Description
Vorrichtung zum Abstellen des Motors eines Device for stopping the engine of a
Kraftfahrzeuges mit Automatik-Getriebe Bei Kraftfahrzeugen mit Automatik-Getriebe besteht zwecks Benzineinsparung und Umweltschutz ein Bedarf an einer selbsttätigen Abstellung des Motors beim Anhalten vor Verkehrsampeln und in Staus. Motor vehicle with automatic transmission In motor vehicles with automatic transmission there is a need for an automatic in order to save gasoline and protect the environment Engine shutdown when stopping at traffic lights and in traffic jams.
Es sind bereits Anordnungen für diesen Zweck vorgeschlagen, die jedoch darunter leiden, daß beim Wiederanlassen des Motors eine zuverlässige Absicherung gegen vorzeitiges Vorwärtsrollen fehlt.Arrangements have already been proposed for this purpose, however suffer from the fact that when the engine is restarted, a reliable protection against premature rolling forward is absent.
Gemäß vorliegender Erfindung zeichnet sich eine Anordnung für selbsttätiges Abstellen des Motors eines Kraftfahrzeuges beim Anhalten vor Verkehrsampeln und dergleichen in erster Linie dadurch aus, daß zum Wiederanlassen des beim Anhalten abgestellten Motors die Betätigung des Bremspedals als Impulsgabe für eine elektronische Anlaßvorrichtung benutzt wird. Die Erfindung wird im folgenden anhand eines Beispiels gemäß beiliegender Zeichnung näher beschrieben.According to the present invention, an arrangement for automatic Switching off the engine of a motor vehicle when stopping at traffic lights and The like primarily in that to restart the when stopping turned off the engine, the operation of the brake pedal as an impulse for an electronic Starting device is used. The invention is illustrated below by means of an example described in more detail according to the accompanying drawing.
Der Thyristor 50 ist anodenseitig dem Bremslichtschalter 60 angeschlossen und dessen Gate kann über einen Trigger 51 einer mit einer Zenerdiode 52 konstant gehaltenen Spannung zugeführt werden. Der Trigger 51 läßt jedoch nur dann Strom durch, wenn die auf seiner Steuerelektrode anliegende Spannung einen bestimmten Wert unterschreitet. Triggerelemente dieser Art sind z.B.The thyristor 50 is connected to the brake light switch 60 on the anode side and its gate can be constant with a Zener diode 52 via a trigger 51 maintained voltage are supplied. The trigger 51, however, only allows current when the voltage on its control electrode reaches a certain level Value falls below. Trigger elements of this type are e.g.
unter der Bezeichnung MUS 887 bekannt und handelsüblich.known and commercially available under the name MUS 887.
Die Spannung auf der Steuerelektrode wird in Abhängigkeit der Motordrehzahl dadurch erzeugt, daß von der Zündspule 22 Impulse über einen Kondensator 57 und zwei Dioden 53, 54, einem RC-Kreis 55, 56 zugeführt werden.The voltage on the control electrode depends on the engine speed generated by the fact that the ignition coil 22 Pulses through a capacitor 57 and two diodes 53, 54, an RC circuit 55, 56 are fed.
Die Vorrichtung arbeitet wie folgt: Beim Anhalten vor einer roten Ampel oder dergl. wird das Bremspedal betätigt, um das Fahrzeug zum Stillstand zu bringen. Dabei wird auch dem Thyristor 50 anodenseitig Spannung zugeführt. Solange die Spannung auf der Steuerelektrode des Triggers 51 einen kritischen Wert übersteigt, läßt jedoch der Thyristor 50 keinen Strom durch. Erst wenn die Motordrehzahl genügend abgesunken ist und aufgrund dessen der Kondensator 56 sich durch den Regelwiderstand 55 über einen gewissen Zeitraum entsprechend entladen hat, schaltet der Trigger 51 den Thyristor 50 ein. Der Strom durch den Thyristor lädt den Kondensator 37 auf und bewirkt durch Umpolung das Abschalten deì Thyristors 13. Dies bedeutet, daß die Motorzündung 22 abgestellt wird. Wenn der Fahrer wieder den Motor anlassen will, läßt er für einen Moment das Bremspedal so weit locker, daß der Bremslichtschalter 60 abschaltet und drückt danach wieder auf das Pedal.The device works as follows: When stopping in front of a red At traffic lights or the like, the brake pedal is operated to bring the vehicle to a standstill bring. In this case, voltage is also supplied to the thyristor 50 on the anode side. So long the voltage on the control electrode of trigger 51 exceeds a critical value, however, the thyristor 50 does not pass any current. Only when the engine speed is sufficient Has dropped and due to which the capacitor 56 is through the variable resistor 55 has discharged accordingly over a certain period of time, the trigger switches 51 the thyristor 50. The current through the thyristor charges the capacitor 37 and causes the thyristor 13 to be switched off by reversing the polarity. This means that the engine ignition 22 is turned off. If the driver wants to start the engine again, he lets the brake pedal so loose for a moment that the brake light switch 60 switches off and then presses the pedal again.
