Description

Verfahren zum Ansteuern eines automatisierten Schaltgetriebes  Method for controlling an automated gearbox
Die vorliegende Erfindung betrifft ein Verfahren zum Ansteuern eines automatisierten Schaltgetriebes gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. The present invention relates to a method for driving an automated gearbox according to the closer defined in the preamble of claim 1. Art.
Beispielsweise aus der Druckschrift DE 101 05 749 A1 ist ein Verfahren für ein erleichtertes Rangieren in einem Nutzfahrzeug mit einem automatisiert schaltenden Schaltgetriebe bekannt. Bei aktivierter Rangierhilfe des Fahrzeuges werden in Abhängigkeit von der Stellung des Fahrpedals und dem Beladungszustand des Fahrzeuges die Kupplung und die Betriebsreibungsbremse durch Signale eines Bordrechners des Fahrzeuges gleichzeitig und aufeinander abgestimmt automatisch betätigt. For example, from the document DE 101 05 749 A1 discloses a method for easier maneuvering in a commercial vehicle with an automated shifting manual transmission is known. When the maneuvering aid of the vehicle is activated, the clutch and the service friction brake are automatically actuated by signals from an on-board computer of the vehicle simultaneously and in coordination with one another, depending on the position of the accelerator pedal and the loading state of the vehicle.
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren der eingangs beschriebenen Gattung vorzuschlagen, mit dem das Rangierverhalten des Fahrzeuges weiter optimiert wird. The invention is based on the object to propose a method of the type described above, with the Rangierverhalten of the vehicle is further optimized.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich insbesondere aus den Unteransprüchen und der Zeichnung. This object is achieved by the features of claim 1. Further advantageous embodiments will become apparent in particular from the dependent claims and the drawing.
Erfindungsgemäß wird somit ein Verfahren zum Ansteuern eines automatisierten Schaltgetriebes eines Fahrzeuges, insbesondere eines Nutzfahrzeuges vorgeschlagen, bei dem über einen Fahrschalter oder dergleichen einer Steuerelektronik verschiedene Fahrmodi zum Bewegen des Fahrzeuges und zumindest ein Rangiermodus zum Rangieren des Fahrzeuges eingestellt werden können, wobei bei aktiviertem Rangiermodus manuell die Fahrzeugmasse eingegeben wird. According to the invention a method for driving an automated gearbox of a vehicle, in particular a commercial vehicle is proposed, in which via a drive switch or the like of control electronics different driving modes for moving the vehicle and at least one Rangiermodus can be set for maneuvering the vehicle, with manual Rangiermodus manually the vehicle mass is entered.
Auf diese Weise kann ein verbessertes Rangierverhalten z.B. beim langsamen Rangieren eines schwer beladenen Nutzfahrzeuges an einer Rampe oder an einem Hang mit dem erfindungsgemäßen Ansteuerverfahren deutlich verbessert werden, ohne dass die Steuerelektronik verändert werden muss. Dazu kann in bekannter Weise über einen Fahrschalter oder dergleichen der Rangiermodus zunächst aktiviert beziehungsweise angewählt werden, so dass nun das Getriebe z. B. aus dem Automatik oder dem manuellen Fahrmodus in den Rangiermodus verstellt wird. Im Rangiermodus wird dann zum Beispiel über den Fahrschalter die aktuelle Gewichtsangabe des Fahrzeuges von dem Fahrer manuell gewählt. Somit kann das Fahrzeug dann mit reduzierten Parametern in Abhängigkeit der eingegebenen Fahrzeugmasse rangiert beziehungsweise angefahren werden. Somit ist ein besonders feinfühliges Bewegen des Fahrzeuges möglich. In this way, improved maneuvering behavior, for example during slow maneuvering of a heavily loaded utility vehicle on a ramp or on a slope, can be markedly improved with the actuation method according to the invention, without the control electronics has to be changed. These can be activated or selected in a known manner via a drive switch or the like the Rangiermodus initially, so that now the transmission z. B. from the automatic or the manual drive mode in the maneuvering mode is adjusted. In the maneuvering mode, the current weight specification of the vehicle is then selected manually by the driver, for example via the drive switch. Thus, the vehicle can then be ranked or approached with reduced parameters depending on the input vehicle mass. Thus, a particularly sensitive movement of the vehicle is possible.
Gemäß einer bevorzugten Weiterbildung der Erfindung kann vorgesehen sein, dass dem Fahrer der aktivierte Rangiermodus zum Beispiel in einem Display angezeigt wird. Es ist zusätzlich möglich, dass auch neben dem Rangiermodus zum Beispiel die eingegebene Gewichtsangabe ebenfalls in dem Display angezeigt wird. According to a preferred embodiment of the invention can be provided that the driver of the activated maneuvering mode is displayed for example in a display. It is also possible that in addition to the shunting mode, for example, the entered weight is also displayed in the display.
