated to be switched ineffective only for a short time and then by switching on the clutch again the throttle valve, which may not be pivoted back into its rest position, by the Actuator to move back. For this it is necessary that the servomotor has a certain Minimum torque generated with which the throttle valve moves back to its starting position can be. Is the icing too strong or is it between the throttle valve and the servomotor existing linkage jammed or is even the coupling device between the servomotor and the linkage is not in order, it is a return the throttle valve cannot be returned to its starting position by the engine. In particular when the throttle valve is in its full throttle position or in one of these positions Stuck position, dangerous reversal situations can arise may even lead to a traffic accident.
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 erfindungsgemän dadurch gelöst, daß Mittel vorgesehen sind, die bei Abweichung des Ausgangssignals des zweiten Stellungsgebers von demjenigen des ersten Stellungsgebers um einen bestimmten vorgegebenen Betrag den Zündstromkreis des Kraftfahrzeugmotors unterbrechen.This object is achieved according to the invention in that means are provided are that when the output signal of the second position transmitter deviates from that of the first position transmitter by a certain predetermined amount the ignition circuit interrupt the motor vehicle engine.
Auf diese Weise ist sichergestellt, daß bei einem ttängenbleiben der Drosselklappe in einer Position ausserhalb ihrer Ruhestellung, der Zündstromkreis des Kraftfahrzeugmotors unterbrochen, das Antriebssystem des Kraftfahrzeugs also außer Betrieb gesetzt wird. Gefährliche Vcrkehrssituationen aufgrund einer hangengebliebenen Drosselklappe können dadurch nicht mehr auftreten.In this way it is ensured that if the Throttle valve in a position outside of its rest position, the ignition circuit the motor vehicle engine is interrupted, so the drive system of the motor vehicle is taken out of service. Dangerous traffic situations due to a stuck Throttle valves can no longer occur.
Als zweckmäßig hat es sich erwiesen, wenn die Mittel eine optische und/oder akustische Warnvorrichtung enthalten, die zeitlich vor der Unterbrechung des Zündstromkreises wirksam schaltbar sind. Auf diese Weise wird der Fahrer von der kurz darauf erfolgenden zwangsweisen Außerbetriebsetzung des Antriebssystems seines Kraftfahrzeugs unterrichtet und kann mithin noch entsprechende verkehrsgerechte Maßnahmen, wie Heranfahren an die rechte Stranenseite, treffen. Aus dem gleichen Grunde hat es sich als zweckmäßig erwiesen, einen manuell bedienbaren Schalter zum Unwirksamschalten der Mittel vorzusehen.It has proven to be useful if the means are optical and / or contain audible warning devices in time prior to the interruption of the ignition circuit can be effectively switched. In this way, the driver of the forced shutdown of the drive system shortly afterwards of his motor vehicle and can therefore still use the appropriate traffic-friendly Take measures such as approaching the right side of the beach. For the same Basically, it has proven to be useful to use a manually operated switch for Provision for ineffective switching of the funds.
Dadurch besteht die Möglichkeit, nach einer vorgenommenen Notabschaltung des Antriebssystems dieses erneut in Betrieb setzen zu können, um beispielsweise das Fahrzeug aus einer Gefahrenzone zu bewegen.This makes it possible to switch off after an emergency shutdown of the drive system to be able to put it into operation again, for example to move the vehicle out of a danger zone.
GemäB einer vorteilhaften Ausführungsform umfassen die Mittel einen komparator, dem einerseits das Ausgangssignal des zweiten Stellung gebers und andererseits das des ersten Stellungsgebers zugeführt ist und einen diesem nachgeschalteten Schwellwertschalter, der direkt oder indirekt, beispielsweise über ein Relais, den Zündstromkreis schaltet.According to an advantageous embodiment, the means comprise one comparator, on the one hand the output signal of the second position transmitter and on the other hand that is fed to the first position transmitter and a threshold value switch connected downstream of this, which switches the ignition circuit directly or indirectly, for example via a relay.
