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.

[ What is claimed is:] [1.] An apparatus for controlling a torque transmitting system and a transmission in a power train of an automobile, the power train comprisingan engine having variable RPM, a torque transmitting system, a transmission including gear ratios, a control unit, at least one actuator, at least one electronic module comprising an engine electronic module and said control unit controls said engine electronic module to influence the engine RPM; and at least one sensor comprising a rotational-speed sensor;said torque transmitting system being operatively connected to a drive shaft to two wheels and wherein the rotational speed sensor is connected to at least one of said wheels;said control unit controls the at least one actuator for operating the torque transmitting system and for automatic shifting operation of the gear ratios of the transmission and said control unit is in signal-transmitting communication with the rotational speed sensor and the at least one electronic module;wherein for an automatic shifting operation of the gear ratios of the transmission by the at least one actuator the engine RPM is initially reduced to a desired RPM value by controlling the engine electronic via the control unit and subsequently the engine RPM is increased; andwherein the desired RPM value is determined from speed values derived from the rotational speed sensor and from one of the gear ratios in the transmission.
