In a method for referencing the position of an actuating element of a functional unit, in particular of a clutch in the drivetrain of a vehicle, the attainment of a reference position of the actuating element is assessed for plausibility in that it is checked whether a variable which can be applied to the actuating element varies in a predetermined way in a predetermined spacing of the position of the actuating element from the reference position.

A process and device for the currentless referencing of a clutch position in non self-locking clutch actuating systems which are switched without current for a first predetermined, passive period of time or until an actuator standstill occurs, in order to verify a clutch reference position, then the clutch position achieved is determined by first measurement and current is supplied to the clutch actuating system for a predetermined, active period of time, the clutch actuating system being then switched again without current for another predetermined, passive period of time or until an actuator standstill occurs, the clutch position being determined by another measurement; finally the measured clutch position is checked to determine whether it can be verified as a new clutch reference position.

A method for the determination of a motor voltage limit, wherein a clutch actuator of an automated shift transmission remains motionless, including the steps of (a) raising or lowering a withstand voltage by an increment ΔU, starting from a current withstand voltage (Ucurr), and (b) determining whether the clutch actuator moves under the changed withstand voltage.

Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.

A method for controlling a clutch, especially a double clutch, an interruption-free manually controlled gearbox, especially a parallel gearbox. A common torque mapping for controlling the clutches is created according to the respective base torque mapping of each clutch. An interruption-free manually controlled gearbox, especially a parallel gearbox, for a vehicle having a double clutch, especially for carrying out said method. At least one control device produces a common torque mapping in order to control the double clutches according to the respective base torque mapping of each clutch.

摘要:
In a method for checking the auto-opening function of an actuator-operated clutch, the clutch is moved out of its closed position into its open position or out of its open position into its closed position by the actuator at a predetermined constant speed. During this movement of the clutch a force/distance curve is recorded; the point of the path at which the force is minimal is determined; and the clutch is moved to the determined path point by the actuator. The actuator is deactivated; and it is checked whether following deactivation of the actuator, the clutch returns into its open position in a predetermined manner.
