Description
Die
Erfindung betrifft ein Verfahren zum Steuern eines Automatikgetriebes,
wie es in der
Die
Bei den im Stand der Technik bekannten Getrieben ist von Nachteil, dass diese in besonderen Belastungssituationen nicht oder zu einem ungünstigen Zeitpunkt schalten.at the known in the art transmissions is disadvantageous that these in special stress situations not or at an unfavorable Switch time.
Es ist Aufgabe der Erfindung, ein insofern verbessertes Getriebe bereitzustellen.It The object of the invention is to provide a transmission improved in this respect.
Diese Aufgabe wird gemäß der Erfindung durch den Gegenstand der unabhängigen Patentansprüche gelöst. Vorteilhafte Weiter bildungen ergeben sich aus den jeweiligen abhängigen Ansprüchen.These Task is carried out according to the invention the subject of the independent claims solved. Advantageous further developments emerge from the respective dependent claims.
Die Erfindung geht von dem Grundgedanken aus, dass eine Hochschaltung in den nächsthöheren Gang dann angefordert wird, wenn in diesem nächsthöheren Gang die Beschleunigung mindestens genauso groß ist bzw. sein wird wie im aktuellen Gang. Anders als im Stand der Technik wird dabei nicht abgewartet, ob ein bestimmter in einer Schaltkennlinie abgelegter Schaltpunkt erreicht ist oder nicht, beispielsweise mit einer vorgegebenen Mindestbeschleunigung. Vielmehr berechnet sich das Getriebesteuergerät ausgehend vom aktuellen Gang und der aktuellen Motordrehzahl bzw. der aktuellen Geschwindigkeit des Kraftfahrzeugs die Zielmotordrehzahl bzw. die Zielgeschwindigkeit des Kraftfahrzeugs im nächst höheren Gang, Um die Beschleunigung im nächsthöheren Gang zu berechnen, ist die Kenntnis des Motordrehmoments bei Zielmotordrehzahl notwendig.The The invention is based on the idea that an upshift in the next higher gear is then requested, if in this next higher gear, the acceleration at least as big or will be like in the current gear. Unlike in the prior art is not waited whether a certain stored in a switching characteristic Switching point is reached or not, for example, with a predetermined Minimum acceleration. Instead, the gearbox control unit calculates starting from the current gear and the current engine speed or the current Speed of the motor vehicle, the target engine speed or the Target speed of the motor vehicle in the next higher gear, To the acceleration in the next higher gear is the knowledge of engine torque at target engine speed necessary.
Hierzu kann die Zielmotordrehzahl dem Motorsteuergerät übermittelt werden und dafür das Motormoment, welches auch zum aktuellen Fahrpedalwert des Kraftfahrzeugs passt, abgefragt werden. Dieses Motormoment wird dann vom Motorsteuergerät zum Getriebesteuergerät zurück übergeben und dort verwendet, um eine Entscheidung über ein Heraufschalten zu treffen oder nicht.For this the target engine speed can be transmitted to the engine control unit and the engine torque, which also matches the current accelerator pedal value of the motor vehicle, be queried. This engine torque is then transferred back from the engine control unit to the gearbox control unit and used there to make a decision about an upshift or not.
Abweichend davon kann in der Getriebesteuerung auch ein komplettes Motormomentenkennfeld abgelegt sein, da es insbesondere von Fahrpedalwert und von der Drehzahl des Motors abhängt. In einem Normalfall, in dem der Motor in unbelastetem Betrieb arbeitet, bei dem keine Reduktion der Leistung vorliegt, wird dieses Motormomentenkennfeld bestimmt. Das von der Motorsteuerung aktuell übermittelte Drehmoment wird permanent mit diesem abgelegten Wert verglichen und damit ein Korrekturfaktoren-Kennfeld ermittelt. Aus den Eingangsparametern "Zielmotordrehzahl" und "Pedalweg" kann aus dem abgelegten Motormomentenkennfeld und dem ermittelten Korrekturfaktor das Motormoment im neuen Gang bei Zielmotordrehzahl ermittelt werden.deviant of which, in the transmission control, a complete engine torque map be stored, since it in particular of accelerator pedal value and by the Speed of the engine depends. In a normal case where the engine is operating in unloaded operation, where there is no reduction in power, this engine torque map becomes certainly. The torque currently transmitted by the engine control becomes permanently compared with this stored value and thus a correction factor map determined. From the input parameters "target engine speed" and "pedal travel" can from the filed engine torque map and the determined correction factor, the engine torque in the new gear be determined at target engine speed.
