Abstract
In a method for setting the clutch torque of a clutch, especially a clutch disposed in a drive train of a motor vehicle, the clutch is adjusted using a clutch actuator. This clutch actuator has at least two actuator parts that may be positioned relative to each other at raster values of a position raster. A position setpoint corresponding to a clutch torque and disposed between the raster values of the position raster is calculated, and the actuator parts are positioned relative to each other at a raster value of the position raster that is adjacent to the position setpoint. In addition to the first position raster value, a second position raster value is calculated in such a manner that the position setpoint is disposed between the first position raster value and the second position raster value. The actuator parts are alternately positioned at the first position raster value and the second position raster value in such a manner that the average clutch torque more precisely matches the clutch torque setpoint than the clutch torques of the first and second position raster values.
