Abstract
The invention relates to a method for controlling a dual clutch and a dual clutch housing two friction clutches which are each actuated independently of one another by means of a hydrostatic actuator. The hydrostatic actuator actuates the clutch as a function of a control signal of a control unit by means of a pressure which is applied to the actuation element and corresponds to a position of an actuation element of the friction clutch along an activation path. In order to sense a change in the position of the actuation element on one friction clutch which is brought about by the pressure on the actuation element of the other friction clutch, it is proposed to determine a correction variation for the purpose of compensating the changed position by means of a variable which represents the pressure of the disruptive hydrostatic actuator.
