  • Method and apparatus for the generation of a setting signal for an actuator of a clutch unit of a motor vehicle
    Patent number: 8463514
    Abstract: A method and control system for an actuator of a clutch of a motor vehicle includes a main control unit determining a desired value for a torque to be transmitted in dependence on predetermined first parameters. A setting signal for the actuator corresponding to the desired value is generated by an additional control unit on the basis of the determined desired value. A desired value tolerance range for the determined desired value of the torque is determined by the main control unit in dependence on predetermined second parameters. The additional control unit determines an actual value of the torque transmissible by the clutch unit and generates a new setting signal for the actuator when the actual value is outside the desired value tolerance range.
