Definitions

  • the invention relates to a method for controlling a sailing operation of a vehicle with automated clutch, in which a vehicle-specific parameter is determined, which is compared with a threshold value, depending on the comparison with the threshold, an entry into or an exit from the sailing operation is determined ,
  • a control method for motor vehicles with automated coupling device is known in which the vehicle is placed in a sailing operation. Sailing is a deliberate disengagement in deceleration phases of the vehicle to understand in which neither the accelerator pedal as a fuel feed rated element nor the brake pedal is pressed.
  • This sailing mode essentially serves to save fuel. In this case, the vehicle rolls, wherein the vehicle driving the engine is either off or is operated at an idle speed.
  • the clutch is opened under control by the electronic control unit when the gear is engaged, so that the vehicle rolls without losing kinetic energy due to the braking effect of the engine.
  • the sailing mode is usually terminated by operation of a brake or the accelerator pedal.
  • the invention has for its object to provide a method for controlling a sailing operation of a vehicle with automated clutch, in which the decision on the entry or exit in the sailing operation is made in terms of technically effective criteria.
  • the object is achieved in that a vehicle-specific parameter is selected for the comparison, which is partially influenced by an actuation state of at least one accelerator pedal.
  • a driver's desired accelerator pedal position of zero is applied during the entry into the sailing operation to a control unit of the engine. Even if the driver still has his foot on the gas pedal and presses it, the sailing mode is already approved by the actual accelerator pedal position is not forwarded to the control unit.
  • Fig. 1 shows an embodiment of an apparatus for carrying out the method according to the invention
  • Fig. 2 shows an embodiment of the method according to the invention.
  • the term "sailing” is to be understood below as meaning the automated opening of the clutch, in particular while the vehicle is being driven, the additional option being to switch off the internal combustion engine during sail operation
  • the control strategy for the sailing operation stored in the control unit 1 globally regulates the opening and closing of the clutch independently of the driver's operation as well as the switching off or on of an internal combustion engine driving the vehicle.
  • the control unit 1 comprises three logic units 2, 3, 4.
  • the first logic unit is a sail start logic unit 2, which is connected to a motor logic unit 3. Parallel to the sail start logic unit 2, a sail end logic unit 4 is present, which decides on switching off the sailing process. All three logic units 2, 3, 4 are independent input signals available by each logic unit 2, 3, 4 is directly connected to a first sensor unit 5 for outputting a vehicle-specific parameter and a second sensor unit 6 for displaying the driving condition of the vehicle ,

Abstract

L'invention concerne un procédé de commande d'un mode de marche en roue libre d'un véhicule à embrayage automatisé, selon lequel un paramètre spécifique du véhicule est déterminé, ledit paramètre est comparé à une valeur seuil, une entrée en mode de marche en roue libre ou une sortie de mode de marche en roue libre étant déterminée en fonction du résultat de la comparaison avec la valeur seuil. Dans ce procédé selon lequel la décision d'entrer en mode de marche en roue libre ou d'en sortir est prise uniquement sur la base de faits techniques, un paramètre spécifique du véhicule est sélectionné pour la comparaison, lequel est influencé en partie par un état d'actionnement d'au moins une pédale d'accélérateur.