Mit der Erfindung kann besonders einfach auf partielle Drehmomenteneinbußen bzw. – Reduktionen reagiert werden. Anders als bei einem Schaltpunkt, der fest vorgegeben ist, wird die Getriebesteuerung erweitert. Dadurch ist es nicht mehr notwendig, dass das Getriebe in einem niedrigeren Gang läuft, obwohl im nächsthöheren Gang noch genügend Zugkraft vorhanden wäre, um zumindest die momentane Bewegung aufrecht zu erhalten. Dadurch lässt sich die Motordrehzahl senken und der Verbrauch an Kraftstoff verringert sich.With The invention can be particularly easy on partial torque losses or - reductions be reacted. Unlike a switching point, which is fixed is, the transmission control is extended. It is not more necessary that the transmission runs in a lower gear, though in the next higher gear still enough Traction would be present to at least maintain the current movement. Thereby can the Lower engine speed and reduce fuel consumption yourself.
Die Getriebesteuerung errechnet sich ständig aus dem aktuellen Motormoment eine Soll-Beschleunigung. Diese Soll-Beschleunigung wird mit der tatsächlichen Beschleunigung verglichen und in Abhängigkeit der Differenz werden andere Schaltkennlinien z. B. für Bergauf- bzw. Bergabfahrt gewählt.The Transmission control is constantly calculated from the current engine torque a target acceleration. This target acceleration is compared with the actual Acceleration compared and depending on the difference other switching characteristics z. For example Uphill or downhill selected.
Die Festlegung dieser Schaltkennlinien geschieht in Abhängigkeit des vom Motor zur Verfügung gestellten Drehmoments als Funktion von Fahrpedal und Motordrehzahl.The Definition of these switching characteristics is dependent of the engine provided Torque as a function of accelerator pedal and engine speed.
Häufig wird in Folge äußerer Einflüsse (extreme Höhe, extreme klimatische Verhältnisse wie große Hitze, Verschleiß des Motors, Belastung mit Ladung) das Motormoment deutlich reduziert. Diese Reduzierung kann das Maß übersteigen, welches für die im Stand der Technik vorhandene Gangauswahl zugrunde gelegt wurde. Es kommt mit der Erfindung nicht mehr vor, dass die Gangauswahl des Automatikgetriebes nicht mehr zur Motormomentencharakteristik passt. Wenn an einer Steigung ein Kraftfahrzeug aufgrund der deutlichen Motormomentenreduzierung nicht mehr eine Geschwindigkeit erreicht, bei welcher normalerweise ein Gangwechsel durchgeführt würde, wird trotzdem ein Gangwechsel durchgeführt, denn im höheren Gang ist noch ausreichend Zugkraft vorhanden, um das Fahrzeug mit zumindest gleich bleibender Geschwindigkeit zu bewegen.Frequently becomes as a result of external influences (extreme Height, extreme climatic conditions How big Heat, wear of Motor, load with load) significantly reduces the engine torque. This reduction can exceed the measure which for the in the prior art existing gear selection was based. It is no longer possible with the invention that the gear selection of the automatic transmission no longer to the engine torque characteristic fits. If on a slope a motor vehicle due to the clear Engine torque reduction no longer reaches a speed which would normally be a gear change is performed nevertheless a gear change carried out, because in the higher gear is still sufficient traction available to the vehicle with at least the same to stay at a constant speed.
Die Erfindung wirkt sich dann besonders vorteilhaft aus, wenn der Motor sein Drehmoment nicht gleichmäßig im gesamten Kennfeld reduziert, sondern partiell besonders im oberen Drehzahlverlauf oberhalb des Momentenmaximums. Dies tritt typischerweise bei einem Dieselmotor auf, wenn Rauchbegrenzungsmaßnahmen oder Laderschutzfunktionen eines Turboladers aktiv werden.The Invention then has a particularly advantageous effect when the engine its torque is not uniform throughout Map reduced, but partially especially in the upper speed curve above the maximum torque. This typically occurs with a diesel engine on when smoke control measures or charger protection functions of a turbocharger become active.
