Method and device for actuating a motor vehicle clutch device

Method and device for controlling a motor vehicle drive train. To reverse the travel direction, the input torque is transmitted with pressure modulation from one clutch (K ) of one travel direction to one clutch (K ) of the opposite travel direction. If at the time that a reverse travel direction is selected and the speed of travel exceeds a set maximum value (V ), the speed of travel is automatically reduced to the maximum value first by continuous change of the ratio of the transmission ( ) of the drive train.
