Definitions

  • the present invention relates to a method for driving an automated gearbox according to the closer defined in the preamble of claim 1. Art.
  • the invention is based on the object to propose a method of the type described above, with the Rangier of the vehicle is further optimized.
  • 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.
  • 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.
  • 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 Rangier für 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.
  • 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.
  • the maneuvering mode is deactivated manually by the driver, for example via the travel switch.
  • FIG. 1 shows a flow diagram of a possible embodiment variant of a method according to the invention for controlling an automated gearbox
  • FIG. 2 shows a flowchart with a manual exit from the shunting mode in the context of the method according to the invention.
  • 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.
  • the driver can select the maneuvering mode via the travel switch.
  • the selected maneuvering mode is displayed to the driver in a display.
  • the vehicle speed V fa hrz corresponds to a maneuvering speed and the clutch temperature T ⁇ up 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.
  • the method 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.
  • a shift inhibition can be activated in the shunting mode, so that the gear amount is limited.
  • 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.
  • both the engine starting speed and the clutch torque are reduced to allow more sensitive 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.
  • 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.
  • 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.
