The output signal of the differentiating element feeds a limiter amplifier (9), the output signal of which in turn intervenes in the adjustment of an actuator (5) influencing the fuel-air mixture of the engine. With this device there is a periodic adjustment of the actuator which compensates for disturbing changes in speed, while the actuator is not additionally noticeably affected in the event of an arbitrary change in position of the actuator by the accelerator pedal.

Description

Die Erfindung betrifft eine Einrichtung zur Herabsetzung von Fahrzeuglängsdynamik-Instabilitäten nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for reducing vehicle longitudinal dynamics instabilities according to the preamble of claim 1.

Die Fahrzeuglängsdynamik-Instabilitäten äußern sich darin, daß beim willkürlichen Beschleunigen durch Betätigung des Gaspedals außerdem unerwünschte periodische Beschleunigungs- änderungen hervorgerufen werden. Die Beschleunigungen werden auf den Fahrer übertragen, der damit eine unerwünschte Stellungsänderung des Gaspedals hervorruft. Das gesamte Schwingungssystem, welches das Fahrzeug mit Elastizitäten im Antriebsstrang, zu beschleunigende Massen und Trägheitsmomente sowie die Leistungsabgabe des Verbrennungsmotors entsprechend dem Betriebspunkt in der Drehmoment/Drehzahlkennlinie und weitere Faktoren umfaßt, kann dynamisch instabil sein. Damit kann es zu einer aufklingenden Schwingung kommen, bei der im Extremfall fast der gesamte Gaspedalstellweg unwillkürlich durchlaufen wird (Bonanza-Effekt).The vehicle longitudinal dynamics instabilities are manifested in the fact that, during arbitrary acceleration, actuation of the accelerator pedal also causes undesired periodic changes in acceleration. The accelerations are transmitted to the driver, who thus causes an undesired change in the position of the accelerator pedal. The entire vibration system, which includes the vehicle with elasticities in the drive train, masses to be accelerated and moments of inertia as well as the power output of the internal combustion engine according to the operating point in the torque / speed characteristic and other factors, can be dynamically unstable. This can lead to an oscillation in which, in extreme cases, almost the entire accelerator pedal travel is involuntary (Bonanza effect).

Um dieser unerwünschten Erscheinung abzuhelfen, die insbesondere bei Verbrennungsmotoren mit steiler Drehmoment/ Drehzahlkennlinie auftritt, hat man bereits versucht, dieIn order to remedy this undesirable phenomenon, which occurs particularly in internal combustion engines with a steep torque / speed characteristic, attempts have already been made to

Längs-Schwingungen des Fahrzeug/Fahrersystems dadurch zu dämpfen, daß das Gaspedal über ein Verzögerungsglied mit dem Steller in Verbindung steht, welcher das Kraftstoff-Luftgemisch des Ver_brennungsmotors steuert. Das Verzögerungsglied wurde insbesondere durch einen hydraulischen Dämpfer verwirklicht. - Nachteilig bei dieser Dämpfungsmaßnahme ist, daß auch die willkürlich durch den Fahrer ausgelösten Verstellungen des Gaspedals ebenfalls nur verzögert in entsprechende Positionen des Stellers umgesetzt werden. Durch diesen Dämpfer in der Verbindung zwischen Gaspedal und Steller tritt somit eine unerwünschte Verzögerung im Ansprechverhalten des Verbrennungsmotors ein. Hinzu kommen Abstimmungsschwierigkeiten des Dämpfers, da die in der Verbindung zwischen Gaspedal und Motor zu dämpfende periodische Schwingung von dem Fahrzeugtyp und - bei gegebenen Fahrzeugtyp - von dem eingelegten Gang abhängt. Grundsätzlich ist darüber hinaus diese bekannte Methode zur scheinbaren Verbesserung der Fahrzeuglängsstabilität wirkungslos, wenn die störenden Anregungen der Schwingungen nicht über das Gaspedal eingeleitet werden, sondern an anderen Stellen, beispielsweise durch Schalt- oder Kupplungsvorgänge oder Fahrbahn-Unebenheiten.To dampen longitudinal vibrations of the vehicle / driver system in that the accelerator pedal is connected via a delay element to the actuator which controls the fuel-air mixture of the internal combustion engine. The delay element was realized in particular by means of a hydraulic damper. - A disadvantage of this damping measure is that the accelerator pedal adjustments which are arbitrarily triggered by the driver are also only implemented with a delay in corresponding positions of the actuator. This damper in the connection between the accelerator pedal and the actuator thus causes an undesirable delay in the response behavior of the internal combustion engine. In addition, there are coordination difficulties of the damper, since the periodic vibration to be damped in the connection between the accelerator pedal and the engine depends on the vehicle type and - for a given vehicle type - on the gear selected. In principle, this known method for apparently improving the longitudinal stability of the vehicle is also ineffective if the disturbing excitations of the vibrations are not initiated via the accelerator pedal, but at other points, for example through shifting or clutching processes or bumps on the road.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung zu schaffen, welche die schädlichen Auswirkungen der Fahrzeuglängsdynamik-Instabilitäten unabhängig von der Angriffsstelle der Störeinflüsse wirksam vermindert, deren Parameter unkritisch einstellbar sind und welche das Ansprech. verhalten des Verbrennungsmotors auf willkürliche Gaspedalbetätigung nicht spürbar verschlechtert.The invention is therefore based on the object of providing a device which effectively reduces the harmful effects of the longitudinal dynamics instabilities of the vehicle independently of the point of attack of the interference, the parameters of which can be set uncritically and the response. behavior of the internal combustion engine on arbitrary accelerator pedal actuation not noticeably worsened.

