Abstract

The method involves determining a driving path data, reference speed and acceleration of a motor vehicle provided by a user, and determining a transmission ratio necessary for an optimal driving operation and minimal energy consumption. The ratio is changed, when the ratio exceeds or falls below a permissible value in a determined cycle time based on a rotational speed, torque and performance of an engine to be estimated from position gradients and the path and a user reference value sensor (8). A transmission-reference value processor calculates another transmission ratio. An independent claim is also included for a device for implementing an automatic transmission controlling method.

Description

Die Erfindung geht aus von einem Verfahren nach der Gattung des Hauptanspruchs. Nach dem Stand der Technik werden die Motorkenndaten und das automatische Getriebe eines Kraftfahrzeuges lastabhängig in Verbindung mit dem von dem Benutzer vorgegebenen Sollwert geregelt. Der Benutzer wählt über einen Wählhebel eine bestimmtes Schaltprogramm aus. Dieses Schaltprogramm wiederum wählt in Abhängigkeit von einem individuellen Sollwert, der Motorlast und der gefahrenen Geschwindigkeit die Motorkenndaten, wie bspw. Leistung, Zündzeitpunkt etc sowie eine vorgegebene Übersetzung des Getriebes in mehreren Schaltstufen, d.h die Motorkenndaten werden sollwert-, last- und geschwindigkeitsabhängig gemäß einer manuellen Vorwahl geregelt. Die Regelung der Daten innerhalb des gewählten Schaltprogramms erfolgt ausschließlich auf der Basis von Echtzeitparametern, d.h. die Motorsteuerung und Schaltung reagiert auf Sprünge oder Impulse in den Soll- oder Istwerten auch dann, wenn die Sollwert- oder Istwertabweichungen im Mittel gering ausfallen. Insbesondere bei Kraftfahrzeugen mit Verbrennungsmotor führt die manuelle Vorwahl des Schaltprogramms in Verbindung mit den vorgegeben Motorkenndaten, sowie die schnelle Reaktion auf Soll- und Istwertabweichungen, zu einer hohen Schaltzahl mit wechselnder Motorlast und Motordrehzahl und in der Folge zu erhöhtem Energieverbrauch bei vermindertem Komfort.The The invention is based on a method according to the preamble of the main claim. In the prior art, the engine characteristics and the automatic Transmission of a motor vehicle load-dependent in conjunction with the regulated by the user setpoint. The user chooses one selector lever a specific circuit program.

The regulation of the data within the selected circuit program takes place exclusively based on real-time parameters, i. the engine control and Circuit responds to jumps or impulses in the nominal or Actual values even if the setpoint or actual value deviations to be low on average. Especially in motor vehicles with internal combustion engine leads the Manual preselection of the switching program in conjunction with the specified motor characteristics, as well as the fast response to setpoint and actual value deviations, too a high number of gears with changing engine load and engine speed and subsequently to increased Energy consumption with reduced comfort.

Nach einer weiteren, vorteilhaften Ausgestaltung des Verfahrens wird aufgrund der Daten des Positionsbestimmungssystems die Qualität des Weges im weitesten Sinne bestimmt und hieraus in Verbindung mit der Istgeschwindigkeit die zu erwartende Beschleunigung berechnet. Aufgrund dieser voraussichtlichen Beschleunigung und der daraus resultierenden zu erwartenden Motorlast werden die Sollwerte der Motorkenndaten sowie die Übersetzung des automatischen Getriebes, die Schaltstufe, gewählt.To a further advantageous embodiment of the method is based on the data of the positioning system, the quality of the path in the determined in the broadest sense and from this in connection with the actual speed calculates the expected acceleration.
