Abstract:
1. A method for setting a clutch torque of a clutch, which is disposed in a drive train of a motor vehicle, the clutch ( 1 ) being adjusted using a clutch actuator ( 7 ) that has at least two actuator parts that may be positioned relative to each other at raster values ( 9 a , 9 b , 9 c ) of a position raster, a position setpoint being determined for the actuator parts that corresponds to a clutch torque and is disposed between the raster values ( 9 a , 9 b , 9 c ) of the position raster, and the actuator parts being positioned relative to each other at a raster value ( 9 a ) of the position raster adjacent to the position setpoint, wherein a second position raster value ( 9 b ) is determined in addition to a first position raster value ( 9 a ) in such a manner that the position setpoint is disposed between the first position raster value ( 9 a ) and the second position raster value ( 9 b ), and the actuator parts are alternately positioned at the first position raster value ( 9 a ) and the second position raster value ( 9 b ) in such a manner that a average clutch torque more precisely matches the clutch torque setpoint than the clutch torques of the first and second position raster values ( 9 a , 9 b ).
