Abstract

The present invention relates to an apparatus and a method for automated controlling of an engageable and disengageable torque transmitting system and of a shifting a transmission in a power drive of a propulsion unit of an automotive vehicle, having at least one actuator for gear shifting and for operating the torque transmitting system, and having a control unit for controlling the at least one actuator and, further, having at least one sensor connected in signal-transmitting communication with a control unit. The sensor is arranged to operate between the control unit and the transmission and to monitor conditions in the transmission during automated shifting and to detect a predetermined condition while the system is disengaged and, upon detection of such predetermined condition, to undo, at least temporarily and at least partially, the preceding gear shifting, and to thereafter resume gear shifting.
