    摘要: A method for checking the plausibility of an actuation position of a clutch of a double-clutch transmission operated by an actuator, including the following steps: disengaging the clutch assigned to the currently active old subtransmission and simultaneously engaging the clutch assigned to the other subtransmission to shift from the gear selected in the old subtransmission to a gear selected in the other, new subtransmission; deselecting the gear selected in the old subtransmission still during the overlapping operation of the clutches or immediately thereafter; detecting the difference between the speed of rotation of a drive shaft of the double-clutch transmission driven by a drive motor and the speed of rotation of the input shaft of the old subtransmission; and evaluating the state of the clutch assigned to the old subtransmission as disengaged when the difference in speeds of rotation exceeds a predetermined value within a predetermined time after deselection of the gear.

    摘要: A process for controlling a twin clutch transmission with two partial drive trains with respectively a friction clutch interposed between an internal combustion engine and the partial drive train is provided. If the transmission capacity of a friction clutch falls below the engine torque, engine intervention takes place. If the clutch temperature rises further above a default value, an emergency operation is initiated, in which the affected partial drive train is deactivated by opening the affected friction clutch, a preselection strategy used in the other partial drive train is changed and the other partial drive train is activated.