Das Wiederschließen des Bremslichtkontakts verursacht einen Stromimpuls über den Kondensator 18 und schaltet damit den Thyristor 12 ein. Demzufolge läuft der Anlasser 23 an und bleibt solange eingeschaltet, bis über den Thyristor 13 die Spannung der Lichtmaschine 25 den Thyristor einschaltet. Die Einschalturig des Thyristors bewirkt über den Kondensator 15 durch Umpolung ein Abschalten des Thyristors 12. Der Anlasser 23 wird dadurch abgeschaltet und die Zündanlage wird weiterhin über den Thyristor 13 mit Strom versorgt. Die Funktion des Zündschlosses 21 bleibt von diesen Einrichtungen unberührt.Closing the brake light contact again causes a current pulse via the capacitor 18 and thus switches the thyristor 12 on. As a result, runs the starter 23 and remains switched on until the thyristor 13 the Voltage of the alternator 25 turns on the thyristor. The switching on of the thyristor causes the thyristor 12 to be switched off via the capacitor 15 by reversing the polarity. The starter 23 is thereby switched off and the ignition system continues to be over the thyristor 13 is supplied with power. The function of the ignition lock 21 remains these facilities unaffected.
In einer Variante dieser Vorrichtung kann die Spannung zum Einschalten des Thyristors 13 an Stelle von der Lichtmaschine auch von dem RC-Kreis 55, 56 genommen werden, um bei der aufgrund des Anlassens des Motors steigenden Spannung den Thyristor 13 einschalten zu lassen.In a variant of this device, the voltage can be switched on of the thyristor 13 is also taken from the RC circuit 55, 56 instead of the alternator to control the thyristor when the voltage rises due to the starting of the engine 13 switched on.
Die großen Vorteile einer Vorrichtung gemäß dieser Erfindung sind folgende: Sowohl das Abstellen als auch das Wiederanlassen des Motors erfolgt ohne jegliches zusätzliche Betätigungselement. Das Abstellen geschieht zwangsläufig, aber mit einigen Sekunden Verzögerung in Abhängigkeit des Abbremsens des Fahrzeuges sowie der auf Leerlauf absinkenden Motordrehzahl. Das Automatik-Getriebe bleibt bei diesem Vorgang unverändert in seiner Vorwärtsstellung. Beim Wiederanlassen des Motors kann durch Impulsgabe mit dem Bremspedal das Cetriebe ohne jede Gefahr in Vorwärtsstellung bleiben, da das Fahrzeug bei anspringendem Motor zwangsläufig gebremst ist.The great advantages of a device according to this invention are the following: The engine is both switched off and restarted without any additional actuator. The parking is inevitable, but with a delay of a few seconds depending on the braking of the vehicle as well as the engine speed falling to idle. The automatic transmission remains in this process unchanged in its forward position. When restarting the The motor can enter the gearbox without any danger by giving impulses with the brake pedal Stay forward position as the vehicle inevitably brakes when the engine starts is.
Im Rahmen der Erfindung liegen selbstverständlich auch alle Arten Kombinationen, bei denen das Abstellen des Motors durch einen separaten Schalter erfolgt.Of course, all types are also within the scope of the invention Combinations in which the engine can be switched off using a separate switch he follows.