Diese Aufgabe wird durch die in dem kennzeichnenden Teil des Anspruchs 1 angegebene Erfindung gelöst.This object is achieved by the invention specified in the characterizing part of claim 1.

Die Lösung beruht auf dem Prinzip, daß aus der Motordrehzahl ein geeignetes Signal abgeleitet wird, welches zu dem im Sinne einer Regelung auf minimalen Ruck des Fahrzeugs, Steller des Kraftstoff-LuftgemischesYrückgeführt wird. Hierzu werden die Drehzahländerungen des Motors erfaßt und wenn sie als störend, d.h. nicht durch den Fahrer willkürlich ausgelöst erkannt werden, in gegenläufige Stellungsänderungen des Stellers umgesetzt. Willkürliche Gaspedaländerungen durch den Fahrer werden jedoch durch die Einrichtung nicht dämpfend beeinflußt. Im einzelnen wird diese Dämpfung der Fahrzeuglängsdynamik-Instabilitäten mit elektrischen Mitteln durchgeführt, indem von der Motordrehzahl emeelektrische Spannung abgeleitet wird, welche anschließend differenziert und über einen Begrenzer-Verstärker übertragen wird.The solution is based on the principle that a suitable signal is derived from the engine speed, which signal is fed back to the positioner of the fuel-air mixture Y in the sense of regulation to a minimal jerk of the vehicle. For this purpose, the speed changes of the motor are recorded and if they are disturbing, i.e. not recognized by the driver as being triggered arbitrarily, implemented in opposite position changes of the actuator. However, arbitrary accelerator pedal changes by the driver are not dampened by the device. In particular, this damping of the vehicle longitudinal dynamics instabilities is carried out by electrical means, by deriving electrical voltage from the engine speed, which is then differentiated and transmitted via a limiter amplifier.

Nach Anspruch 2 wird der Eingriff dieses Begrenzer-Verstärkers besonders zweckmäßig auf ca. 50 % des Arbeitsbereichs der Verstellung des Stellers begrenzt. Damit ist eine sichere Kompensation von Störschwingungen gewährleistet, andererseits wirkt sich die Kompansation nicht nachteilig bei willkürlichen Beschleunigungs- und Verzögerungsvorgängen durch den Fahrer aus.According to claim 2, the intervention of this limiter amplifier is expediently limited to approximately 50% of the working range of the adjustment of the actuator. This ensures reliable compensation of interference vibrations, on the other hand the compensation does not have a disadvantageous effect on the driver's arbitrary acceleration and deceleration processes.

Besonders zweckmäßig wird diese Einrichtung mit einer üblichen Einrichtung zur elektrischen Verstellung des Stellers durch das Gaspedal kombiniert. Dabei erfolgt die Einkopplung des von dem Begrenzer-Verstärker abgegebenen Signals zweckmäßig am Ausgang der Einrichtung zur elektrischen Verstellung des Stellers durch das Gaspedal (E-Gas). - Bei dieser Kombination ist der Zusatzaufwand für die Einrichtung zum Herabsetzen der störenden Auswirkungen von Fahrzeuglängsdynamik-Instabilitäten besonders niedrig, da die Verstellung des Stellers mit elektromechanischen Mitteln erfolgt.This device is particularly advantageously combined with a conventional device for electrical adjustment of the actuator by the accelerator pedal. The signal emitted by the limiter amplifier is expediently coupled in at the output of the device for electrical adjustment of the actuator by the accelerator pedal (E-gas). With this combination, the additional effort for the device for reducing the disruptive effects of longitudinal vehicle dynamics instabilities is particularly low, since the actuator is adjusted by means of electromechanical means.

