摘要： The invention relates to a method for reducing chatter vibrations of a friction clutch controlled automatically by a clutch actuator on the basis of a target clutch torque (M(s)) assigned to a clutch torque which is to be transmitted, which friction clutch is positioned in a drivetrain of a motor vehicle between an internal combustion engine and a transmission, having a present actual clutch torque which is marked by vibrations as a result of vibrations which occur occasionally (M(i)), wherein from a transmission behavior of the present actual clutch torque (M(i)) an absolute amplitude and a phase of an input signal detected at the output of the friction clutch and conveyed to a regulator are ascertained, from these a phase-selective disturbance torque is ascertained, from the latter a phase-correct correction torque (M(k)) is determined, and with this the target clutch torque (M(s)) is corrected by means of the regulator. In order to be able to design the method robustly, the correction torque (M(k)) is weighted with a specifiable intensification factor.

摘要： A method of estimating a torque of a transmission clutch may include adjusting an error, deducing an estimated engine angular speed and deducing an estimated clutch torque. The error may be adjusted by deducing an engine transient torque based on an engine angular speed measured using a sensor, an engine static torque deduced using a data map and a load torque depending on a driving load. The estimated engine angular speed may be deduced based on the engine static torque and the engine transient torque. The estimated clutch torque may be deduced by summing an integration value and an error compensation value. The integration value and the error compensation value may be deduced based on a difference between the estimated engine angular speed and the measured engine angular speed.

摘要： A torque transfer device for a motor vehicle includes a clutch for transferring torque between first and second shafts. An electromagnetic actuator includes an axially moveable armature for applying an application force to the clutch. An actuator control system includes a force sensor positioned within a clutch actuation force load path and is operable to output a signal indicative of a force applied to the clutch. The control system includes a controller operable to control the electromagnetic actuator to vary the force applied to the clutch based on the force sensor signal. As an option, the actuator control system can include a position sensor operable to output a signal indicative of a position of the armature. The control system determines a target torque to be transferred by the clutch and a target armature position based on a previously determined clutch torque vs. armature position relationship. The control system varies an electrical input to the electromagnetic actuator to perform closed loop control of the armature position.

摘要： Apparatus (control device) and a method for controlling a torque transmitting device such as a brake, wet clutch, dry clutch (10) during a filling and slip phase is provided, e.g. for coupling a first shaft (12) to a second shaft (14) via the wet clutch (10). A reference profile (52) for a control variable is provided, wherein the chronological progress of said control variable influences the position of a piston (22) for actuating clutch elements (16, 18). Each clutch element (16, 18) is connected to the first shaft (12) or the second shaft (14), with respect to a cylinder (20) of the wet clutch (10), and the control variable is determined during each coupling and a valve (38) for applying a pressure source to the piston (22) is operated, wherein the valve (38) is controlled during each coupling by means of a feed forward closed loop control (54) such that the control variable follows the reference profile (52). Due to the increased control quality by considering non-linear effects by means of the reference profile (52) for the feed forward closed loop control (54) at every coupling through learning, the coupling time can be shortened without increasing the risk of an uncomfortable coupling behavior.