Die Erfindung wird auch in einem Computerprogramm zum Ausführen des Verfahrens zum Betrieb eines Getriebes eines Kraftfahrzeuges verwirklicht. Das Computerprogramm enthält dabei Programmanweisungen, die eine Steuerungseinrichtung veranlassen, ein solches Verfahren in einer vorstehend beschriebenen Ausführungsform auszuführen. Dabei werden insbesondere die Verfahrensschritte beginnend mit dem Bestimmen einer Ist-Beschleunigung des Fahrzeugs, anschließendem Bestimmen einer Fahrgeschwindigkeit des Fahrzeugs und darauffolgendem Vorherbestimmen, ob bei der momentanen Fahrgeschwindigkeit in einem nächsthöheren Gang des Getriebes eine Beschleunigung möglich ist, die mindestens gleich groß ist, wie die Ist-Beschleunigung durchgeführt, so dass ein Schalten des Getriebes um einen Gang erfolgt, wenn diese Bedingung erfüllt ist.The Invention is also used in a computer program for executing the Implemented method for operating a transmission of a motor vehicle. The computer program contains while program instructions that cause a controller, such a method in an embodiment described above perform. there In particular, the method steps beginning with the determination an actual acceleration of the vehicle, then Determining a travel speed of the vehicle and subsequent Predict whether at the current driving speed in one next higher gear the transmission an acceleration is possible, at least the same is great like the actual acceleration carried out, so that a gear shift takes place around a gear, if this conditions met is.
Die Erfindung betrifft außerdem ein Computerprogramm, dass auf einem Speichermedium, insbesondere in einem Halbleiterspeicher oder in einem Direkt-Zugriffsspeicher enthalten ist, übertragen wird. Die Erfindung betrifft ferner auch ein Trägermedium, insbesondere einen Datenträger, wie beispielsweise eine Diskette, ein Zip-Laufwerk, einen Streamer eine CD oder eine DVD, auf denen ein vorstehend beschriebenes Computerprogramm abgelegt ist. Ferner betrifft die Erfindung ein Steuergerät, auf dem ein solches Computerprogramm gespeichert ist.The Invention also relates a computer program that runs on a storage medium, in particular in a semiconductor memory or in a direct access memory contained, transferred becomes. The invention also relates to a carrier medium, in particular a disk, such as a floppy disk, a Zip drive, a streamer a CD or a DVD on which a computer program described above is stored. Furthermore, the invention relates to a control device on which such a computer program is stored.
Die Erfindung ist in der Figur anhand eines Ausführungsbeispiels veranschaulicht.The Invention is illustrated in the figure with reference to an embodiment.
In
dem Diagramm in
Im Normalfall bewegt sich das Kraftfahrzeug in unbelastetem Zustand gemäß der Beschleunigungslinie a1. Etwa bei einer Geschwindigkeit von 40 km/h schaltet das automatische Getriebe in den zweiten Gang und das Fahrzeug bewegt sich entlang einer Beschleunigungslinie a2. Etwa bei einer Geschwindigkeit von 52 km/h schaltet das Getriebe in den dritten Gang und das Fahrzeug bewegt sich entlang einer Beschleunigungslinie a3.Normally, the motor vehicle moves in the unloaded state according to the acceleration line a 1 . At about 40 km / h, the automatic transmission shifts to second gear and the vehicle moves along an acceleration line a 2 . At about 52 km / h, the transmission shifts to third gear and the vehicle moves along an acceleration line a 3 .
Im
belasteten Zustand, beispielsweise bei einer Bergfahrt, ist die
Beschleunigung des Fahrzeugs im ersten Gang gegenüber dem
unbelasteten Zustand verringert. Dies äußert sich dadurch, dass die verfügbare Beschleunigung
mit steigender Geschwindigkeit rasch absinkt. Gemäß der Beschleunigungslinie
a1' wird
die Beschleunigung des Fahrzeugs ab einer Geschwindigkeit von ca.
32 km/h sogar negativ, d. h. es tritt eine Verzögerung auf. Das Fahrzeug würde sogar
langsamer. Die Erfindung sieht nun nicht mehr einen festen Schaltpunkt
bei beispielsweise 40 km/h vor, wie er im unbelasteten Zustand benötigt wird.
Vielmehr überprüft das erfindungsgemäße Getriebe
stets, ob beim Schalten in einen höheren Gang noch eine zumindest
gleiche Beschleunigung, besser aber eine etwas vergrößerte Beschleunigung
erreicht werden kann. Hierzu fragt das Getriebesteuergerät beim Motorsteuergerät entsprechende
benötigte
Informationen an. Wie man in