Die Erfindung wird im folgenden anhand einer Zeichnung mit einer Figur erläutert, in der ein Signalflußbild der Einrichtung in Verbindung mit einer E-Gaseinrichtung dargestellt ist:

  • In Fig. 1 ist ein Gaspedal (Fahrpedal) mit 1 bezeichnet, dessen Stellung über einen elektrischen Stellungsgeber 2 in ein elektrisches Stellungssignal umgewandelt wird. Dieses Signal wird mit einem Verstärker 3 verstärkt und in eine entsprechende Position eines elektromechanischen Stellers 4 umgewandelt, welcher das Kraftstoff-Luftgemisch eines Verbrennungsmotors 5 bestimmt.
The invention is explained below with reference to a drawing with a figure, in which a signal flow diagram of the device is shown in connection with an E-gas device:
  • In Fig. 1, an accelerator pedal (accelerator pedal) is designated 1, the position of which is converted into an electrical position signal via an electrical position transmitter 2. This signal is amplified with an amplifier 3 and converted into a corresponding position of an electromechanical actuator 4, which determines the fuel-air mixture of an internal combustion engine 5.

Mit dieser herkömmlichen E-Gas Einrichtung ist folgende Einrichtung zur Herabsetzung von Fahrzeuglängsdynamik-Instabilitäten gekoppelt:

  • Mit einem drehbaren Element des Motors steht ein Drehzahlsensor 6 in Verbindung, der ein elektrisches Drehzahlsignal entsprechend der Motordrehzahl liefert. Dieses Drehzahlsignal wird in einem Drehzahl-Spannungswandler in eine proportionale Spannung umgesetzt. Diese Spannung wird in einem Differenzierglied 8, welches durch eine übliche Widerstandskondensatorkombination realisiert sein kann, differenziert und einem Begrenzer-Verstärker 9 zugeführt. Wie mit der in dem Begrenzer-Verstärker-Block angedeuteten Kennlinie 10 dargestellt ist, verstärkt der Verstärker annähernd linear, solange seine Ausgangsspannung einen vorgegebenen Spannungsbereich nicht überschreitet. Über diesen Bereich hinaus verstärkt der Verstärker aber nicht mehr, sondern seine Ausgangsspannung wird konstant auf einem maximalen Wert gehalten. Diese Begrenzerschaltung kann in üblicher Weise mit einer Zener-Diode realisiert werden.
This conventional e-gas device is coupled with the following device for reducing vehicle longitudinal dynamics instabilities:
  • A speed sensor 6 is connected to a rotatable element of the motor and supplies an electrical speed signal corresponding to the motor speed. This speed signal is converted into a proportional voltage in a speed-voltage converter. This voltage is differentiated in a differentiating element 8, which can be realized by a conventional resistance capacitor combination, and fed to a limiter amplifier 9. As is shown with the characteristic curve 10 indicated in the limiter-amplifier block, the amplifier amplifies approximately linearly as long as its output voltage does not exceed a predetermined voltage range. The amplifier no longer amplifies beyond this range, but its output voltage is kept constant at a maximum value. This limiter circuit can be implemented in the usual way with a Zener diode.

Das Ausgangssignal des Begrenzer-Verstärkers wird an einer Koppelstelle 11 in den Signalflußweg der E-Gaseinrichtung eingekoppelt.The output signal of the limiter amplifier is coupled into the signal flow path of the E-gas device at a coupling point 11.

Mit dieser Einrichtung werden periodische Schwingungen, die auf Fahrzeuglängsdynamik-Instabilitäten zurückzuführen sind, wie es sich gezeigt hat praktisch vollständig ausgeregelt, da jede Drehzahländerung des Motors eine gegenläufige Änderung der Stellerposition sofort hervorruft, so daß das Kraftstoff-Luftgemisch im kompensierenden Sinne beeinflußt wird. - Bei Betätigung des Gaspedals 1 hingegen, die eine gewünschte Änderung der Motordrehzahl durch Beeinflussung des Kraftstoff-Luftgemischs über den Steller hervorrufen soll wirkt der Begrenzer-Verstärker 9 begrenzend, so daß kein die Motordrehzahl kompensierendes Signal über die Koppelstelle 11 in den Steller 4 eingespeist wird. Der Fahrer merkt daher praktisch nicht, daß er mit einer Einrichtung zur Herabsetzung der Fahrzeuglängsdynamik-Instabilitäten fährt.With this device are periodic oscillations which are due to F ahrzeuglängsdynamik instabilities as shown has practically completely eliminated, since any change in speed of the engine causes an opposing change in the actuator position immediately, so that the fuel-air mixture is influenced in compensating sense. - When the accelerator pedal 1 is actuated, on the other hand, which is intended to cause a desired change in the engine speed by influencing the fuel-air mixture via the actuator, the limiter amplifier 9 has a limiting effect, so that no signal compensating the engine speed is fed into the actuator 4 via the coupling point 11 . The driver therefore hardly notices that he is driving with a device for reducing the vehicle longitudinal dynamics instabilities.

Diese Einrichtung hat sich als besonders vorteilhaft in Verbindung mit Dieselmotoren herausgestellt, die wegen ihrer weichen Aufhängung in dem Fahrzeug und ihrer Charakteristik Fahrzeuglängsdynamik-Instabilitäten verursachen.This device has proven to be particularly advantageous in connection with diesel engines which, due to their soft suspension in the vehicle and their characteristics, cause longitudinal dynamics instabilities in the vehicle.
