Abstract

A method for controlling an automated friction clutch that is located between a drive motor and a transmission in a motor vehicle that is equipped with fraction control and driving condition recognition for detecting current driving conditions.

Claims (17)

1. A method for controlling an automated friction clutch arranged between a drive engine and a transmission in a motor vehicle with slippage regulation and driving situation detection for detecting a currently provided driving situation, wherein the slippage regulation is only activated in at least one of the following driving conditions:

after startup,

during temperature changes of the clutch,

after wear adjustment,

after starting up the motor vehicle,

during creeping,

during stopping, wherein the slippage activation criterion is fulfilled when the amount of the slippage is above a threshold value which is between 10 and 100 revolutions per minute, preferably 30 revolutions per minute.

2. The method according to claim 1 , wherein a periodic activation of the slippage regulation is provided when no slippage regulation is activated.

3. The method according to claim 1 , wherein an activation of the slippage regulation is performed during load changes when a degree of quantification with respect to the drive pedal actuation exceeds a threshold value.

4. The method according to claim 1 , wherein a preload portion of the clutch control is reduced when the clutch control is activated during a load change.

5. A device for controlling an automated friction clutch, arranged between a drive motor and a transmission in a motor vehicle, with slippage regulation and a driving situation detection for determining a currently provided driving situation, wherein the slippage regulation is only activateable at least in one of the following driving conditions:

after startup,

during temperature changes of the clutch,

after wear adjustment,

after starting up the motor vehicle,

during creeping,

during stopping, wherein the slippage activation criterion is fulfilled when the amount of the slippage is above a threshold value which is between 10 and 100 revolutions per minute, preferably 30 revolutions per minute.
