A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.

Clutch actuator and method for the control thereof

The invention relates to a smart actuator for actuating a clutch having a communication interface for connecting to a higher-level control unit, and at least one data line for connecting to the higher-level control unit, where the smart actuator is configured to identify errors in the higher-level control unit and/or an assigned second smart actuator, and where the smart actuator has controlling means that are suitable for converting the controlled system into a safe system state in the case of a recognized error. Furthermore, the invention relates to a corresponding control method and a control system in which the smart actuators and the method are used.
