Die Druckschrift
Der Erfindung liegt die Aufgabe zugrunde, den Beschleunigungsvorgang eines Fahrzeugs mit einem lastschaltbaren Stufengetriebe zu verbessern. Diese Aufgabe wird gelöst durch eine Regelungsanordnung nach Anspruch 1, ein Verfahren nach Anspruch 3, eine Datenverarbeitungsvorrichtung nach Anspruch 5 und ein Computerprogramm nach Anspruch 6. Bevorzugte Weiterbildungen sind in den Unteransprüchen enthalten und ergeben sich aus nachfolgender Beschreibung sowie dem in
Die Regelungsanordnung umfasst einen Regelkreis. Dessen Regelstrecke wird durch einen Motor gebildet. Insbesondere kann es sich um den Motor eines Fahrzeugs handeln. Der Motor ist etwa als Verbrennungsmotor oder als Elektromotor ausgeführt.The control arrangement includes a control circuit. Its controlled system is formed by a motor. In particular, it can be the engine of a vehicle. The motor is designed as an internal combustion engine or as an electric motor.
Der Regelkreis weist ein Stellglied auf, das auf den Motor und dessen Ausgangsleistung einwirkt. Handelt es sich bei dem Motor um einen Benzinmotor, dient eine Drosselklappe als Stellglied. Bei einem Dieselmotor fungieren dessen Einspritzdüsen als Stellglied.The control circuit has an actuator that acts on the engine and its output power. If the engine is a gasoline engine, a throttle valve serves as an actuator. In a diesel engine, its injectors act as an actuator.
Eine Ausgangsleistung des Motors, das heißt eine an einer Ausgangswelle des Motors anliegende Leistung wird als Regelgröße in den Regelkreis zurückgeführt. Der Motor wird über das Stellglied so geregelt, dass seine Ausgangsleistung einer als Führungsgröße vorgegebenen Leistung nachgeführt wird.An output power of the motor, ie a power applied to an output shaft of the motor, is fed back into the control loop as a controlled variable. The motor is controlled via the actuator in such a way that its output power is tracked to a power specified as a reference variable.
Erfindungsgemäß umfasst die Anordnung ein lastschaltbares Stufengetriebe. Dieses zeichnet sich durch mehrere fixe Übersetzungsstufen aus, zwischen denen unter Last umgeschaltet werden kann. Dies bedeutet, dass die jeweilige Übersetzungsstufe des Stufengetriebes geändert werden kann, während dessen Eingangswelle und Ausgangswelle mit einem Drehmoment beaufschlagt sind.According to the invention, the arrangement includes a power-shiftable step transmission. This is characterized by several fixed gear ratios, between which it is possible to switch under load. This means that the respective translation stage of the multi-stage transmission can be changed while its input shaft and output shaft are subjected to a torque.
Der Motor gibt seine Ausgangsleistung über das Stufengetriebe ab. Dies bedeutet, dass die Ausgangswelle des Motors triebwirksam, vorzugsweise drehfest mit der Eingangswelle des Stufengetriebes verbunden ist.The engine delivers its output power via the multi-stage gearbox. This means that the output shaft of the motor is connected to the input shaft of the stepped transmission in a drive-effective manner, preferably in a torque-proof manner.
Die Ausgangswelle des Stufengetriebes ist bevorzugt triebwirksam mit den Rädern einer oder mehrerer Achsen eines Fahrzeugs verbunden.The output shaft of the stepped transmission is preferably connected to the wheels of one or more axles of a vehicle in a drivingly effective manner.
Bei einem Schaltvorgang, das heißt einer Änderung der Übersetzungsstufe des Stufengetriebes, ändert sich die Drehzahl des Motors. Da dessen Ausgangsleistung als Regelgröße zurückgeführt wird, wird das Stellglied so angesteuert, dass ein Ausgangsdrehmoment des Motors entsprechend einer Regeldifferenz, das heißt einer Differenz zwischen der Führungsgröße und der Regelgröße, angepasst wird. Es resultiert eine gleichbleibende, ruckfreie Beschleunigung.The speed of the engine changes during a shifting process, i.e. a change in the gear ratio of the multi-step gearbox. Since its output power is fed back as a controlled variable, the actuator is controlled in such a way that an output torque of the motor is adjusted according to a control difference, ie a difference between the reference variable and the controlled variable. The result is constant, jerk-free acceleration.
Eine gleichbleibende, ruckfreie Beschleunigung korrespondiert in der Regel mit einem Fahrerwunsch, den der Fahrer über ein Bedienelement, gewöhnlich ein Fahrpedal, eingibt. Das Bedienelement ist Teil einer bevorzugten Weiterbildung. Über das Bedienelement wird die Führungsgröße des Regelkreises vorgegeben. Die Führungsgröße ist eindeutig, vorzugsweise eineindeutig von einer Stellung des Bedienelements abhängig.A constant, jolt-free acceleration generally corresponds to a driver's request, which the driver inputs via a control element, usually an accelerator pedal. The control element is part of a preferred development. The reference variable of the control loop is specified via the operating element. The reference variable is clearly, preferably one-to-one, dependent on a position of the operating element.
Ein erfindungsgemäßes Verfahren entspricht dem oben beschriebenen Verhalten der Regelungsanordnung. In einer bevorzugten Weiterbildung des Verfahrens wird der Regelkreis mit einer Störgröße beaufschlagt, die aus einem Gangwechsel, das heißt einer Änderung der Übersetzungsstufe des Stufengetriebes resultiert. Eine erfindungsgemäße Datenverarbeitungsvorrichtung ist angepasst, ein entsprechendes Verfahren auszuführen. Eine solche Anpassung erfolgt beispielsweise, indem ein erfindungsgemäßes Computerprogramm auf die Datenverarbeitungsvorrichtung geladen wird. Wenn das Computerprogramm von der Datenverarbeitungsvorrichtung ausgeführt wird, veranlasst es die Datenverarbeitungsvorrichtung, das erfindungsgemäße Verfahren oder eine bevorzugte Weiterbildung auszuführen.A method according to the invention corresponds to the behavior of the control arrangement described above. In a preferred further development of the method, the control loop is subjected to a disturbance variable which results from a gear change, ie a change in the gear ratio of the stepped transmission. A data processing device according to the invention is adapted to carry out a corresponding method. Such an adaptation takes place, for example, by loading a computer program according to the invention onto the data processing device. When the computer program is executed by the data processing device, it causes the data ver processing device to carry out the method according to the invention or a preferred further development.

Findet ein Schaltvorgang 109 statt, verändert sich die Getriebeübersetzung und damit die Motordrehzahl 101. Dies führt zu einer Differenz zwischen der Motordrehzahl 101 und der Solldrehzahl 107. Um dies auszugleichen und die Motordrehzahl 101 der Solldrehzahl 107 anzupassen, wird das Motordrehmoment erhöht. Die Folge ist eine ungewollte Beschleunigung, die der Fahrer durch Ändern der Fahrpedalstellung korrigieren muss.If a