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 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 2 gibt.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, an actuator 6 and a interposed electromagnetic clutch 7 is constructed. The regulator 1 also contains a position transmitter 8, which is connected to the actuator 6 and a voltage proportional to the respective position of the position transmitter 8 to one input of the comparator 2 there.
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.At the other input of the comparator 2, for example from a Series connection of two resistors is built, which at their free ends with the signals to be compared are applied and their interconnected The ends of the comparator output form the position transmitter 9, which is considered to be variable Resistance is formed and coupled to the accelerator pedal 10 of the motor vehicle.
Sowohl der Stellungsgeber 9 als auch der Stellungs3eber 8 sind an die beiden Eingange eines Komparators 11 angeschlossen, dessen Ausgang mit einem Schwellwertschalter 12 in Verbindung steht. Der Ausgang des Schwellwertschalters 12 ist einerseits an eine akustische Warneinrichtung 13 und andererseits über eine Zeitverzägerungsschaltung 14 an eine Schaltstufe 15 angeschlossen, deren Schaltelement im Zündstromkreis liegt.Both the position transmitter 9 and the position transmitter 8 are on the two inputs of a comparator 11 connected, the output of which with a Threshold switch 12 is connected. The output of the threshold switch 12 is on the one hand to an acoustic warning device 13 and on the other hand via a Time delay circuit 14 connected to a switching stage 15, the switching element is in the ignition circuit.
Zur Erlauterung der Wirkungsweise der Einrichtung sei davon ausgegangen, daß das Gaspedal 10 aus seiner Ruhelage verschwenkt ist und mithin auch die Drosselklappe 16 um einen entsprechenden Winkel verschwenkt ist. Die an den Eingängen des Vergleichers 2 und des Vergleichers 11 erscheinenden Signale sind mithin gleich und das Ausgangs~ signal des Vergleichers 11 ist derart, daß der Schwellwertschalter 12 nicht geschaltet wird. Entfernt der Fanrer nunmehr seinen FuB vom Gaspedal 10, so geht dies in seine Ruhestellung zurück. Die gleichzeitige Rückstellung der Drosselklappe 16 sei nun dadurch verhindert, daß das Ansaugsystem vereist ist. Die Folge ist, daß sich das vom Stellungsgeber 8 abgegebene Signal nicht wandert und mithin am Vergleicher 11 zwischen dem vom Stellungsgeber 8 kommenden Signal und demjenigen, das vom Stellungsgeber 9 kommt, eine solche Signaldifferenz entsteht, daß der Uergleicher 11 den Schwellwertschalter 12 aufsteuert. Die akustische Warneinrichtung 13 wird in Betrieb gesetzt und nach einer durch die Zeitverzögerungsstufe 14 gegebenen Zeitverzögerung von einigen Sekunden wird über die Stufe 15 der Zündstromkreis des Motors ausgeschaltet. Ist zwischen der Stufe 14 und der Stufe 15 ein Schalter 17 vorhanden, so kann über diesen normalerweise geschlossenen Schalter die Stufe 15 unwirksam geschaltet und mithin das Antriebssystem des Kraftfahrzeugs erneut in Betrieb gesetzt werden.To explain how the device works, it is assumed that that the accelerator pedal 10 is pivoted out of its rest position and therefore also the throttle valve 16 is pivoted through a corresponding angle. The ones at the inputs of the comparator 2 and the comparator 11 appearing signals are therefore the same and the output ~ signal of the comparator 11 is such that the threshold switch 12 is not switched will. The fan now removes his foot from the accelerator pedal 10, so this goes back to its rest position. The simultaneous resetting of the throttle valve 16 is now prevented by the fact that the intake system is iced up. The result is, that the signal emitted by the position transmitter 8 does not migrate and therefore on Comparator 11 between the signal coming from the position transmitter 8 and the one that comes from the position transmitter 9, such a signal difference arises that the matched 11 controls the threshold switch 12. The acoustic warning device 13 is put into operation and after a time delay given by the time delay stage 14 After a few seconds the ignition circuit of the engine is switched off via stage 15. If a switch 17 is present between stage 14 and stage 15, then over this normally closed switch, the stage 15 switched ineffective and consequently the drive system of the motor vehicle can be put into operation again.
