Aus den kontinuierlich berechneten Getriebemoment-Werten wird eine Matrix erstellt, in der für jeden Gang die Häufigkeit des Auftretens eines Getriebemoments in einer definierten Getriebemomentklasse eingetragen und abgespeichert wird. Vorzugsweise werden die jeweils abgespeicherten Werte der Matrix bei jedem Ausschaltvorgang des Kraftfahrzeug-Betriebs in einem nicht-flüchtigen Speicher abgelegt und für Getriebeneuentwicklungen fahrzeugextern ausgewertet.According to the invention, the transmission torque at the transmission input is continuously calculated from predetermined operating parameters to determine the load spectrum of a transmission for motor vehicles. From the continuously calculated gear torque values, a matrix is created in which the frequency of occurrence of a gear torque in a defined gear torque class is entered and stored for each gear. The respectively stored values of the matrix are preferably stored in a non-volatile memory at each switch-off operation of the motor vehicle operation and evaluated for vehicle developments outside of the vehicle.

Es ist Aufgabe der Erfindung, das Verfahren eingangs genannter Art in der Weise weiterzubilden, dass eine genauere Ermittlung des Lastkollektivs möglich ist.It Object of the invention, the method of the type mentioned develop in the way that a more accurate determination of the load collective possible is.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. Die abhängigen Patentansprüche sind vorteilhafte Weiterbildungen der Erfindung.These Object is achieved by the subject of claim 1. The dependent claims are advantageous developments of the invention.
Erfindungsgemäß wird zur Ermittlung des Lastkollektivs kontinuierlich das Getriebemoment am Getriebeeingang aus vorgegebenen Betriebsparametern berechnet. Aus den kontinuierlich berechneten Getriebemoment-Werten wird eine Matrix erstellt, in der für jeden Gang die Häufigkeit des Auftretens eines Getriebemoments in einer definierten Getriebemomentklasse eingetragen und abgespeichert wird.According to the invention to determine the load spectrum continuously the gear torque calculated at the transmission input from given operating parameters.

Die
Berechnung des Getriebemoments Md (= Drehmoment am Getriebeeingang)
für Handschalter erfolgt vorzugsweise auf Basis vom Motoristmoment
MMot, von der Motordrehzahl nMot und vom Massenträgheitsmoment
der Kurbelwelle nach folgendem Algorithmus:
Dieser
Algorithmus ist für Antriebsstränge mit Zweimassenschwungrad
(ZMS) im Frequenzbereich ≤ 10 Hz geeignet. Diese Begrenzung
ist einerseits durch die Abtastbegrenzung auf 100 Hz aufgrund der
gegebenen CPU Leistung derzeit verwendeter Motorsteuergeräte
vorgegeben und andererseits durch das Übertragungsverhalten
des ZMS, weil die Funktion des Verfahrens nur bei unterkritischem
ZMS-Betrieb gewährleistet ist. Den Vergleich vom bisher
verwendeten Motoristmoment MMot mit dem erfindungsgemäß berechneten
Getriebemoment Md, das nahezu gleich dem realen Getriebemoment ist,
veranschaulicht
Die
Berechnung des Getriebemoments für Automatikgetriebe mit
Wandler erfolgt auf Basis vom Motoristmoment, vom Massenträgheitsmoment
der Kurbelwelle, von der Motordrehzahl, vom Wandlerkupplungsmoment
(WK-Moment), von der Wandlerverstärkung, vom Massenträgheitsmoment
der Turbine und von der die Turbinendrehzahl nach folgendem Algorithmus:
Dieser
Algorithmus erlaubt bei Umsetzung in einem derzeit aktuellen Motor-
oder Getriebesteuergerät die Erfassung des Getriebemoments
Md am Getriebeeingang nach der Turbine im Frequenzbereich ≤ 10
Hz wegen der bereits erwähnten Abtastbegrenzung auf 100
Hz aufgrund der gegebenen CPU Leistung derzeit verwendeter Motorsteuergeräte.
Dabei hängt die Qualität der Formel-Ergebnisse maßgeblich von der Güte und Aufbereitung der basierenden Motorsignale im Motorsteuergerät ab.there depends on the quality of the formula results significantly of the quality and conditioning of the base engine signals in the engine control unit.
Bei der erfindungsgemäßen Berechnung des Getriebemoments in Form des in das Getriebe eingeleiteten Drehmoments werden die Trägheitsanteile zum Beschleunigen der Kurbelwelle einschließlich des Schwungrads und der Kupplung berücksichtigt. Außerdem wird der Wechselanteil der Getriebebelastung infolge der zyklischen Drehmomentabgabe des Hubkolbenmotors sowie aufgrund von Eigenformen des Antriebsstrangs, wie Ruckeln etc. erfasst. Durch die Anwendung des erfindungsgemäßen Algorithmus kann auf Basis von vorhandenen Signalen aus der Motorsteuerung ohne zusätzliche Drehmomentsensoren die Drehmomentbelastung des Getriebes im realen Fahrzeug flächendeckend mit hoher Qualität ermittelt werden. Damit ist eine exakte Dimensionierung und Auslegung des Getriebes möglich, was ggf. zur Gewichtsreduzierung und zu Kosteneinsparungen ohne Einbußen bei Funktion und Festigkeit führt.at the calculation of the transmission torque according to the invention in the form of the introduced into the transmission torque are the Inertia shares for accelerating the crankshaft including the Flywheel and the clutch considered. Furthermore becomes the alternating part of the transmission load due to the cyclic Torque output of the reciprocating engine and due to intrinsic forms of Powertrain, such as jerking, etc. recorded. By applying the The algorithm according to the invention can be based on existing signals from the engine control without additional Torque sensors the torque load of the gearbox in real Vehicle determined nationwide with high quality become. This is an exact dimensioning and interpretation of Gear possible, which may be necessary for weight loss and for cost savings without sacrificing function and strength leads.
