- the torque of the drive motor is set higher than the maximum torque transferable by the friction clutch by controlling or regulating the torque of the drive motor or that the torque of the drive motor is set to the maximum torque of the drive motor.
- the conditions are alternative or additional, that in the period of adjustment of the torque of the drive motor that slip is present in the clutch or in the period of adjustment of the predetermined slip by the control or regulation of the torque Drive motor or in the period between these two periods, the amount of a slip gradient of the slip does not exceed a predetermined slip gradient threshold.
- the predetermined slip is between 5 and 1000 revolutions per minute and preferably * is between 50 and 100 revolutions per minute.
- the predetermined slip is present for a predetermined period of time, wherein the period is between 1 and 100 seconds, and is preferably 10 to 15 seconds.
- the method is carried out cyclically and / or in a coupling process. In a further preferred embodiment of the invention, it is provided that the method is terminated when the temperature of the friction lining and / or Gegenlaufpart- ners friction lining of the friction clutch exceeds a third temperature threshold or if the maximum transmissible clutch torque of the friction clutch, the maximum engine torque or another predetermined target clutch torque threshold value is exceeded or reached.
- the second and third temperature threshold value is the optimum operating temperature of the clutch or of the friction lining and / or of the counterpart partner of the friction lining of the friction clutch or oriented to the optimum operating temperature.
- the second and third temperature threshold values are selected above or below the optimum operating temperature of the clutch or of the friction lining and / or the counter rotating partner of the friction lining of the friction clutch.
- the predetermined slip is predetermined as a function of the difference between the current operating temperature of the friction lining and / or the counterpart partner of the friction lining of the friction clutch to the optimum operating temperature.
- the strategy b) has the advantage over the strategy a) that the limiting engine intervention becomes active only when there is a physical problem. This is detected by unwanted slippage when the clutch is fully closed.
- the motor torque of the drive motor is set to a value - if necessary raised above the maximum transmissible clutch torque - so that slip safely in the clutch.
- the slip can also be adjusted by a slip control.
- a combination of slip control on the clutch and adjustment of engine torque is also possible to provide slip in the friction clutch
- Clutch temperature below a threshold e.g., 100 ° C
- clutch torque capacity e.g., activation only if the break is greater than x% of the maximum modestor torque, x may be 40%, for example
- the slip can be selected as a function of the difference of the current clutch temperature to the optimum operating temperature. That as the clutch temperature increases and the difference to the optimum operating temperature decreases, the slip is also reduced.
- the activation of the function to increase the clutch temperature can be linked to other operating conditions such.

- Eco mode the function does not become active; here one accepts the engine intervention to limit the engine torque, for example, according to the strategies a) or b).
- NVH effects noise, vibration, harshness effects, ie effects which cause the driver disturbing noises, vibrations or roughness
- Figure 1 is a schematic representation of an embodiment of the invention, wherein the maximum transmissible clutch torque despite slip and warm Kupplungsreibbelag not reach the maximum engine torque.
- Figure 2 is a schematic representation of an embodiment of the invention, wherein the maximum transmissible clutch torque by means of slip and warming Kupplungsreibbelag reaches the maximum engine torque.
- FIG. 1 and FIG. 2 show two further embodiments of the invention.
- the ordinate represents the time course of the method.
- the clutch is completely closed over the entire time profile shown.
- This measure can for example also be part of a method for calculating the maximum transferable clutch torque.
- the engine torque Trq Eng is raised only so far - for example, via the maximum transferable clutch torque Trq a - until Schupf (engine speed n mo t - transmission - input speed n ips ) is present in the fully closed clutch.
- This alternative measure can also be part of a method for calculating the maximum transferable clutch torque.
- the engine torque is then lowered back to 90% to 100%, for example 95% of the maximum transmittable clutch torque Trq a , so that the slip decreases.
- Trq a maximum transmittable clutch torque
- a small slip - for example, 50 to 100 revolutions per minute - is maintained by controlling the engine torque, so that energy is entered into the clutch, the Kupplungsreibbelag further heated, its coefficient of friction increases and the maximum transmittable clutch torque Trq a further increased.
- the duration of the maintenance of the low slip is dependent on the temperature of the Kupplungsreibbelags or Gegenlaufpartner the friction lining and is at a temperature of less than 100 degrees Celsius 10 to 15 seconds. This temperature value and the duration of the maintenance of the low slip is too suggestive, the concrete choice is left to the person skilled in the art, taking into account the technical single case, ie the present coupling and the Kupplungsreibbelags.
- Whether in the time range 30 by controlling the engine torque of the low slip is set or not, can be additionally linked to the criterion that the amount of slip gradient in the fall of the slip in the time range 20 on the low slip in the time range 30 exceeds a predetermined slip gradient threshold or not. If the absolute slip gradient does not exceed the threshold value in the event of slip, control of the engine torque takes place so that the low slip is set as described above and the maximum transmittable clutch torque Trq a is increased as a result of the heating.
- the concrete definition of the slip gradient threshold value is left to the person skilled in the art taking into account the individual technical case, for example the present clutch and the clutch friction lining. If the absolute slip gradient exceeds the threshold value in the case of slip drop, the small slip in the time range 30 is not set.
- the maximum transmittable clutch torque Trq a does not reach the maximum engine torque TrqEngMax in spite of slip and heating clutch friction lining during the period of low slip.
- the engine torque increases in the time domain 40 after the duration of the low slip limited so that there is no or only a very small slip of only a few revolutions per minute.
- the engine intervention for example until the next coupling process or until the next Verifier- event - continue to maintain.
- Verification event is the implementation of the method, for example, according to the embodiments of Figure 1 or Figure 2 understood.
- FIG. 2 shows a profile according to which the maximum transmittable clutch torque Trq C i is reached during the period of low slip maintenance due to the slip in the clutch and the heating clutch friction lining , the maximum engine torque Trq EngMax . The slip is then reduced to zero after reaching the maximum engine torque Trq EngM ax.
- the duration of the slip phase thus depends on the behavior of the coupling temperature.
- the above-described methods according to FIG. 1 or according to FIG. 2 are only executed if the temperature of the clutch friction lining or the counterpart partner of the friction lining is less than a predetermined temperature of, for example, 100 degrees Celsius.
- a predetermined temperature for example, 100 degrees Celsius.
- This temperature value is too much as a suggestion, the concrete choice is left to the expert, taking into account the technical case, ie the present coupling and the Kupplungsreibbelags. Above this temperature, no additional slip is introduced into the coupling by these methods. If the clutch is hot, a preventive engine intervention to protect the clutch is proposed.
- a Verometersereignis - ie the implementation of a method, for example, according to the embodiments of Figure 1 or Figure 2 is performed cyclically and / or in each coupling operation. The duration of such a cycle is left to the expert.
- a reduction of the engine intervention takes place 20 to 30 seconds after the reduction of the slip to zero 40 or nearly zero.
- a slip observer or a slip control must be active to respond to a recurrence of slippage.
- Slip phase duration depends on clutch temperature. Slip limitation due to engine torque reduction Slip low by controlling engine torque Slippage reduced to zero Permanent engine intervention until next clutching or until next verification event or engine engagement reduction 20 to 30 seconds after slippage reduction to zero with cyclic verification Maximum torque achieved, slip reduced to zero
