  • Patent number: 6413189
    Abstract: 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 (Kv) of one travel direction to one clutch (Kr) 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 (VR,max), the speed of travel is automatically reduced to the maximum value first by continuous change of the ratio of the transmission (2) of the drive train.