Im Rahmen einer vorteilhaften Ausführungsvariante der Erfindung, kann vorgesehen sein, dass bei aktiviertem Rangiermodus die Fahrzeuggeschwindigkeit, die Kupplungstemperatur oder dergleichen überwacht werden. Es können weitere Parameter während des Rangiermodus beobachtet werden. Wenn beispielsweise die Fahrzeuggeschwindigkeit einen vorbestimmten Grenzwert überschreitet und somit nicht mehr als Rangiergeschwindigkeit gewertet werden kann oder die Kupplungstemperatur über einen vorbestimmten Grenzwert ansteigt, kann zum Beispiel vorgesehen sein, dass der Rangiermodus automatisch deaktiviert wird, um gefährliche Fahrsituationen zu vermeiden und auch Schäden z. B. an der Kupplung zu verhindern. Der Fahrer kann vorzugsweise über die automatische Deaktivierung des Rangiermodus zum Beispiel visuell in dem Display oder auch akustisch gewarnt werden. In the context of an advantageous embodiment variant of the invention, it can be provided that, when the maneuvering mode is activated, the vehicle speed, the clutch temperature or the like are monitored. Other parameters can be observed during the shunting mode. For example, if the vehicle speed exceeds a predetermined threshold and thus can not be counted as Rangiergeschwindigkeit or the clutch temperature rises above a predetermined limit, for example, be provided that the maneuvering mode is automatically disabled to avoid dangerous driving situations and damage z. B. to prevent the clutch. The driver can preferably be warned visually via the automatic deactivation of the maneuvering mode, for example visually in the display or acoustically.
Um die erfindungsgemäße Ansteuerstrategie des Rangiermodus weiter zu verbessern, kann vorgesehen sein, dass bei betätigtem Fahrpedal im Rahmen des Rangiermodus eine Schaltverhinderung aktiviert wird, um dann das Anfahren mit reduzierter Anfahrdrehzahl und reduziertem Kupplungsmoment durchzuführen. Bei dem erfindungsgemäßen Verfahren kann auch vorgesehen sein, dass der Rangiermodus von dem Fahrer manuell zum Beispiel über den Fahrschalter deaktiviert wird. In order to further improve the control strategy of the maneuvering mode according to the invention, it can be provided that, when the accelerator pedal is actuated, a switching prevention is activated in the context of the maneuvering mode, in order to then carry out the approach with reduced starting speed and reduced coupling torque. In the method according to the invention it can also be provided that the maneuvering mode is deactivated manually by the driver, for example via the travel switch.
Nachfolgend wird die Erfindung näher anhand der Zeichnungen erläutert. Es zeigen: The invention will be explained in more detail with reference to the drawings. Show it:
Figur 1 ein Ablaufdiagramm einer möglichen Ausführungsvariante eines erfindungsgemäßen Verfahrens zum Ansteuern eines automatisierten Schaltgetriebes; und FIG. 1 shows a flow diagram of a possible embodiment variant of a method according to the invention for controlling an automated gearbox; and
Figur 2 ein Ablaufdiagramm mit einem manuellen Ausstieg aus dem Rangiermodus im Rahmen des erfindungsgemäßen Verfahrens. 2 shows a flowchart with a manual exit from the shunting mode in the context of the method according to the invention.
In den Figuren ist ein mögliches Ausführungsbeispiel eines Verfahrens dargestellt, das bei einer Steuerung eines automatisierten Schaltgetriebes vorzugsweise eines Nutzfahrzeuges angewendet wird, um verschiedene Fahrmodi einzustellen. Das automatisierte Getriebe besteht üblicherweise aus einer elektromechanischen Kupplungssteuerung und einer ebenfalls elektromechanischen Getriebesteuerung die über eine Steuerelektronik ansteuerbar sind, welche auch mit einer Steuerelektronik des Fahrzeugmotors über ein Fahrzeugnetzwerk in Verbindung steht. Die verschiedenen Fahrmodi können über einen Fahrschalter, der mit der Steuerelektronik verbunden ist, angewählt werden. Beispielsweise kann unter anderem ein Automatikmodus, ein manueller Fahrmodus und auch ein Rangiermodus ausgewählt werden. In the figures, a possible embodiment of a method is shown, which is used in a control of an automated gearbox, preferably a commercial vehicle, to set different driving modes. The automated transmission usually consists of an electromechanical clutch control and a likewise electromechanical transmission control which can be controlled via an electronic control unit, which is also connected to a control electronics of the vehicle engine via a vehicle network. The various driving modes can be selected via a travel switch, which is connected to the control electronics. For example, an automatic mode, a manual driving mode and also a shunting mode can be selected among other things.
