摘要： A method for hysteresis compensation in an actuator and a selector fork that is adjustable by this actuator and guides a sliding sleeve, by means of a state machine, wherein the selector fork is moved by means of the actuator from a first shift position (xDecoup), namely a neutral position, into at least one second shift position (xCoup), namely a gear position, and vice versa, wherein the position of the actuator (phiAtr, phiCoup, phiDecoup), in the event of a shift request into the neutral position (xDecoup) or into the gear position (xCoup), is corrected on the basis of stored mechanical backlash (phiBL) between the actuator and the selector fork and of a sign (+1, 0, −1) generated by the state machine and associated with the particular shift request.

摘要： The present invention relates to a method for correcting a drag torque curve of at least one rotatable machine element of which the drag torque is dependent on the rotational speed of the machine element, wherein the drag torque curve has a plurality of rotational speed ranges which are different from one another, in which the drag torque curve in each rotational speed range is corrected between a measured rotational speed of the machine element and a calculated rotational speed of the machine element on the basis of a rotational speed deviation in the respective rotational speed range.
