ABSTRACT:
The present invention relates to an apparatus and a method for controlling the operation of an engageable and disengable torque transmitting system and of an automated transmission that is connected to a differential and to the torque transmitting system by an input shaft. The system and the transmission are disposed in a power train of a motor vehicle having variable-speed drive unit, and the transmission is shiftable into any one of a plurality of gears. The torque transmitting system and the automated transmission comprise a control unit and at least one actuator arranged to vary the extent of engagement of the torque transmitting system and to shift the transmission into a selected gear. Further, there are means for transmitting signals between the control unit and the drive unit to controllably reduce the speed of said drive unit in response to at least one initial stage of automated shifting of said transmission into a selected gear and to controllably increase the speed of said drive unit during a next-following stage of automated shifting of said transmission into said selected gear.