Wie insbesondere aus dem Ablaufdiagramm gemäß Figur 1 verdeutlicht ist, kann bei inaktivem Rangiermodus der Fahrer über den Fahrschalter den Rangiermodus anwählen. Der angewählte Rangiermodus wird dem Fahrer in einem Display angezeigt. Nun wird im Rahmen des Verfahrens überprüft, ob die Fahrzeuggeschwindigkeit VFahrz einer Rangiergeschwindigkeit entspricht und die Kupplungstemperatur TκupP unterhalb eines vorgegebenen Grenzwertes GW liegt. Wenn eine dieser Bedingungen nicht zutrifft, wird der Rangiermodus deaktiviert. Wenn die vorgenannten Be- dingungen gegeben sind, kann der Fahrer erfindungsgemäß über den Fahrschalter, zum Beispiel über so genannte Tipp+ - und Tipp- -Tasten die aktuelle Fahrzeugmasse eingegeben. Dieses eingegebene Fahrzeuggewicht wird dem Fahrer ebenfalls in dem Display angezeigt. As can be seen in particular from the flow chart according to FIG. 1, when the maneuvering mode is inactive, the driver can select the maneuvering mode via the travel switch. The selected maneuvering mode is displayed to the driver in a display. Now it is checked in the context of the method, whether the vehicle speed V fa hrz corresponds to a maneuvering speed and the clutch temperature Tκup P is below a predetermined limit value GW. If one of these conditions does not apply, the shunting mode is deactivated. If the abovementioned Given conditions are given, the driver can according to the invention via the driving switch, for example via so-called tip + - and typing buttons enter the current vehicle mass. This entered vehicle weight is also displayed to the driver in the display.
Danach wird von dem erfindungsgemäßen Verfahren überprüft, ob das Fahrpedal betätigt wird. Wenn dies nicht der Fall ist, kehrt das Verfahren zu dem Verfahrensschritt zurück, bei dem die Fahrgeschwindigkeit VFahrz und die Kupplungstemperatur TKupp überprüft werden. Wenn jedoch das Fahrpedal betätigt wird, kann eine Schaltverhinderung im Rahmen des Rangiermodus aktiviert werden, so dass die Gangmenge begrenzt wird. Daraufhin wird das Anfahren mit reduzierten Parametern durchgeführt. Dabei werden die Motoranfahrdrehzahl und das Kupplungsmoment an die Laststellung und an das eingegebene Fahrzeuggewicht angepasst. Thereafter, it is checked by the method according to the invention, whether the accelerator pedal is actuated. If this is not the case, the method returns to the method step in which the vehicle speed V Fa hrz and the clutch temperature T Ku pp are checked. However, when the accelerator pedal is operated, a shift inhibition can be activated in the shunting mode, so that the gear amount is limited. Thereupon the starting is carried out with reduced parameters. The motor starting speed and the clutch torque are adapted to the load position and the entered vehicle weight.
Im Allgemeinen werden sowohl die Motoranfahrdrehzahl als auch das Kupplungsmoment reduziert, um ein feinfühligeres Rangieren zu ermöglichen. Während des Rangierens kann der Fahrer jederzeit die Gewichtseingabe über den Fahrschalter verändern. Dies wird in dem Ablaufdiagramm dadurch angedeutet, dass das Verfahren zu dem Verfahrensschritt zurückkehrt, beidem die Fahrzeuggeschwindigkeit VFahrz und die Kupplungstemperatur TKupp überprüft werden. In general, both the engine starting speed and the clutch torque are reduced to allow more sensitive maneuvering. During maneuvering, the driver can change the weight input via the travel switch at any time. This is indicated in the flowchart in that the method returns to the method step in which the vehicle speed V Fa hrz and the clutch temperature T Ku pp are checked.
In Figur 2 ist ein Ablaufdiagramm für einen manuellen Ausstieg aus dem gewählten Rangiermodus im Rahmen des erfindungsgemäßen Verfahrens gezeigt. Hierbei wird kein automatischer Ausstieg bei Überschreiten der Fahrzeuggeschwindigkeit Vpahrz oder der Kupplungstemperatur TKupp durchgeführt, sondern der Fahrer ändert den Modus manuell über den Fahrschalter, um den Rangiermodus zu deaktivieren. Bezuqszeichen FIG. 2 shows a flow diagram for a manual exit from the selected shunting mode in the context of the method according to the invention. In this case, no automatic exit is carried out when the vehicle speed Vp ahrz or the clutch temperature T Ku pp is exceeded, but the driver manually changes the mode via the drive switch in order to deactivate the maneuvering mode.
