Abstract
A control unit for a friction clutch or another torque transmitting system and/or for a transmission system in a motor vehicle employs an actor having an electric motor arranged to drive a single-stage or multi-stage transmission which, in turn, transmits motion to one or more mobile parts of the torque transmitting and/or transmission system by way of one or more output elements of the actor. The motor receives signals from one or more sensors and/or from the electronic circuitry in the vehicle and/or from a memory. At least one coil spring and/or another energy storing element is or can be provided to guarantee that the torque transmitting system assumes a predetermined (e.g., disengaged) condition and/or that the transmission system is in a predetermined gear ratio when the actor is not in use to change the magnitude of torque being (or to be) transmitted by the torque transmitting system and/or the ratio of the transmission system.
