Abstract
Die Erfindung betrifft ein Verfahren zum Schalten eines automatisierten Getriebes eines Fahrzeuges, vorzugsweise eines Motorrades, bei welchem eine Momentenfreimachung eines Triebstrangs und ein Gangwechsel erfolgt, wobei nach Abschluss des Gangwechsels der Triebstrang mit einem Motormoment beaufschlagt wird. Zur Verkürzung der Zeit des Gangwechsels werden die Momentenfreimachung des Triebstranges und der Gangwechsel gleichzeitig ausgeführt.The invention relates to a method for shifting an automated transmission of a vehicle, preferably a motorcycle, in which torque is released from a drive train and a gear change is carried out, with an engine torque being applied to the drive train after the gear change has been completed. To shorten the time of the gear change, the torque release of the drive train and the gear change are carried out simultaneously.
Description
Die Erfindung betrifft ein Verfahren zum Schalten eines automatisierten Getriebes eines Fahrzeuges, vorzugsweise eines Motorrades, bei welchem eine Momentenfreimachung eines Triebstrangs und ein Gangwechsel erfolgt, wobei nach Abschluss des Gangwechsels der Triebstrang mit einem Motormoment beaufschlagt wird.The invention relates to a method for shifting an automated transmission of a vehicle, preferably a motorcycle, in which a drive train is released for torque and a gear change takes place, with an engine torque being applied to the drive train after the gear change has been completed.
Bei automatisierten Getrieben von Kraftfahrzeugen, insbesondere PKW's, ist es bekannt, dass bei einem Schaltvorgang eine Schiebemuffe auf einer Getriebeeingangswelle bewegt wird. Dazu muss das Getriebe weitestgehend kraftfrei sein. Dies wird durch das Öffnen einer Kupplung erreicht (
Beim Fahren eines Motorrades mit automatisierten Schaltgetrieben legt der Fahrer meistens Wert auf eine möglichst kurze Schaltdauer, wobei auf die Vermeidung von Beschleunigungsspitzen verzichtet wird.When driving a motorcycle with automated gearboxes, the driver usually attaches great importance to the shortest possible gearshift time, while avoiding acceleration peaks.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Schalten eines automatisierten Getriebes mit einer kurzen Schaltdauer anzugeben.The invention has for its object to provide a method for shifting an automated transmission with a short shift duration.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass die Momentenfreimachung des Triebstranges und der Gangwechsel gleichzeitig ausgeführt werden. Dies hat den Vorteil, dass eine Ansteuerung eines Aktors, der die Kupplung öffnet und eine Ansteuerung des Aktors, welcher eine Kraft auf eine Schiebemuffe im Getriebe verlagert, zeitgleich ausgeführt wird. Diese gleichzeitige Ansteuerung dieser Teilsoftwareroutinen führt zu einer Verringerung der Zeitdauer des Schaltvorganges, was ein sportliches Fahren des Fahrzeuges unterstützt.According to the invention, the object is achieved in that the torque release of the drive train and the gear change are carried out simultaneously. This has the advantage that actuation of an actuator that opens the clutch and actuation of the actuator that displaces a force on a sliding sleeve in the transmission are carried out simultaneously. This simultaneous activation of these sub-software routines leads to a reduction in the duration of the switching process, which supports sporty driving of the vehicle.
Vorteilhafterweise wird die Momentenfreimachung des Triebstranges abgebrochen, wenn der Gangwechsel beendet ist. Somit kann bei dieser parallelen Ausführung der beiden Vorgänge ein Gangwechsel beendet sein, bevor die Kupplung vollständig geöffnet ist. Dies führt zu einer weiteren Verkürzung des Schaltvorganges.Advantageously, the drive train torque release is terminated when the gear change is complete. In this parallel execution of the two processes, a gear change can thus be completed before the clutch is fully opened. This leads to a further shortening of the switching process.
In einer Ausführungsform wird zur Momentenfreimachung des Triebstranges eine Kupplung geöffnet. Dies stellt den üblicherweise gebräuchlichen Vorgang zur Vorbereitung eines Schaltvorganges dar.In one embodiment, a clutch is opened to release the drive train torque. This is the usual process for preparing a shift.
In einer Variante wird nach Beendigung des Gangwechsels die Kupplung wieder geschlossen. Das Schließen der Kupplung erfolgt auch dann, wenn die Kupplung noch nicht vollständig geöffnet ist. Voraussetzung für das Schließen der Kupplung ist lediglich die Beendigung des Gangwechsels.In a variant, the clutch is closed again after the gear change has been completed. The clutch is also closed when the clutch is not yet fully open. The only requirement for closing the clutch is the completion of the gear change.
In einer Weiterbildung wird zur Momentenfreimachung des Triebstranges das Motormoment bei geschlossener Kupplung auf null gesetzt. Bei dieser Ausführung wird die Kupplung gar nicht betätigt, sondern nur der Verbrennungsmotor angesteuert.In a further development, the engine torque is set to zero when the clutch is closed in order to release the drive train. In this version, the clutch is not actuated at all, only the combustion engine is actuated.

In einem Motorrad wird zur Einlegung eines Ganges eine Kraft an einer Schiebemuffe im Getriebe aufgebaut, was durch einen Getriebeaktor in Form eines Antriebsmotors erreicht wird. Die Schiebemuffe wird sich erst dann bewegen, wenn die Kraftübertragung ein gewisses Niveau unterschreitet. Um den Schaltvorgang möglichst auf eine kurze Zeitdauer auszulegen, wird der Ablauf in einem Softwareprozess dahingehend geändert, dass die eine Kupplung bzw. die Schaltmuffen ansteuernden Aktoren zeitgleich angesteuert werden. Dies ist in
